um have contracts<00:01:32.320> um<00:01:32.799> well<00:01:33.000> we<00:01:33.119> are<00:01:33.280> going<00:01:33.479> to<00:01:33.680> start 00:01:34.149 --> 00:01:34.159 align:start position:0% contracts um well we are going to start 00:01:34.159 --> 00:01:37.749 align:start position:0% contracts um well we are going to start with<00:01:34.479> like<00:01:35.479> the<00:01:35.680>

align:start position:0% with like the basics with the definition that<00:01:37.960> you<00:01:38.040> can<00:01:38.240> find<00:01:38.479> on<00:01:38.640> the<00:01:38.960> website<00:01:39.960> so 00:01:40.190 --> 00:01:40.200 align:start position:0% that you can find on the website so 00:01:40.200 --> 00:01:41.789 align:start position:0% that you can find on the website so basically<00:01:40.640> Huff<00:01:40.960> is<00:01:41.079> a<00:01:41.200> low-level 00:01:41.789 --> 00:01:41.799 align:start position:0% basically Huff is a low-level 00:01:41.799 --> 00:01:44.149

run<00:01:47.560> on<00:01:47.799> the<00:01:48.079> evm<00:01:49.079> so<00:01:49.840> well<00:01:50.040> since<00:01:50.320> you 00:01:50.510 --> 00:01:50.520 align:start position:0% that run on the evm so well since you 00:01:50.520 --> 00:01:52.469 align:start position:0% that run on the evm so well since you guys<00:01:50.680> are<00:01:51.079> experts<00:01:51.560> you<00:01:51.680> know<00:01:51.920> exactly<00:01:52.320> what 00:01:52.469 --> 00:01:52.479 align:start position:0% guys are experts you know exactly what 00:01:52.479 --> 00:01:55.310 align:start position:0% guys are experts you know exactly what this<00:01:52.759> means<00:01:53.759> but<00:01:54.040> maybe<00:01:54.320> it<00:01:54.399> would<00:01:54.640> be<00:01:54.799> a<00:01:54.960> bit 00:01:55.310 --> 00:01:55.320 align:start position:0% this means but maybe it would be a bit 00:01:55.320 --> 00:01:58.550 align:start position:0% this means but maybe it would be a bit obscure<00:01:55.840> or<00:01:56.280> isoteric<00:01:56.920> for<00:01:57.200> some<00:01:57.479> people<00:01:58.200> so 00:01:58.550 --> 00:01:58.560 align:start position:0% obscure or isoteric for some people so 00:01:58.560 --> 00:02:02.069 align:start position:0% obscure or isoteric for some people so we<00:01:58.719> can<00:01:59.960> have<00:02:00.039> a<00:02:00.159> look<00:02:00.399> like<00:02:00.560> a<00:02:00.680> deeper<00:02:01.079> look<00:02:01.320> so 00:02:02.069 --> 00:02:02.079 align:start position:0% we can have a look like a deeper look so 00:02:02.079 --> 00:02:04.670 align:start position:0% we can have a look like a deeper look so when<00:02:02.240> it<00:02:02.439> comes<00:02:02.719> to<00:02:03.360> Smart<00:02:03.719> contract 00:02:04.670 --> 00:02:04.680 align:start

00:02:25.270 align:start position:0% it you can use for example like inline assembly<00:02:22.720> so<00:02:23.440> just<00:02:23.680> like<00:02:23.959> adding<00:02:24.360> some 00:02:25.270 --> 00:02:25.280 align:start position:0% assembly so just like adding some 00:02:25.280 --> 00:02:27.229 align:start position:0% assembly so just like adding some assembly<00:02:25.879> like<00:02:26.080> this<00:02:26.280> like<00:02:26.400> on<00:02:26.599> top<00:02:26.800> of<00:02:26.920> your 00:02:27.229 --> 00:02:27.239 align:start position:0% assembly like this like on top of your 00:02:27.239 --> 00:02:29.910 align:start position:0% assembly like this like on top of your solidity<00:02:27.879> code<00:02:28.440> you<00:02:28.599> can<00:02:28.800> lose<00:02:29.360> like<00:02:29.599> a 00:02:29.910 --> 00:02:29.920 align:start position:0% solidity code you can lose like a 00:02:29.920 --> 00:02:33.270 align:start position:0% solidity code you can lose like a solidity<00:02:30.480>

high level then<00:03:13.480> here<00:03:13.680> we<00:03:13.879> have<00:03:14.159> something<00:03:15.159> a<00:03:15.239> a<00:03:15.360> bit<00:03:15.519> more 00:03:15.830 --> 00:03:15.840 align:start position:0% then here we have something a a bit more 00:03:15.840 --> 00:03:17.910 align:start position:0% then here we have something a a bit more interesting<00:03:16.400> so<00:03:16.599> here<00:03:16.799> we're<00:03:17.000> using<00:03:17.400> inline 00:03:17.910 --> 00:03:17.920 align:start position:0% interesting so here we're using inline 00:03:17.920 --> 00:03:21.110 align:start position:0% interesting so here we're using inline assembly<00:03:18.760> so<00:03:19.000> we<00:03:19.120> are<00:03:19.319> trying<00:03:19.640> to<00:03:20.519> double<00:03:21.000> a 00:03:21.110 --> 00:03:21.120 align:start position:0% assembly so we are trying to double a 00:03:21.120 --> 00:03:23.470 align:start position:0% assembly so we are trying to double a little<00:03:21.400> bit<00:03:21.680> with<00:03:21.879> the 00:03:23.470 --> 00:03:23.480 align:start position:0% little bit with the 00:03:23.480 --> 00:03:27.670 align:start position:0% little bit with the evm<00:03:24.480> um<00:03:25.239> pretty<00:03:25.599> straightforward<00:03:26.519> also<00:03:27.440> just 00:03:27.670 --> 00:03:27.680 align:start position:0% evm um pretty straightforward also just 00:03:27.680 --> 00:03:30.509 align:start position:0% evm um pretty straightforward also just some<00:03:28.159> uh<00:03:28.640> different<00:03:29.000> ways<00:03:29.239> to<00:03:29.480> to<00:03:29.599> do 00:03:30.509 --> 00:03:30.519 align:start position:0% some uh different ways to to do 00:03:30.519 --> 00:03:34.550 align:start position:0% some uh different ways to to do things<00:03:31.519> this<00:03:31.680> will<00:03:31.920> be<00:03:32.480> the<00:03:33.040> complete 00:03:34.550 --> 00:03:34.560 align:start position:0% things this will be the complete 00:03:34.560 --> 00:03:38.070 align:start position:0% things this will be the complete um<00:03:35.560> assembly<00:03:36.319> or<00:03:36.599> uu<00:03:37.200> so<00:03:37.360> it's<00:03:37.560> like<00:03:37.799> the 00:03:38.070 --> 00:03:38.080 align:start position:0% um assembly or uu so it's like the 00:03:38.080 --> 00:03:41.550 align:start position:0% um assembly or uu so it's like the Standalone<00:03:39.040> assembly<00:03:40.040> uh<00:03:40.280> version<00:03:40.799> so<00:03:41.080> it's 00:03:41.550 --> 00:03:41.560 align:start position:0% Standalone assembly uh version so it's 00:03:41.560 --> 00:03:44.030 align:start position:0% Standalone assembly uh version so it's we<00:03:41.760> have<00:03:41.920> a<00:03:42.040> bit<00:03:42.239> more<00:03:42.519> code<00:03:42.879> but<00:03:43.519> things<00:03:43.720> are 00:03:44.030 --> 00:03:44.040 align:start position:0% we have a bit more code but things are 00:03:44.040 --> 00:03:45.830 align:start position:0% we have a bit more code but things are still<00:03:44.360> like<00:03:45.000> a<00:03:45.120> bit 00:03:45.830 --> 00:03:45.840 align:start position:0% still like a bit 00:03:45.840 --> 00:03:48.270 align:start position:0% still like a bit simple<00:03:46.840> uh<00:03:47.120> then<00:03:47.480> yeah<00:03:47.599> if<00:03:47.720> you<00:03:47.799> want<00:03:47.959> to<00:03:48.120> have 00:03:48.270 --> 00:03:48.280 align:start position:0% simple uh then yeah if you want to have 00:03:48.280 --> 00:03:51.110 align:start position:0% simple uh then yeah if you want to have some<00:03:48.560> fun<00:03:48.799> you<00:03:48.959> have<00:03:49.239> like<00:03:49.599> uh<00:03:50.280> the<00:03:50.599> memonic 00:03:51.110 --> 00:03:51.120 align:start position:0% some fun you have like uh the memonic 00:03:51.120 --> 00:03:52.910 align:start position:0% some fun you have like uh the memonic bite<00:03:51.360> code<00:03:51.680> with<00:03:51.840> just<00:03:52.040> like<00:03:52.360> all<00:03:52.599> the 00:03:52.910 --> 00:03:52.920 align:start position:0% bite code with just like all the 00:03:52.920 --> 00:03:55.429 align:start position:0% bite code with

00:04:00.319 align:start position:0% compiler will output you can also write 00:04:00.319 --> 00:04:04.149 align:start position:0% compiler will output you can also write this<00:04:00.519> by<00:04:00.680> hand<00:04:01.319> but<00:04:01.519> it<00:04:02.120> might<00:04:02.319> take<00:04:02.480> some 00:04:04.149 --> 00:04:04.159 align:start position:0% this by hand but it might take some 00:04:04.159 --> 00:04:07.190 align:start position:0% this by hand but it might take some time<00:04:05.159> so<00:04:05.439> now<00:04:05.640> you<00:04:06.000> you<00:04:06.159>

align:start position:0% um bear with me wire strudel I don't know<00:04:42.199> what<00:04:42.400> this<00:04:42.520> means<00:04:43.199> but<00:04:43.360> that<00:04:43.479> was<00:04:43.600> the 00:04:43.749 --> 00:04:43.759 align:start position:0% know what this means but that was the 00:04:43.759 --> 00:04:45.870 align:start position:0% know what this means but that was the

and basically just 00:04:45.880 --> 00:04:48.350 align:start position:0% name of the contract and basically just like<00:04:46.080> a<00:04:46.360> elliptic<00:04:46.840> curve<00:04:47.479> something<00:04:47.919> similar 00:04:48.350 --> 00:04:48.360 align:start position:0% like a elliptic curve something similar 00:04:48.360 --> 00:04:51.590 align:start position:0% like a elliptic

align:start position:0% to zcash and they they they wanted to 00:04:51.600 --> 00:04:54.350 align:start position:0% to zcash and they they they wanted to write<00:04:51.919> this<00:04:52.320> in<00:04:52.520> solidity<00:04:53.199> they<00:04:53.360> tried<00:04:53.680> it<00:04:53.919> but 00:04:54.350 --> 00:04:54.360 align:start position:0% write this in solidity they tried it but 00:04:54.360 --> 00:04:56.150 align:start position:0% write this in solidity they tried it but the<00:04:54.520> results<00:04:54.919> were<00:04:55.120> not<00:04:55.360> convincing<00:04:56.000> they 00:04:56.150 --> 00:04:56.160 align:start position:0% the results were not convincing they 00:04:56.160 --> 00:04:58.629 align:start position:0% the results were not convincing they tried<00:04:56.360> to<00:04:56.479> use<00:04:56.720> some<00:04:57.160> assembly<00:04:58.039> but<00:04:58.240> still<00:04:58.520> it 00:04:58.629 --> 00:04:58.639 align:start position:0% tried to use some assembly but still it 00:04:58.639 --> 00:05:00.189 align:start position:0% tried to use some assembly but still it wasn't<00:04:59.080> there<00:04:59.320> so 00:05:00.189 --> 00:05:00.199 align:start position:0% wasn't there so 00:05:00.199 --> 00:05:02.469 align:start position:0% wasn't there so they<00:05:00.320> started<00:05:00.680> to<00:05:00.880> think<00:05:01.479> about<00:05:01.840> making<00:05:02.240> some 00:05:02.469 --> 00:05:02.479 align:start position:0% they started to think about making some 00:05:02.479 --> 00:05:05.110 align:start position:0% they started to think about making some kind<00:05:02.639> of<00:05:02.919> way<00:05:03.120> to<00:05:03.320> be<00:05:03.440> able<00:05:03.720> to<00:05:03.919> write<00:05:04.280> assembly 00:05:05.110 --> 00:05:05.120 align:start position:0% kind of way to be able to write assembly 00:05:05.120 --> 00:05:08.870 align:start position:0% kind of way to be able to write assembly but<00:05:05.320> with<00:05:05.639> extra<00:05:06.479> function<00:05:07.080> extra<00:05:07.880> features 00:05:08.870 --> 00:05:08.880 align:start position:0% but with extra function extra features 00:05:08.880 --> 00:05:11.550 align:start position:0% but with extra function extra features and<00:05:09.000> so<00:05:09.240> this<00:05:09.400> is<00:05:10.320> uh<00:05:10.520> how<00:05:10.759> they<00:05:10.960> came<00:05:11.199> with<00:05:11.400> the 00:05:11.550 --> 00:05:11.560 align:start position:0% and so this is uh how they came with the 00:05:11.560 --> 00:05:15.670 align:start position:0% and so this is uh how they came with the idea<00:05:12.000> of<00:05:12.280> writing<00:05:12.800> half<00:05:13.639> of<00:05:14.039> making 00:05:15.670 --> 00:05:15.680 align:start position:0% idea of writing half of making 00:05:15.680 --> 00:05:19.950 align:start position:0% idea of writing half of making half<00:05:16.680> so<00:05:17.440> this<00:05:17.600> is<00:05:17.919> like<00:05:18.600> uh<00:05:18.840> the<00:05:19.400> I<00:05:19.520> think<00:05:19.759> the 00:05:19.950 --> 00:05:19.960 align:start position:0% half so this is like uh the I think the 00:05:19.960 --> 00:05:23.270 align:start position:0% half so this is like uh the I think the first<00:05:20.520> half<00:05:20.919> code<00:05:21.280> ever<00:05:21.720> written<00:05:22.600> so<00:05:22.880> you<00:05:23.000> can 00:05:23.270 --> 00:05:23.280 align:start position:0% first half code ever written so you can 00:05:23.280 --> 00:05:26.430 align:start position:0% first half code ever written so you can see<00:05:24.280> it's<00:05:24.479> still<00:05:25.199> it<00:05:25.319> looks<00:05:25.639> like<00:05:25.800> a<00:05:25.960> bit<00:05:26.280> what 00:05:26.430 --> 00:05:26.440 align:start position:0% see it's still it looks like a bit what 00:05:26.440 --> 00:05:28.909 align:start position:0% see it's still it looks like a bit what we<00:05:26.680> have<00:05:26.960> now<00:05:27.520> some<00:05:27.759> stuff<00:05:28.080> were<00:05:28.400> removed<00:05:28.840> I 00:05:28.909 --> 00:05:28.919 align:start position:0% we have now some stuff were removed I 00:05:28.919 --> 00:05:30.790 align:start position:0% we have now some stuff were removed I think<00:05:29.199> like<00:05:29.479> uh<00:05:29.800> yeah<00:05:30.000> like<00:05:30.160> template<00:05:30.680> we 00:05:30.790 --> 00:05:30.800 align:start position:0% think like uh yeah like template we 00:05:30.800 --> 00:05:33.270 align:start position:0% think like uh yeah like template we don't<00:05:31.000> have<00:05:31.199> this<00:05:31.400> anymore<00:05:32.160> but<00:05:32.560> most<00:05:32.840> of<00:05:33.080> the 00:05:33.270 --> 00:05:33.280 align:start position:0% don't have this anymore but most of the 00:05:33.280 --> 00:05:35.189 align:start position:0% don't have this anymore but most of the the<00:05:33.400> things<00:05:33.680> are<00:05:33.919> still<00:05:34.240> there<00:05:34.479> up<00:05:34.600> to<00:05:34.960> up<00:05:35.039> to 00:05:35.189 --> 00:05:35.199 align:start position:0% the things are still there up to up to 00:05:35.199 --> 00:05:36.830 align:start position:0% the things are still there up to up to this 00:05:36.830 --> 00:05:36.840 align:start position:0% this 00:05:36.840 --> 00:05:40.309 align:start position:0% this date<00:05:37.840> but<00:05:38.400> when<00:05:38.680> Aztec<00:05:39.160> decided<00:05:39.560> to<00:05:39.759> create 00:05:40.309 --> 00:05:40.319 align:start position:0% date but when Aztec decided to create 00:05:40.319 --> 00:05:42.550 align:start position:0% date but when Aztec decided to create half<00:05:40.759> they<00:05:40.960> had<00:05:41.160> like<00:05:41.400> very<00:05:41.800> different 00:05:42.550 --> 00:05:42.560 align:start position:0% half they had like very different 00:05:42.560 --> 00:05:45.670 align:start position:0% half they had like very different intentions<00:05:43.160> at<00:05:43.479> what<00:05:43.639> we<00:05:43.880> have<00:05:44.160> now<00:05:44.919> and<00:05:45.400> like 00:05:45.670 --> 00:05:45.680 align:start position:0% intentions at what we have now and like 00:05:45.680 --> 00:05:47.950 align:start position:0% intentions at what we have now and like I<00:05:45.840> think<00:05:46.080> I<00:05:46.199> took<00:05:46.520> this<00:05:46.720> quote<00:05:47.080> from<00:05:47.400> their<00:05:47.639> R 00:05:47.950 --> 00:05:47.960 align:start position:0% I think I took this quote from their R 00:05:47.960 --> 00:05:50.309 align:start position:0% I think I took this quote from their R me<00:05:48.199> actually<00:05:48.800> so<00:05:49.039> they<00:05:49.160> said<00:05:49.440> like<00:05:49.800> half<00:05:50.080> was 00:05:50.309 --> 00:05:50.319 align:start position:0% me actually so they said like half was 00:05:50.319 --> 00:05:52.230 align:start position:0% me actually so they said like half was designed<00:05:50.680> with<00:05:50.800> a<00:05:50.960> complete<00:05:51.400> disregard<00:05:51.960> for 00:05:52.230 --> 00:05:52.240 align:start position:0% designed with a complete disregard for 00:05:52.240 --> 00:05:55.909 align:start position:0% designed with a complete disregard for semantics<00:05:53.240> safety<00:05:53.800> or<00:05:54.000> basic<00:05:54.560> consistency<00:05:55.560> so 00:05:55.909 --> 00:05:55.919 align:start position:0% semantics safety or basic consistency so 00:05:55.919 --> 00:05:58.150 align:start position:0% semantics safety or basic consistency so any<00:05:56.199> similarities<00:05:56.840> to<00:05:57.080> production<00:05:57.560> code<00:05:57.919> are 00:05:58.150 --> 00:05:58.160 align:start position:0% any similarities to production code are 00:05:58.160 --> 00:06:00.909 align:start position:0% any similarities to production code are purly<00:05:58.720> incidental<00:05:59.720> and<00:05:59.960> have<00:06:00.199> should<00:06:00.479> on<00:06:00.680> new 00:06:00.909 --> 00:06:00.919 align:start position:0% purly incidental and have should on new 00:06:00.919 --> 00:06:04.230 align:start position:0% purly incidental and have should on new account<00:06:01.160> be<00:06:01.280> used<00:06:01.639> by<00:06:02.199> anybody<00:06:03.199> so<00:06:03.880> yeah<00:06:04.120> this 00:06:04.230 --> 00:06:04.240 align:start position:0% account be used by anybody so yeah this 00:06:04.240 --> 00:06:07.749 align:start position:0% account be used by anybody so yeah this is<00:06:04.759> more<00:06:04.919> or<00:06:05.120> less<00:06:05.360> what<00:06:05.960> they<00:06:06.960> said<00:06:07.360> about 00:06:07.749 --> 00:06:07.759 align:start position:0% is more or less what they said about 00:06:07.759 --> 00:06:09.550 align:start position:0% is more or less what they said about have<00:06:08.080> they<00:06:08.240> just<00:06:08.360> wanted<00:06:08.680> to<00:06:08.840> build<00:06:09.120> this<00:06:09.280> tool 00:06:09.550 --> 00:06:09.560 align:start position:0% have they just wanted to build this tool 00:06:09.560 --> 00:06:12.029 align:start position:0% have they just wanted to build this tool for<00:06:09.800> them<00:06:10.280> and<00:06:10.400> the<00:06:10.560> goal<00:06:10.800> was<00:06:10.960> not<00:06:11.120> to<00:06:11.759> really 00:06:12.029 --> 00:06:12.039 align:start position:0% for them and the goal was not to really 00:06:12.039 --> 00:06:14.070 align:start position:0% for them and the goal was not to really to<00:06:12.240> spread<00:06:12.560> it<00:06:12.680> it<00:06:12.800> was<00:06:13.000> open<00:06:13.280> source<00:06:13.639> but<00:06:13.960> it 00:06:14.070 --> 00:06:14.080 align:start position:0% to spread it it was open source but it 00:06:14.080 --> 00:06:17.749 align:start position:0% to spread it it was open source but it was<00:06:14.280> not<00:06:14.479> meant<00:06:14.720> to<00:06:14.840> be<00:06:15.039> like 00:06:17.749 --> 00:06:17.759 align:start position:0% 00:06:17.759 --> 00:06:20.950 align:start position:0% shared<00:06:18.759> but<00:06:19.240> what<00:06:19.479> happened<00:06:19.919> so<00:06:20.280> we<00:06:20.400> know<00:06:20.680> that 00:06:20.950 --> 00:06:20.960 align:start position:0% shared but what happened so we know that 00:06:20.960 --> 00:06:23.589 align:start position:0% shared but what happened so we know that obviously<00:06:21.360> if<00:06:21.479> you're<00:06:21.720> here<00:06:22.160> today<00:06:23.160> uh<00:06:23.360> like 00:06:23.589 --> 00:06:23.599 align:start position:0% obviously if you're here today uh like 00:06:23.599 --> 00:06:26.390 align:start position:0% obviously if you're here today uh like the<00:06:23.800> the<00:06:24.000> story<00:06:24.639> and<00:06:24.840> like<00:06:25.039> the<00:06:25.160> road<00:06:25.639> that 00:06:26.390 --> 00:06:26.400 align:start position:0% the the story and like the road that 00:06:26.400 --> 00:06:29.350 align:start position:0% the the story and like the road that that<00:06:26.560> was<00:06:26.840> like<00:06:27.039> taken<00:06:27.840> is<00:06:28.120> quite<00:06:28.759> quite<00:06:29.039> big 00:06:29.350 --> 00:06:29.360 align:start position:0% that was like taken is quite quite big 00:06:29.360 --> 00:06:31.790 align:start position:0% that was like taken is quite quite big and<00:06:29.680> actually<00:06:30.120> have<00:06:30.440> evolved<00:06:30.880> a<00:06:31.000> lot<00:06:31.319> since 00:06:31.790 --> 00:06:31.800 align:start position:0% and actually have evolved a lot since 00:06:31.800 --> 00:06:34.870 align:start position:0% and actually have evolved a lot since then<00:06:32.800> uh<00:06:33.199> one<00:06:33.479> day<00:06:33.759> like<00:06:33.919> some<00:06:34.120> guy<00:06:34.319> decided<00:06:34.680> to 00:06:34.870 --> 00:06:34.880 align:start position:0% then uh one day like some guy decided to 00:06:34.880 --> 00:06:36.909 align:start position:0% then uh one day like some guy decided to write<00:06:35.400> to<00:06:35.560> take<00:06:35.720> the<00:06:35.880> code<00:06:36.160> and<00:06:36.319> write<00:06:36.639> like<00:06:36.800> a 00:06:36.909 --> 00:06:36.919 align:start position:0% write to take the code and write like a 00:06:36.919 --> 00:06:39.510 align:start position:0% write to take the code and write like a new<00:06:37.120> compiler<00:06:37.599> in<00:06:37.840> JavaScript<00:06:38.840> and<00:06:39.160> some 00:06:39.510 --> 00:06:39.520 align:start position:0% new compiler in JavaScript and some 00:06:39.520 --> 00:06:41.430 align:start position:0% new compiler in JavaScript and some people<00:06:39.880> decided<00:06:40.280> to<00:06:40.440> write<00:06:40.840> then<00:06:41.080> a<00:06:41.199> new 00:06:41.430 --> 00:06:41.440 align:start position:0% people decided to write then a new 00:06:41.440 --> 00:06:43.950 align:start position:0% people decided to write then a new compiler<00:06:41.880> in<00:06:42.080> typescript<00:06:43.080> and<00:06:43.280> more<00:06:43.599> people 00:06:43.950 --> 00:06:43.960 align:start position:0% compiler in typescript and more people 00:06:43.960 --> 00:06:45.830 align:start position:0% compiler in typescript and more people came<00:06:44.240> and<00:06:44.440> they<00:06:44.639> decided<00:06:45.039> to<00:06:45.160> write<00:06:45.440> a<00:06:45.599> brand 00:06:45.830 --> 00:06:45.840 align:start position:0% came and they decided to write a brand 00:06:45.840 --> 00:06:48.510 align:start position:0% came and they decided to write a brand new<00:06:46.039> compiler<00:06:46.479> in<00:06:46.680> Rust<00:06:47.440> and<00:06:47.639> then<00:06:48.199> more 00:06:48.510 --> 00:06:48.520 align:start position:0% new compiler in Rust and then more 00:06:48.520 --> 00:06:50.870 align:start position:0% new compiler in Rust and then more people<00:06:48.960> came<00:06:49.199> and<00:06:49.479> they<00:06:49.680> said<00:06:50.319> maybe<00:06:50.680> it's 00:06:50.870 --> 00:06:50.880 align:start position:0% people came and they said maybe it's 00:06:50.880 --> 00:06:52.629 align:start position:0% people came and they said maybe it's time<00:06:51.039> to<00:06:51.199> write<00:06:51.440> like<00:06:51.599> a<00:06:51.759> new<00:06:52.000> compiler<00:06:52.479> in 00:06:52.629 --> 00:06:52.639 align:start position:0% time to write like a new compiler in 00:06:52.639 --> 00:06:55.350 align:start position:0% time to write like a new compiler in Rust<00:06:53.080> again<00:06:53.319> like<00:06:53.560> from<00:06:53.720> scratch<00:06:54.520> so<00:06:54.960> we<00:06:55.120> have 00:06:55.350 --> 00:06:55.360 align:start position:0% Rust again like from scratch so we have 00:06:55.360 --> 00:06:57.510 align:start position:0% Rust again like from scratch so we have like<00:06:55.599> many<00:06:56.440> different<00:06:56.840> people<00:06:57.240> many 00:06:57.510 --> 00:06:57.520 align:start position:0% like many different people many 00:06:57.520 --> 00:06:59.950 align:start position:0% like many different people many different<00:06:58.039> contributors<00:06:59.039> uh<00:06:59.199> just<00:06:59.319> to<00:06:59.759> this 00:06:59.950 --> 00:06:59.960 align:start position:0% different contributors uh just to this 00:06:59.960 --> 00:07:02.629 align:start position:0% different contributors uh just to this picture<00:07:00.360> from<00:07:00.879> GitHub<00:07:01.360> I<00:07:01.479> think<00:07:02.039> many<00:07:02.280> of<00:07:02.479> them 00:07:02.629 --> 00:07:02.639 align:start position:0% picture from GitHub I think many of them 00:07:02.639 --> 00:07:05.670 align:start position:0% picture from GitHub I think many of them are<00:07:02.879> missing<00:07:03.280> but<00:07:03.400> it's<00:07:03.639> like<00:07:04.120> maybe<00:07:04.400> the<00:07:04.560> main 00:07:05.670 --> 00:07:05.680 align:start position:0% are missing but it's like maybe the main 00:07:05.680 --> 00:07:07.990 align:start position:0% are missing but it's like maybe the main contributors<00:07:06.680> uh<00:07:06.840> that<00:07:07.080> contributed<00:07:07.680> to<00:07:07.840> the 00:07:07.990

uh<00:07:09.120> many<00:07:09.400> other<00:07:09.680> people<00:07:10.039> contributed<00:07:10.720> to 00:07:11.189 --> 00:07:11.199 align:start position:0% core uh many other people contributed to 00:07:11.199 --> 00:07:14.270 align:start position:0% core uh many other people contributed to other<00:07:11.520> things<00:07:11.879> like<00:07:12.199> writing<00:07:12.800> libraries<00:07:13.800>

like<00:07:14.800> making<00:07:15.400> uh<00:07:16.280> I<00:07:16.360> don't<00:07:16.479> know<00:07:16.639> like<00:07:16.879> writing 00:07:17.270 --> 00:07:17.280 align:start position:0% like making uh I don't know like writing 00:07:17.280 --> 00:07:19.990 align:start position:0% like making uh I don't know like writing articles<00:07:17.840> or<00:07:18.039> making<00:07:18.360>

articles or making presentations to have but<00:07:20.160> this<00:07:20.280> is<00:07:20.400> more<00:07:20.560> or<00:07:20.720> less<00:07:21.000> like 00:07:21.749 --> 00:07:21.759 align:start position:0% but this is more or less like 00:07:21.759 --> 00:07:24.909 align:start position:0% but this is more or less like a<00:07:22.759> all<00:07:22.960> the<00:07:23.120> people<00:07:23.400> that 00:07:24.909 --> 00:07:24.919 align:start position:0% a all the people that 00:07:24.919 --> 00:07:28.350 align:start position:0% a all the people that contributed<00:07:25.919> and<00:07:26.199> this<00:07:26.759> is<00:07:27.759> what<00:07:27.919> I<00:07:28.039> showed 00:07:28.350 --> 00:07:28.360 align:start position:0% contributed and this is what I showed 00:07:28.360 --> 00:07:31.909 align:start position:0% contributed and this is what I showed you<00:07:28.720> earlier<00:07:29.319> in<00:07:29.520> in<00:07:29.840> solidities<00:07:30.840> or<00:07:31.080> in<00:07:31.280> Viper 00:07:31.909 --> 00:07:31.919 align:start position:0% you earlier in in solidities or in Viper 00:07:31.919 --> 00:07:34.629 align:start position:0% you earlier in in solidities or in Viper and<00:07:32.120> this<00:07:32.199> is<00:07:32.440> like<00:07:32.680> the<00:07:32.879> same<00:07:33.319> code<00:07:33.639> in<00:07:33.919> half 00:07:34.629 --> 00:07:34.639 align:start position:0% and this is like the same code in half 00:07:34.639 --> 00:07:38.869 align:start position:0% and this is like the same code in half so<00:07:35.000> as<00:07:35.120> you<00:07:35.240> can<00:07:35.400> see<00:07:35.840> it's<00:07:36.560> not<00:07:37.560> that<00:07:37.800> big<00:07:38.080> is 00:07:38.869 --> 00:07:38.879 align:start position:0% so as you can see it's not that big is 00:07:38.879 --> 00:07:41.350 align:start position:0% so as you can see it's not that big is it's<00:07:39.080> maybe<00:07:39.400> a<00:07:39.520> bit<00:07:39.720> scary<00:07:40.199> but<00:07:40.440> we<00:07:40.560> don't<00:07:40.840> have 00:07:41.350 --> 00:07:41.360 align:start position:0% it's maybe a bit scary but we don't have 00:07:41.360 --> 00:07:44.350 align:start position:0% it's maybe a bit scary but we don't have much<00:07:41.720> code<00:07:42.080> actually<00:07:42.680> it's<00:07:42.879> kind<00:07:43.039> of<00:07:43.360> simple 00:07:44.350 --> 00:07:44.360 align:start position:0% much code actually it's kind of simple 00:07:44.360 --> 00:07:46.589 align:start position:0% much code actually it's kind of simple uh<00:07:44.720> we<00:07:44.879> are<00:07:45.039> going<00:07:45.319> to<00:07:45.560> go<00:07:45.800> through<00:07:46.000> it<00:07:46.280> in<00:07:46.400> a 00:07:46.589 --> 00:07:46.599 align:start position:0% uh we are going to go through it in a 00:07:46.599 --> 00:07:51.149 align:start position:0% uh we are going to go through it in a bit<00:07:47.440> but<00:07:47.879> uh<00:07:48.479> first<00:07:49.479> uh<00:07:49.879> let's<00:07:50.240> answer<00:07:50.879> this 00:07:51.149 --> 00:07:51.159 align:start position:0% bit but uh first uh let's answer this 00:07:51.159 --> 00:07:53.909 align:start position:0% bit but uh first uh let's answer this question<00:07:51.680> so<00:07:52.039> like<00:07:52.280> really<00:07:52.919> why<00:07:53.080> the<00:07:53.280> hell 00:07:53.909 --> 00:07:53.919 align:start position:0% question so like really why the hell 00:07:53.919 --> 00:07:55.390 align:start position:0% question so like really why the hell should<00:07:54.159> I<00:07:54.319> use 00:07:55.390 --> 00:07:55.400 align:start position:0% should I use 00:07:55.400 --> 00:07:58.029 align:start position:0% should I use half<00:07:56.400> uh<00:07:56.720> I<00:07:56.840> think<00:07:57.000> that's<00:07:57.159> an<00:07:57.400> honest 00:07:58.029 --> 00:07:58.039 align:start position:0% half uh I think that's an honest 00:07:58.039 --> 00:07:59.990 align:start position:0% half uh I think that's an honest question<00:07:59.039> and 00:07:59.990 --> 00:08:00.000 align:start position:0% question and 00:08:00.000 --> 00:08:02.790 align:start position:0% question and uh<00:08:00.360> yeah<00:08:00.520> let's<00:08:00.800> answer<00:08:01.199> this<00:08:01.400> question<00:08:02.039> so 00:08:02.790 --> 00:08:02.800 align:start position:0% uh yeah let's answer this question so 00:08:02.800 --> 00:08:06.230 align:start position:0% uh yeah let's answer this question so first<00:08:03.240> I<00:08:03.599> think<00:08:04.599> what's<00:08:05.199> really<00:08:05.720> nice<00:08:06.080> when 00:08:06.230 --> 00:08:06.240 align:start position:0% first I think what's really nice when 00:08:06.240 --> 00:08:07.710 align:start position:0% first I think what's really nice when you're<00:08:06.440> using<00:08:06.759> Huff<00:08:07.039> is<00:08:07.159> that<00:08:07.280> you<00:08:07.479> have 00:08:07.710 --> 00:08:07.720 align:start position:0% you're using Huff is that you have 00:08:07.720 --> 00:08:10.230 align:start position:0% you're using Huff is that you have access<00:08:08.080> to<00:08:08.520> like<00:08:08.720> all<00:08:08.879> the<00:08:09.039> up<00:08:09.319> codes<00:08:09.879> it's<00:08:10.039> not 00:08:10.230 --> 00:08:10.240 align:start position:0% access to like all the up codes it's not 00:08:10.240 --> 00:08:11.670 align:start position:0% access to like all the up codes it's not the<00:08:10.400> case<00:08:10.599> when<00:08:10.720> you're<00:08:10.879> using<00:08:11.199> inline 00:08:11.670 --> 00:08:11.680 align:start position:0% the case when you're using inline 00:08:11.680 --> 00:08:13.469 align:start position:0% the case when you're using inline assembly<00:08:12.400> even<00:08:12.639> if<00:08:12.759> you're<00:08:12.960> using<00:08:13.319> like 00:08:13.469 --> 00:08:13.479 align:start position:0% assembly even if you're using like

align:start position:0% Collins shared it on Twitter so I I just 00:08:47.519 --> 00:08:49.750 align:start position:0% Collins shared it on Twitter so I I just like<00:08:47.800> been<00:08:48.080> reusing<00:08:48.640> it<00:08:49.120> but<00:08:49.240> it<00:08:49.399> gives<00:08:49.560> you 00:08:49.750 --> 00:08:49.760 align:start position:0% like been reusing it but it gives you 00:08:49.760 --> 00:08:52.030 align:start position:0% like been reusing it but it gives you like<00:08:49.880> an<00:08:50.080> idea<00:08:50.399> like<00:08:50.600> this<00:08:50.720>

uh<00:08:54.920> contract<00:08:55.399> to<00:08:55.560> deploy<00:08:55.959> a 00:08:57.069 --> 00:08:57.079 align:start position:0% this uh contract to deploy a 00:08:57.079 --> 00:08:58.949 align:start position:0% this uh contract to deploy a contract<00:08:58.079> and<00:08:58.279> here<00:08:58.440> we're<00:08:58.640> just<00:08:58.839> like 00:08:58.949 --> 00:08:58.959 align:start position:0% contract and here we're just like 00:08:58.959 --> 00:09:02.509 align:start position:0% contract and here we're just like comparing<00:08:59.519> the<00:08:59.640> cost<00:08:59.920> to<00:09:00.839> read<00:09:01.160> and<00:09:01.480> write<00:09:02.279> uh 00:09:02.509 --> 00:09:02.519 align:start position:0% comparing the cost to read and write uh 00:09:02.519 --> 00:09:05.509 align:start position:0% comparing the cost to read and write uh like<00:09:03.000> um<00:09:04.000> read<00:09:04.200> and<00:09:04.440> write<00:09:04.720> operations<00:09:05.320> so 00:09:05.509 --> 00:09:05.519 align:start position:0% like um read and write operations so 00:09:05.519 --> 00:09:08.790 align:start position:0% like um read and write operations so using<00:09:05.959> half<00:09:06.320> Viper<00:09:07.040> solidity<00:09:07.720> Etc<00:09:08.320> so<00:09:08.600> it's 00:09:08.790 --> 00:09:08.800 align:start position:0% using half Viper solidity Etc so it's 00:09:08.800 --> 00:09:11.550 align:start position:0% using half Viper solidity Etc so it's not<00:09:09.519> exact<00:09:10.000> but<00:09:10.240> it<00:09:10.640> can<00:09:10.920>

obviously<00:09:15.440> there<00:09:15.560> are<00:09:15.760> some<00:09:16.000> stuff<00:09:16.320> that 00:09:16.470 --> 00:09:16.480 align:start position:0% code obviously there are some stuff that 00:09:16.480 --> 00:09:18.710 align:start position:0% code obviously there are some stuff that are<00:09:16.839> in<00:09:17.000> the<00:09:17.160> solidity<00:09:17.760> and<00:09:17.959>

align:start position:0% we don't have but yeah more freedom you 00:09:21.320 --> 00:09:22.870 align:start position:0% we don't have but yeah more freedom you can<00:09:21.480> do<00:09:21.640> whatever<00:09:22.000> you<00:09:22.120> want<00:09:22.360> if<00:09:22.480> you<00:09:22.560> want<00:09:22.720> to 00:09:22.870 --> 00:09:22.880 align:start position:0% can do whatever you want if

00:09:28.360 align:start position:0% it so you can make your Cod like more 00:09:28.360 --> 00:09:30.389 align:start position:0% it so you can make your Cod like more optimized 00:09:30.389 -->

was<00:10:11.320> like<00:10:11.440> a<00:10:11.760> crazy 00:10:12.829 --> 00:10:12.839 align:start position:0% that was like a crazy 00:10:12.839 --> 00:10:16.829 align:start position:0% that was like a crazy ID<00:10:13.839> uh<00:10:14.079> we<00:10:14.279> have<00:10:14.600> this<00:10:15.000> also<00:10:15.880> heridity<00:10:16.720> which 00:10:16.829 --> 00:10:16.839 align:start position:0% ID uh we have this also heridity which 00:10:16.839 --> 00:10:19.870 align:start position:0% ID uh we have this also heridity which is<00:10:17.040> like<00:10:17.160> a<00:10:17.320> way<00:10:17.519> to<00:10:17.720> run<00:10:18.680> uh<00:10:18.880> half<00:10:19.200> code<00:10:19.480> inside 00:10:19.870 --> 00:10:19.880 align:start position:0% is like a way to run uh half code inside 00:10:19.880 --> 00:10:23.550 align:start position:0% is like a way to run uh half code inside of<00:10:20.240> solidity<00:10:21.240> by<00:10:21.440> injecting<00:10:22.000> the<00:10:22.399> code<00:10:23.399> yeah 00:10:23.550 --> 00:10:23.560 align:start position:0% of solidity by injecting the code yeah 00:10:23.560 --> 00:10:26.310 align:start position:0% of solidity by injecting the code yeah it's<00:10:23.720> a<00:10:23.839> bit<00:10:24.399> isoteric<00:10:25.399> exotic<00:10:25.920> I<00:10:26.040> don't<00:10:26.160> know 00:10:26.310 --> 00:10:26.320 align:start position:0% it's a bit isoteric exotic I don't know 00:10:26.320 --> 00:10:28.630 align:start position:0% it's a bit isoteric exotic I don't know you<00:10:26.440> will<00:10:26.640> call<00:10:26.880> it<00:10:27.560> uh<00:10:27.760> the<00:10:27.880> way<00:10:28.040> you<00:10:28.160> want<00:10:28.480> but 00:10:28.630 --> 00:10:28.640 align:start position:0% you will call it uh the way you want but 00:10:28.640 --> 00:10:32.590 align:start position:0% you will call it uh the way you want but this<00:10:28.760> is<00:10:29.000> like<00:10:29.560> uh<00:10:29.959> at<00:10:30.120> the<00:10:30.240> boundary<00:10:30.720> of<00:10:31.240> uh<00:10:32.240> of 00:10:32.590 --> 00:10:32.600 align:start position:0% this is like uh at the boundary of uh of 00:10:32.600 --> 00:10:35.030 align:start position:0% this is like uh at the boundary of uh of the<00:10:32.959> the<00:10:33.480> what<00:10:33.680> what<00:10:33.839> we<00:10:33.959> can<00:10:34.160> do<00:10:34.480> and<00:10:34.800> maybe 00:10:35.030 --> 00:10:35.040 align:start position:0% the the what what we can do and maybe 00:10:35.040 --> 00:10:38.110 align:start position:0% the the what what we can do and maybe it's<00:10:35.200> not<00:10:35.399> a<00:10:35.519> good<00:10:35.760> idea<00:10:36.320> to<00:10:36.519> do<00:10:36.800> this<00:10:37.120> either 00:10:38.110 --> 00:10:38.120 align:start position:0% it's not a good idea to do this either 00:10:38.120 --> 00:10:40.710 align:start position:0% it's not a good idea to do this either but<00:10:38.560> I<00:10:38.639> think<00:10:38.880> like<00:10:39.079> the<00:10:39.279> best<00:10:39.920> uh<00:10:40.040> use<00:10:40.480> case 00:10:40.710 --> 00:10:40.720 align:start position:0% but I think like the best uh use case 00:10:40.720 --> 00:10:44.030 align:start position:0% but I think like the best uh use case for<00:10:41.639> uh<00:10:41.880> half<00:10:42.279> basically<00:10:42.959> just<00:10:43.160> to<00:10:43.519> teach<00:10:43.760> you 00:10:44.030 --> 00:10:44.040 align:start position:0% for uh half basically just to teach you 00:10:44.040 --> 00:10:47.069 align:start position:0% for uh half basically just to teach you how<00:10:44.320> the<00:10:44.480> evm<00:10:44.959> works<00:10:45.600> so<00:10:45.760> you<00:10:45.920> can<00:10:46.120> become<00:10:46.560> the 00:10:47.069 --> 00:10:47.079 align:start position:0% how the evm works so you can become the 00:10:47.079 --> 00:10:48.269 align:start position:0% how the evm works so you can become the evm 00:10:48.269 --> 00:10:48.279 align:start position:0% evm 00:10:48.279 --> 00:10:51.230 align:start position:0% evm Chad<00:10:49.279> um<00:10:49.800> yeah<00:10:50.000> because<00:10:50.480> what<00:10:50.680> we<00:10:50.920> have<00:10:51.079> been 00:10:51.230 --> 00:10:51.240 align:start position:0% Chad um yeah because what we have been 00:10:51.240 --> 00:10:54.750 align:start position:0% Chad um yeah because what we have been seeing<00:10:51.800> that<00:10:52.639> uh<00:10:52.800> since<00:10:53.200> half<00:10:53.519> has<00:10:53.760> been 00:10:54.750 --> 00:10:54.760 align:start position:0% seeing that uh since half has been 00:10:54.760 --> 00:10:58.069 align:start position:0% seeing that uh since half has been created<00:10:55.560> or<00:10:56.560> revived<00:10:57.240> we<00:10:57.360> can<00:10:57.519> say<00:10:57.680> it<00:10:57.880> this 00:10:58.069 --> 00:10:58.079 align:start position:0% created or revived we can say it this 00:10:58.079 --> 00:11:00.990 align:start position:0% created or revived we can say it this way<00:10:58.560> many<00:10:58.839> people<00:10:59.360> like<00:10:59.560> me<00:11:00.200> got<00:11:00.519> interested 00:11:00.990 --> 00:11:01.000 align:start position:0% way many people like me got interested 00:11:01.000 --> 00:11:03.910 align:start position:0% way many people like me got interested into<00:11:01.440> have<00:11:01.920> and<00:11:02.399> we<00:11:02.560> can<00:11:02.720> learn<00:11:03.040> a<00:11:03.200> lot<00:11:03.480> about 00:11:03.910 --> 00:11:03.920 align:start position:0% into have and we can learn a lot about 00:11:03.920 --> 00:11:05.949 align:start position:0% into have and we can learn a lot about the<00:11:04.079> evm<00:11:04.920> and<00:11:05.040> then<00:11:05.160> we<00:11:05.279> can<00:11:05.480> get<00:11:05.680> more 00:11:05.949 --> 00:11:05.959 align:start position:0% the evm and then we can get more 00:11:05.959 --> 00:11:07.710 align:start position:0% the evm and then we can get more familiar<00:11:06.480> with<00:11:06.600> it<00:11:06.839> and<00:11:07.000> just<00:11:07.279> become<00:11:07.560> a 00:11:07.710 --> 00:11:07.720 align:start position:0% familiar with it and just become a 00:11:07.720 --> 00:11:09.509 align:start position:0% familiar with it and just become a better<00:11:08.040> developer<00:11:08.760> so<00:11:08.959> when<00:11:09.079> you<00:11:09.160> will<00:11:09.360> be 00:11:09.509 --> 00:11:09.519 align:start position:0% better developer so when you will be 00:11:09.519 --> 00:11:11.910 align:start position:0% better developer so when you will be writing<00:11:09.880> solidity<00:11:10.480> code<00:11:10.959> you<00:11:11.120> know<00:11:11.399> exactly 00:11:11.910 --> 00:11:11.920 align:start position:0% writing solidity code you know exactly 00:11:11.920 --> 00:11:14.550 align:start position:0% writing solidity code you know exactly like<00:11:12.200> what<00:11:12.360> the<00:11:12.519> code<00:11:12.839> is<00:11:13.040> doing<00:11:14.040> uh<00:11:14.160> you<00:11:14.279> can 00:11:14.550 --> 00:11:14.560 align:start position:0% like what the code is doing uh you can 00:11:14.560 --> 00:11:17.269 align:start position:0% like what the code is doing uh you can maybe<00:11:14.839> write<00:11:15.079> some<00:11:15.440> optimizations<00:11:16.440> in<00:11:16.800> inline 00:11:17.269 --> 00:11:17.279 align:start position:0% maybe write some optimizations in inline 00:11:17.279 --> 00:11:19.030 align:start position:0% maybe write some optimizations in inline assembly<00:11:18.040> or<00:11:18.160> if<00:11:18.279> you're<00:11:18.480> debugging 00:11:19.030 --> 00:11:19.040 align:start position:0% assembly or if you're debugging 00:11:19.040 --> 00:11:20.670 align:start position:0% assembly or if you're debugging something<00:11:19.639> so<00:11:19.839> it<00:11:19.920> will<00:11:20.120> give<00:11:20.240> you<00:11:20.399> like<00:11:20.519> a 00:11:20.670 --> 00:11:20.680 align:start position:0% something so it will give you like a 00:11:20.680 --> 00:11:23.389 align:start position:0% something so it will give you like a better<00:11:21.360> understanding<00:11:22.079> of<00:11:22.360> like<00:11:22.600> how<00:11:22.800> the<00:11:22.920> evm 00:11:23.389 --> 00:11:23.399 align:start position:0% better understanding of like how the evm 00:11:23.399 --> 00:11:28.030 align:start position:0% better understanding of like how the evm works<00:11:23.839> how<00:11:24.040> under<00:11:24.360> the<00:11:24.560> hood<00:11:25.360> everything<00:11:25.760> is 00:11:28.030 --> 00:11:28.040 align:start position:0% 00:11:28.040 --> 00:11:31.150 align:start position:0% happening<00:11:29.040> and<00:11:29.360> and<00:11:29.600> yeah<00:11:29.800> like<00:11:29.920> today<00:11:30.920> uh<00:11:31.120> I 00:11:31.150 --> 00:11:31.160 align:start position:0% happening and and yeah like today uh I 00:11:31.160 --> 00:11:32.670 align:start position:0% happening and and yeah like today uh I mean<00:11:31.360> it's<00:11:31.519> been<00:11:31.680> a<00:11:31.839> while<00:11:32.079> already<00:11:32.440> but<00:11:32.600> I 00:11:32.670 --> 00:11:32.680 align:start position:0% mean it's been a while already but I 00:11:32.680 --> 00:11:35.470 align:start position:0% mean it's been a while already but I mean<00:11:32.880> like<00:11:33.560> nowadays<00:11:34.560> there<00:11:34.680> are<00:11:34.839> many<00:11:35.079> tools 00:11:35.470 --> 00:11:35.480 align:start position:0% mean like nowadays there are many tools 00:11:35.480 --> 00:11:36.870 align:start position:0% mean like nowadays there are many tools like<00:11:35.639> for<00:11:35.800> example<00:11:36.160> if<00:11:36.279> you<00:11:36.360> want<00:11:36.519> to<00:11:36.639> write 00:11:36.870 --> 00:11:36.880 align:start position:0% like for example if you want to write 00:11:36.880 --> 00:11:40.269 align:start position:0% like for example if you want to write some<00:11:37.160> Huff<00:11:38.160> uh<00:11:38.320> you<00:11:38.440> can<00:11:38.600> use<00:11:38.880> like<00:11:39.120> Foundry<00:11:40.120> uh 00:11:40.269 --> 00:11:40.279 align:start position:0% some Huff uh you can use like Foundry uh 00:11:40.279 --> 00:11:42.470 align:start position:0% some Huff uh you can use like Foundry uh to<00:11:40.560> test<00:11:40.800> your<00:11:41.040> contract<00:11:41.560> so<00:11:41.880> it's<00:11:42.120> it's 00:11:42.470 --> 00:11:42.480 align:start position:0% to test your contract so it's it's 00:11:42.480 --> 00:11:44.990 align:start position:0% to test your contract so it's it's extremely<00:11:43.000> simple<00:11:43.800> there's<00:11:44.040> a<00:11:44.200> template<00:11:44.600> for 00:11:44.990 --> 00:11:45.000 align:start position:0% extremely simple there's a template for 00:11:45.000 --> 00:11:47.430 align:start position:0% extremely simple there's a template for that<00:11:46.000> and<00:11:46.200> then<00:11:46.600> there<00:11:46.720> are<00:11:46.920> also<00:11:47.240> like 00:11:47.430 --> 00:11:47.440 align:start position:0% that and then there are also like 00:11:47.440 --> 00:11:50.509 align:start position:0% that and then there are also like libraries<00:11:47.920> like<00:11:48.120> hmates<00:11:49.000> so<00:11:49.200> if<00:11:49.320> you<00:11:49.440> want<00:11:49.680> to 00:11:50.509 --> 00:11:50.519 align:start position:0% libraries like hmates so if you want to 00:11:50.519 --> 00:11:52.030 align:start position:0% libraries like hmates so if you want to write<00:11:50.839> something<00:11:51.360> then<00:11:51.560> I<00:11:51.680> don't<00:11:51.760> know<00:11:51.920> like 00:11:52.030 --> 00:11:52.040 align:start position:0% write something then I don't know like 00:11:52.040 --> 00:11:54.150 align:start position:0% write something then I don't know like an<00:11:52.160> erc20<00:11:53.040> there<00:11:53.160> are<00:11:53.519> already<00:11:53.880> like<00:11:54.000> a 00:11:54.150 --> 00:11:54.160 align:start position:0% an erc20 there are already like a 00:11:54.160 --> 00:11:56.790 align:start position:0% an erc20 there are already like a template<00:11:54.600> that<00:11:54.760> was<00:11:54.959> made<00:11:55.880> uh<00:11:56.079> but<00:11:56.360> I<00:11:56.480> think 00:11:56.790 --> 00:11:56.800 align:start position:0% template that was made uh but I think 00:11:56.800 --> 00:11:59.030 align:start position:0% template that was made uh but I think like<00:11:57.000> the<00:11:57.160> best<00:11:57.639> use<00:11:58.040> case<00:11:58.200> for<00:11:58.399> this<00:11:58.600> library 00:11:59.030 --> 00:11:59.040 align:start position:0% like the best use case for this library 00:11:59.040 --> 00:12:00.870 align:start position:0% like the best use case for this library is<00:11:59.240> is<00:11:59.399> to<00:12:00.000> just<00:12:00.200> go<00:12:00.360> through<00:12:00.560> all<00:12:00.720> the 00:12:00.870 --> 00:12:00.880 align:start position:0% is is to just go through all the 00:12:00.880 --> 00:12:02.990 align:start position:0% is is to just go through all the contracts<00:12:01.440> and<00:12:01.600> try<00:12:01.800> to<00:12:02.320> understand<00:12:02.560> how<00:12:02.760> they 00:12:02.990 --> 00:12:03.000 align:start position:0% contracts and try to understand how they 00:12:03.000 --> 00:12:06.750 align:start position:0% contracts and try to understand how they work<00:12:04.000> I<00:12:04.120> think<00:12:04.279> it's<00:12:04.560> like<00:12:05.120> maybe<00:12:05.480> has<00:12:05.760> like<00:12:06.079> uh 00:12:06.750 --> 00:12:06.760 align:start position:0% work I think it's like maybe has like uh 00:12:06.760 --> 00:12:10.069 align:start position:0% work I think it's like maybe has like uh all<00:12:07.000> the<00:12:07.480> same<00:12:07.760> contract<00:12:08.240> as<00:12:08.800> soulmate<00:12:09.800> maybe 00:12:10.069 --> 00:12:10.079 align:start position:0% all the same contract as soulmate maybe 00:12:10.079 --> 00:12:12.990 align:start position:0% all the same contract as soulmate maybe I'm<00:12:10.240> not<00:12:10.360> sure<00:12:10.639> but<00:12:11.240> many<00:12:11.560> stuff<00:12:11.920> like<00:12:12.279> ownable 00:12:12.990 --> 00:12:13.000 align:start position:0% I'm not sure but many stuff like ownable 00:12:13.000 --> 00:12:16.430 align:start position:0% I'm not sure but many stuff like ownable like<00:12:13.519> many<00:12:14.519> create<00:12:14.880> three<00:12:15.480> libraries<00:12:16.199> stuff 00:12:16.430 --> 00:12:16.440 align:start position:0% like many create three libraries stuff 00:12:16.440 --> 00:12:20.110 align:start position:0% like many create three libraries stuff like<00:12:16.639> that<00:12:16.760> so<00:12:17.160> it's<00:12:17.480> very<00:12:17.720> impressive 00:12:20.110 --> 00:12:20.120 align:start position:0% like that so it's very impressive 00:12:20.120 --> 00:12:24.550 align:start position:0% like that so it's very impressive also<00:12:21.160> so<00:12:22.160> yeah<00:12:22.639> I<00:12:22.760> think<00:12:23.199> now<00:12:23.920> it's<00:12:24.160> time<00:12:24.440> I 00:12:24.550 --> 00:12:24.560 align:start position:0% also so yeah I think now it's time I 00:12:24.560 --> 00:12:26.910 align:start position:0% also so yeah I think now it's time I made<00:12:24.800> like<00:12:24.920> a<00:12:25.240> small<00:12:25.600> introduction<00:12:26.560> so<00:12:26.800> I 00:12:26.910 --> 00:12:26.920 align:start position:0% made like a small introduction so I 00:12:26.920 --> 00:12:30.110 align:start position:0% made like a small introduction so I think<00:12:27.120> now<00:12:27.320> it's<00:12:27.560> time<00:12:27.760> to<00:12:28.440> maybe<00:12:28.760> start<00:12:29.440> going 00:12:30.110 --> 00:12:30.120 align:start position:0% think now it's time to maybe start going 00:12:30.120 --> 00:12:32.230 align:start position:0% think now it's time to maybe start going deeper<00:12:30.480> into 00:12:32.230 --> 00:12:32.240 align:start position:0% deeper into 00:12:32.240 --> 00:12:34.590 align:start position:0% deeper into half<00:12:33.240> so<00:12:33.480> I<00:12:33.600> think<00:12:33.720> we're<00:12:33.959> going<00:12:34.120> to<00:12:34.240> do<00:12:34.440> this 00:12:34.590 --> 00:12:34.600 align:start position:0% half so I think we're going to do this 00:12:34.600 --> 00:12:37.150 align:start position:0% half so I think we're going to do this in<00:12:35.120> two<00:12:35.440> parts<00:12:35.880> actually<00:12:36.560> first<00:12:36.800> I'm<00:12:36.959> just 00:12:37.150 --> 00:12:37.160 align:start position:0% in two parts actually first I'm just 00:12:37.160 --> 00:12:38.470 align:start position:0% in two parts actually first I'm just going<00:12:37.360> to<00:12:37.519> go<00:12:37.680> through<00:12:37.880> like<00:12:38.079> all<00:12:38.240> the 00:12:38.470 --> 00:12:38.480 align:start position:0% going to go through like all the 00:12:38.480 --> 00:12:40.910 align:start position:0% going to go through like all the features<00:12:39.079> that<00:12:39.240> we<00:12:39.440> have<00:12:39.639> in<00:12:39.800> Rust<00:12:40.519> so<00:12:40.760> you 00:12:40.910 --> 00:12:40.920 align:start position:0% features that we have in Rust so you 00:12:40.920 --> 00:12:43.910 align:start position:0% features that we have in Rust so you guys<00:12:41.120> can<00:12:41.320> get<00:12:41.560> like<00:12:41.720> a<00:12:42.000> more<00:12:43.000> uh<00:12:43.680> like<00:12:43.800> a 00:12:43.910 --> 00:12:43.920 align:start position:0% guys can get like a more uh like a 00:12:43.920 --> 00:12:46.350 align:start position:0% guys can get like a more uh like a better<00:12:44.560> understanding<00:12:44.839> of<00:12:45.279> what<00:12:45.440> we<00:12:45.560> can<00:12:45.760> do 00:12:46.350 --> 00:12:46.360 align:start position:0% better understanding of what we can do 00:12:46.360 --> 00:12:49.790 align:start position:0% better understanding of what we can do and<00:12:47.360> how<00:12:47.560> we<00:12:47.680> can<00:12:47.920> do<00:12:48.160> it<00:12:48.959> and<00:12:49.160> then<00:12:49.320> we'll<00:12:49.600> get 00:12:49.790 --> 00:12:49.800 align:start position:0% and how we can do it and then we'll get 00:12:49.800 --> 00:12:53.590 align:start position:0% and how we can do it and then we'll get to<00:12:50.040> write<00:12:50.279> some<00:12:50.720> actual<00:12:51.440> code<00:12:52.440> so<00:12:53.000> yeah<00:12:53.279> as<00:12:53.399> I 00:12:53.590 --> 00:12:53.600 align:start position:0% to write some actual code so yeah as I 00:12:53.600 --> 00:12:56.230 align:start position:0% to write some actual code so yeah as I said<00:12:53.920> basically<00:12:54.440> like<00:12:54.800> half<00:12:55.120> is<00:12:55.360> like<00:12:55.959> some 00:12:56.230 --> 00:12:56.240 align:start position:0% said basically like half is like some 00:12:56.240 --> 00:12:58.750 align:start position:0% said basically like half is like some kind<00:12:56.440> of<00:12:57.160> Assembly<00:12:57.680> Language<00:12:58.199> with<00:12:58.440> many 00:12:58.750 --> 00:12:58.760 align:start position:0% kind of Assembly Language with many 00:12:58.760 --> 00:13:00.030 align:start position:0% kind of Assembly Language with many convenience 00:13:00.030 --> 00:13:00.040 align:start position:0% convenience 00:13:00.040 --> 00:13:01.590 align:start position:0% convenience features 00:13:01.590 --> 00:13:01.600 align:start position:0% features 00:13:01.600 --> 00:13:04.430 align:start position:0% features and<00:13:02.600> yeah<00:13:03.000> first<00:13:03.360> I'm<00:13:03.600> just<00:13:03.760> going<00:13:03.959> to<00:13:04.199> go 00:13:04.430 --> 00:13:04.440 align:start position:0% and yeah first I'm just going to go 00:13:04.440 --> 00:13:07.150 align:start position:0% and yeah first I'm just going to go through<00:13:04.880> like<00:13:05.480> how<00:13:05.720> the<00:13:05.880> evm<00:13:06.360> works<00:13:06.800> I'm<00:13:06.880> sure 00:13:07.150 --> 00:13:07.160 align:start position:0% through like how the evm works I'm sure 00:13:07.160 --> 00:13:08.910 align:start position:0% through like how the evm works I'm sure like<00:13:07.360> all<00:13:07.480> of<00:13:07.600> you<00:13:07.800> know<00:13:08.160> but<00:13:08.320> maybe<00:13:08.639> there's 00:13:08.910 --> 00:13:08.920 align:start position:0% like all of you know but maybe there's 00:13:08.920 --> 00:13:11.430 align:start position:0% like all of you know but maybe there's like<00:13:09.480> one<00:13:09.800> two<00:13:10.040> people<00:13:10.399> that<00:13:10.600> are<00:13:10.839> not<00:13:11.079> very 00:13:11.430 --> 00:13:11.440 align:start position:0% like one two people that are not very 00:13:11.440 --> 00:13:14.710 align:start position:0% like one two people that are not very familiar<00:13:11.959> with<00:13:12.079> it<00:13:12.279> so<00:13:12.680> I<00:13:12.760> just<00:13:12.920> want<00:13:13.360> to<00:13:14.360> um<00:13:14.560> be 00:13:14.710 --> 00:13:14.720 align:start position:0% familiar with it so I just want to um be 00:13:14.720 --> 00:13:16.750 align:start position:0% familiar with it so I just want to um be sure<00:13:14.959> that<00:13:15.160> we<00:13:15.240> are<00:13:15.360> all<00:13:15.519> on<00:13:15.639> the<00:13:15.800> same<00:13:16.040> page<00:13:16.519> so 00:13:16.750 --> 00:13:16.760 align:start position:0% sure that we are all on the same page so 00:13:16.760 --> 00:13:18.710 align:start position:0% sure that we are all on the same page so this<00:13:16.839> is<00:13:16.959> a<00:13:17.199> stack<00:13:17.839> this<00:13:17.959> is 00:13:18.710 --> 00:13:18.720 align:start position:0% this is a stack this is 00:13:18.720 --> 00:13:22.829 align:start position:0% this is a stack this is where<00:13:19.720> uh<00:13:19.920> most<00:13:20.120> of<00:13:20.320> the<00:13:21.480> manipulations<00:13:22.480> or 00:13:22.829 --> 00:13:22.839 align:start position:0% where uh most of the manipulations or 00:13:22.839 --> 00:13:25.389 align:start position:0% where uh most of the manipulations or handle<00:13:23.399> like<00:13:23.560> if<00:13:23.680> you<00:13:23.800> want<00:13:24.000> to<00:13:24.880> uh<00:13:25.000> store 00:13:25.389 --> 00:13:25.399 align:start position:0% handle like if you want to uh store 00:13:25.399 --> 00:13:27.790 align:start position:0% handle like if you want to uh store values<00:13:25.839> if<00:13:25.959> you<00:13:26.079> want<00:13:26.240> to<00:13:26.440> compute<00:13:26.839> stuff<00:13:27.199> like 00:13:27.790 --> 00:13:27.800 align:start position:0% values if you want to compute stuff like 00:13:27.800 --> 00:13:29.790 align:start position:0% values if you want to compute stuff like everything<00:13:28.160> will<00:13:28.519> be<00:13:28.720> happening<00:13:29.360> into<00:13:29.639> the 00:13:29.790 --> 00:13:29.800 align:start position:0% everything will be happening into the 00:13:29.800 --> 00:13:32.230 align:start position:0% everything will be happening into the stack<00:13:30.360> so<00:13:30.639> the<00:13:30.760> way<00:13:30.880> it<00:13:31.000> works<00:13:31.240> is<00:13:31.440> very<00:13:31.680> simple 00:13:32.230 --> 00:13:32.240 align:start position:0% stack so the way it works is very simple 00:13:32.240 --> 00:13:34.310 align:start position:0% stack so the way it works is very simple you<00:13:32.440> have<00:13:32.680> here<00:13:32.920> like<00:13:33.240> a<00:13:33.440> pile<00:13:33.800> you're<00:13:34.079> just 00:13:34.310 --> 00:13:34.320 align:start position:0% you have here like a pile you're just 00:13:34.320 --> 00:13:36.949 align:start position:0% you have here like a pile you're just like<00:13:34.440> stacking<00:13:34.959> values<00:13:35.760> from<00:13:36.079> like<00:13:36.519> uh<00:13:36.760> the 00:13:36.949 --> 00:13:36.959 align:start position:0% like stacking values from like uh the 00:13:36.959 --> 00:13:39.069 align:start position:0% like stacking values from like uh the top<00:13:37.519> the<00:13:37.720> bottom<00:13:38.040> to<00:13:38.199> the<00:13:38.360> to<00:13:38.519> the<00:13:38.639> top<00:13:38.839> so 00:13:39.069 --> 00:13:39.079 align:start position:0% top the bottom to the to the top so 00:13:39.079 --> 00:13:41.430 align:start position:0% top the bottom to the to the top so you're<00:13:39.320> just<00:13:39.560> like<00:13:39.959> adding<00:13:40.279> new<00:13:40.560> values<00:13:41.120> on 00:13:41.430 --> 00:13:41.440 align:start position:0% you're just like adding new values on 00:13:41.440 --> 00:13:43.790 align:start position:0% you're just like adding new values on top<00:13:42.440> if<00:13:42.519> you<00:13:42.639> want<00:13:42.800> to<00:13:42.959> remove<00:13:43.279> a<00:13:43.440> value<00:13:43.720> you 00:13:43.790 --> 00:13:43.800 align:start position:0% top if you want to remove a value you 00:13:43.800 --> 00:13:46.069 align:start position:0% top if you want to remove a value you will<00:13:44.040> pop<00:13:44.680> the<00:13:44.839> last<00:13:45.160> value<00:13:45.440> that<00:13:45.560> you<00:13:45.760> just 00:13:46.069 --> 00:13:46.079 align:start position:0% will pop the last value that you just 00:13:46.079 --> 00:13:48.790 align:start position:0% will pop the last value that you just added<00:13:47.079> and<00:13:47.360> what<00:13:47.519> is<00:13:47.680> going<00:13:47.839> to<00:13:48.079> happen<00:13:48.600> is 00:13:48.790 --> 00:13:48.800 align:start position:0% added and what is going to happen is 00:13:48.800 --> 00:13:52.430 align:start position:0% added and what is going to happen is that<00:13:49.360> let's<00:13:49.560> say<00:13:49.760> we<00:13:49.920> have<00:13:50.120> like<00:13:50.320> a<00:13:50.519> b<00:13:51.160> c<00:13:51.440> and<00:13:51.680> d 00:13:52.430 --> 00:13:52.440 align:start position:0% that let's say we have like a b c and d 00:13:52.440 --> 00:13:54.509 align:start position:0% that let's say we have like a b c and d and<00:13:52.720> then<00:13:52.839> you<00:13:52.959> want<00:13:53.199> to<00:13:53.440> multiply<00:13:54.120> something 00:13:54.509 --> 00:13:54.519 align:start position:0% and then you want to multiply something 00:13:54.519 --> 00:13:57.430 align:start position:0% and then you want to multiply something so<00:13:54.720> you're<00:13:54.959> going<00:13:55.120> to<00:13:55.279> use<00:13:55.560> the<00:13:56.079> multiply<00:13:57.079> up 00:13:57.430 --> 00:13:57.440 align:start position:0% so you're going to use the multiply up 00:13:57.440 --> 00:13:59.430 align:start position:0% so you're going to use the multiply up code<00:13:58.079> then<00:13:58.279> what<00:13:58.360> is<00:13:58.519> going<00:13:58.680> to<00:13:58.800> happen<00:13:59.320> that 00:13:59.430 --> 00:13:59.440 align:start position:0% code then what is going to happen that 00:13:59.440 --> 00:14:01.350 align:start position:0% code then what is going to happen that the<00:13:59.560> evm<00:14:00.000> is<00:14:00.120> just<00:14:00.320> going<00:14:00.480> to<00:14:00.680> take<00:14:00.920> like<00:14:01.120> the 00:14:01.350 --> 00:14:01.360 align:start position:0% the evm is just going to take like the 00:14:01.360 --> 00:14:04.629 align:start position:0% the evm is just going to take like the two<00:14:01.920> latest<00:14:02.519> values<00:14:03.279> and<00:14:03.600> it<00:14:03.720> will<00:14:04.000> multiply 00:14:04.629 --> 00:14:04.639 align:start position:0% two latest values and it will multiply 00:14:04.639 --> 00:14:06.590 align:start position:0% two latest values and it will multiply them<00:14:05.000> and<00:14:05.199> it's<00:14:05.399> going<00:14:05.600> to<00:14:05.839> put<00:14:06.040> them<00:14:06.279> back 00:14:06.590 --> 00:14:06.600 align:start position:0% them and it's going to put them back 00:14:06.600 --> 00:14:09.509 align:start position:0% them and it's going to put them back into<00:14:07.360> the<00:14:07.600> the 00:14:09.509 --> 00:14:09.519 align:start position:0% into the the 00:14:09.519 --> 00:14:12.509 align:start position:0% into the the stack<00:14:10.519> uh<00:14:10.720> yeah<00:14:10.920> this<00:14:11.040> is<00:14:11.240> just<00:14:11.480> like<00:14:12.040> another 00:14:12.509 --> 00:14:12.519 align:start position:0% stack uh yeah this is just like another 00:14:12.519 --> 00:14:14.389 align:start position:0% stack uh yeah this is just like another representation<00:14:13.160> of<00:14:13.360> the<00:14:13.519> stack<00:14:13.800> so<00:14:14.040> still<00:14:14.240> the 00:14:14.389 --> 00:14:14.399 align:start position:0% representation of the stack so still the 00:14:14.399 --> 00:14:17.550 align:start position:0% representation of the stack so still the same<00:14:14.639> thing<00:14:15.600> um<00:14:16.079> just<00:14:16.320> be<00:14:16.480> aware<00:14:16.839> we<00:14:17.000> have<00:14:17.240> like 00:14:17.550 --> 00:14:17.560 align:start position:0% same thing um just be aware we have like 00:14:17.560 --> 00:14:20.030 align:start position:0% same thing um just be aware we have like a<00:14:18.000> plenty<00:14:18.320> of<00:14:18.519> space<00:14:18.880> like 00:14:20.030 --> 00:14:20.040 align:start position:0% a plenty of space like 00:14:20.040 --> 00:14:23.389 align:start position:0% a plenty of space like 1,24<00:14:21.040> values<00:14:21.839> uh<00:14:22.000> the<00:14:22.120> thing<00:14:22.279> is<00:14:22.440> that<00:14:22.680> we<00:14:23.120> can 00:14:23.389 --> 00:14:23.399 align:start position:0% 1,24 values uh the thing is that we can 00:14:23.399 --> 00:14:26.269 align:start position:0% 1,24 values uh the thing is that we can only<00:14:23.800> get<00:14:24.079> like<00:14:24.240> the<00:14:24.519> three<00:14:25.519> uh<00:14:25.639> two<00:14:25.959> first 00:14:26.269 --> 00:14:26.279 align:start position:0% only get like the three uh two first 00:14:26.279 --> 00:14:28.590 align:start position:0% only get like the three uh two first values<00:14:26.720> because<00:14:27.360> we<00:14:27.560> have<00:14:27.800> only<00:14:28.120> like<00:14:28.320> up 00:14:28.590 --> 00:14:28.600 align:start position:0% values because we have only like up 00:14:28.600 --> 00:14:29.670 align:start position:0% values because we have only like up codes 00:14:29.670 --> 00:14:29.680 align:start position:0% codes 00:14:29.680 --> 00:14:32.189 align:start position:0% codes for<00:14:29.959> now<00:14:30.199> we<00:14:30.320> only<00:14:30.560> have<00:14:30.800> up<00:14:31.079> codes<00:14:31.360> to<00:14:31.759> get 00:14:32.189 --> 00:14:32.199 align:start position:0% for now we only have up codes to get 00:14:32.199 --> 00:14:35.590 align:start position:0% for now we only have up codes to get value<00:14:32.720> up<00:14:32.880> to<00:14:33.120> the<00:14:33.360> 30<00:14:34.199> uh<00:14:34.360> second<00:14:34.759> value<00:14:35.480> this 00:14:35.590 --> 00:14:35.600 align:start position:0% value up to the 30 uh second value this 00:14:35.600 --> 00:14:37.470 align:start position:0% value up to the 30 uh second value this will<00:14:35.800> change<00:14:36.120> maybe<00:14:36.399> with<00:14:36.560> the<00:14:36.680> eof<00:14:37.199> but<00:14:37.320> for 00:14:37.470 --> 00:14:37.480 align:start position:0% will change maybe with the eof but for 00:14:37.480 --> 00:14:41.030 align:start position:0% will change maybe with the eof but for now<00:14:37.759> this<00:14:37.880> is<00:14:38.040> the<00:14:38.199> way<00:14:38.680> things<00:14:39.120> Works<00:14:40.120> um<00:14:40.880> and 00:14:41.030 --> 00:14:41.040 align:start position:0% now this is the way things Works um and 00:14:41.040 --> 00:14:42.870 align:start position:0% now this is the way things Works um and this<00:14:41.160> is<00:14:41.360> why<00:14:41.480> we<00:14:41.639> have<00:14:41.880> like<00:14:42.040> a<00:14:42.320> stack<00:14:42.680> too 00:14:42.870 --> 00:14:42.880 align:start position:0% this is why we have like a stack too 00:14:42.880 --> 00:14:46.790 align:start position:0% this is why we have like a stack too deep<00:14:43.079> in<00:14:43.240> solidity<00:14:44.279> also<00:14:45.279> um<00:14:46.279> then<00:14:46.480> we<00:14:46.600> have 00:14:46.790 --> 00:14:46.800 align:start position:0% deep in solidity also um then we have 00:14:46.800 --> 00:14:50.749 align:start position:0% deep in solidity also um then we have the<00:14:47.000> memory<00:14:47.560> which<00:14:47.720> is<00:14:47.880> like<00:14:48.199> another<00:14:48.920> area<00:14:49.759> to 00:14:50.749 --> 00:14:50.759 align:start position:0% the memory which is like another area to 00:14:50.759 --> 00:14:52.790 align:start position:0% the memory which is like another area to save<00:14:51.120> some<00:14:51.399> values<00:14:51.920> the<00:14:52.040> memory<00:14:52.399> is<00:14:52.600> very 00:14:52.790 --> 00:14:52.800 align:start position:0% save some values the memory is very 00:14:52.800 --> 00:14:55.509 align:start position:0% save some values the memory is very simple<00:14:53.240> you<00:14:53.399> have<00:14:53.639> like<00:14:54.160> an<00:14:54.440> address<00:14:54.959> and 00:14:55.509 --> 00:14:55.519 align:start position:0% simple you have like an address and 00:14:55.519 --> 00:14:57.870 align:start position:0% simple you have like an address and value<00:14:56.519> addresses<00:14:57.079> and<00:14:57.279> values<00:14:57.600> they<00:14:57.720> are 00:14:57.870 --> 00:14:57.880 align:start position:0% value addresses and values they are 00:14:57.880 --> 00:15:00.310 align:start position:0% value addresses and values they are using<00:14:58.199> like<00:14:58.360> 32<00:14:58.839> Byes<00:14:59.440> so<00:14:59.639> basically<00:15:00.040> you<00:15:00.160> can 00:15:00.310 --> 00:15:00.320 align:start position:0% using like 32 Byes so basically you can 00:15:00.320 --> 00:15:04.150 align:start position:0% using like 32 Byes so basically you can just<00:15:00.560> store<00:15:01.560> whatever<00:15:01.959> you<00:15:02.360> want<00:15:03.360> uh<00:15:03.800> wherever 00:15:04.150 --> 00:15:04.160 align:start position:0% just store whatever you want uh wherever 00:15:04.160 --> 00:15:06.749 align:start position:0% just store whatever you want uh wherever you<00:15:04.320> want<00:15:04.800> just<00:15:05.040> have<00:15:05.199> to<00:15:05.800> follow<00:15:06.279> the<00:15:06.480> this 00:15:06.749 --> 00:15:06.759 align:start position:0% you want just have to follow the this 00:15:06.759 --> 00:15:09.710 align:start position:0% you want just have to follow the this pattern<00:15:07.759> uh<00:15:07.920> the<00:15:08.079> storage<00:15:08.560> is<00:15:08.720> following<00:15:09.279> the 00:15:09.710 --> 00:15:09.720 align:start position:0% pattern uh the storage is following the 00:15:09.720 --> 00:15:12.670 align:start position:0% pattern uh the storage is following the same<00:15:10.720> um<00:15:11.279> pattern<00:15:11.839> and<00:15:12.000> we<00:15:12.160> also<00:15:12.399> have<00:15:12.560> the 00:15:12.670 --> 00:15:12.680 align:start position:0% same um pattern and we also have the 00:15:12.680 --> 00:15:15.189 align:start position:0% same um pattern and we also have the tring<00:15:13.000> in<00:15:13.279> storage<00:15:13.839> which<00:15:13.959> is<00:15:14.199> also<00:15:14.560> the<00:15:15.000> more 00:15:15.189 --> 00:15:15.199 align:start position:0% tring in storage which is also the more 00:15:15.199 --> 00:15:17.749 align:start position:0% tring in storage which is also the more less<00:15:15.519> the<00:15:15.639> same 00:15:17.749 --> 00:15:17.759 align:start position:0% less the same 00:15:17.759 --> 00:15:20.509 align:start position:0% less the same thing<00:15:18.759> uh<00:15:18.920> and<00:15:19.079> this<00:15:19.160> is<00:15:19.279> the<00:15:19.480> call<00:15:19.800> data<00:15:20.279> so 00:15:20.509 --> 00:15:20.519 align:start position:0% thing uh and this is the call data so 00:15:20.519 --> 00:15:23.350 align:start position:0% thing uh and this is the call data so call<00:15:20.880> data<00:15:21.320> when<00:15:21.639> we<00:15:21.759> are<00:15:21.959> referring<00:15:22.399> to<00:15:22.680> to<00:15:22.880> it 00:15:23.350 --> 00:15:23.360 align:start position:0% call data when we are referring to to it 00:15:23.360 --> 00:15:26.110 align:start position:0% call data when we are referring to to it is<00:15:23.560> just<00:15:23.800> like<00:15:23.959> a<00:15:24.240> value<00:15:24.639> that<00:15:25.320> uh<00:15:25.480> someone<00:15:25.959> is 00:15:26.110 --> 00:15:26.120 align:start position:0% is just like a value that uh someone is 00:15:26.120 --> 00:15:27.790 align:start position:0% is just like a value that uh someone is passing<00:15:26.480> to<00:15:26.680> your<00:15:26.959> contract<00:15:27.440> when<00:15:27.560> they're 00:15:27.790 --> 00:15:27.800 align:start position:0% passing to your contract when they're 00:15:27.800 --> 00:15:30.389 align:start position:0% passing to your contract when they're calling<00:15:28.199> them<00:15:28.639> so<00:15:29.000> this<00:15:29.120> is<00:15:29.199> a<00:15:29.360> swap<00:15:29.800> on<00:15:30.000> Unis 00:15:30.389 --> 00:15:30.399 align:start position:0% calling them so this is a swap on Unis 00:15:30.399 --> 00:15:33.470 align:start position:0% calling them so this is a swap on Unis swap<00:15:30.639> V2<00:15:31.639> uh<00:15:31.800> obviously<00:15:32.160> if<00:15:32.279> you<00:15:32.399> don't<00:15:32.639> know 00:15:33.470 --> 00:15:33.480 align:start position:0% swap V2 uh obviously if you don't know 00:15:33.480 --> 00:15:35.069 align:start position:0% swap V2 uh obviously if you don't know like 00:15:35.069 --> 00:15:35.079 align:start position:0% like 00:15:35.079 --> 00:15:38.389 align:start position:0% like um<00:15:36.079> you<00:15:36.199> might<00:15:36.519> not<00:15:36.720> know<00:15:37.199> what<00:15:37.360> are<00:15:37.839> these 00:15:38.389 --> 00:15:38.399 align:start position:0% um you might not know what are these 00:15:38.399 --> 00:15:40.749 align:start position:0% um you might not know what are these numbers<00:15:38.920> but<00:15:39.120> basically<00:15:39.839> in<00:15:39.959> your<00:15:40.199> contract 00:15:40.749 --> 00:15:40.759 align:start position:0% numbers but basically in your contract 00:15:40.759 --> 00:15:43.629 align:start position:0% numbers but basically in your contract you're<00:15:41.000> supposed<00:15:41.680> to<00:15:42.680> so<00:15:43.000> don't<00:15:43.120> don't<00:15:43.319> worry 00:15:43.629 --> 00:15:43.639 align:start position:0% you're supposed to so don't don't worry 00:15:43.639 --> 00:15:45.389 align:start position:0% you're supposed to so don't don't worry too<00:15:43.800> much<00:15:44.000> about<00:15:44.279> that<00:15:44.639> but<00:15:44.800> yeah<00:15:45.040> basically 00:15:45.389 --> 00:15:45.399 align:start position:0% too much about that but yeah basically 00:15:45.399 --> 00:15:47.350 align:start position:0% too much about that but yeah basically we<00:15:45.519> can<00:15:45.639> see<00:15:45.839> like<00:15:46.000> the<00:15:46.120> the<00:15:46.240> first<00:15:46.480> bites<00:15:47.160> just 00:15:47.350 --> 00:15:47.360 align:start position:0% we can see like the the first bites just 00:15:47.360 --> 00:15:49.829 align:start position:0% we can see like the the first bites just the<00:15:47.560> signature<00:15:48.120> of<00:15:48.399> the<00:15:48.680> the<00:15:48.839> function<00:15:49.639> and 00:15:49.829 --> 00:15:49.839 align:start position:0% the signature of the the function and 00:15:49.839 --> 00:15:52.389 align:start position:0% the signature of the the function and then<00:15:50.319> all<00:15:50.480> the<00:15:50.680> other<00:15:51.279> values<00:15:51.720> like<00:15:51.920> after<00:15:52.199> all 00:15:52.389 --> 00:15:52.399 align:start position:0% then all the other values like after all 00:15:52.399 --> 00:15:55.629 align:start position:0% then all the other values like after all the<00:15:52.600> zeros<00:15:53.360> these<00:15:53.519> are<00:15:53.800> just<00:15:54.040> like<00:15:54.399> um<00:15:55.199> values 00:15:55.629 --> 00:15:55.639 align:start position:0% the zeros these are just like um values 00:15:55.639 --> 00:15:57.590 align:start position:0% the zeros these are just like um values like<00:15:55.880> amounts<00:15:56.279> for<00:15:56.480> example<00:15:56.920> that<00:15:57.040> are<00:15:57.279> passed 00:15:57.590 --> 00:15:57.600 align:start position:0% like amounts for example that are passed 00:15:57.600 --> 00:16:02.030 align:start position:0% like amounts for example that are passed around<00:15:58.079> or<00:15:58.240> maybe<00:15:58.519> addresses 00:16:02.030 --> 00:16:02.040 align:start position:0% 00:16:02.040 --> 00:16:04.509 align:start position:0% uh<00:16:02.360> yeah<00:16:02.600> just<00:16:03.000> like<00:16:03.160> a<00:16:03.360> very<00:16:03.600> cool<00:16:03.920> website<00:16:04.399> if 00:16:04.509 --> 00:16:04.519 align:start position:0% uh yeah just like a very cool website if 00:16:04.519 --> 00:16:07.269 align:start position:0% uh yeah just like a very cool website if you<00:16:04.639> want<00:16:04.839> to<00:16:05.079> be<00:16:05.560> or<00:16:05.880> get<00:16:06.160> more<00:16:06.480> familiar<00:16:07.079> with 00:16:07.269 --> 00:16:07.279 align:start position:0% you want to be or get more familiar with 00:16:07.279 --> 00:16:10.189 align:start position:0% you want to be or get more familiar with like<00:16:07.600> the<00:16:08.040> how<00:16:08.199> The<00:16:08.319> evm<00:16:08.839> Works<00:16:09.639> uh<00:16:09.720> you<00:16:09.839> can<00:16:10.040> go 00:16:10.189 --> 00:16:10.199 align:start position:0% like the how The evm Works uh you can go 00:16:10.199 --> 00:16:13.350 align:start position:0% like the how The evm Works uh you can go on<00:16:10.480> evm<00:16:11.000> do<00:16:11.319> codes<00:16:12.319> uh<00:16:12.639> there<00:16:12.800> are<00:16:13.040> many 00:16:13.350 --> 00:16:13.360 align:start position:0% on evm do codes uh there are many 00:16:13.360 --> 00:16:15.470 align:start position:0% on evm do codes uh there are many different<00:16:13.720> sections<00:16:14.519> the<00:16:14.639> first<00:16:14.880> one<00:16:15.120> is<00:16:15.279> like 00:16:15.470 --> 00:16:15.480 align:start position:0% different sections the first one is like 00:16:15.480 --> 00:16:17.590 align:start position:0% different sections the first one is like up<00:16:15.800> codes<00:16:16.199> which<00:16:16.319> is<00:16:16.800> this<00:16:16.920> is<00:16:17.079> what<00:16:17.199> I<00:16:17.319> showed 00:16:17.590 --> 00:16:17.600 align:start position:0% up codes which is this is what I showed 00:16:17.600 --> 00:16:19.749 align:start position:0% up codes which is this is what I showed you<00:16:17.800> earlier<00:16:18.480> just<00:16:18.680> like<00:16:18.839> a<00:16:19.000> list<00:16:19.279> of<00:16:19.480> all<00:16:19.600> the 00:16:19.749 --> 00:16:19.759 align:start position:0% you earlier just like a list of all the 00:16:19.759 --> 00:16:22.150 align:start position:0% you earlier just like a list of all the up<00:16:20.000> codes<00:16:20.639> just<00:16:20.880> explaining<00:16:21.519> exactly<00:16:21.959> how 00:16:22.150 --> 00:16:22.160 align:start position:0% up codes just explaining exactly how 00:16:22.160 --> 00:16:25.430 align:start position:0% up codes just explaining exactly how they<00:16:22.440> work<00:16:22.800> how<00:16:23.079> they<00:16:23.399> work<00:16:24.399> it's<00:16:24.600> like<00:16:24.759> a<00:16:25.040> very 00:16:25.430 --> 00:16:25.440 align:start position:0% they work how they work it's like a very 00:16:25.440 --> 00:16:28.629 align:start position:0% they work how they work it's like a very very<00:16:25.920> uh<00:16:26.800> convenient<00:16:27.800> uh<00:16:28.079> and<00:16:28.279> then<00:16:28.399> you<00:16:28.519> have 00:16:28.629 --> 00:16:28.639 align:start position:0% very uh convenient uh and then you have 00:16:28.639 --> 00:16:30.910 align:start position:0% very uh convenient uh and then you have the<00:16:28.959> playground<00:16:29.720> so<00:16:29.920> you<00:16:30.040> can<00:16:30.240> write<00:16:30.519> some 00:16:30.910 --> 00:16:30.920 align:start position:0% the playground so you can write some 00:16:30.920 --> 00:16:34.990 align:start position:0% the playground so you can write some solidity<00:16:31.920> code<00:16:32.920> uh<00:16:33.120> U<00:16:33.560> code<00:16:34.279> I<00:16:34.399> think<00:16:34.600> also 00:16:34.990 --> 00:16:35.000 align:start position:0% solidity code uh U code I think also 00:16:35.000 --> 00:16:37.790 align:start position:0% solidity code uh U code I think also like<00:16:35.360> uh<00:16:35.800> memonic<00:16:36.319> by<00:16:36.600> code<00:16:37.199> and<00:16:37.360> then<00:16:37.519> you<00:16:37.600> can 00:16:37.790 --> 00:16:37.800 align:start position:0% like uh memonic by code and then you can 00:16:37.800 --> 00:16:40.110 align:start position:0% like uh memonic by code and then you can just<00:16:38.040> hit<00:16:38.360> the<00:16:38.560> the<00:16:38.680> Run<00:16:39.000> button<00:16:39.720> and<00:16:39.839> you<00:16:39.959> can 00:16:40.110 --> 00:16:40.120 align:start position:0% just hit the the Run button and you can 00:16:40.120 --> 00:16:41.790 align:start position:0% just hit the the Run button and you can see<00:16:40.360> like<00:16:40.519> what's<00:16:40.720> happening<00:16:41.120> step<00:16:41.360> by<00:16:41.560> step 00:16:41.790 --> 00:16:41.800 align:start position:0% see like what's happening step by step 00:16:41.800 --> 00:16:43.829 align:start position:0% see like what's happening step by step into<00:16:42.079> the<00:16:42.199> memory<00:16:42.680> the<00:16:42.839> stack<00:16:43.199> the<00:16:43.279> storage 00:16:43.829 --> 00:16:43.839 align:start position:0% into the memory the stack the storage 00:16:43.839 --> 00:16:45.670 align:start position:0% into the memory the stack the storage transend<00:16:44.120> and<00:16:44.319> storage<00:16:45.079> the<00:16:45.240> return<00:16:45.440> return 00:16:45.670 --> 00:16:45.680 align:start position:0% transend and storage the return return 00:16:45.680 --> 00:16:49.230 align:start position:0% transend and storage the return return values<00:16:46.440> so<00:16:46.680> it's<00:16:46.880> it's<00:16:47.680> extremely<00:16:48.680> convenient 00:16:49.230 --> 00:16:49.240 align:start position:0% values so it's it's extremely convenient 00:16:49.240 --> 00:16:52.590 align:start position:0% values so it's it's extremely convenient and<00:16:49.399> it's<00:16:49.639> a<00:16:49.920> great<00:16:50.240> resource<00:16:50.800> just<00:16:51.079> to<00:16:52.079> to<00:16:52.279> use 00:16:52.590 --> 00:16:52.600 align:start position:0% and it's a great resource just to to use 00:16:52.600 --> 00:16:55.509 align:start position:0% and it's a great resource just to to use like<00:16:52.800> to<00:16:53.040> to<00:16:53.240> learn<00:16:54.079> how<00:16:54.360> the<00:16:54.519> evm<00:16:54.959> works 00:16:55.509 --> 00:16:55.519 align:start position:0% like to to learn how the evm works 00:16:55.519 --> 00:17:00.430 align:start position:0% like to to learn how the evm works there's<00:16:55.839> like<00:16:55.959> a<00:16:56.360> half<00:16:57.360> uh<00:16:58.279> Fork<00:16:59.199> for<00:16:59.680> this<00:17:00.040> but 00:17:00.430 --> 00:17:00.440 align:start position:0% there's like a half uh Fork for this but 00:17:00.440 --> 00:17:03.230 align:start position:0% there's like a half uh Fork for this but might<00:17:00.639> not<00:17:00.800> be<00:17:00.959> updated<00:17:01.920> so<00:17:02.160> I'm<00:17:02.480> not<00:17:02.720> going<00:17:02.920> to 00:17:03.230 --> 00:17:03.240 align:start position:0% might not be updated so I'm not going to 00:17:03.240 --> 00:17:06.429 align:start position:0% might not be updated so I'm not going to to<00:17:03.360> show<00:17:03.600> it<00:17:04.280> here<00:17:05.280> and<00:17:05.799> yeah<00:17:05.919> I<00:17:06.039> guess<00:17:06.240> it's 00:17:06.429 --> 00:17:06.439 align:start position:0% to show it here and yeah I guess it's 00:17:06.439 --> 00:17:09.189 align:start position:0% to show it here and yeah I guess it's time<00:17:06.640> to<00:17:07.120> just<00:17:07.360> go<00:17:07.559> through<00:17:07.839> like<00:17:08.000> all<00:17:08.240> the<00:17:09.039> the 00:17:09.189 --> 00:17:09.199 align:start position:0% time to just go through like all the the 00:17:09.199 --> 00:17:13.270 align:start position:0% time to just go through like all the the things<00:17:09.480> we<00:17:09.679> have<00:17:09.959> in<00:17:10.679> half<00:17:11.679> so<00:17:12.039> first<00:17:12.400> like<00:17:13.079> in 00:17:13.270 --> 00:17:13.280 align:start position:0% things we have in half so first like in 00:17:13.280 --> 00:17:16.150 align:start position:0% things we have in half so first like in half<00:17:13.520> you<00:17:13.640> can<00:17:14.039> like<00:17:14.319> have<00:17:15.079> um<00:17:15.679> you<00:17:15.880> we<00:17:16.000> have 00:17:16.150 --> 00:17:16.160 align:start position:0% half you can like have um you we have 00:17:16.160 --> 00:17:18.230 align:start position:0% half you can like have um you we have the<00:17:16.319> interface<00:17:16.919> definition<00:17:17.880> which<00:17:18.039> is 00:17:18.230 --> 00:17:18.240 align:start position:0% the interface definition which is 00:17:18.240 --> 00:17:20.750 align:start position:0% the interface definition which is something<00:17:18.959> very<00:17:19.319> similar<00:17:19.760> to<00:17:20.000> what<00:17:20.160> we<00:17:20.360> have 00:17:20.750 --> 00:17:20.760 align:start position:0% something very similar to what we have 00:17:20.760 --> 00:17:23.510 align:start position:0% something very similar to what we have in<00:17:21.039> solidity<00:17:21.720> or<00:17:21.959> Viper<00:17:22.319> or<00:17:22.480> whatever<00:17:23.160> you<00:17:23.280> can 00:17:23.510 --> 00:17:23.520 align:start position:0% in solidity or Viper or whatever you can 00:17:23.520 --> 00:17:26.029 align:start position:0% in solidity or Viper or whatever you can just<00:17:23.760> like<00:17:24.160> Define<00:17:24.799> functions<00:17:25.679> you<00:17:25.799> can 00:17:26.029 --> 00:17:26.039 align:start position:0% just like Define functions you can 00:17:26.039 --> 00:17:29.029 align:start position:0% just like Define functions you can Define<00:17:26.600> events<00:17:27.079> you<00:17:27.199> can<00:17:27.439> Define<00:17:28.280> uh<00:17:28.400> errors 00:17:29.029 --> 00:17:29.039 align:start position:0% Define events you can Define uh errors 00:17:29.039 --> 00:17:30.950 align:start position:0% Define events you can Define uh errors also<00:17:29.360> it's<00:17:29.520> not<00:17:29.760> there<00:17:29.960> but<00:17:30.080> you<00:17:30.160> can<00:17:30.400> also<00:17:30.720> do 00:17:30.950 --> 00:17:30.960 align:start position:0% also it's not there but you can also do 00:17:30.960 --> 00:17:33.390 align:start position:0% also it's not there but you can also do it<00:17:31.840> um<00:17:32.120> and<00:17:32.280> then<00:17:32.400> you<00:17:32.559> just<00:17:32.760> have<00:17:32.919> to<00:17:33.120> pass 00:17:33.390 --> 00:17:33.400 align:start position:0% it um and then you just have to pass 00:17:33.400 --> 00:17:36.430 align:start position:0% it um and then you just have to pass like<00:17:33.559> some<00:17:34.440> parameters<00:17:35.360> so<00:17:35.640> this<00:17:35.760> will<00:17:36.000> be 00:17:36.430 --> 00:17:36.440 align:start position:0% like some parameters so this will be 00:17:36.440 --> 00:17:39.430 align:start position:0% like some parameters so this will be useful<00:17:37.000> in<00:17:37.120> two<00:17:37.400> cases<00:17:38.280> either<00:17:38.600> to<00:17:38.960> Define 00:17:39.430 --> 00:17:39.440 align:start position:0% useful in two cases either to Define 00:17:39.440 --> 00:17:42.029 align:start position:0% useful in two cases either to Define like<00:17:39.600> a<00:17:39.799> function<00:17:40.520> so<00:17:40.919> people<00:17:41.320> can<00:17:41.559> call<00:17:41.840> your 00:17:42.029 --> 00:17:42.039 align:start position:0% like a function so people can call your 00:17:42.039 --> 00:17:44.230 align:start position:0% like a function so people can call your smart<00:17:42.440> contract<00:17:43.160> or<00:17:43.360> if<00:17:43.440> you<00:17:43.559> want<00:17:43.760> to<00:17:43.919> call 00:17:44.230 --> 00:17:44.240 align:start position:0% smart contract or if you want to call 00:17:44.240 --> 00:17:45.990 align:start position:0% smart contract or if you want to call like<00:17:44.440> another<00:17:44.880> contract<00:17:45.280> let's<00:17:45.440> say<00:17:45.640> like<00:17:45.840> an 00:17:45.990 --> 00:17:46.000 align:start position:0% like another contract let's say like an 00:17:46.000 --> 00:17:48.870 align:start position:0% like another contract let's say like an year<00:17:46.280> C20<00:17:47.039> then<00:17:47.200> you<00:17:47.320> can<00:17:48.080> Define<00:17:48.640> the 00:17:48.870 --> 00:17:48.880 align:start position:0% year C20 then you can Define the 00:17:48.880 --> 00:17:51.510 align:start position:0% year C20 then you can Define the transfer<00:17:49.440> function<00:17:49.919> and<00:17:50.039> then<00:17:50.320> you<00:17:50.440> will<00:17:50.799> use 00:17:51.510 --> 00:17:51.520 align:start position:0% transfer function and then you will use 00:17:51.520 --> 00:17:56.270 align:start position:0% transfer function and then you will use this<00:17:51.960> definition<00:17:52.520> later<00:17:52.919> on<00:17:53.480> to<00:17:53.720> call<00:17:53.960> the 00:17:56.270 --> 00:17:56.280 align:start position:0% 00:17:56.280 --> 00:17:59.149 align:start position:0% contract<00:17:57.280> uh<00:17:57.400> we<00:17:57.520> do<00:17:57.760> have<00:17:57.960> some<00:17:58.440> build 00:17:59.149 --> 00:17:59.159 align:start position:0% contract uh we do have some build 00:17:59.159 --> 00:18:01.789 align:start position:0% contract uh we do have some build functions<00:17:59.919> in<00:18:00.280> half<00:18:01.000> so<00:18:01.240> we<00:18:01.400> have<00:18:01.600> the 00:18:01.789 --> 00:18:01.799 align:start position:0% functions in half so we have the 00:18:01.799 --> 00:18:04.590 align:start position:0% functions in half so we have the function<00:18:02.280> signature<00:18:03.039> the<00:18:03.240> even<00:18:03.640> hash<00:18:04.120> and<00:18:04.320> the 00:18:04.590 --> 00:18:04.600 align:start position:0% function signature the even hash and the 00:18:04.600 --> 00:18:07.310 align:start position:0% function signature the even hash and the ear<00:18:05.120> function<00:18:06.039> uh<00:18:06.159> these<00:18:06.360> three<00:18:06.600> functions 00:18:07.310 --> 00:18:07.320 align:start position:0% ear function uh these three functions 00:18:07.320 --> 00:18:09.750 align:start position:0% ear function uh these three functions Works<00:18:08.080> more<00:18:08.240> or<00:18:08.360> less<00:18:08.559> the<00:18:08.679> same<00:18:08.960> way<00:18:09.400> and<00:18:09.559> it's 00:18:09.750 --> 00:18:09.760 align:start position:0% Works more or less the same way and it's 00:18:09.760 --> 00:18:13.470 align:start position:0% Works more or less the same way and it's related<00:18:10.240> to<00:18:11.159> the<00:18:11.799> interface<00:18:12.400> definition<00:18:13.280> once 00:18:13.470 --> 00:18:13.480 align:start position:0% related to the interface definition once 00:18:13.480 --> 00:18:15.909 align:start position:0% related to the interface definition once you<00:18:13.679> define<00:18:14.120> let's<00:18:14.280> say<00:18:14.440> for<00:18:14.600> example<00:18:15.159> approve 00:18:15.909 --> 00:18:15.919 align:start position:0% you define let's say for example approve 00:18:15.919 --> 00:18:17.750 align:start position:0% you define let's say for example approve and<00:18:16.039> you<00:18:16.159> want<00:18:16.320> to<00:18:16.520> call<00:18:16.880> approve<00:18:17.559> then<00:18:17.679> you 00:18:17.750 --> 00:18:17.760 align:start position:0% and you want to call approve then you 00:18:17.760 --> 00:18:20.830 align:start position:0% and you want to call approve then you will<00:18:17.960> be<00:18:18.080> able<00:18:18.280> to<00:18:18.400> use<00:18:18.640> like<00:18:18.880> function<00:18:19.840> Sig 00:18:20.830 --> 00:18:20.840 align:start position:0% will be able to use like function Sig 00:18:20.840 --> 00:18:23.470 align:start position:0% will be able to use like function Sig and<00:18:20.960> you<00:18:21.120> put<00:18:21.400> just<00:18:21.760> approve<00:18:22.600> um<00:18:23.080> inside<00:18:23.360> of 00:18:23.470 --> 00:18:23.480 align:start position:0% and you put just approve um inside of 00:18:23.480 --> 00:18:25.630 align:start position:0% and you put just approve um inside of the<00:18:23.640> parentheses<00:18:24.520> and<00:18:24.640> it<00:18:24.760> will<00:18:25.039> give<00:18:25.159> you<00:18:25.440> the 00:18:25.630 --> 00:18:25.640 align:start position:0% the parentheses and it will give you the 00:18:25.640 --> 00:18:27.590 align:start position:0% the parentheses and it will give you the signature<00:18:26.120> of<00:18:26.280> the<00:18:26.440> function<00:18:27.080> so<00:18:27.240> you<00:18:27.400> can 00:18:27.590 --> 00:18:27.600 align:start position:0% signature of the function so you can 00:18:27.600 --> 00:18:29.909 align:start position:0% signature of the function so you can call<00:18:27.840> it<00:18:28.440> the<00:18:28.559> same<00:18:28.919> thing<00:18:29.080> for<00:18:29.280> the<00:18:29.440> event<00:18:29.840> if 00:18:29.909 --> 00:18:29.919 align:start position:0% call it the same thing for the event if 00:18:29.919 --> 00:18:32.190 align:start position:0% call it the same thing for the event if you<00:18:30.039> want<00:18:30.200> to<00:18:30.559> emit<00:18:30.840> an<00:18:31.039> event<00:18:31.640> or<00:18:31.799> if<00:18:31.880> you<00:18:32.000> want 00:18:32.190 --> 00:18:32.200 align:start position:0% you want to emit an event or if you want 00:18:32.200 --> 00:18:35.029 align:start position:0% you want to emit an event or if you want to<00:18:32.679> revert<00:18:33.159> then<00:18:33.280> you<00:18:33.400> can<00:18:33.559> use<00:18:33.840> that<00:18:34.000> for<00:18:34.880> the 00:18:35.029 --> 00:18:35.039 align:start position:0% to revert then you can use that for the 00:18:35.039 --> 00:18:36.990 align:start position:0% to revert then you can use that for the error<00:18:35.360> and<00:18:35.559> get<00:18:35.799> the<00:18:36.000> the 00:18:36.990 --> 00:18:37.000 align:start position:0% error and get the the 00:18:37.000 --> 00:18:40.149 align:start position:0% error and get the the selector<00:18:38.000> we<00:18:38.200> have<00:18:38.440> also<00:18:39.000> a<00:18:39.159> right<00:18:39.520> pad<00:18:40.039> which 00:18:40.149 --> 00:18:40.159 align:start position:0% selector we have also a right pad which 00:18:40.159 --> 00:18:43.190 align:start position:0% selector we have also a right pad which is<00:18:40.360> just<00:18:40.640> like<00:18:41.120> shifting<00:18:41.840> a<00:18:42.039> value<00:18:42.760> from<00:18:43.000> the 00:18:43.190 --> 00:18:43.200 align:start position:0% is just like shifting a value from the 00:18:43.200 --> 00:18:45.710 align:start position:0% is just like shifting a value from the left<00:18:43.440> to<00:18:43.679> to<00:18:43.880> the<00:18:44.080> right<00:18:45.000> and<00:18:45.240> then<00:18:45.400> we<00:18:45.520> have 00:18:45.710 --> 00:18:45.720 align:start position:0% left to to the right and then we have 00:18:45.720 --> 00:18:48.350 align:start position:0% left to to the right and then we have like<00:18:45.880> table<00:18:46.240> start<00:18:46.720> and<00:18:46.960> table<00:18:47.400> size 00:18:48.350 --> 00:18:48.360 align:start position:0% like table start and table size 00:18:48.360 --> 00:18:50.630 align:start position:0% like table start and table size basically<00:18:48.720> it's<00:18:48.919> like<00:18:49.120> a<00:18:49.320> way<00:18:49.520> to<00:18:50.039> write 00:18:50.630 --> 00:18:50.640 align:start position:0% basically it's like a way to write 00:18:50.640 --> 00:18:54.430 align:start position:0% basically it's like a way to write switch<00:18:51.360> statements<00:18:52.360> uh<00:18:52.480> in<00:18:53.080> half<00:18:54.080> we'll<00:18:54.320> get 00:18:54.430 --> 00:18:54.440 align:start position:0% switch statements uh in half we'll get 00:18:54.440 --> 00:18:57.470 align:start position:0% switch statements uh in half we'll get to<00:18:54.679> that<00:18:55.320> uh<00:18:55.559> in<00:18:55.720> a<00:18:55.919> bit 00:18:57.470 --> 00:18:57.480 align:start position:0% to that uh in a bit 00:18:57.480 --> 00:18:59.750 align:start position:0% to that uh in a bit though<00:18:58.480> and<00:18:58.880> yeah<00:18:59.039> this<00:18:59.120> is<00:18:59.280> what<00:18:59.400> I<00:18:59.480> showed 00:18:59.750 --> 00:18:59.760 align:start position:0% though and yeah this is what I showed 00:18:59.760 --> 00:19:01.750 align:start position:0% though and yeah this is what I showed you<00:19:00.039> like<00:19:00.520> uh<00:19:00.760> at<00:19:00.880> the<00:19:01.080> top<00:19:01.280> we're<00:19:01.559> just 00:19:01.750 --> 00:19:01.760 align:start position:0% you like uh at the top we're just 00:19:01.760 --> 00:19:05.070 align:start position:0% you like uh at the top we're just defining<00:19:02.440> like<00:19:02.600> two<00:19:03.080> errors<00:19:04.080> Panic<00:19:04.440> error<00:19:04.840> and 00:19:05.070 --> 00:19:05.080 align:start position:0% defining like two errors Panic error and 00:19:05.080 --> 00:19:08.230 align:start position:0% defining like two errors Panic error and error<00:19:05.679> like<00:19:06.240> that's<00:19:06.440> very<00:19:06.880> original<00:19:07.880> uh<00:19:08.039> but 00:19:08.230 --> 00:19:08.240 align:start position:0% error like that's very original uh but 00:19:08.240 --> 00:19:11.510 align:start position:0% error like that's very original uh but yeah<00:19:08.480> then<00:19:08.840> later<00:19:09.159> on<00:19:09.440> we<00:19:09.559> want<00:19:09.799> to<00:19:10.520> revert<00:19:11.360> and 00:19:11.510 --> 00:19:11.520 align:start position:0% yeah then later on we want to revert and 00:19:11.520 --> 00:19:13.350 align:start position:0% yeah then later on we want to revert and then<00:19:11.840> what<00:19:12.000> we<00:19:12.120> are<00:19:12.280> going<00:19:12.520> to<00:19:12.679> do<00:19:12.880> we<00:19:13.000> can<00:19:13.200> just 00:19:13.350 --> 00:19:13.360 align:start position:0% then what we are going to do we can just 00:19:13.360 --> 00:19:16.390 align:start position:0% then what we are going to do we can just do<00:19:13.600> like<00:19:13.919> a<00:19:14.400> uncore<00:19:15.039> underscore<00:19:15.679> a<00:19:16.120> and<00:19:16.280> then 00:19:16.390 --> 00:19:16.400 align:start position:0% do like a uncore underscore a and then 00:19:16.400 --> 00:19:20.149 align:start position:0% do like a uncore underscore a and then we<00:19:16.559> just<00:19:16.760> put<00:19:17.080> the<00:19:18.039> um<00:19:19.039> name<00:19:19.360> of<00:19:19.520> the<00:19:19.679> ER<00:19:20.039> you 00:19:20.149 --> 00:19:20.159 align:start position:0% we just put the um name of the ER you 00:19:20.159 --> 00:19:22.750 align:start position:0% we just put the um name of the ER you want<00:19:20.320> to<00:19:20.480> use<00:19:21.080> and<00:19:21.240> then<00:19:21.600> this<00:19:21.799> will<00:19:22.120> add<00:19:22.480> the 00:19:22.750 --> 00:19:22.760 align:start position:0% want to use and then this will add the 00:19:22.760 --> 00:19:26.149 align:start position:0% want to use and then this will add the selector<00:19:23.720> inside<00:19:24.240> of<00:19:24.559> our<00:19:24.960> code<00:19:25.640> and<00:19:25.840> then<00:19:26.039> we 00:19:26.149 --> 00:19:26.159 align:start position:0% selector inside of our code and then we 00:19:26.159 --> 00:19:28.190 align:start position:0% selector inside of our code and then we can<00:19:26.400> just<00:19:26.679> like<00:19:27.080> uh<00:19:27.440> in<00:19:27.600> this<00:19:27.760> case<00:19:27.960> we<00:19:28.039> are 00:19:28.190 --> 00:19:28.200 align:start position:0% can just like uh in this case we are 00:19:28.200 --> 00:19:30.669 align:start position:0% can just like uh in this case we are reverting<00:19:28.840> with<00:19:29.039> some<00:19:29.320> parameters<00:19:30.159> so<00:19:30.360> we<00:19:30.480> can 00:19:30.669 --> 00:19:30.679 align:start position:0% reverting with some parameters so we can 00:19:30.679 --> 00:19:32.470 align:start position:0% reverting with some parameters so we can just<00:19:30.840> like<00:19:31.000> sore<00:19:31.400> these<00:19:31.600> parameters<00:19:32.200> inside 00:19:32.470 --> 00:19:32.480 align:start position:0% just like sore these parameters inside 00:19:32.480 --> 00:19:33.470 align:start position:0% just like sore these parameters inside of<00:19:32.679> the 00:19:33.470 --> 00:19:33.480 align:start position:0% of the 00:19:33.480 --> 00:19:35.549 align:start position:0% of the memory<00:19:34.480> then<00:19:34.640> we<00:19:34.840> just<00:19:35.000> have<00:19:35.120> to<00:19:35.280> call<00:19:35.440> the 00:19:35.549 --> 00:19:35.559 align:start position:0% memory then we just have to call the 00:19:35.559 --> 00:19:39.029 align:start position:0% memory then we just have to call the revert 00:19:39.029 --> 00:19:39.039 align:start position:0% 00:19:39.039 --> 00:19:41.830 align:start position:0% function<00:19:40.039> so<00:19:40.520> another<00:19:40.919> thing<00:19:41.240> that<00:19:41.440> we<00:19:41.559> can 00:19:41.830 --> 00:19:41.840 align:start position:0% function so another thing that we can 00:19:41.840 --> 00:19:45.430 align:start position:0% function so another thing that we can Define<00:19:42.480> actually<00:19:43.400> um<00:19:44.080> constants<00:19:44.840> so<00:19:45.200> I<00:19:45.280> think 00:19:45.430 --> 00:19:45.440 align:start position:0% Define actually um constants so I think 00:19:45.440 --> 00:19:46.990 align:start position:0% Define actually um constants so I think it's<00:19:45.679> pretty<00:19:45.960> straightforward<00:19:46.600> you<00:19:46.720> have<00:19:46.840> a 00:19:46.990 --> 00:19:47.000 align:start position:0% it's pretty straightforward you have a 00:19:47.000 --> 00:19:49.950 align:start position:0% it's pretty straightforward you have a number<00:19:47.640> you<00:19:47.799> can<00:19:48.000> just<00:19:48.200> Define<00:19:48.640> like<00:19:48.960> a<00:19:49.520> number 00:19:49.950 --> 00:19:49.960 align:start position:0% number you can just Define like a number 00:19:49.960 --> 00:19:53.990 align:start position:0% number you can just Define like a number so<00:19:50.080> it's<00:19:50.280> like<00:19:50.480> o<00:19:50.880> x<00:19:51.840> 420<00:19:52.840> this<00:19:52.960> is<00:19:53.200> an<00:19:53.600> EXA 00:19:53.990 --> 00:19:54.000 align:start position:0% so it's like o x 420 this is an EXA 00:19:54.000 --> 00:19:56.870 align:start position:0% so it's like o x 420 this is an EXA decimal<00:19:54.480> value<00:19:55.039> but<00:19:55.159> you<00:19:55.280> can<00:19:55.520> also<00:19:55.880> Define<00:19:56.679> um 00:19:56.870 --> 00:19:56.880 align:start position:0% decimal value but you can also Define um 00:19:56.880 --> 00:19:59.950 align:start position:0% decimal value but you can also Define um numbers<00:19:57.880> uh<00:19:58.000> using<00:19:58.360> like<00:19:58.720> decimal<00:19:59.200> values 00:19:59.950 --> 00:19:59.960 align:start position:0% numbers uh using like decimal values 00:19:59.960 --> 00:20:02.990 align:start position:0% numbers uh using like decimal values most<00:20:00.159> of<00:20:00.280> the<00:20:00.440> people<00:20:01.200> do<00:20:01.360> it<00:20:01.559> this<00:20:01.880> way<00:20:02.880> and 00:20:02.990 --> 00:20:03.000 align:start position:0% most of the people do it this way and 00:20:03.000 --> 00:20:05.190 align:start position:0% most of the people do it this way and then<00:20:03.159> whenever<00:20:03.520> you<00:20:03.600> want<00:20:03.760> to<00:20:03.919> use<00:20:04.280> the<00:20:04.880> your 00:20:05.190 --> 00:20:05.200 align:start position:0% then whenever you want to use the your 00:20:05.200 --> 00:20:07.110 align:start position:0% then whenever you want to use the your constant<00:20:05.679> then<00:20:05.799> you<00:20:05.960> just<00:20:06.159> have<00:20:06.280> to<00:20:06.480> put<00:20:06.960> the 00:20:07.110 --> 00:20:07.120 align:start position:0% constant then you just have to put the 00:20:07.120 --> 00:20:09.750 align:start position:0% constant then you just have to put the name<00:20:07.880> inside<00:20:08.240> of<00:20:08.360> some<00:20:08.559> brackets<00:20:09.240> and<00:20:09.400> then<00:20:09.520> we 00:20:09.750 --> 00:20:09.760 align:start position:0% name inside of some brackets and then we 00:20:09.760 --> 00:20:14.470 align:start position:0% name inside of some brackets and then we just<00:20:10.000> like<00:20:10.440> uh<00:20:10.600> input<00:20:11.080> the<00:20:11.280> the<00:20:11.400> right 00:20:14.470 --> 00:20:14.480 align:start position:0% 00:20:14.480 --> 00:20:17.669 align:start position:0% value<00:20:15.480> uh<00:20:15.640> then<00:20:15.799> we<00:20:15.960> have<00:20:16.240> jump<00:20:16.640> labels<00:20:17.400> so 00:20:17.669 --> 00:20:17.679 align:start position:0% value uh then we have jump labels so 00:20:17.679 --> 00:20:20.870 align:start position:0% value uh then we have jump labels so jump<00:20:18.000> labels<00:20:18.480> are<00:20:18.840> defined<00:20:19.360> within<00:20:19.799> a<00:20:20.000> macro 00:20:20.870 --> 00:20:20.880 align:start position:0% jump labels are defined within a macro 00:20:20.880 --> 00:20:23.470 align:start position:0% jump labels are defined within a macro or<00:20:21.120> a<00:20:21.320> function<00:20:22.080> we'll<00:20:22.240> see<00:20:22.400> what<00:20:22.559> they<00:20:23.080> a<00:20:23.240> bit 00:20:23.470 --> 00:20:23.480 align:start position:0% or a function we'll see what they a bit 00:20:23.480 --> 00:20:26.029 align:start position:0% or a function we'll see what they a bit later<00:20:24.159> but<00:20:24.360> basically<00:20:25.240> like<00:20:25.520> it's<00:20:25.760> very 00:20:26.029 --> 00:20:26.039 align:start position:0% later but basically like it's very 00:20:26.039 --> 00:20:27.669 align:start position:0% later but basically like it's very simple<00:20:26.400> you<00:20:26.559> have<00:20:26.840> just<00:20:27.039> like<00:20:27.159> a<00:20:27.320> piece<00:20:27.480> of 00:20:27.669 --> 00:20:27.679 align:start position:0% simple you have just like a piece of 00:20:27.679 --> 00:20:30.789 align:start position:0% simple you have just like a piece of code<00:20:28.000> like<00:20:28.280> for<00:20:28.440> examp<00:20:28.679> example<00:20:29.320> success<00:20:29.919> here 00:20:30.789 --> 00:20:30.799 align:start position:0% code like for examp example success here 00:20:30.799 --> 00:20:33.549 align:start position:0% code like for examp example success here success<00:20:31.240> is<00:20:31.480> just<00:20:31.679> defined<00:20:32.080> by<00:20:32.320> this<00:20:33.200> um 00:20:33.549 --> 00:20:33.559 align:start position:0% success is just defined by this um 00:20:33.559 --> 00:20:35.510 align:start position:0% success is just defined by this um instruction<00:20:34.159> so<00:20:34.400> like<00:20:34.799> we<00:20:34.960> we<00:20:35.120> store 00:20:35.510 --> 00:20:35.520 align:start position:0% instruction so like we we store 00:20:35.520 --> 00:20:38.909 align:start position:0% instruction so like we we store something<00:20:35.960> and<00:20:36.120> then<00:20:36.640> we<00:20:36.760> just<00:20:37.480> return<00:20:38.480> and<00:20:38.640> so 00:20:38.909 --> 00:20:38.919 align:start position:0% something and then we just return and so 00:20:38.919 --> 00:20:40.510 align:start position:0% something and then we just return and so what<00:20:39.000> is<00:20:39.159> going<00:20:39.320> to<00:20:39.520> happen<00:20:40.000> if<00:20:40.120> you<00:20:40.240> look<00:20:40.400> at 00:20:40.510 --> 00:20:40.520 align:start position:0% what is going to happen if you look at 00:20:40.520 --> 00:20:42.789 align:start position:0% what is going to happen if you look at the<00:20:40.679> top<00:20:40.960> I<00:20:41.039> think<00:20:41.240> there's<00:20:41.520> like<00:20:41.640> a<00:20:42.000> pointer 00:20:42.789 --> 00:20:42.799 align:start position:0% the top I think there's like a pointer 00:20:42.799 --> 00:20:45.149 align:start position:0% the top I think there's like a pointer yeah<00:20:43.000> if<00:20:43.280> if<00:20:43.360> you<00:20:43.480> look<00:20:43.720> here<00:20:44.280> basically<00:20:45.080> we 00:20:45.149 --> 00:20:45.159 align:start position:0% yeah if if you look here basically we 00:20:45.159 --> 00:20:47.149 align:start position:0% yeah if if you look here basically we are<00:20:45.320> doing<00:20:45.640> something<00:20:46.080> here<00:20:46.400> and<00:20:46.600> then<00:20:46.760> we<00:20:46.880> say 00:20:47.149 --> 00:20:47.159 align:start position:0% are doing something here and then we say 00:20:47.159 --> 00:20:49.710 align:start position:0% are doing something here and then we say okay<00:20:47.520> we<00:20:47.640> want<00:20:47.799> to<00:20:48.000> jump<00:20:48.240> to<00:20:48.440> the<00:20:48.640> success<00:20:49.400> so 00:20:49.710 --> 00:20:49.720 align:start position:0% okay we want to jump to the success so 00:20:49.720 --> 00:20:52.430 align:start position:0% okay we want to jump to the success so we<00:20:49.919> just<00:20:50.159> have<00:20:50.320> to<00:20:50.520> call<00:20:51.159> the<00:20:51.400> label<00:20:51.880> success 00:20:52.430 --> 00:20:52.440 align:start position:0% we just have to call the label success 00:20:52.440 --> 00:20:55.270 align:start position:0% we just have to call the label success and<00:20:52.640> we<00:20:52.760> jump<00:20:53.000> to<00:20:53.240> it<00:20:54.000> and<00:20:54.400> this<00:20:54.600> piece<00:20:54.840> of<00:20:55.000> code 00:20:55.270 --> 00:20:55.280 align:start position:0% and we jump to it and this piece of code 00:20:55.280 --> 00:20:57.590 align:start position:0% and we jump to it and this piece of code will<00:20:55.440> be<00:20:55.840> executed<00:20:56.400> so<00:20:56.600> it's<00:20:57.120> quite 00:20:57.590 --> 00:20:57.600 align:start position:0% will be executed so it's quite 00:20:57.600 --> 00:20:59.110 align:start position:0% will be executed so it's quite straightforward<00:20:58.320> also 00:20:59.110 --> 00:20:59.120 align:start position:0% straightforward also 00:20:59.120 --> 00:21:03.270 align:start position:0% straightforward also so<00:21:00.120> you<00:21:00.280> can<00:21:00.520> also<00:21:00.799> do<00:21:01.000> it<00:21:01.240> with<00:21:01.480> jump<00:21:02.000> e<00:21:02.640> so<00:21:03.159> you 00:21:03.270 --> 00:21:03.280 align:start position:0% so you can also do it with jump e so you 00:21:03.280 --> 00:21:07.549 align:start position:0% so you can also do it with jump e so you can<00:21:03.520> add<00:21:03.799> like<00:21:04.000> a<00:21:04.440> a<00:21:04.799> condition<00:21:05.080> to<00:21:05.360> to<00:21:05.600> this 00:21:07.549 --> 00:21:07.559 align:start position:0% can add like a a condition to to this 00:21:07.559 --> 00:21:10.830 align:start position:0% can add like a a condition to to this jump<00:21:08.559> and<00:21:08.799> then<00:21:09.000> we<00:21:09.159> have<00:21:09.440> functions<00:21:10.440> so 00:21:10.830 --> 00:21:10.840 align:start position:0% jump and then we have functions so 00:21:10.840 --> 00:21:13.909 align:start position:0% jump and then we have functions so functions<00:21:11.600> can<00:21:11.960> have<00:21:12.400> like<00:21:13.000> uh<00:21:13.159> arguments 00:21:13.909 --> 00:21:13.919 align:start position:0% functions can have like uh arguments 00:21:13.919 --> 00:21:17.070 align:start position:0% functions can have like uh arguments that<00:21:14.039> you<00:21:14.159> can<00:21:14.440> pass<00:21:15.000> here<00:21:16.000> and<00:21:16.480> yeah<00:21:16.679> there<00:21:16.799> is 00:21:17.070 --> 00:21:17.080 align:start position:0% that you can pass here and yeah there is 00:21:17.080 --> 00:21:19.549 align:start position:0% that you can pass here and yeah there is one<00:21:17.440> weird<00:21:17.840> thing<00:21:18.200> here<00:21:18.440> so<00:21:18.720> takes<00:21:19.120> and 00:21:19.549 --> 00:21:19.559 align:start position:0% one weird thing here so takes and 00:21:19.559 --> 00:21:22.029 align:start position:0% one weird thing here so takes and returns<00:21:20.320> so<00:21:20.679> this<00:21:20.799> is<00:21:21.039> something<00:21:21.559> that<00:21:21.760> can 00:21:22.029 --> 00:21:22.039 align:start position:0% returns so this is something that can 00:21:22.039 --> 00:21:24.510 align:start position:0% returns so this is something that can help<00:21:22.279> you<00:21:22.559> know<00:21:23.120> what<00:21:23.279> the<00:21:23.480> function<00:21:23.880> is 00:21:24.510 --> 00:21:24.520 align:start position:0% help you know what the function is 00:21:24.520 --> 00:21:27.669 align:start position:0% help you know what the function is expecting<00:21:25.520> um<00:21:25.960> from<00:21:26.159> the<00:21:26.360> stack<00:21:26.960> and<00:21:27.360> what<00:21:27.520> the 00:21:27.669 --> 00:21:27.679 align:start position:0% expecting um from the stack and what the 00:21:27.679 --> 00:21:29.909 align:start position:0% expecting um from the stack and what the function<00:21:28.000> will<00:21:28.240> left<00:21:28.720> into<00:21:28.919> the<00:21:29.080> stack<00:21:29.720> so 00:21:29.909 --> 00:21:29.919 align:start position:0% function will left into the stack so 00:21:29.919 --> 00:21:31.590 align:start position:0% function will left into the stack so basically<00:21:30.400> what<00:21:30.520> is<00:21:30.679> going<00:21:30.880> to<00:21:31.080> happen<00:21:31.400> is 00:21:31.590 --> 00:21:31.600 align:start position:0% basically what is going to happen is 00:21:31.600 --> 00:21:34.350 align:start position:0% basically what is going to happen is that<00:21:31.840> this<00:21:32.279> function<00:21:33.279> uh<00:21:33.440> is<00:21:33.640> expecting<00:21:34.159> like 00:21:34.350 --> 00:21:34.360 align:start position:0% that this function uh is expecting like 00:21:34.360 --> 00:21:38.190 align:start position:0% that this function uh is expecting like three<00:21:35.200> um<00:21:35.600> values<00:21:36.080> in<00:21:36.240> the<00:21:36.440> stack<00:21:37.360> and<00:21:37.679> after 00:21:38.190 --> 00:21:38.200 align:start position:0% three um values in the stack and after 00:21:38.200 --> 00:21:40.669 align:start position:0% three um values in the stack and after its<00:21:38.600> execution<00:21:39.320> it<00:21:39.480> will<00:21:39.720> left<00:21:40.360> uh<00:21:40.440> it<00:21:40.559> will 00:21:40.669 --> 00:21:40.679 align:start position:0% its execution it will left uh it will 00:21:40.679 --> 00:21:43.230 align:start position:0% its execution it will left uh it will leave<00:21:40.960> sorry<00:21:41.360> like<00:21:41.559> one<00:21:42.400> uh 00:21:43.230 --> 00:21:43.240 align:start position:0% leave sorry like one uh 00:21:43.240 --> 00:21:47.230 align:start position:0% leave sorry like one uh value<00:21:44.240> uh<00:21:44.760> in<00:21:45.159> into<00:21:45.440> the<00:21:45.600> stack<00:21:46.320> so<00:21:46.720> as<00:21:46.880> far<00:21:47.080> as 00:21:47.230 --> 00:21:47.240 align:start position:0% value uh in into the stack so as far as 00:21:47.240 --> 00:21:49.750 align:start position:0% value uh in into the stack so as far as I<00:21:47.400> know<00:21:48.320> this<00:21:48.520> is<00:21:48.679> not<00:21:48.960> enforced<00:21:49.480> by<00:21:49.600> the 00:21:49.750 --> 00:21:49.760 align:start position:0% I know this is not enforced by the 00:21:49.760 --> 00:21:51.789 align:start position:0% I know this is not enforced by the compiler<00:21:50.240> but<00:21:50.360> it's<00:21:50.520> more<00:21:50.799> like<00:21:51.279> a<00:21:51.440> way<00:21:51.600> for 00:21:51.789 --> 00:21:51.799 align:start position:0% compiler but it's more like a way for 00:21:51.799 --> 00:21:54.669 align:start position:0% compiler but it's more like a way for you<00:21:51.960> to<00:21:52.240> just<00:21:52.440> like<00:21:52.720> know<00:21:53.720> uh<00:21:54.039> more<00:21:54.240> or<00:21:54.440> less 00:21:54.669 --> 00:21:54.679 align:start position:0% you to just like know uh more or less 00:21:54.679 --> 00:21:56.830 align:start position:0% you to just like know uh more or less what<00:21:54.840> you<00:21:54.960> should<00:21:55.279> have<00:21:55.799> how<00:21:55.960> you<00:21:56.080> can<00:21:56.279> manage 00:21:56.830 --> 00:21:56.840 align:start position:0% what you should have how you can manage 00:21:56.840 --> 00:21:59.710 align:start position:0% what you should have how you can manage the<00:21:57.039> the<00:21:57.200> stack 00:21:59.710 --> 00:21:59.720 align:start position:0% the the stack 00:21:59.720 --> 00:22:02.350 align:start position:0% the the stack and<00:22:00.120> yeah<00:22:00.279> so<00:22:00.520> basically<00:22:01.080> functions<00:22:02.000> so<00:22:02.200> we 00:22:02.350 --> 00:22:02.360 align:start position:0% and yeah so basically functions so we 00:22:02.360 --> 00:22:04.590 align:start position:0% and yeah so basically functions so we have<00:22:02.559> functions<00:22:03.120> and<00:22:03.320> macros<00:22:04.120> and<00:22:04.279> like<00:22:04.480> the 00:22:04.590 --> 00:22:04.600 align:start position:0% have functions and macros and like the 00:22:04.600 --> 00:22:08.149 align:start position:0% have functions and macros and like the big<00:22:04.840> differen<00:22:05.279> is<00:22:06.039> uh<00:22:06.320> that<00:22:06.760> functions<00:22:07.760> they 00:22:08.149 --> 00:22:08.159 align:start position:0% big differen is uh that functions they 00:22:08.159 --> 00:22:12.390 align:start position:0% big differen is uh that functions they are<00:22:09.159> um<00:22:09.559> copied<00:22:10.039> only<00:22:10.600> once<00:22:11.600> uh<00:22:11.799> the<00:22:11.960> compiler 00:22:12.390 --> 00:22:12.400 align:start position:0% are um copied only once uh the compiler 00:22:12.400 --> 00:22:13.789 align:start position:0% are um copied only once uh the compiler is<00:22:12.520> going<00:22:12.679> to<00:22:12.840> take<00:22:13.039> the<00:22:13.159> code<00:22:13.440> of<00:22:13.559> your 00:22:13.789 --> 00:22:13.799 align:start position:0% is going to take the code of your 00:22:13.799 --> 00:22:15.789 align:start position:0% is going to take the code of your function<00:22:14.400> and<00:22:14.600> it's<00:22:14.760> just<00:22:14.919> going<00:22:15.120> to<00:22:15.360> put<00:22:15.520> it 00:22:15.789 --> 00:22:15.799 align:start position:0% function and it's just going to put it 00:22:15.799 --> 00:22:18.990 align:start position:0% function and it's just going to put it at<00:22:16.000> the<00:22:16.159> end<00:22:16.919> of<00:22:17.360> uh<00:22:17.520> all<00:22:17.799> the<00:22:18.000> the<00:22:18.159> bite<00:22:18.440> code 00:22:18.990 --> 00:22:19.000 align:start position:0% at the end of uh all the the bite code 00:22:19.000 --> 00:22:20.710 align:start position:0% at the end of uh all the the bite code and<00:22:19.279> whenever<00:22:19.640> you're<00:22:19.880> going<00:22:20.080> to<00:22:20.279> call<00:22:20.559> a 00:22:20.710 --> 00:22:20.720 align:start position:0% and whenever you're going to call a 00:22:20.720 --> 00:22:24.070 align:start position:0% and whenever you're going to call a function<00:22:21.600> then<00:22:22.440> um<00:22:22.960> in<00:22:23.159> the<00:22:23.400> execution<00:22:23.919> of 00:22:24.070 --> 00:22:24.080 align:start position:0% function then um in the execution of 00:22:24.080 --> 00:22:26.830 align:start position:0% function then um in the execution of your<00:22:24.240> code<00:22:24.840> it's<00:22:25.159> going<00:22:25.440> to<00:22:25.880> jump<00:22:26.200> to<00:22:26.520> the 00:22:26.830 --> 00:22:26.840 align:start position:0% your code it's going to jump to the 00:22:26.840 --> 00:22:28.750 align:start position:0% your code it's going to jump to the where<00:22:27.080> the<00:22:27.240> function<00:22:27.720> is<00:22:28.240> and<00:22:28.520> when<00:22:28.679> the 00:22:28.750 --> 00:22:28.760 align:start position:0% where

is different from macros in the<00:22:37.480> case<00:22:37.640> of<00:22:37.840> macros<00:22:38.400> what<00:22:38.520> is<00:22:38.640> going<00:22:38.799> to 00:22:38.990 --> 00:22:39.000 align:start position:0% the case of macros what is going to 00:22:39.000 --> 00:22:41.710 align:start position:0% the case of macros what is going to happen<00:22:39.679> every<00:22:39.960> time<00:22:40.120> you're<00:22:40.400> going<00:22:40.720> to<00:22:41.200> invoke 00:22:41.710 --> 00:22:41.720 align:start position:0% happen every time you're going to invoke 00:22:41.720 --> 00:22:44.470 align:start position:0% happen every time you're going to invoke this<00:22:41.880> macro<00:22:42.720> then<00:22:42.919> the<00:22:43.120> compiler<00:22:43.760> is<00:22:43.919> going<00:22:44.120> to 00:22:44.470 --> 00:22:44.480 align:start position:0% this macro then the compiler is going to 00:22:44.480 --> 00:22:47.990 align:start position:0% this macro then the compiler is going to copy<00:22:45.120> the<00:22:45.279> old<00:22:45.600> code<00:22:46.080> and<00:22:46.520> directly<00:22:47.000> put<00:22:47.200> it<00:22:47.559> in 00:22:47.990 --> 00:22:48.000 align:start position:0% copy the old code and directly put it in 00:22:48.000 --> 00:22:51.110 align:start position:0% copy the old code and directly put it in your<00:22:48.320> bite<00:22:48.640> code<00:22:49.520> uh<00:22:49.720> what<00:22:49.919> was<00:22:50.120> compiled<00:22:50.880> so 00:22:51.110 --> 00:22:51.120 align:start position:0% your bite code uh what was compiled so 00:22:51.120 --> 00:22:52.590 align:start position:0% your bite code uh what was compiled so this<00:22:51.240> means<00:22:51.480> that<00:22:51.679> if<00:22:51.760> you're<00:22:52.000> using<00:22:52.320> like 00:22:52.590 --> 00:22:52.600 align:start position:0% this means that if you're using like 00:22:52.600 --> 00:22:54.669 align:start position:0% this means that if you're using like macros<00:22:53.400> then<00:22:53.559> the<00:22:53.799> size<00:22:54.039> of<00:22:54.159> your<00:22:54.360> smart 00:22:54.669 --> 00:22:54.679 align:start position:0% macros then the size of your smart 00:22:54.679 --> 00:22:57.310 align:start position:0% macros then the size of your smart contract<00:22:55.120> might<00:22:55.279> be<00:22:55.440> a<00:22:55.600> bit<00:22:55.840> larger<00:22:56.799> but<00:22:57.120> might 00:22:57.310 --> 00:22:57.320 align:start position:0% contract might be a bit larger but might 00:22:57.320 --> 00:23:00.269 align:start position:0% contract might be a bit larger but might be<00:22:57.840> cheaper<00:22:58.640> guys<00:22:58.960> wise<00:22:59.360> because<00:22:59.640> you<00:22:59.840> will<00:23:00.039> be 00:23:00.269 --> 00:23:00.279 align:start position:0% be cheaper guys wise because you will be 00:23:00.279 --> 00:23:02.390 align:start position:0% be cheaper guys wise because you will be like<00:23:00.520> avoiding<00:23:01.039> like<00:23:01.200> jumping<00:23:01.640> around<00:23:02.240> back 00:23:02.390 --> 00:23:02.400 align:start position:0% like avoiding like jumping around back 00:23:02.400 --> 00:23:03.830 align:start position:0% like avoiding like jumping around back and 00:23:03.830 --> 00:23:03.840 align:start position:0% and 00:23:03.840 --> 00:23:07.789 align:start position:0% and forth<00:23:04.840> and<00:23:05.080> also<00:23:05.400> by<00:23:05.559> the<00:23:05.679> way<00:23:05.960> yeah<00:23:06.240> so<00:23:07.240> uh<00:23:07.679> we 00:23:07.789 --> 00:23:07.799 align:start position:0% forth and also by the way yeah so uh we 00:23:07.799 --> 00:23:09.710 align:start position:0% forth and also by the way yeah so uh we don't<00:23:08.039> have<00:23:08.159> it<00:23:08.360> here<00:23:08.559> but<00:23:08.760> basically<00:23:09.159> macros 00:23:09.710 --> 00:23:09.720 align:start position:0% don't have it here but basically macros 00:23:09.720 --> 00:23:12.149 align:start position:0% don't have it here but basically macros they<00:23:09.960> accept<00:23:10.320> like<00:23:10.640> parameters<00:23:11.640> and<00:23:11.799> you<00:23:11.960> have 00:23:12.149 --> 00:23:12.159 align:start position:0% they accept like parameters and you have 00:23:12.159 --> 00:23:16.190 align:start position:0% they accept like parameters and you have also<00:23:12.440> the<00:23:12.600> takes<00:23:12.919> and<00:23:13.279> returns<00:23:13.960> uh 00:23:16.190 --> 00:23:16.200 align:start position:0% also the takes and returns uh 00:23:16.200 --> 00:23:19.070 align:start position:0% also the takes and returns uh indications<00:23:17.200> so<00:23:17.440> we<00:23:17.559> have<00:23:17.760> like<00:23:18.080> two 00:23:19.070 --> 00:23:19.080 align:start position:0% indications so we have like two 00:23:19.080 --> 00:23:21.710 align:start position:0% indications so we have like two important<00:23:19.880> macros<00:23:20.520> that<00:23:20.640> you<00:23:20.760> need<00:23:20.960> to<00:23:21.120> know 00:23:21.710 --> 00:23:21.720 align:start position:0% important macros that you need to know 00:23:21.720 --> 00:23:22.870 align:start position:0% important macros that you need to know we<00:23:21.840> have<00:23:22.080> the 00:23:22.870 --> 00:23:22.880 align:start position:0% we have the 00:23:22.880 --> 00:23:25.230 align:start position:0% we have the Constructor<00:23:23.880> it<00:23:24.039> works<00:23:24.360> the<00:23:24.480> same<00:23:24.720> way<00:23:25.000> as 00:23:25.230 --> 00:23:25.240 align:start position:0% Constructor it works the same way as 00:23:25.240 --> 00:23:27.789 align:start position:0% Constructor it works the same way as solidity<00:23:25.960> actually<00:23:26.600> so<00:23:26.880> basically<00:23:27.559> if<00:23:27.640> you 00:23:27.789 --> 00:23:27.799 align:start position:0% solidity actually so basically if you 00:23:27.799 --> 00:23:29.990 align:start position:0% solidity actually so basically if you want<00:23:28.000> to<00:23:28.159> ex<00:23:28.720> some<00:23:28.919> code<00:23:29.559> uh<00:23:29.640> when<00:23:29.760> you're 00:23:29.990 --> 00:23:30.000 align:start position:0% want to ex some code uh when you're 00:23:30.000 --> 00:23:31.669 align:start position:0% want to ex some code uh when you're deploying<00:23:30.440> your<00:23:30.679> contract<00:23:31.200> then<00:23:31.320> you<00:23:31.480> just 00:23:31.669 --> 00:23:31.679 align:start position:0% deploying your contract then you just 00:23:31.679 --> 00:23:35.190 align:start position:0% deploying your contract then you just have<00:23:31.799> to<00:23:32.039> put<00:23:32.200> it<00:23:32.400> into<00:23:32.760> the<00:23:33.440> Constructor<00:23:34.440> um 00:23:35.190 --> 00:23:35.200 align:start position:0% have to put it into the Constructor um 00:23:35.200 --> 00:23:38.430 align:start position:0% have to put it into the Constructor um and<00:23:35.400> we<00:23:35.559> have<00:23:35.840> the<00:23:36.480> main<00:23:37.240> macro<00:23:38.080> the<00:23:38.200> main 00:23:38.430 --> 00:23:38.440 align:start position:0% and we have the main macro the main 00:23:38.440 --> 00:23:41.149 align:start position:0% and we have the main macro the main macro<00:23:38.880> is<00:23:39.360> uh<00:23:39.679> well<00:23:39.919> quite<00:23:40.200> simple<00:23:40.840> this<00:23:40.960> is 00:23:41.149 --> 00:23:41.159 align:start position:0% macro is uh well quite simple this is 00:23:41.159 --> 00:23:43.110 align:start position:0% macro is uh well quite simple this is like<00:23:41.440> the<00:23:41.679> entry<00:23:42.080> point<00:23:42.400> of<00:23:42.520> your<00:23:42.720> smart 00:23:43.110 --> 00:23:43.120 align:start position:0% like the entry point of your smart 00:23:43.120 --> 00:23:45.230 align:start position:0% like the entry point of your smart contract<00:23:43.840> so<00:23:44.080> whenever<00:23:44.480> someone<00:23:44.760> is<00:23:44.880> going<00:23:45.039> to 00:23:45.230 --> 00:23:45.240 align:start position:0% contract so whenever someone is going to 00:23:45.240 --> 00:23:46.630 align:start position:0% contract so whenever someone is going to call<00:23:45.480> your<00:23:45.679> smart 00:23:46.630 --> 00:23:46.640 align:start position:0% call your smart 00:23:46.640 --> 00:23:49.549 align:start position:0% call your smart contract<00:23:47.640> Dom<00:23:47.799> main<00:23:48.039> macro<00:23:48.400> will<00:23:48.559> be<00:23:48.720> executed 00:23:49.549 --> 00:23:49.559 align:start position:0% contract Dom main macro will be executed 00:23:49.559 --> 00:23:52.029 align:start position:0% contract Dom main macro will be executed so<00:23:49.799> this<00:23:49.919> is<00:23:50.200> where<00:23:50.520> you<00:23:50.640> want<00:23:50.840> to<00:23:51.039> do<00:23:51.279> like<00:23:51.600> a 00:23:52.029 --> 00:23:52.039 align:start position:0% so this is where you want to do like a 00:23:52.039 --> 00:23:54.630 align:start position:0% so this is where you want to do like a the<00:23:52.240> function<00:23:53.240> uh<00:23:53.400> dispatching<00:23:54.159> or<00:23:54.360> things 00:23:54.630 --> 00:23:54.640 align:start position:0% the function uh dispatching or things 00:23:54.640 --> 00:23:56.510 align:start position:0% the function uh dispatching or things like<00:23:54.799> that<00:23:55.039> but<00:23:55.240> we<00:23:55.400> we're<00:23:55.600> going<00:23:55.760> to<00:23:55.919> see<00:23:56.200> that 00:23:56.510 --> 00:23:56.520 align:start position:0% like that but we we're going to see that 00:23:56.520 --> 00:23:58.909 align:start position:0% like that but we we're going to see that in<00:23:56.679> a<00:23:56.880> in<00:23:56.960> a<00:23:57.120> minute 00:23:58.909 --> 00:23:58.919 align:start position:0% in a in a minute 00:23:58.919 --> 00:24:01.710 align:start position:0% in a in a minute uh<00:23:59.039> we<00:23:59.200> have<00:23:59.360> jump<00:23:59.720> tables<00:24:00.279> so<00:24:00.760> it's<00:24:01.360> pretty 00:24:01.710 --> 00:24:01.720 align:start position:0% uh we have jump tables so it's pretty 00:24:01.720 --> 00:24:04.789 align:start position:0% uh we have jump tables so it's pretty small<00:24:02.320> and<00:24:02.600> a<00:24:02.720> bit<00:24:03.120> long<00:24:03.600> so<00:24:04.159> yeah<00:24:04.400> just<00:24:04.520> a<00:24:04.679> way 00:24:04.789 --> 00:24:04.799 align:start position:0% small and a bit long so yeah just a way 00:24:04.799 --> 00:24:09.830 align:start position:0% small and a bit long so yeah just a way to<00:24:04.919> do<00:24:05.159> like<00:24:05.520> um<00:24:06.200> um<00:24:07.000> switch<00:24:08.000> statements<00:24:09.000> uh<00:24:09.279> in 00:24:09.830 --> 00:24:09.840 align:start position:0% to do like um um switch statements uh in 00:24:09.840 --> 00:24:13.789 align:start position:0% to do like um um switch statements uh in half<00:24:10.440> so<00:24:10.679> maybe<00:24:11.039> we<00:24:11.679> can<00:24:11.880> see<00:24:12.200> that<00:24:12.440> a<00:24:12.600> bit 00:24:13.789 --> 00:24:13.799 align:start position:0% half so maybe we can see that a bit 00:24:13.799 --> 00:24:17.029 align:start position:0% half so maybe we can see that a bit later<00:24:14.799> so<00:24:15.279> yeah<00:24:15.600> let's<00:24:15.880> code<00:24:16.279> so<00:24:16.600> I<00:24:16.679> think<00:24:16.840> it's 00:24:17.029 --> 00:24:17.039 align:start position:0% later so yeah let's code so I think it's 00:24:17.039 --> 00:24:20.909 align:start position:0% later so yeah let's code so I think it's time<00:24:17.279> now<00:24:17.480> to<00:24:17.840> write<00:24:18.080> some<00:24:18.400> actual<00:24:18.799> code<00:24:19.919> so 00:24:20.909 --> 00:24:20.919 align:start position:0% time now to write some actual code so 00:24:20.919 --> 00:24:24.110 align:start position:0% time now to write some actual code so yeah<00:24:21.279> we<00:24:21.559> need<00:24:22.320> uh<00:24:22.600> I<00:24:22.720> hope<00:24:22.960> like<00:24:23.440> you<00:24:23.679> guys<00:24:23.880> all 00:24:24.110 --> 00:24:24.120 align:start position:0% yeah we need uh I hope like you guys all 00:24:24.120 --> 00:24:26.789 align:start position:0% yeah we need uh I hope like you guys all have<00:24:24.279> a<00:24:24.480> laptop<00:24:25.279> otherwise<00:24:26.159>

position:0% have a laptop otherwise it's going to be a<00:24:26.919> bit<00:24:27.080> boring<00:24:27.360> for<00:24:27.559> you<00:24:27.760> I'm<00:24:27.919> sorry<00:24:28.640> so<00:24:29.000> we<00:24:29.159> are 00:24:29.470 --> 00:24:29.480 align:start position:0% a bit boring for you I'm sorry so we are 00:24:29.480 --> 00:24:31.870 align:start position:0% a bit boring for you I'm sorry so we are going<00:24:29.720> to<00:24:30.000> write<00:24:30.240> some<00:24:30.480> code<00:24:31.320> uh<00:24:31.440> we<00:24:31.559> are<00:24:31.720> going 00:24:31.870 --> 00:24:31.880 align:start position:0% going to write some code uh we are going 00:24:31.880 --> 00:24:34.549 align:start position:0% going to write some code uh we are going to<00:24:32.080> use<00:24:32.559> the<00:24:32.919> template<00:24:33.399> that<00:24:33.520> is<00:24:33.679> using 00:24:34.549 --> 00:24:34.559 align:start position:0% to use the template that is using 00:24:34.559 --> 00:24:36.870 align:start position:0% to use the template that is using Foundry<00:24:35.559> so<00:24:35.760> if<00:24:35.840> you<00:24:35.960> don't<00:24:36.159> have<00:24:36.360> Foundry<00:24:36.799> you 00:24:36.870 --> 00:24:36.880 align:start position:0% Foundry so if you don't have Foundry you 00:24:36.880 --> 00:24:40.310 align:start position:0% Foundry so if you don't have Foundry you can<00:24:37.120> install<00:24:37.520> it<00:24:38.159> uh<00:24:38.279> using<00:24:38.679> this 00:24:40.310 --> 00:24:40.320 align:start position:0% can install it uh using this 00:24:40.320 --> 00:24:42.830 align:start position:0% can install it uh using this commands<00:24:41.320> I'll<00:24:41.520> just<00:24:41.679> give<00:24:41.799> you<00:24:41.960> like<00:24:42.080> a<00:24:42.240> few 00:24:42.830 --> 00:24:42.840 align:start position:0% commands I'll just give you like a few 00:24:42.840 --> 00:25:15.830 align:start position:0% commands I'll just give you like a few minutes<00:24:43.279> to<00:24:43.880> start<00:24:44.240> installing<00:24:44.760> stuff 00:25:15.830 --> 00:25:15.840 align:start position:0% 00:25:15.840 --> 00:25:18.230 align:start position:0% so<00:25:16.120> if<00:25:16.240> you<00:25:16.440> already<00:25:16.799> have<00:25:17.000> Foundry<00:25:17.799> you<00:25:17.919> can 00:25:18.230 --> 00:25:18.240 align:start position:0% so if you already have Foundry you can 00:25:18.240 --> 00:25:21.430 align:start position:0% so if you already have Foundry you can install<00:25:19.159> directly<00:25:20.159> uh<00:25:20.480> have<00:25:20.960> like<00:25:21.159> this<00:25:21.240> is 00:25:21.430 --> 00:25:21.440 align:start position:0% install directly uh have like this is 00:25:21.440 --> 00:25:22.470 align:start position:0% install directly uh have like this is like 00:25:22.470 --> 00:25:22.480 align:start position:0% like 00:25:22.480 --> 00:25:26.389 align:start position:0% like the<00:25:23.480> version<00:25:24.039> manager<00:25:24.840> I<00:25:24.919> would<00:25:25.159> say<00:25:25.919> so<00:25:26.320> you 00:25:26.389 --> 00:25:26.399 align:start position:0% the version manager I would say so you 00:25:26.399 --> 00:25:29.470 align:start position:0% the version manager I would say so you can<00:25:26.600> run<00:25:26.960> this<00:25:28.440> maybe<00:25:28.679> I<00:25:28.760> should<00:25:28.960> have<00:25:29.200> put 00:25:29.470 --> 00:25:29.480 align:start position:0% can run this maybe I should have put 00:25:29.480 --> 00:25:33.710 align:start position:0% can run this maybe I should have put this<00:25:29.760> two<00:25:30.159> into<00:25:30.399> the<00:25:30.559> same<00:25:30.799> slide<00:25:31.200> I'm 00:25:33.710 --> 00:25:33.720 align:start position:0%

00:27:47.669 --> 00:27:47.679 align:start position:0% if you guys have Foundry we can move 00:27:47.679 --> 00:27:50.549 align:start position:0% if you guys have Foundry we can move forward<00:27:48.640> uh<00:27:48.799> then<00:27:48.919> you<00:27:49.120> just<00:27:49.240> need<00:27:49.399> to<00:27:49.640> install 00:27:50.549 --> 00:27:50.559 align:start position:0% forward uh then you just need to install 00:27:50.559 --> 00:27:54.350 align:start position:0% forward uh then you just need to install half<00:27:51.559> and<00:27:51.799> once<00:27:52.159> you've<00:27:52.519> done<00:27:53.039> this<00:27:54.039> uh<00:27:54.200> you 00:27:54.350 --> 00:27:54.360 align:start position:0% half and once you've done this uh you 00:27:54.360 --> 00:27:57.830 align:start position:0% half and once you've done this uh you can<00:27:55.120> install<00:27:56.120> uh<00:27:56.240> so<00:27:56.760> this<00:27:56.880> is<00:27:57.120> installing<00:27:57.679> the 00:27:57.830 --> 00:27:57.840 align:start position:0% can install uh so this is installing the 00:27:57.840 --> 00:28:00.070 align:start position:0% can install uh so this is installing the packet<00:27:58.559> manager<00:27:58.960> not<00:27:59.080> the<00:27:59.240> package<00:27:59.600> sorry<00:27:59.919> the 00:28:00.070 --> 00:28:00.080 align:start position:0%

there is also<00:32:41.559> debugger<00:32:42.200> but<00:32:42.559> we're<00:32:42.720> not<00:32:42.880> going<00:32:43.080> to<00:32:43.200> use 00:32:43.430 --> 00:32:43.440 align:start position:0% also debugger but we're not going to use 00:32:43.440 --> 00:32:46.470 align:start position:0% also debugger but we're not going to use that<00:32:44.080> today<00:32:45.080> so<00:32:45.399> yeah<00:32:45.600> just<00:32:45.720> let<00:32:45.880> me<00:32:46.039> know<00:32:46.200> if 00:32:46.470 --> 00:32:46.480 align:start position:0% that today so yeah just let me

I'm<00:32:49.919> relieved 00:33:07.629 --> 00:33:07.639 align:start position:0% 00:33:07.639 --> 00:33:10.509 align:start position:0% nice<00:33:08.639> uh<00:33:08.840> it<00:33:08.960> should<00:33:09.200> be<00:33:09.559> so<00:33:09.799> do<00:33:09.919> you<00:33:10.000> have<00:33:10.200> vs 00:33:10.509 --> 00:33:10.519 align:start position:0% nice uh it should be so do you have vs 00:33:10.519 --> 00:33:14.350 align:start position:0% nice uh it should be so do you have vs code<00:33:11.320> if<00:33:11.440> you<00:33:11.760> open<00:33:12.399> the<00:33:12.760> repo<00:33:13.559> in<00:33:13.799> vs<00:33:14.080> code<00:33:14.279> it 00:33:14.350 --> 00:33:14.360 align:start position:0% code if you open the repo in vs code it 00:33:14.360 --> 00:33:17.110 align:start position:0% code if you open the repo in vs code it should<00:33:14.799> like<00:33:15.039> pop<00:33:15.240> up<00:33:15.600> the<00:33:16.240> suggested 00:33:17.110 --> 00:33:17.120 align:start position:0% should like pop up the suggested 00:33:17.120 --> 00:33:19.110 align:start position:0% should like pop up the suggested extension<00:33:17.919> other<00:33:18.320> otherwise<00:33:18.720> it's<00:33:18.880> called 00:33:19.110 --> 00:33:19.120 align:start position:0% extension other otherwise it's called 00:33:19.120 --> 00:33:22.870 align:start position:0% extension other otherwise it's called like<00:33:19.320> half<00:33:19.679> language<00:33:20.279> I 00:33:22.870 --> 00:33:22.880 align:start position:0% 00:33:22.880 --> 00:33:26.470 align:start position:0% think<00:33:23.880> you<00:33:24.080> got<00:33:24.240> it 00:33:26.470 --> 00:33:26.480 align:start position:0% think you got it 00:33:26.480 --> 00:33:28.830 align:start position:0% think you got it perfect<00:33:27.480> yeah<00:33:27.840> it<00:33:27.919> would<00:33:28.080> be<00:33:28.240> better<00:33:28.519> to<00:33:28.679> be 00:33:28.830 --> 00:33:28.840 align:start position:0% perfect yeah it would be better to be 00:33:28.840 --> 00:33:32.190 align:start position:0% perfect yeah it would be better to be using<00:33:29.320> some<00:33:29.919> having<00:33:30.200> some<00:33:30.480> colors<00:33:31.200> otherwise 00:33:32.190 --> 00:33:32.200 align:start position:0% using some having some colors otherwise 00:33:32.200 --> 00:33:33.990 align:start position:0% using some having some colors otherwise it's<00:33:32.360> going<00:33:32.600> to<00:33:32.760> be<00:33:32.880> a<00:33:33.000> bit<00:33:33.200> hard<00:33:33.399> just<00:33:33.559> to<00:33:33.720> see 00:33:33.990 --> 00:33:34.000 align:start position:0% it's going to be a bit hard just to see 00:33:34.000 --> 00:33:37.830 align:start position:0% it's going to be a bit hard just to see what<00:33:34.559> what<00:33:34.679> we're<00:33:35.399> doing<00:33:36.399> uh<00:33:37.159> yeah<00:33:37.519> I'll<00:33:37.639> just 00:33:37.830 --> 00:33:37.840 align:start position:0% what what we're doing uh yeah I'll just 00:33:37.840 --> 00:33:39.389 align:start position:0% what what we're doing uh yeah I'll just give<00:33:37.960> you<00:33:38.080> a<00:33:38.159> few<00:33:38.360> minutes<00:33:38.760> because<00:33:39.080> I<00:33:39.159> think 00:33:39.389 --> 00:33:39.399 align:start position:0% give you a few minutes because I think 00:33:39.399 --> 00:33:42.149 align:start position:0% give you a few minutes because I think the<00:33:39.639> slide<00:33:40.039> just<00:33:40.320> after<00:33:40.639> this<00:33:41.480> yeah<00:33:41.919> like 00:33:42.149 --> 00:33:42.159 align:start position:0% the slide just after this yeah like 00:33:42.159 --> 00:33:43.549 align:start position:0% the slide just after this yeah like after<00:33:42.440> this<00:33:42.559> we're<00:33:42.799> just<00:33:42.919> going<00:33:43.120> to<00:33:43.279> be 00:33:43.549 --> 00:33:43.559 align:start position:0% after this we're just going to be 00:33:43.559 --> 00:33:46.830 align:start position:0% after this we're just going to be cooking<00:33:44.519> so<00:33:45.000> I<00:33:45.120> just<00:33:45.240> want<00:33:45.440> to<00:33:45.639> be<00:33:46.279> sure<00:33:46.600> that 00:33:46.830 --> 00:33:46.840 align:start position:0% cooking so I just want to be sure that 00:33:46.840 --> 00:34:11.190 align:start position:0% cooking so I just want to be sure that everyone<00:33:47.240> can<00:33:47.440> follow 00:34:11.190 --> 00:34:11.200 align:start position:0% 00:34:11.200 --> 00:34:36.349 align:start position:0% right<00:34:11.839> exion 00:34:36.349 --> 00:34:36.359 align:start position:0% 00:34:36.359 --> 00:34:40.710 align:start position:0% okay<00:34:36.879> good<00:34:37.480> yeah<00:34:37.639> it<00:34:37.760> looks<00:34:38.280> like<00:34:39.280> we<00:34:39.480> are<00:34:39.879> all 00:34:40.710 --> 00:34:40.720 align:start position:0% okay good yeah it looks like we are all 00:34:40.720 --> 00:34:44.389 align:start position:0% okay good yeah it looks like we are all set<00:34:41.720> so<00:34:42.399> what<00:34:42.839> we<00:34:43.079> are<00:34:43.399> going<00:34:43.760> to<00:34:43.919> do<00:34:44.200> we<00:34:44.280> are 00:34:44.389 --> 00:34:44.399 align:start position:0% set so what we are going to do we are 00:34:44.399 --> 00:34:46.829 align:start position:0% set so what we are going to do we are going<00:34:44.599> to<00:34:44.720> be<00:34:44.839> writing<00:34:45.240> our<00:34:45.679> first<00:34:46.480> half 00:34:46.829 --> 00:34:46.839 align:start position:0% going to be writing our first half 00:34:46.839 --> 00:34:49.909 align:start position:0% going to be writing our first half contract<00:34:47.760> so<00:34:48.159> I<00:34:48.240> think<00:34:48.480> there<00:34:48.599> might<00:34:48.839> be<00:34:49.040> a 00:34:49.909 --> 00:34:49.919 align:start position:0% contract so I think there might be a 00:34:49.919 --> 00:34:53.629 align:start position:0% contract so I think there might be a source<00:34:50.919> uh<00:34:51.159> folder<00:34:51.879> if<00:34:52.800> maybe<00:34:53.040> it's<00:34:53.200> not<00:34:53.440> there 00:34:53.629 --> 00:34:53.639 align:start position:0% source uh folder if maybe it's not there 00:34:53.639 --> 00:34:55.230 align:start position:0% source uh folder if maybe it's not there anymore<00:34:54.040> I<00:34:54.119> don't<00:34:54.280> know<00:34:54.679> but<00:34:54.800> you<00:34:54.879> can<00:34:55.079> just 00:34:55.230 --> 00:34:55.240 align:start position:0% anymore I don't know but you can just 00:34:55.240 --> 00:34:59.030 align:start position:0% anymore I don't know but you can just make<00:34:55.520> like<00:34:55.679> a<00:34:55.960> CR<00:34:56.679> um<00:34:56.879> Sr<00:34:57.359> C<00:34:57.760> folder<00:34:58.760> then<00:34:58.880> you 00:34:59.030 --> 00:34:59.040 align:start position:0% make like a CR um Sr C folder then you 00:34:59.040 --> 00:35:02.390 align:start position:0% make like a CR um Sr C folder then you can<00:34:59.359> write<00:34:59.640> the<00:35:00.079> first<00:35:01.079> uh<00:35:01.800> like<00:35:01.960> create<00:35:02.280> the 00:35:02.390 --> 00:35:02.400 align:start position:0% can write the first uh like create the 00:35:02.400 --> 00:35:04.950 align:start position:0% can write the first uh like create the first<00:35:02.720> file<00:35:03.079> you<00:35:03.200> can<00:35:03.480> name<00:35:03.720> it<00:35:04.560> the<00:35:04.680> way<00:35:04.839> you 00:35:04.950 --> 00:35:04.960 align:start position:0% first file you can name it the way you 00:35:04.960 --> 00:35:08.750 align:start position:0% first file you can name it the way you want<00:35:05.280> compute.<00:35:06.160> half<00:35:07.000> or<00:35:07.680> whatever<00:35:08.040> you<00:35:08.200> want 00:35:08.750 --> 00:35:08.760 align:start position:0% want compute. half or whatever you want 00:35:08.760 --> 00:35:13.150 align:start position:0% want compute. half or whatever you want and<00:35:09.079> then<00:35:09.280> we<00:35:09.440> are<00:35:09.680> going<00:35:09.960> to<00:35:10.280> be<00:35:11.280> writing<00:35:11.680> some 00:35:13.150 --> 00:35:13.160 align:start position:0% and then we are going to be writing some 00:35:13.160 --> 00:35:16.190 align:start position:0% and then we are going to be writing some code<00:35:14.160> so<00:35:14.560> this<00:35:14.680> is<00:35:14.800> the<00:35:15.000> first<00:35:15.280> contract<00:35:16.000> we 00:35:16.190 --> 00:35:16.200 align:start position:0% code so this is the first contract we 00:35:16.200 --> 00:35:20.790 align:start position:0% code so this is the first contract we are<00:35:16.640> going<00:35:16.960> to<00:35:17.200> be<00:35:17.880> writing<00:35:18.520> today<00:35:19.520> it's<00:35:20.079> uh 00:35:20.790 --> 00:35:20.800 align:start position:0% are going to be writing today it's uh 00:35:20.800 --> 00:35:23.790 align:start position:0% are going to be writing today it's uh extremely<00:35:21.800> complicated<00:35:22.520> you<00:35:22.640> will<00:35:22.839> see<00:35:23.560> this 00:35:23.790 --> 00:35:23.800 align:start position:0% extremely complicated you will see this 00:35:23.800 --> 00:35:26.670 align:start position:0% extremely complicated you will see this construct<00:35:24.480> is<00:35:24.720> just<00:35:24.920> going<00:35:25.200> to<00:35:26.119> take<00:35:26.400> two 00:35:26.670 --> 00:35:26.680 align:start position:0% construct is just going to take two 00:35:26.680 --> 00:35:30.349 align:start position:0% construct is just going to take two values<00:35:27.960> and<00:35:28.240> multiply<00:35:29.119> uh<00:35:29.359> yeah<00:35:29.800> no<00:35:30.119> not 00:35:30.349 --> 00:35:30.359 align:start position:0% values and multiply uh yeah no not 00:35:30.359 --> 00:35:32.750 align:start position:0% values and multiply uh yeah no not multiply<00:35:31.000> actually<00:35:31.599> add<00:35:31.839> these<00:35:32.079> values 00:35:32.750 --> 00:35:32.760 align:start position:0% multiply actually add these values 00:35:32.760 --> 00:35:35.270 align:start position:0% multiply actually add these values together<00:35:33.760> and<00:35:34.079> then<00:35:34.320> just<00:35:34.480> going<00:35:34.680> to<00:35:35.000> return 00:35:35.270 --> 00:35:35.280 align:start position:0% together and then just going to return 00:35:35.280 --> 00:35:38.310 align:start position:0% together and then just going to return them<00:35:35.680> so<00:35:36.000> as<00:35:36.079> you<00:35:36.200> can<00:35:36.400> see<00:35:36.599> it's<00:35:37.320> extremely 00:35:38.310 --> 00:35:38.320 align:start position:0% them so as you can see it's extremely 00:35:38.320 --> 00:35:42.829 align:start position:0% them so as you can see it's extremely hard<00:35:38.800> to<00:35:39.880> understand<00:35:40.880> um<00:35:41.640> yeah<00:35:41.880> so<00:35:42.200> let's<00:35:42.560> just 00:35:42.829 --> 00:35:42.839 align:start position:0% hard to understand um yeah so let's just 00:35:42.839 --> 00:35:45.270 align:start position:0% hard to understand um yeah so let's just like<00:35:43.000> follow<00:35:43.359> along<00:35:43.760> if<00:35:43.880> you<00:35:44.079> guys<00:35:44.320> have<00:35:44.880> your 00:35:45.270 --> 00:35:45.280 align:start position:0% like follow along if you guys have your 00:35:45.280 --> 00:35:47.829 align:start position:0% like follow along if you guys have your setup<00:35:45.839> already<00:35:46.440> you<00:35:46.560> can<00:35:46.880> code<00:35:47.240> at<00:35:47.400> the<00:35:47.599> at<00:35:47.720> the 00:35:47.829 --> 00:35:47.839 align:start position:0% setup already you can code at the at the 00:35:47.839 --> 00:35:50.550 align:start position:0% setup already you can code at the at the same<00:35:48.119> time<00:35:48.800> so<00:35:49.040> the<00:35:49.200> first<00:35:49.400> thing<00:35:49.720> we<00:35:50.160> want<00:35:50.400> to 00:35:50.550 --> 00:35:50.560 align:start position:0% same time so the first thing we want to 00:35:50.560 --> 00:35:53.190 align:start position:0% same time so the first thing we want to do<00:35:50.920> that<00:35:51.359> we<00:35:51.480> are<00:35:51.720> just<00:35:51.920> going<00:35:52.160> to<00:35:52.640> define<00:35:53.000> a 00:35:53.190 --> 00:35:53.200 align:start position:0% do that we are just going to define a 00:35:53.200 --> 00:35:56.230 align:start position:0% do that we are just going to define a function<00:35:53.680> so<00:35:54.040> here<00:35:54.319> as<00:35:54.440> you<00:35:54.560> can<00:35:54.960> see<00:35:55.960> uh<00:35:56.160> this 00:35:56.230 --> 00:35:56.240 align:start position:0% function so here as you can see uh this 00:35:56.240 --> 00:35:58.349 align:start position:0% function so here as you can see uh this is<00:35:56.440> what<00:35:56.560> we're<00:35:56.800> doing<00:35:57.160> here 00:35:58.349 --> 00:35:58.359 align:start position:0% is what we're doing here 00:35:58.359 --> 00:36:00.670 align:start position:0% is what we're doing here let's<00:35:58.599> call<00:35:58.800> it<00:35:59.000> I<00:35:59.160> don't<00:35:59.359> like<00:35:59.760> compute<00:36:00.560> you 00:36:00.670 --> 00:36:00.680 align:start position:0% let's call it I don't like compute you 00:36:00.680 --> 00:36:03.790 align:start position:0% let's call it I don't like compute you can<00:36:00.960> call<00:36:01.200> it<00:36:01.640> ad<00:36:02.040> or<00:36:02.520> whatever<00:36:03.079> just<00:36:03.720> it 00:36:03.790 --> 00:36:03.800 align:start position:0% can call it ad or whatever just it 00:36:03.800 --> 00:36:07.030 align:start position:0% can call it ad or whatever just it doesn't<00:36:04.079> really<00:36:04.400> matter<00:36:05.400> um<00:36:05.960> and<00:36:06.480> so<00:36:06.800> this 00:36:07.030 --> 00:36:07.040 align:start position:0% doesn't really matter um and so this 00:36:07.040 --> 00:36:10.710 align:start position:0% doesn't really matter um and so this function<00:36:08.000> is<00:36:08.200> going<00:36:08.880> to<00:36:09.880> accept<00:36:10.400> two 00:36:10.710 --> 00:36:10.720 align:start position:0% function is going to accept two 00:36:10.720 --> 00:36:15.190 align:start position:0% function is going to accept two parameters<00:36:11.359> so<00:36:11.640> we<00:36:11.800> need<00:36:12.160> like<00:36:12.720> one<00:36:13.160> u<00:36:13.440> in<00:36:14.200> 256 00:36:15.190 --> 00:36:15.200 align:start position:0% parameters so we need like one u in 256 00:36:15.200 --> 00:36:19.150 align:start position:0% parameters so we need like one u in 256 and<00:36:15.880> why<00:36:16.040> not<00:36:16.440> another<00:36:16.920> u<00:36:17.160> in<00:36:17.760> 256<00:36:18.760> and<00:36:19.000> then 00:36:19.150 --> 00:36:19.160 align:start position:0% and why not another u in 256 and then 00:36:19.160 --> 00:36:22.309 align:start position:0% and why not another u in 256 and then it's<00:36:19.359> going<00:36:19.599> to<00:36:20.040> return<00:36:20.640> well<00:36:21.280> something<00:36:21.839> very 00:36:22.309 --> 00:36:22.319 align:start position:0% it's going to return well something very 00:36:22.319 --> 00:36:25.470 align:start position:0% it's going to return well something very original<00:36:23.000> one<00:36:23.319> U<00:36:23.560> went 00:36:25.470 --> 00:36:25.480 align:start position:0% original one U went 00:36:25.480 --> 00:36:29.030 align:start position:0% original one U went 256<00:36:26.480> so<00:36:26.880> this<00:36:27.000> is<00:36:27.200> just<00:36:27.400> like<00:36:27.680> like<00:36:28.599> the 00:36:29.030 --> 00:36:29.040 align:start position:0% 256 so this is just like like the 00:36:29.040 --> 00:36:32.750 align:start position:0% 256 so this is just like like the function<00:36:30.000> that<00:36:30.520> uh<00:36:30.680> we<00:36:31.000> Define<00:36:31.960> and<00:36:32.480> this 00:36:32.750 --> 00:36:32.760 align:start position:0% function that uh we Define and this 00:36:32.760 --> 00:36:36.030 align:start position:0% function that uh we Define and this definition<00:36:33.480> will<00:36:33.680> be<00:36:33.839> used<00:36:34.200> by<00:36:34.560> US<00:36:35.319> inside<00:36:35.800> of 00:36:36.030 --> 00:36:36.040 align:start position:0% definition will be used by US inside of 00:36:36.040 --> 00:36:38.430 align:start position:0% definition will be used by US inside of our<00:36:36.400> have<00:36:36.760> contract<00:36:37.480> but<00:36:37.640> it<00:36:37.760> will<00:36:38.040> also<00:36:38.280> be 00:36:38.430 --> 00:36:38.440 align:start position:0% our have contract but it will also be 00:36:38.440 --> 00:36:41.069 align:start position:0% our have contract but it will also be used<00:36:38.839> by<00:36:39.079> the<00:36:39.280> people<00:36:39.720> that<00:36:39.920> want<00:36:40.160> to<00:36:40.480> interact 00:36:41.069 --> 00:36:41.079 align:start position:0% used by the people that want to interact 00:36:41.079 --> 00:36:42.870 align:start position:0% used by the people that want to interact with<00:36:41.319> our 00:36:42.870 --> 00:36:42.880 align:start position:0% with our 00:36:42.880 --> 00:36:45.990 align:start position:0% with our contracts<00:36:43.880> so<00:36:44.319> then<00:36:44.520> we<00:36:44.680> have<00:36:45.119> this<00:36:45.760> which<00:36:45.880> is 00:36:45.990 --> 00:36:46.000 align:start position:0% contracts so then we have this which is 00:36:46.000 --> 00:36:50.109 align:start position:0% contracts so then we have this which is a<00:36:46.200> macro<00:36:46.800> here<00:36:47.640> that<00:36:47.839> we<00:36:48.000> are<00:36:48.280> calling<00:36:49.119> compute 00:36:50.109 --> 00:36:50.119 align:start position:0% a macro here that we are calling compute 00:36:50.119 --> 00:36:54.190 align:start position:0% a macro here that we are calling compute um<00:36:50.560> so<00:36:50.800> we<00:36:50.920> can<00:36:51.760> Define<00:36:52.280> this<00:36:52.599> macro<00:36:53.160> here<00:36:54.040> just 00:36:54.190 --> 00:36:54.200 align:start position:0% um so we can Define this macro here just 00:36:54.200 --> 00:36:57.589 align:start position:0% um so we can Define this macro here just a<00:36:54.359> way<00:36:54.560> to<00:36:54.839> organize<00:36:55.400> our<00:36:55.720> Cod<00:36:56.200> will<00:36:56.400> be<00:36:56.839> also 00:36:57.589 --> 00:36:57.599 align:start position:0% a way to organize our Cod will be also 00:36:57.599 --> 00:36:59.069 align:start position:0% a way to organize our Cod will be also another<00:36:57.880> way<00:36:58.040> would<00:36:58.160> be<00:36:58.319> just<00:36:58.440> to<00:36:58.599> shove 00:36:59.069 --> 00:36:59.079 align:start position:0% another way would be just to shove 00:36:59.079 --> 00:37:01.030 align:start position:0% another way would be just to shove everything<00:36:59.440> into<00:36:59.680> the<00:36:59.880> main<00:37:00.400> macro<00:37:00.880> but 00:37:01.030 --> 00:37:01.040 align:start position:0% everything into the main macro but 00:37:01.040 --> 00:37:04.589 align:start position:0% everything into the main macro but that's<00:37:01.640> now<00:37:02.040> we<00:37:02.160> are<00:37:02.440> like<00:37:02.760> a<00:37:03.640> educated<00:37:04.280> people 00:37:04.589 --> 00:37:04.599 align:start position:0% that's now we are like a educated people 00:37:04.599 --> 00:37:07.150 align:start position:0% that's now we are like a educated people so<00:37:04.800> we<00:37:04.880> are<00:37:05.000> not<00:37:05.160> going<00:37:05.359> to<00:37:05.680> to<00:37:05.839> do<00:37:06.079> that<00:37:06.839> uh<00:37:07.000> I'm 00:37:07.150 --> 00:37:07.160 align:start position:0% so we are not going to to do that uh I'm 00:37:07.160 --> 00:37:10.510 align:start position:0% so we are not going to to do that uh I'm going<00:37:07.400> to<00:37:07.880> go<00:37:08.200> through<00:37:08.760> what's<00:37:09.240> in<00:37:09.520> there<00:37:09.839> in<00:37:10.040> a 00:37:10.510 --> 00:37:10.520 align:start position:0% going to go through what's in there in a 00:37:10.520 --> 00:37:14.069 align:start position:0% going to go through what's in there in a second<00:37:11.040> but<00:37:11.280> first<00:37:12.000> I<00:37:12.160> want<00:37:12.480> to<00:37:13.240> talk<00:37:13.720> about 00:37:14.069 --> 00:37:14.079 align:start position:0% second but first I want to talk about 00:37:14.079 --> 00:37:18.510 align:start position:0% second but first I want to talk about the<00:37:14.400> main<00:37:15.000> macro<00:37:16.000> which<00:37:16.119> is<00:37:16.400> just<00:37:17.119> here<00:37:18.119> so<00:37:18.359> as 00:37:18.510 --> 00:37:18.520 align:start position:0% the main macro which is just here so as 00:37:18.520 --> 00:37:21.030 align:start position:0% the main macro which is just here so as I<00:37:18.640> said<00:37:18.960> earlier<00:37:19.760> the<00:37:19.880> main<00:37:20.160> macro<00:37:20.680> is<00:37:20.839> the 00:37:21.030 --> 00:37:21.040 align:start position:0% I said earlier the main macro is the 00:37:21.040 --> 00:37:23.349 align:start position:0% I said earlier the main macro is the first<00:37:21.280> thing<00:37:21.640> that<00:37:21.800> is<00:37:21.960> going<00:37:22.200> to<00:37:22.359> be<00:37:23.160> uh 00:37:23.349 --> 00:37:23.359 align:start position:0% first thing that is going to be uh 00:37:23.359 --> 00:37:24.990 align:start position:0% first thing that is going to be uh called<00:37:23.760> when<00:37:23.960> someone<00:37:24.280> is<00:37:24.440> calling<00:37:24.760> your 00:37:24.990 --> 00:37:25.000 align:start position:0% called when someone is calling your 00:37:25.000 --> 00:37:28.270 align:start position:0% called when someone is calling your contract<00:37:25.800> this<00:37:25.920> is<00:37:26.119> like<00:37:26.359> the<00:37:26.800> the<00:37:26.920> entry<00:37:27.839> so 00:37:28.270 --> 00:37:28.280 align:start position:0% contract this is like the the entry so 00:37:28.280 --> 00:37:31.790 align:start position:0% contract this is like the the entry so in<00:37:28.520> our<00:37:29.119> case<00:37:30.119> uh<00:37:30.520> it's<00:37:30.760> pretty<00:37:31.040> simple<00:37:31.400> so 00:37:31.790 --> 00:37:31.800 align:start position:0% in our case uh it's pretty simple so 00:37:31.800 --> 00:37:35.150 align:start position:0% in our case uh it's pretty simple so let's<00:37:32.040> go<00:37:32.280> let's<00:37:32.480> go<00:37:32.680> through<00:37:33.079> it<00:37:34.079> so<00:37:34.800> okay<00:37:34.960> you 00:37:35.150 --> 00:37:35.160 align:start position:0% let's go let's go through it so okay you 00:37:35.160 --> 00:37:37.270 align:start position:0% let's go let's go through it so okay you guys<00:37:35.400> can<00:37:35.960> so<00:37:36.200> maybe<00:37:36.400> you're<00:37:36.640> writing<00:37:37.000> at<00:37:37.160> the 00:37:37.270 --> 00:37:37.280 align:start position:0% guys can so maybe you're writing at the 00:37:37.280 --> 00:37:40.309 align:start position:0% guys can so maybe you're writing at the same<00:37:37.520> time<00:37:37.760> so<00:37:38.160> I<00:37:38.240> will<00:37:38.520> slow<00:37:38.920> down<00:37:39.440> I'm 00:37:40.309 --> 00:37:40.319 align:start position:0% same time so I will slow down I'm 00:37:40.319 --> 00:37:43.069 align:start position:0% same time so I will slow down I'm sorry<00:37:41.319> so<00:37:41.599> yeah<00:37:41.839> first<00:37:42.240> I<00:37:42.319> think<00:37:42.640> the<00:37:42.960> the 00:37:43.069 --> 00:37:43.079 align:start position:0% sorry so yeah first I think the the 00:37:43.079 --> 00:37:45.870 align:start position:0% sorry so yeah first I think the the easiest<00:37:43.480> thing<00:37:43.640> is<00:37:43.800> just<00:37:43.920> to<00:37:44.079> write<00:37:44.280> the<00:37:44.880> first 00:37:45.870 --> 00:37:45.880 align:start position:0% easiest thing is just to write the first 00:37:45.880 --> 00:37:48.950 align:start position:0% easiest thing is just to write the first uh<00:37:46.400> function<00:37:46.960> definition<00:37:47.680> on<00:37:47.920> top<00:37:48.640> and<00:37:48.800> then 00:37:48.950 --> 00:37:48.960 align:start position:0% uh function definition on top and then 00:37:48.960 --> 00:37:51.910 align:start position:0% uh function definition on top and then you<00:37:49.440> can<00:37:49.640> go<00:37:49.960> directly<00:37:50.400> to<00:37:50.680> this<00:37:51.240> don't<00:37:51.560> write 00:37:51.910 --> 00:37:51.920 align:start position:0% you can go directly to this don't write 00:37:51.920 --> 00:38:02.470 align:start position:0% you can go directly to this don't write this<00:37:52.280> so<00:37:52.960> now<00:37:53.520> we'll<00:37:53.720> do<00:37:53.880> it<00:37:54.760> just<00:37:55.079> after 00:38:02.470 --> 00:38:02.480 align:start position:0% 00:38:02.480 --> 00:38:08.230 align:start position:0% yes 00:38:08.230 --> 00:38:08.240 align:start position:0% 00:38:08.240 --> 00:38:12.390 align:start position:0% yeah<00:38:09.240> uh 00:38:12.390 --> 00:38:12.400 align:start position:0% 00:38:12.400 --> 00:38:15.829 align:start position:0% here 00:38:15.829 --> 00:38:15.839 align:start position:0% 00:38:15.839 --> 00:38:19.790 align:start position:0% oh<00:38:16.839> yes<00:38:17.560> yes<00:38:17.839> so<00:38:18.319> why<00:38:18.599> are<00:38:18.839> we<00:38:19.079> returning 00:38:19.790 --> 00:38:19.800 align:start position:0% oh yes yes so why are we returning 00:38:19.800 --> 00:38:22.190 align:start position:0% oh yes yes so why are we returning nothing<00:38:20.319> here<00:38:20.880> we<00:38:21.000> are<00:38:21.160> not<00:38:21.400> like<00:38:21.640> leaving 00:38:22.190 --> 00:38:22.200 align:start position:0% nothing here we are not like leaving 00:38:22.200 --> 00:38:24.270 align:start position:0% nothing here we are not like leaving anything<00:38:22.560> in<00:38:22.720> the<00:38:22.920> stack<00:38:23.480> it's<00:38:23.720> because<00:38:24.119> we 00:38:24.270 --> 00:38:24.280 align:start position:0% anything in the stack it's because we 00:38:24.280 --> 00:38:28.470 align:start position:0% anything in the stack it's because we are<00:38:24.880> returning<00:38:25.680> here<00:38:26.480> and<00:38:26.839> this<00:38:27.680> return<00:38:27.960> is 00:38:28.470 --> 00:38:28.480 align:start position:0% are returning here and this return is 00:38:28.480 --> 00:38:32.589 align:start position:0% are returning here and this return is actually<00:38:29.480> uh<00:38:29.800> the<00:38:30.359> end<00:38:30.640> of<00:38:30.800> the<00:38:31.200> call<00:38:32.200> so<00:38:32.480> we 00:38:32.589 --> 00:38:32.599 align:start position:0% actually uh the end of the call so we 00:38:32.599 --> 00:38:34.990 align:start position:0% actually uh the end of the call so we are<00:38:32.920> when<00:38:33.119> we<00:38:33.240> are<00:38:33.400> returning<00:38:33.960> something<00:38:34.680> in 00:38:34.990 --> 00:38:35.000 align:start position:0% are when we are returning something in 00:38:35.000 --> 00:38:37.230 align:start position:0% are when we are returning something in half<00:38:35.599> we<00:38:35.720> are<00:38:35.960> actually<00:38:36.359> like 00:38:37.230 --> 00:38:37.240 align:start position:0% half we are actually like 00:38:37.240 --> 00:38:40.470 align:start position:0% half we are actually like returning<00:38:38.280> uh<00:38:39.280> values<00:38:39.680> from<00:38:39.880> the<00:38:40.000> call<00:38:40.319> so 00:38:40.470 --> 00:38:40.480 align:start position:0% returning uh values from the call so 00:38:40.480 --> 00:38:42.069 align:start position:0% returning uh values from the call so it's<00:38:40.680> like<00:38:40.839> the<00:38:40.960> end<00:38:41.160> of<00:38:41.280> the 00:38:42.069 --> 00:38:42.079 align:start position:0% it's like the end of the 00:38:42.079 --> 00:38:46.470 align:start position:0% it's like the end of the call<00:38:43.079> it's<00:38:43.359> it's<00:38:43.720> I<00:38:43.880> know<00:38:44.079> it's<00:38:44.200> a<00:38:44.760> bit<00:38:45.760> the<00:38:46.359> the 00:38:46.470 --> 00:38:46.480 align:start position:0% call it's it's I know it's a bit the the 00:38:46.480 --> 00:38:48.670 align:start position:0% call it's it's I know it's a bit the the names<00:38:46.880> may<00:38:47.079> be<00:38:47.240> a<00:38:47.359> bit<00:38:47.599> confusing<00:38:48.200> right<00:38:48.480> yeah 00:38:48.670 --> 00:38:48.680 align:start position:0% names may be a bit confusing right yeah 00:38:48.680 --> 00:38:50.910 align:start position:0% names may be a bit confusing right yeah because<00:38:48.880> we<00:38:49.040> have<00:38:49.440> returns<00:38:49.920> with<00:38:50.599> which<00:38:50.760> is 00:38:50.910 --> 00:38:50.920 align:start position:0% because we have returns with which is 00:38:50.920 --> 00:38:53.550 align:start position:0% because we have returns with which is not<00:38:51.200> actually<00:38:51.720> returning<00:38:52.480> but<00:38:52.720> just<00:38:53.040> leaving 00:38:53.550 --> 00:38:53.560 align:start position:0% not actually returning but just leaving 00:38:53.560 --> 00:38:56.470 align:start position:0% not actually returning but just leaving stuff<00:38:53.880> in<00:38:54.040> the<00:38:54.200> stack<00:38:54.960> so<00:38:55.240> that's<00:38:55.440> true<00:38:55.720> that's 00:38:56.470 --> 00:38:56.480 align:start position:0% stuff in the stack so that's true that's 00:38:56.480 --> 00:39:01.190 align:start position:0% stuff in the stack so that's true that's it<00:38:56.640> can<00:38:56.760> be<00:38:56.880> a<00:38:56.960> bit<00:38:57.119> confused 00:39:01.190 --> 00:39:01.200 align:start position:0% 00:39:01.200 --> 00:39:04.990 align:start position:0% using<00:39:02.200> so<00:39:02.480> yeah<00:39:02.680> I'll<00:39:02.960> just<00:39:03.640> uh<00:39:04.160> are<00:39:04.319> you<00:39:04.560> guys 00:39:04.990 --> 00:39:05.000 align:start position:0% using so yeah I'll just uh are you guys 00:39:05.000 --> 00:39:08.150 align:start position:0% using so yeah I'll just uh are you guys ready<00:39:05.400> or<00:39:05.520> not<00:39:05.680> to<00:39:05.839> go<00:39:05.960> through<00:39:06.200> the<00:39:06.400> the<00:39:06.560> main 00:39:08.150 --> 00:39:08.160 align:start position:0% ready or not to go through the the main 00:39:08.160 --> 00:39:12.150 align:start position:0% ready or not to go through the the main macro<00:39:09.160> all<00:39:09.319> right<00:39:10.000> okay<00:39:10.240> let's<00:39:10.480> go<00:39:10.839> so<00:39:11.720> now<00:39:12.040> we 00:39:12.150 --> 00:39:12.160 align:start position:0% macro all right okay let's go so now we 00:39:12.160 --> 00:39:14.390 align:start position:0% macro all right okay let's go so now we are<00:39:12.319> going<00:39:12.520> to<00:39:12.680> do<00:39:13.200> what<00:39:13.560> we<00:39:13.680> are<00:39:13.880> calling<00:39:14.240> like 00:39:14.390 --> 00:39:14.400 align:start position:0% are going to do what we are calling like 00:39:14.400 --> 00:39:15.430 align:start position:0% are going to do what we are calling like function 00:39:15.430 --> 00:39:15.440 align:start position:0% function 00:39:15.440 --> 00:39:18.230 align:start position:0% function dispatching<00:39:16.440> uh<00:39:16.599> we<00:39:16.800> have<00:39:17.040> like<00:39:17.200> a<00:39:17.400> very<00:39:17.760> basic 00:39:18.230 --> 00:39:18.240 align:start position:0% dispatching uh we have like a very basic 00:39:18.240 --> 00:39:20.430 align:start position:0% dispatching uh we have like a very basic implementation<00:39:19.240> but<00:39:19.440> it<00:39:19.560> works<00:39:19.920> the<00:39:20.119> exact 00:39:20.430 --> 00:39:20.440 align:start position:0% implementation but it works the exact 00:39:20.440 --> 00:39:25.109 align:start position:0% implementation but it works the exact same<00:39:20.720> way<00:39:21.079> for<00:39:21.440> example<00:39:22.119> in<00:39:23.119> um<00:39:24.119> solidity<00:39:24.839> of 00:39:25.109 --> 00:39:25.119 align:start position:0% same way for example in um solidity of 00:39:25.119 --> 00:39:26.910 align:start position:0% same way for example in um solidity of Viper<00:39:25.760> there<00:39:25.839> are<00:39:26.000> many<00:39:26.240> different<00:39:26.560> ways<00:39:26.760> to 00:39:26.910 --> 00:39:26.920 align:start position:0% Viper there are many different ways to 00:39:26.920 --> 00:39:28.630 align:start position:0% Viper there are many different ways to do<00:39:27.079> this<00:39:27.240> but<00:39:27.480> this<00:39:27.599> is<00:39:27.720> like<00:39:27.880> the<00:39:28.040> most<00:39:28.319> common 00:39:28.630 --> 00:39:28.640 align:start position:0% do this but this is like the most common 00:39:28.640 --> 00:39:30.550 align:start position:0% do this but this is like the most common way<00:39:29.200> so 00:39:30.550 --> 00:39:30.560 align:start position:0% way so 00:39:30.560 --> 00:39:33.470 align:start position:0% way so basically<00:39:31.560> uh<00:39:32.400> what<00:39:32.560> is<00:39:32.680> going<00:39:32.880> to<00:39:33.079> happen<00:39:33.359> is 00:39:33.470 --> 00:39:33.480 align:start position:0% basically uh what is going to happen is 00:39:33.480 --> 00:39:36.109 align:start position:0% basically uh what is going to happen is that<00:39:33.680> someone<00:39:34.000> is<00:39:34.160> going<00:39:34.400> to<00:39:34.680> call<00:39:35.400> our<00:39:35.720> smart 00:39:36.109 --> 00:39:36.119 align:start position:0% that someone is going to call our smart 00:39:36.119 --> 00:39:38.910 align:start position:0% that someone is going to call our smart contract<00:39:37.000> they<00:39:37.200> will<00:39:37.520> send<00:39:38.000> us<00:39:38.240> some<00:39:38.599> call 00:39:38.910 --> 00:39:38.920 align:start position:0% contract they will send us some call 00:39:38.920 --> 00:39:41.710 align:start position:0% contract they will send us some call data<00:39:39.800> and<00:39:39.960> we<00:39:40.160> just<00:39:40.280> want<00:39:40.480> to<00:39:40.599> know<00:39:40.960> okay<00:39:41.359> what 00:39:41.710 --> 00:39:41.720 align:start position:0% data and we just want to know okay what 00:39:41.720 --> 00:39:43.870 align:start position:0% data and we just want to know okay what do<00:39:41.920> they<00:39:42.160> want<00:39:42.319> to<00:39:42.480> do<00:39:42.760> like<00:39:43.040> what<00:39:43.240> is<00:39:43.480> going<00:39:43.680> to 00:39:43.870 --> 00:39:43.880 align:start position:0% do they want to do like what is going to 00:39:43.880 --> 00:39:46.910 align:start position:0% do they want to do like what is going to happen<00:39:44.760> so<00:39:45.319> what<00:39:45.800> we<00:39:45.960> are<00:39:46.160> going<00:39:46.400> to<00:39:46.560> do<00:39:46.720> is 00:39:46.910 --> 00:39:46.920 align:start position:0% happen so what we are going to do is 00:39:46.920 --> 00:39:51.109 align:start position:0% happen so what we are going to do is very<00:39:47.240> simple<00:39:48.240> we<00:39:48.400> say<00:39:48.760> we<00:39:48.960> want<00:39:49.200> to<00:39:50.079> load<00:39:50.560> the<00:39:50.800> C 00:39:51.109 --> 00:39:51.119 align:start position:0% very simple we say we want to load the C 00:39:51.119 --> 00:39:54.390 align:start position:0% very simple we say we want to load the C data<00:39:51.599> so<00:39:52.160> all<00:39:52.359> the<00:39:52.560> values<00:39:53.040> that<00:39:53.240> were<00:39:54.200> uh 00:39:54.390 --> 00:39:54.400 align:start position:0% data so all the values that were uh 00:39:54.400 --> 00:39:57.710 align:start position:0% data so all the values that were uh given<00:39:54.760> to<00:39:55.040> us<00:39:55.720> but<00:39:55.960> we<00:39:56.119> want<00:39:56.359> to<00:39:56.520> load<00:39:56.800> it<00:39:57.599> uh 00:39:57.710 --> 00:39:57.720 align:start position:0% given to us but we want to load it uh 00:39:57.720 --> 00:39:59.630 align:start position:0% given to us but we want to load it uh starting<00:39:58.240> from<00:39:58.560> like<00:39:58.800> the<00:39:59.000> the<00:39:59.119> first<00:39:59.520> the 00:39:59.630 --> 00:39:59.640 align:start position:0% starting from like the the first the 00:39:59.640 --> 00:40:02.790 align:start position:0% starting from like the the first the first<00:39:59.880> bite<00:40:00.200> we<00:40:00.280> want<00:40:00.440> to<00:40:00.560> load<00:40:00.839> it<00:40:01.440> from<00:40:01.720> the 00:40:02.790 --> 00:40:02.800 align:start position:0% first bite we want to load it from the 00:40:02.800 --> 00:40:06.750 align:start position:0% first bite we want to load it from the start<00:40:03.800> and<00:40:04.319> then<00:40:04.880> I<00:40:05.720> maybe<00:40:05.960> you<00:40:06.119> know<00:40:06.400> this<00:40:06.599> or 00:40:06.750 --> 00:40:06.760 align:start position:0% start and then I maybe you know this or 00:40:06.760 --> 00:40:08.790 align:start position:0% start and then I maybe you know this or maybe<00:40:06.960> you<00:40:07.079> don't<00:40:07.240> know<00:40:07.480> but<00:40:07.640> basically<00:40:08.119> like 00:40:08.790 --> 00:40:08.800 align:start position:0% maybe you don't know but basically like 00:40:08.800 --> 00:40:11.390 align:start position:0% maybe you don't know but basically like uh<00:40:09.079> function<00:40:09.680> signatures<00:40:10.680> they<00:40:10.839> only<00:40:11.160> have 00:40:11.390 --> 00:40:11.400 align:start position:0% uh function signatures they only have 00:40:11.400 --> 00:40:14.510 align:start position:0% uh function signatures they only have like<00:40:11.560> four<00:40:12.079> bytes<00:40:12.839> so<00:40:13.400> how<00:40:13.640> does<00:40:13.800> it<00:40:13.960> work<00:40:14.280> when 00:40:14.510 --> 00:40:14.520

00:41:07.440 align:start position:0% uh 20 24 bits so it's like 28 bytes and 00:41:07.440 --> 00:41:09.710 align:start position:0% uh 20 24 bits so it's like 28 bytes and so<00:41:07.760> what<00:41:07.880> is<00:41:08.040> going<00:41:08.200> to<00:41:08.440> happen<00:41:09.119> here<00:41:09.319> we<00:41:09.520> put 00:41:09.710 --> 00:41:09.720 align:start position:0% so what is going to happen here we put 00:41:09.720 --> 00:41:13.430 align:start position:0% so what is going to happen here we put in<00:41:09.880> the<00:41:10.079> stack<00:41:10.960> like<00:41:11.640> the<00:41:11.960> whole<00:41:12.960> like<00:41:13.319> the 00:41:13.430 --> 00:41:13.440 align:start position:0% in the stack like the whole like the 00:41:13.440 --> 00:41:15.990 align:start position:0% in the stack like the whole like the whole<00:41:13.599> call<00:41:13.920> data<00:41:14.160> so<00:41:14.319> we<00:41:14.480> have<00:41:15.040> everything 00:41:15.990 --> 00:41:16.000 align:start position:0% whole call data so we have everything 00:41:16.000 --> 00:41:19.109 align:start position:0% whole call data so we have everything and<00:41:16.440> then<00:41:16.599> we<00:41:16.720> say<00:41:17.040> we<00:41:17.160> want<00:41:17.400> to<00:41:18.000> move<00:41:18.680> to<00:41:18.880> the 00:41:19.109 --> 00:41:19.119 align:start position:0% and then we say we want to move to the 00:41:19.119 --> 00:41:21.670 align:start position:0% and then we say we want to move to the right<00:41:19.760> like<00:41:20.280> all<00:41:20.480> the<00:41:20.640> call<00:41:20.920> data<00:41:21.280> so<00:41:21.400> we<00:41:21.520> are 00:41:21.670 --> 00:41:21.680 align:start position:0% right like all the call data so we are 00:41:21.680 --> 00:41:24.910 align:start position:0% right like all the call data so we are going<00:41:22.079> to<00:41:23.079> move<00:41:23.520> everything<00:41:23.920> to<00:41:24.079> the<00:41:24.280> right 00:41:24.910 --> 00:41:24.920 align:start position:0% going to move everything to the right 00:41:24.920 --> 00:41:29.109 align:start position:0% going to move everything to the right but<00:41:25.119> we<00:41:25.240> are<00:41:25.400> moving<00:41:25.800> to<00:41:26.240> 28<00:41:27.560> bytes<00:41:28.560> so<00:41:28.800> we<00:41:28.920> are 00:41:29.109 --> 00:41:29.119 align:start position:0% but we are moving to 28 bytes so we are 00:41:29.119 --> 00:41:32.870 align:start position:0% but we are moving to 28 bytes so we are going<00:41:29.400> to<00:41:29.800> leave<00:41:30.800> uh<00:41:31.000> a<00:41:31.280> value<00:41:31.960> which<00:41:32.119> is<00:41:32.319> only 00:41:32.870 --> 00:41:32.880 align:start position:0% going to leave uh a value which is only 00:41:32.880 --> 00:41:36.630 align:start position:0% going to leave uh a value which is only what<00:41:33.000> you<00:41:33.119> can<00:41:33.280> do<00:41:33.480> like<00:41:33.680> 32<00:41:34.640> bytes<00:41:35.079> minus<00:41:35.680> 28 00:41:36.630 --> 00:41:36.640 align:start position:0% what you can do like 32 bytes minus 28 00:41:36.640 --> 00:41:38.349 align:start position:0% what you can do like 32 bytes minus 28 and<00:41:36.760> you<00:41:36.920> have<00:41:37.119> four<00:41:37.440> bytes<00:41:37.760> so<00:41:37.880> this<00:41:38.000> is<00:41:38.160> like 00:41:38.349 --> 00:41:38.359 align:start position:0% and you have four bytes so this is like 00:41:38.359 --> 00:41:42.390 align:start position:0% and you have four bytes so this is like the<00:41:38.520> the<00:41:38.640> function<00:41:39.720> selector<00:41:40.720> and<00:41:41.000> so<00:41:41.920> yeah<00:41:42.160> we 00:41:42.390 --> 00:41:42.400 align:start position:0% the the function selector and so yeah we 00:41:42.400 --> 00:41:44.670 align:start position:0% the the function selector and so yeah we have<00:41:42.680> a<00:41:42.800> function<00:41:43.280> selector<00:41:43.720> so<00:41:43.880> we<00:41:44.000> know 00:41:44.670 --> 00:41:44.680 align:start position:0% have a function selector so we know 00:41:44.680 --> 00:41:48.430 align:start position:0% have a function selector so we know which<00:41:44.960> function<00:41:45.480> the<00:41:45.640> sender<00:41:46.560> wants<00:41:47.319> to<00:41:47.800> call 00:41:48.430 --> 00:41:48.440 align:start position:0% which function the sender wants to call 00:41:48.440 --> 00:41:51.150 align:start position:0% which function the sender wants to call but<00:41:49.440> now<00:41:49.599> we<00:41:49.720> need<00:41:49.880> to<00:41:50.040> check<00:41:50.440> okay<00:41:50.599> so<00:41:50.920> do<00:41:51.040> we 00:41:51.150 --> 00:41:51.160 align:start position:0% but now we need to check okay so do we 00:41:51.160 --> 00:41:53.190 align:start position:0% but now we need to check okay so do we have<00:41:51.400> this<00:41:51.599> function<00:41:52.400> maybe<00:41:52.680> we<00:41:52.800> don't<00:41:53.040> have 00:41:53.190 --> 00:41:53.200 align:start position:0% have this function maybe we don't have 00:41:53.200 --> 00:41:55.430 align:start position:0% have this function maybe we don't have it<00:41:53.440> maybe<00:41:53.640> it's<00:41:53.760> a<00:41:53.960> mistake<00:41:54.720> so<00:41:54.960> what<00:41:55.119> is<00:41:55.280> going 00:41:55.430 --> 00:41:55.440 align:start position:0% it maybe it's a mistake so what is going 00:41:55.440 --> 00:41:59.910 align:start position:0% it maybe it's a mistake so what is going to<00:41:55.680> happen<00:41:56.480> here<00:41:56.880> we<00:41:57.079> are<00:41:57.240> are<00:41:57.480> going<00:41:57.839> to<00:41:58.800> uh<00:41:58.960> do 00:41:59.910 --> 00:41:59.920 align:start position:0% to happen here we are are going to uh do 00:41:59.920 --> 00:42:02.589 align:start position:0% to happen here we are are going to uh do exactly<00:42:00.359> like<00:42:00.560> the<00:42:00.680> function<00:42:01.200> dispatching<00:42:02.200> so 00:42:02.589 --> 00:42:02.599 align:start position:0% exactly like the function dispatching so 00:42:02.599 --> 00:42:05.750 align:start position:0% exactly like the function dispatching so we<00:42:02.760> are<00:42:03.119> going<00:42:03.400> to<00:42:03.599> load<00:42:04.079> here<00:42:04.800> our<00:42:05.280> function 00:42:05.750 --> 00:42:05.760 align:start position:0% we are going to load here our function 00:42:05.760 --> 00:42:08.829 align:start position:0% we are going to load here our function signature<00:42:06.599> so<00:42:06.920> this<00:42:07.040> is<00:42:07.319> what<00:42:07.760> we<00:42:07.960> have 00:42:08.829 --> 00:42:08.839 align:start position:0% signature so this is what we have 00:42:08.839 --> 00:42:11.550 align:start position:0% signature so this is what we have compute<00:42:09.520> it's<00:42:09.800> here<00:42:10.119> this<00:42:10.240> is<00:42:10.720> what<00:42:10.880> we<00:42:11.079> Define 00:42:11.550 --> 00:42:11.560 align:start position:0% compute it's here this is what we Define 00:42:11.560 --> 00:42:14.190 align:start position:0% compute it's here this is what we Define and<00:42:11.720> this<00:42:11.839> is<00:42:12.040> what<00:42:12.160> we<00:42:12.280> are<00:42:13.000> expecting<00:42:14.000> and 00:42:14.190 --> 00:42:14.200 align:start position:0% and this is what we are expecting and 00:42:14.200 --> 00:42:17.710 align:start position:0% and this is what we are expecting and then<00:42:14.359> we're<00:42:15.040> going<00:42:15.319> to<00:42:15.480> do<00:42:15.760> like<00:42:16.319> equals<00:42:17.319> so 00:42:17.710 --> 00:42:17.720 align:start position:0% then we're going to do like equals so 00:42:17.720 --> 00:42:20.750 align:start position:0% then we're going to do like equals so equal<00:42:18.280> here<00:42:18.440> is<00:42:18.640> going<00:42:18.880> to<00:42:19.319> check<00:42:19.760> if<00:42:20.440> what<00:42:20.640> we 00:42:20.750 --> 00:42:20.760 align:start position:0% equal here is going to check if what we 00:42:20.760 --> 00:42:24.430 align:start

we<00:42:36.240> say<00:42:36.720> okay<00:42:36.920> so<00:42:37.640> if 00:42:38.630 --> 00:42:38.640 align:start position:0% expecting and then we say okay so if 00:42:38.640 --> 00:42:41.390 align:start position:0% expecting and then we say okay so if it's<00:42:38.839> equal<00:42:39.280> then<00:42:39.480> we'll<00:42:39.760> have<00:42:40.000> a<00:42:40.160> zero<00:42:40.640> here 00:42:41.390 --> 00:42:41.400 align:start position:0% it's equal then we'll have a zero here 00:42:41.400 --> 00:42:43.470 align:start position:0% it's equal then we'll have a zero here uh<00:42:41.559> no<00:42:41.720> sorry<00:42:42.200> um<00:42:42.480> we'll<00:42:42.680> have<00:42:42.800> a<00:42:42.920> one<00:42:43.200> if<00:42:43.319> it's 00:42:43.470 --> 00:42:43.480 align:start position:0% uh no sorry um we'll have a one if it's 00:42:43.480 --> 00:42:46.670 align:start position:0% uh no sorry um we'll have a one if it's not<00:42:43.680> equal<00:42:44.000> we<00:42:44.119> have<00:42:44.599> zero<00:42:45.599> and<00:42:46.040> then<00:42:46.359> we<00:42:46.480> are 00:42:46.670 --> 00:42:46.680 align:start position:0% not equal we have zero and then we are 00:42:46.680 --> 00:42:50.589 align:start position:0% not equal we have zero and then we are just<00:42:46.880> going<00:42:47.119> to<00:42:47.359> call<00:42:47.760> the<00:42:48.319>

if<00:42:54.440> this<00:42:54.559> is<00:42:54.920> zero<00:42:55.880> then<00:42:56.200> we're<00:42:56.480> just 00:42:56.630 --> 00:42:56.640 align:start position:0% simple if this is zero then we're just 00:42:56.640 --> 00:42:59.870 align:start position:0% simple if this is zero then we're just going<00:42:56.839> to<00:42:57.440> continue<00:42:58.280> if<00:42:58.520> this<00:42:58.640>

00:43:03.430 --> 00:43:03.440 align:start position:0% going to jump to here compute the jump 00:43:03.440 --> 00:43:05.990 align:start position:0% going to jump to here compute the jump label<00:43:03.880> I<00:43:03.960> showed<00:43:04.319> you<00:43:05.040> uh<00:43:05.200> I<00:43:05.319> explained<00:43:05.640> to<00:43:05.760> you 00:43:05.990 --> 00:43:06.000 align:start

just let me know if we need to slow<00:43:10.960> down<00:43:11.960> okay<00:43:12.119> you<00:43:12.240> have<00:43:12.480> question<00:43:13.079> uh<00:43:13.319> go 00:43:16.109 --> 00:43:16.119 align:start position:0% 00:43:16.119 --> 00:43:18.950 align:start position:0% ahead<00:43:17.119> what<00:43:17.240> is<00:43:17.319> it<00:43:17.520> doing 00:43:18.950 --> 00:43:18.960 align:start position:0% ahead what is it doing 00:43:18.960 --> 00:43:21.549 align:start position:0% ahead what is it doing exactly<00:43:19.960> on<00:43:20.079> the<00:43:20.280> on<00:43:20.400> the<00:43:20.520> function<00:43:20.880> signature 00:43:21.549 --> 00:43:21.559 align:start position:0% exactly on the on the function signature 00:43:21.559 --> 00:43:23.910 align:start position:0% exactly on the on the function signature how<00:43:21.760> is<00:43:22.000> that<00:43:22.680> could<00:43:22.839> you<00:43:23.079> explain<00:43:23.680> dive 00:43:23.910 --> 00:43:23.920 align:start position:0% how is that could you explain dive 00:43:23.920 --> 00:43:26.630 align:start position:0% how is that could you explain dive deeper<00:43:24.240> into<00:43:24.480> that<00:43:24.920> yeah<00:43:25.040> sure<00:43:25.319> so<00:43:25.640> basically 00:43:26.630 --> 00:43:26.640 align:start position:0% deeper into that yeah sure so basically 00:43:26.640 --> 00:43:29.030 align:start position:0% deeper into that yeah sure so basically uh<00:43:26.880> this<00:43:27.119> this<00:43:27.240> is<00:43:27.880> uh<00:43:28.240> the<00:43:28.400> same<00:43:28.640> thing<00:43:28.839> as 00:43:29.030 --> 00:43:29.040 align:start position:0% uh this this is uh the same thing as 00:43:29.040 --> 00:43:31.790 align:start position:0% uh this this is uh the same thing as solidity<00:43:29.720> when<00:43:29.880> you<00:43:30.040> have<00:43:30.280> like<00:43:30.559> a<00:43:31.200> uh 00:43:31.790 --> 00:43:31.800 align:start position:0% solidity when you have like a uh 00:43:31.800 --> 00:43:34.190 align:start position:0% solidity when you have like a uh encoding<00:43:32.440> something<00:43:33.000> or<00:43:33.400> if<00:43:33.520> you<00:43:33.720> define<00:43:34.000> a 00:43:34.190 --> 00:43:34.200 align:start position:0% encoding something or if you define a 00:43:34.200 --> 00:43:36.069 align:start position:0% encoding something or if you define a function<00:43:34.599> in<00:43:34.800> solidity<00:43:35.400> you<00:43:35.520> can<00:43:35.680> get<00:43:35.920> like 00:43:36.069 --> 00:43:36.079 align:start position:0% function in solidity you can get like 00:43:36.079 --> 00:43:37.670 align:start position:0% function in solidity you can get like the<00:43:36.240> signature<00:43:36.760> you<00:43:36.839> can<00:43:37.000> get<00:43:37.160> like<00:43:37.319> the<00:43:37.400> four 00:43:37.670 --> 00:43:37.680 align:start position:0% the signature you can get like the four 00:43:37.680 --> 00:43:40.230 align:start position:0% the signature you can get like the four bytes<00:43:38.319> and<00:43:38.480> this<00:43:38.559> is<00:43:38.720> the<00:43:38.880> same<00:43:39.119> thing<00:43:39.400> here<00:43:40.119> uh 00:43:40.230 --> 00:43:40.240 align:start position:0% bytes and this is the same thing here uh 00:43:40.240 --> 00:43:43.549 align:start position:0% bytes and this is the same thing here uh we<00:43:40.440> Define<00:43:41.160> this<00:43:41.400> function<00:43:41.960> here<00:43:42.920> like<00:43:43.440> this 00:43:43.549 --> 00:43:43.559 align:start position:0% we Define this function here like this 00:43:43.559 --> 00:43:46.150 align:start position:0% we Define this function here like this is<00:43:43.760> like<00:43:43.960> our<00:43:44.319> function<00:43:45.079> and<00:43:45.440> oh<00:43:45.599> I<00:43:45.720> see<00:43:45.960> so 00:43:46.150 --> 00:43:46.160 align:start position:0% is like our function and oh I see so 00:43:46.160 --> 00:43:47.990 align:start position:0% is like our function and oh I see so it's<00:43:46.319> actually<00:43:46.960> Computing<00:43:47.359> the<00:43:47.520> signature 00:43:47.990 --> 00:43:48.000 align:start position:0% it's actually Computing the signature 00:43:48.000 --> 00:43:49.910 align:start position:0% it's actually Computing the signature function<00:43:48.359> signature<00:43:48.880> from<00:43:49.040> the<00:43:49.240> compute 00:43:49.910 --> 00:43:49.920 align:start position:0% function signature from the compute 00:43:49.920 --> 00:43:52.790 align:start position:0% function signature from the compute exactly<00:43:50.400> it's<00:43:50.680> it's<00:43:50.920> Computing<00:43:51.440> the<00:43:51.640> hash<00:43:52.640> so 00:43:52.790 --> 00:43:52.800 align:start position:0% exactly it's it's Computing the hash so 00:43:52.800 --> 00:43:54.589 align:start position:0% exactly it's it's Computing the hash so the<00:43:52.920> hash<00:43:53.240> of<00:43:53.520> this<00:43:54.040> and<00:43:54.160> then<00:43:54.280> it's<00:43:54.440> just 00:43:54.589 --> 00:43:54.599 align:start position:0% the hash of this and then it's just 00:43:54.599 --> 00:43:57.109 align:start position:0% the hash of this and then it's just going<00:43:54.800> to<00:43:54.960> slice<00:43:55.520> and<00:43:55.680> only<00:43:55.960> get<00:43:56.160> the<00:43:56.280> four 00:43:57.109 --> 00:43:57.119 align:start position:0% going to slice and only get the four 00:43:57.119 --> 00:43:59.150 align:start position:0% going to slice and only get the four first<00:43:57.319> bytes<00:43:57.920> okay<00:43:58.319> could<00:43:58.440> you<00:43:58.720> go<00:43:58.920> back<00:43:59.079> a 00:43:59.150 --> 00:43:59.160 align:start position:0% first bytes okay could you go back a 00:43:59.160 --> 00:44:00.670 align:start position:0% first bytes okay could you go back a little<00:43:59.280> bit<00:43:59.400> on<00:43:59.520> the<00:43:59.640> call<00:43:59.920> data<00:44:00.200> piece<00:44:00.400> so<00:44:00.599> is 00:44:00.670 --> 00:44:00.680 align:start position:0% little bit on the call data piece so is 00:44:00.680 --> 00:44:02.910 align:start position:0% little bit on the call data piece so is it<00:44:00.839> just<00:44:01.000> leaving<00:44:01.319> on<00:44:01.520> the<00:44:01.760> stack<00:44:02.400> the<00:44:02.599> call 00:44:02.910 --> 00:44:02.920 align:start position:0% it just leaving on the stack the call 00:44:02.920 --> 00:44:05.270 align:start position:0% it just leaving on the stack the call the<00:44:03.040> four<00:44:03.319> bytes<00:44:03.680> of<00:44:03.800> the<00:44:04.000> function<00:44:05.000> uh 00:44:05.270 --> 00:44:05.280 align:start position:0% the four bytes of the function uh 00:44:05.280 --> 00:44:08.430 align:start position:0% the four bytes of the function uh signature<00:44:06.200> so<00:44:06.400> basically<00:44:06.960> here<00:44:07.480> we<00:44:07.640> are<00:44:07.960> going 00:44:08.430 --> 00:44:08.440 align:start position:0% signature so basically here we are going 00:44:08.440 --> 00:44:11.190 align:start position:0% signature so basically here we are going to<00:44:09.440> it's<00:44:09.599> a<00:44:09.720> bit<00:44:09.960> weird<00:44:10.359> because<00:44:10.720> like<00:44:11.040> you 00:44:11.190 --> 00:44:11.200 align:start position:0% to it's a bit weird because like you 00:44:11.200 --> 00:44:14.670 align:start position:0% to it's a bit weird because like you know<00:44:11.559> you<00:44:11.720> have<00:44:12.160> to<00:44:13.160> add<00:44:13.599> the<00:44:13.800> value<00:44:14.280> on<00:44:14.520> the 00:44:14.670 --> 00:44:14.680 align:start position:0% know you have to add the value on the 00:44:14.680 --> 00:44:16.510 align:start position:0% know you have to add the value on the stack<00:44:15.040> and<00:44:15.160> then<00:44:15.280> you<00:44:15.400> call<00:44:15.640> the<00:44:15.760> instruction 00:44:16.510 --> 00:44:16.520 align:start position:0% stack and then you call the instruction 00:44:16.520 --> 00:44:18.309 align:start position:0% stack and then you call the instruction so<00:44:16.720> it's<00:44:16.839> a<00:44:16.960> bit<00:44:17.160> hard<00:44:17.359> to<00:44:17.559> explain<00:44:17.960> because<00:44:18.200> I 00:44:18.309 --> 00:44:18.319 align:start position:0% so it's a bit hard to explain because I 00:44:18.319 --> 00:44:20.670 align:start position:0% so it's a bit hard to explain because I need<00:44:18.480> to<00:44:18.720> explain<00:44:19.160> like<00:44:19.480> uh<00:44:19.839> back<00:44:20.040> and<00:44:20.240> forth 00:44:20.670 --> 00:44:20.680 align:start position:0% need to explain like uh back and forth 00:44:20.680 --> 00:44:22.829 align:start position:0% need to explain like uh back and forth what<00:44:20.839> the<00:44:20.960> values<00:44:21.359> or<00:44:21.880> but<00:44:22.079> basically<00:44:22.520> you're 00:44:22.829 --> 00:44:22.839 align:start position:0% what the values or but basically you're 00:44:22.839 --> 00:44:26.270 align:start position:0% what the values or but basically you're like<00:44:23.079> I<00:44:23.200> want<00:44:23.480> to<00:44:24.480> from<00:44:24.720> the<00:44:24.960> start<00:44:25.839> I<00:44:25.960> want<00:44:26.119> to 00:44:26.270 --> 00:44:26.280 align:start position:0% like I want to from the start I want to 00:44:26.280 --> 00:44:27.630 align:start position:0% like I want to from the start I want to load<00:44:26.520> the<00:44:26.680> C<00:44:26.880> dat 00:44:27.630 --> 00:44:27.640 align:start position:0% load the C dat 00:44:27.640 --> 00:44:30.430 align:start position:0% load the C dat so<00:44:27.920> you<00:44:28.040> will<00:44:28.240> be<00:44:28.440> loading<00:44:28.880> the<00:44:29.000> C<00:44:29.319> data<00:44:29.800> from 00:44:30.430 --> 00:44:30.440 align:start position:0% so you will be loading the C data from 00:44:30.440 --> 00:44:33.470 align:start position:0% so you will be loading the C data from the<00:44:30.599> the<00:44:30.800> first<00:44:31.240> bite<00:44:31.640> from<00:44:31.839> the<00:44:32.000> bite<00:44:32.280> zero<00:44:33.280> uh 00:44:33.470 --> 00:44:33.480 align:start position:0% the the first bite from the bite zero uh 00:44:33.480 --> 00:44:36.589 align:start position:0% the the first bite from the bite zero uh but<00:44:33.640> you<00:44:33.880> are<00:44:34.160> going<00:44:34.480> like<00:44:34.599> to<00:44:34.800> load<00:44:35.359> 32<00:44:35.960> bytes 00:44:36.589 --> 00:44:36.599 align:start position:0% but you are going like to load 32 bytes 00:44:36.599 --> 00:44:38.109 align:start position:0% but you are going like to load 32 bytes what<00:44:36.720> is<00:44:36.880> going<00:44:37.040> to<00:44:37.240> happen<00:44:37.520> is<00:44:37.680> that<00:44:37.920> this 00:44:38.109 --> 00:44:38.119 align:start position:0% what is going to happen is that this 00:44:38.119 --> 00:44:40.829 align:start position:0% what is going to happen is that this function<00:44:39.040> is<00:44:39.200> going<00:44:39.400> to<00:44:39.599> take<00:44:39.920> like<00:44:40.200> a<00:44:40.359> slice 00:44:40.829 --> 00:44:40.839 align:start position:0% function is going to take like a slice 00:44:40.839 --> 00:44:44.790 align:start position:0% function is going to take like a slice of<00:44:41.160> 32<00:44:41.680> bytes<00:44:42.280> and<00:44:42.480> put<00:44:42.640> it<00:44:42.760> into<00:44:43.079> the<00:44:43.520> stack<00:44:44.520> so 00:44:44.790 --> 00:44:44.800 align:start position:0% of 32 bytes and put it into the stack so 00:44:44.800 --> 00:44:48.829 align:start position:0% of 32 bytes and put it into the stack so you<00:44:44.920> will<00:44:45.200> have<00:44:46.160> uh<00:44:46.400> so<00:44:46.640> four<00:44:46.960> bytes<00:44:47.520> for<00:44:48.520> uh 00:44:48.829 --> 00:44:48.839 align:start position:0% you will have uh so four bytes for uh 00:44:48.839 --> 00:44:51.309 align:start position:0% you will have uh so four bytes for uh the<00:44:48.960> function<00:44:49.920> uh<00:44:50.160> signature<00:44:50.960> but<00:44:51.119> then<00:44:51.240> you 00:44:51.309 --> 00:44:51.319 align:start position:0% the function uh signature but then you 00:44:51.319 --> 00:44:55.470 align:start position:0% the function uh signature but then you will<00:44:51.520> have<00:44:51.760> 28<00:44:52.559> bytes<00:44:53.280> which<00:44:53.440> will<00:44:53.640> be<00:44:53.880> like<00:44:54.319> uh 00:44:55.470 --> 00:44:55.480 align:start position:0% will have 28 bytes which will be like uh 00:44:55.480 --> 00:44:58.109 align:start position:0% will have 28 bytes which will be like uh non<00:44:56.480> it<00:44:56.559> will<00:44:56.720> be<00:44:57.160> our<00:44:57.440> case<00:44:57.680> it<00:44:57.760> won't<00:44:58.000> be 00:44:58.109 --> 00:44:58.119 align:start position:0% non it will be our case it won't be 00:44:58.119 --> 00:45:00.870 align:start position:0% non it will be our case it won't be nonsense<00:44:58.640> but<00:44:58.839> it<00:44:58.920> will<00:44:59.119> be<00:44:59.520> this<00:45:00.520> uh<00:45:00.720> the 00:45:00.870 --> 00:45:00.880 align:start position:0% nonsense but it will be this uh the 00:45:00.880 --> 00:45:03.589 align:start position:0% nonsense but it will be this uh the first<00:45:01.240> parameter<00:45:01.839> but<00:45:02.240> even<00:45:02.880> it<00:45:03.000> won't<00:45:03.359> even 00:45:03.589 --> 00:45:03.599 align:start position:0% first parameter but even it won't even 00:45:03.599 --> 00:45:06.390 align:start position:0% first parameter but even it won't even be<00:45:03.839> like<00:45:04.000> the<00:45:04.160> whole<00:45:04.800> parameter<00:45:05.599> because<00:45:06.280> this 00:45:06.390 --> 00:45:06.400 align:start position:0% be like the whole parameter because this 00:45:06.400 --> 00:45:10.750 align:start position:0% be like the whole parameter because this is<00:45:06.640> like<00:45:06.839> 32<00:45:07.319> bytes<00:45:08.359> so<00:45:09.359> yeah<00:45:09.960> maybe<00:45:10.559> yeah<00:45:10.680> I 00:45:10.750 --> 00:45:10.760 align:start position:0% is like 32 bytes so yeah maybe yeah I 00:45:10.760 --> 00:45:12.109 align:start position:0% is like 32 bytes so yeah maybe yeah I should<00:45:10.960> have<00:45:11.160> put<00:45:11.400> like<00:45:11.520> a<00:45:11.640> graph<00:45:11.920> or 00:45:12.109 --> 00:45:12.119 align:start position:0% should have put like a graph or 00:45:12.119 --> 00:45:14.390 align:start position:0% should have put like a graph or something<00:45:12.559> it's<00:45:12.760> it's<00:45:12.880> hard<00:45:13.079> to<00:45:13.280> explain<00:45:13.680> this 00:45:14.390 --> 00:45:14.400 align:start position:0% something it's it's hard to explain this 00:45:14.400 --> 00:45:16.190 align:start position:0% something it's it's hard to explain this uh<00:45:14.640> just<00:45:14.880> like<00:45:15.119> this<00:45:15.359> but<00:45:15.760> yeah<00:45:15.880> it<00:45:15.920> would<00:45:16.079> be 00:45:16.190 --> 00:45:16.200 align:start position:0% uh just like this but yeah it would be 00:45:16.200 --> 00:45:18.349 align:start position:0% uh just like this but yeah it would be helpful<00:45:16.559> if<00:45:16.640> you<00:45:16.800> had<00:45:16.960> like<00:45:17.079> the<00:45:17.280> stack<00:45:18.000> on<00:45:18.160> the 00:45:18.349 --> 00:45:18.359 align:start position:0% helpful if you had like the stack on the 00:45:18.359 --> 00:45:20.109 align:start position:0% helpful if you had like the stack on the on<00:45:18.440> the<00:45:18.559> right<00:45:18.760> hand<00:45:18.880> side<00:45:19.280> idea<00:45:19.640> I'll<00:45:19.839> see<00:45:19.960> if 00:45:20.109 --> 00:45:20.119 align:start position:0% on the right hand side idea I'll see if 00:45:20.119 --> 00:45:22.829 align:start position:0% on the right hand side idea I'll see if I<00:45:20.280> I<00:45:20.359> can<00:45:20.520> do<00:45:20.920> something<00:45:21.920> uh<00:45:22.319> yeah<00:45:22.440> I'll<00:45:22.599> see<00:45:22.720> if 00:45:22.829 --> 00:45:22.839 align:start position:0% I I can do something uh yeah I'll see if 00:45:22.839 --> 00:45:25.150 align:start position:0% I I can do something uh yeah I'll see if I<00:45:22.920> can<00:45:23.079> do<00:45:23.240> something<00:45:23.640> actually<00:45:24.000> after<00:45:24.760> but 00:45:25.150 --> 00:45:25.160 align:start position:0% I can do something actually after but 00:45:25.160 --> 00:45:26.990 align:start position:0% I can do something actually after but yeah<00:45:25.319> basically<00:45:26.000> the<00:45:26.119> idea<00:45:26.440> that<00:45:26.559> you<00:45:26.680> all 00:45:26.990 --> 00:45:27.000 align:start position:0% yeah basically the idea that you all 00:45:27.000 --> 00:45:29.710 align:start position:0% yeah basically the idea that you all loading<00:45:27.400> here<00:45:27.800> 32<00:45:28.319> bytes<00:45:28.640> of<00:45:28.800> cold<00:45:29.079> data 00:45:29.710 --> 00:45:29.720 align:start position:0% loading here 32 bytes of cold data 00:45:29.720 --> 00:45:32.349 align:start position:0% loading here 32 bytes of cold data starting<00:45:30.240> at<00:45:30.400> the<00:45:30.599> position<00:45:31.079> zero<00:45:31.960> but<00:45:32.200> in 00:45:32.349 --> 00:45:32.359 align:start position:0% starting at the position zero but in 00:45:32.359 --> 00:45:34.630 align:start position:0% starting at the position zero but in this<00:45:32.559> case<00:45:32.800> we<00:45:32.920> only<00:45:33.160> want<00:45:33.760> the<00:45:33.960> first<00:45:34.319> four 00:45:34.630 --> 00:45:34.640 align:start position:0% this case we only want the first four 00:45:34.640 --> 00:45:38.230 align:start position:0% this case we only want the first four bytes<00:45:35.480> so<00:45:35.839> we<00:45:36.000> say<00:45:36.400> okay<00:45:36.680> let's<00:45:37.040> just<00:45:37.680> move<00:45:38.040> to 00:45:38.230 --> 00:45:38.240 align:start position:0% bytes so we say okay let's just move to 00:45:38.240 --> 00:45:39.190 align:start position:0% bytes so we say okay let's just move to the 00:45:39.190 --> 00:45:39.200 align:start position:0% the 00:45:39.200 --> 00:45:43.030 align:start position:0% the right<00:45:40.200> uh<00:45:40.880> this<00:45:41.200> element<00:45:41.720> in<00:45:41.880> the<00:45:42.079> stack<00:45:42.839> and 00:45:43.030 --> 00:45:43.040 align:start position:0% right uh this element in the stack and 00:45:43.040 --> 00:45:46.670 align:start position:0% right uh this element in the stack and we<00:45:43.160> want<00:45:43.319> to<00:45:43.440> move<00:45:43.680> it<00:45:43.880> to<00:45:44.720> 28<00:45:45.440> bytes<00:45:45.800> so<00:45:46.520> we 00:45:46.670 --> 00:45:46.680 align:start position:0% we want to move it to 28 bytes so we 00:45:46.680 --> 00:45:49.309 align:start position:0% we want to move it to 28 bytes so we move<00:45:46.839> it<00:45:47.079> like<00:45:47.319> this<00:45:48.040> and<00:45:48.240> so<00:45:48.680> we<00:45:48.800> are<00:45:49.000> left 00:45:49.309 --> 00:45:49.319 align:start position:0% move it like this and so we are left 00:45:49.319 --> 00:45:51.150 align:start position:0% move it like this and so we are left with<00:45:49.559> four<00:45:49.839> bytes<00:45:50.400> which<00:45:50.480> is<00:45:50.599> the<00:45:50.720> function 00:45:51.150 --> 00:45:51.160 align:start position:0% with four bytes which is the function 00:45:51.160 --> 00:45:53.390 align:start position:0% with four bytes which is the function signature<00:45:51.920> so<00:45:52.079> on<00:45:52.240> the<00:45:52.400> stack<00:45:52.960> all<00:45:53.160> that's 00:45:53.390 --> 00:45:53.400 align:start position:0% signature so on the stack all that's 00:45:53.400 --> 00:45:55.549 align:start position:0% signature so on the stack all that's left<00:45:53.640> from<00:45:53.800> the<00:45:53.920> call<00:45:54.200> data<00:45:54.440> is<00:45:54.520> the<00:45:55.079> F<00:45:55.359> uh<00:45:55.480> the 00:45:55.549 --> 00:45:55.559 align:start position:0% left from the call data is the F uh the 00:45:55.559 --> 00:45:57.109 align:start position:0% left from the call data is the F uh the first<00:45:55.760> four<00:45:56.000> bytes<00:45:56.319> which<00:45:56.440> is<00:45:56.559> the<00:45:56.640> function 00:45:57.109 --> 00:45:57.119 align:start position:0% first four bytes which is the function 00:45:57.119 --> 00:45:59.829 align:start position:0% first four bytes which is the function signature<00:45:57.800> exactly<00:45:58.480> got<00:45:58.559> it<00:45:59.000> and<00:45:59.240> after<00:45:59.680> we 00:45:59.829 --> 00:45:59.839 align:start position:0% signature exactly got it and after we 00:45:59.839 --> 00:46:01.710 align:start position:0% signature exactly got it and after we just<00:46:00.040> check<00:46:00.480> okay<00:46:00.720> is<00:46:00.839> this<00:46:01.079> like<00:46:01.200> a<00:46:01.400> valid 00:46:01.710 --> 00:46:01.720 align:start position:0% just check okay is this like a valid 00:46:01.720 --> 00:46:03.430 align:start position:0% just check okay is this like a valid function<00:46:02.119> signature<00:46:02.680> because<00:46:02.920> someone<00:46:03.240> can 00:46:03.430 --> 00:46:03.440 align:start position:0% function signature because someone can 00:46:03.440 --> 00:46:05.950 align:start position:0% function signature because someone can just<00:46:03.559> be<00:46:03.800> like<00:46:04.240> spamming<00:46:04.720> our<00:46:05.040> contract<00:46:05.680> so<00:46:05.839> we 00:46:05.950 --> 00:46:05.960 align:start position:0% just be like spamming our contract so we 00:46:05.960 --> 00:46:08.710 align:start position:0% just be like spamming our contract so we need<00:46:06.119> to<00:46:06.559> to<00:46:06.760> do<00:46:07.000> like<00:46:07.119> a<00:46:07.359> proper<00:46:07.720> check<00:46:08.559> uh 00:46:08.710 --> 00:46:08.720 align:start position:0% need to to do like a proper check uh 00:46:08.720 --> 00:46:13.030 align:start position:0% need to to do like a proper check uh which<00:46:08.960> function<00:46:09.640> do<00:46:09.920> they<00:46:10.119> want<00:46:10.359> to<00:46:11.000> call<00:46:12.040> um 00:46:13.030 --> 00:46:13.040 align:start position:0% which function do they want to call um 00:46:13.040 --> 00:46:17.270 align:start position:0% which function do they want to call um so<00:46:13.559> we<00:46:13.720> are<00:46:14.200> going<00:46:15.200>

sorry we are going to load our own<00:46:21.520> function<00:46:22.160> signature<00:46:23.160> what<00:46:23.319> we<00:46:23.520> Define 00:46:23.990 --> 00:46:24.000 align:start position:0% own function signature what we Define 00:46:24.000 --> 00:46:26.470 align:start position:0% own function signature what we Define here<00:46:24.319> into<00:46:24.599> the<00:46:24.760> stack<00:46:25.640> so<00:46:25.920> basically<00:46:26.359> the 00:46:26.470 --> 00:46:26.480 align:start position:0% here into the stack so basically the 00:46:26.480 --> 00:46:28.750 align:start position:0% here into the stack so basically the stack<00:46:26.760> will<00:46:27.119> we<00:46:27.240> will<00:46:27.440> be<00:46:28.000> their<00:46:28.319> function 00:46:28.750 --> 00:46:28.760 align:start position:0% stack will we will be their function 00:46:28.760 --> 00:46:32.470 align:start position:0% stack will we will be their function signature<00:46:29.760> our<00:46:30.119> function<00:46:30.599> signature<00:46:31.440> on 00:46:32.470 --> 00:46:32.480 align:start position:0% signature our function signature on 00:46:32.480 --> 00:46:35.790 align:start position:0% signature our function signature on top<00:46:33.480> and<00:46:33.680> then<00:46:33.880> we'll<00:46:34.119> just<00:46:34.240> do<00:46:34.520> like<00:46:34.920> equal 00:46:35.790 --> 00:46:35.800 align:start position:0% top and then we'll just do like equal 00:46:35.800 --> 00:46:38.950 align:start position:0% top and then we'll just do like equal and<00:46:36.240> both<00:46:36.599> values<00:46:36.960> will<00:46:37.160> be<00:46:37.440> removed<00:46:38.440> and 00:46:38.950 --> 00:46:38.960 align:start position:0% and both values will be removed and 00:46:38.960 --> 00:46:41.309 align:start position:0% and both values will be removed and equal<00:46:39.359> would<00:46:39.559> just<00:46:39.760> leave<00:46:40.280> a<00:46:40.440> zero<00:46:40.880> if<00:46:41.040> they're 00:46:41.309 --> 00:46:41.319 align:start position:0% equal would just leave a zero if they're 00:46:41.319 --> 00:46:43.950 align:start position:0% equal would just leave a zero if they're not<00:46:42.319> uh<00:46:42.520> equal<00:46:43.000> if<00:46:43.160> they<00:46:43.240> are<00:46:43.400> not<00:46:43.599> like<00:46:43.800> the 00:46:43.950 --> 00:46:43.960 align:start position:0% not uh equal if they are not like the 00:46:43.960 --> 00:46:47.309 align:start position:0% not uh equal if they are not like the same<00:46:44.440> and<00:46:44.559> you<00:46:44.720> will<00:46:44.960> put<00:46:45.520> one<00:46:45.880> if<00:46:46.240> like<00:46:46.480> both 00:46:47.309 --> 00:46:47.319 align:start position:0% same and you will put one if like both 00:46:47.319 --> 00:46:50.430 align:start position:0% same and you will put one if like both signatures<00:46:48.119> are<00:46:48.520> the<00:46:48.839> same<00:46:49.839> uh<00:46:50.000> I<00:46:50.119> just<00:46:50.280> want 00:46:50.430 --> 00:46:50.440 align:start position:0% signatures are the same uh I just want 00:46:50.440 --> 00:46:54.510 align:start position:0% signatures are the same uh I just want to<00:46:51.240> yeah<00:46:51.559> there<00:46:51.680> is<00:46:52.119> like<00:46:53.119> d<00:46:53.680> here<00:46:53.960> duplicate 00:46:54.510 --> 00:46:54.520 align:start position:0% to yeah there is like d here duplicate 00:46:54.520 --> 00:46:57.190 align:start position:0% to yeah there is like d here duplicate one<00:46:55.319> uh<00:46:55.440> this<00:46:55.559> is<00:46:55.720> not<00:46:55.920> needed<00:46:56.319> here<00:46:56.480> so<00:46:57.040> not 00:46:57.190 --> 00:46:57.200 align:start position:0% one uh this is not needed here so not 00:46:57.200 --> 00:46:59.309 align:start position:0% one uh this is not needed here so not going<00:46:57.400> to<00:46:57.559> talk<00:46:57.800> about<00:46:58.040> it<00:46:58.680> we'll<00:46:58.839> see<00:46:59.079> that 00:46:59.309 --> 00:46:59.319 align:start position:0% going to talk about it we'll see that 00:46:59.319 --> 00:47:01.430 align:start position:0% going to talk about it we'll see that after<00:46:59.880> but<00:47:00.079> this<00:47:00.160> is<00:47:00.319> not<00:47:00.520> needed<00:47:00.960> here<00:47:01.200> so 00:47:01.430 --> 00:47:01.440 align:start position:0% after but this is not needed here so 00:47:01.440 --> 00:47:06.230 align:start position:0% after but this is not needed here so don't<00:47:01.720> worry<00:47:02.040> about<00:47:02.280> it<00:47:03.200> um<00:47:04.200> and<00:47:04.680> yeah<00:47:05.079> so<00:47:05.640> we 00:47:06.230 --> 00:47:06.240 align:start position:0% don't worry about it um and yeah so we 00:47:06.240 --> 00:47:09.870 align:start position:0% don't worry about it um and yeah so we are<00:47:07.240> are<00:47:07.480> checking<00:47:08.040> here<00:47:08.880> and<00:47:09.240> yeah<00:47:09.440> like<00:47:09.720> the 00:47:09.870 --> 00:47:09.880 align:start position:0% are are checking here and yeah like the 00:47:09.880 --> 00:47:12.589 align:start position:0% are are checking here and yeah like the the<00:47:10.079> final<00:47:10.559> thing<00:47:10.720> to<00:47:10.920> do<00:47:11.119> is<00:47:11.319> just<00:47:11.440> to<00:47:11.640> jump 00:47:12.589 --> 00:47:12.599 align:start position:0% the final thing to do is just to jump 00:47:12.599 --> 00:47:17.069 align:start position:0% the final thing to do is just to jump accordingly<00:47:13.599> if<00:47:14.359> the<00:47:15.160> um<00:47:15.480> function<00:47:16.079> signature 00:47:17.069 --> 00:47:17.079 align:start position:0% accordingly if the um function signature 00:47:17.079 --> 00:47:19.109 align:start position:0% accordingly if the um function signature is<00:47:17.280> valid<00:47:17.920> if<00:47:18.079> we<00:47:18.240> have<00:47:18.440> something<00:47:18.839> that<00:47:19.000> we 00:47:19.109 --> 00:47:19.119 align:start position:0% is valid if we have something that we 00:47:19.119 --> 00:47:19.870 align:start position:0% is valid if we have something that we are 00:47:19.870 --> 00:47:19.880 align:start position:0% are 00:47:19.880 --> 00:47:23.549 align:start position:0% are expecting<00:47:20.880> then<00:47:21.400> we<00:47:21.599> jump<00:47:22.240> here<00:47:22.440> to<00:47:22.680> compute 00:47:23.549 --> 00:47:23.559 align:start position:0% expecting then we jump here to compute 00:47:23.559 --> 00:47:26.069 align:start position:0% expecting then we jump here to compute and<00:47:23.880> in<00:47:24.119> our<00:47:24.520> case<00:47:25.079> we<00:47:25.240> decided<00:47:25.640> to<00:47:25.800> make 00:47:26.069 --> 00:47:26.079 align:start position:0% and in our case we decided to make 00:47:26.079 --> 00:47:29.230 align:start position:0% and in our case we decided to make things<00:47:27.160> proper<00:47:27.520> way<00:47:27.880> so<00:47:28.280> we<00:47:28.480> Define<00:47:29.000> like<00:47:29.119> a 00:47:29.230 --> 00:47:29.240 align:start position:0% things proper way so we Define like a 00:47:29.240 --> 00:47:32.270 align:start position:0% things proper way so we Define like a macro<00:47:30.040> for<00:47:30.520> compute<00:47:31.480> the<00:47:31.599> other<00:47:31.880> solution 00:47:32.270 --> 00:47:32.280 align:start position:0% macro for compute the other solution 00:47:32.280 --> 00:47:34.510 align:start position:0% macro for compute the other solution would<00:47:32.440> be<00:47:32.599> just<00:47:32.720> to<00:47:32.839> shove<00:47:33.280> all<00:47:33.440> the<00:47:33.599> code<00:47:33.920> here 00:47:34.510 --> 00:47:34.520 align:start position:0% would be just to shove all the code here 00:47:34.520 --> 00:47:37.950 align:start position:0% would be just to shove all the code here but<00:47:34.800> uh<00:47:35.280> it's<00:47:35.960> just<00:47:36.200> cleaner<00:47:36.720> to<00:47:36.960> to<00:47:37.079> do<00:47:37.240> it 00:47:37.950 --> 00:47:37.960 align:start position:0% but uh it's just cleaner to to do it 00:47:37.960 --> 00:47:41.230 align:start position:0% but uh it's just cleaner to to do it here<00:47:38.960> and<00:47:39.400> yeah<00:47:39.640> if<00:47:40.040> they<00:47:40.200> don't<00:47:40.520> have<00:47:41.000> like 00:47:41.230 --> 00:47:41.240 align:start position:0% here and yeah if they don't have like 00:47:41.240 --> 00:47:43.390 align:start position:0% here and yeah if they don't have like the<00:47:41.440> a<00:47:41.599> valid<00:47:41.880> function<00:47:42.280> signature<00:47:43.200> we're 00:47:43.390 --> 00:47:43.400 align:start position:0% the a valid function signature we're 00:47:43.400 --> 00:47:45.870 align:start position:0% the a valid function signature we're just<00:47:43.559> going<00:47:43.720> to<00:47:44.000> revert<00:47:45.000> uh<00:47:45.119> we<00:47:45.280> don't<00:47:45.520> care 00:47:45.870 --> 00:47:45.880 align:start position:0% just going to revert uh we don't care 00:47:45.880 --> 00:47:49.190 align:start position:0% just going to revert uh we don't care they<00:47:46.160> they<00:47:46.319> don't<00:47:47.319> uh<00:47:47.520> they're<00:47:47.760> not<00:47:48.040> like<00:47:48.480> uh 00:47:49.190 --> 00:47:49.200 align:start position:0% they they don't uh they're not like uh 00:47:49.200 --> 00:47:51.109 align:start position:0% they they don't uh they're not like uh asking<00:47:49.520> for<00:47:49.760> the<00:47:49.920> right<00:47:50.160> function<00:47:50.559> so<00:47:50.880> we<00:47:50.960> are 00:47:51.109 --> 00:47:51.119 align:start position:0% asking for the right function so we are 00:47:51.119 --> 00:47:54.470 align:start position:0% asking for the right function so we are not<00:47:51.400> like<00:47:51.800> uh<00:47:52.200> reverting<00:47:53.079> uh<00:47:53.480>

uh reverting uh with any extra data<00:47:54.760> we're<00:47:55.000> just<00:47:55.240> returning<00:47:55.880> zero<00:47:56.599> value 00:47:56.829 --> 00:47:56.839 align:start position:0% data

the<00:48:20.880> main<00:48:21.119> functions<00:48:21.720> you<00:48:21.880> have<00:48:22.079> a<00:48:22.280> reth 00:48:22.670 --> 00:48:22.680 align:start position:0% and the main functions you

align:start position:0% thing in solidity you can revert here 00:48:57.480 --> 00:49:01.549 align:start position:0% thing in solidity you can revert here but<00:48:57.760> then<00:48:58.599> uh<00:48:58.880> the<00:48:59.040> call<00:48:59.319> can<00:49:00.359> continue<00:49:01.359> it's 00:49:01.549 --> 00:49:01.559 align:start position:0% but then uh the call can continue it's 00:49:01.559 --> 00:49:03.630 align:start position:0% but then uh the call can continue it's the<00:49:01.640> same<00:49:01.960> continue<00:49:02.520> infinitely<00:49:03.079> until<00:49:03.400>

is the 00:49:09.960 --> 00:49:11.950 align:start position:0% it uh not the right way uh this is the end<00:49:10.240> of<00:49:10.440> the<00:49:10.640> the<00:49:10.760> transaction<00:49:11.359>

00:49:18.040 --> 00:49:20.870 align:start position:0% after uh other uh upod to execute but if you<00:49:18.280> just<00:49:19.000> if<00:49:19.119> you<00:49:19.280> reach<00:49:19.599> like<00:49:19.799> the<00:49:19.960> end<00:49:20.760> in 00:49:20.870 --> 00:49:20.880 align:start position:0% you just if you reach like the end in 00:49:20.880 --> 00:49:23.750 align:start position:0% you just if you reach like the end in this<00:49:21.040> case<00:49:21.240> we<00:49:21.359> are<00:49:21.520> reverting<00:49:22.559> but<00:49:23.559> it 00:49:23.750 --> 00:49:23.760 align:start position:0% this case we are reverting but it 00:49:23.760 --> 00:49:26.950 align:start position:0% this case we are reverting but it depends<00:49:24.079> on<00:49:24.400> like<00:49:25.400> uh<00:49:25.720> well<00:49:26.400> how<00:49:26.760> you're 00:49:26.950 --> 00:49:26.960 align:start position:0% depends on like uh well how you're 00:49:26.960 --> 00:49:29.470 align:start position:0% depends on like uh well how you're writing<00:49:27.319> your<00:49:27.520> contract<00:49:27.960> and<00:49:28.760> who<00:49:28.960> is<00:49:29.119> calling 00:49:29.470 --> 00:49:29.480 align:start position:0% writing your contract and who is calling 00:49:29.480 --> 00:49:32.270 align:start position:0% writing your contract and who is calling your<00:49:29.720> contract<00:49:30.559> because<00:49:30.920> like<00:49:31.119> if<00:49:31.280> you<00:49:32.160> I 00:49:32.270 --> 00:49:32.280 align:start position:0% your contract because like if you I 00:49:32.280 --> 00:49:33.670 align:start position:0% your contract because like if you I don't<00:49:32.400> know<00:49:32.640> like 00:49:33.670 --> 00:49:33.680 align:start position:0% don't know like 00:49:33.680 --> 00:49:36.270 align:start position:0% don't know like uh<00:49:34.680> I<00:49:34.760> mean<00:49:35.079> it<00:49:35.359> it<00:49:35.480> depends<00:49:35.880> I<00:49:35.960> don't<00:49:36.079> know 00:49:36.270 --> 00:49:36.280 align:start position:0% uh I mean it it depends I don't know 00:49:36.280 --> 00:49:39.349 align:start position:0% uh I mean it it depends I don't know exactly<00:49:36.640> how<00:49:36.760> to<00:49:36.920> ENT<00:49:37.400> this<00:49:38.000> but<00:49:38.520> uh<00:49:38.960> yeah<00:49:39.160> like 00:49:39.349 --> 00:49:39.359 align:start position:0% exactly how to ENT this but uh yeah like 00:49:39.359 --> 00:49:42.230 align:start position:0% exactly how to ENT this but uh yeah like basically<00:49:40.319> it<00:49:40.440> will<00:49:40.680> consume<00:49:41.119> gas<00:49:41.440> but<00:49:41.680> if<00:49:41.839> you 00:49:42.230 --> 00:49:42.240 align:start position:0% basically it will consume gas but if you 00:49:42.240 --> 00:49:44.470 align:start position:0% basically it will consume gas but if you reach<00:49:42.680> the<00:49:42.880> end<00:49:43.119> of<00:49:43.240> the<00:49:43.400> goal<00:49:44.000> then<00:49:44.119> it<00:49:44.240> will 00:49:44.470 --> 00:49:44.480 align:start position:0% reach the end of the goal then it will 00:49:44.480 --> 00:49:46.870 align:start position:0% reach the end of the goal then it will just<00:49:44.640> stop<00:49:45.000> consuming<00:49:45.520> gas<00:49:46.160> you<00:49:46.319> know<00:49:46.640> because 00:49:46.870 --> 00:49:46.880 align:start position:0% just stop consuming gas you know because 00:49:46.880 --> 00:49:49.109 align:start position:0% just stop consuming gas you know because it's<00:49:47.040> only<00:49:47.280> consuming<00:49:47.760> gas<00:49:48.040> when<00:49:48.200> it's<00:49:48.520> like 00:49:49.109 --> 00:49:49.119 align:start position:0% it's only consuming gas when it's like 00:49:49.119 --> 00:49:51.589 align:start position:0% it's only consuming gas when it's like executing<00:49:49.960> operations<00:49:50.960> but<00:49:51.119> if<00:49:51.280> there<00:49:51.400> is 00:49:51.589 --> 00:49:51.599 align:start position:0% executing operations but if there is 00:49:51.599 --> 00:49:53.510 align:start position:0% executing operations but if there is nothing<00:49:51.920> left<00:49:52.119> to<00:49:52.319> execute<00:49:52.920> then<00:49:53.319> the 00:49:53.510 --> 00:49:53.520 align:start position:0% nothing left to execute then the 00:49:53.520 --> 00:49:56.150 align:start position:0% nothing left to execute then the transaction<00:49:54.000> will<00:49:54.200> just<00:49:54.359> stop<00:49:54.960> okay<00:49:55.160> so<00:49:55.520> if<00:49:55.760> I 00:49:56.150 --> 00:49:56.160 align:start position:0% transaction will just stop okay so if I 00:49:56.160 --> 00:49:59.549 align:start position:0% transaction will just stop okay so if I remove<00:49:56.480> the<00:49:56.960> return<00:49:57.400> or<00:49:57.839> or<00:49:58.040> the<00:49:58.240> revert<00:49:59.240> H<00:49:59.359> it 00:49:59.549 --> 00:49:59.559 align:start position:0% remove the return or or the revert H it 00:49:59.559 --> 00:50:02.589 align:start position:0% remove the return or or the revert H it just<00:49:59.839> stops<00:50:00.480> completely<00:50:01.040> uh<00:50:01.440> if<00:50:01.559> you<00:50:01.760> do<00:50:02.000> that 00:50:02.589 --> 00:50:02.599 align:start position:0% just stops completely uh if you do that 00:50:02.599 --> 00:50:04.950 align:start position:0% just stops completely uh if you do that uh<00:50:03.119> if<00:50:03.240> you<00:50:03.400> remove<00:50:03.760> the<00:50:04.160> return<00:50:04.480> here<00:50:04.720> I'm<00:50:04.839> not 00:50:04.950 --> 00:50:04.960 align:start position:0% uh if you remove the return here I'm not 00:50:04.960 --> 00:50:08.109 align:start position:0% uh if you remove the return here I'm not sure<00:50:05.160> what<00:50:05.319> you<00:50:05.480> will<00:50:05.680> do<00:50:06.319> actually 00:50:08.109 --> 00:50:08.119 align:start position:0% sure what you will do actually 00:50:08.119 --> 00:50:10.990 align:start position:0% sure what you will do actually um<00:50:09.119> that's<00:50:09.280> a<00:50:09.640> good<00:50:09.960> question<00:50:10.440> I<00:50:10.520> think<00:50:10.760> we'll 00:50:10.990 --> 00:50:11.000 align:start position:0% um that's a good question I think we'll 00:50:11.000 --> 00:50:15.670 align:start position:0% um that's a good question I think we'll stop<00:50:11.520> because<00:50:12.440> uh<00:50:12.839> this<00:50:13.839> is<00:50:14.520> here<00:50:14.920> actually<00:50:15.400> in 00:50:15.670 --> 00:50:15.680 align:start position:0% stop because uh this is here actually in 00:50:15.680 --> 00:50:18.069 align:start position:0% stop because uh this is here actually in like<00:50:15.960> the<00:50:16.599> the<00:50:16.760> code<00:50:17.040> this<00:50:17.160> will<00:50:17.319> be<00:50:17.559> compiled 00:50:18.069 --> 00:50:18.079 align:start position:0% like the the code this will be compiled 00:50:18.079 --> 00:50:20.710 align:start position:0% like the the code this will be compiled at<00:50:18.240> the<00:50:18.400> end<00:50:19.119> of<00:50:19.359> our<00:50:19.720> contract<00:50:20.200> and<00:50:20.359> then<00:50:20.520> if 00:50:20.710 --> 00:50:20.720 align:start position:0% at the end of our contract and then if 00:50:20.720 --> 00:50:23.270 align:start position:0% at the end of our contract and then if you<00:50:20.839> do<00:50:21.079> this<00:50:21.359> then<00:50:21.599> after<00:50:22.280> the<00:50:22.440> contract<00:50:23.000> has 00:50:23.270 --> 00:50:23.280 align:start position:0% you do this then after the contract has 00:50:23.280 --> 00:50:26.230 align:start position:0% you do this then after the contract has ended<00:50:24.040> so<00:50:24.240> I<00:50:24.319> think<00:50:24.480> it<00:50:24.559> will<00:50:24.839> just<00:50:25.240> stop<00:50:26.040> but 00:50:26.230 --> 00:50:26.240 align:start position:0% ended so I think it will just stop but 00:50:26.240 --> 00:50:28.549 align:start position:0% ended so I think it will just stop but otherwise<00:50:26.920> you<00:50:27.079> can<00:50:27.799> if<00:50:27.920> you<00:50:28.079> forgot 00:50:28.549 --> 00:50:28.559 align:start position:0% otherwise you can if you forgot 00:50:28.559 --> 00:50:30.950 align:start position:0% otherwise you can if you forgot something<00:50:28.880> you<00:50:29.000> can<00:50:29.160> make<00:50:29.319> a<00:50:29.480> loop<00:50:30.400> uh<00:50:30.599> if<00:50:30.720> you 00:50:30.950 --> 00:50:30.960 align:start position:0% something you can make a loop uh if you 00:50:30.960 --> 00:50:33.309 align:start position:0% something you can make a loop uh if you put<00:50:31.280> like<00:50:31.799> here<00:50:32.119> something<00:50:32.880> then<00:50:33.000> it<00:50:33.119> will 00:50:33.309 --> 00:50:33.319 align:start position:0% put like here something then it will 00:50:33.319 --> 00:50:35.670 align:start position:0% put like here something then it will jump<00:50:33.640> here<00:50:33.880> and<00:50:34.079> go<00:50:34.319> here<00:50:34.480> and<00:50:34.680> jump<00:50:35.040> here<00:50:35.520> like 00:50:35.670 --> 00:50:35.680 align:start position:0% jump here and go here and jump here like 00:50:35.680 --> 00:50:37.190 align:start position:0% jump here and go here and jump here like it<00:50:35.799> will<00:50:35.960> be<00:50:36.079> a<00:50:36.160> loop<00:50:36.400> he<00:50:36.520> will<00:50:36.680> consume<00:50:37.040> all 00:50:37.190 --> 00:50:37.200 align:start position:0% it will be a loop he will consume all 00:50:37.200 --> 00:50:39.829 align:start position:0% it will be a loop he will consume all the<00:50:37.359> gas<00:50:37.559> and<00:50:37.799> just<00:50:38.400> River<00:50:38.839> twist<00:50:39.160> out<00:50:39.319> of<00:50:39.520> gas 00:50:39.829 --> 00:50:39.839 align:start position:0% the gas and just River twist out of gas 00:50:39.839 --> 00:50:43.190 align:start position:0% the gas and just River twist out of gas actually<00:50:40.680> okay<00:50:40.960> perfect<00:50:41.359> thank<00:50:41.960> you<00:50:42.960> uh 00:50:43.190 --> 00:50:43.200 align:start position:0% actually okay perfect thank you uh 00:50:43.200 --> 00:50:46.990 align:start position:0% actually okay perfect thank you uh question<00:50:43.640> about<00:50:43.960> the<00:50:44.480> 0x00<00:50:45.480> cold<00:50:45.760> data<00:50:46.079> load 00:50:46.990 --> 00:50:47.000 align:start position:0% question about the 0x00 cold data load 00:50:47.000 --> 00:50:51.150 align:start position:0% question about the 0x00 cold data load uh<00:50:47.839> yes<00:50:48.839> so<00:50:49.359> that<00:50:49.480> sounds<00:50:49.760> a<00:50:49.920> bit<00:50:50.280> heavy<00:50:50.760> is 00:50:51.150 --> 00:50:51.160 align:start position:0% uh yes so that sounds a bit heavy is 00:50:51.160 --> 00:50:52.950 align:start position:0% uh yes so that sounds a bit heavy is that<00:50:51.400> the<00:50:51.559> most<00:50:51.839> efficient<00:50:52.280> way<00:50:52.400> of<00:50:52.559> getting 00:50:52.950 --> 00:50:52.960 align:start position:0% that the most efficient way of getting 00:50:52.960 --> 00:50:57.670 align:start position:0% that the most efficient way of getting the<00:50:53.240> extracting<00:50:53.839> the<00:50:54.119> the<00:50:54.240> selector<00:50:55.079> mhm<00:50:56.079> okay 00:50:57.670 --> 00:50:57.680 align:start position:0% the extracting the the selector mhm okay 00:50:57.680 --> 00:50:59.470 align:start position:0% the extracting the the selector mhm okay yeah<00:50:57.920> because<00:50:58.319> you<00:50:58.520> can<00:50:58.680> when<00:50:58.799> you're<00:50:59.119> using 00:50:59.470 --> 00:50:59.480 align:start position:0% yeah because you can when you're using 00:50:59.480 --> 00:51:01.510 align:start position:0% yeah because you can when you're using like<00:50:59.640> cold<00:50:59.920> data<00:51:00.200> load<00:51:00.760> you<00:51:00.880> can<00:51:01.040> only<00:51:01.240> load 00:51:01.510 --> 00:51:01.520 align:start position:0% like cold data load you can only load 00:51:01.520 --> 00:51:04.789 align:start position:0% like cold data load you can only load like<00:51:01.680> 32<00:51:02.839> bytes<00:51:03.839> you're<00:51:04.079> loading<00:51:04.480> like<00:51:04.680> a 00:51:04.789 --> 00:51:04.799 align:start position:0% like 32 bytes you're loading like a 00:51:04.799 --> 00:51:07.109 align:start position:0% like 32 bytes you're loading like a whole<00:51:05.559> piece<00:51:05.960> of<00:51:06.200> information<00:51:06.680> into<00:51:06.920> the 00:51:07.109 --> 00:51:07.119 align:start position:0% whole piece of information into the 00:51:07.119 --> 00:51:10.829 align:start position:0% whole piece of information into the stack<00:51:07.799> then<00:51:07.920> you<00:51:08.040> have<00:51:08.160> to<00:51:08.319> move<00:51:08.559> forward<00:51:09.359> to 00:51:10.829 --> 00:51:10.839 align:start position:0% stack then you have to move forward to 00:51:10.839 --> 00:51:15.470 align:start position:0% stack then you have to move forward to um<00:51:11.839> to<00:51:12.079> get<00:51:12.480> uh<00:51:12.920> the<00:51:13.599> the<00:51:14.599> the<00:51:14.799> actual<00:51:15.079> function 00:51:15.470 --> 00:51:15.480 align:start position:0% um to get uh the the the actual function 00:51:15.480 --> 00:51:18.150 align:start position:0% um to get uh the the the actual function selector<00:51:16.280> there<00:51:16.400> is<00:51:16.680> another<00:51:17.119> way<00:51:17.440> actually 00:51:18.150 --> 00:51:18.160 align:start position:0% selector there is another way actually 00:51:18.160 --> 00:51:20.710 align:start position:0% selector there is another way actually and<00:51:18.319> I<00:51:18.400> think<00:51:18.599> you<00:51:18.720> can<00:51:18.920> load<00:51:19.359> like<00:51:19.559> a<00:51:19.799> single 00:51:20.710 --> 00:51:20.720 align:start position:0% and I think you can load like a single 00:51:20.720 --> 00:51:24.069 align:start position:0% and I think you can load like a single bite<00:51:21.720> uh<00:51:21.880> from<00:51:22.119> the<00:51:22.280> cold<00:51:22.640> data<00:51:23.319> but<00:51:23.799> that<00:51:23.960> that 00:51:24.069 --> 00:51:24.079 align:start position:0% bite uh from the cold data but that that 00:51:24.079 --> 00:51:26.109 align:start position:0% bite uh from the cold data but that that is<00:51:24.240> not<00:51:24.520> standard<00:51:25.000> so<00:51:25.160> you<00:51:25.240> can<00:51:25.480> do<00:51:25.680> it<00:51:25.920> but 00:51:26.109 --> 00:51:26.119 align:start position:0% is not standard so you can do it but 00:51:26.119 --> 00:51:28.069 align:start position:0% is not standard so you can do it but it's<00:51:26.280> not<00:51:26.599> like<00:51:26.720> the<00:51:26.880> standard<00:51:27.280> way<00:51:27.680> so<00:51:27.920> you 00:51:28.069 --> 00:51:28.079 align:start position:0% it's not like the standard way so you 00:51:28.079 --> 00:51:29.630 align:start position:0% it's not like the standard way so you you<00:51:28.200> could<00:51:28.359> be<00:51:28.559> like<00:51:28.720> loading<00:51:29.160> I<00:51:29.280> don't<00:51:29.480> like 00:51:29.630 --> 00:51:29.640 align:start position:0% you could be like loading I don't like 00:51:29.640 --> 00:51:32.829 align:start position:0% you could be like loading I don't like the<00:51:29.839> first<00:51:30.839> uh<00:51:31.640> uh<00:51:31.799> you<00:51:31.920> say<00:51:32.240> okay<00:51:32.480> this<00:51:32.599> is 00:51:32.829 --> 00:51:32.839 align:start position:0% the first uh uh you say okay this is 00:51:32.839 --> 00:51:36.109 align:start position:0% the first uh uh you say okay this is like<00:51:33.280> one<00:51:33.760> and<00:51:34.040> if<00:51:34.319> this<00:51:34.440> is<00:51:34.680> one<00:51:35.240> we<00:51:35.440> compute 00:51:36.109 --> 00:51:36.119 align:start position:0% like one and if this is one we compute 00:51:36.119 --> 00:51:38.950 align:start position:0% like one and if this is one we compute or<00:51:36.400> we<00:51:36.720> we<00:51:36.920> go<00:51:37.079> to<00:51:37.520> something<00:51:37.920> that<00:51:38.079> will<00:51:38.359> add 00:51:38.950 --> 00:51:38.960 align:start position:0% or we we go to something that will add 00:51:38.960 --> 00:51:40.950 align:start position:0% or we we go to something that will add if<00:51:39.160> this<00:51:39.280> is<00:51:39.480> two<00:51:39.960> then<00:51:40.119> we<00:51:40.240> can<00:51:40.480> go<00:51:40.680> to 00:51:40.950 --> 00:51:40.960 align:start position:0% if this is two then we can go to 00:51:40.960 --> 00:51:43.309 align:start position:0% if this is two then we can go to something<00:51:41.319> that<00:51:41.480> will<00:51:41.640> do<00:51:42.160> minus<00:51:43.160> uh 00:51:43.309 --> 00:51:43.319 align:start position:0% something that will do minus uh 00:51:43.319 --> 00:51:45.789 align:start position:0% something that will do minus uh substract<00:51:43.920> things<00:51:44.200> like<00:51:44.400> that<00:51:44.640> but<00:51:45.640> the 00:51:45.789 --> 00:51:45.799 align:start position:0% substract things like that but the 00:51:45.799 --> 00:51:49.109 align:start position:0% substract things like that but the standard<00:51:46.240> way<00:51:46.400> is<00:51:46.559> like<00:51:46.680> for<00:51:47.000> for 00:51:49.109 --> 00:51:49.119 align:start position:0% standard way is like for for 00:51:49.119 --> 00:51:54.309 align:start position:0% standard way is like for for byes<00:51:50.119> um<00:51:51.040> yes<00:51:51.400> so<00:51:51.880> we<00:51:52.200> can<00:51:53.200> continue<00:51:53.880> so 00:51:54.309 --> 00:51:54.319 align:start position:0% byes um yes so we can continue so 00:51:54.319 --> 00:51:56.990 align:start position:0% byes um yes so we can continue so basically<00:51:54.839> once<00:51:55.079> you 00:51:56.990 --> 00:51:57.000 align:start position:0% basically once you 00:51:57.000 --> 00:52:00.109 align:start position:0% basically once you uh<00:51:57.920> yeah<00:51:58.119> once<00:51:58.319> you<00:51:58.520> are<00:51:58.760> going<00:51:59.000> to<00:51:59.319> compare 00:52:00.109 --> 00:52:00.119 align:start position:0% uh yeah once you are going to compare 00:52:00.119 --> 00:52:02.589 align:start position:0% uh yeah once you are going to compare here<00:52:00.760> and<00:52:01.079> then<00:52:01.440> you<00:52:01.599> have<00:52:01.880> like<00:52:02.119> as<00:52:02.240> I<00:52:02.359> said 00:52:02.589 --> 00:52:02.599 align:start position:0% here and then you have like as I said 00:52:02.599 --> 00:52:04.349 align:start position:0% here and then you have like as I said like<00:52:02.760> two<00:52:03.000> different<00:52:03.680> uh<00:52:03.839> cases<00:52:04.200> two 00:52:04.349 --> 00:52:04.359 align:start position:0% like two different uh cases two 00:52:04.359 --> 00:52:06.829 align:start position:0% like two different uh cases two different<00:52:05.040> scenarios<00:52:06.040> either<00:52:06.440> you<00:52:06.559> can 00:52:06.829 --> 00:52:06.839 align:start position:0% different scenarios either you can 00:52:06.839 --> 00:52:09.789 align:start position:0% different scenarios either you can revert<00:52:07.760> so<00:52:08.240> we<00:52:08.359> are<00:52:08.599> just<00:52:08.839> reverting<00:52:09.440> like<00:52:09.640> the 00:52:09.789 --> 00:52:09.799 align:start position:0% revert so we are just reverting like the 00:52:09.799 --> 00:52:13.030 align:start position:0% revert so we are just reverting like the the<00:52:09.880> hard<00:52:10.160> way<00:52:11.160> oh<00:52:11.520> we<00:52:11.680> we<00:52:11.799> might<00:52:12.040> be<00:52:12.359> going<00:52:12.720> to 00:52:13.030 --> 00:52:13.040 align:start position:0% the hard way oh we we might be going to 00:52:13.040 --> 00:52:14.470 align:start position:0% the hard way oh we we might be going to our<00:52:13.319> macro 00:52:14.470 --> 00:52:14.480 align:start position:0% our macro 00:52:14.480 --> 00:52:18.470 align:start position:0% our macro here<00:52:15.480> and<00:52:15.720> the<00:52:15.880> macro<00:52:16.280> is<00:52:16.559> kind<00:52:16.720> of<00:52:17.200> simple<00:52:18.200> so 00:52:18.470 --> 00:52:18.480 align:start position:0% here and the macro is kind of simple so 00:52:18.480 --> 00:52:23.549 align:start position:0% here and the macro is kind of simple so we<00:52:18.599> know<00:52:18.920> that<00:52:19.119> we<00:52:19.319> have<00:52:19.640> like<00:52:20.559> two<00:52:21.079> uin<00:52:22.079> uh<00:52:22.559> 256 00:52:23.549 --> 00:52:23.559 align:start position:0% we know that we have like two uin uh 256 00:52:23.559 --> 00:52:25.829 align:start position:0% we know that we have like two uin uh 256 that<00:52:23.720> we<00:52:23.880> need<00:52:24.040> to<00:52:24.359> have<00:52:24.880> into<00:52:25.160> the<00:52:25.359> stack 00:52:25.829 --> 00:52:25.839 align:start position:0% that we need to have into the stack 00:52:25.839 --> 00:52:28.430 align:start position:0% that we need to have into the stack because<00:52:26.119> we<00:52:26.240> want<00:52:26.520> want<00:52:26.760> to<00:52:27.760> add<00:52:28.040> them 00:52:28.430 --> 00:52:28.440 align:start position:0% because we want want to add them 00:52:28.440 --> 00:52:31.190 align:start position:0% because we want want to add them together<00:52:28.880> and<00:52:29.319> return<00:52:29.680> the<00:52:29.880> sum<00:52:30.200> of<00:52:30.400> these<00:52:30.599> two 00:52:31.190 --> 00:52:31.200 align:start position:0% together and return the sum of these two 00:52:31.200 --> 00:52:33.589 align:start position:0% together and return the sum of these two values<00:52:31.920> so<00:52:32.160> we<00:52:32.240> are<00:52:32.440> going<00:52:32.640> to<00:52:32.839> do<00:52:33.119> the<00:52:33.280> exact 00:52:33.589 --> 00:52:33.599 align:start position:0% values so we are going to do the exact 00:52:33.599 --> 00:52:36.430 align:start position:0% values so we are going to do the exact same<00:52:33.799> thing<00:52:34.040> as<00:52:34.200> we<00:52:34.359> did<00:52:34.760> here<00:52:35.559> uh<00:52:35.680> I<00:52:35.760> mean 00:52:36.430 --> 00:52:36.440 align:start position:0% same thing as we did here uh I mean 00:52:36.440 --> 00:52:37.789 align:start position:0% same thing as we did here uh I mean called<00:52:36.760> the<00:52:36.880> same 00:52:37.789 --> 00:52:37.799 align:start position:0% called the same 00:52:37.799 --> 00:52:40.670 align:start position:0% called the same function<00:52:38.799> and<00:52:38.960> so<00:52:39.640> in<00:52:39.839> this<00:52:40.040> case<00:52:40.319> we<00:52:40.440> know 00:52:40.670 --> 00:52:40.680 align:start position:0% function and so in this case we know 00:52:40.680 --> 00:52:43.829 align:start position:0% function and so in this case we know that<00:52:40.880> the<00:52:41.040> four<00:52:41.599> first<00:52:42.200> bytes<00:52:43.040> or<00:52:43.599> the 00:52:43.829 --> 00:52:43.839 align:start position:0% that the four first bytes or the 00:52:43.839 --> 00:52:47.870 align:start position:0% that the four first bytes or the function<00:52:44.839> uh<00:52:45.040> signature<00:52:46.000> so<00:52:46.559> we<00:52:46.839> are<00:52:47.160> going<00:52:47.440> to 00:52:47.870 --> 00:52:47.880 align:start position:0% function uh signature so we are going to 00:52:47.880 --> 00:52:51.750 align:start position:0% function uh signature so we are going to ignore<00:52:48.400> them<00:52:49.240> and<00:52:49.480> we<00:52:49.599> say<00:52:50.040> okay<00:52:50.559> put<00:52:51.200> into<00:52:51.520> the 00:52:51.750 --> 00:52:51.760 align:start position:0% ignore them and we say okay put into the 00:52:51.760 --> 00:52:55.510 align:start position:0% ignore them and we say okay put into the stack<00:52:52.680> so<00:52:53.319> called<00:52:53.680> Data<00:52:54.000> load<00:52:54.680> but<00:52:55.000> put<00:52:55.240> into 00:52:55.510 --> 00:52:55.520 align:start position:0% stack so called Data load but put into 00:52:55.520 --> 00:53:00.190 align:start position:0% stack so called Data load but put into the<00:52:55.720> stack<00:52:56.280> the<00:52:56.599> C<00:52:57.000> data<00:52:58.000> starting<00:52:58.839> at<00:52:59.040> the<00:52:59.240> by 00:53:00.190 --> 00:53:00.200 align:start position:0% the stack the C data starting at the by 00:53:00.200 --> 00:53:03.270 align:start position:0% the stack the C data starting at the by uh<00:53:00.359> four<00:53:00.960> so<00:53:01.160> ignore<00:53:01.599> the<00:53:01.799> first<00:53:02.319> four<00:53:02.839> bytes 00:53:03.270 --> 00:53:03.280 align:start position:0% uh four so ignore the first four bytes 00:53:03.280 --> 00:53:06.349 align:start position:0% uh four so ignore the first four bytes and<00:53:03.480> then<00:53:03.720> put<00:53:04.440> uh<00:53:04.880> the<00:53:05.000> call<00:53:05.319> data<00:53:05.960> so<00:53:06.200> this 00:53:06.349 --> 00:53:06.359 align:start position:0% and then put uh the call data so this 00:53:06.359 --> 00:53:10.349 align:start position:0% and then put uh the call data so this will<00:53:06.640> take<00:53:07.160> 32<00:53:08.000> bytes<00:53:09.000> of<00:53:09.240> call<00:53:09.599> data<00:53:10.000> and<00:53:10.200> put 00:53:10.349 --> 00:53:10.359 align:start position:0% will take 32 bytes of call data and put 00:53:10.359 --> 00:53:13.670 align:start position:0% will take 32 bytes of call data and put it<00:53:10.520> into<00:53:10.720> the<00:53:11.319> stack<00:53:12.319> then<00:53:12.720> we<00:53:12.920> just<00:53:13.119> have<00:53:13.280> to 00:53:13.670 --> 00:53:13.680 align:start position:0% it into the stack then we just have to 00:53:13.680 --> 00:53:16.349 align:start position:0% it into the stack then we just have to compute<00:53:14.680> and<00:53:14.920> we<00:53:15.040> say<00:53:15.440> okay<00:53:15.720> we<00:53:16.000> already 00:53:16.349 --> 00:53:16.359 align:start position:0% compute and we say okay we already 00:53:16.359 --> 00:53:18.950 align:start position:0% compute and we say okay we already loaded<00:53:17.240> four<00:53:17.640> bytes<00:53:18.000> for<00:53:18.319> the<00:53:18.520> function 00:53:18.950 --> 00:53:18.960 align:start position:0% loaded four bytes for the function 00:53:18.960 --> 00:53:23.430 align:start position:0% loaded four bytes for the function signature<00:53:19.920> we<00:53:20.119> already<00:53:20.559> loaded<00:53:21.000> 32<00:53:21.720> bytes<00:53:22.559> for 00:53:23.430 --> 00:53:23.440 align:start position:0% signature we already loaded 32 bytes for 00:53:23.440 --> 00:53:27.030 align:start position:0% signature we already loaded 32 bytes for uh<00:53:23.640> the<00:53:23.799> first<00:53:24.559> parameter<00:53:25.240> the<00:53:25.359> first<00:53:25.760> you<00:53:26.520> 2 00:53:27.030 --> 00:53:27.040 align:start position:0% uh the first parameter the first you 2 00:53:27.040 --> 00:53:31.230 align:start position:0% uh the first parameter the first you 2 56<00:53:28.040> then<00:53:28.440> it<00:53:28.599> looks<00:53:28.920> like<00:53:29.119> it<00:53:29.280> could<00:53:29.559> be<00:53:30.559> 36 00:53:31.230 --> 00:53:31.240 align:start position:0% 56 then it looks like it could be 36 00:53:31.240 --> 00:53:33.470 align:start position:0% 56 then it looks like it could be 36 byte<00:53:31.599> that<00:53:31.760> we<00:53:31.920> already<00:53:32.240> loaded<00:53:32.920> so<00:53:33.200> here's 00:53:33.470 --> 00:53:33.480 align:start position:0% byte that we already loaded so here's 00:53:33.480 --> 00:53:35.390 align:start position:0% byte that we already loaded so here's the<00:53:33.680> value 00:53:35.390 --> 00:53:35.400 align:start position:0% the value 00:53:35.400 --> 00:53:38.670 align:start position:0% the value 36<00:53:36.400> so<00:53:36.640> we<00:53:36.760> are<00:53:36.920> going<00:53:37.119> to<00:53:37.240> say<00:53:37.599> okay<00:53:37.920> you<00:53:38.480> have 00:53:38.670 --> 00:53:38.680 align:start position:0% 36 so we are going to say okay you have 00:53:38.680 --> 00:53:42.349 align:start position:0% 36 so we are going to say okay you have to<00:53:39.400> load<00:53:39.839> into<00:53:40.119> the<00:53:40.440> stack<00:53:41.440> uh<00:53:41.599> the<00:53:41.760> next<00:53:42.040> value 00:53:42.349 --> 00:53:42.359 align:start position:0% to load into the stack uh the next value 00:53:42.359 --> 00:53:46.829 align:start position:0% to load into the stack uh the next value which<00:53:42.520> is<00:53:42.799> located<00:53:43.799> after<00:53:44.280> 36<00:53:45.319> bytes 00:53:46.829 --> 00:53:46.839 align:start position:0% which is located after 36

00:53:57.839 --> 00:53:59.430 align:start position:0% any anyone or maybe I already lost some of<00:53:58.040> you<00:53:58.280> I<00:53:58.359> don't 00:53:59.430 --> 00:53:59.440 align:start position:0% of you I don't 00:53:59.440 --> 00:54:03.990 align:start position:0% of you I don't know<00:54:00.440> so<00:54:01.319> uh<00:54:01.680> back<00:54:02.000> to<00:54:02.520> the<00:54:02.799> first<00:54:03.640> couple<00:54:03.839> of 00:54:03.990 --> 00:54:04.000 align:start position:0% know so uh back to the first couple of 00:54:04.000 --> 00:54:09.230 align:start position:0% know so uh back to the first couple of lines<00:54:04.599> inside<00:54:05.359> main<00:54:06.359> um<00:54:06.880> so<00:54:07.400> I<00:54:07.599> get<00:54:08.079> that<00:54:08.599> we're 00:54:09.230 --> 00:54:09.240 align:start position:0% lines inside main um so I get that we're 00:54:09.240 --> 00:54:12.910 align:start position:0% lines inside main um so I get that we're putting<00:54:10.240> uh<00:54:10.720> the<00:54:11.720> the<00:54:12.000> function<00:54:12.400> signature<00:54:12.799> on 00:54:12.910 --> 00:54:12.920 align:start position:0% putting uh the the function signature on 00:54:12.920 --> 00:54:15.230 align:start position:0% putting uh the the function signature on the<00:54:13.079> stack<00:54:13.960> yep<00:54:14.359> and 00:54:15.230 --> 00:54:15.240 align:start position:0% the stack yep and 00:54:15.240 --> 00:54:18.150 align:start position:0% the stack yep and then<00:54:16.240> so<00:54:16.799> at<00:54:16.920> the<00:54:17.040> end<00:54:17.200> of<00:54:17.280> the<00:54:17.400> second<00:54:17.680> line<00:54:17.960> is 00:54:18.150 --> 00:54:18.160 align:start position:0% then so at the end of the second line is 00:54:18.160 --> 00:54:22.750 align:start position:0% then so at the end of the second line is that<00:54:18.720> uh<00:54:19.000> if<00:54:19.160> it's<00:54:19.720> equal<00:54:20.720> then<00:54:21.040> compute<00:54:21.760> jump 00:54:22.750 --> 00:54:22.760 align:start position:0% that uh if it's equal then compute jump 00:54:22.760 --> 00:54:25.150 align:start position:0% that uh if it's equal then compute jump or<00:54:23.280> it<00:54:23.680> or<00:54:23.920> does<00:54:24.040> it<00:54:24.240> say<00:54:24.520> if<00:54:24.640> it's<00:54:24.839> equal 00:54:25.150 --> 00:54:25.160 align:start position:0% or it or does it say if it's equal 00:54:25.160 --> 00:54:27.510 align:start position:0% or it or does it say if it's equal compute<00:54:25.839> I<00:54:25.960> I<00:54:26.040> guess<00:54:26.640> I'm<00:54:26.760> getting<00:54:27.040> confused<00:54:27.400> a 00:54:27.510 --> 00:54:27.520 align:start position:0% compute I I guess I'm getting confused a 00:54:27.520 --> 00:54:29.710 align:start position:0% compute I I guess I'm getting confused a little<00:54:27.640> bit<00:54:28.119> the<00:54:28.240> naming<00:54:28.640> conventions<00:54:29.520> and 00:54:29.710 --> 00:54:29.720 align:start position:0% little bit the naming conventions and 00:54:29.720 --> 00:54:31.630 align:start position:0% little bit the naming conventions and like<00:54:29.839> you've<00:54:30.079> got<00:54:30.400> you<00:54:30.480> know<00:54:30.760> the<00:54:31.280> you're 00:54:31.630 --> 00:54:31.640 align:start position:0% like you've got you know the you're 00:54:31.640 --> 00:54:33.390 align:start position:0% like you've got you know the you're defining<00:54:32.119> function<00:54:32.559> compute<00:54:33.000> and<00:54:33.119> then<00:54:33.240> you 00:54:33.390 --> 00:54:33.400 align:start position:0% defining function compute and then you 00:54:33.400 --> 00:54:37.470 align:start position:0% defining function compute and then you also<00:54:33.720> have<00:54:34.160> a<00:54:34.359> label<00:54:34.880> compute<00:54:35.440> and<00:54:35.680> so<00:54:36.480> yeah 00:54:37.470 --> 00:54:37.480 align:start position:0% also have a label compute and so yeah 00:54:37.480 --> 00:54:40.990 align:start position:0% also have a label compute and so yeah don't<00:54:38.280> I'll<00:54:38.480> explain<00:54:38.880> so<00:54:39.680> basically<00:54:40.680> yeah 00:54:40.990 --> 00:54:41.000 align:start position:0% don't I'll explain so basically yeah 00:54:41.000 --> 00:54:43.870 align:start position:0% don't I'll explain so basically yeah okay<00:54:41.440> I<00:54:41.680> I<00:54:42.119> I<00:54:42.599> understand<00:54:42.799> what<00:54:42.920> you<00:54:43.000> mean<00:54:43.440> okay 00:54:43.870 --> 00:54:43.880 align:start position:0% okay I I I understand what you mean okay 00:54:43.880 --> 00:54:46.510 align:start position:0% okay I I I understand what you mean okay so<00:54:44.359> yeah<00:54:44.680> the<00:54:44.839> the<00:54:44.960> naming<00:54:45.440> was<00:54:45.680> maybe<00:54:46.240> a<00:54:46.359> bit 00:54:46.510 --> 00:54:46.520 align:start position:0% so yeah the the naming was maybe a bit 00:54:46.520 --> 00:54:49.270 align:start position:0% so yeah the the naming was maybe a bit wrong<00:54:46.839> but<00:54:47.040> basically<00:54:47.839> here<00:54:48.200> compute<00:54:48.760> we<00:54:48.960> have 00:54:49.270 --> 00:54:49.280 align:start position:0% wrong but basically here compute we have 00:54:49.280 --> 00:54:50.430 align:start position:0% wrong but basically here compute we have our 00:54:50.430 --> 00:54:50.440 align:start position:0% our 00:54:50.440 --> 00:54:53.430 align:start position:0% our function<00:54:51.440> and<00:54:51.640> this<00:54:51.760> is<00:54:51.960> only<00:54:52.319> related<00:54:52.760> to<00:54:53.040> to 00:54:53.430 --> 00:54:53.440 align:start position:0% function and this is only related to to 00:54:53.440 --> 00:54:57.510 align:start position:0% function and this is only related to to this<00:54:54.440> this<00:54:54.760> and<00:54:55.040> this<00:54:55.280> are<00:54:55.599> related 00:54:57.510 --> 00:54:57.520 align:start position:0% this this and this are related 00:54:57.520 --> 00:55:00.789 align:start position:0% this this and this are related that's<00:54:57.760> it<00:54:58.680> and<00:54:58.960> then<00:54:59.400> this<00:54:59.760> compute<00:55:00.400> is<00:55:00.640> the 00:55:00.789 --> 00:55:00.799 align:start position:0% that's it and then this compute is the 00:55:00.799 --> 00:55:03.789 align:start position:0% that's it and then this compute is the jump<00:55:01.160> label<00:55:01.920> that<00:55:02.079> we<00:55:02.200> are<00:55:02.440> defining<00:55:03.040> here<00:55:03.520> so 00:55:03.789 --> 00:55:03.799 align:start position:0% jump label that we are defining here so 00:55:03.799 --> 00:55:06.710 align:start position:0% jump label that we are defining here so these<00:55:04.000> two<00:55:04.680> are<00:55:04.960> related<00:55:05.559> but<00:55:05.839> that<00:55:06.440> that 00:55:06.710 --> 00:55:06.720 align:start position:0% these two are related but that that 00:55:06.720 --> 00:55:11.069 align:start position:0% these two are related but that that that's<00:55:06.960> it<00:55:07.640> there<00:55:07.760> are<00:55:07.960> no<00:55:08.200> other 00:55:11.069 --> 00:55:11.079 align:start position:0% 00:55:11.079 --> 00:55:14.710 align:start position:0% relationship<00:55:12.079> um<00:55:12.720> and<00:55:12.920> so<00:55:13.559> okay<00:55:14.040> sorry<00:55:14.400> one 00:55:14.710 --> 00:55:14.720 align:start position:0% relationship um and so okay sorry one 00:55:14.720 --> 00:55:16.750 align:start position:0% relationship um and so okay sorry one final<00:55:15.000> thing<00:55:15.119> on<00:55:15.280> that<00:55:15.480> so<00:55:16.119> where<00:55:16.240> it's<00:55:16.400> doing 00:55:16.750 --> 00:55:16.760 align:start position:0% final thing on that so where it's doing 00:55:16.760 --> 00:55:19.309 align:start position:0% final thing on that so where it's doing the<00:55:17.319> the<00:55:17.640> equals<00:55:18.640> uh<00:55:18.760> does<00:55:18.920> it<00:55:19.040> know 00:55:19.309 --> 00:55:19.319 align:start position:0% the the equals uh does it know 00:55:19.319 --> 00:55:20.990 align:start position:0% the the equals uh does it know automatically<00:55:19.880> to<00:55:20.079> just<00:55:20.359> pick<00:55:20.559> the<00:55:20.680> first<00:55:20.839> one 00:55:20.990 --> 00:55:21.000 align:start position:0% automatically to just pick the first one 00:55:21.000 --> 00:55:22.270 align:start position:0% automatically to just pick the first one off<00:55:21.160> the<00:55:21.280> stack<00:55:21.520> and<00:55:21.599> then<00:55:21.720> compare<00:55:22.000> it<00:55:22.079> to 00:55:22.270 --> 00:55:22.280 align:start position:0% off the stack and then compare it to 00:55:22.280 --> 00:55:24.470 align:start position:0% off the stack and then compare it to function<00:55:22.720> signature<00:55:23.119> compute<00:55:23.640> so<00:55:23.920> because 00:55:24.470 --> 00:55:24.480 align:start position:0% function signature compute so because 00:55:24.480 --> 00:55:26.990 align:start position:0% function signature compute so because here<00:55:24.720> we<00:55:24.880> loaded<00:55:25.280> like<00:55:25.440> the<00:55:25.640> function<00:55:25.960> sign 00:55:26.990 --> 00:55:27.000 align:start position:0% here we loaded like the function sign 00:55:27.000 --> 00:55:29.710 align:start position:0% here we loaded like the function sign from<00:55:27.200> the<00:55:27.359> call<00:55:27.640> data<00:55:28.200> so<00:55:28.359> we<00:55:28.520> have<00:55:28.760> like<00:55:29.559> at 00:55:29.710 --> 00:55:29.720 align:start position:0% from the call data so we have like at 00:55:29.720 --> 00:55:31.589 align:start position:0% from the call data so we have like at the<00:55:29.880> top<00:55:30.079> of<00:55:30.240> the<00:55:30.400> stack<00:55:31.039> we<00:55:31.160> have<00:55:31.359> one 00:55:31.589 --> 00:55:31.599 align:start position:0% the top of the stack we have one 00:55:31.599 --> 00:55:33.670 align:start position:0% the top of the stack we have one function<00:55:32.119> signature<00:55:33.000> the<00:55:33.119> one<00:55:33.319> that<00:55:33.520> the 00:55:33.670 --> 00:55:33.680 align:start position:0% function signature the one that the 00:55:33.680 --> 00:55:37.109 align:start position:0% function signature the one that the sender<00:55:34.200> gave<00:55:34.480> us<00:55:35.319> and<00:55:35.799> then<00:55:36.160> here<00:55:36.799> we<00:55:36.960> are 00:55:37.109 --> 00:55:37.119 align:start position:0% sender gave us and then here we are 00:55:37.119 --> 00:55:39.349 align:start position:0% sender gave us and then here we are loading<00:55:37.599> we<00:55:37.720> are<00:55:37.880> putting<00:55:38.160> into<00:55:38.400> the<00:55:38.599> stack 00:55:39.349 --> 00:55:39.359 align:start position:0% loading we are putting into the stack 00:55:39.359 --> 00:55:42.270 align:start position:0% loading we are putting into the stack our<00:55:39.680> own<00:55:40.000> function<00:55:40.559> signature<00:55:41.559> so<00:55:41.960> when<00:55:42.119> we 00:55:42.270 --> 00:55:42.280 align:start position:0% our own function signature so when we 00:55:42.280 --> 00:55:46.029 align:start position:0% our own function signature so when we are<00:55:42.520> calling<00:55:43.520> uh<00:55:43.880> equal<00:55:44.880> it<00:55:45.000> will<00:55:45.200> say<00:55:45.559> okay<00:55:45.839> I 00:55:46.029 --> 00:55:46.039 align:start position:0% are calling uh equal it will say okay I 00:55:46.039 --> 00:55:48.390 align:start position:0% are calling uh equal it will say okay I need<00:55:46.559> two<00:55:47.200> elements<00:55:47.640> from<00:55:47.799> the<00:55:48.000> stack<00:55:48.240> two 00:55:48.390 --> 00:55:48.400 align:start position:0% need two elements from the stack two 00:55:48.400 --> 00:55:50.029 align:start position:0% need two elements from the stack two values<00:55:48.720> from<00:55:48.880> the<00:55:49.039> stack<00:55:49.520> and<00:55:49.680> we'll<00:55:49.880> just 00:55:50.029 --> 00:55:50.039 align:start position:0% values from the stack and we'll just 00:55:50.039 --> 00:55:52.630 align:start position:0% values from the stack and we'll just take<00:55:50.319> like<00:55:50.480> the<00:55:50.599> two<00:55:50.799> first<00:55:51.119> values<00:55:51.880> which<00:55:52.079> are 00:55:52.630 --> 00:55:52.640 align:start position:0% take like the two first values which are 00:55:52.640 --> 00:55:55.549 align:start position:0% take like the two first values which are the<00:55:52.799> values<00:55:53.119> we<00:55:53.280> need<00:55:54.119> and<00:55:54.440> then<00:55:55.000> so<00:55:55.200> we<00:55:55.359> have 00:55:55.549 --> 00:55:55.559 align:start position:0% the values we need and then so we have 00:55:55.559 --> 00:55:58.430 align:start position:0% the values we need and then so we have into<00:55:55.880> the<00:55:56.039> stack<00:55:56.440> like<00:55:56.680> either<00:55:56.960> one<00:55:57.319> or<00:55:57.640> zero 00:55:58.430 --> 00:55:58.440 align:start position:0% into the stack like either one or zero 00:55:58.440 --> 00:56:01.829 align:start position:0% into the stack like either one or zero and<00:55:58.599> we<00:55:58.720> say<00:55:59.160> okay<00:55:59.520> we<00:56:00.160> might<00:56:00.400> want<00:56:00.599> to<00:56:00.839> go<00:56:00.960> to 00:56:01.829 --> 00:56:01.839 align:start position:0% and we say okay we might want to go to 00:56:01.839 --> 00:56:04.630 align:start position:0% and we say okay we might want to go to the<00:56:02.079> compute<00:56:02.720> jump<00:56:03.079> label<00:56:03.559> which<00:56:03.680> is<00:56:03.920> here<00:56:04.520> and 00:56:04.630 --> 00:56:04.640 align:start position:0% the compute jump label which is here and 00:56:04.640 --> 00:56:08.430 align:start position:0% the compute jump label which is here and then<00:56:04.799> we<00:56:04.960> say<00:56:05.359> okay<00:56:05.760> go<00:56:05.920> for<00:56:06.160> it<00:56:06.599> but<00:56:06.839> only<00:56:07.440> if 00:56:08.430 --> 00:56:08.440 align:start position:0% then we say okay go for it but only if 00:56:08.440 --> 00:56:11.950 align:start position:0% then we say okay go for it but only if uh<00:56:08.720> we<00:56:08.920> have<00:56:09.359> a<00:56:09.559> one<00:56:10.559> uh<00:56:10.680> if<00:56:10.799> you<00:56:10.960> have<00:56:11.119> a<00:56:11.280> zero 00:56:11.950 --> 00:56:11.960 align:start position:0% uh we have a one uh if you have a zero 00:56:11.960 --> 00:56:15.150 align:start position:0% uh we have a one uh if you have a zero then<00:56:12.720> keep<00:56:12.920> on<00:56:13.280> reading<00:56:13.720> the<00:56:13.880> next<00:56:14.160> code<00:56:14.799> so<00:56:15.039> we 00:56:15.150 --> 00:56:15.160 align:start position:0% then keep on reading the next code so we 00:56:15.160 --> 00:56:17.870 align:start position:0% then keep on reading the next code so we will<00:56:15.440> just<00:56:16.119> keep<00:56:16.319> on<00:56:16.520> reading<00:56:16.920> the<00:56:17.039> next<00:56:17.319> code 00:56:17.870 --> 00:56:17.880 align:start position:0% will just keep on reading the next code 00:56:17.880 --> 00:56:21.190 align:start position:0% will just keep on reading the next code which<00:56:18.000> is<00:56:18.240> just<00:56:18.480> like<00:56:19.480> reverting<00:56:20.480> and<00:56:20.720> revert 00:56:21.190 --> 00:56:21.200 align:start position:0% which is just like reverting and revert 00:56:21.200 --> 00:56:24.270 align:start position:0% which is just like reverting and revert just<00:56:21.559> say<00:56:22.559> uh<00:56:22.799> okay<00:56:23.000> I<00:56:23.119> want<00:56:23.240> to<00:56:23.440> revert<00:56:24.039> do<00:56:24.160> you 00:56:24.270 --> 00:56:24.280 align:start position:0% just say uh okay I want to revert do you 00:56:24.280 --> 00:56:26.309 align:start position:0% just say uh okay I want to revert do you want<00:56:24.440> to<00:56:24.880> return<00:56:25.160> some<00:56:25.400> values<00:56:25.720> from<00:56:25.880> the<00:56:26.000> mem 00:56:26.309 --> 00:56:26.319 align:start position:0% want to return some values from the mem 00:56:26.319 --> 00:56:30.430 align:start position:0% want to return some values from the mem memory<00:56:26.960> but<00:56:27.160> we<00:56:27.359> say<00:56:28.200> yeah<00:56:28.640> return<00:56:29.640> Z<00:56:30.039> like 00:56:30.430 --> 00:56:30.440 align:start position:0% memory but we say yeah return Z like 00:56:30.440 --> 00:56:33.109 align:start position:0% memory but we say yeah return Z like zero<00:56:31.240> value<00:56:31.599> from<00:56:31.839> the<00:56:32.000> memory<00:56:32.720> that<00:56:32.920> that's 00:56:33.109 --> 00:56:33.119 align:start position:0% zero value from the memory that that's 00:56:33.119 --> 00:56:36.870 align:start position:0% zero value from the memory that that's it<00:56:33.520> the<00:56:33.640> the<00:56:33.920> return<00:56:34.160> here<00:56:34.359> is<00:56:34.599> very<00:56:35.280> very 00:56:36.870 --> 00:56:36.880 align:start position:0% it the the return here is very very 00:56:36.880 --> 00:56:43.829 align:start position:0% it the the return here is very very simple<00:56:37.880> uh<00:56:38.359> more<00:56:38.760> questions 00:56:43.829 --> 00:56:43.839 align:start position:0% 00:56:43.839 --> 00:56:48.670 align:start position:0% yes<00:56:44.839> uh<00:56:45.440> yeah<00:56:45.640> basically<00:56:46.480> yeah<00:56:47.119> yeah<00:56:48.119> and<00:56:48.280> so 00:56:48.670 --> 00:56:48.680 align:start position:0% yes uh yeah basically yeah yeah and so 00:56:48.680 --> 00:56:52.549 align:start position:0% yes uh yeah basically yeah yeah and so this<00:56:48.839> is<00:56:49.680> like<00:56:50.680> the<00:56:50.880> most<00:56:51.640> I<00:56:51.720> think<00:56:51.960> convenient 00:56:52.549 --> 00:56:52.559 align:start position:0% this is like the most I think convenient 00:56:52.559 --> 00:56:55.829 align:start position:0% this is like the most I think convenient thing<00:56:53.480> uh<00:56:54.160> when<00:56:54.319> you<00:56:54.480> are<00:56:54.760> like<00:56:55.079> writing<00:56:55.559> stuff 00:56:55.829 --> 00:56:55.839 align:start position:0% thing uh when you are like writing stuff 00:56:55.839 --> 00:56:57.670 align:start position:0% thing uh when you are like writing stuff like<00:56:55.960> this<00:56:56.280> because<00:56:56.720> if<00:56:56.839> you<00:56:56.920> want<00:56:57.079> to<00:56:57.280> try<00:56:57.480> to 00:56:57.670 --> 00:56:57.680 align:start position:0% like this because if you want to try to 00:56:57.680 --> 00:57:00.750 align:start position:0% like this because if you want to try to write<00:56:58.000> like<00:56:58.280> a<00:56:59.000> uh<00:56:59.559> mimic<00:57:00.119> bite<00:57:00.440> code 00:57:00.750 --> 00:57:00.760 align:start position:0% write like a uh mimic bite code 00:57:00.760 --> 00:57:02.990 align:start position:0% write like a uh mimic bite code basically<00:57:01.200> you<00:57:01.400> can<00:57:01.599> you<00:57:02.079> you<00:57:02.240> can<00:57:02.480> write<00:57:02.839> all 00:57:02.990 --> 00:57:03.000 align:start position:0% basically you can you you can write all 00:57:03.000 --> 00:57:06.670 align:start position:0% basically you can you you can write all of<00:57:03.200> this<00:57:03.559> without<00:57:03.960> H<00:57:04.760> but<00:57:05.200> uh<00:57:05.960> uh<00:57:06.119> instead<00:57:06.480> of 00:57:06.670 --> 00:57:06.680 align:start position:0% of this without H but uh uh instead of 00:57:06.680 --> 00:57:10.510 align:start position:0% of this without H but uh uh instead of having<00:57:07.000> like<00:57:07.200> compute<00:57:07.839> here<00:57:08.480> and<00:57:09.039> here<00:57:10.039> uh 00:57:10.510 --> 00:57:10.520 align:start position:0% having like compute here and here uh 00:57:10.520 --> 00:57:11.950 align:start position:0% having like compute here and here uh instead<00:57:10.799> of<00:57:10.960> having<00:57:11.240> something<00:57:11.559> that<00:57:11.680> you<00:57:11.799> can 00:57:11.950 --> 00:57:11.960 align:start position:0% instead of having something that you can 00:57:11.960 --> 00:57:14.589 align:start position:0% instead of having something that you can read<00:57:12.760> you<00:57:12.839> will<00:57:13.039> have<00:57:13.200> to<00:57:13.400> put<00:57:13.640> like<00:57:13.760> a<00:57:13.960> value 00:57:14.589 --> 00:57:14.599 align:start position:0% read you will have to put like a value 00:57:14.599 --> 00:57:17.150 align:start position:0% read you will have to put like a value and<00:57:14.760> this<00:57:14.960> value<00:57:15.240> will<00:57:15.440> be<00:57:15.799> like<00:57:16.119> a<00:57:16.319> location 00:57:17.150 --> 00:57:17.160 align:start position:0% and this value will be like a location 00:57:17.160 --> 00:57:19.430 align:start position:0% and this value will be like a location inside<00:57:17.480> of<00:57:17.640> your<00:57:17.839> code<00:57:18.440> so<00:57:18.640> you<00:57:18.799> will<00:57:19.160> you<00:57:19.280> will 00:57:19.430 --> 00:57:19.440 align:start position:0% inside of your code so you will you will 00:57:19.440 --> 00:57:21.710 align:start position:0% inside of your code so you will you will say<00:57:19.680> for<00:57:19.880> examp<00:57:20.280> for<00:57:20.480> example<00:57:20.920> sorry<00:57:21.440> I<00:57:21.559> want 00:57:21.710 --> 00:57:21.720 align:start position:0% say for examp for example sorry I want 00:57:21.720 --> 00:57:25.710 align:start position:0% say for examp for example sorry I want to<00:57:21.880> go<00:57:22.079> to<00:57:22.599> uh<00:57:22.839> like<00:57:23.119> the<00:57:23.880> the<00:57:24.440> in<00:57:24.640> my<00:57:24.880> code<00:57:25.440> to 00:57:25.710 --> 00:57:25.720 align:start position:0% to go to uh like the the in my code to 00:57:25.720 --> 00:57:27.630 align:start position:0% to go to uh like the the in my code to the<00:57:26.240> location<00:57:26.799> I 00:57:27.630 --> 00:57:27.640 align:start position:0% the location I 00:57:27.640 --> 00:57:31.109 align:start position:0% the location I like<00:57:28.680> 148<00:57:29.680> but<00:57:29.880> if<00:57:30.000> you<00:57:30.160> add<00:57:30.359> more<00:57:30.599> code<00:57:30.920> here 00:57:31.109 --> 00:57:31.119 align:start position:0% like 148 but if you add more code here 00:57:31.119 --> 00:57:33.309 align:start position:0% like 148 but if you add more code here then<00:57:31.240> you<00:57:31.400> have<00:57:31.520> to<00:57:31.720> change<00:57:32.480> this<00:57:32.760> value<00:57:33.200> you 00:57:33.309 --> 00:57:33.319 align:start position:0% then you have to change this value you 00:57:33.319 --> 00:57:38.150 align:start position:0% then you have to change this value you know<00:57:34.160> so<00:57:34.440> this<00:57:34.839> like<00:57:35.520> this<00:57:35.640> is<00:57:35.920> just<00:57:36.720> uh<00:57:37.720> for<00:57:37.960> us 00:57:38.150 --> 00:57:38.160 align:start position:0% know so this like this is just uh for us 00:57:38.160 --> 00:57:40.710 align:start position:0% know so this like this is just uh for us to<00:57:38.359> be<00:57:38.520> able<00:57:38.760> to<00:57:39.000> do<00:57:39.240> this<00:57:39.480> like<00:57:39.680> a<00:57:39.880> very<00:57:40.359> in<00:57:40.520> a 00:57:40.710 --> 00:57:40.720 align:start position:0% to be able to do this like a very in a 00:57:40.720 --> 00:57:45.069 align:start position:0% to be able to do this like a very in a convenient<00:57:41.280> way<00:57:42.400> um<00:57:43.400> yes<00:57:43.599> so<00:57:44.039> we<00:57:44.400> are<00:57:44.680> jumping 00:57:45.069 --> 00:57:45.079 align:start position:0% convenient way um yes so we are jumping 00:57:45.079 --> 00:57:47.990 align:start position:0% convenient way um yes so we are jumping to<00:57:45.359> compute<00:57:46.200> and<00:57:46.480> as<00:57:46.640> I<00:57:46.920> told<00:57:47.160> you<00:57:47.440> just<00:57:47.640> like<00:57:47.880> a 00:57:47.990 --> 00:57:48.000 align:start position:0% to compute and as I told you just like a 00:57:48.000 --> 00:57:51.029 align:start position:0% to compute and as I told you just like a macro<00:57:48.480> so<00:57:48.640> it's<00:57:48.920> very<00:57:49.920> very<00:57:50.280> simple<00:57:50.680> in<00:57:50.839> this 00:57:51.029 --> 00:57:51.039 align:start position:0% macro so it's very very simple in this 00:57:51.039 --> 00:57:54.589 align:start position:0% macro so it's very very simple in this case<00:57:51.680> we<00:57:51.839> are<00:57:52.119> loading<00:57:53.119> our<00:57:53.359> two<00:57:53.640> values<00:57:54.079> here 00:57:54.589 --> 00:57:54.599 align:start position:0% case we are loading our two values here 00:57:54.599 --> 00:57:57.150 align:start position:0% case we are loading our two values here we<00:57:54.720> know<00:57:55.000> that<00:57:55.480> we<00:57:55.599> are<00:57:56.280> have<00:57:56.400> to<00:57:56.640> avoid<00:57:57.000> the 00:57:57.150 --> 00:57:57.160 align:start position:0% we know that we are have to avoid the 00:57:57.160 --> 00:58:00.589 align:start position:0% we know that we are have to avoid the first<00:57:58.039> uh<00:57:58.160> four<00:57:58.520> bytes<00:57:58.920> so<00:57:59.400> this<00:57:59.520> is<00:57:59.760> like<00:58:00.400> the 00:58:00.589 --> 00:58:00.599 align:start position:0% first uh four bytes so this is like the 00:58:00.599 --> 00:58:04.910 align:start position:0% first uh four bytes so this is like the next<00:58:01.000> 32<00:58:01.559> bytes<00:58:02.559> this<00:58:02.720> is<00:58:02.960> the<00:58:03.240> next<00:58:03.920> 32<00:58:04.520> bytes 00:58:04.910 --> 00:58:04.920 align:start position:0% next 32 bytes this is the next 32 bytes 00:58:04.920 --> 00:58:08.950 align:start position:0% next 32 bytes this is the next 32 bytes after<00:58:05.240> the<00:58:05.400> first<00:58:06.319> uh<00:58:06.480> 36<00:58:07.520> bytes<00:58:08.520> and<00:58:08.680> what<00:58:08.839> is 00:58:08.950 --> 00:58:08.960 align:start position:0% after the first uh 36 bytes and what is 00:58:08.960 --> 00:58:11.390 align:start position:0% after the first uh 36 bytes and what is going<00:58:09.119> to<00:58:09.319> happen<00:58:09.599> is<00:58:09.720> that<00:58:09.880> we<00:58:10.000> have<00:58:10.240> value<00:58:10.920> a 00:58:11.390 --> 00:58:11.400 align:start position:0% going to happen is that we have value a 00:58:11.400 --> 00:58:14.390 align:start position:0% going to happen is that we have value a and<00:58:11.720> value<00:58:12.000> B<00:58:12.440> inside<00:58:12.880> of<00:58:13.079> the<00:58:13.280> stack<00:58:13.920> so<00:58:14.119> we 00:58:14.390 --> 00:58:14.400 align:start position:0% and value B inside of the stack so we 00:58:14.400 --> 00:58:17.430 align:start position:0% and value B inside of the stack so we just<00:58:14.559> have<00:58:14.720> to<00:58:14.880> call<00:58:15.280> add<00:58:16.119> and<00:58:16.440> add<00:58:16.720> is<00:58:17.079> exactly 00:58:17.430 --> 00:58:17.440 align:start position:0% just have to call add and add is exactly 00:58:17.440 --> 00:58:19.910 align:start position:0% just have to call add and add is exactly what<00:58:17.559> I<00:58:17.680> showed<00:58:17.960> you<00:58:18.680> earlier<00:58:19.160> so<00:58:19.559> it<00:58:19.680> just 00:58:19.910 --> 00:58:19.920 align:start position:0% what I showed you earlier so it just 00:58:19.920 --> 00:58:22.870 align:start position:0% what I showed you earlier so it just like<00:58:20.280> uh<00:58:21.280> with<00:58:21.559> multiply<00:58:22.240> just<00:58:22.400> taking<00:58:22.720> like 00:58:22.870 --> 00:58:22.880 align:start position:0% like uh with multiply just taking like 00:58:22.880 --> 00:58:24.750 align:start position:0% like uh with multiply just taking like two<00:58:23.079> values<00:58:23.359> from<00:58:23.559> the<00:58:23.720> stack<00:58:24.240> it<00:58:24.359> will<00:58:24.559> add 00:58:24.750 --> 00:58:24.760 align:start position:0% two values from the stack it will add 00:58:24.760 --> 00:58:27.029 align:start position:0% two values from the stack it will add them<00:58:25.079> together<00:58:25.520> and<00:58:25.720> boom<00:58:26.160> they<00:58:26.559> put<00:58:26.839> back 00:58:27.029 --> 00:58:27.039 align:start position:0% them together and boom they put back 00:58:27.039 --> 00:58:28.430 align:start position:0% them together and boom they put back into<00:58:27.319> the 00:58:28.430 --> 00:58:28.440 align:start position:0% into the 00:58:28.440 --> 00:58:31.190 align:start position:0% into the stack<00:58:29.440> and<00:58:29.720> what<00:58:29.880> is<00:58:30.039> going<00:58:30.280> to<00:58:30.480> happen<00:58:30.920> here 00:58:31.190 --> 00:58:31.200 align:start position:0% stack and what is going to happen here 00:58:31.200 --> 00:58:34.270 align:start position:0% stack and what is going to happen here is<00:58:31.559> that<00:58:32.559> it's<00:58:32.839> pretty<00:58:33.119> simple<00:58:33.480> you'll<00:58:33.680> see<00:58:34.119> we 00:58:34.270 --> 00:58:34.280 align:start position:0% is that it's pretty simple you'll see we 00:58:34.280 --> 00:58:37.349 align:start position:0% is that it's pretty simple you'll see we have<00:58:34.520> one<00:58:34.799> value<00:58:35.240> into<00:58:35.559> the<00:58:35.720> stack<00:58:36.680> and<00:58:37.079> well 00:58:37.349 --> 00:58:37.359 align:start position:0% have one value into the stack and well 00:58:37.359 --> 00:58:39.710 align:start position:0% have one value into the stack and well we<00:58:37.640> now<00:58:37.799> we<00:58:37.920> want<00:58:38.079> to<00:58:38.480> return<00:58:38.720> it<00:58:39.240> because<00:58:39.599> we 00:58:39.710 --> 00:58:39.720 align:start position:0% we now we want to return it because we 00:58:39.720 --> 00:58:41.910 align:start position:0% we now we want to return it because we did<00:58:39.920> all<00:58:40.079> of<00:58:40.319> this<00:58:40.680> but<00:58:40.839> now<00:58:41.000> we<00:58:41.119> need<00:58:41.280> to 00:58:41.910 --> 00:58:41.920 align:start position:0% did all of this but now we need to 00:58:41.920 --> 00:58:45.870 align:start position:0% did all of this but now we need to return<00:58:42.200> our<00:58:42.480> value<00:58:43.200> so<00:58:43.960> return<00:58:44.359> here<00:58:45.319> is<00:58:45.559> very 00:58:45.870 --> 00:58:45.880 align:start position:0% return our value so return here is very 00:58:45.880 --> 00:58:49.190 align:start position:0% return our value so return here is very simple<00:58:46.760> uh<00:58:46.880> you<00:58:47.000> can<00:58:47.200> only<00:58:47.880> return<00:58:48.160> stuff<00:58:48.680> from 00:58:49.190 --> 00:58:49.200 align:start position:0% simple uh you can only return stuff from 00:58:49.200 --> 00:58:52.470 align:start position:0% simple uh you can only return stuff from the<00:58:49.640> memory<00:58:50.400> so<00:58:50.599> we<00:58:50.760> have<00:58:50.960> to<00:58:51.240> put<00:58:51.599> our<00:58:52.319> uh 00:58:52.470 --> 00:58:52.480 align:start position:0% the memory so we have to put our uh 00:58:52.480 --> 00:58:55.789 align:start position:0% the memory so we have to put our uh result<00:58:53.440> the<00:58:53.920> the<00:58:54.079> sum<00:58:54.520> that<00:58:54.680> we<00:58:54.839> just<00:58:55.079> computed 00:58:55.789 --> 00:58:55.799 align:start position:0% result the the sum that we just computed 00:58:55.799 --> 00:58:58.309 align:start position:0% result the the sum that we just computed in<00:58:56.119> to<00:58:56.240> the<00:58:56.359> memory<00:58:56.880> it's<00:58:57.119> very<00:58:57.400> simple<00:58:58.039> we<00:58:58.160> are 00:58:58.309 --> 00:58:58.319 align:start position:0% in to the memory it's very simple we are 00:58:58.319 --> 00:59:01.390 align:start position:0% in to the memory it's very simple we are going<00:58:58.520> to<00:58:58.680> use<00:58:58.880> the<00:58:59.119> M<00:58:59.400> store<00:59:00.039> up<00:59:00.359> code<00:59:00.960> and<00:59:01.160> M 00:59:01.390 --> 00:59:01.400 align:start position:0% going to use the M store up code and M 00:59:01.400 --> 00:59:04.789 align:start position:0% going to use the M store up code and M store<00:59:01.760> takes<00:59:02.520> one<00:59:02.920> value<00:59:03.319> here<00:59:04.319> and<00:59:04.559> one 00:59:04.789 --> 00:59:04.799 align:start position:0% store takes one value here and one 00:59:04.799 --> 00:59:07.150 align:start position:0% store takes one value here and one location<00:59:05.480> inside<00:59:05.799> of<00:59:05.960> the<00:59:06.119> memory<00:59:06.880> and<00:59:07.000> then 00:59:07.150 --> 00:59:07.160 align:start position:0% location inside of the memory and then 00:59:07.160 --> 00:59:09.670 align:start position:0% location inside of the memory and then we<00:59:07.280> just<00:59:07.440> call<00:59:07.680> M<00:59:07.920> store<00:59:08.480> so<00:59:08.799> what<00:59:09.000> we've<00:59:09.280> done 00:59:09.670 --> 00:59:09.680 align:start position:0% we just call M store so what we've done 00:59:09.680 --> 00:59:14.750 align:start position:0% we just call M store so what we've done here<00:59:10.039> that<00:59:10.640> we<00:59:10.880> are<00:59:11.280> putting<00:59:12.200> here<00:59:13.359> um<00:59:14.359> at<00:59:14.599> the 00:59:14.750 --> 00:59:14.760 align:start position:0% here that we are putting here um at the 00:59:14.760 --> 00:59:17.670 align:start position:0% here that we are putting here um at the location<00:59:15.400> zero<00:59:16.200> the<00:59:16.400> value<00:59:16.680> of<00:59:16.880> AD<00:59:17.359> so<00:59:17.559> the 00:59:17.670 --> 00:59:17.680 align:start position:0% location zero the value of AD so the 00:59:17.680 --> 00:59:21.910 align:start position:0% location zero the value of AD so the value<00:59:17.920> of<00:59:18.079> AD<00:59:18.359> can<00:59:18.559> be<00:59:19.000> anything<00:59:19.920> up<00:59:20.160> to<00:59:20.720> 32<00:59:21.720> uh 00:59:21.910 --> 00:59:21.920 align:start position:0% value of AD can be anything up to 32 uh 00:59:21.920 --> 00:59:24.789 align:start position:0% value of AD can be anything up to 32 uh bytes<00:59:22.240> obviously<00:59:22.640> but<00:59:22.760> it<00:59:22.839> can<00:59:23.000> be<00:59:23.799> anything 00:59:24.789 --> 00:59:24.799 align:start position:0% bytes obviously but it can be anything 00:59:24.799 --> 00:59:26.589 align:start position:0% bytes obviously but it can be anything and<00:59:25.079> yeah<00:59:25.280> we<00:59:25.440> have<00:59:25.720> like<00:59:26.119> value<00:59:26.359> in<00:59:26.480> the 00:59:26.589 --> 00:59:26.599 align:start position:0% and yeah we have like value in the 00:59:26.599 --> 00:59:30.670 align:start position:0% and yeah we have like value in the memory 00:59:30.670 --> 00:59:30.680 align:start position:0% 00:59:30.680 --> 00:59:34.430 align:start position:0% yes<00:59:31.680> wait<00:59:31.839> for<00:59:32.039>

00:59:34.440 --> 00:59:36.349 align:start position:0% yes wait for the mic sorry isn't there a cost<00:59:34.720> for<00:59:34.920> putting<00:59:35.240> that<00:59:35.480> value<00:59:35.720> in<00:59:35.920> memory<00:59:36.280> I 00:59:36.349 --> 00:59:36.359 align:start position:0% cost for putting that value in memory I 00:59:36.359 --> 00:59:38.710 align:start position:0% cost for putting that value in memory I mean<00:59:36.520> it's<00:59:36.720> not<00:59:37.000> like<00:59:37.480> yeah<00:59:37.640> obviously<00:59:38.280> yeah 00:59:38.710 --> 00:59:38.720 align:start position:0% mean it's not like yeah obviously yeah 00:59:38.720 --> 00:59:40.230 align:start position:0% mean it's not like yeah obviously yeah but<00:59:38.920> why<00:59:39.039> not<00:59:39.280>

position:0% are okay we are here so basically you 01:00:04.440 --> 01:00:06.710 align:start position:0% are okay we are here so basically you you<01:00:04.559> can<01:00:04.720> see<01:00:05.000> like<01:00:05.440> uh<01:00:05.640> we<01:00:05.760> don't<01:00:06.000> have<01:00:06.200> the 01:00:06.710 --> 01:00:06.720 align:start position:0% you can see like uh we don't have the 01:00:06.720 --> 01:00:09.670 align:start position:0% you can see like uh we don't have the return<01:00:07.720> um<01:00:08.000> function<01:00:08.559> here 01:00:09.670 --> 01:00:09.680 align:start position:0% return um function here 01:00:09.680 --> 01:00:12.510 align:start position:0% return um function here obviously<01:00:10.680> uh<01:00:11.319> okay<01:00:11.520> but<01:00:11.640> if<01:00:11.760> you<01:00:12.000> go<01:00:12.160> on<01:00:12.319> this 01:00:12.510 --> 01:00:12.520 align:start position:0% obviously uh okay but if you go on this 01:00:12.520 --> 01:00:16.470 align:start position:0% obviously uh okay but if you go on this website<01:00:13.359> it's<01:00:13.599> evm<01:00:14.799> code<01:00:15.799> you<01:00:15.920> will<01:00:16.039> see<01:00:16.280> like 01:00:16.470 --> 01:00:16.480 align:start position:0% website it's evm code you will see like 01:00:16.480 --> 01:00:20.109 align:start position:0% website it's evm code you will see like all<01:00:16.760> the<01:00:17.319> up<01:00:17.640> codes<01:00:17.960> are<01:00:18.319> explained<01:00:18.920> here<01:00:19.680> and 01:00:20.109 --> 01:00:20.119 align:start position:0% all the up codes are explained here and 01:00:20.119 --> 01:00:21.789 align:start position:0% all the up codes are explained here and you<01:00:20.200> will<01:00:20.359> see<01:00:20.599> like<01:00:20.799> stack<01:00:21.160> input<01:00:21.599> so 01:00:21.789 --> 01:00:21.799 align:start position:0% you will see like stack input so 01:00:21.799 --> 01:00:24.029 align:start position:0% you will see like stack input so basically<01:00:22.720> this<01:00:22.839> is<01:00:23.119> like<01:00:23.559> when<01:00:23.720> I<01:00:23.839> was 01:00:24.029 --> 01:00:24.039 align:start position:0% basically this is like when I was 01:00:24.039 --> 01:00:26.309 align:start position:0% basically this is like when I was talking<01:00:24.440> about<01:00:24.880> the<01:00:25.000> stack<01:00:25.359> this<01:00:25.480> is<01:00:25.640> like 01:00:26.309 --> 01:00:26.319 align:start position:0% talking about the stack this is like 01:00:26.319 --> 01:00:28.870 align:start position:0% talking about the stack this is like what<01:00:26.559> is<01:00:27.000> expected<01:00:28.000> and<01:00:28.160> this<01:00:28.280> is<01:00:28.520> what<01:00:28.680> will 01:00:28.870 --> 01:00:28.880 align:start position:0% what is expected and this is what will 01:00:28.880 --> 01:00:32.390 align:start position:0% what is expected and this is what will be<01:00:29.599> uh<01:00:29.760> left<01:00:30.119> into<01:00:30.400> the<01:00:30.599> stack<01:00:31.119> so<01:00:31.359> in<01:00:31.559> our<01:00:31.880> case 01:00:32.390 --> 01:00:32.400 align:start position:0% be uh left into the stack so in our case 01:00:32.400 --> 01:00:34.789 align:start position:0% be uh left into the stack so in our case we<01:00:32.520> are<01:00:32.920> taking<01:00:33.240> Like<01:00:33.440> A<01:00:33.640> and<01:00:33.799> B<01:00:34.400> and<01:00:34.520> we<01:00:34.640> are 01:00:34.789 --> 01:00:34.799 align:start position:0% we are taking Like A and B and we are 01:00:34.799 --> 01:00:37.910 align:start position:0% we are taking Like A and B and we are adding<01:00:35.160> them<01:00:35.440> so<01:00:35.680> we<01:00:35.880> go<01:00:36.119> from<01:00:36.359> two<01:00:36.920> elements 01:00:37.910 --> 01:00:37.920 align:start position:0% adding them so we go from two elements 01:00:37.920 --> 01:00:40.950 align:start position:0% adding them so we go from two elements uh<01:00:38.720> from<01:00:39.000> two<01:00:39.359> elements<01:00:39.799> to<01:00:40.079> one<01:00:40.359> element<01:00:40.720> into 01:00:40.950 --> 01:00:40.960 align:start position:0% uh from two elements to one element into 01:00:40.960 --> 01:00:42.990 align:start position:0% uh from two elements to one element into the<01:00:41.160> stack<01:00:41.760> and<01:00:41.960> you<01:00:42.039> can<01:00:42.160> see<01:00:42.359> like<01:00:42.799> there<01:00:42.880> is 01:00:42.990 --> 01:00:43.000 align:start position:0% the stack and you can see like there is 01:00:43.000 --> 01:00:45.789 align:start position:0% the stack and you can see like there is a<01:00:43.240> description<01:00:43.960> here<01:00:44.960> and<01:00:45.079> if<01:00:45.200> you<01:00:45.400> go<01:00:45.559> down 01:00:45.789 --> 01:00:45.799 align:start position:0% a description here and if you go down 01:00:45.799

interesting question can 01:00:51.160 --> 01:00:54.750 align:start position:0% this is like a interesting question can you<01:00:52.440> uh 01:00:54.750 --> 01:00:54.760 align:start position:0% you uh 01:00:54.760 --> 01:00:57.309 align:start position:0% you uh yay<01:00:55.760> uh<01:00:56.079> all 01:00:57.309 --> 01:00:57.319 align:start position:0% yay uh all 01:00:57.319 --> 01:01:00.870 align:start position:0% yay uh all right<01:00:58.319> all<01:00:58.559> right<01:00:58.920> let<01:00:59.079> me<01:00:59.359> see 01:01:00.870 --> 01:01:00.880 align:start position:0% right all right let me see 01:01:00.880 --> 01:01:04.510 align:start position:0% right all right let me see evm<01:01:01.880> all<01:01:02.039> right<01:01:02.240> so<01:01:02.799> if<01:01:02.920> you<01:01:03.119> go<01:01:03.400> down<01:01:03.680> here<01:01:04.200> I'm 01:01:04.510 --> 01:01:04.520 align:start position:0% evm all right so if you go down here I'm 01:01:04.520 --> 01:01:06.190 align:start position:0% evm all right so if you go down here I'm not<01:01:04.720> going<01:01:04.880> to<01:01:05.079> take<01:01:05.319> like<01:01:05.440> too<01:01:05.640> much<01:01:05.839> time<01:01:06.000> on 01:01:06.190 --> 01:01:06.200 align:start position:0% not going to take like too much time on 01:01:06.200 --> 01:01:08.789 align:start position:0% not going to take like too much time on this<01:01:06.440> but<01:01:06.720> basically<01:01:07.720> let's<01:01:07.920> do 01:01:08.789 --> 01:01:08.799 align:start position:0% this but basically let's do 01:01:08.799 --> 01:01:12.630 align:start position:0% this but basically let's do research<01:01:09.799> M<01:01:10.119> store<01:01:10.920> here<01:01:11.359> you<01:01:11.480> can<01:01:11.640> see<01:01:11.839> like 01:01:12.630 --> 01:01:12.640 align:start position:0% research M store here you can see like 01:01:12.640 --> 01:01:16.430 align:start position:0% research M store here you can see like um<01:01:13.640> this<01:01:13.760> is<01:01:13.960> explaining<01:01:14.559> how<01:01:15.400> uh<01:01:15.559> M<01:01:15.880> store 01:01:16.430 --> 01:01:16.440 align:start position:0% um this is explaining how uh M store 01:01:16.440 --> 01:01:20.630 align:start position:0% um this is explaining how uh M store works<01:01:17.440> and<01:01:17.680> if<01:01:17.799> you<01:01:17.960> go<01:01:18.160> to<01:01:18.640> uh<01:01:19.520> return<01:01:20.520> you 01:01:20.630 --> 01:01:20.640 align:start position:0% works and if you go to uh return you 01:01:20.640 --> 01:01:22.750 align:start position:0% works and if you go to uh return you will<01:01:20.839> see<01:01:21.160> like 01:01:22.750 --> 01:01:22.760 align:start position:0% will see like 01:01:22.760 --> 01:01:26.829 align:start position:0% will see like uh<01:01:23.799> uh<01:01:24.799> the<01:01:25.039> explanation<01:01:25.960> will<01:01:26.240> it<01:01:26.319> will<01:01:26.559> just 01:01:26.829 --> 01:01:26.839 align:start position:0% uh uh the explanation will it will just 01:01:26.839 --> 01:01:30.109 align:start position:0% uh uh the explanation will it will just tell<01:01:27.079> you<01:01:27.280> okay<01:01:27.480> stack<01:01:28.359> inputs<01:01:29.359> uh<01:01:29.640> so<01:01:29.880> the 01:01:30.109 --> 01:01:30.119 align:start position:0% tell you okay stack inputs uh so the 01:01:30.119 --> 01:01:31.990 align:start position:0% tell you okay stack inputs uh so the definition<01:01:30.599> is<01:01:30.799> like<01:01:31.000> the<01:01:31.160> offset<01:01:31.599> and<01:01:31.799> the 01:01:31.990 --> 01:01:32.000 align:start position:0% definition is like the offset and the 01:01:32.000 --> 01:01:35.390 align:start position:0% definition is like the offset and the size<01:01:32.640> so<01:01:32.839> basically<01:01:33.280> this<01:01:33.400> means<01:01:33.720> that<01:01:34.720> uh<01:01:34.960> we 01:01:35.390 --> 01:01:35.400 align:start position:0% size so basically this means that uh we 01:01:35.400 --> 01:01:39.630 align:start position:0% size so basically this means that uh we need<01:01:35.640> to<01:01:36.160> tell<01:01:37.160> uh<01:01:37.520> where<01:01:38.079> we<01:01:38.240> want<01:01:38.480> to<01:01:39.280> load 01:01:39.630 --> 01:01:39.640 align:start position:0% need to tell uh where we want to load 01:01:39.640 --> 01:01:42.430 align:start position:0% need to tell uh where we want to load the<01:01:39.839> value<01:01:40.160> from<01:01:40.520> so<01:01:40.960> it<01:01:41.440> obviously<01:01:42.000> inside<01:01:42.319> of 01:01:42.430 --> 01:01:42.440 align:start position:0% the value from so it obviously inside of 01:01:42.440 --> 01:01:45.630 align:start position:0% the value from so it obviously inside of the<01:01:43.000> memory<01:01:44.000> and<01:01:44.200> the 01:01:45.630 --> 01:01:45.640 align:start position:0% the memory and the 01:01:45.640 --> 01:01:49.549 align:start position:0% the memory and the size<01:01:46.640> that's<01:01:46.960> uh<01:01:47.200> that<01:01:47.400> that's<01:01:47.640> it<01:01:48.440> so<01:01:48.839> if<01:01:49.039> you 01:01:49.549 --> 01:01:49.559 align:start position:0% size that's uh that that's it so if you 01:01:49.559 --> 01:01:51.670 align:start position:0% size that's uh that that's it so if you can<01:01:49.680> you<01:01:49.880> go<01:01:50.079> back<01:01:50.200> to<01:01:50.440> the<01:01:51.119> can<01:01:51.200> you<01:01:51.359> go<01:01:51.520> back 01:01:51.670 --> 01:01:51.680 align:start position:0% can you go back to the can you go back 01:01:51.680 --> 01:01:56.710 align:start position:0% can you go back to the can you go back to<01:01:51.960> the<01:01:52.599> presentation<01:01:53.480> thank<01:01:54.119> you<01:01:55.119> perfect 01:01:56.710 --> 01:01:56.720 align:start position:0% to the presentation thank you perfect 01:01:56.720 --> 01:01:59.430 align:start position:0% to the

position:0% far uh yeah no wait this is the second 01:02:39.960 --> 01:02:43.269 align:start position:0% far uh yeah no wait this is the second one<01:02:40.960> uh<01:02:41.160> this<01:02:41.279> is<01:02:41.480> the<01:02:41.680> test<01:02:42.400> that's<01:02:42.599> the<01:02:42.760> one 01:02:43.269 --> 01:02:43.279 align:start position:0% one uh this is the test that's the one 01:02:43.279 --> 01:02:45.349 align:start position:0% one uh this is the test that's the one uh<01:02:43.520> yeah<01:02:43.680> that's<01:02:43.839> the<01:02:44.000> right<01:02:44.160> one<01:02:44.680> so<01:02:45.000> yeah<01:02:45.200> and 01:02:45.349 --> 01:02:45.359 align:start position:0% uh yeah that's the right one so yeah and 01:02:45.359 --> 01:02:48.750 align:start position:0% uh yeah that's the right one so yeah and then<01:02:45.640> we<01:02:45.960> have<01:02:46.960> uh<01:02:47.279> yeah<01:02:47.480> as<01:02:47.720> I<01:02:47.880> just<01:02:48.359> just<01:02:48.480> said 01:02:48.750 --> 01:02:48.760 align:start position:0% then we have uh yeah as I just just said 01:02:48.760 --> 01:02:51.789 align:start position:0% then we have uh yeah as I just just said like<01:02:49.200> return<01:02:49.960> so<01:02:50.359> return<01:02:50.559> is<01:02:50.799> expecting<01:02:51.480> two 01:02:51.789 --> 01:02:51.799 align:start position:0% like return so return is expecting two 01:02:51.799 --> 01:02:54.829 align:start position:0% like return so return is expecting two values<01:02:52.680> so<01:02:52.960> we<01:02:53.160> have<01:02:53.720> the<01:02:53.920> first<01:02:54.319> value<01:02:54.680> which 01:02:54.829 --> 01:02:54.839 align:start position:0% values so we have the first value which 01:02:54.839 --> 01:02:58.710 align:start position:0% values so we have the first value which is<01:02:55.000> the<01:02:55.200> size<01:02:56.319> uh<01:02:57.079> what<01:02:57.279> we<01:02:57.400> want<01:02:57.599> to<01:02:58.000> return<01:02:58.520> so 01:02:58.710 --> 01:02:58.720 align:start position:0% is the size uh what we want to return so 01:02:58.720 --> 01:03:01.950 align:start position:0% is the size uh what we want to return so in<01:02:58.920> our<01:02:59.240> case<01:02:59.520> it's<01:02:59.960> 32<01:03:00.760> bytes<01:03:01.319> so<01:03:01.480> it's<01:03:01.680> like 01:03:01.950 --> 01:03:01.960 align:start position:0% in our case it's 32 bytes so it's like 01:03:01.960 --> 01:03:05.549 align:start position:0% in our case it's 32 bytes so it's like 0x<01:03:02.960> 20<01:03:03.440> in<01:03:03.680> exad<01:03:04.039> decimal<01:03:04.880> you<01:03:05.000> will<01:03:05.160> see<01:03:05.359> like 01:03:05.549 --> 01:03:05.559 align:start position:0% 0x 20 in exad decimal you will see like 01:03:05.559 --> 01:03:08.069 align:start position:0% 0x 20 in exad decimal you will see like many<01:03:06.000> have<01:03:06.319> code<01:03:06.880> are<01:03:07.119> return<01:03:07.680> like<01:03:07.799> all<01:03:07.920> the 01:03:08.069 --> 01:03:08.079 align:start position:0% many have code are return like all the 01:03:08.079 --> 01:03:10.349 align:start position:0% many have code are return like all the values<01:03:08.440> are<01:03:08.640> in<01:03:08.880> exad<01:03:09.240> decimal<01:03:10.039> I<01:03:10.160> guess 01:03:10.349 --> 01:03:10.359 align:start position:0% values are in exad decimal I guess 01:03:10.359 --> 01:03:12.269 align:start position:0% values are in exad decimal I guess because<01:03:10.640> it's<01:03:10.960> cooler<01:03:11.559> I<01:03:11.640> don't<01:03:11.839> know<01:03:12.119> but 01:03:12.269 --> 01:03:12.279 align:start position:0% because it's cooler I don't know but 01:03:12.279 --> 01:03:15.150 align:start position:0% because it's cooler I don't know but it's<01:03:12.559> like<01:03:13.039> more<01:03:13.359> by<01:03:13.599> convention<01:03:14.599> so<01:03:14.760> you<01:03:14.880> know 01:03:15.150 --> 01:03:15.160 align:start position:0% it's like more by convention so you know 01:03:15.160 --> 01:03:18.870 align:start position:0% it's like more by convention so you know that<01:03:15.520> you<01:03:15.640> want<01:03:15.799> to<01:03:16.160> return<01:03:16.400> a<01:03:16.720> u<01:03:17.000> in<01:03:17.720> 256<01:03:18.720> so 01:03:18.870 --> 01:03:18.880 align:start position:0% that you want to return a u in 256 so 01:03:18.880 --> 01:03:21.870 align:start position:0% that you want to return a u in 256 so you<01:03:19.000> have<01:03:19.160> to<01:03:19.440> return<01:03:19.720> 32<01:03:20.400> bytes<01:03:21.400> and<01:03:21.599> this<01:03:21.720> is 01:03:21.870 --> 01:03:21.880 align:start position:0% you have to return 32 bytes and this is 01:03:21.880 --> 01:03:24.630 align:start position:0% you have to return 32 bytes and this is the<01:03:22.079> location<01:03:22.640> in<01:03:23.000> memory<01:03:24.000> you<01:03:24.119> can<01:03:24.279> see<01:03:24.520> we 01:03:24.630 --> 01:03:24.640 align:start position:0% the location in memory you can see we 01:03:24.640 --> 01:03:28.950 align:start position:0% the location in memory you can see we just<01:03:24.799> stored<01:03:25.200> it<01:03:25.400> here<01:03:26.160> uh<01:03:26.599> the<01:03:27.240> zero<01:03:27.880> like<01:03:28.240> uh 01:03:28.950 --> 01:03:28.960 align:start position:0% just stored it here uh the zero like uh 01:03:28.960 --> 01:03:32.309 align:start position:0% just stored it here uh the zero like uh like<01:03:29.480> madm<01:03:30.480> um<01:03:30.839> and<01:03:30.960> so<01:03:31.160> we<01:03:31.319> can<01:03:31.520> just<01:03:31.760> like 01:03:32.309 --> 01:03:32.319 align:start position:0% like madm um and so we can just like 01:03:32.319 --> 01:03:34.789 align:start position:0% like madm um and so we can just like call<01:03:32.839> return<01:03:33.240> and<01:03:33.440> and<01:03:33.599> that's<01:03:33.839> it<01:03:34.359> we<01:03:34.559> have 01:03:34.789 --> 01:03:34.799 align:start position:0% call return and and that's it we have 01:03:34.799 --> 01:03:40.470 align:start position:0% call return and and that's it we have our<01:03:35.799> whole<01:03:36.559> contract<01:03:37.559> so<01:03:38.200> if<01:03:38.440> you<01:03:39.359> guys<01:03:40.200> have 01:03:40.470 --> 01:03:40.480 align:start position:0% our whole contract so if you guys have 01:03:40.480 --> 01:03:43.309 align:start position:0% our whole contract so if you guys have the<01:03:40.640> code<01:03:41.000> ready<01:03:41.880> you<01:03:42.039> can<01:03:42.400> try<01:03:42.720> writing<01:03:43.079> a 01:03:43.309 --> 01:03:43.319 align:start position:0% the code ready you can try writing a 01:03:43.319 --> 01:03:45.230 align:start position:0% the code ready you can try writing a test 01:03:45.230 --> 01:03:45.240 align:start position:0% test 01:03:45.240 --> 01:03:48.190 align:start position:0% test actually<01:03:46.240> so<01:03:46.559> this<01:03:46.680> is<01:03:46.880> how<01:03:47.160> tests<01:03:47.640> are 01:03:48.190 --> 01:03:48.200 align:start position:0% actually so this is how tests are 01:03:48.200 --> 01:03:49.870 align:start position:0% actually so this is how tests are working<01:03:48.920> with 01:03:49.870 --> 01:03:49.880 align:start position:0% working with 01:03:49.880 --> 01:03:53.390 align:start position:0% working with fundry<01:03:50.880> uh<01:03:51.559> and<01:03:51.880> half<01:03:52.680> uh<01:03:52.799> so<01:03:52.960> we<01:03:53.119> have 01:03:53.390 --> 01:03:53.400 align:start position:0% fundry uh and half uh so we have 01:03:53.400 --> 01:03:56.430 align:start position:0% fundry uh and half uh so we have something<01:03:53.839> called<01:03:54.160> like<01:03:54.400> a<01:03:54.680> half<01:03:55.079> deployer 01:03:56.430 --> 01:03:56.440 align:start position:0% something called like a half deployer 01:03:56.440 --> 01:03:58.750 align:start position:0% something called like a half deployer and<01:03:56.880> this<01:03:57.039> is<01:03:57.400> pretty<01:03:57.839> convenient<01:03:58.400> because 01:03:58.750 --> 01:03:58.760 align:start position:0% and this is pretty convenient because 01:03:58.760 --> 01:04:02.829 align:start position:0% and this is pretty convenient because it's<01:03:58.960> going<01:03:59.640> to<01:04:00.640> uh<01:04:00.880> take<01:04:01.720> your<01:04:02.240> contract 01:04:02.829 --> 01:04:02.839 align:start position:0% it's going to uh take your contract 01:04:02.839 --> 01:04:04.430 align:start position:0% it's going to uh take your contract compile<01:04:03.160> it<01:04:03.319> for<01:04:03.480> you<01:04:03.680> and<01:04:03.839> then<01:04:03.960> you<01:04:04.039> can<01:04:04.240> just 01:04:04.430 --> 01:04:04.440 align:start position:0% compile it for you and then you can just 01:04:04.440 --> 01:04:06.710 align:start position:0% compile it for you and then you can just deploy<01:04:04.839> it<01:04:04.960> so<01:04:05.680> if<01:04:05.760> you're<01:04:06.119> familiar<01:04:06.559> with 01:04:06.710 --> 01:04:06.720 align:start position:0% deploy it so if you're familiar with 01:04:06.720 --> 01:04:09.230 align:start position:0% deploy it so if you're familiar with Foundry<01:04:07.680> you<01:04:07.839> you<01:04:07.960> will<01:04:08.160> see<01:04:08.440> it's<01:04:08.680> the<01:04:08.880> exact 01:04:09.230 --> 01:04:09.240 align:start position:0% Foundry you you will see it's the exact 01:04:09.240 --> 01:04:12.190 align:start position:0% Foundry you you will see it's the exact same<01:04:09.559> experience<01:04:10.160> as<01:04:10.319> writing<01:04:10.839> regular<01:04:11.319> tests 01:04:12.190 --> 01:04:12.200 align:start position:0% same experience as writing regular tests 01:04:12.200 --> 01:04:15.589 align:start position:0% same experience as writing regular tests very<01:04:12.520> easy<01:04:12.920> very<01:04:13.160> simple<01:04:13.599> very 01:04:15.589 --> 01:04:15.599 align:start position:0% very easy very simple very 01:04:15.599 --> 01:04:18.910 align:start position:0% very easy very simple very convenient<01:04:16.599> uh<01:04:16.880> the<01:04:17.000> only<01:04:17.520> small<01:04:17.960> difference 01:04:18.910 --> 01:04:18.920 align:start position:0% convenient uh the only small difference 01:04:18.920 --> 01:04:20.510 align:start position:0% convenient uh the only small difference I<01:04:19.000> think<01:04:19.200> that<01:04:19.319> might<01:04:19.480> be<01:04:19.599> a<01:04:19.760> better<01:04:20.000> way<01:04:20.119> to<01:04:20.279> do 01:04:20.510 --> 01:04:20.520 align:start position:0% I think that might be a better way to do 01:04:20.520 --> 01:04:23.230 align:start position:0% I think that might be a better way to do this<01:04:20.760> but<01:04:21.319> we'll<01:04:21.559> do<01:04:21.680> it<01:04:21.880> like<01:04:22.079> this<01:04:22.279> today<01:04:22.960> we 01:04:23.230 --> 01:04:23.240 align:start position:0% this but we'll do it like this today we 01:04:23.240 --> 01:04:25.950 align:start position:0% this but we'll do it like this today we just<01:04:23.400> need<01:04:23.599> to<01:04:23.760> redefine<01:04:24.480> our<01:04:24.839> interface<01:04:25.440> here 01:04:25.950 --> 01:04:25.960 align:start position:0% just need to redefine our interface here 01:04:25.960 --> 01:04:28.390 align:start position:0% just need to redefine our interface here so<01:04:26.119> we<01:04:26.240> say<01:04:26.520> this<01:04:26.599> is<01:04:26.720> our<01:04:27.000> contract<01:04:27.760> compute 01:04:28.390 --> 01:04:28.400 align:start position:0% so we say this is our contract compute 01:04:28.400 --> 01:04:30.829 align:start position:0% so we say this is our contract compute and<01:04:28.559> then<01:04:28.680> we<01:04:28.839> just<01:04:29.000> like<01:04:29.200> copy<01:04:29.520> paste<01:04:30.160> what<01:04:30.319> we 01:04:30.829 --> 01:04:30.839 align:start position:0% and then we just like copy paste what we 01:04:30.839 --> 01:04:35.510 align:start position:0% and then we just like copy paste what we defined<01:04:31.839> uh<01:04:32.799> here<01:04:33.799> we<01:04:33.960> just<01:04:34.119> need<01:04:34.359> to<01:04:34.960> put<01:04:35.160> it 01:04:35.510 --> 01:04:35.520 align:start position:0% defined uh here we just need to put it 01:04:35.520 --> 01:04:37.510 align:start position:0% defined uh here we just need to put it again<01:04:35.839> here<01:04:36.079> in<01:04:36.200> an<01:04:36.440> interface<01:04:37.240> I<01:04:37.319> think 01:04:37.510 --> 01:04:37.520 align:start position:0% again here in an interface I think 01:04:37.520 --> 01:04:39.789 align:start position:0% again here in an interface I think that's<01:04:37.680> a<01:04:37.839> better<01:04:38.079> way<01:04:38.240> to<01:04:38.400> do<01:04:38.599> it<01:04:38.880> but<01:04:39.400> I'm<01:04:39.599> not 01:04:39.789 --> 01:04:39.799 align:start position:0% that's a better way to do it but I'm not 01:04:39.799 --> 01:04:41.829 align:start position:0% that's a better way to do it but I'm not going<01:04:40.039> to<01:04:40.319> to<01:04:40.480> show<01:04:40.720> it<01:04:40.839> today 01:04:41.829 --> 01:04:41.839 align:start position:0% going to to show it today 01:04:41.839 --> 01:04:50.029 align:start position:0% going to to show it today because<01:04:42.839> yeah<01:04:43.200> we<01:04:44.000> might<01:04:44.200> be<01:04:44.319> running<01:04:44.680> out<01:04:44.839> of 01:04:50.029 --> 01:04:50.039 align:start position:0% 01:04:50.039 --> 01:04:52.950 align:start position:0% time<01:04:51.039> so<01:04:51.599> yeah<01:04:51.799> this<01:04:51.920> is<01:04:52.599> quite 01:04:52.950 --> 01:04:52.960 align:start position:0% time so yeah this is quite 01:04:52.960 --> 01:04:55.190 align:start position:0% time so yeah this is quite straightforward<01:04:53.680> you<01:04:53.839> make<01:04:54.079> like<01:04:54.279> a<01:04:54.760> a<01:04:54.920> new 01:04:55.190 --> 01:04:55.200 align:start position:0% straightforward you make like a a new 01:04:55.200 --> 01:04:58.190 align:start position:0% straightforward you make like a a new test<01:04:56.079> file<01:04:56.799> then<01:04:56.920> you<01:04:57.119> just<01:04:57.319> have<01:04:57.480> to<01:04:57.680> put<01:04:57.960> like 01:04:58.190 --> 01:04:58.200 align:start position:0% test file then you just have to put like 01:04:58.200 --> 01:05:01.750 align:start position:0% test file then you just have to put like compute<01:04:58.680> test<01:04:59.359> is<01:04:59.680> test<01:05:00.240> whatever<01:05:01.240> uh<01:05:01.520> just 01:05:01.750 --> 01:05:01.760 align:start position:0% compute test is test whatever uh just 01:05:01.760 --> 01:05:06.390 align:start position:0% compute test is test whatever uh just like<01:05:02.119> a<01:05:03.240> um<01:05:04.240> storage<01:05:04.760> value<01:05:05.079> for<01:05:05.400> your<01:05:06.119> your 01:05:06.390 --> 01:05:06.400 align:start position:0% like a um storage value for your your 01:05:06.400 --> 01:05:08.910 align:start position:0% like a um storage value for your your contract<01:05:07.039> and<01:05:07.200> then<01:05:08.160> what<01:05:08.319> is<01:05:08.480> going<01:05:08.680> to 01:05:08.910 --> 01:05:08.920 align:start position:0% contract and then what is going to 01:05:08.920 --> 01:05:11.349 align:start position:0% contract and then what is going to happen<01:05:09.240> is<01:05:09.440> that<01:05:10.119> uh<01:05:10.279> you<01:05:10.440> just<01:05:10.640> have<01:05:10.799> to<01:05:11.039> cast 01:05:11.349 --> 01:05:11.359 align:start position:0% happen is that uh you just have to cast 01:05:11.359 --> 01:05:14.670 align:start position:0% happen is that uh you just have to cast it<01:05:12.039> so<01:05:12.240> we<01:05:12.440> Define<01:05:12.799> the<01:05:12.920> interface<01:05:13.520> here<01:05:14.520> so 01:05:14.670 --> 01:05:14.680 align:start position:0% it so we Define the interface here so 01:05:14.680 --> 01:05:17.190 align:start position:0% it so we Define the interface here so you<01:05:14.839> just<01:05:15.119> cast<01:05:15.440> it<01:05:16.279> or<01:05:16.480> you<01:05:16.559> can<01:05:16.799> keep<01:05:17.039> the 01:05:17.190 --> 01:05:17.200 align:start position:0% you just cast it or you can keep the 01:05:17.200 --> 01:05:20.029 align:start position:0% you just cast it or you can keep the address<01:05:17.599> as<01:05:17.720> you<01:05:18.319> want<01:05:19.319> and<01:05:19.440> then<01:05:19.599> you<01:05:19.799> just 01:05:20.029 --> 01:05:20.039 align:start position:0% address as you want and then you just 01:05:20.039 --> 01:05:22.990 align:start position:0% address as you want and then you just going<01:05:20.240> to<01:05:20.400> use<01:05:20.599> the<01:05:20.920> have<01:05:21.680> deployer<01:05:22.680> and<01:05:22.839> you 01:05:22.990 --> 01:05:23.000 align:start position:0% going to use the have deployer and you 01:05:23.000 --> 01:05:25.870 align:start position:0% going to use the have deployer and you do<01:05:23.240> like<01:05:23.480> that<01:05:24.319> sorry<01:05:24.640> you<01:05:24.799> do<01:05:25.000> like<01:05:25.240> that 01:05:25.870 --> 01:05:25.880 align:start position:0% do like that sorry you do like that 01:05:25.880 --> 01:05:27.829 align:start position:0% do like that sorry you do like that deploy<01:05:26.720> and<01:05:26.839> you<01:05:27.000> put<01:05:27.160> the<01:05:27.319> name<01:05:27.520> of<01:05:27.640> your 01:05:27.829 --> 01:05:27.839 align:start position:0% deploy and you put the name of your 01:05:27.839 --> 01:05:29.870 align:start position:0% deploy and you put the name of your contract<01:05:28.760> I<01:05:28.880> think<01:05:29.160> the<01:05:29.319> name<01:05:29.520> of<01:05:29.680> the 01:05:29.870 --> 01:05:29.880 align:start position:0% contract I think the name of the 01:05:29.880 --> 01:05:32.150 align:start position:0% contract I think the name of the contract<01:05:30.839> the<01:05:31.039> contract<01:05:31.480> is<01:05:31.680> actually<01:05:32.000> the 01:05:32.150 --> 01:05:32.160 align:start position:0% contract the contract is actually the 01:05:32.160 --> 01:05:33.309 align:start position:0% contract the contract is actually the name<01:05:32.319> of<01:05:32.480> the 01:05:33.309 --> 01:05:33.319 align:start position:0% name of the 01:05:33.319 --> 01:05:37.910 align:start position:0% name of the file<01:05:34.359> um<01:05:35.359> yeah<01:05:36.119> so<01:05:36.839> if<01:05:36.960> you<01:05:37.079> do<01:05:37.319> this<01:05:37.720> the 01:05:37.910 --> 01:05:37.920 align:start position:0% file um yeah so if you do this the 01:05:37.920 --> 01:05:39.630 align:start position:0% file um yeah so if you do this the contract<01:05:38.359> will<01:05:38.480> be<01:05:38.640> deployed<01:05:39.359> and<01:05:39.440> then<01:05:39.559> you 01:05:39.630 --> 01:05:39.640 align:start position:0% contract will be deployed and then you 01:05:39.640 --> 01:05:42.670 align:start position:0% contract will be deployed and then you can<01:05:39.799> write<01:05:40.039> your<01:05:40.319> F<01:05:40.960> first<01:05:41.319> test<01:05:42.079> so<01:05:42.359> in<01:05:42.480> this 01:05:42.670 --> 01:05:42.680 align:start position:0% can write your F first test so in this 01:05:42.680 --> 01:05:45.630 align:start position:0% can write your F first test so in this case<01:05:42.880> we're<01:05:43.119> just<01:05:43.359> like<01:05:44.000> expecting<01:05:45.000> uh<01:05:45.200> random 01:05:45.630 --> 01:05:45.640 align:start position:0% case we're just like expecting uh random 01:05:45.640 --> 01:05:48.789 align:start position:0% case we're just like expecting uh random values<01:05:46.000> that<01:05:46.119> would<01:05:46.319> be<01:05:46.920> fuzzed<01:05:47.920> and<01:05:48.559> yeah<01:05:48.680> we 01:05:48.789 --> 01:05:48.799 align:start position:0% values that would be fuzzed and yeah we 01:05:48.799 --> 01:05:52.269 align:start position:0% values that would be fuzzed and yeah we say<01:05:49.119> Okay<01:05:49.359> so<01:05:50.359> the<01:05:50.520> contract<01:05:50.920> should<01:05:51.279> return<01:05:51.559> C 01:05:52.269 --> 01:05:52.279 align:start position:0% say Okay so the contract should return C 01:05:52.279 --> 01:05:55.190 align:start position:0% say Okay so the contract should return C and<01:05:52.440> we<01:05:52.880> we<01:05:53.000> can<01:05:53.200> just<01:05:53.400> check<01:05:53.760> that<01:05:54.160> c<01:05:54.599> is<01:05:55.000> the 01:05:55.190 --> 01:05:55.200 align:start position:0% and we we can just check that c is the 01:05:55.200 --> 01:06:03.789 align:start position:0% and we we can just check that c is the sum<01:05:55.480> of<01:05:55.680> of<01:05:56.000> A<01:05:56.760> and 01:06:03.789 --> 01:06:03.799 align:start position:0% 01:06:03.799 --> 01:06:16.230 align:start position:0% B<01:06:04.799> I'll<01:06:05.000> give<01:06:05.160> you<01:06:05.279> a<01:06:05.359> few 01:06:16.230 --> 01:06:16.240 align:start position:0% 01:06:16.240 --> 01:06:19.990 align:start position:0% seconds<01:06:17.240> do<01:06:17.359> you<01:06:17.520> have<01:06:17.680> any<01:06:17.960> questions<01:06:19.000> or 01:06:19.990 --> 01:06:20.000 align:start position:0% seconds do you have any questions or 01:06:20.000 --> 01:06:21.990 align:start position:0% seconds do you have any questions or anything<01:06:20.559> like<01:06:20.839> that<01:06:21.000> you're<01:06:21.319> struggling 01:06:21.990 --> 01:06:22.000 align:start position:0% anything like that you're struggling 01:06:22.000 --> 01:06:25.150 align:start position:0% anything like that you're struggling with<01:06:22.319> like<01:06:22.799> I<01:06:22.960> I<01:06:23.039> know<01:06:23.279> this<01:06:23.400> is<01:06:23.720> a<01:06:23.920> lot<01:06:24.119> of<01:06:25.039> a 01:06:25.150 --> 01:06:25.160 align:start position:0% with like I I know this is a lot of a 01:06:25.160 --> 01:06:28.230 align:start position:0% with like I I know this is a lot of a lot<01:06:25.279> of<01:06:25.640> things<01:06:26.160> all<01:06:26.400> at<01:06:26.640> once<01:06:27.640> uh<01:06:27.799> it<01:06:27.920> can<01:06:28.039> be<01:06:28.160> a 01:06:28.230 --> 01:06:28.240 align:start position:0% lot of things all at once uh it can be a 01:06:28.240 --> 01:06:30.269 align:start position:0% lot of things all at once uh it can be a bit<01:06:28.400> tedious<01:06:28.839> to<01:06:29.000> set<01:06:29.200> up<01:06:29.480> everything<01:06:29.880> so<01:06:30.119> if 01:06:30.269 --> 01:06:30.279 align:start position:0% bit tedious to set up everything so if 01:06:30.279 --> 01:06:32.630 align:start position:0% bit tedious to set up everything so if something<01:06:30.599> is<01:06:30.720> not<01:06:31.079> working<01:06:32.079> uh<01:06:32.240> we<01:06:32.359> still 01:06:32.630 --> 01:06:32.640 align:start position:0% something is not working uh we still 01:06:32.640 --> 01:06:35.390 align:start position:0% something is not working uh we still have<01:06:32.880> like<01:06:33.160> a<01:06:33.799> less<01:06:34.039> than<01:06:34.319> one<01:06:34.559> hour<01:06:35.000> but<01:06:35.279> we 01:06:35.390 --> 01:06:35.400 align:start position:0% have like a less than one hour but we 01:06:35.400 --> 01:06:36.910 align:start position:0% have like a less than one hour but we can<01:06:35.680> take<01:06:35.880> some<01:06:36.119> time 01:06:36.910 --> 01:06:36.920 align:start position:0% can take some time 01:06:36.920 --> 01:06:49.829 align:start position:0% can take some time to<01:06:37.920> to<01:06:38.160> fix<01:06:38.440> some 01:06:49.829 --> 01:06:49.839 align:start position:0% 01:06:49.839 --> 01:06:52.150 align:start position:0% issues<01:06:50.839> can<01:06:50.960> you<01:06:51.119> just<01:06:51.359> explain<01:06:51.680>

our<01:07:13.599> I'll<01:07:13.760> go<01:07:13.920> back<01:07:14.039> to<01:07:14.160> the 01:07:14.269 --> 01:07:14.279 align:start position:0% we go here in our I'll go back to the 01:07:14.279 --> 01:07:16.109 align:start position:0% we go here in our I'll go back to the next<01:07:14.440> slide<01:07:14.720> I'm<01:07:14.839> sorry<01:07:15.160> for<01:07:15.400> those<01:07:15.599> who<01:07:15.640> are 01:07:16.109 --> 01:07:16.119 align:start position:0% next slide I'm sorry for those who are 01:07:16.119 --> 01:07:18.309 align:start position:0% next slide I'm sorry for those who are copying<01:07:16.520> the<01:07:16.680> code<01:07:17.200> but<01:07:17.319> if<01:07:17.440> you<01:07:17.559> go<01:07:17.799> here<01:07:18.079> like 01:07:18.309 --> 01:07:18.319 align:start position:0% copying the code but if you go here like 01:07:18.319 --> 01:07:23.470 align:start position:0% copying the code but if you go here like add<01:07:19.000> we<01:07:19.559> have<01:07:20.200> no<01:07:20.760> uh<01:07:20.920> overflow<01:07:21.520> check<01:07:22.279> so<01:07:23.240> if 01:07:23.470 --> 01:07:23.480 align:start position:0% add we have no uh overflow check so if 01:07:23.480 --> 01:07:26.069 align:start position:0% add we have no uh overflow check so if we<01:07:23.839> are<01:07:24.200> just<01:07:24.559> doing<01:07:24.920> like<01:07:25.160> a 01:07:26.069 --> 01:07:26.079 align:start position:0% we are just doing like a 01:07:26.079 --> 01:07:29.549 align:start position:0% we are just doing like a assert<01:07:26.640> like<01:07:26.880> the<01:07:27.279> sum<01:07:27.760> here<01:07:28.039> and<01:07:28.319> we<01:07:28.720> have<01:07:29.359> we 01:07:29.549 --> 01:07:29.559 align:start position:0% assert like the sum here and we have we 01:07:29.559 --> 01:07:31.950 align:start position:0% assert like the sum here and we have we don't<01:07:29.799> have<01:07:30.000> unchecked<01:07:30.920> then<01:07:31.160> solidity<01:07:31.760> will 01:07:31.950 --> 01:07:31.960 align:start position:0% don't have unchecked then solidity will 01:07:31.960 --> 01:07:34.150 align:start position:0% don't have unchecked then solidity will do<01:07:32.160> like<01:07:32.400> a<01:07:32.599> overflow<01:07:33.160> check<01:07:33.760> and<01:07:33.880> then<01:07:34.039> the 01:07:34.150 --> 01:07:34.160 align:start position:0% do like a overflow check and then the 01:07:34.160 --> 01:07:36.870 align:start position:0% do like a overflow check and then the code<01:07:34.480> will<01:07:34.960> revert<01:07:35.880> or<01:07:36.160> we<01:07:36.279> won't<01:07:36.559> have<01:07:36.720> the 01:07:36.870 --> 01:07:36.880 align:start position:0% code will revert or we won't have the 01:07:36.880 --> 01:07:40.630 align:start position:0% code will revert or we won't have the same<01:07:37.079> result<01:07:37.920> as<01:07:38.160> our<01:07:38.599> have<01:07:39.039> code<01:07:40.039> uh<01:07:40.200> but<01:07:40.440> yeah 01:07:40.630 --> 01:07:40.640 align:start position:0% same result as our have code uh but yeah 01:07:40.640 --> 01:07:42.069 align:start position:0% same result as our have code uh but yeah that<01:07:40.839> that's<01:07:40.960> an<01:07:41.160> interesting<01:07:41.680> question 01:07:42.069 --> 01:07:42.079 align:start position:0% that that's an interesting question 01:07:42.079 --> 01:07:45.789 align:start position:0% that that's an interesting question because<01:07:42.760> here<01:07:42.920> in<01:07:43.119> solidity<01:07:43.960> now<01:07:44.559> we<01:07:44.760> have<01:07:45.079> the 01:07:45.789 --> 01:07:45.799 align:start position:0% because here in solidity now we have the 01:07:45.799 --> 01:07:47.910 align:start position:0% because here in solidity now we have the Overflow<01:07:46.400> check<01:07:46.760> but<01:07:46.880> we<01:07:47.000> don't<01:07:47.279> have<01:07:47.400> it<01:07:47.640> in 01:07:47.910 --> 01:07:47.920 align:start position:0% Overflow check but we don't have it in 01:07:47.920 --> 01:07:50.750 align:start position:0% Overflow check but we don't have it in in<01:07:48.200> half<01:07:48.720> so<01:07:49.039> maybe<01:07:49.520> like<01:07:50.000> something<01:07:50.400> that<01:07:50.559> you 01:07:50.750 --> 01:07:50.760 align:start position:0% in half so maybe like something that you 01:07:50.760 --> 01:07:55.029 align:start position:0% in half so maybe like something that you guys<01:07:50.960> can<01:07:51.520> do<01:07:52.200> is<01:07:52.480> a<01:07:52.680> way<01:07:52.880> to<01:07:53.880> prevent<01:07:54.440> the<01:07:54.760> half 01:07:55.029 --> 01:07:55.039 align:start position:0% guys can do is a way to prevent the half 01:07:55.039 --> 01:07:58.150 align:start position:0% guys can do is a way to prevent the half contract<01:07:55.880> from<01:07:56.880> uh<01:07:57.119> the<01:07:57.279> sum<01:07:57.599> from 01:07:58.150 --> 01:07:58.160 align:start position:0% contract from uh the sum from 01:07:58.160 --> 01:07:59.910 align:start position:0% contract from uh the sum from overflowing<01:07:59.119> so<01:07:59.319> that<01:07:59.440> could<01:07:59.599> be<01:07:59.760> an 01:07:59.910 --> 01:07:59.920 align:start position:0% overflowing so that could be an 01:07:59.920 --> 01:08:02.309 align:start position:0% overflowing so that could be an interesting<01:08:00.520> exercise<01:08:01.400> I<01:08:01.480> think<01:08:01.760> there's 01:08:02.309 --> 01:08:02.319 align:start position:0% interesting exercise I think there's 01:08:02.319 --> 01:08:04.990 align:start position:0% interesting exercise I think there's already<01:08:02.640> a<01:08:02.839> li<01:08:03.559> like<01:08:03.799> like<01:08:03.960> a<01:08:04.119> small<01:08:04.520> library 01:08:04.990 --> 01:08:05.000 align:start position:0% already a li like like a small library 01:08:05.000 --> 01:08:07.630 align:start position:0% already a li like like a small library in<01:08:05.279> half<01:08:05.599> mate<01:08:06.359> that<01:08:06.640> can<01:08:06.839> allows<01:08:07.160> you<01:08:07.279> to<01:08:07.440> do 01:08:07.630 --> 01:08:07.640 align:start position:0% in half mate that can allows you to do 01:08:07.640 --> 01:08:11.269 align:start position:0% in half mate that can allows you to do this<01:08:07.880> but<01:08:08.400> it<01:08:08.520> could<01:08:08.640> be<01:08:08.880> quite<01:08:09.240> simple<01:08:10.000> to<01:08:11.000> to 01:08:11.269 --> 01:08:11.279 align:start position:0% this but it could be quite simple to to 01:08:11.279 --> 01:08:18.749 align:start position:0% this but it could be quite simple to to code 01:08:18.749 --> 01:08:18.759 align:start position:0% 01:08:18.759 --> 01:08:22.030 align:start position:0% actually<01:08:19.759> hey<01:08:19.920> sorry<01:08:20.239> one<01:08:20.359> more<01:08:20.600> question<01:08:21.440> um 01:08:22.030 --> 01:08:22.040 align:start position:0% actually hey sorry one more question um 01:08:22.040 --> 01:08:25.149 align:start position:0% actually hey sorry one more question um you<01:08:22.199> mentioned<01:08:22.640> that<01:08:23.239> over<01:08:23.480> here<01:08:24.040> um<01:08:24.799> bit<01:08:24.960> off 01:08:25.149 --> 01:08:25.159 align:start position:0% you mentioned that over here um bit off 01:08:25.159 --> 01:08:27.630 align:start position:0% you mentioned that over here um bit off topic<01:08:25.600> you<01:08:25.719> mentioned<01:08:26.199> that<01:08:26.759> uh<01:08:27.000> advantage<01:08:27.440> of 01:08:27.630 --> 01:08:27.640 align:start position:0% topic you mentioned that uh advantage of 01:08:27.640 --> 01:08:30.149 align:start position:0% topic you mentioned that uh advantage of using<01:08:27.960> Huff<01:08:28.400> is<01:08:28.920> you<01:08:29.159> have<01:08:29.440> complete<01:08:29.920> access 01:08:30.149 --> 01:08:30.159 align:start position:0% using Huff is you have complete access 01:08:30.159 --> 01:08:33.709 align:start position:0% using Huff is you have complete access to<01:08:30.520> all<01:08:30.679> the<01:08:30.799> op<01:08:31.040>

--> 01:08:35.709 align:start position:0% to all the op codes um what is one use case<01:08:33.920> that<01:08:34.000> you've<01:08:34.239> found<01:08:35.120> where<01:08:35.319> you<01:08:35.400> can 01:08:35.709 --> 01:08:35.719 align:start position:0% case that you've found where you can 01:08:35.719 --> 01:08:37.269 align:start position:0% case that you've found where you can particularly<01:08:36.199> exploit<01:08:36.600> that<01:08:36.719> to<01:08:36.920> achieve 01:08:37.269 --> 01:08:37.279 align:start position:0% particularly exploit that to achieve 01:08:37.279 --> 01:08:38.430 align:start position:0% particularly exploit that to achieve something<01:08:37.600> that<01:08:37.679> you<01:08:37.799> haven't<01:08:38.000> been<01:08:38.159> able<01:08:38.319> to 01:08:38.430 --> 01:08:38.440 align:start position:0% something that you haven't been able to 01:08:38.440 --> 01:08:40.070 align:start position:0% something that you haven't been able to do<01:08:38.920> in<01:08:39.080> another 01:08:40.070 --> 01:08:40.080 align:start position:0% do in another 01:08:40.080 --> 01:08:43.910 align:start position:0% do in another language<01:08:41.080> uh<01:08:41.799> it's<01:08:42.199> so<01:08:42.679> personally<01:08:43.440> I<01:08:43.600> haven't 01:08:43.910 --> 01:08:43.920 align:start position:0% language uh it's so personally I haven't 01:08:43.920 --> 01:08:46.630 align:start position:0% language uh it's so personally I haven't been<01:08:44.239> like<01:08:44.440> doing<01:08:45.239> I<01:08:45.359> haven't<01:08:45.600> been<01:08:45.839> coding 01:08:46.630 --> 01:08:46.640 align:start position:0% been like doing I haven't been coding 01:08:46.640 --> 01:08:50.309 align:start position:0% been like doing I haven't been coding for<01:08:47.120> production<01:08:47.839> things<01:08:48.839> uh<01:08:49.159> I<01:08:49.239> was<01:08:49.560> more<01:08:50.080> as<01:08:50.199> I 01:08:50.309 --> 01:08:50.319 align:start position:0% for production things uh I was more as I 01:08:50.319 --> 01:08:52.110 align:start position:0% for production things uh I was more as I said<01:08:50.679> like<01:08:51.040> in<01:08:51.159> the 01:08:52.110 --> 01:08:52.120 align:start position:0% said like in the 01:08:52.120 --> 01:08:54.870 align:start position:0% said like in the beginning<01:08:53.120> I<01:08:53.279> really<01:08:53.480> wanted<01:08:53.799> to<01:08:54.000> learn<01:08:54.359> how 01:08:54.870 --> 01:08:54.880 align:start position:0% beginning I really wanted to learn how 01:08:54.880 --> 01:08:57.390 align:start position:0% beginning I really wanted to learn how the<01:08:55.000> evm<01:08:55.560> was<01:08:55.719> working<01:08:56.520> and<01:08:56.719> actually<01:08:57.159> just 01:08:57.390 --> 01:08:57.400 align:start position:0% the evm was working and actually just 01:08:57.400 --> 01:08:59.590 align:start position:0% the evm was working and actually just like<01:08:57.560> writing<01:08:57.920> some<01:08:58.279> have<01:08:58.799> was<01:08:59.000> like<01:08:59.199> the<01:08:59.359> best 01:08:59.590 --> 01:08:59.600 align:start position:0% like writing some have was like the best 01:08:59.600 --> 01:09:01.430 align:start position:0% like writing some have was like the best way<01:08:59.799> because<01:09:00.040> writing<01:09:00.440> resources<01:09:01.040> is<01:09:01.159> a<01:09:01.279> bit 01:09:01.430 --> 01:09:01.440 align:start position:0% way because writing resources is a bit 01:09:01.440 --> 01:09:03.550 align:start position:0% way because writing resources is a bit tedious<01:09:02.359> but<01:09:02.600> otherwise<01:09:03.040> like<01:09:03.159> I've<01:09:03.319> seen 01:09:03.550 --> 01:09:03.560 align:start position:0% tedious but otherwise like I've seen 01:09:03.560 --> 01:09:07.789 align:start position:0% tedious but otherwise like I've seen many<01:09:03.839> people<01:09:04.159> doing<01:09:04.600> like<01:09:05.239> um<01:09:06.239> uh<01:09:06.480> yeah<01:09:06.920> um<01:09:07.279> me 01:09:07.789 --> 01:09:07.799 align:start position:0% many people doing like um uh yeah um me 01:09:07.799 --> 01:09:10.550 align:start position:0% many people doing like um uh yeah um me boats<01:09:08.520> boats<01:09:08.960> or<01:09:09.279> things<01:09:09.600> like<01:09:09.799> that<01:09:10.279> they're 01:09:10.550 --> 01:09:10.560 align:start position:0% boats boats or things like that they're 01:09:10.560 --> 01:09:14.110 align:start position:0% boats boats or things like that they're using<01:09:11.040> half<01:09:11.920> and<01:09:12.480> yeah<01:09:12.640> I<01:09:12.719> mean<01:09:12.920> like<01:09:13.400> you<01:09:13.600> have 01:09:14.110 --> 01:09:14.120 align:start position:0% using half and yeah I mean like you have 01:09:14.120 --> 01:09:17.110 align:start position:0% using half and yeah I mean like you have more<01:09:15.120> you<01:09:15.239> have<01:09:15.480> access<01:09:15.759> to<01:09:15.960> many<01:09:16.279> things<01:09:16.839> and 01:09:17.110 --> 01:09:17.120 align:start position:0% more you have access to many things and 01:09:17.120 --> 01:09:18.950 align:start position:0% more you have access to many things and what<01:09:17.279> what<01:09:17.359> is<01:09:17.560> interesting<01:09:18.120> also<01:09:18.440> is<01:09:18.640> that 01:09:18.950 --> 01:09:18.960 align:start position:0% what what is interesting also is that 01:09:18.960 --> 01:09:20.870 align:start position:0% what what is interesting also is that you're<01:09:19.199> not<01:09:19.440> writing<01:09:19.839> solidity<01:09:20.480> code<01:09:20.719> you're 01:09:20.870 --> 01:09:20.880 align:start position:0% you're not writing solidity code you're 01:09:20.880 --> 01:09:24.229 align:start position:0% you're not writing solidity code you're not<01:09:21.000> writing<01:09:21.440> like<01:09:21.839> uh<01:09:22.199> or<01:09:22.359> even<01:09:22.679> Viper<01:09:23.679> um<01:09:23.960> so 01:09:24.229 --> 01:09:24.239 align:start position:0% not writing like uh or even Viper um so 01:09:24.239 --> 01:09:27.510 align:start position:0% not writing like uh or even Viper um so you<01:09:24.359> can<01:09:24.560> do<01:09:24.799> like<01:09:25.000> a<01:09:25.440> as<01:09:25.600> we<01:09:26.440> we<01:09:26.560> saw<01:09:27.000> earlier 01:09:27.510 --> 01:09:27.520 align:start position:0% you can do like a as we we saw earlier 01:09:27.520 --> 01:09:29.749 align:start position:0% you can do like a as we we saw earlier like<01:09:27.679> the<01:09:27.799> function<01:09:28.199> dispatching<01:09:29.159> if<01:09:29.319> you<01:09:29.440> are 01:09:29.749 --> 01:09:29.759 align:start position:0% like the function dispatching if you are 01:09:29.759 --> 01:09:31.829 align:start position:0% like the function dispatching if you are just<01:09:30.080> writing<01:09:30.440> your<01:09:30.600> own<01:09:30.839> butt<01:09:31.159> for<01:09:31.400> your<01:09:31.560> own 01:09:31.829 --> 01:09:31.839 align:start position:0% just writing your own butt for your own 01:09:31.839 --> 01:09:33.789 align:start position:0% just writing your own butt for your own purpose<01:09:32.279> you<01:09:32.359> don't<01:09:32.600> care<01:09:32.799> about<01:09:33.040> that<01:09:33.480> so<01:09:33.679> you 01:09:33.789 --> 01:09:33.799 align:start position:0% purpose you don't care about that so you 01:09:33.799 --> 01:09:36.590 align:start position:0% purpose you don't care about that so you can<01:09:34.199> remove<01:09:34.679> like<01:09:35.040> uh<01:09:35.440> a<01:09:35.560> lot<01:09:35.759> of<01:09:35.880> the<01:09:36.040> safety 01:09:36.590 --> 01:09:36.600 align:start position:0% can remove like uh a lot of the safety 01:09:36.600 --> 01:09:39.390 align:start position:0% can remove like uh a lot of the safety features<01:09:37.199> from<01:09:37.799> solidity<01:09:38.600> because<01:09:39.159> if<01:09:39.279> you 01:09:39.390 --> 01:09:39.400 align:start position:0% features from solidity because if you 01:09:39.400 --> 01:09:42.030 align:start position:0% features from solidity because if you know<01:09:39.679> exactly<01:09:40.640> what<01:09:40.799> you<01:09:40.920> want<01:09:41.120> to<01:09:41.279> do<01:09:41.600> you<01:09:41.759> can 01:09:42.030 --> 01:09:42.040 align:start position:0% know exactly what you want to do you can 01:09:42.040 --> 01:09:46.990 align:start position:0% know exactly what you want to do you can achieve<01:09:42.319> it<01:09:42.600> this<01:09:43.120> way<01:09:44.120> but<01:09:45.239> uh<01:09:46.239> yeah<01:09:46.440> like 01:09:46.990 --> 01:09:47.000 align:start position:0% achieve it this way but uh yeah like 01:09:47.000 --> 01:09:51.749 align:start position:0% achieve it this way but uh yeah like some<01:09:48.000> some<01:09:48.400> stuff<01:09:48.839> also<01:09:49.199> in<01:09:49.839> uh<01:09:50.839> like<01:09:51.480> main 01:09:51.749 --> 01:09:51.759 align:start position:0% some some stuff also in uh like main 01:09:51.759 --> 01:09:53.430 align:start position:0% some some stuff also in uh like main difference<01:09:52.199> is<01:09:52.400> also<01:09:52.640> you<01:09:52.799> have<01:09:53.000> access<01:09:53.279> to 01:09:53.430 --> 01:09:53.440 align:start position:0% difference is also you have access to 01:09:53.440 --> 01:09:55.709 align:start position:0% difference is also you have access to more<01:09:53.679> up<01:09:53.920> codes<01:09:54.199> I<01:09:54.320> don't<01:09:54.520> have<01:09:54.719> like<01:09:54.840> an<01:09:55.040> examp 01:09:55.709 --> 01:09:55.719 align:start position:0% more up codes I don't have like an examp 01:09:55.719 --> 01:09:59.550 align:start position:0% more up codes I don't have like an examp example<01:09:56.320> here<01:09:56.960> but<01:09:57.159> I<01:09:57.239> would<01:09:57.480> say<01:09:58.159> yeah<01:09:58.560> like 01:09:59.550 --> 01:09:59.560 align:start position:0% example here but I would say yeah like 01:09:59.560 --> 01:10:02.870 align:start position:0% example here but I would say yeah like there<01:09:59.679> are<01:09:59.960> so<01:10:00.520> many<01:10:01.520> other<01:10:01.840> cases<01:10:02.280> but<01:10:02.520> for 01:10:02.870 --> 01:10:02.880 align:start position:0% there are so many other cases but for 01:10:02.880 --> 01:10:05.350 align:start position:0% there are so many other cases but for this<01:10:03.199> one<01:10:03.719> specifically<01:10:04.719> I'm<01:10:04.800> sure<01:10:05.040> we<01:10:05.159> can 01:10:05.350 --> 01:10:05.360 align:start position:0% this one specifically I'm sure we can 01:10:05.360 --> 01:10:12.910 align:start position:0% this one specifically I'm sure we can find<01:10:05.560> it<01:10:05.760> but<01:10:05.880> I<01:10:06.000> don't<01:10:06.239> have<01:10:06.400> it<01:10:06.880> in 01:10:12.910 --> 01:10:12.920 align:start position:0% 01:10:12.920 --> 01:10:21.470 align:start position:0% mind 01:10:21.470 --> 01:10:21.480 align:start position:0% 01:10:21.480 --> 01:10:23.590 align:start position:0% yeah 01:10:23.590 --> 01:10:23.600 align:start position:0% yeah 01:10:23.600 --> 01:10:29.950 align:start position:0% yeah yeah<01:10:24.600> yeah<01:10:25.360> could<01:10:25.520> be<01:10:25.679> a<01:10:26.080> example 01:10:29.950 --> 01:10:29.960 align:start position:0% 01:10:29.960 --> 01:10:31.669 align:start position:0% yeah<01:10:30.960> all 01:10:31.669 --> 01:10:31.679 align:start position:0% yeah all 01:10:31.679 --> 01:10:41.070 align:start position:0% yeah all right<01:10:33.120> so<01:10:34.440> yep<01:10:35.440> okay<01:10:35.640> let<01:10:35.800> me 01:10:41.070 --> 01:10:41.080 align:start position:0% 01:10:41.080 --> 01:10:45.630 align:start position:0% see<01:10:42.080> oh<01:10:42.239> you<01:10:42.400> put<01:10:42.640> like<01:10:42.880> a<01:10:43.520> uh<01:10:43.760> you<01:10:43.960> went<01:10:44.640> eight 01:10:45.630 --> 01:10:45.640 align:start position:0% see oh you put like a uh you went eight 01:10:45.640 --> 01:10:47.790 align:start position:0% see oh you put like a uh you went eight yeah<01:10:46.000> just<01:10:46.239> put<01:10:46.480> like<01:10:46.800> a 01:10:47.790 --> 01:10:47.800 align:start position:0% yeah just put like a 01:10:47.800 --> 01:10:51.630 align:start position:0% yeah just put like a 256 01:10:51.630 --> 01:10:51.640 align:start position:0% 01:10:51.640 --> 01:10:53.590 align:start position:0% yeah 01:10:53.590 --> 01:10:53.600 align:start position:0% yeah 01:10:53.600 --> 01:10:56.630 align:start position:0% yeah yes<01:10:54.600> yeah<01:10:54.920> I<01:10:55.040> think<01:10:55.400> think<01:10:55.960> yeah<01:10:56.120> if<01:10:56.239> you<01:10:56.440> have 01:10:56.630 --> 01:10:56.640 align:start position:0% yes yeah I think think yeah if you have 01:10:56.640 --> 01:10:59.550 align:start position:0% yes yeah I think think yeah if you have like<01:10:56.960> compilation<01:10:57.880> failed<01:10:58.880> I<01:10:59.000> think<01:10:59.239> there<01:10:59.360> is 01:10:59.550 --> 01:10:59.560 align:start position:0% like compilation failed I think there is 01:10:59.560 --> 01:11:03.470 align:start position:0% like compilation failed I think there is one<01:10:59.960> step<01:11:00.960> that<01:11:01.280> we<01:11:01.520> haven't<01:11:01.960> been<01:11:02.239> doing<01:11:02.719> yet 01:11:03.470 --> 01:11:03.480 align:start position:0% one step that we haven't been doing yet 01:11:03.480 --> 01:11:05.750 align:start position:0% one step that we haven't been doing yet and<01:11:03.640> it's<01:11:03.960> just 01:11:05.750 --> 01:11:05.760 align:start position:0% and it's just 01:11:05.760 --> 01:11:09.070 align:start position:0% and it's just installing<01:11:06.760> uh<01:11:06.920> the<01:11:07.320> packages<01:11:08.320> so<01:11:08.760> if<01:11:08.880> you 01:11:09.070 --> 01:11:09.080 align:start position:0% installing uh the packages so if you 01:11:09.080 --> 01:11:10.950 align:start position:0% installing uh the packages so if you have<01:11:09.360> this<01:11:10.120> obviously<01:11:10.480> if<01:11:10.560> you<01:11:10.679> have<01:11:10.840> the 01:11:10.950 --> 01:11:10.960 align:start position:0% have this obviously if you have the 01:11:10.960 --> 01:11:13.070 align:start position:0% have this obviously if you have the first<01:11:11.320> contract<01:11:11.800> and<01:11:11.960> then<01:11:12.080> you<01:11:12.199> have<01:11:12.480> this 01:11:13.070 --> 01:11:13.080 align:start position:0% first contract and then you have this 01:11:13.080 --> 01:11:16.270 align:start position:0% first contract and then you have this then<01:11:13.199> you<01:11:13.320> can<01:11:13.880> try<01:11:14.880> uh<01:11:15.239> just<01:11:15.440> be<01:11:15.600> sure<01:11:15.800> to<01:11:16.040> have 01:11:16.270 --> 01:11:16.280 align:start position:0% then you can try uh just be sure to have 01:11:16.280 --> 01:11:18.510 align:start position:0% then you can try uh just be sure to have everything<01:11:16.640>

thing<01:11:41.080> like<01:11:41.760> uh<01:11:42.120> here<01:11:42.760> you<01:11:42.960> went 01:11:44.070 --> 01:11:44.080 align:start position:0% machine same thing like uh here you went 01:11:44.080 --> 01:11:47.030 align:start position:0% machine same thing like uh here you went eight<01:11:45.080> the<01:11:45.239> result<01:11:45.960> you<01:11:46.040> should<01:11:46.360> just<01:11:46.719> use 01:11:47.030 --> 01:11:47.040 align:start position:0% eight the result you should just use 01:11:47.040 --> 01:11:47.990 align:start position:0% eight the result you should just

hope it 01:11:50.840 --> 01:11:53.149 align:start position:0% 256 yeah let's see if it works I hope it will 01:11:53.149 --> 01:11:53.159 align:start position:0% 01:11:53.159 --> 01:12:11.350 align:start position:0% work<01:11:54.159> oh 01:12:11.350 --> 01:12:11.360 align:start position:0% 01:12:11.360 --> 01:12:13.510 align:start position:0% all<01:12:11.520> right<01:12:11.800> let<01:12:12.000> me<01:12:12.120> know<01:12:12.360> if<01:12:12.480> it's 01:12:13.510 --> 01:12:13.520 align:start position:0% all right let me know if it's 01:12:13.520 --> 01:12:17.189 align:start position:0% all right let me know if it's working<01:12:14.520> yeah<01:12:14.960> the<01:12:15.120> test<01:12:15.360> is<01:12:15.840> passing<01:12:16.840> hell 01:12:17.189 --> 01:12:17.199 align:start position:0% working yeah the test is passing hell 01:12:17.199 --> 01:12:21.189 align:start position:0% working yeah the test is passing hell yeah<01:12:17.679> yeah<01:12:18.639> you<01:12:18.800> have<01:12:19.000> them<01:12:19.320> the 01:12:21.189 --> 01:12:21.199 align:start position:0% yeah yeah you have them the 01:12:21.199 --> 01:12:24.750 align:start position:0% yeah yeah you have them the mic<01:12:22.199> is<01:12:22.320> there<01:12:22.480> a<01:12:22.679> way<01:12:23.000> to<01:12:23.800> uh<01:12:24.080> write<01:12:24.520> half 01:12:24.750 --> 01:12:24.760 align:start position:0% mic is there a way to uh write half 01:12:24.760 --> 01:12:28.750 align:start position:0% mic is there a way to uh write half codes<01:12:25.320> like<01:12:25.480> in<01:12:25.800> L<01:12:26.760> in<01:12:27.520> solidity<01:12:28.520> yeah 01:12:28.750 --> 01:12:28.760 align:start position:0% codes like in L in solidity yeah 01:12:28.760 --> 01:12:30.910 align:start position:0% codes like in L in solidity yeah actually<01:12:29.520> there<01:12:29.679> is<01:12:29.880> one<01:12:30.320> I<01:12:30.679> this<01:12:30.760> is 01:12:30.910 --> 01:12:30.920 align:start position:0% actually there is one I this is 01:12:30.920 --> 01:12:33.830 align:start position:0% actually there is one I this is something<01:12:31.320> I<01:12:31.440> I<01:12:31.560> showed<01:12:32.120> earlier<01:12:33.120> uh<01:12:33.679> like 01:12:33.830 --> 01:12:33.840 align:start position:0% something I I showed earlier uh like 01:12:33.840 --> 01:12:37.950 align:start position:0% something I I showed earlier uh like there<01:12:33.960> is<01:12:34.159> something<01:12:34.520> called 01:12:37.950 --> 01:12:37.960 align:start position:0% 01:12:37.960 --> 01:12:41.550 align:start position:0% idity<01:12:38.960> I<01:12:39.120> guess<01:12:39.320> it's<01:12:39.520> called<01:12:39.880> this 01:12:41.550 --> 01:12:41.560 align:start position:0% idity I guess it's called this 01:12:41.560 --> 01:12:45.189 align:start position:0% idity I guess it's called this way<01:12:42.560> but<01:12:42.760> this<01:12:42.880> is<01:12:43.199> very<01:12:43.520> very<01:12:44.199> experimental 01:12:45.189 --> 01:12:45.199 align:start position:0% way but this is very very experimental 01:12:45.199 --> 01:12:48.270 align:start position:0% way but this is very very experimental and<01:12:45.600> like<01:12:45.840> this<01:12:45.960> is<01:12:46.120> leading<01:12:46.480> to<01:12:47.120> many<01:12:48.120> uh 01:12:48.270 --> 01:12:48.280 align:start position:0% and like this is leading to many uh 01:12:48.280 --> 01:12:50.709 align:start position:0% and like this is leading to many uh where<01:12:48.440> is 01:12:50.709 --> 01:12:50.719 align:start position:0% 01:12:50.719 --> 01:12:55.510 align:start position:0% this<01:12:51.719> it's<01:12:52.560> here<01:12:53.280> yeah<01:12:53.440> so<01:12:53.760> it<01:12:54.000> works<01:12:54.880> but<01:12:55.440> I 01:12:55.510 --> 01:12:55.520 align:start position:0% this it's here yeah so it works but I 01:12:55.520 --> 01:12:57.590 align:start position:0% this it's here yeah so it works but I don't<01:12:55.719> think<01:12:56.000> this<01:12:56.120> should<01:12:56.560> ever<01:12:56.800> be<01:12:56.960> used<01:12:57.239> in 01:12:57.590 --> 01:12:57.600 align:start position:0% don't think this should ever be used in 01:12:57.600 --> 01:12:59.709 align:start position:0% don't think this should ever be used in production<01:12:58.520> because<01:12:58.800> like<01:12:58.960> the<01:12:59.080> way<01:12:59.199> it<01:12:59.320> works 01:12:59.709 --> 01:12:59.719 align:start position:0% production because like the way it works 01:12:59.719 --> 01:13:02.350 align:start position:0% production because like the way it works that<01:13:00.080> it's<01:13:00.280> just<01:13:00.719> injecting<01:13:01.719> it's<01:13:01.920> compiling 01:13:02.350 --> 01:13:02.360 align:start position:0% that it's just injecting it's compiling 01:13:02.360 --> 01:13:03.910 align:start position:0% that it's just injecting it's compiling your<01:13:02.560> code<01:13:02.880> it's 01:13:03.910 --> 01:13:03.920 align:start position:0% your code it's 01:13:03.920 --> 01:13:07.590 align:start position:0% your code it's injecting<01:13:04.920> uh<01:13:05.159> your<01:13:05.480> code<01:13:06.000> so<01:13:06.239> I<01:13:06.480> I<01:13:06.600> think<01:13:07.239> I 01:13:07.590 --> 01:13:07.600 align:start position:0% injecting uh your code so I I think I 01:13:07.600 --> 01:13:10.910 align:start position:0% injecting uh your code so I I think I mean<01:13:08.600> if<01:13:08.800> you<01:13:09.639> uh<01:13:09.800> so<01:13:10.080> if<01:13:10.159> you<01:13:10.400> really<01:13:10.600> want<01:13:10.800> to 01:13:10.910 --> 01:13:10.920 align:start position:0% mean if you uh so if you really want to 01:13:10.920 --> 01:13:14.030 align:start position:0% mean if you uh so if you really want to use<01:13:11.239> have<01:13:11.480> for<01:13:11.800> something<01:13:12.639> in<01:13:12.920> production<01:13:13.880> I 01:13:14.030 --> 01:13:14.040 align:start position:0% use have for something in production I 01:13:14.040 --> 01:13:16.990 align:start position:0% use have for something in production I guess<01:13:14.320> like<01:13:15.040> uh<01:13:15.360> something<01:13:16.360> interesting 01:13:16.990 --> 01:13:17.000 align:start position:0% guess like uh something interesting 01:13:17.000 --> 01:13:18.950 align:start position:0% guess like uh something interesting would<01:13:17.159> be<01:13:17.360> just<01:13:17.520> to<01:13:17.719> have<01:13:17.920> like 01:13:18.950 --> 01:13:18.960 align:start position:0% would be just to have like 01:13:18.960 --> 01:13:22.910 align:start position:0% would be just to have like a<01:13:19.960> deploy<01:13:20.440> maybe<01:13:20.679> a<01:13:20.840> library<01:13:21.719> or<01:13:22.159> contract<01:13:22.679> so 01:13:22.910 --> 01:13:22.920 align:start position:0% a deploy maybe a library or contract so 01:13:22.920 --> 01:13:24.830 align:start position:0% a deploy maybe a library or contract so I<01:13:23.000> don't<01:13:23.159> like<01:13:23.440> some<01:13:23.719> kind<01:13:23.880> of<01:13:24.159> precompiled 01:13:24.830 --> 01:13:24.840 align:start position:0% I don't like some kind of precompiled 01:13:24.840 --> 01:13:27.590 align:start position:0% I don't like some kind of precompiled just<01:13:25.199> make<01:13:25.639> a<01:13:25.880> contract<01:13:26.639> that<01:13:26.800> is<01:13:27.040> Computing 01:13:27.590 --> 01:13:27.600 align:start position:0% just make a contract that is Computing 01:13:27.600 --> 01:13:29.270 align:start position:0% just make a contract that is Computing something<01:13:28.000> you<01:13:28.159> deploy<01:13:28.560> it<01:13:28.719> and<01:13:28.840> then<01:13:28.960> you<01:13:29.040> can 01:13:29.270 --> 01:13:29.280 align:start position:0% something you deploy it and then you can 01:13:29.280 --> 01:13:32.110 align:start position:0% something you deploy it and then you can call<01:13:29.760> from<01:13:30.120> solidity<01:13:30.760> you<01:13:30.880> can<01:13:31.040> call<01:13:31.440> this 01:13:32.110 --> 01:13:32.120 align:start position:0% call from solidity you can call this 01:13:32.120 --> 01:13:35.550 align:start position:0% call from solidity you can call this contract<01:13:33.120> but<01:13:33.480> uh<01:13:33.719> yeah<01:13:33.880> like<01:13:34.080> this<01:13:34.239> is<01:13:34.520> highly 01:13:35.550 --> 01:13:35.560 align:start position:0% contract but uh yeah like this is highly 01:13:35.560 --> 01:13:37.870 align:start position:0% contract but uh yeah like this is highly experimental<01:13:36.560> uh<01:13:36.719> it<01:13:36.920> hasn't<01:13:37.239> been<01:13:37.440> updated 01:13:37.870 --> 01:13:37.880 align:start position:0% experimental uh it hasn't been updated 01:13:37.880 --> 01:13:40.629 align:start position:0% experimental uh it hasn't been updated in<01:13:38.040> a<01:13:38.239> year<01:13:39.040> so<01:13:39.639> I<01:13:39.760> think<01:13:39.880> it<01:13:40.000> was<01:13:40.159> more<01:13:40.360> made 01:13:40.629 --> 01:13:40.639 align:start position:0% in a year so I think it was more made 01:13:40.639 --> 01:13:43.750 align:start position:0% in a year so I think it was more made for<01:13:40.840> for<01:13:41.120> fun<01:13:41.440> that<01:13:42.040> than<01:13:42.639> something 01:13:43.750 --> 01:13:43.760 align:start position:0% for for fun that than something 01:13:43.760 --> 01:13:47.709 align:start position:0% for for fun that than something else<01:13:44.760> so<01:13:45.280> are<01:13:45.480> all<01:13:45.679> the<01:13:45.880> tests 01:13:47.709 --> 01:13:47.719 align:start position:0% else so are all the tests 01:13:47.719 --> 01:13:52.790 align:start position:0% else so are all the tests passing 01:13:52.790 --> 01:13:52.800 align:start position:0% 01:13:52.800 --> 01:13:57.669 align:start position:0% no<01:13:53.800> you<01:13:53.920> forgot<01:13:54.280> the<01:13:54.520> unchecked 01:13:57.669 --> 01:13:57.679 align:start position:0% 01:13:57.679 --> 01:14:02.310 align:start position:0% sorry<01:13:58.040> I<01:13:58.600> just<01:13:59.600> I<01:13:59.760> just<01:13:59.920> saw<01:14:00.440> this<01:14:01.440> yeah<01:14:01.920> if<01:14:02.080> you 01:14:02.310 --> 01:14:02.320 align:start position:0% sorry I just I just saw this yeah if you 01:14:02.320 --> 01:14:04.550 align:start position:0% sorry I just I just saw this yeah if you because<01:14:02.719> so<01:14:03.080> basically<01:14:03.520> you<01:14:03.679> have<01:14:03.920> the<01:14:04.120> exact 01:14:04.550 --> 01:14:04.560 align:start position:0% because so basically you have the exact 01:14:04.560 --> 01:14:08.189 align:start position:0% because so basically you have the exact issue<01:14:05.000> that<01:14:05.480> I<01:14:05.600> was<01:14:05.920> explaining<01:14:06.920> so<01:14:07.520> like<01:14:07.880> here 01:14:08.189 --> 01:14:08.199 align:start position:0% issue that I was explaining so like here 01:14:08.199 --> 01:14:10.430 align:start position:0% issue that I was explaining so like here if<01:14:08.280> you<01:14:08.400> don't<01:14:08.639> put<01:14:08.840> the<01:14:09.000> uncheck<01:14:10.000> then<01:14:10.239> the 01:14:10.430 --> 01:14:10.440 align:start position:0% if you don't put the uncheck then the 01:14:10.440 --> 01:14:14.310 align:start position:0% if you don't put the uncheck then the test<01:14:10.719> will<01:14:11.080> revert<01:14:11.880> because<01:14:12.880> um<01:14:13.639> adding<01:14:14.080> these 01:14:14.310 --> 01:14:14.320 align:start position:0% test will revert because um adding these 01:14:14.320 --> 01:14:16.950 align:start position:0% test will revert because um adding these values<01:14:15.040> will<01:14:15.280> cause<01:14:15.520> an<01:14:15.679> overflow<01:14:16.639> and<01:14:16.800> we 01:14:16.950 --> 01:14:16.960 align:start position:0% values will cause an overflow and we 01:14:16.960 --> 01:14:19.790 align:start position:0% values will cause an overflow and we still<01:14:17.159> have<01:14:17.360> like<01:14:17.520> overflow<01:14:18.040> checks<01:14:18.520> in<01:14:18.920> uh<01:14:19.679> uh 01:14:19.790 --> 01:14:19.800 align:start position:0% still have like overflow checks in uh uh 01:14:19.800 --> 01:14:22.390 align:start position:0% still have like overflow checks in uh uh in<01:14:19.960> the 01:14:22.390 --> 01:14:22.400 align:start position:0% 01:14:22.400 --> 01:14:29.350 align:start position:0% test<01:14:23.400> any<01:14:23.639> issues 01:14:29.350 --> 01:14:29.360 align:start position:0% 01:14:29.360 --> 01:14:35.669 align:start position:0% okay<01:14:30.360> all<01:14:30.960> right<01:14:31.960> so<01:14:32.320> we<01:14:32.719> covered<01:14:33.360> the<01:14:33.760> first 01:14:35.669 --> 01:14:35.679 align:start position:0% okay all right so we covered the first 01:14:35.679 --> 01:14:38.550 align:start position:0% okay all right so we covered the first contract<01:14:36.679> uh<01:14:37.280> yeah<01:14:37.600> I<01:14:37.719> have<01:14:37.920> another<01:14:38.239> one<01:14:38.440> if 01:14:38.550 --> 01:14:38.560 align:start position:0% contract

01:15:10.310 --> 01:15:10.320 align:start position:0% uh okay let me okay the code I think the 01:15:10.320 --> 01:15:17.990 align:start position:0% uh okay let me okay the code I think the half<01:15:10.560> code<01:15:11.000> looks 01:15:17.990 --> 01:15:18.000 align:start position:0% 01:15:18.000 --> 01:15:21.510 align:start position:0% great<01:15:19.000> yeah<01:15:19.880> yeah<01:15:20.040> it<01:15:20.360> it<01:15:20.440> doesn't 01:15:21.510 --> 01:15:21.520 align:start position:0% great yeah yeah it it doesn't 01:15:21.520 --> 01:15:31.590 align:start position:0% great yeah yeah it it doesn't matter<01:15:22.520> uh<01:15:22.920> yeah<01:15:23.120> that's<01:15:23.560> unfortunate 01:15:31.590 --> 01:15:31.600 align:start position:0% 01:15:31.600 -->

you<01:15:36.080> can<01:15:36.440> still<01:15:36.920> check<01:15:37.760> uh<01:15:37.920> if<01:15:38.040> you<01:15:38.639> open<01:15:39.639> on 01:15:40.350 --> 01:15:40.360 align:start position:0% uh you can still check uh if you open on 01:15:40.360 --> 01:15:44.070 align:start position:0% uh you can still check uh if you open on uh<01:15:41.360> you<01:15:41.440> can<01:15:41.679> open<01:15:42.080> this<01:15:42.639> uh<01:15:42.840> like<01:15:43.040> a<01:15:43.360> URL<01:15:43.880> in 01:15:44.070 --> 01:15:44.080 align:start position:0% uh you can open this uh like a URL in 01:15:44.080 --> 01:15:45.229 align:start position:0% uh you can open this uh like a URL in your 01:15:45.229 --> 01:15:45.239 align:start position:0% your 01:15:45.239 --> 01:15:47.510 align:start position:0% your browser<01:15:46.239> and<01:15:46.480> you<01:15:46.600> can<01:15:46.800> check<01:15:47.080> or<01:15:47.239> you<01:15:47.320> can 01:15:47.510 --> 01:15:47.520 align:start position:0% browser and you can check or you can 01:15:47.520 --> 01:15:49.629 align:start position:0% browser and you can check or you can change<01:15:47.880> the<01:15:48.040> branch<01:15:48.480> directly<01:15:49.239> I've<01:15:49.400> made 01:15:49.629 --> 01:15:49.639 align:start position:0% change the branch directly I've made 01:15:49.639 --> 01:15:51.390 align:start position:0% change the branch directly I've made another<01:15:50.000> branch<01:15:50.320> called 01:15:51.390 --> 01:15:51.400 align:start position:0% another branch called 01:15:51.400 --> 01:15:54.310 align:start position:0% another branch called finish<01:15:52.400> and<01:15:52.920> you<01:15:53.040> should<01:15:53.360> have<01:15:53.600> the<01:15:53.840> first 01:15:54.310 --> 01:15:54.320 align:start position:0% finish and you should have the first 01:15:54.320 --> 01:15:55.669 align:start position:0% finish and you should have the first test 01:15:55.669 --> 01:15:55.679 align:start position:0% test 01:15:55.679 --> 01:15:58.110 align:start position:0% test uh<01:15:56.239> this<01:15:56.440> one<01:15:56.960> I<01:15:57.040> mean<01:15:57.199> the<01:15:57.360> contract<01:15:57.760> and<01:15:57.960> the 01:15:58.110 --> 01:15:58.120 align:start position:0% uh this one I mean the contract and the 01:15:58.120 --> 01:16:01.110 align:start position:0% uh this one I mean the contract and the test<01:15:58.840> I<01:15:59.000> hope<01:15:59.280> they<01:15:59.400> will<01:15:59.760> work<01:16:00.560> but<01:16:00.760> if<01:16:00.960> they 01:16:01.110 --> 01:16:01.120 align:start position:0% test I hope they will work but if they 01:16:01.120 --> 01:16:02.950 align:start position:0% test I hope they will work but if they don't<01:16:01.440> work<01:16:01.760> maybe<01:16:02.040> there's<01:16:02.239> a<01:16:02.360> bug<01:16:02.600> in<01:16:02.719> my 01:16:02.950 --> 01:16:02.960 align:start position:0% don't work maybe there's a bug in my 01:16:02.960 --> 01:16:05.550 align:start position:0% don't work maybe there's a bug in my code<01:16:03.360> I<01:16:03.440> don't<01:16:03.639> know<01:16:04.320> so<01:16:04.639> if<01:16:04.719>

position:0% code I don't know so if you can find it then<01:16:06.239> that<01:16:06.360> would<01:16:06.560> be<01:16:07.239> amazing<01:16:08.239> maybe<01:16:08.520> I<01:16:08.679> made 01:16:08.830 --> 01:16:08.840 align:start position:0% then that would be amazing maybe I made 01:16:08.840 --> 01:16:10.910 align:start position:0% then that would be amazing maybe I made a<01:16:09.000> mistake 01:16:10.910 --> 01:16:10.920 align:start position:0% a mistake 01:16:10.920 --> 01:16:14.149 align:start position:0% a mistake somewhere<01:16:11.920> yeah<01:16:12.320>

I'm<01:20:30.080> not<01:20:30.280> sure<01:20:30.719> exactly<01:20:31.639> check<01:20:31.880> on 01:20:32.070 --> 01:20:32.080 align:start position:0% yeah I'm I'm not sure exactly check on 01:20:32.080 --> 01:20:34.310 align:start position:0% yeah I'm I'm not sure exactly check on the<01:20:32.280> other<01:20:32.520> Branch<01:20:33.480> uh<01:20:33.600> you<01:20:33.679> can<01:20:33.840> switch<01:20:34.159> the 01:20:34.310 --> 01:20:34.320 align:start position:0% the other Branch uh you can switch the 01:20:34.320 --> 01:20:38.070 align:start position:0% the other Branch uh you can switch the branch<01:20:34.800> go<01:20:34.960> to<01:20:35.120> the<01:20:35.280> finished<01:20:35.639> Branch<01:20:36.040> if<01:20:36.159> you 01:20:38.070 --> 01:20:38.080 align:start position:0% branch go to the finished Branch if you 01:20:38.080 --> 01:20:40.950 align:start position:0% branch go to the finished Branch if you want<01:20:39.080> uh<01:20:39.400> yeah<01:20:39.600> if<01:20:39.760> it<01:20:39.920> doesn't<01:20:40.239> work<01:20:40.480> after<01:20:40.800> I 01:20:40.950 --> 01:20:40.960 align:start position:0% want uh yeah if it doesn't work after I 01:20:40.960 --> 01:20:43.990 align:start position:0% want uh yeah if it doesn't work after I can<01:20:41.320> I<01:20:41.440> can<01:20:41.600> look<01:20:41.760> into<01:20:42.520> but<01:20:42.920> I<01:20:43.000> think<01:20:43.520> we<01:20:43.920> we 01:20:43.990 --> 01:20:44.000 align:start position:0% can I can look into but I think we we 01:20:44.000 --> 01:20:46.149 align:start position:0% can I can look into but I think we we are<01:20:44.120> going<01:20:44.280> to<01:20:44.440> move<01:20:44.639> forward<01:20:45.159> because<01:20:45.920> feel 01:20:46.149 --> 01:20:46.159 align:start position:0% are going to move forward because feel 01:20:46.159 --> 01:20:48.910 align:start position:0% are going to move forward because feel like<01:20:46.320> you<01:20:46.520> guys<01:20:47.360> have<01:20:47.639> the<01:20:47.920> code 01:20:48.910 --> 01:20:48.920 align:start position:0% like you guys have the code 01:20:48.920 --> 01:20:51.950 align:start position:0% like you guys have the code working<01:20:49.920> uh<01:20:50.120> so<01:20:50.480> yeah<01:20:50.679> we<01:20:50.840> still<01:20:51.159> have<01:20:51.360> like<01:20:51.560> 40 01:20:51.950 --> 01:20:51.960 align:start position:0% working uh so yeah we still have like 40 01:20:51.960 --> 01:20:54.870 align:start position:0% working uh so yeah we still have like 40 minutes<01:20:52.639> so<01:20:52.880> maybe<01:20:53.159> we<01:20:53.320> can<01:20:54.080> go<01:20:54.639> through 01:20:54.870 --> 01:20:54.880 align:start position:0% minutes so maybe we can go through 01:20:54.880 --> 01:20:56.070 align:start position:0% minutes so maybe we can go through another 01:20:56.070 --> 01:20:56.080 align:start position:0% another 01:20:56.080 --> 01:20:58.950 align:start position:0% another contract 01:20:58.950 --> 01:20:58.960 align:start position:0% contract 01:20:58.960 --> 01:21:04.270 align:start position:0% contract uh<01:20:59.960> yes<01:21:00.199> so<01:21:00.639> this<01:21:00.880> one<01:21:01.480> is<01:21:02.320> more<01:21:02.600> or<01:21:03.000> less<01:21:04.000> the 01:21:04.270 --> 01:21:04.280 align:start position:0% uh yes so this one is more or less the 01:21:04.280 --> 01:21:06.470 align:start position:0% uh yes so this one is more or less the same<01:21:04.639> thing<01:21:05.400> it's<01:21:05.520> not<01:21:05.760> exactly<01:21:06.159> the<01:21:06.280> same 01:21:06.470 --> 01:21:06.480 align:start position:0% same thing it's not exactly the same 01:21:06.480 --> 01:21:08.590 align:start position:0% same thing it's not exactly the same thing<01:21:06.719> but<01:21:06.880> we<01:21:07.000> are<01:21:07.159> going<01:21:07.360> to<01:21:07.560> cover<01:21:08.239> one 01:21:08.590 --> 01:21:08.600 align:start position:0% thing but we are going to cover one 01:21:08.600 --> 01:21:12.750 align:start position:0% thing but we are going to cover one extra<01:21:09.560> uh<01:21:10.239> one<01:21:10.639> extra<01:21:11.080> op<01:21:11.400> code<01:21:11.719> so<01:21:12.120> now<01:21:12.560> in 01:21:12.750 --> 01:21:12.760 align:start position:0% extra uh one extra op code so now in 01:21:12.760 --> 01:21:15.030 align:start position:0% extra uh one extra op code so now in this<01:21:12.960> case<01:21:13.280> what<01:21:13.400> we<01:21:13.520> want<01:21:13.719> to<01:21:13.880> do<01:21:14.120> is 01:21:15.030 --> 01:21:15.040 align:start position:0% this case what we want to do is 01:21:15.040 --> 01:21:18.910 align:start position:0% this case what we want to do is that<01:21:16.040> we<01:21:16.880> you<01:21:16.960> will<01:21:17.120> see<01:21:17.320> it's<01:21:17.520> very<01:21:17.760> simple<01:21:18.520> we 01:21:18.910 --> 01:21:18.920 align:start position:0% that we you will see it's very simple we 01:21:18.920 --> 01:21:22.590 align:start position:0% that we you will see it's very simple we just<01:21:19.080> want<01:21:19.320> to<01:21:19.560> be<01:21:19.840> able<01:21:20.320> to<01:21:21.320> get<01:21:21.639> a<01:21:21.920> value<01:21:22.400> from 01:21:22.590 --> 01:21:22.600 align:start position:0% just want to be able to get a value from 01:21:22.600 --> 01:21:26.790 align:start position:0% just want to be able to get a value from the<01:21:22.800> sender<01:21:23.800> and<01:21:24.040> store<01:21:24.639> this<01:21:24.920> value<01:21:25.920> and<01:21:26.639> if 01:21:26.790 --> 01:21:26.800 align:start position:0% the sender and store this value and if 01:21:26.800 --> 01:21:29.149 align:start position:0% the sender and store this value and if the<01:21:26.960> sender<01:21:27.400> wants<01:21:27.679> to<01:21:27.920> read<01:21:28.239> this<01:21:28.480> value<01:21:28.880> then 01:21:29.149 --> 01:21:29.159 align:start position:0% the sender wants to read this value then 01:21:29.159 --> 01:21:31.950 align:start position:0% the sender wants to read this value then we<01:21:29.280> are<01:21:29.880> just<01:21:30.080> going<01:21:30.280> to<01:21:30.639> return<01:21:30.840> it<01:21:31.400> so<01:21:31.679> once 01:21:31.950 --> 01:21:31.960 align:start position:0% we are just going to return it so once 01:21:31.960 --> 01:21:34.750 align:start position:0% we are just going to return it so once again<01:21:32.320> very<01:21:32.760> very<01:21:33.080> basic<01:21:33.480> contract<01:21:34.360> but<01:21:34.600> this 01:21:34.750 --> 01:21:34.760 align:start position:0% again very very basic contract but this 01:21:34.760 --> 01:21:38.550 align:start position:0% again very very basic contract but this will<01:21:35.159> allow<01:21:35.520> us<01:21:35.920> to<01:21:36.920> uh<01:21:37.159> cover<01:21:38.159> a<01:21:38.280> few 01:21:38.550 --> 01:21:38.560 align:start position:0% will allow us to uh cover a few 01:21:38.560 --> 01:21:40.310 align:start position:0% will allow us to uh cover a few different 01:21:40.310 --> 01:21:40.320 align:start position:0% different 01:21:40.320 --> 01:21:44.390 align:start position:0% different things<01:21:41.320> so<01:21:41.760> in<01:21:42.000> this<01:21:42.520> case<01:21:43.520> well<01:21:43.920> we<01:21:44.040> are<01:21:44.199> going 01:21:44.390 --> 01:21:44.400 align:start position:0% things so in this case well we are going 01:21:44.400 --> 01:21:47.310 align:start position:0% things so in this case well we are going to<01:21:44.679> start<01:21:45.040> by<01:21:45.239> the<01:21:45.480> interface<01:21:46.480> definition 01:21:47.310 --> 01:21:47.320 align:start position:0% to start by the interface definition 01:21:47.320 --> 01:21:49.790 align:start position:0% to start by the interface definition once<01:21:47.639> again<01:21:48.280> so<01:21:48.560> we<01:21:48.679> are<01:21:48.800> going<01:21:49.000> to<01:21:49.199> Define<01:21:49.560> two 01:21:49.790 --> 01:21:49.800 align:start position:0% once again so we are going to Define two 01:21:49.800 --> 01:21:53.990 align:start position:0% once again so we are going to Define two values<01:21:50.719> the<01:21:50.920> first<01:21:51.280> value<01:21:51.679> is<01:21:52.000> just<01:21:53.000> uh<01:21:53.719> two 01:21:53.990 --> 01:21:54.000 align:start position:0% values the first value is just uh two 01:21:54.000 --> 01:21:56.229 align:start position:0% values the first value is just uh two functions<01:21:54.600> sorry<01:21:55.239> and<01:21:55.400> the<01:21:55.560> first<01:21:55.880> function 01:21:56.229 --> 01:21:56.239 align:start position:0% functions sorry and the first function 01:21:56.239 --> 01:21:59.550 align:start position:0% functions sorry and the first function is<01:21:56.480> just<01:21:56.840> set<01:21:57.199> value<01:21:58.159> so<01:21:58.400> in<01:21:58.560> this<01:21:58.800> case<01:21:59.360> we 01:21:59.550 --> 01:21:59.560 align:start position:0% is just set value so in this case we 01:21:59.560 --> 01:22:03.669 align:start position:0% is just set value so in this case we want<01:22:00.199> well<01:22:00.560> U<01:22:00.800> into<01:22:01.760> 56<01:22:02.679> which<01:22:02.800> is 01:22:03.669 --> 01:22:03.679 align:start position:0% want well U into 56 which is 01:22:03.679 --> 01:22:06.669 align:start position:0% want well U into 56 which is very<01:22:04.760> original<01:22:05.760> and<01:22:05.960> then<01:22:06.120> we're<01:22:06.320> just<01:22:06.480> going 01:22:06.669 --> 01:22:06.679 align:start position:0% very original and then we're just going 01:22:06.679 --> 01:22:09.790 align:start position:0% very original and then we're just going to<01:22:06.880> make<01:22:07.159> like<01:22:07.480> another<01:22:08.000> function<01:22:08.679> called<01:22:09.239> get 01:22:09.790 --> 01:22:09.800 align:start position:0% to make like another function called get 01:22:09.800 --> 01:22:13.310 align:start position:0% to make like another function called get value<01:22:10.760> and<01:22:11.000> in<01:22:11.239> this<01:22:11.480> case<01:22:11.800> we<01:22:11.960> don't<01:22:12.159> want<01:22:12.400> to 01:22:13.310 --> 01:22:13.320 align:start position:0% value and in this case we don't want to 01:22:13.320 --> 01:22:15.830 align:start position:0% value and in this case we don't want to get<01:22:13.600> we<01:22:13.679> don't<01:22:13.880> want<01:22:14.080> to<01:22:14.320> set<01:22:14.840> something<01:22:15.679> but 01:22:15.830 --> 01:22:15.840 align:start position:0% get we don't want to set something but 01:22:15.840 --> 01:22:18.790 align:start position:0% get we don't want to set something but we<01:22:15.960> want<01:22:16.159> to<01:22:16.760> return 01:22:18.790 --> 01:22:18.800 align:start position:0% we want to return 01:22:18.800 --> 01:22:22.669 align:start position:0% we want to return something<01:22:19.800> and<01:22:20.320> then<01:22:20.679> we<01:22:20.880> are<01:22:21.280> going<01:22:21.560> to<01:22:22.040> cover 01:22:22.669 --> 01:22:22.679 align:start position:0% something and then we are going to cover 01:22:22.679 --> 01:22:24.550 align:start position:0% something and then we are going to cover something<01:22:23.239> else<01:22:23.639> so<01:22:23.840> we<01:22:23.960> are<01:22:24.080> going<01:22:24.239> to<01:22:24.360> make 01:22:24.550 --> 01:22:24.560 align:start position:0% something else so we are going to make 01:22:24.560 --> 01:22:27.790 align:start position:0% something else so we are going to make make<01:22:24.800> a<01:22:24.920> new<01:22:25.199> constant<01:22:25.760> called<01:22:26.560> uh<01:22:26.800> value 01:22:27.790 --> 01:22:27.800 align:start position:0% make a new constant called uh value 01:22:27.800 --> 01:22:31.149 align:start position:0% make a new constant called uh value location<01:22:28.800> and<01:22:29.120> so<01:22:29.520> we<01:22:29.639> are<01:22:29.800> going<01:22:29.960> to<01:22:30.159> use<01:22:30.520> this 01:22:31.149 --> 01:22:31.159 align:start position:0% location and so we are going to use this 01:22:31.159 --> 01:22:34.149 align:start position:0% location and so we are going to use this which<01:22:31.320> is<01:22:31.520> like<01:22:31.920> a<01:22:32.920> yeah<01:22:33.320> some<01:22:33.600> kind<01:22:33.760> of 01:22:34.149 --> 01:22:34.159 align:start position:0% which is like a yeah some kind of 01:22:34.159 --> 01:22:37.149 align:start position:0% which is like a yeah some kind of built-in<01:22:34.800> function<01:22:35.719> that<01:22:35.920> we<01:22:36.159> haven't<01:22:36.480> seen 01:22:37.149 --> 01:22:37.159 align:start position:0% built-in function that we haven't seen 01:22:37.159 --> 01:22:40.030 align:start position:0% built-in function that we haven't seen yet<01:22:37.880> called<01:22:38.239> free<01:22:38.719> storage 01:22:40.030 --> 01:22:40.040 align:start position:0% yet called free storage 01:22:40.040 --> 01:22:43.110 align:start position:0% yet called free storage pointer<01:22:41.040> and<01:22:41.280> basically<01:22:41.920> what<01:22:42.280> this<01:22:42.560> function 01:22:43.110 --> 01:22:43.120 align:start position:0% pointer and basically what this function 01:22:43.120 --> 01:22:45.550 align:start position:0% pointer and basically what this function does<01:22:44.040> uh<01:22:44.159> it's<01:22:44.400> very<01:22:44.639> simple<01:22:45.040> it's<01:22:45.199> just<01:22:45.360> going 01:22:45.550 --> 01:22:45.560 align:start position:0% does uh it's very simple it's just going 01:22:45.560 --> 01:22:49.229 align:start position:0% does uh it's very simple it's just going to<01:22:45.840> give<01:22:46.040> you<01:22:47.040> uh<01:22:47.360> the<01:22:47.600> location<01:22:48.280> a<01:22:48.480> location 01:22:49.229 --> 01:22:49.239 align:start position:0% to give you uh the location a location 01:22:49.239 --> 01:22:52.870 align:start position:0% to give you uh the location a location where<01:22:50.239> uh<01:22:50.520> the<01:22:50.679> storage<01:22:51.440> is<01:22:51.600> free<01:22:52.280> so<01:22:52.520> in<01:22:52.679> this 01:22:52.870 --> 01:22:52.880 align:start position:0% where uh the storage is free so in this 01:22:52.880 --> 01:22:56.149 align:start position:0% where uh the storage is free so in this case<01:22:53.159> if<01:22:53.280> we<01:22:53.440> call<01:22:53.679> it<01:22:54.120> now<01:22:54.880> it<01:22:55.000> will<01:22:55.159> be<01:22:55.440> zero 01:22:56.149 --> 01:22:56.159 align:start position:0% case if we call it now it will be zero 01:22:56.159 --> 01:22:59.229 align:start position:0% case if we call it now it will be zero because<01:22:56.560> the<01:22:57.159> first<01:22:58.159> uh<01:22:58.440> location<01:22:58.960> that<01:22:59.080> is 01:22:59.229 --> 01:22:59.239 align:start position:0% because the first uh location that is 01:22:59.239 --> 01:23:02.590 align:start position:0% because the first uh location that is free<01:22:59.920> is<01:23:00.239> located<01:23:00.760> at<01:23:01.080> index<01:23:01.760> zero<01:23:02.280> very 01:23:02.590 --> 01:23:02.600 align:start position:0% free is located at index zero very 01:23:02.600 --> 01:23:04.870 align:start position:0% free is located at index zero very simple<01:23:03.320> if<01:23:03.400> you<01:23:03.560> call<01:23:03.800> it<01:23:04.040> again<01:23:04.440> it<01:23:04.560> will<01:23:04.719> be 01:23:04.870 --> 01:23:04.880 align:start position:0% simple if you call it again it will be 01:23:04.880 --> 01:23:08.830 align:start position:0% simple if you call it again it will be one<01:23:05.400> because<01:23:06.239> we<01:23:06.480> have<01:23:07.040> this<01:23:07.440> value<01:23:07.960> already 01:23:08.830 --> 01:23:08.840 align:start position:0% one because we have this value already 01:23:08.840 --> 01:23:11.390 align:start position:0% one because we have this value already taking<01:23:09.280> the<01:23:09.440> first<01:23:09.760> slot<01:23:10.080> so<01:23:10.280> the<01:23:10.480> slot<01:23:10.760> zero 01:23:11.390 --> 01:23:11.400 align:start position:0% taking the first slot so the slot zero 01:23:11.400 --> 01:23:14.110 align:start position:0% taking the first slot so the slot zero and<01:23:11.520> then<01:23:11.719> after<01:23:12.120> we<01:23:12.239> can<01:23:12.520> take<01:23:13.000> the<01:23:13.159> slot<01:23:13.520> zero 01:23:14.110 --> 01:23:14.120 align:start position:0% and then after we can take the slot zero 01:23:14.120 --> 01:23:16.550 align:start position:0% and then after we can take the slot zero one<01:23:14.480> two 01:23:16.550 --> 01:23:16.560 align:start position:0% one two 01:23:16.560 --> 01:23:19.550 align:start position:0% one two Etc<01:23:17.560> any<01:23:18.120> questions 01:23:19.550 --> 01:23:19.560 align:start position:0% Etc any questions 01:23:19.560 --> 01:23:21.870 align:start position:0% Etc any questions no<01:23:20.560> all 01:23:21.870 --> 01:23:21.880 align:start position:0% no all 01:23:21.880 --> 01:23:26.229 align:start position:0% no all right<01:23:23.159> um<01:23:24.159> and<01:23:24.840> then<01:23:25.280> we<01:23:25.400> are<01:23:25.600> going<01:23:25.800> to<01:23:26.000> go 01:23:26.229 --> 01:23:26.239 align:start position:0% right um and then we are going to go 01:23:26.239 --> 01:23:30.550 align:start position:0% right um and then we are going to go directly<01:23:26.639> to<01:23:26.800> the<01:23:26.960> main<01:23:27.760> entry<01:23:28.320> point<01:23:29.360> so<01:23:30.360> this 01:23:30.550 --> 01:23:30.560 align:start position:0% directly to the main entry point so this 01:23:30.560 --> 01:23:33.790 align:start position:0% directly to the main entry point so this is<01:23:30.800> going<01:23:31.040> to<01:23:31.239> be<01:23:32.199> almost<01:23:32.639> the<01:23:32.800> same<01:23:33.080> code<01:23:33.560> as 01:23:33.790 --> 01:23:33.800 align:start position:0% is going to be almost the same code as 01:23:33.800 --> 01:23:35.750 align:start position:0% is going to be almost the same code as we<01:23:34.520> as<01:23:34.679> we<01:23:34.840> did 01:23:35.750 --> 01:23:35.760 align:start position:0% we as we did 01:23:35.760 --> 01:23:39.830 align:start position:0% we as we did actually<01:23:36.760> so<01:23:37.679> we<01:23:37.840> are<01:23:38.040> loading<01:23:38.520> the<01:23:38.719> C<01:23:39.000> data 01:23:39.830 --> 01:23:39.840 align:start position:0% actually so we are loading the C data 01:23:39.840 --> 01:23:42.870 align:start position:0% actually so we are loading the C data from<01:23:40.080> the<01:23:40.239> start<01:23:41.120> we<01:23:41.239> are<01:23:41.600> shifting<01:23:42.159> to<01:23:42.320> the 01:23:42.870 --> 01:23:42.880 align:start position:0% from the start we are shifting to the 01:23:42.880 --> 01:23:47.110 align:start position:0% from the start we are shifting to the right<01:23:43.880> uh<01:23:44.080> 28<01:23:45.080> bytes<01:23:46.080> and<01:23:46.480> what<01:23:46.600> is<01:23:46.760> going<01:23:46.920> to 01:23:47.110 --> 01:23:47.120 align:start position:0% right uh 28 bytes and what is going to 01:23:47.120 --> 01:23:50.229 align:start position:0% right uh 28 bytes and what is going to happen<01:23:47.560> here<01:23:48.000> that<01:23:48.920> uh<01:23:49.120> I<01:23:49.199> told<01:23:49.440> you<01:23:49.679> earlier 01:23:50.229 --> 01:23:50.239 align:start position:0% happen here that uh I told you earlier 01:23:50.239 --> 01:23:52.470 align:start position:0% happen here that uh I told you earlier that<01:23:50.400> we<01:23:50.520> don't<01:23:50.760> care<01:23:50.960> about<01:23:51.280> the<01:23:52.159> uh 01:23:52.470 --> 01:23:52.480 align:start position:0% that we don't care about the uh 01:23:52.480 --> 01:23:54.430 align:start position:0% that we don't care about the uh duplicate<01:23:53.080> one<01:23:53.320> the<01:23:53.440> DB<01:23:53.760> one<01:23:54.040> but<01:23:54.159> in<01:23:54.320> this 01:23:54.430 --> 01:23:54.440 align:start position:0% duplicate one the DB one but in this 01:23:54.440 --> 01:23:57.390 align:start position:0% duplicate one the DB one but in this this<01:23:54.600> case<01:23:54.840> we<01:23:54.960> need<01:23:55.400> it<01:23:56.400> because<01:23:57.120> what<01:23:57.239> is 01:23:57.390 --> 01:23:57.400 align:start position:0% this case we need it because what is 01:23:57.400 --> 01:24:01.550 align:start position:0% this case we need it because what is going<01:23:57.560> to<01:23:57.760> happen<01:23:58.120> here<01:23:58.600> that<01:23:59.600> here<01:24:00.159> we<01:24:00.560> have 01:24:01.550 --> 01:24:01.560 align:start position:0% going to happen here that here we have 01:24:01.560 --> 01:24:04.790 align:start position:0% going to happen here that here we have the<01:24:02.000> function<01:24:03.000> signature<01:24:03.840> that<01:24:04.000> we<01:24:04.480> received 01:24:04.790 --> 01:24:04.800 align:start position:0% the function signature that we received 01:24:04.800 --> 01:24:07.470 align:start position:0% the function signature that we received from<01:24:05.199> the<01:24:05.400> sender<01:24:06.040> in<01:24:06.199> the 01:24:07.470 --> 01:24:07.480 align:start position:0% from the sender in the 01:24:07.480 --> 01:24:11.390 align:start position:0% from the sender in the stack<01:24:08.480> and<01:24:08.880> we<01:24:09.040> want<01:24:09.280> to<01:24:09.679> keep<01:24:09.960> it<01:24:10.400> for<01:24:10.679> later 01:24:11.390 --> 01:24:11.400 align:start position:0% stack and we want to keep it for later 01:24:11.400 --> 01:24:14.590 align:start position:0% stack and we want to keep it for later so<01:24:11.679> we<01:24:11.800> are<01:24:12.040> going<01:24:12.320> to<01:24:12.880> duplicate<01:24:13.480> it<01:24:14.199> so<01:24:14.480> what 01:24:14.590 --> 01:24:14.600 align:start position:0% so we are going to duplicate it so what 01:24:14.600 --> 01:24:16.709 align:start position:0% so we are going to duplicate it so what is<01:24:14.760> going<01:24:14.920> to<01:24:15.120> happen<01:24:15.440> is<01:24:15.560> that<01:24:15.760> we<01:24:15.880> will<01:24:16.159> have 01:24:16.709 --> 01:24:16.719 align:start position:0% is going to happen is that we will have 01:24:16.719 --> 01:24:19.910 align:start position:0% is going to happen is that we will have two<01:24:17.520> times<01:24:18.360> the<01:24:18.520> function<01:24:18.920> signature<01:24:19.480> we 01:24:19.910 --> 01:24:19.920 align:start position:0% two times the function signature we 01:24:19.920 --> 01:24:21.470 align:start position:0% two times the function signature we received<01:24:20.199> from<01:24:20.600> the 01:24:21.470 --> 01:24:21.480 align:start position:0% received from the 01:24:21.480 --> 01:24:24.550 align:start position:0% received from the sender<01:24:22.480> then<01:24:22.639> we're<01:24:22.880> just<01:24:23.080> going<01:24:23.239> to<01:24:23.400> be<01:24:23.560> doing 01:24:24.550 --> 01:24:24.560 align:start position:0% sender then we're just going to be doing 01:24:24.560 --> 01:24:27.149 align:start position:0% sender then we're just going to be doing exactly<01:24:25.080> what<01:24:25.239> we<01:24:25.400> did<01:24:25.760> earlier<01:24:26.440> so<01:24:26.800> we<01:24:26.960> are 01:24:27.149 --> 01:24:27.159 align:start position:0% exactly what we did earlier so we are 01:24:27.159 --> 01:24:31.669 align:start position:0% exactly what we did earlier so we are going<01:24:27.440> to<01:24:28.000> load<01:24:29.000> uh<01:24:29.159> for<01:24:29.600> example<01:24:30.600> the<01:24:30.840> first 01:24:31.669 --> 01:24:31.679 align:start position:0% going to load uh for example the first 01:24:31.679 --> 01:24:35.470 align:start position:0% going to load uh for example the first set<01:24:32.679> value<01:24:33.560> the<01:24:33.760> signature<01:24:34.239> of<01:24:34.360> the<01:24:34.520> set<01:24:34.760> value 01:24:35.470 --> 01:24:35.480 align:start position:0% set value the signature of the set value 01:24:35.480 --> 01:24:38.910 align:start position:0% set value the signature of the set value function<01:24:36.480> so<01:24:36.960> we<01:24:37.120> want<01:24:37.280> to<01:24:37.440> check<01:24:37.880> okay<01:24:38.159> maybe 01:24:38.910 --> 01:24:38.920 align:start position:0% function so we want to check okay maybe 01:24:38.920 --> 01:24:42.350 align:start position:0% function so we want to check okay maybe the<01:24:39.159> sender<01:24:40.040> they<01:24:40.159> want<01:24:40.480> to<01:24:41.159> set<01:24:41.480> the<01:24:41.679> value 01:24:42.350 --> 01:24:42.360 align:start position:0% the sender they want to set the value 01:24:42.360 --> 01:24:45.229 align:start position:0% the sender they want to set the value okay<01:24:42.600> let<01:24:42.800> let's<01:24:43.000> see<01:24:43.639> so<01:24:44.119> yeah<01:24:44.320> we<01:24:44.520> load<01:24:45.000> the 01:24:45.229 --> 01:24:45.239 align:start position:0% okay let let's see so yeah we load the 01:24:45.239 --> 01:24:48.590 align:start position:0% okay let let's see so yeah we load the set<01:24:45.560> value<01:24:46.080> function<01:24:46.480> signature<01:24:47.400> and<01:24:47.560> we<01:24:47.719> do 01:24:48.590 --> 01:24:48.600 align:start position:0% set value function signature and we do 01:24:48.600 --> 01:24:52.310 align:start position:0% set value function signature and we do equal<01:24:49.600> and<01:24:50.440> yeah<01:24:50.679> maybe<01:24:50.960> it's<01:24:51.159> equal<01:24:51.760> maybe 01:24:52.310 --> 01:24:52.320 align:start position:0% equal and yeah maybe it's equal maybe 01:24:52.320 --> 01:24:55.189 align:start position:0% equal and yeah maybe it's equal maybe it's<01:24:52.560> not<01:24:52.840> we<01:24:52.920> don't<01:24:53.159> know<01:24:53.639> so<01:24:53.840> we<01:24:54.000> said<01:24:54.639> okay 01:24:55.189 --> 01:24:55.199 align:start position:0% it's not we don't know so we said okay 01:24:55.199 --> 01:25:00.030 align:start position:0% it's not we don't know so we said okay you<01:24:55.360> can<01:24:55.639> jump<01:24:56.639> to<01:24:57.040> set<01:24:58.080> if<01:24:59.080> the<01:24:59.239> value<01:24:59.600> that<01:24:59.760> we 01:25:00.030 --> 01:25:00.040 align:start position:0% you can jump to set if the value that we 01:25:00.040 --> 01:25:03.990 align:start position:0% you can jump to set if the value that we just<01:25:00.600> received<01:25:01.000> is<01:25:02.000> uh<01:25:02.239> equal<01:25:02.600> to<01:25:02.760> set<01:25:03.080> value 01:25:03.990 --> 01:25:04.000 align:start position:0% just received is uh equal to set value 01:25:04.000 --> 01:25:06.430 align:start position:0% just received is uh equal to set value and<01:25:04.280> then<01:25:04.679> you<01:25:04.800> know<01:25:04.960> the<01:25:05.080> drill<01:25:05.760> it<01:25:05.840> will<01:25:06.080> do 01:25:06.430 --> 01:25:06.440 align:start position:0% and then you know the drill it will do 01:25:06.440 --> 01:25:08.470 align:start position:0% and then you know the drill it will do it<01:25:06.520> will<01:25:06.719> go<01:25:07.040> here<01:25:07.320> and<01:25:07.520> then<01:25:07.760> to<01:25:07.960> the<01:25:08.080> macro 01:25:08.470 --> 01:25:08.480 align:start position:0% it will go here and then to the macro 01:25:08.480 --> 01:25:12.590 align:start position:0% it will go here and then to the macro set<01:25:08.760> value<01:25:09.520> and<01:25:09.639> it<01:25:09.760> will<01:25:10.159> go<01:25:11.360> here<01:25:12.360> but<01:25:12.480> if 01:25:12.590 --> 01:25:12.600 align:start position:0% set value and it will go here but if 01:25:12.600 --> 01:25:14.709 align:start position:0% set value and it will go here but if it's<01:25:12.800> not<01:25:13.040> the<01:25:13.199> case<01:25:13.840> then<01:25:14.040> what<01:25:14.159> is<01:25:14.320> going<01:25:14.480> to 01:25:14.709 --> 01:25:14.719 align:start position:0% it's not the case then what is going to 01:25:14.719 --> 01:25:18.189 align:start position:0% it's not the case then what is going to happen<01:25:15.080> is<01:25:15.280> that<01:25:15.920> well<01:25:16.480> jumpy<01:25:17.280> is<01:25:17.520> just<01:25:17.719> going 01:25:18.189 --> 01:25:18.199 align:start position:0% happen is that well jumpy is just going 01:25:18.199 --> 01:25:21.669 align:start position:0% happen is that well jumpy is just going to<01:25:19.199> do<01:25:19.440> nothing<01:25:20.199> and<01:25:20.440> so<01:25:20.840> we<01:25:20.960> will<01:25:21.199> go<01:25:21.400> back 01:25:21.669 --> 01:25:21.679 align:start position:0% to do nothing and so we will go back 01:25:21.679 --> 01:25:26.030 align:start position:0% to do nothing and so we will go back here<01:25:22.600> and<01:25:22.960> in<01:25:23.159> this<01:25:23.400> case<01:25:23.719> also<01:25:24.600> dump<01:25:25.000> one<01:25:25.760> here 01:25:26.030 --> 01:25:26.040 align:start position:0% here and in this case also dump one here 01:25:26.040 --> 01:25:29.109 align:start position:0% here and in this case also dump one here like<01:25:26.320> dump<01:25:26.560> one<01:25:26.760> sorry<01:25:27.040> is<01:25:27.400> not<01:25:27.639> needed<01:25:28.159> but 01:25:29.109 --> 01:25:29.119 align:start position:0% like dump one sorry is not needed but 01:25:29.119 --> 01:25:31.830 align:start position:0% like dump one sorry is not needed but yeah<01:25:29.880> don't<01:25:30.080> worry<01:25:30.320> about<01:25:30.560> it<01:25:30.800> but<01:25:31.320> this<01:25:31.440> means 01:25:31.830 --> 01:25:31.840 align:start position:0% yeah don't worry about it but this means 01:25:31.840 --> 01:25:33.310 align:start position:0% yeah don't worry about it but this means that 01:25:33.310 --> 01:25:33.320 align:start position:0% that 01:25:33.320 --> 01:25:37.149 align:start position:0% that here<01:25:34.320> uh<01:25:34.600> when<01:25:34.800> we<01:25:35.040> called<01:25:35.600> equal<01:25:36.440> we<01:25:36.880> we 01:25:37.149 --> 01:25:37.159 align:start position:0% here uh when we called equal we we 01:25:37.159 --> 01:25:41.390 align:start position:0% here uh when we called equal we we consume<01:25:38.080> the<01:25:38.440> first<01:25:38.880> value<01:25:39.480> that<01:25:39.639> we<01:25:39.800> loaded 01:25:41.390 --> 01:25:41.400 align:start position:0% consume the first value that we loaded 01:25:41.400 --> 01:25:45.109 align:start position:0% consume the first value that we loaded here<01:25:42.400> and<01:25:42.679> we<01:25:42.880> consume<01:25:43.440> this<01:25:43.639> value<01:25:43.920> too<01:25:44.679> so 01:25:45.109 --> 01:25:45.119 align:start position:0% here and we consume this value too so 01:25:45.119 --> 01:25:48.070 align:start position:0% here and we consume this value too so luckily<01:25:46.000> we<01:25:46.320> duplicated<01:25:47.159> this<01:25:47.360> value<01:25:47.800> into 01:25:48.070 --> 01:25:48.080 align:start position:0% luckily we duplicated this value into 01:25:48.080 --> 01:25:51.189 align:start position:0% luckily we duplicated this value into the<01:25:48.320> stack<01:25:49.040> so<01:25:49.239> this<01:25:49.400> means<01:25:49.639> that<01:25:49.840> we<01:25:50.199> have 01:25:51.189 --> 01:25:51.199 align:start position:0% the stack so this means that we have 01:25:51.199 --> 01:25:53.950 align:start position:0% the stack so this means that we have value<01:25:51.600> a<01:25:52.360> two<01:25:52.600> times<01:25:52.920> the<01:25:53.040> value<01:25:53.320> a<01:25:53.719> then<01:25:53.880> the 01:25:53.950 --> 01:25:53.960 align:start position:0% value a two times the value a then the 01:25:53.960 --> 01:25:56.790 align:start position:0% value a two times the value a then the value<01:25:54.400> B<01:25:55.000> then<01:25:55.159> they<01:25:55.239> are<01:25:55.520> consumed<01:25:56.239> so<01:25:56.440> we<01:25:56.560> are 01:25:56.790 --> 01:25:56.800 align:start position:0% value B then they are consumed so we are 01:25:56.800 --> 01:26:00.430 align:start position:0% value B then they are consumed so we are left<01:25:57.199> with<01:25:57.400> the<01:25:57.560> value<01:25:57.880> a<01:25:58.760> so<01:25:59.760> then<01:26:00.119> we<01:26:00.239> can 01:26:00.430 --> 01:26:00.440 align:start position:0% left with the value a so then we can 01:26:00.440 --> 01:26:03.070 align:start position:0% left with the value a so then we can load<01:26:00.719> the<01:26:00.920> function<01:26:01.320> signature<01:26:01.800> of<01:26:02.000> get<01:26:02.320> value 01:26:03.070 --> 01:26:03.080 align:start position:0% load the function signature of get value 01:26:03.080 --> 01:26:05.709 align:start position:0% load the function signature of get value then<01:26:03.239> we<01:26:03.400> have<01:26:03.560> the<01:26:03.760> value<01:26:04.360> a<01:26:05.280> and<01:26:05.560> the 01:26:05.709 --> 01:26:05.719 align:start position:0% then we have the value a and the 01:26:05.719 --> 01:26:07.790 align:start position:0% then we have the value a and the signature<01:26:06.239> of<01:26:06.560> get<01:26:06.800> value<01:26:07.239> and<01:26:07.400> then<01:26:07.560> we<01:26:07.679> can 01:26:07.790 --> 01:26:07.800 align:start position:0% signature of get value and then we can 01:26:07.800 --> 01:26:11.189 align:start position:0% signature of get value and then we can do<01:26:08.000> the<01:26:08.159> same<01:26:08.440> thing<01:26:08.920> again<01:26:09.840> equal<01:26:10.800> and<01:26:11.000> if 01:26:11.189 --> 01:26:11.199 align:start position:0% do the same thing again equal and if 01:26:11.199 --> 01:26:14.229 align:start position:0% do the same thing again equal and if it's<01:26:11.480> equal<01:26:11.960> we<01:26:12.080> can<01:26:12.480> jump<01:26:12.800> to<01:26:13.119> the<01:26:13.360> get<01:26:14.080> uh 01:26:14.229 --> 01:26:14.239 align:start position:0% it's equal we can jump to the get uh 01:26:14.239 --> 01:26:17.550 align:start position:0% it's equal we can jump to the get uh macro<01:26:14.960> and<01:26:15.119> so<01:26:15.320> we<01:26:15.480> go<01:26:15.760> here<01:26:16.000> and<01:26:16.239> then<01:26:17.239> we 01:26:17.550 --> 01:26:17.560 align:start position:0% macro and so we go here and then we 01:26:17.560 --> 01:26:19.109 align:start position:0% macro and so we go here and then we execute<01:26:18.000> it 01:26:19.109 --> 01:26:19.119 align:start position:0% execute it 01:26:19.119 --> 01:26:25.510 align:start

maybe I can explain it like in a 01:26:36.400 --> 01:26:38.990 align:start position:0% maybe I can explain it like in a different<01:26:37.040> way<01:26:38.040> can<01:26:38.159> you<01:26:38.320> have<01:26:38.400> a<01:26:38.560> mic<01:26:38.800> over 01:26:38.990 --> 01:26:39.000 align:start position:0% different way can you have a mic over 01:26:39.000 --> 01:26:42.109 align:start position:0% different way can you have a mic over here 01:26:42.109 --> 01:26:42.119 align:start position:0% 01:26:42.119 --> 01:26:46.109 align:start position:0% please<01:26:43.119> thank<01:26:43.280> you<01:26:43.400> clo<01:26:44.280> um<01:26:44.800> so<01:26:45.239> dup<01:26:45.639> one<01:26:45.920> is 01:26:46.109 --> 01:26:46.119 align:start position:0% please thank you clo um so dup one is 01:26:46.119 --> 01:26:48.709 align:start position:0% please thank you clo um so dup one is that<01:26:46.400> duplicating<01:26:47.159> the<01:26:48.119> okay<01:26:48.440> it<01:26:48.560> is 01:26:48.709 --> 01:26:48.719 align:start position:0% that duplicating the okay it is 01:26:48.719 --> 01:26:51.510 align:start position:0% that duplicating the okay it is duplicating<01:26:49.239> the<01:26:49.400> stack<01:26:50.080> exactly<01:26:50.920> the<01:26:51.159> dup 01:26:51.510 --> 01:26:51.520 align:start position:0% duplicating the stack exactly the dup 01:26:51.520 --> 01:26:54.950 align:start position:0% duplicating the stack exactly the dup one<01:26:51.960> is<01:26:52.239> duplicating<01:26:53.040> the<01:26:53.199> first<01:26:53.880> item<01:26:54.560> of<01:26:54.760> the 01:26:54.950 --> 01:26:54.960 align:start position:0% one is duplicating the first item of the 01:26:54.960 --> 01:26:57.270 align:start position:0% one is duplicating the first item of the stack<01:26:55.560> on<01:26:55.679> the<01:26:55.840> stack<01:26:56.239> so<01:26:56.360> it's<01:26:56.560> duplicating 01:26:57.270 --> 01:26:57.280 align:start position:0% stack on the stack so it's duplicating 01:26:57.280 --> 01:27:00.070 align:start position:0% stack on the stack so it's duplicating the<01:26:57.679> call<01:26:58.320> uh<01:26:58.600> the<01:26:58.880> the<01:26:59.000> function<01:26:59.320> signature 01:27:00.070 --> 01:27:00.080 align:start position:0% the call uh the the function signature 01:27:00.080 --> 01:27:02.229 align:start position:0% the call uh the the function signature of<01:27:00.320> the<01:27:00.440> sender<01:27:00.960> yeah<01:27:01.119> so<01:27:01.239> it's<01:27:01.560> duplicating 01:27:02.229 --> 01:27:02.239 align:start position:0% of the sender yeah so it's duplicating 01:27:02.239 --> 01:27:04.750 align:start position:0% of the sender yeah so it's duplicating the<01:27:02.360> function<01:27:02.800> signature<01:27:03.440> that<01:27:03.600> we<01:27:04.040> received 01:27:04.750 --> 01:27:04.760 align:start position:0% the function signature that we received 01:27:04.760 --> 01:27:08.750 align:start position:0% the function signature that we received and<01:27:04.880> so<01:27:05.400> basically<01:27:06.400> the<01:27:06.800> D<01:27:07.159> one<01:27:07.560> here<01:27:08.400> uh<01:27:08.560> is 01:27:08.750 --> 01:27:08.760 align:start position:0% and so basically the D one here uh is 01:27:08.760 --> 01:27:11.990 align:start position:0% and so basically the D one here uh is just<01:27:08.960> a<01:27:09.119> way<01:27:09.320> for<01:27:09.560> us<01:27:09.719> to<01:27:10.080> avoid<01:27:10.719> doing<01:27:11.159> this 01:27:11.990 --> 01:27:12.000 align:start position:0% just a way for us to avoid doing this 01:27:12.000 --> 01:27:15.189 align:start position:0% just a way for us to avoid doing this again<01:27:12.840> because<01:27:13.199> we<01:27:13.320> could<01:27:13.480> be<01:27:13.719> doing<01:27:14.520> this<01:27:15.080> and 01:27:15.189 --> 01:27:15.199 align:start position:0% again because we could be doing this and 01:27:15.199 --> 01:27:18.070 align:start position:0% again because we could be doing this and then<01:27:15.360> we<01:27:15.480> do<01:27:15.760> this<01:27:16.320> we<01:27:16.440> don't<01:27:16.679> duplicate<01:27:17.639> but 01:27:18.070 --> 01:27:18.080 align:start position:0% then we do this we don't duplicate but 01:27:18.080 --> 01:27:21.550 align:start position:0% then we do this we don't duplicate but if<01:27:19.080> uh<01:27:19.280> it's<01:27:19.480> not<01:27:19.760> like<01:27:20.119> uh<01:27:20.639> if<01:27:20.840> the<01:27:20.960> standard 01:27:21.550 --> 01:27:21.560 align:start position:0% if uh it's not like uh if the standard 01:27:21.560 --> 01:27:24.550 align:start position:0% if uh it's not like uh if the standard is<01:27:21.719> not<01:27:22.280> willing<01:27:22.639> to<01:27:22.920> execute<01:27:23.360> that<01:27:23.679> value 01:27:24.550 --> 01:27:24.560 align:start position:0% is not willing to execute that value 01:27:24.560 --> 01:27:26.270 align:start position:0% is not willing to execute that value then<01:27:24.880> well<01:27:25.080> we<01:27:25.239> have<01:27:25.360> to<01:27:25.560> check<01:27:25.800> if<01:27:25.960> they<01:27:26.119> want 01:27:26.270 --> 01:27:26.280 align:start position:0% then well we have to check if they want 01:27:26.280 --> 01:27:28.750 align:start position:0% then well we have to check if they want to<01:27:26.480> execute<01:27:27.000> get<01:27:27.199> value<01:27:27.760> so<01:27:28.000> we<01:27:28.119> we<01:27:28.239> need<01:27:28.520> the 01:27:28.750 --> 01:27:28.760 align:start position:0% to execute get value so we we need the 01:27:28.760 --> 01:27:30.990 align:start position:0% to execute get value so we we need the function<01:27:29.199> signature<01:27:29.880> again<01:27:30.400> so<01:27:30.600> we<01:27:30.719> could<01:27:30.880> be 01:27:30.990 --> 01:27:31.000 align:start position:0% function signature again so we could be 01:27:31.000 --> 01:27:33.629 align:start position:0% function signature again so we could be doing<01:27:31.360> this<01:27:31.600> again<01:27:31.920> but<01:27:32.080> it<01:27:32.199> will<01:27:32.400> be<01:27:32.639> costly 01:27:33.629 --> 01:27:33.639 align:start position:0% doing this again but it will be costly 01:27:33.639 --> 01:27:36.109 align:start position:0% doing this again but it will be costly it<01:27:33.800> will<01:27:33.960> cost<01:27:34.760> so<01:27:34.880> then<01:27:35.400> don't<01:27:35.600> you<01:27:35.800> have<01:27:35.960> the 01:27:36.109 --> 01:27:36.119 align:start position:0% it will cost so then don't you have the 01:27:36.119 --> 01:27:38.149 align:start position:0% it will cost so then don't you have the function<01:27:36.520> signature<01:27:37.119> on<01:27:37.280> the<01:27:37.440> stack<01:27:37.880> three 01:27:38.149 --> 01:27:38.159 align:start position:0% function signature on the stack three 01:27:38.159 --> 01:27:40.870 align:start position:0% function signature on the stack three times<01:27:39.159> uh<01:27:39.440> because<01:27:39.639> you<01:27:39.760> call<01:27:40.000> duplicate<01:27:40.520> one 01:27:40.870 --> 01:27:40.880 align:start position:0% times uh because you call duplicate one 01:27:40.880 --> 01:27:44.590 align:start position:0% times uh because you call duplicate one twice<01:27:41.520> yeah<01:27:41.800> this<01:27:41.960> one<01:27:42.360> is<01:27:43.000> an<01:27:43.159> error<01:27:43.920> oh<01:27:44.119> okay 01:27:44.590 --> 01:27:44.600 align:start position:0% twice yeah this one is an error oh okay 01:27:44.600 --> 01:27:46.390 align:start position:0% twice yeah this one is an error oh okay I'm<01:27:44.719> sorry<01:27:45.000> about<01:27:45.280> that<01:27:45.800> this<01:27:45.920> one<01:27:46.080> is<01:27:46.199> an 01:27:46.390 --> 01:27:46.400 align:start position:0% I'm sorry about that this one is an 01:27:46.400 --> 01:27:49.350 align:start position:0% I'm sorry about that this one is an error<01:27:46.719> because<01:27:46.960> I<01:27:47.119> just<01:27:47.320> like<01:27:47.800> uh<01:27:48.600> copy<01:27:48.920> pasted 01:27:49.350 --> 01:27:49.360 align:start position:0% error because I just like uh copy pasted 01:27:49.360 --> 01:27:51.070 align:start position:0% error because I just like uh copy pasted that<01:27:49.560> that<01:27:49.880> line<01:27:50.119> and<01:27:50.280> then<01:27:50.480> I<01:27:50.600> change<01:27:50.800> this<01:27:51.040> I 01:27:51.070 --> 01:27:51.080 align:start position:0% that that line and then I change this I 01:27:51.080 --> 01:27:52.750 align:start position:0% that that line and then I change this I mean<01:27:51.199> there's<01:27:51.400> no<01:27:51.679> there's<01:27:51.880> no<01:27:52.119> harm<01:27:52.560> because 01:27:52.750 --> 01:27:52.760 align:start position:0% mean there's no there's no harm because 01:27:52.760 --> 01:27:55.669 align:start position:0% mean there's no there's no harm because you're<01:27:52.960> not<01:27:53.320> doing<01:27:53.639> anything<01:27:54.239> after<01:27:55.239> you<01:27:55.560> have 01:27:55.669 --> 01:27:55.679 align:start position:0% you're not doing anything after you have 01:27:55.679 --> 01:27:57.390 align:start position:0% you're not doing anything after you have the<01:27:55.800> function<01:27:56.159> signatures<01:27:56.920> this<01:27:57.040> could<01:27:57.239> be 01:27:57.390 --> 01:27:57.400 align:start position:0% the function signatures this could be 01:27:57.400 --> 01:27:59.669 align:start position:0% the function signatures this could be leading<01:27:57.719> to<01:27:57.920> some<01:27:58.199> issues<01:27:58.800> in<01:27:59.000> our<01:27:59.320> case<01:27:59.600> we 01:27:59.669 --> 01:27:59.679 align:start position:0% leading to some issues in our case we 01:27:59.679 --> 01:28:01.790 align:start position:0% leading to some issues in our case we are<01:27:59.880> just<01:28:00.080> reverting<01:28:00.719> right<01:28:00.960> after<01:28:01.520> so<01:28:01.679> it 01:28:01.790 --> 01:28:01.800 align:start position:0% are just reverting right after so it 01:28:01.800 --> 01:28:04.390 align:start position:0% are just reverting right after so it doesn't<01:28:02.199> matter<01:28:02.920> but<01:28:03.360> I<01:28:03.440> can<01:28:03.600> show<01:28:03.800> you<01:28:04.000> after 01:28:04.390 --> 01:28:04.400 align:start position:0% doesn't matter but I can show you after 01:28:04.400 --> 01:28:08.070 align:start position:0% doesn't matter but I can show you after like<01:28:05.040> for<01:28:05.280> example<01:28:05.719> in<01:28:05.840> the<01:28:06.000> case<01:28:06.199> of<01:28:06.719> erc20<01:28:07.719> or 01:28:08.070 --> 01:28:08.080 align:start position:0% like for example in the case of erc20 or 01:28:08.080 --> 01:28:10.709 align:start position:0% like for example in the case of erc20 or something<01:28:08.480> like<01:28:08.679> that<01:28:09.560> uh<01:28:09.800> but<01:28:10.000> yeah<01:28:10.400> you<01:28:10.480> can 01:28:10.709 --> 01:28:10.719 align:start position:0% something like that uh but yeah you can 01:28:10.719 --> 01:28:12.830 align:start position:0% something like that uh but yeah you can have<01:28:10.960> like<01:28:11.280> uh<01:28:11.719> many<01:28:12.080> different<01:28:12.400> things<01:28:12.639> so 01:28:12.830 --> 01:28:12.840 align:start position:0% have like uh many different things so 01:28:12.840 --> 01:28:15.590 align:start position:0% have like uh many different things so you<01:28:12.960> will<01:28:13.199> duplicate<01:28:14.119> every<01:28:14.400> time<01:28:14.960> but<01:28:15.199> on<01:28:15.400> the 01:28:15.590 --> 01:28:15.600 align:start position:0% you will duplicate every time but on the 01:28:15.600 --> 01:28:18.669 align:start position:0% you will duplicate every time but on the last<01:28:16.360> time<01:28:16.719> it's<01:28:16.920> not<01:28:17.159> needed<01:28:17.800> you're<01:28:18.000> right 01:28:18.669 --> 01:28:18.679 align:start position:0% last time it's not needed you're right 01:28:18.679 --> 01:28:21.669 align:start position:0% last time it's not needed you're right okay<01:28:18.920> all<01:28:19.040> right<01:28:19.199> that<01:28:19.320> makes<01:28:19.520> sense<01:28:19.800> so<01:28:20.800> um 01:28:21.669 --> 01:28:21.679 align:start position:0% okay all right that makes sense so um 01:28:21.679 --> 01:28:24.870 align:start position:0% okay all right that makes sense so um question<01:28:22.679> so<01:28:22.920> when<01:28:23.080> you<01:28:23.280> do<01:28:23.520> the<01:28:23.719> equal 01:28:24.870 --> 01:28:24.880 align:start position:0% question so when you do the equal 01:28:24.880 --> 01:28:27.189 align:start position:0% question so when you do the equal it's<01:28:25.280> actually<01:28:25.639> taking<01:28:26.040> two<01:28:26.400> values<01:28:26.960> that's 01:28:27.189 --> 01:28:27.199 align:start position:0% it's actually taking two values that's 01:28:27.199 --> 01:28:29.629 align:start position:0% it's actually taking two values that's on<01:28:27.400> the<01:28:27.679> stack<01:28:28.400> well<01:28:28.679> no<01:28:28.960> well<01:28:29.159> taking<01:28:29.440> one 01:28:29.629 --> 01:28:29.639 align:start position:0% on the stack well no well taking one 01:28:29.639 --> 01:28:31.109 align:start position:0% on the stack well no well taking one value<01:28:29.920> that's<01:28:30.080> already<01:28:30.320> on<01:28:30.400> the<01:28:30.560> stack<01:28:30.960> and 01:28:31.109 --> 01:28:31.119 align:start position:0% value that's already on the stack and 01:28:31.119 --> 01:28:32.270 align:start position:0% value that's already on the stack and the<01:28:31.239> other<01:28:31.440> value<01:28:31.679> is<01:28:31.800> the<01:28:31.880> one<01:28:32.080> that's 01:28:32.270 --> 01:28:32.280 align:start position:0% the other value is the one that's 01:28:32.280 --> 01:28:35.709 align:start position:0% the other value is the one that's computed<01:28:33.199> uh<01:28:33.360> as<01:28:33.520> part<01:28:33.639> of<01:28:33.800> that<01:28:34.119> call<01:28:34.920> uh<01:28:35.520> it's 01:28:35.709 --> 01:28:35.719 align:start position:0% computed uh as part of that call uh it's 01:28:35.719 --> 01:28:37.910 align:start position:0% computed uh as part of that call uh it's taking<01:28:36.239> like<01:28:36.440> when<01:28:36.600> you're<01:28:36.880> doing<01:28:37.560> uh<01:28:37.760> yeah 01:28:37.910 --> 01:28:37.920 align:start position:0% taking like when you're doing uh yeah 01:28:37.920 --> 01:28:40.950 align:start position:0% taking like when you're doing uh yeah equal<01:28:38.280> is<01:28:38.440> going<01:28:38.639> to<01:28:38.840> take<01:28:39.040> so<01:28:39.920> uh<01:28:40.239> this<01:28:40.600> so<01:28:40.840> we 01:28:40.950 --> 01:28:40.960 align:start position:0% equal is going to take so uh this so we 01:28:40.960 --> 01:28:42.430 align:start position:0% equal is going to take so uh this so we have<01:28:41.159> this<01:28:41.360> value<01:28:41.679> in<01:28:41.800> the<01:28:42.000> stack<01:28:42.320> right 01:28:42.430 --> 01:28:42.440 align:start position:0% have this value in the stack right 01:28:42.440 --> 01:28:44.310 align:start position:0% have this value in the stack right that's<01:28:42.600> on<01:28:42.760> the<01:28:42.960> stack<01:28:43.520> and<01:28:43.639> then<01:28:43.840> so<01:28:44.000> you<01:28:44.119> can 01:28:44.310 --> 01:28:44.320 align:start position:0% that's on the stack and then so you can 01:28:44.320 --> 01:28:47.189 align:start position:0% that's on the stack and then so you can imagine<01:28:44.840> that<01:28:45.679> here<01:28:46.080> we<01:28:46.280> duplicate<01:28:46.880> so<01:28:47.080> this 01:28:47.189 --> 01:28:47.199 align:start position:0% imagine that here we duplicate so this 01:28:47.199 --> 01:28:50.470 align:start position:0% imagine that here we duplicate so this means<01:28:47.520> that<01:28:47.880> this<01:28:48.199> value<01:28:48.960> is<01:28:49.600> here<01:28:49.960> it's<01:28:50.280> like 01:28:50.470 --> 01:28:50.480 align:start position:0% means that this value is here it's like 01:28:50.480 --> 01:28:51.750 align:start position:0% means that this value is here it's like we<01:28:50.560> are<01:28:50.719> cloning 01:28:51.750 --> 01:28:51.760 align:start position:0% we are cloning 01:28:51.760 --> 01:28:53.550 align:start position:0% we are cloning it<01:28:52.760> if<01:28:52.840> you<01:28:52.880> don't<01:28:53.040> mind<01:28:53.199> I'm<01:28:53.320> just<01:28:53.400> going<01:28:53.480> to 01:28:53.550 --> 01:28:53.560 align:start position:0% it if you don't mind I'm just going to 01:28:53.560 --> 01:28:55.510 align:start position:0% it if you don't mind I'm just going to interrupt<01:28:53.840> you<01:28:54.320> quick<01:28:54.520> because<01:28:55.040> the<01:28:55.199> question 01:28:55.510 --> 01:28:55.520 align:start position:0% interrupt you quick because the question 01:28:55.520 --> 01:28:58.350 align:start position:0% interrupt you quick because the question I<01:28:55.760> have<01:28:56.159> is<01:28:56.920> the<01:28:57.119> function<01:28:57.719> signature<01:28:58.239> that 01:28:58.350 --> 01:28:58.360 align:start position:0% I have is the function signature that 01:28:58.360 --> 01:29:01.310 align:start position:0% I have is the function signature that looks<01:28:58.560> like<01:28:58.679> a<01:28:58.920> macro<01:28:59.920> is<01:29:00.159> that<01:29:00.480> putting<01:29:01.040> the 01:29:01.310 --> 01:29:01.320 align:start position:0% looks like a macro is that putting the 01:29:01.320 --> 01:29:03.910 align:start position:0% looks like a macro is that putting the value<01:29:01.880> of<01:29:02.119> that<01:29:02.719> it's<01:29:02.920> Computing<01:29:03.560> the<01:29:03.800> the 01:29:03.910 --> 01:29:03.920 align:start position:0% value of that it's Computing the the 01:29:03.920 --> 01:29:06.709 align:start position:0% value of that it's Computing the the function<01:29:04.320> signature<01:29:04.960> of<01:29:05.440> get<01:29:05.719> value<01:29:06.239> right 01:29:06.709 --> 01:29:06.719 align:start position:0% function signature of get value right 01:29:06.719 --> 01:29:08.750 align:start position:0% function signature of get value right and<01:29:06.840> is<01:29:06.960> it<01:29:07.159> putting<01:29:07.400> it<01:29:07.520> on<01:29:07.639> the<01:29:07.840> stack<01:29:08.480> and 01:29:08.750 --> 01:29:08.760 align:start position:0% and is it putting it on the stack and 01:29:08.760 --> 01:29:11.270 align:start position:0% and is it putting it on the stack and then<01:29:09.080> the<01:29:09.239> equal<01:29:09.920> equal<01:29:10.320> function<01:29:10.800> is 01:29:11.270 --> 01:29:11.280 align:start position:0% then the equal equal function is 01:29:11.280 --> 01:29:13.350 align:start position:0% then the equal equal function is Computing<01:29:12.199> the<01:29:12.360> equal<01:29:12.679> between<01:29:13.000> those<01:29:13.159> two 01:29:13.350 --> 01:29:13.360 align:start position:0% Computing the equal between those two 01:29:13.360 --> 01:29:15.350 align:start position:0% Computing the equal between those two values<01:29:13.639> that<01:29:13.760> are<01:29:13.840> on<01:29:14.000> the<01:29:14.159> stack<01:29:14.960> okay<01:29:15.199> thank 01:29:15.350 --> 01:29:15.360 align:start position:0% values that are on the stack okay thank 01:29:15.360 --> 01:29:17.270 align:start position:0% values that are on the stack okay thank you<01:29:15.639> yeah<01:29:15.800> because<01:29:16.119> so<01:29:16.400> this<01:29:16.520> is<01:29:16.719> exactly<01:29:17.159> what 01:29:17.270 --> 01:29:17.280 align:start position:0% you yeah because so this is exactly what 01:29:17.280 --> 01:29:19.950 align:start position:0% you yeah because so this is exactly what you<01:29:17.400> said<01:29:17.800> here<01:29:18.159> equal<01:29:18.520> is<01:29:18.679> going<01:29:18.840> to<01:29:19.080> take<01:29:19.760> the 01:29:19.950 --> 01:29:19.960 align:start position:0% you said here equal is going to take the 01:29:19.960 --> 01:29:21.990 align:start position:0% you said here equal is going to take the first<01:29:20.280> element<01:29:20.639> of<01:29:20.800> the<01:29:21.040> stack<01:29:21.719> and<01:29:21.840> the 01:29:21.990 --> 01:29:22.000 align:start position:0% first element of the stack and the 01:29:22.000 --> 01:29:24.790 align:start position:0% first element of the stack and the second<01:29:22.440> element<01:29:22.760> of<01:29:22.920> the<01:29:23.119> stack<01:29:23.719> so 01:29:24.790 --> 01:29:24.800 align:start position:0% second element of the stack so 01:29:24.800 --> 01:29:28.390 align:start position:0% second element of the stack so that<01:29:25.000> was<01:29:26.000> duplicated<01:29:26.880> from<01:29:27.199> this<01:29:27.800> so<01:29:28.000> we<01:29:28.159> have 01:29:28.390 --> 01:29:28.400 align:start position:0% that was duplicated from this so we have 01:29:28.400 --> 01:29:32.350 align:start position:0% that was duplicated from this so we have like<01:29:28.880> uh<01:29:29.880> here<01:29:30.239> our<01:29:30.600> stuff<01:29:31.119> that<01:29:31.239> was<01:29:31.480> computed 01:29:32.350 --> 01:29:32.360 align:start position:0% like uh here our stuff that was computed 01:29:32.360 --> 01:29:33.950 align:start position:0% like uh here our stuff that was computed and<01:29:32.520> add<01:29:32.719> it<01:29:32.840> to<01:29:32.960> the<01:29:33.119> stack<01:29:33.480> and<01:29:33.639> then<01:29:33.840> the 01:29:33.950 --> 01:29:33.960 align:start position:0% and add it to the stack and then the 01:29:33.960 --> 01:29:35.950 align:start position:0% and add it to the stack and then the stuff<01:29:34.239> we<01:29:34.400> just<01:29:34.560> computed<01:29:35.040> ourself<01:29:35.600> perfect 01:29:35.950 --> 01:29:35.960 align:start position:0% stuff we just computed ourself perfect 01:29:35.960 --> 01:29:37.470 align:start position:0% stuff we just computed ourself perfect thank 01:29:37.470 --> 01:29:37.480 align:start position:0% thank 01:29:37.480 --> 01:29:41.109 align:start position:0% thank you<01:29:38.480> uh<01:29:38.880> yeah<01:29:39.040> and<01:29:39.199> then<01:29:39.440> it's<01:29:40.119> kind<01:29:40.280> of<01:29:40.560> simple 01:29:41.109 --> 01:29:41.119 align:start position:0% you uh yeah and then it's kind of simple 01:29:41.119 --> 01:29:45.510 align:start position:0% you uh yeah and then it's kind of simple here<01:29:41.880> like<01:29:42.440> uh<01:29:42.719> to<01:29:43.360> set<01:29:43.679> the<01:29:43.920> value<01:29:44.840> well<01:29:45.239> we 01:29:45.510 --> 01:29:45.520 align:start position:0% here like uh to set the value well we 01:29:45.520 --> 01:29:48.870 align:start position:0% here like uh to set the value well we just<01:29:45.679> go<01:29:45.880> to<01:29:46.040> the<01:29:46.199> macro<01:29:46.679> here<01:29:46.880> set<01:29:47.400> value<01:29:48.400> and 01:29:48.870 --> 01:29:48.880 align:start position:0% just go to the macro here set value and 01:29:48.880 --> 01:29:50.870 align:start position:0% just go to the macro here set value and well<01:29:49.560> this<01:29:49.639> is<01:29:49.920> exactly<01:29:50.320> what<01:29:50.480> we've<01:29:50.679> been 01:29:50.870 --> 01:29:50.880 align:start position:0% well this is exactly what we've been 01:29:50.880 --> 01:29:54.030 align:start position:0% well this is exactly what we've been doing<01:29:51.239> earlier<01:29:52.080> we<01:29:52.239> know<01:29:52.560> that<01:29:53.239> uh<01:29:53.360> we<01:29:53.480> need<01:29:53.600> to 01:29:54.030 --> 01:29:54.040 align:start position:0% doing earlier we know that uh we need to 01:29:54.040 --> 01:29:56.870 align:start position:0% doing earlier we know that uh we need to avoid<01:29:54.360> the<01:29:54.480> first<01:29:55.480> uh<01:29:55.639> four<01:29:56.199> bytes<01:29:56.600> because 01:29:56.870 --> 01:29:56.880 align:start position:0% avoid the first uh four bytes because 01:29:56.880 --> 01:29:58.550 align:start position:0% avoid the first uh four bytes because this<01:29:57.000> is<01:29:57.119> the<01:29:57.280> function<01:29:57.760> signature<01:29:58.280> so<01:29:58.440> we 01:29:58.550 --> 01:29:58.560 align:start position:0% this is the function signature so we 01:29:58.560 --> 01:30:00.990 align:start position:0% this is the function signature so we don't<01:29:58.760> really<01:29:58.960> care<01:29:59.199> about<01:29:59.440> it<01:30:00.080> so<01:30:00.400> we<01:30:00.520> just<01:30:00.679> do 01:30:00.990 --> 01:30:01.000 align:start position:0% don't really care about it so we just do 01:30:01.000 --> 01:30:04.270 align:start position:0% don't really care about it so we just do okay<01:30:01.159> we<01:30:01.280> want<01:30:01.400> to<01:30:01.800> load<01:30:02.800> uh<01:30:03.000> 32<01:30:03.520> bytes 01:30:04.270 --> 01:30:04.280 align:start position:0% okay we want to load uh 32 bytes 01:30:04.280 --> 01:30:07.870 align:start position:0% okay we want to load uh 32 bytes starting<01:30:04.920> after<01:30:05.320> the<01:30:05.480> four<01:30:06.199> uh<01:30:06.400> bytes<01:30:07.400> and 01:30:07.870 --> 01:30:07.880 align:start position:0% starting after the four uh bytes and 01:30:07.880 --> 01:30:10.310 align:start position:0% starting after the four uh bytes and then<01:30:08.119> we<01:30:08.239> are<01:30:08.400> going<01:30:08.600> to<01:30:08.719> use<01:30:09.000> a<01:30:09.280> different<01:30:10.040> up 01:30:10.310 --> 01:30:10.320 align:start position:0% then we are going to use a different up 01:30:10.320 --> 01:30:13.950 align:start position:0% then we are going to use a different up code<01:30:10.600> that<01:30:10.719> we<01:30:10.880> never<01:30:11.159> used<01:30:11.560> called<01:30:12.400> s<01:30:13.080> store 01:30:13.950 --> 01:30:13.960 align:start position:0% code that we never used called s store 01:30:13.960 --> 01:30:16.629 align:start position:0% code that we never used called s store so<01:30:14.360> you<01:30:14.480> can<01:30:14.639> see<01:30:14.880> like<01:30:15.400> previously<01:30:16.400> we've 01:30:16.629 --> 01:30:16.639 align:start position:0% so you can see like previously we've 01:30:16.639 --> 01:30:20.310 align:start position:0% so you can see like previously we've been<01:30:16.960> using<01:30:17.440> M<01:30:17.760> store<01:30:18.239> which<01:30:18.400> is<01:30:19.119> very<01:30:20.119> well 01:30:20.310 --> 01:30:20.320 align:start position:0% been using M store which is very well 01:30:20.320 --> 01:30:23.350 align:start position:0% been using M store which is very well explicit<01:30:21.040> memory<01:30:21.560> store<01:30:22.480> and<01:30:22.679> in<01:30:22.880> this<01:30:23.080> case 01:30:23.350 --> 01:30:23.360 align:start position:0% explicit memory store and in this case 01:30:23.360 --> 01:30:25.709 align:start position:0% explicit memory store and in this case we<01:30:23.480> want<01:30:23.600> to<01:30:23.719> store<01:30:24.400> in<01:30:24.560> the<01:30:24.760> storage<01:30:25.360> because 01:30:25.709 --> 01:30:25.719 align:start position:0% we want to store in the storage because 01:30:25.719 --> 01:30:27.510 align:start position:0% we want to store in the storage because the<01:30:25.840> user<01:30:26.159> is<01:30:26.280> setting<01:30:26.600> a<01:30:26.800> value<01:30:27.119> so<01:30:27.280> we<01:30:27.360> want 01:30:27.510 --> 01:30:27.520 align:start position:0% the user is setting a value so we want 01:30:27.520 --> 01:30:31.590 align:start position:0% the user is setting a value so we want to<01:30:27.719> keep<01:30:27.920> it<01:30:28.440> for<01:30:29.119> a<01:30:29.320> long<01:30:29.760> time<01:30:30.760> so<01:30:31.159> we<01:30:31.320> are 01:30:31.590 --> 01:30:31.600 align:start position:0% to keep it for a long time so we are 01:30:31.600 --> 01:30:34.669 align:start position:0% to keep it for a long time so we are going<01:30:31.840> to<01:30:32.080> call<01:30:32.280> s<01:30:32.520> store<01:30:33.159> and<01:30:33.360> s<01:30:33.639> store<01:30:34.119> Works 01:30:34.669 --> 01:30:34.679 align:start position:0% going to call s store and s store Works 01:30:34.679 --> 01:30:38.189 align:start position:0% going to call s store and s store Works in<01:30:34.800> a<01:30:35.520> very<01:30:36.199> similar<01:30:36.639> way<01:30:36.840> to<01:30:37.080> M<01:30:37.320> store<01:30:38.040> it 01:30:38.189 --> 01:30:38.199 align:start position:0% in a very similar way to M store it 01:30:38.199 --> 01:30:42.669 align:start position:0% in a very similar way to M store it takes<01:30:38.639> like<01:30:39.000> one<01:30:39.760> um<01:30:40.360> location<01:30:41.199> and<01:30:41.400> one<01:30:41.719> value 01:30:42.669 --> 01:30:42.679 align:start position:0% takes like one um location and one value 01:30:42.679 --> 01:30:45.070 align:start position:0% takes like one um location and one value and<01:30:42.880> so<01:30:43.480> what<01:30:43.639> we<01:30:43.800> are<01:30:44.000> doing<01:30:44.400> here<01:30:44.639> in<01:30:44.880> this 01:30:45.070 --> 01:30:45.080 align:start position:0% and so what we are doing here in this 01:30:45.080 --> 01:30:47.790 align:start position:0% and so what we are doing here in this case<01:30:45.440> I<01:30:45.560> showed<01:30:45.880> you<01:30:46.159> this<01:30:46.760> earlier<01:30:47.480> when<01:30:47.639> we 01:30:47.790 --> 01:30:47.800 align:start position:0% case I showed you this earlier when we 01:30:47.800 --> 01:30:50.030 align:start position:0% case I showed you this earlier when we talked<01:30:48.159> about<01:30:48.440> constants<01:30:49.360> we<01:30:49.480> are<01:30:49.639> just<01:30:49.880> going 01:30:50.030 --> 01:30:50.040 align:start position:0% talked about constants we are just going 01:30:50.040 --> 01:30:53.510 align:start position:0% talked about constants we are just going to<01:30:50.199> use<01:30:50.480> like<01:30:50.840> uh<01:30:51.400> within<01:30:52.000> brackets<01:30:53.000> we<01:30:53.159> are 01:30:53.510 --> 01:30:53.520 align:start position:0% to use like uh within brackets we are 01:30:53.520 --> 01:30:57.470 align:start position:0% to use like uh within brackets we are going<01:30:54.119> to<01:30:54.639> call<01:30:55.560> Value<01:30:56.040> location<01:30:57.040> which<01:30:57.239> was 01:30:57.470 --> 01:30:57.480 align:start position:0% going to call Value location which was 01:30:57.480 --> 01:31:00.790 align:start position:0% going to call Value location which was defined<01:30:57.920> by<01:30:58.119> free<01:30:58.480> storage<01:30:59.040> pointer<01:31:00.000> which 01:31:00.790 --> 01:31:00.800 align:start position:0% defined by free storage pointer which 01:31:00.800 --> 01:31:03.590 align:start position:0% defined by free storage pointer which should<01:31:01.040> be<01:31:01.520> zero<01:31:02.520> so<01:31:02.760> this<01:31:02.880> means<01:31:03.239> that<01:31:03.480> we 01:31:03.590 --> 01:31:03.600 align:start position:0% should be zero so this means that we 01:31:03.600 --> 01:31:08.270 align:start position:0% should be zero so this means that we want<01:31:04.280> to<01:31:05.280> St<01:31:05.679> store<01:31:06.159> in<01:31:06.320> the<01:31:06.679> storage<01:31:07.679> at<01:31:08.000> this 01:31:08.270 --> 01:31:08.280 align:start position:0% want to St store in the storage at this 01:31:08.280 --> 01:31:10.910 align:start position:0% want to St store in the storage at this location<01:31:09.280> the<01:31:09.520> value<01:31:10.000> that<01:31:10.159> is<01:31:10.320> starting<01:31:10.760> at 01:31:10.910 --> 01:31:10.920 align:start position:0% location the value that is starting at 01:31:10.920 --> 01:31:14.910 align:start position:0% location the value that is starting at the<01:31:11.080> cold<01:31:11.360> data<01:31:12.159> after<01:31:12.520> the<01:31:12.679> first<01:31:13.199> four<01:31:13.920> bytes 01:31:14.910 --> 01:31:14.920 align:start position:0% the cold data after the first four bytes 01:31:14.920 --> 01:31:17.629 align:start position:0% the cold data after the first four bytes so<01:31:15.239> kind<01:31:15.400> of<01:31:15.639> simple<01:31:16.280> it's<01:31:16.480> just<01:31:16.719> weird<01:31:17.119> that<01:31:17.560> I 01:31:17.629 --> 01:31:17.639 align:start position:0% so kind of simple it's just weird that I 01:31:17.639 --> 01:31:19.430 align:start position:0% so kind of simple it's just weird that I think<01:31:17.840> the<01:31:18.040> weirdest<01:31:18.560> thing<01:31:18.840> here<01:31:19.159> that<01:31:19.320> you 01:31:19.430 --> 01:31:19.440 align:start position:0% think the weirdest thing here that you 01:31:19.440 --> 01:31:21.830 align:start position:0% think the weirdest thing here that you are<01:31:19.600> just<01:31:19.760> doing<01:31:20.119> things<01:31:20.480> in<01:31:20.679> Reverse<01:31:21.639> you 01:31:21.830 --> 01:31:21.840 align:start position:0% are just doing things in Reverse you 01:31:21.840 --> 01:31:24.430 align:start position:0% are just doing things in Reverse you have<01:31:21.960> to<01:31:22.199> put<01:31:22.600> element<01:31:23.040> in<01:31:23.199> the<01:31:23.400> stack<01:31:24.239> and 01:31:24.430 --> 01:31:24.440 align:start position:0% have to put element in the stack and 01:31:24.440 --> 01:31:25.910 align:start position:0% have to put element in the stack and then<01:31:24.560> you<01:31:24.719> have<01:31:24.840> to<01:31:25.000> call<01:31:25.199> a<01:31:25.360> function<01:31:25.800> that 01:31:25.910 --> 01:31:25.920 align:start position:0% then you have to call a function that 01:31:25.920 --> 01:31:29.350 align:start position:0% then you have to call a function that will<01:31:26.119> take<01:31:26.480> all<01:31:26.679> the<01:31:27.159> elements<01:31:28.159> uh<01:31:28.600> in<01:31:28.840> the 01:31:29.350 --> 01:31:29.360 align:start position:0% will take all the elements uh in the 01:31:29.360 --> 01:31:31.870 align:start position:0% will take all the elements uh in the opposite<01:31:29.880> direction<01:31:30.280> so<01:31:30.520> it's<01:31:30.639> a<01:31:30.800> bit<01:31:31.080> weird 01:31:31.870 --> 01:31:31.880 align:start position:0% opposite direction so it's a bit weird 01:31:31.880 --> 01:31:35.629 align:start position:0% opposite direction so it's a bit weird to<01:31:32.320> think<01:31:32.679> that<01:31:32.880> way<01:31:33.119> but<01:31:33.280> you<01:31:33.480> get<01:31:33.760> used<01:31:34.040> to<01:31:34.639> it 01:31:35.629 --> 01:31:35.639 align:start position:0% to think that way but you get used to it 01:31:35.639 --> 01:31:38.149 align:start position:0% to think that way but you get used to it and<01:31:36.280> yeah<01:31:36.480> like<01:31:37.000> you<01:31:37.159> mention<01:31:37.679> like<01:31:37.880> many 01:31:38.149 --> 01:31:38.159 align:start position:0% and yeah like you mention like many 01:31:38.159 --> 01:31:40.790 align:start position:0% and yeah like you mention like many times<01:31:38.480> like<01:31:38.719> the<01:31:38.880> the<01:31:39.040> stack<01:31:39.400> how<01:31:39.520> it<01:31:39.679> works<01:31:40.679> uh 01:31:40.790 --> 01:31:40.800 align:start position:0% times like the the stack how it works uh 01:31:40.800 --> 01:31:43.790 align:start position:0% times like the the stack how it works uh and<01:31:40.960> so<01:31:41.520> like<01:31:41.760> a<01:31:41.960> convention<01:31:42.560> some<01:31:42.840> people<01:31:43.520> are 01:31:43.790 --> 01:31:43.800 align:start position:0% and so like a convention some people are 01:31:43.800 --> 01:31:45.669 align:start position:0% and so like a convention some people are doing<01:31:44.360> and<01:31:44.560> actually<01:31:44.840> I<01:31:44.960> think<01:31:45.199> there's<01:31:45.520> a 01:31:45.669 --> 01:31:45.679 align:start position:0% doing and actually I think there's a 01:31:45.679 --> 01:31:48.790 align:start position:0% doing and actually I think there's a tool<01:31:45.960> for<01:31:46.199> that<01:31:46.960> uh<01:31:47.080> some<01:31:47.400> people<01:31:48.080> here<01:31:48.440> like 01:31:48.790 --> 01:31:48.800 align:start position:0% tool for that uh some people here like 01:31:48.800 --> 01:31:51.870 align:start position:0% tool for that uh some people here like uh<01:31:49.239> add<01:31:49.600> comments<01:31:50.520> and<01:31:50.840> within<01:31:51.119> the<01:31:51.280> brackets 01:31:51.870 --> 01:31:51.880 align:start position:0% uh add comments and within the brackets 01:31:51.880 --> 01:31:54.790 align:start position:0% uh add comments and within the brackets they<01:31:52.239> just<01:31:52.679> put<01:31:53.199> what<01:31:53.360> is<01:31:53.520> in<01:31:53.639> the<01:31:54.000> stack<01:31:54.520> so 01:31:54.790 --> 01:31:54.800 align:start position:0% they just put what is in the stack so 01:31:54.800 --> 01:31:57.790 align:start position:0% they just put what is in the stack so they<01:31:54.920> will<01:31:55.080> say<01:31:55.480> okay<01:31:55.800> here<01:31:56.719> we<01:31:56.920> have<01:31:57.159> a<01:31:57.400> value 01:31:57.790 --> 01:31:57.800 align:start position:0% they will say okay here we have a value 01:31:57.800 --> 01:32:00.750 align:start position:0% they will say okay here we have a value here<01:31:58.520> so<01:31:58.880> because<01:31:59.119> we<01:31:59.280> loaded<01:31:59.719> this<01:31:59.920> value<01:32:00.600> and 01:32:00.750 --> 01:32:00.760 align:start position:0% here so because we loaded this value and 01:32:00.760 --> 01:32:03.149 align:start position:0% here so because we loaded this value and then<01:32:00.920> they<01:32:01.040> say<01:32:01.280> we<01:32:01.400> have<01:32:01.560> a<01:32:01.880> pointer<01:32:02.440> here<01:32:02.960> so 01:32:03.149 --> 01:32:03.159 align:start position:0% then they say we have a pointer here so 01:32:03.159 --> 01:32:05.070 align:start position:0% then they say we have a pointer here so the<01:32:03.320> stack<01:32:03.600> is<01:32:03.760> like<01:32:03.960> the<01:32:04.119> pointer<01:32:04.639> and<01:32:04.880> the 01:32:05.070 --> 01:32:05.080 align:start position:0% the stack is like the pointer and the 01:32:05.080 --> 01:32:07.109 align:start position:0% the stack is like the pointer and the value<01:32:05.800> and<01:32:06.040> they<01:32:06.239> they<01:32:06.400> say<01:32:06.679> okay<01:32:06.840> we<01:32:06.960> are 01:32:07.109 --> 01:32:07.119 align:start position:0% value and they they say okay we are 01:32:07.119 --> 01:32:10.950 align:start position:0% value and they they say okay we are calling<01:32:08.119> uh<01:32:08.719> storage<01:32:09.560> uh<01:32:09.679> store<01:32:10.480> so<01:32:10.800> it's 01:32:10.950 --> 01:32:10.960 align:start position:0% calling uh storage uh store so it's 01:32:10.960 --> 01:32:12.790 align:start position:0% calling uh storage uh store so it's going<01:32:11.199> to<01:32:11.320> use<01:32:11.560> two<01:32:11.800> values<01:32:12.199> so<01:32:12.520> then<01:32:12.679> the 01:32:12.790 --> 01:32:12.800 align:start position:0% going to use two values so then the 01:32:12.800 --> 01:32:15.430 align:start position:0% going to use two values so then the stack<01:32:13.119> is<01:32:13.239> empty<01:32:13.920> so<01:32:14.080> it's<01:32:14.320> like<01:32:14.600> also<01:32:14.960> a<01:32:15.159> nice 01:32:15.430 --> 01:32:15.440 align:start position:0% stack is empty so it's like also a nice 01:32:15.440 --> 01:32:17.470 align:start position:0% stack is empty so it's like also a nice way<01:32:15.639> to<01:32:15.800> be<01:32:15.960> able<01:32:16.159> to<01:32:16.360> track<01:32:16.800> what<01:32:16.920> you're 01:32:17.470 --> 01:32:17.480 align:start position:0% way to be able to track what you're 01:32:17.480 --> 01:32:18.750 align:start position:0% way to be able to track what you're actually 01:32:18.750 --> 01:32:18.760 align:start position:0% actually 01:32:18.760 --> 01:32:24.709 align:start position:0% actually doing<01:32:19.960> question<01:32:20.960> yep<01:32:21.719> so<01:32:22.560> um<01:32:22.840> on<01:32:23.040> the<01:32:23.239> stack<01:32:24.000> if 01:32:24.709 --> 01:32:24.719 align:start position:0% doing question yep so um on the stack if 01:32:24.719 --> 01:32:26.470 align:start position:0% doing question yep so um on the stack if what<01:32:24.840> is<01:32:25.000> the<01:32:25.159> first<01:32:25.440> argument<01:32:25.960> is<01:32:26.040> it<01:32:26.199> the<01:32:26.320> one 01:32:26.470 --> 01:32:26.480 align:start position:0% what is the first argument is it the one 01:32:26.480 --> 01:32:28.350 align:start position:0% what is the first argument is it the one at<01:32:26.639> the<01:32:26.840> topmost<01:32:27.639> and<01:32:27.760> then<01:32:27.880> the<01:32:28.040> second 01:32:28.350 --> 01:32:28.360 align:start position:0% at the topmost and then the second 01:32:28.360 --> 01:32:30.550 align:start position:0% at the topmost and then the second argument<01:32:28.679> is<01:32:28.760> the<01:32:28.880> one<01:32:29.040> below<01:32:29.320> it<01:32:29.880> yes<01:32:30.360> so<01:32:30.480> when 01:32:30.550 --> 01:32:30.560 align:start position:0% argument is the one below it yes so when 01:32:30.560 --> 01:32:32.070 align:start position:0% argument is the one below it yes so when you're<01:32:30.760> calling<01:32:31.040> a<01:32:31.199> function<01:32:31.520> it<01:32:31.639> will<01:32:31.880> take 01:32:32.070 --> 01:32:32.080 align:start position:0% you're calling a function it will take 01:32:32.080 --> 01:32:33.990 align:start position:0% you're calling a function it will take like<01:32:32.239> the<01:32:32.440> one<01:32:32.639> at<01:32:32.800> the<01:32:33.000> top<01:32:33.280> and<01:32:33.400> it<01:32:33.520> will<01:32:33.760> go 01:32:33.990 --> 01:32:34.000 align:start position:0% like the one at the top and it will go 01:32:34.000 --> 01:32:36.629 align:start position:0% like the one at the top and it will go like<01:32:34.520> it<01:32:34.639> will<01:32:34.840> remove<01:32:35.239> them<01:32:35.520> one<01:32:35.760> by<01:32:35.960> one<01:32:36.440> so 01:32:36.629 --> 01:32:36.639 align:start position:0% like it will remove them one by one so 01:32:36.639 --> 01:32:39.070 align:start position:0% like it will remove them one by one so it<01:32:36.719> will<01:32:37.159> always<01:32:37.480> take<01:32:37.760> what<01:32:37.920> is<01:32:38.080> on<01:32:38.360> top<01:32:38.960> okay 01:32:39.070 --> 01:32:39.080 align:start position:0% it will always take what is on top okay 01:32:39.080 --> 01:32:41.070 align:start position:0% it will always take what is on top okay so<01:32:39.239> the<01:32:39.400> topest<01:32:39.800> one<01:32:40.040> is<01:32:40.159> the<01:32:40.320> first<01:32:40.639> argument 01:32:41.070 --> 01:32:41.080 align:start position:0% so the topest one is the first argument 01:32:41.080 --> 01:32:43.430 align:start position:0% so the topest one is the first argument in<01:32:41.239> the<01:32:41.400> function<01:32:41.840> signature<01:32:42.560> and<01:32:42.719> then<01:32:42.920> the 01:32:43.430 --> 01:32:43.440 align:start position:0% in the function signature and then the 01:32:43.440 --> 01:32:45.550 align:start position:0% in the function signature and then the second<01:32:44.400> yeah<01:32:44.520> in<01:32:44.639> this<01:32:44.800> case<01:32:45.000> yeah<01:32:45.199> would 01:32:45.550 --> 01:32:45.560 align:start position:0% second yeah in this case yeah would 01:32:45.560 --> 01:32:47.669 align:start position:0% second yeah in this case yeah would first<01:32:45.800> use<01:32:46.159> like<01:32:46.280> the<01:32:46.400> function<01:32:46.800> signature<01:32:47.520> so 01:32:47.669 --> 01:32:47.679 align:start position:0% first use like the function signature so 01:32:47.679 --> 01:32:49.790 align:start position:0% first use like the function signature so if<01:32:47.760> you<01:32:47.920> are<01:32:48.040> doing<01:32:48.360> like<01:32:48.600> minus<01:32:49.239> you<01:32:49.360> will<01:32:49.520> do 01:32:49.790 --> 01:32:49.800 align:start position:0% if you are doing like minus you will do 01:32:49.800 --> 01:32:52.669 align:start position:0% if you are doing like minus you will do this<01:32:50.199> uh<01:32:50.400> minus 01:32:52.669 --> 01:32:52.679 align:start position:0% this uh minus 01:32:52.679 --> 01:32:56.870 align:start position:0% this uh minus this<01:32:53.679> uh<01:32:54.040> um<01:32:54.719> yeah<01:32:54.920> so<01:32:55.320> this<01:32:56.000> function<01:32:56.760> this 01:32:56.870 --> 01:32:56.880 align:start position:0% this uh um yeah so this function this 01:32:56.880 --> 01:33:05.910 align:start position:0% this uh um yeah so this function this macr<01:32:57.320> sorry<01:32:57.679> is<01:32:57.880> kind<01:32:58.040> of<01:32:58.320> simple<01:32:59.280> and<01:32:59.760> then 01:33:05.910 --> 01:33:05.920 align:start position:0% 01:33:05.920 --> 01:33:08.470 align:start position:0% uh<01:33:06.920> I 01:33:08.470 --> 01:33:08.480 align:start position:0% uh I 01:33:08.480 --> 01:33:10.669 align:start position:0% uh I think<01:33:09.480> I<01:33:09.600> think<01:33:09.840> there<01:33:09.960> might<01:33:10.119> be<01:33:10.239> an<01:33:10.360> issue 01:33:10.669 --> 01:33:10.679 align:start position:0% think I think there might be an issue 01:33:10.679 --> 01:33:12.910 align:start position:0% think I think there might be an issue actually<01:33:11.000> with<01:33:11.159> the<01:33:11.320> code<01:33:11.920> yeah<01:33:12.159> okay<01:33:12.600> let's 01:33:12.910 --> 01:33:12.920 align:start position:0% actually with the code yeah okay let's 01:33:12.920 --> 01:33:15.790 align:start position:0% actually with the code yeah okay let's let's<01:33:13.080> see<01:33:13.360> how<01:33:13.560> it<01:33:14.159> how<01:33:14.320> it<01:33:14.520> works<01:33:15.159> I<01:33:15.320> wrote 01:33:15.790 --> 01:33:15.800 align:start position:0% let's see how it how it works I wrote 01:33:15.800 --> 01:33:18.350 align:start position:0% let's see how it how it works I wrote this<01:33:16.800> uh<01:33:16.960> the<01:33:17.080> test<01:33:17.320> was<01:33:17.560> passing<01:33:18.040> actually 01:33:18.350 --> 01:33:18.360 align:start position:0% this uh the test was passing actually 01:33:18.360 --> 01:33:20.590 align:start position:0% this uh the test was passing actually but<01:33:18.520> I<01:33:18.600> think<01:33:18.800> there<01:33:19.040> might<01:33:19.199> be<01:33:19.320> an<01:33:19.480> issue<01:33:20.360> from 01:33:20.590 --> 01:33:20.600 align:start position:0% but I think there might be an issue from 01:33:20.600 --> 01:33:23.350 align:start position:0% but I think there might be an issue from what<01:33:20.760> you<01:33:20.880> were<01:33:21.679> saying<01:33:22.119> earlier<01:33:22.840> so<01:33:23.159> let's 01:33:23.350 --> 01:33:23.360 align:start position:0% what you were saying earlier so let's 01:33:23.360 --> 01:33:24.590 align:start position:0% what you were saying earlier so let's see 01:33:24.590 --> 01:33:24.600 align:start position:0% see 01:33:24.600 --> 01:33:28.990 align:start position:0% see uh<01:33:24.840> then<01:33:25.560> uh<01:33:25.880> the<01:33:26.440> get<01:33:26.719> value<01:33:27.480> macro<01:33:28.440> is<01:33:28.800> kind 01:33:28.990 --> 01:33:29.000 align:start position:0% uh then uh the get value macro is kind 01:33:29.000 --> 01:33:32.870 align:start position:0% uh then uh the get value macro is kind of<01:33:29.320> similar<01:33:29.840> to<01:33:30.080> what<01:33:30.280> we've<01:33:30.840> been<01:33:31.840> doing<01:33:32.520> but 01:33:32.870 --> 01:33:32.880 align:start position:0% of similar to what we've been doing but 01:33:32.880 --> 01:33:35.229 align:start position:0% of similar to what we've been doing but yeah<01:33:33.080> we're<01:33:33.320> just<01:33:33.840> going<01:33:34.119> to<01:33:34.280> use<01:33:34.639> like<01:33:34.800> a<01:33:34.960> new 01:33:35.229 --> 01:33:35.239 align:start position:0% yeah we're just going to use like a new 01:33:35.239 --> 01:33:38.109 align:start position:0% yeah we're just going to use like a new up<01:33:35.560> code<01:33:35.960> called<01:33:36.800> uh<01:33:36.920> storage 01:33:38.109 --> 01:33:38.119 align:start position:0% up code called uh storage 01:33:38.119 --> 01:33:41.310 align:start position:0% up code called uh storage load<01:33:39.119> uh<01:33:39.520> and<01:33:39.800> it's<01:33:40.199> it's<01:33:40.520> very<01:33:40.800> simple<01:33:41.159> you 01:33:41.310 --> 01:33:41.320 align:start position:0% load uh and it's it's very simple you 01:33:41.320 --> 01:33:47.390 align:start position:0% load uh and it's it's very simple you just<01:33:41.520> say<01:33:42.119> I<01:33:42.239> want<01:33:42.480> to<01:33:43.199> load<01:33:44.360> into<01:33:45.360> uh 01:33:47.390 --> 01:33:47.400 align:start position:0% just say I want to load into uh 01:33:47.400 --> 01:33:52.629 align:start position:0% just say I want to load into uh the<01:33:48.400> uh<01:33:48.600> the<01:33:48.800> stack<01:33:49.400> I<01:33:49.480> want<01:33:49.679> to<01:33:50.000> load<01:33:51.000> uh<01:33:51.639> the 01:33:52.629 --> 01:33:52.639 align:start position:0% the uh the stack I want to load uh the 01:33:52.639 --> 01:33:55.430 align:start position:0% the uh the stack I want to load uh the sorry<01:33:53.080> I<01:33:53.159> want<01:33:53.320> to<01:33:53.480> load<01:33:53.960> into<01:33:54.239> the<01:33:54.480> stack<01:33:55.239> the 01:33:55.430 --> 01:33:55.440 align:start position:0% sorry I want to load into the stack the 01:33:55.440 --> 01:33:57.910 align:start position:0% sorry I want to load into the stack the value<01:33:55.760> that<01:33:55.880> is<01:33:56.040> stored<01:33:56.480> at<01:33:56.719> this<01:33:57.000> location<01:33:57.760> so 01:33:57.910 --> 01:33:57.920 align:start position:0% value that is stored at this location so 01:33:57.920 --> 01:33:59.990 align:start position:0% value that is stored at this location so we're<01:33:58.159> just<01:33:58.360> going<01:33:58.520> to<01:33:58.719> use<01:33:59.080> the<01:33:59.280> our<01:33:59.679> value 01:33:59.990 --> 01:34:00.000 align:start position:0% we're just going to use the our value 01:34:00.000 --> 01:34:02.669 align:start position:0% we're just going to use the our value location<01:34:00.679> constant<01:34:01.239> here<01:34:01.920> we<01:34:02.119> put<01:34:02.320> it<01:34:02.440> into 01:34:02.669 --> 01:34:02.679 align:start position:0% location constant here we put it into 01:34:02.679 --> 01:34:04.709 align:start position:0% location constant here we put it into the<01:34:02.840> bracket<01:34:03.679> then<01:34:03.800> we<01:34:03.960> just<01:34:04.080> say<01:34:04.360> yeah<01:34:04.520> I<01:34:04.600> want 01:34:04.709 --> 01:34:04.719 align:start position:0% the bracket then we just say yeah I want 01:34:04.719 --> 01:34:06.830 align:start position:0% the bracket then we just say yeah I want to<01:34:04.840> load<01:34:05.159> this<01:34:05.360> value<01:34:05.880> and<01:34:06.040> the<01:34:06.199> value<01:34:06.440> will<01:34:06.639> be 01:34:06.830 --> 01:34:06.840 align:start position:0% to load this value and the value will be 01:34:06.840 --> 01:34:08.870 align:start position:0% to load this value and the value will be put<01:34:07.080> into<01:34:07.320> the 01:34:08.870 --> 01:34:08.880 align:start position:0% put into the 01:34:08.880 --> 01:34:10.870 align:start position:0% put into the stack<01:34:09.880> and 01:34:10.870 --> 01:34:10.880 align:start position:0% stack and 01:34:10.880 --> 01:34:13.950 align:start position:0% stack and then<01:34:11.880> same<01:34:12.119> thing<01:34:12.400> as<01:34:12.639> before<01:34:13.159> we<01:34:13.360> put<01:34:13.719> this 01:34:13.950 --> 01:34:13.960 align:start position:0% then same thing as before we put this 01:34:13.960 --> 01:34:16.310 align:start position:0% then same thing as before we put this value<01:34:14.440> at<01:34:14.600> the<01:34:14.800> position<01:34:15.360> zero<01:34:15.800> into<01:34:16.119> the 01:34:16.310 --> 01:34:16.320 align:start position:0% value at the position zero into the 01:34:16.320 --> 01:34:18.910 align:start position:0% value at the position zero into the memory<01:34:17.320> and<01:34:17.520> then<01:34:17.760> we<01:34:17.880> call<01:34:18.360> return<01:34:18.600> and<01:34:18.800> we 01:34:18.910 --> 01:34:18.920 align:start position:0% memory and then we call return and we 01:34:18.920 --> 01:34:22.590 align:start position:0% memory and then we call return and we say<01:34:19.600> you<01:34:19.760> can<01:34:20.159> return<01:34:20.760> 32<01:34:21.320> bytes<01:34:22.040> starting<01:34:22.440> at 01:34:22.590 --> 01:34:22.600 align:start position:0% say you can return 32 bytes starting at 01:34:22.600 --> 01:34:24.669 align:start position:0% say you can return 32 bytes starting at the<01:34:22.760> position<01:34:23.239> Zero<01:34:23.520> from<01:34:23.719> from<01:34:23.840> the<01:34:23.960> memory 01:34:24.669 --> 01:34:24.679 align:start position:0% the position Zero from from the memory 01:34:24.679 --> 01:34:27.629 align:start position:0% the position Zero from from the memory and<01:34:24.840> they<01:34:25.000> will<01:34:25.400> return<01:34:25.600> the<01:34:26.000> value<01:34:27.000> so<01:34:27.480> kind 01:34:27.629 --> 01:34:27.639 align:start position:0% and they will return the value so kind 01:34:27.639 --> 01:34:30.310 align:start position:0% and they will return the value so kind of<01:34:27.920> straightforward<01:34:28.760> yeah<01:34:29.560> just<01:34:29.840> a<01:34:30.159> a 01:34:30.310 --> 01:34:30.320 align:start position:0% of straightforward yeah just a a 01:34:30.320 --> 01:34:32.709 align:start position:0% of straightforward yeah just a a different<01:34:30.600> kind<01:34:30.719> of<01:34:30.880> question<01:34:31.199> here<01:34:32.040> uh<01:34:32.199> if<01:34:32.360> I 01:34:32.709 --> 01:34:32.719 align:start position:0% different kind of question here uh if I 01:34:32.719 --> 01:34:34.550 align:start position:0% different kind of question here uh if I if<01:34:32.840> there's<01:34:33.040> a<01:34:33.159> smart<01:34:33.560> contract<01:34:34.239> that's<01:34:34.400> on 01:34:34.550 --> 01:34:34.560 align:start position:0% if there's a smart contract that's on 01:34:34.560 --> 01:34:36.390 align:start position:0% if there's a smart contract that's on the<01:34:34.800> that's<01:34:34.960> been<01:34:35.159> deployed<01:34:35.639> but<01:34:35.840> the<01:34:36.119> code 01:34:36.390 --> 01:34:36.400 align:start position:0% the that's been deployed but the code 01:34:36.400 --> 01:34:39.910 align:start position:0% the that's been deployed but the code was<01:34:36.560> not<01:34:37.000> published<01:34:38.000> can<01:34:38.239> you<01:34:39.040> um<01:34:39.280> decompile 01:34:39.910 --> 01:34:39.920 align:start position:0% was not published can you um decompile 01:34:39.920 --> 01:34:42.430 align:start position:0% was not published can you um decompile it<01:34:40.159> into<01:34:40.560> Huff<01:34:41.440> uh<01:34:41.600> I<01:34:41.679> think<01:34:41.880> there's<01:34:42.119> a 01:34:42.430 --> 01:34:42.440 align:start position:0% it into Huff uh I think there's a 01:34:42.440 --> 01:34:44.590 align:start position:0% it into Huff uh I think there's a decompiler<01:34:43.360> yeah<01:34:43.719> I'm<01:34:43.880> not<01:34:44.040> I'm<01:34:44.159> not<01:34:44.280> sure<01:34:44.480> if 01:34:44.590 --> 01:34:44.600 align:start position:0% decompiler yeah I'm not I'm not sure if 01:34:44.600 --> 01:34:45.390 align:start position:0% decompiler yeah I'm not I'm not sure if it's 01:34:45.390 --> 01:34:45.400 align:start position:0% it's 01:34:45.400 --> 01:34:48.390 align:start position:0% it's really<01:34:46.400> uh<01:34:46.960> powerful<01:34:47.679> but<01:34:47.880> I<01:34:47.960> think<01:34:48.119> there's 01:34:48.390 --> 01:34:48.400 align:start position:0% really uh powerful but I think there's 01:34:48.400 --> 01:34:50.189 align:start position:0% really uh powerful but I think there's one<01:34:48.679> yeah<01:34:48.920> there's<01:34:49.159> one<01:34:49.639> because<01:34:49.840> I<01:34:49.960> was<01:34:50.080> just 01:34:50.189 --> 01:34:50.199 align:start position:0% one yeah there's one because I was just 01:34:50.199 --> 01:34:51.870 align:start position:0% one yeah there's one because I was just thinking<01:34:50.440> in<01:34:50.520> terms<01:34:50.719> of<01:34:50.880> reverse<01:34:51.280> engineering 01:34:51.870 --> 01:34:51.880 align:start position:0% thinking in terms of reverse engineering 01:34:51.880 --> 01:34:54.310 align:start position:0% thinking in terms of reverse engineering the<01:34:52.159> smart<01:34:52.480> contract<01:34:53.000> right<01:34:53.719> you<01:34:53.800> can<01:34:53.920> use<01:34:54.080> it 01:34:54.310 --> 01:34:54.320 align:start position:0% the smart contract right you can use it 01:34:54.320 --> 01:34:57.709 align:start position:0% the smart contract right you can use it actually<01:34:55.080> yeah<01:34:55.280> that's<01:34:55.480> pretty<01:34:55.920> pretty 01:34:57.709 --> 01:34:57.719 align:start position:0% actually yeah that's pretty pretty 01:34:57.719 --> 01:35:00.430 align:start position:0% actually yeah that's pretty pretty nice<01:34:58.719> and<01:34:58.880> more<01:34:59.159> convenient<01:34:59.719> that<01:34:59.920> reading 01:35:00.430 --> 01:35:00.440 align:start position:0% nice and more convenient that reading 01:35:00.440 --> 01:35:03.629 align:start position:0% nice and more convenient that reading the<01:35:01.040> the<01:35:01.199> bite<01:35:01.440> code 01:35:03.629 --> 01:35:03.639 align:start position:0% the the bite code 01:35:03.639 --> 01:35:07.350 align:start position:0% the the bite code directly<01:35:04.840> um<01:35:05.840> yes<01:35:06.159> so<01:35:06.440> I<01:35:06.520> think<01:35:06.719> that's<01:35:06.920> it<01:35:07.080> for 01:35:07.350 --> 01:35:07.360 align:start position:0% directly um yes so I think that's it for 01:35:07.360 --> 01:35:08.990 align:start position:0% directly um yes so I think that's it for this<01:35:07.600> contract<01:35:08.440> it's<01:35:08.719> kind<01:35:08.840> of 01:35:08.990 --> 01:35:09.000 align:start position:0% this contract it's kind of 01:35:09.000 --> 01:35:11.510 align:start position:0% this contract it's kind of straightforward<01:35:09.760> we<01:35:09.920> already<01:35:10.320> saw<01:35:10.719> like<01:35:11.280> the 01:35:11.510 --> 01:35:11.520 align:start position:0% straightforward we already saw like the 01:35:11.520 --> 01:35:12.629 align:start position:0% straightforward we already saw like the function 01:35:12.629 --> 01:35:12.639 align:start position:0% function 01:35:12.639 --> 01:35:16.750 align:start position:0% function dispatching<01:35:13.639> uh<01:35:14.320> and<01:35:14.840> like<01:35:15.800> to<01:35:16.040> store<01:35:16.480> into 01:35:16.750 --> 01:35:16.760 align:start position:0% dispatching uh and like to store into 01:35:16.760 --> 01:35:19.310 align:start position:0% dispatching uh and like to store into the<01:35:16.920> storage<01:35:17.520> or<01:35:17.840> to<01:35:18.000> load<01:35:18.280> from<01:35:18.480> the<01:35:18.639> storage 01:35:19.310 --> 01:35:19.320 align:start position:0% the storage or to load from the storage 01:35:19.320 --> 01:35:22.709 align:start position:0% the storage or to load from the storage it's<01:35:19.520> very<01:35:20.119> simple<01:35:21.119> um<01:35:21.520> yeah<01:35:21.960> do<01:35:22.080> you<01:35:22.239> have<01:35:22.400> any 01:35:22.709 --> 01:35:22.719 align:start position:0% it's very simple um yeah do you have any 01:35:22.719 --> 01:35:42.390 align:start position:0% it's very simple um yeah do you have any questions<01:35:23.080> so<01:35:23.280> far 01:35:42.390 --> 01:35:42.400 align:start position:0% 01:35:42.400 --> 01:35:46.270 align:start

I'm<01:35:47.400> not<01:35:47.520> sure<01:35:47.920> yeah<01:35:48.080> I<01:35:48.159> think<01:35:48.320> it's 01:35:48.510 --> 01:35:48.520 align:start position:0% stop I'm not sure yeah I think it's 01:35:48.520 --> 01:35:50.229 align:start position:0% stop I'm not sure yeah I think it's needed<01:35:48.920> I'm<01:35:49.040> not<01:35:49.159> sure<01:35:49.320> if<01:35:49.440> it's<01:35:49.679> needed<01:35:50.000> or 01:35:50.229 --> 01:35:50.239 align:start position:0% needed I'm not sure if it's needed or 01:35:50.239 --> 01:35:57.709 align:start position:0% needed I'm not sure if it's needed or not 01:35:57.709 --> 01:35:57.719 align:start position:0% 01:35:57.719 --> 01:36:00.189 align:start position:0% let's<01:35:58.119> let's<01:35:58.920> see<01:35:59.320>

position:0% to Yol 01:36:24.600 --> 01:36:26.310 align:start position:0% to Yol uh<01:36:24.840> well<01:36:25.080> I<01:36:25.199> think 01:36:26.310 --> 01:36:26.320 align:start position:0% uh well I think 01:36:26.320 --> 01:36:29.590 align:start position:0% uh well I think like<01:36:27.320> well<01:36:27.520> the<01:36:27.639> main<01:36:28.000> difference<01:36:28.520> is<01:36:28.760> that<01:36:29.239> uh 01:36:29.590 --> 01:36:29.600 align:start position:0% like well the main difference is that uh 01:36:29.600 --> 01:36:31.990 align:start position:0% like well the main difference is that uh as<01:36:29.760> we<01:36:29.960> were<01:36:30.280> saying<01:36:30.639> like<01:36:30.840> earlier<01:36:31.239> you<01:36:31.400> have 01:36:31.990 --> 01:36:32.000 align:start position:0% as we were saying like earlier you have 01:36:32.000 --> 01:36:35.510 align:start position:0% as we were saying like earlier you have more<01:36:33.000> uh<01:36:33.480> Power<01:36:33.920> in<01:36:34.040> the<01:36:34.199> sense<01:36:34.520> that<01:36:35.080> even<01:36:35.320> in 01:36:35.510 --> 01:36:35.520 align:start position:0% more uh Power in the sense that even in 01:36:35.520 --> 01:36:38.430 align:start position:0% more uh Power in the sense that even in y<01:36:35.880> you<01:36:36.000> cannot<01:36:36.440> manipulate<01:36:37.320> the<01:36:37.639> stack<01:36:38.280> I 01:36:38.430 --> 01:36:38.440 align:start position:0% y you cannot manipulate the stack I 01:36:38.440 --> 01:36:40.750 align:start position:0% y you cannot manipulate the stack I think<01:36:39.400> uh<01:36:39.639> there<01:36:39.760> are<01:36:39.920> a<01:36:40.040> few<01:36:40.280> things<01:36:40.520> that<01:36:40.639> you 01:36:40.750 --> 01:36:40.760 align:start position:0% think uh there are a few things that you 01:36:40.760 --> 01:36:43.990 align:start position:0% think uh there are a few things that you cannot<01:36:41.119> do<01:36:42.119> uh<01:36:42.239> in<01:36:42.560> half<01:36:42.800> you<01:36:42.920> can<01:36:43.280> like<01:36:43.679> you 01:36:43.990 --> 01:36:44.000 align:start position:0% cannot do uh in half you can like you 01:36:44.000 --> 01:36:46.270 align:start position:0% cannot do uh in half you can like you you<01:36:44.119> can<01:36:44.360> like<01:36:44.560> duplicate<01:36:45.159> elements<01:36:45.920> in<01:36:46.080> the 01:36:46.270 --> 01:36:46.280 align:start position:0% you can like duplicate elements in the 01:36:46.280 --> 01:36:48.510 align:start position:0% you can like duplicate elements in the stack<01:36:46.600> you<01:36:46.719> can<01:36:46.920> like<01:36:47.119> swap<01:36:47.560> them<01:36:48.119> yeah<01:36:48.280> you're 01:36:48.510 --> 01:36:48.520 align:start position:0% stack you can like swap them yeah you're 01:36:48.520 --> 01:36:50.950 align:start position:0% stack you can like swap them yeah you're free<01:36:48.760> to<01:36:48.920> do<01:36:49.239> whatever<01:36:49.639> you<01:36:49.800> want<01:36:50.360> so<01:36:50.639> you<01:36:50.840> you 01:36:50.950 --> 01:36:50.960 align:start position:0% free to do whatever you want so you you 01:36:50.960 --> 01:36:54.950 align:start position:0% free to do whatever you want so you you can<01:36:51.199> do<01:36:51.440> like<01:36:52.000> more<01:36:52.440> optimized<01:36:53.239> things 01:36:54.950 --> 01:36:54.960 align:start position:0% can do like more optimized things 01:36:54.960 --> 01:36:59.669 align:start position:0% can do like more optimized things um<01:36:55.960> I<01:36:56.080> would<01:36:56.320> say<01:36:56.600> that's<01:36:57.600> about<01:36:57.960> it<01:36:58.360> but<01:36:59.360> yeah 01:36:59.669 --> 01:36:59.679 align:start position:0% um I would say that's about it but yeah 01:36:59.679 --> 01:37:01.629 align:start position:0% um I would say that's about it but yeah I<01:36:59.840> guess<01:37:00.119> it's<01:37:00.360> also<01:37:00.719> depends<01:37:01.040> on<01:37:01.199> the<01:37:01.320> use 01:37:01.629 --> 01:37:01.639 align:start position:0% I guess it's also depends on the use 01:37:01.639 --> 01:37:04.669 align:start position:0% I guess it's also depends on the use cases<01:37:02.119> but<01:37:03.040> yeah<01:37:03.320> I'm<01:37:03.639> not<01:37:03.920> aware<01:37:04.199> of<01:37:04.400> many 01:37:04.669 --> 01:37:04.679 align:start position:0% cases but yeah I'm not aware of many 01:37:04.679 --> 01:37:08.149 align:start position:0% cases but yeah I'm not aware of many contracts<01:37:05.280> that<01:37:05.440> were<01:37:05.760> written<01:37:06.199> in<01:37:06.600> pure<01:37:07.159> U 01:37:08.149 --> 01:37:08.159 align:start position:0% contracts that were written in pure U 01:37:08.159 --> 01:37:10.709 align:start position:0% contracts that were written in pure U but<01:37:08.560> uh<01:37:08.840> yeah<01:37:08.960> if<01:37:09.080> you're<01:37:09.280> using<01:37:09.760> like<01:37:10.000> U<01:37:10.560> like 01:37:10.709 --> 01:37:10.719 align:start position:0% but uh yeah if you're using like U like 01:37:10.719 --> 01:37:13.870 align:start position:0% but uh yeah if you're using like U like inline<01:37:11.280> assembly<01:37:11.719> in<01:37:12.040> solidity<01:37:13.040> then<01:37:13.199> I<01:37:13.280> mean 01:37:13.870 --> 01:37:13.880 align:start position:0% inline assembly in solidity then I mean 01:37:13.880 --> 01:37:15.750 align:start position:0% inline assembly in solidity then I mean the<01:37:14.199> the<01:37:14.320> obvious<01:37:14.679> reason<01:37:15.000> would<01:37:15.199> be<01:37:15.360> just<01:37:15.520> to 01:37:15.750 --> 01:37:15.760 align:start position:0% the the obvious reason would be just to 01:37:15.760 --> 01:37:19.070 align:start position:0% the the obvious reason would be just to you<01:37:16.000> to<01:37:16.159> be<01:37:16.760> optimizing<01:37:17.400> very<01:37:17.760> small<01:37:18.679> uh 01:37:19.070 --> 01:37:19.080 align:start position:0% you to be optimizing very small uh 01:37:19.080 --> 01:37:22.390 align:start position:0% you to be optimizing very small uh portions<01:37:20.080> knits<01:37:20.679> of<01:37:20.920> of 01:37:22.390 --> 01:37:22.400 align:start position:0% portions knits of of 01:37:22.400 --> 01:37:29.830 align:start position:0% portions knits of of code<01:37:23.400> uh<01:37:23.679> if<01:37:23.800> you<01:37:23.920> want 01:37:29.830 --> 01:37:29.840 align:start position:0% 01:37:29.840 --> 01:37:34.709 align:start position:0% to<01:37:30.840> yeah<01:37:31.040> so<01:37:31.239> this<01:37:31.360> is<01:37:31.560> the<01:37:32.280> test<01:37:33.280> for<01:37:33.960> the 01:37:34.709 --> 01:37:34.719 align:start position:0% to yeah so this is the test for the 01:37:34.719 --> 01:37:39.149 align:start position:0% to yeah so this is the test for the contract<01:37:35.719> uh<01:37:35.880> that<01:37:36.040> we<01:37:36.280> just<01:37:36.480> wrote<01:37:36.880> so<01:37:37.280> still 01:37:39.149 --> 01:37:39.159 align:start position:0% contract uh that we just wrote so still 01:37:39.159 --> 01:37:41.950 align:start position:0% contract uh that we just wrote so still very<01:37:40.159> very<01:37:40.480> simple<01:37:40.960> straightforward<01:37:41.679> we<01:37:41.800> are 01:37:41.950 --> 01:37:41.960 align:start position:0% very very simple straightforward we are 01:37:41.960 --> 01:37:45.790 align:start position:0% very very simple straightforward we are also<01:37:42.239> using<01:37:42.719> the<01:37:43.400> half<01:37:44.080> deployer<01:37:45.080> and<01:37:45.520> yeah<01:37:45.679> I 01:37:45.790 --> 01:37:45.800 align:start position:0% also using the half deployer and yeah I 01:37:45.800 --> 01:37:47.669 align:start position:0% also using the half deployer and yeah I add<01:37:46.000> did<01:37:46.159> some<01:37:46.480> console<01:37:46.880> log<01:37:47.119> just<01:37:47.239> for<01:37:47.520> the 01:37:47.669 --> 01:37:47.679 align:start position:0% add did some console log just for the 01:37:47.679 --> 01:37:49.229 align:start position:0% add did some console log just for the the<01:37:47.800> sake<01:37:48.080> of<01:37:48.280> it 01:37:49.229 --> 01:37:49.239 align:start position:0% the sake of it 01:37:49.239 --> 01:37:51.709 align:start position:0% the sake of it but<01:37:50.239> basically 01:37:51.709 --> 01:37:51.719 align:start position:0% but basically 01:37:51.719 --> 01:38:17.310 align:start position:0% but basically still<01:37:52.719> quite<01:37:52.920> straightforward 01:38:17.310 --> 01:38:17.320 align:start position:0% 01:38:17.320 --> 01:38:19.950 align:start position:0% word<01:38:18.320> I'll<01:38:18.520> just<01:38:18.679> give<01:38:18.840> you<01:38:18.960> a<01:38:19.080> few<01:38:19.440> minutes<01:38:19.880> if 01:38:19.950 --> 01:38:19.960 align:start position:0% word I'll just give you a few minutes if 01:38:19.960 --> 01:38:22.990 align:start position:0% word I'll just give you a few minutes if you<01:38:20.080> want<01:38:20.239> to<01:38:20.480> write<01:38:21.480> the<01:38:21.960> the<01:38:22.159> test<01:38:22.440> and<01:38:22.679> try 01:38:22.990 --> 01:38:23.000 align:start position:0% you want to write the the test and try 01:38:23.000 --> 01:38:31.229 align:start position:0% you want to write the the test and try out 01:38:31.229 --> 01:38:31.239 align:start position:0% 01:38:31.239 --> 01:38:35.350 align:start position:0% you<01:38:32.239> you<01:38:32.360> don't 01:38:35.350 --> 01:38:35.360 align:start position:0% 01:38:35.360 --> 01:38:46.350 align:start position:0% need<01:38:36.360> yeah 01:38:46.350 --> 01:38:46.360 align:start position:0% 01:38:46.360 --> 01:38:50.030 align:start position:0% yeah<01:38:47.360> are<01:38:47.520> you<01:38:47.760> running<01:38:48.320> the<01:38:49.159> oh<01:38:49.400> but<01:38:49.679> you<01:38:49.800> are 01:38:50.030 --> 01:38:50.040 align:start position:0% yeah are you running the oh but you are 01:38:50.040 --> 01:38:53.910 align:start position:0% yeah are you running the oh but you are running<01:38:50.440> the<01:38:50.599> test<01:38:50.920> from<01:38:51.560> counter<01:38:52.560> then<01:38:53.639> maybe 01:38:53.910 --> 01:38:53.920 align:start position:0% running the test from counter then maybe 01:38:53.920 --> 01:38:56.430 align:start position:0% running the test from counter then maybe the<01:38:54.040> other 01:38:56.430 --> 01:38:56.440 align:start position:0% 01:38:56.440 --> 01:39:05.550 align:start position:0% test<01:38:57.440> okay

--> 01:40:13.870 align:start position:0% how<01:40:11.239> is<01:40:11.360> it 01:40:13.870 --> 01:40:13.880 align:start position:0% 01:40:13.880 --> 01:40:27.910 align:start position:0% going<01:40:14.880> all<01:40:15.159> good 01:40:27.910 --> 01:40:27.920 align:start position:0% 01:40:27.920 --> 01:40:32.149 align:start position:0% it's<01:40:28.280> a<01:40:28.639> oh<01:40:28.800> you<01:40:28.920> added<01:40:29.280> more<01:40:29.960> things<01:40:31.159> nice 01:40:32.149 --> 01:40:32.159 align:start position:0% it's a oh you added more things nice 01:40:32.159 --> 01:40:43.629 align:start position:0% it's a oh you added more things nice okay<01:40:32.520> cool<01:40:33.520> all 01:40:43.629 --> 01:40:43.639 align:start position:0% 01:40:43.639 --> 01:40:47.270 align:start position:0% right<01:40:44.639> yeah<01:40:44.880> that<01:40:45.360> that's<01:40:46.360> uh<01:40:46.520> I<01:40:46.599> don't<01:40:46.840> have 01:40:47.270 --> 01:40:47.280 align:start position:0% right yeah that that's uh I don't have 01:40:47.280 --> 01:40:50.229 align:start position:0% right yeah that that's uh I don't have another<01:40:47.960> contract<01:40:48.560> after<01:40:48.920> that<01:40:49.639> so<01:40:50.000> if<01:40:50.119> you 01:40:50.229 --> 01:40:50.239 align:start position:0% another contract after that so if you

align:start position:0% return nothing just to see this will 01:42:50.360 --> 01:42:55.790 align:start position:0% return nothing just to see this will return<01:42:50.719> something<01:42:51.239> so<01:42:51.560> just<01:42:51.880> uh 01:42:55.790 --> 01:42:55.800 align:start position:0% 01:42:55.800 --> 01:42:58.750 align:start position:0% so<01:42:56.440> what<01:42:56.560> you<01:42:56.920> need<01:42:57.199> for<01:42:57.400> example<01:42:58.119> if<01:42:58.239> you<01:42:58.480> put 01:42:58.750 --> 01:42:58.760 align:start position:0% so what you need for example if you put 01:42:58.760 --> 01:43:01.589 align:start position:0% so what you need for example if you put like<01:42:59.400> zero<01:42:59.880> zero<01:43:00.440> return<01:43:00.840> it<01:43:00.960> would<01:43:01.199> just<01:43:01.360> end 01:43:01.589 --> 01:43:01.599 align:start position:0% like zero zero return it would just end 01:43:01.599 --> 01:43:03.910 align:start position:0% like zero zero return it would just end a<01:43:01.800> transaction<01:43:02.639> so<01:43:03.119> you<01:43:03.199> don't<01:43:03.440> have<01:43:03.560> to 01:43:03.910 --> 01:43:03.920 align:start position:0% a transaction so you don't have to 01:43:03.920 --> 01:43:06.430 align:start position:0% a transaction so you don't have to return<01:43:04.199> something<01:43:05.040> you<01:43:05.199> can<01:43:05.440> just<01:43:05.679> like<01:43:06.000> uh 01:43:06.430 --> 01:43:06.440 align:start position:0% return something you can just like uh 01:43:06.440 --> 01:43:08.910 align:start position:0% return something you can just like uh put<01:43:07.440> this<01:43:07.599> to<01:43:07.920> return 01:43:08.910 --> 01:43:08.920 align:start position:0% put this to return 01:43:08.920 --> 01:43:16.750 align:start position:0% put this to return transaction<01:43:09.920> uh<01:43:10.080> to<01:43:10.599> yeah<01:43:10.880> to<01:43:11.040> stop<01:43:11.320> the 01:43:16.750 -->

you<01:43:19.119> familiar 01:43:19.510 --> 01:43:19.520 align:start position:0% transaction and if uh are you familiar 01:43:19.520 --> 01:43:21.910 align:start position:0% transaction and if uh are

01:43:29.480 align:start position:0% it nice okay all good yeah if the tests 01:43:29.480 --> 01:43:32.830 align:start position:0% it nice okay all good yeah if the tests are<01:43:29.800> failing<01:43:30.440> you<01:43:30.599> might<01:43:30.840> want<01:43:31.159> to<01:43:31.599> add<01:43:32.599> uh 01:43:32.830 --> 01:43:32.840 align:start position:0% are failing you might want to add uh 01:43:32.840 --> 01:43:34.430 align:start position:0% are failing you might want to add uh here<01:43:33.119> I<01:43:33.199> think<01:43:33.560> it<01:43:33.639> would<01:43:33.800> be<01:43:34.000> better 01:43:34.430 --> 01:43:34.440 align:start position:0% here I think it would be better 01:43:34.440 --> 01:43:36.550 align:start position:0% here I think it would be better especially<01:43:34.840> if<01:43:34.920> you<01:43:35.040> change<01:43:35.360> the<01:43:35.520> code<01:43:36.320> uh 01:43:36.550 --> 01:43:36.560 align:start position:0% especially if you change the code uh 01:43:36.560 --> 01:43:38.470 align:start position:0% especially if you change the code uh here<01:43:36.920> you<01:43:37.040> can<01:43:37.239> do<01:43:37.520> like<01:43:37.840> uh<01:43:38.000> you<01:43:38.080> can<01:43:38.280> add 01:43:38.470 --> 01:43:38.480 align:start position:0% here you can do like uh you can add 01:43:38.480 --> 01:43:42.070 align:start position:0% here you can do like uh you can add after<01:43:38.800> that<01:43:39.000> line<01:43:40.000> uh<01:43:40.440> return<01:43:41.239> so<01:43:41.599> like<01:43:41.840> this 01:43:42.070 --> 01:43:42.080 align:start position:0% after that line uh return so like this 01:43:42.080 --> 01:43:44.550 align:start position:0% after that line uh return so like this but<01:43:42.280> instead<01:43:42.679> of<01:43:43.199> having<01:43:43.560> like<01:43:43.760> 20<01:43:44.199> here<01:43:44.440> you 01:43:44.550 --> 01:43:44.560 align:start position:0% but instead of having like 20 here you 01:43:44.560 --> 01:43:48.070 align:start position:0% but instead of having like 20 here you can<01:43:44.760> just<01:43:44.960> like<01:43:45.159> put<01:43:45.960> Z<01:43:46.480> zero<01:43:47.040> return<01:43:47.679> so<01:43:47.920> here 01:43:48.070 --> 01:43:48.080 align:start position:0% can just like put Z zero return so here 01:43:48.080 --> 01:43:50.629 align:start position:0% can just like put Z zero return so here you<01:43:48.199> can<01:43:48.360> just<01:43:48.560> like<01:43:48.920> return<01:43:49.199> nothing<01:43:50.199> so<01:43:50.520> this 01:43:50.629 --> 01:43:50.639 align:start position:0% you can just like return nothing so this 01:43:50.639 --> 01:43:54.270 align:start position:0% you can just like return nothing so this will<01:43:50.960> just<01:43:51.520> let<01:43:51.800> know<01:43:52.239> that<01:43:52.880> uh<01:43:53.440> uh<01:43:53.840> after 01:43:54.270 --> 01:43:54.280 align:start position:0% will just let know that uh uh after 01:43:54.280 --> 01:43:56.390 align:start position:0% will just let know that uh uh after calling<01:43:54.719> this<01:43:54.880> macro<01:43:55.639> then<01:43:55.800> you<01:43:55.960> just<01:43:56.119> have<01:43:56.280> to 01:43:56.390 --> 01:43:56.400 align:start position:0% calling this macro then you just have to 01:43:56.400 --> 01:43:59.430 align:start position:0% calling this macro then you just have to end<01:43:56.639> the<01:43:56.800> transaction<01:43:57.639> cuz<01:43:58.280> otherwise<01:43:59.280> what 01:43:59.430 --> 01:43:59.440 align:start position:0% end the transaction cuz otherwise what 01:43:59.440 --> 01:44:03.270 align:start position:0% end the transaction cuz otherwise what could<01:43:59.679> happen<01:44:00.000> is<01:44:00.679> that<01:44:01.679> uh<01:44:02.000> set<01:44:02.360> value<01:44:02.719> is 01:44:03.270 --> 01:44:03.280 align:start position:0% could happen is that uh set value is 01:44:03.280 --> 01:44:05.990 align:start position:0% could happen is that uh set value is executed<01:44:04.280> and<01:44:04.520> then<01:44:04.679> you<01:44:04.800> go<01:44:05.040> here<01:44:05.159> to<01:44:05.520> jump 01:44:05.990 --> 01:44:06.000 align:start position:0% executed and then you go here to jump 01:44:06.000 --> 01:44:08.390 align:start position:0% executed and then you go here to jump label<01:44:06.639> and<01:44:06.760> then<01:44:06.960> get<01:44:07.199> value<01:44:07.520> is<01:44:07.760> executed 01:44:08.390 --> 01:44:08.400 align:start position:0% label and then get value is executed 01:44:08.400 --> 01:44:10.830 align:start position:0% label and then get value is executed also<01:44:09.080> so<01:44:09.199> you<01:44:09.320> have<01:44:09.520> some<01:44:09.719> weird<01:44:10.040> scenarios<01:44:10.639> so 01:44:10.830 --> 01:44:10.840 align:start position:0% also so you have some weird scenarios so 01:44:10.840 --> 01:44:12.350 align:start position:0% also so you have some weird scenarios so I<01:44:10.920> think<01:44:11.080> it<01:44:11.159> would<01:44:11.320> be<01:44:11.520> just<01:44:11.679> better<01:44:11.960> to<01:44:12.119> do 01:44:12.350 --> 01:44:12.360 align:start position:0% I think it would be just better to do 01:44:12.360 --> 01:44:15.109 align:start position:0% I think it would be just better to do like<01:44:12.679> a<01:44:13.199> add<01:44:13.679> return<01:44:13.960> here<01:44:14.360> just<01:44:14.760> return 01:44:15.109 --> 01:44:15.119 align:start position:0% like a add return here just return 01:44:15.119 --> 01:44:17.390 align:start position:0% like a add return here just return nothing<01:44:15.639> just<01:44:15.840> Z<01:44:16.199> zero 01:44:17.390 --> 01:44:17.400 align:start position:0% nothing just Z zero 01:44:17.400 --> 01:44:21.109 align:start position:0% nothing just Z zero return<01:44:18.400> this<01:44:18.599> should<01:44:18.920> fix<01:44:19.679> things<01:44:20.679> if<01:44:20.880> if<01:44:21.000> you 01:44:21.109 --> 01:44:21.119 align:start position:0% return this should fix things if if you 01:44:21.119 --> 01:44:23.669 align:start position:0% return this should fix things if if you have<01:44:21.360> this<01:44:21.880> uh<01:44:22.320> it's<01:44:22.520> not<01:44:22.719> working<01:44:23.199> try<01:44:23.400> to<01:44:23.520> do 01:44:23.669 --> 01:44:23.679 align:start position:0% have this uh it's not working try to do 01:44:23.679 --> 01:44:25.390 align:start position:0% have this uh it's not working try to do what<01:44:23.800> I<01:44:24.000> just<01:44:24.199> said 01:44:25.390 --> 01:44:25.400 align:start position:0% what I just said 01:44:25.400 --> 01:44:38.550 align:start position:0% what I just said yeah<01:44:26.400> function<01:44:27.000> just<01:44:27.440> like 01:44:38.550 --> 01:44:38.560 align:start position:0% 01:44:38.560 --> 01:44:41.589 align:start position:0% yeah<01:44:39.560> yeah<01:44:39.719> stop<01:44:40.080> also<01:44:40.400> works<01:44:41.040> but<01:44:41.320> I'm<01:44:41.440> not 01:44:41.589 --> 01:44:41.599 align:start position:0% yeah yeah stop also works but I'm not 01:44:41.599 --> 01:44:44.109 align:start position:0% yeah yeah stop also works but I'm not sure<01:44:41.760> about<01:44:41.960> the<01:44:42.119> gas 01:44:44.109 --> 01:44:44.119 align:start position:0% sure about the gas 01:44:44.119 --> 01:44:46.550 align:start position:0% sure about the gas costs<01:44:45.119> yeah<01:44:45.239> you<01:44:45.360> can<01:44:45.560> stop<01:44:45.880> also<01:44:46.199> but<01:44:46.320> I'm<01:44:46.440> not 01:44:46.550 --> 01:44:46.560 align:start position:0% costs yeah you can stop also but I'm not 01:44:46.560 --> 01:44:48.990 align:start position:0% costs yeah you can stop also but I'm not sure<01:44:46.760> about<01:44:46.960> the<01:44:47.199> G<01:44:48.000> we<01:44:48.080> should<01:44:48.320> check<01:44:48.639> because 01:44:48.990 --> 01:44:49.000 align:start position:0% sure about the G we should check because 01:44:49.000 --> 01:44:51.669 align:start position:0% sure about the G we should check because sometimes<01:44:49.520> stop<01:44:49.760> is<01:44:49.960> just<01:44:50.199> like<01:44:50.880> consuming 01:44:51.669 --> 01:44:51.679 align:start position:0% sometimes stop is just like consuming 01:44:51.679 --> 01:44:54.229 align:start position:0% sometimes stop is just like consuming the<01:44:51.840> rest<01:44:52.040> of<01:44:52.239> the<01:44:53.080> the<01:44:53.280> G<01:44:53.520> or<01:44:53.800> things<01:44:54.040> like 01:44:54.229 --> 01:44:54.239 align:start position:0% the rest of the the G or things like 01:44:54.239 --> 01:44:57.229 align:start position:0% the rest of the the G or things like that<01:44:54.480> so<01:44:55.480> what<01:44:56.040> yeah<01:44:56.199> you<01:44:56.320> can<01:44:56.800> yeah<01:44:56.960>
