align:start position:0% network and so when you were going to say<00:01:47.350> from<00:01:47.500> the<00:01:47.619> network<00:01:47.920> one<00:01:48.159> of<00:01:48.250> the<00:01:48.310> etherium 00:01:48.899 --> 00:01:48.909 align:start position:0% say from the network one of the etherium 00:01:48.909 --> 00:01:51.419 align:start position:0% say from the network one of the etherium does<00:01:49.090> is<00:01:49.240> that<00:01:49.390> a<00:01:49.539> vacuum<00:01:49.959> in<00:01:50.429> gastrique 00:01:51.419 --> 00:01:51.429 align:start position:0% does is that a vacuum in

align:start position:0% good so we'll see how it plays out in 00:04:04.600 --> 00:04:06.780 align:start position:0% good so we'll see how it plays out in the<00:04:04.720> end 00:04:06.780 --> 00:04:06.790 align:start position:0% the end 00:04:06.790 --> 00:04:08.910 align:start position:0% the end and<00:04:07.239> in<00:04:07.600> how<00:04:07.750> people<00:04:07.900> are<00:04:08.110>

00:04:11.820 --> 00:04:11.830 align:start position:0% today a lot of the law has to do with 00:04:11.830 --> 00:04:14.580 align:start position:0% today a lot of the law has to do with the<00:04:11.920> arbitrage<00:04:12.310> so<00:04:12.790> the<00:04:13.090> idea<00:04:13.360> being<00:04:13.540> if<00:04:14.440> I 00:04:14.580 --> 00:04:14.590 align:start position:0% the arbitrage so the idea being if I 00:04:14.590 --> 00:04:16.170 align:start position:0% the arbitrage so the idea being if I want<00:04:14.739> to<00:04:14.799> make<00:04:14.920> a<00:04:14.950>

align:start position:0% want to make a transaction on unit swap and<00:04:16.690> make<00:04:16.870> some<00:04:17.049> arbitrage<00:04:17.470> through 00:04:17.789 --> 00:04:17.799 align:start position:0% and make some arbitrage through 00:04:17.799 --> 00:04:20.069 align:start position:0% and make some arbitrage through exchanges<00:04:18.280> and<00:04:19.120> I<00:04:19.209> might<00:04:19.419> have<00:04:19.450> a<00:04:19.660> dollar 00:04:20.069 --> 00:04:20.079 align:start position:0% exchanges and I might have a dollar 00:04:20.079 --> 00:04:22.380 align:start

--> 00:04:22.390 align:start position:0% profit to be made someone else with gas 00:04:22.390 --> 00:04:23.730 align:start position:0% profit to be made someone else with gas so<00:04:22.600> they<00:04:22.720> might<00:04:22.870> be<00:04:22.900> able<00:04:23.050> to<00:04:23.169> make<00:04:23.320> that<00:04:23.440> same 00:04:23.730 --> 00:04:23.740 align:start position:0% so they might be able to make that same 00:04:23.740 --> 00:04:25.920 align:start position:0% so they might be able to make that same transaction<00:04:24.460> what<00:04:24.700> they<00:04:24.820> can<00:04:25.000> do<00:04:25.120> is<00:04:25.240> use<00:04:25.479> gas 00:04:25.920 --> 00:04:25.930 align:start position:0% transaction what they can do is use gas 00:04:25.930 --> 00:04:28.140 align:start position:0% transaction what they can do is use gas token<00:04:26.350> and<00:04:26.560> like<00:04:26.979> I<00:04:27.100> said<00:04:27.280> it<00:04:27.550> reduces<00:04:27.970> the 00:04:28.140 --> 00:04:28.150 align:start position:0% token and like I said it reduces the 00:04:28.150 --> 00:04:30.870 align:start position:0% token and like I said it reduces the piece<00:04:28.740> sorry<00:04:29.740> the<00:04:29.860> gas<00:04:30.010> cost<00:04:30.310> and<00:04:30.520> so<00:04:30.669> what 00:04:30.870 --> 00:04:30.880 align:start position:0% piece sorry the gas cost and so what 00:04:30.880 --> 00:04:32.850 align:start position:0% piece sorry the gas cost and so what that<00:04:31.150> $1<00:04:31.570> downstairs<00:04:32.020> in<00:04:32.140> the<00:04:32.169> one<00:04:32.350> dollar<00:04:32.470> ten 00:04:32.850 --> 00:04:32.860 align:start position:0% that $1 downstairs in the one dollar ten 00:04:32.860 --> 00:04:34.830 align:start position:0% that $1 downstairs in the one dollar ten cents<00:04:33.160> for<00:04:33.220> someone<00:04:33.610> and<00:04:34.030> when<00:04:34.300> that<00:04:34.419> happens 00:04:34.830 --> 00:04:34.840 align:start position:0% cents for someone and when that happens 00:04:34.840 --> 00:04:38.610 align:start position:0% cents for someone and when that happens they<00:04:35.110> they<00:04:35.320> now<00:04:35.680> effectively<00:04:37.440> got<00:04:38.440> an 00:04:38.610 --> 00:04:38.620 align:start position:0% they they now effectively got an 00:04:38.620 --> 00:04:40.350 align:start position:0% they they now effectively got an advantage<00:04:39.100> in<00:04:39.220> arbitrage<00:04:39.640> that<00:04:39.700> no<00:04:40.000> one<00:04:40.120> else 00:04:40.350 --> 00:04:40.360 align:start position:0% advantage in arbitrage that no one else 00:04:40.360 --> 00:04:42.330 align:start position:0% advantage in arbitrage that no one else who<00:04:40.510> doesn't<00:04:40.810> have<00:04:40.870> gas<00:04:41.050> no<00:04:41.320> so<00:04:41.890> it's<00:04:42.220> pretty 00:04:42.330 --> 00:04:42.340 align:start position:0% who doesn't have gas no so it's pretty 00:04:42.340 --> 00:04:45.240 align:start position:0% who doesn't have gas no so it's pretty dangerous<00:04:42.580> in<00:04:42.910> that<00:04:43.060> sense<00:04:43.800> that's<00:04:44.800> usually<00:04:45.190> a 00:04:45.240 --> 00:04:45.250 align:start position:0% dangerous in that sense that's usually a 00:04:45.250 --> 00:04:46.740 align:start position:0%

align:start position:0% pretty well coupled with from running so 00:04:46.750 --> 00:04:48.420 align:start position:0% pretty well coupled with from running so a<00:04:47.080> lot<00:04:47.260>

00:05:28.820 --> 00:05:28.830 align:start position:0% to understand code to understand this 00:05:28.830 --> 00:05:31.350 align:start position:0% to understand code to understand this but<00:05:29.830> it<00:05:29.919> here's<00:05:30.310> the<00:05:30.550> whole<00:05:30.849> contract<00:05:31.210> you 00:05:31.350 --> 00:05:31.360 align:start position:0% but it here's the whole contract you 00:05:31.360 --> 00:05:33.779 align:start position:0% but it here's the whole contract you just<00:05:31.569> interacted<00:05:32.050> with<00:05:32.460> and<00:05:33.460> there's<00:05:33.669> only 00:05:33.779 --> 00:05:33.789 align:start position:0% just interacted with and there's only 00:05:33.789 --> 00:05:36.029 align:start position:0% just interacted with and there's only four<00:05:34.060> functions<00:05:34.539> so<00:05:34.719> so<00:05:34.960> here's<00:05:35.199> a<00:05:35.289> set<00:05:35.800> in 00:05:36.029 --> 00:05:36.039 align:start position:0% four functions so so here's a set in 00:05:36.039 --> 00:05:38.790 align:start position:0% four functions so so here's a set in ranked<00:05:36.310> seventh<00:05:37.180> in<00:05:37.240> rank<00:05:37.509> and<00:05:37.960> all<00:05:38.409> this<00:05:38.560> does 00:05:38.790 --> 00:05:38.800 align:start position:0% ranked seventh in rank and all this does 00:05:38.800 --> 00:05:40.709 align:start position:0% ranked seventh in rank and all this does is<00:05:38.830> set<00:05:39.159> a<00:05:39.189> rate<00:05:39.460> tokens<00:05:40.240> you<00:05:40.300> want<00:05:40.479> a<00:05:40.509> min<00:05:40.689> so 00:05:40.709 --> 00:05:40.719 align:start position:0% is set a rate tokens you want a min so 00:05:40.719 --> 00:05:43.589 align:start position:0% is set a rate tokens you want a min so this<00:05:41.139> would<00:05:41.349> say<00:05:41.620> you<00:05:42.400> need<00:05:42.550> 17<00:05:43.120> five<00:05:43.360> tokens 00:05:43.589 --> 00:05:43.599 align:start position:0% this would say you need 17 five tokens 00:05:43.599 --> 00:05:45.029 align:start position:0% this would say you need 17 five tokens per<00:05:43.900> transaction<00:05:44.259> so<00:05:44.650> that<00:05:44.680> when<00:05:44.949> you 00:05:45.029 --> 00:05:45.039 align:start position:0% per transaction so that when you 00:05:45.039 --> 00:05:47.070 align:start position:0% per transaction so that when you withdrew<00:05:45.370> from<00:05:45.520> from<00:05:46.090> an<00:05:46.180> exchange<00:05:46.360> you<00:05:46.870> meant 00:05:47.070 --> 00:05:47.080 align:start position:0% withdrew from from an exchange you meant 00:05:47.080 --> 00:05:48.749 align:start position:0% withdrew from from an exchange you meant five<00:05:47.259> tokens<00:05:47.500> and<00:05:47.830> you<00:05:47.889> can<00:05:48.039> change<00:05:48.250> this<00:05:48.490> and 00:05:48.749 --> 00:05:48.759 align:start position:0% five tokens and you can change this and 00:05:48.759 --> 00:05:50.519 align:start position:0% five tokens and you can change this and the<00:05:49.120> higher<00:05:49.330> the<00:05:49.539> rate<00:05:49.689> the<00:05:49.960> higher<00:05:50.259> your 00:05:50.519 --> 00:05:50.529 align:start position:0% the higher the rate the higher your 00:05:50.529 --> 00:05:52.580 align:start position:0% the higher the rate the higher your guests<00:05:50.770> limit<00:05:51.039> of<00:05:51.129> the<00:05:51.189> transaction<00:05:51.759> would<00:05:51.849> be 00:05:52.580 --> 00:05:52.590 align:start position:0% guests limit of the transaction would be 00:05:52.590 --> 00:05:55.619 align:start position:0% guests limit of the transaction would be the<00:05:53.590> actual<00:05:53.770> mint<00:05:54.189> function<00:05:54.639> again<00:05:55.360> this<00:05:55.479> is 00:05:55.619 --> 00:05:55.629 align:start position:0% the actual mint function again this is 00:05:55.629 --> 00:05:57.390 align:start position:0% the actual mint function again this is just<00:05:55.840> a<00:05:55.930> 12<00:05:56.199> token<00:05:56.620> it's<00:05:56.740> in<00:05:56.830> the<00:05:56.889> air<00:05:57.039> see<00:05:57.159> 20 00:05:57.390 --> 00:05:57.400 align:start position:0% just a 12 token it's in the air see 20 00:05:57.400 --> 00:05:59.429 align:start position:0% just a 12 token it's in the air see 20 token<00:05:57.759> and<00:05:57.789> so<00:05:58.539> you<00:05:58.629> just<00:05:58.810> call<00:05:58.930> toke<00:05:59.139> it<00:05:59.259> up 00:05:59.429 --> 00:05:59.439 align:start position:0% token and so you just call toke it up 00:05:59.439 --> 00:06:00.899 align:start position:0% token and so you just call toke it up mint<00:05:59.740> and<00:05:59.979> then<00:06:00.039> the<00:06:00.159> number<00:06:00.400> of<00:06:00.490> tokens<00:06:00.669> that 00:06:00.899 --> 00:06:00.909 align:start position:0% mint and then the number of tokens that 00:06:00.909 --> 00:06:03.540 align:start position:0% mint and then the number of tokens that you<00:06:01.000> pass<00:06:01.270> it<00:06:01.529> so<00:06:02.529> that's<00:06:02.710> also<00:06:02.860> very<00:06:02.979> simple 00:06:03.540 --> 00:06:03.550 align:start position:0% you pass it so that's also very simple 00:06:03.550 --> 00:06:05.760 align:start position:0% you pass it so that's also very simple this<00:06:04.150> is<00:06:04.210> the<00:06:04.479> fallback<00:06:04.659> function<00:06:05.199> so<00:06:05.409> the 00:06:05.760 --> 00:06:05.770 align:start position:0% this is the fallback function so the 00:06:05.770 --> 00:06:07.409 align:start position:0% this is the fallback function so the reason<00:06:06.279> this<00:06:06.370> works<00:06:06.580> what<00:06:06.789> the<00:06:06.879> changes<00:06:07.240> is 00:06:07.409 --> 00:06:07.419 align:start position:0% reason this works what the changes is 00:06:07.419 --> 00:06:09.209 align:start position:0% reason this works what the changes is when<00:06:07.539> you<00:06:08.050> don't<00:06:08.319> provide<00:06:08.529> data<00:06:08.860> to<00:06:09.009> a 00:06:09.209 --> 00:06:09.219 align:start position:0% when you don't provide data to a 00:06:09.219 --> 00:06:13.290 align:start position:0% when you don't provide data to a transaction<00:06:10.379> the<00:06:11.819> contract<00:06:12.819> automatically 00:06:13.290 --> 00:06:13.300 align:start position:0% transaction the contract automatically 00:06:13.300 --> 00:06:15.029 align:start position:0% transaction the contract automatically calls<00:06:13.509> the<00:06:13.629> fallback<00:06:13.870> function<00:06:14.440> in<00:06:14.620> this<00:06:14.830> case 00:06:15.029 --> 00:06:15.039 align:start position:0% calls the fallback function in this case 00:06:15.039 --> 00:06:17.369 align:start position:0% calls the fallback function in this case that<00:06:15.250> is<00:06:15.400> mint<00:06:15.729> so<00:06:16.300> now<00:06:16.419> it<00:06:16.599> takes<00:06:16.810> it<00:06:17.110> calls 00:06:17.369 --> 00:06:17.379 align:start position:0% that is mint so now it takes it calls 00:06:17.379 --> 00:06:18.899 align:start position:0% that is mint so now it takes it calls the<00:06:17.500> min<00:06:17.680> function<00:06:17.710> given<00:06:18.339> the<00:06:18.400> memory<00:06:18.729> you 00:06:18.899 --> 00:06:18.909 align:start position:0% the min function given the memory you 00:06:18.909 --> 00:06:20.879 align:start position:0% the min function given the memory you previously<00:06:19.360> provided<00:06:19.539> you<00:06:20.379> don't<00:06:20.529> need<00:06:20.650> to<00:06:20.740> do 00:06:20.879 --> 00:06:20.889 align:start position:0% previously provided you don't need to do 00:06:20.889 --> 00:06:22.260 align:start position:0% previously provided you don't need to do anything<00:06:21.250> these<00:06:21.400> change<00:06:21.699> now<00:06:21.909> is<00:06:22.089> basically 00:06:22.260 --> 00:06:22.270 align:start position:0% anything these change now is basically 00:06:22.270 --> 00:06:26.219 align:start position:0% anything these change now is basically paying<00:06:22.659> for<00:06:22.930> you<00:06:23.580> and<00:06:24.580> finally<00:06:24.789> you<00:06:25.779> can<00:06:26.080> with 00:06:26.219 --> 00:06:26.229 align:start position:0% paying for you and finally you can with 00:06:26.229 --> 00:06:28.320 align:start position:0% paying for you and finally you can with for<00:06:26.379> all<00:06:26.440> the<00:06:26.469> tokens<00:06:26.710> so<00:06:27.039> so<00:06:27.279> the<00:06:27.460> tokens<00:06:28.210> will 00:06:28.320 --> 00:06:28.330 align:start position:0% for all the tokens so so the tokens will 00:06:28.330 --> 00:06:30.209 align:start position:0% for all the tokens so so the tokens will live<00:06:28.479> on<00:06:28.659> the<00:06:28.839> on<00:06:29.289> the<00:06:29.440> contract<00:06:29.860> and<00:06:29.979> then<00:06:30.099> you 00:06:30.209 --> 00:06:30.219 align:start position:0% live on the on the contract and then you 00:06:30.219 --> 00:06:32.369 align:start position:0% live on the on the contract and then you would<00:06:30.339> throw<00:06:30.550> them<00:06:30.810> and<00:06:31.810> so<00:06:31.960> this<00:06:32.139> is<00:06:32.259> just 00:06:32.369 --> 00:06:32.379 align:start position:0% would throw them and so this is just 00:06:32.379 --> 00:06:33.869 align:start position:0% would throw them and so this is just transferring<00:06:32.800> the<00:06:32.889> tokens<00:06:33.250> out<00:06:33.339> as<00:06:33.580> well<00:06:33.729> as 00:06:33.869 --> 00:06:33.879 align:start position:0% transferring the tokens out as well as 00:06:33.879 --> 00:06:36.899 align:start position:0% transferring the tokens out as well as an<00:06:34.839> ether<00:06:35.169> there's<00:06:35.529> some<00:06:35.770> in<00:06:35.889> there<00:06:36.099> so<00:06:36.610> it's 00:06:36.899 --> 00:06:36.909 align:start position:0% an ether there's some in there so it's 00:06:36.909 --> 00:06:39.320 align:start position:0% an ether there's some in there so it's very<00:06:37.089> simple<00:06:37.389> to<00:06:37.509> execute<00:06:37.659> this<00:06:38.110> it's 00:06:39.320 --> 00:06:39.330 align:start position:0% very simple to execute this it's 00:06:39.330 --> 00:06:45.469 align:start position:0% very simple to execute this it's dangerously<00:06:40.330> simple<00:06:40.750> someone<00:06:41.259> say<00:06:43.830> here<00:06:44.830> is 00:06:45.469 --> 00:06:45.479 align:start position:0% dangerously simple someone say here is 00:06:45.479 --> 00:06:49.350 align:start position:0% dangerously simple someone say here is an<00:06:46.479> example<00:06:46.779> transaction<00:06:47.909> and<00:06:48.909> then<00:06:49.089> you 00:06:49.350 --> 00:06:49.360 align:start position:0% an example transaction and then you 00:06:49.360 --> 00:06:50.730 align:start position:0% an example transaction and then you probably<00:06:49.629> can't<00:06:49.810> see<00:06:49.960> this<00:06:50.110> but<00:06:50.289> it's<00:06:50.500> an 00:06:50.730 --> 00:06:50.740 align:start position:0% probably can't see this but it's an 00:06:50.740 --> 00:06:52.140 align:start position:0% probably can't see this but it's an ether<00:06:51.069> scan<00:06:51.310> contract<00:06:51.759> and<00:06:51.909> this<00:06:52.000> is<00:06:52.120> a 00:06:52.140 --> 00:06:52.150 align:start position:0% ether scan contract and this is a 00:06:52.150 --> 00:06:54.719 align:start position:0% ether scan contract and this is a

exchange and so we 00:06:54.729 --> 00:06:56.399 align:start position:0% withdrawal home an exchange and so we throw<00:06:54.909> all<00:06:55.029> a<00:06:55.089> point<00:06:55.389> on<00:06:55.539> one<00:06:55.659> ether<00:06:55.960> so<00:06:56.229> not 00:06:56.399 --> 00:06:56.409 align:start position:0% throw all a point on one ether so not 00:06:56.409 --> 00:06:58.290 align:start position:0% throw all a point on one ether so not nothing<00:06:56.740> too<00:06:56.860> crazy<00:06:57.039> but<00:06:57.759> if<00:06:57.939> you<00:06:58.089> look<00:06:58.270> here 00:06:58.290 --> 00:06:58.300 align:start position:0% nothing too crazy but if you look here 00:06:58.300 --> 00:07:01.740 align:start position:0% nothing too crazy but if you look here

00:07:18.160 align:start position:0% a gas price appropriate and and what 00:07:18.160 --> 00:07:19.379 align:start position:0% a gas price appropriate and and what people<00:07:18.400> can<00:07:18.550> do<00:07:18.639> with<00:07:18.729> this<00:07:18.850> not<00:07:19.150> taking 00:07:19.379 --> 00:07:19.389 align:start position:0% people can do with this not taking 00:07:19.389 --> 00:07:20.939 align:start position:0% people can do with this not taking advantage<00:07:19.720> of<00:07:19.810> it<00:07:19.960> in<00:07:20.080> print<00:07:20.320> yeah<00:07:20.440>

it in print yeah so and so this<00:07:21.100> is<00:07:21.280> the<00:07:21.669> first<00:07:21.910> transaction<00:07:22.330> we<00:07:22.720> did 00:07:22.890 --> 00:07:22.900 align:start

the user vulnerable so you can see<00:08:41.560> here<00:08:41.860> they<00:08:42.130> have<00:08:42.339> this<00:08:42.490> positive<00:08:42.700> network 00:08:43.510 --> 00:08:43.520 align:start position:0% see here they have this positive network 00:08:43.520 --> 00:08:50.020 align:start position:0% see here they have this positive network the<00:08:45.460> transaction<00:08:46.460>

00:08:51.550 align:start position:0% the transaction fee and users can almost guarantee<00:08:50.270> both<00:08:50.690> so<00:08:50.810> you<00:08:50.900> don't<00:08:51.080> look<00:08:51.230> at<00:08:51.380> that 00:08:51.550 --> 00:08:51.560 align:start position:0% guarantee both so you don't look at that 00:08:51.560 --> 00:08:53.560 align:start position:0% guarantee both so you don't look at that too<00:08:51.920> closely<00:08:52.130> and<00:08:52.670> but<00:08:53.120> what<00:08:53.270> these<00:08:53.420> are 00:08:53.560 --> 00:08:53.570 align:start position:0% too closely and but what these are 00:08:53.570 --> 00:08:56.110 align:start position:0% too closely and but what these are saying<00:08:53.810> is<00:08:53.990> hey<00:08:54.170> I'm<00:08:54.320>

I<00:09:13.850> don't<00:09:14.360> know<00:09:14.420> if<00:09:14.510> there's<00:09:14.690> a<00:09:14.750> good 00:09:14.860 --> 00:09:14.870 align:start position:0% and I don't know if there's a

position:0% abstract the gas away from the user and 00:09:18.860 --> 00:09:20.770 align:start position:0% abstract the gas away from the user and that's<00:09:19.250> a<00:09:19.340> really<00:09:19.520> good<00:09:19.640> idea<00:09:19.790> but<00:09:20.480> on<00:09:20.690> the 00:09:20.770 --> 00:09:20.780 align:start position:0% that's a really good idea but on the 00:09:20.780 --> 00:09:23.170 align:start position:0% that's a really good idea but on the same<00:09:20.990> at<00:09:21.590> the<00:09:21.710> same<00:09:21.890> time<00:09:22.100> it's<00:09:22.640> also 00:09:23.170 --> 00:09:23.180 align:start position:0% same at the same time it's also 00:09:23.180 --> 00:09:27.280 align:start position:0% same at the same time it's also dangerous<00:09:24.760> this<00:09:25.760> is<00:09:25.820> also<00:09:26.090> argent<00:09:26.660> and<00:09:26.870> the 00:09:27.280 --> 00:09:27.290 align:start position:0% dangerous this is also argent and the 00:09:27.290 --> 00:09:28.660 align:start position:0% dangerous this is also argent and the reason<00:09:27.560> it's<00:09:27.680> by<00:09:27.800> itself<00:09:28.100> is<00:09:28.310> because<00:09:28.490> they 00:09:28.660 --> 00:09:28.670 align:start position:0% reason it's by itself is because they 00:09:28.670 --> 00:09:30.880 align:start position:0% reason it's by itself is because they they<00:09:28.910> kind<00:09:29.120> of<00:09:29.210> do<00:09:29.840> it<00:09:29.990> the<00:09:30.260> worst<00:09:30.470> and<00:09:30.770> that 00:09:30.880 --> 00:09:30.890 align:start position:0% they kind of do it the worst and that 00:09:30.890 --> 00:09:33.040 align:start position:0% they kind of do it the worst and that they<00:09:31.070> say<00:09:31.490> it's<00:09:31.700> pretty<00:09:31.970> it's<00:09:32.210> made<00:09:32.360> by<00:09:32.540> argent 00:09:33.040 --> 00:09:33.050 align:start position:0% they say it's pretty it's made by argent 00:09:33.050 --> 00:09:34.990 align:start position:0% they say it's pretty it's made by argent so<00:09:33.350> they<00:09:33.470> don't<00:09:33.860> even<00:09:33.950> give<00:09:34.400> the<00:09:34.580> user<00:09:34.760> the 00:09:34.990 --> 00:09:35.000 align:start position:0% so they don't even give the user the 00:09:35.000 --> 00:09:37.120 align:start position:0% so they don't even give the user the idea<00:09:35.300> that<00:09:35.510> there<00:09:36.020> is<00:09:36.050> a<00:09:36.170> fee<00:09:36.440> associated<00:09:36.800> with 00:09:37.120

transaction<00:09:37.940> and<00:09:38.200> it's<00:09:39.200> dangerous<00:09:39.500> it's<00:09:39.890> nice 00:09:40.060 --> 00:09:40.070 align:start position:0% transaction and it's dangerous it's nice 00:09:40.070 --> 00:09:42.190 align:start position:0% transaction and it's dangerous it's nice but<00:09:40.310> it's<00:09:40.460> dangerous<00:09:40.610> and<00:09:41.060> so<00:09:41.210> it's<00:09:42.080> just 00:09:42.190 --> 00:09:42.200 align:start position:0% but it's dangerous and so it's just 00:09:42.200 --> 00:09:46.060 align:start position:0% but it's dangerous and so it's just something<00:09:42.380> to<00:09:42.680> look<00:09:42.800> out<00:09:42.950> for<00:09:44.560> and<00:09:45.560> then<00:09:45.830> going 00:09:46.060 --> 00:09:46.070 align:start position:0% something to look out for and then going 00:09:46.070 --> 00:09:48.880 align:start position:0% something to look out for and then going to<00:09:46.160> what<00:09:46.700> we<00:09:46.820> actually<00:09:47.030> did<00:09:47.510> last<00:09:48.110> year<00:09:48.290> so<00:09:48.440> so 00:09:48.880 --> 00:09:48.890 align:start position:0% to what we actually did last year so so 00:09:48.890 --> 00:09:51.340 align:start position:0% to what we actually did last year so so the<00:09:49.570> happened<00:09:50.570> would<00:09:50.690> be<00:09:50.720> the<00:09:51.020> exploit 00:09:51.340 --> 00:09:51.350 align:start position:0% the happened would be the exploit 00:09:51.350 --> 00:09:52.810 align:start position:0% the happened would be the exploit happened<00:09:51.740>

00:09:56.050 --> 00:09:56.060 align:start position:0% this time and we were basically 00:09:56.060 --> 00:09:58.360 align:start position:0% this time and we were basically realizing<00:09:56.930>

$2<00:10:05.240> but<00:10:05.510> if<00:10:05.720> you<00:10:05.810> were<00:10:05.930> a<00:10:05.960> script<00:10:06.380> you 00:10:06.460 --> 00:10:06.470 align:start position:0% some $2 but if

00:10:08.320 --> 00:10:08.330 align:start position:0% could basically take a million 00:10:08.330 --> 00:10:11.200 align:start position:0% could basically take a million transactions<00:10:09.310>

align:start position:0% we got so that's kind of the history of 00:13:39.300 --> 00:13:41.259 align:start position:0% we got so that's kind of the history of the<00:13:39.510> attack<00:13:39.839> you<00:13:40.050> know<00:13:40.170> gasps<00:13:40.440> token<00:13:40.860> but 00:13:41.259 --> 00:13:41.269 align:start position:0% the attack you know gasps token but 00:13:41.269 --> 00:13:43.759 align:start position:0% the attack you know gasps token but there's<00:13:42.269> a<00:13:42.329> lot<00:13:42.480> of<00:13:42.570> interesting<00:13:43.019> metrics<00:13:43.649> and 00:13:43.759 --> 00:13:43.769 align:start position:0% there's a lot of interesting metrics and 00:13:43.769 --> 00:13:45.590 align:start position:0% there's a lot of interesting metrics and stuff<00:13:43.980>

now<00:13:46.350> and<00:13:46.740> and<00:13:47.100> here's 00:13:47.269 --> 00:13:47.279 align:start position:0% and guests so get it now and and here's 00:13:47.279 --> 00:13:48.769 align:start

00:13:51.690 --> 00:13:54.439 align:start position:0% of describe that a pretty interesting way<00:13:52.430> I'm<00:13:53.430> sure<00:13:53.640> you<00:13:53.730> guys<00:13:53.880>

position:0% way I'm sure you guys have all seen this but<00:13:54.660> one<00:13:54.810> fair<00:13:55.230> one<00:13:55.410> was<00:13:55.560> going<00:13:55.829> on<00:13:55.980> the<00:13:56.100> gas 00:13:56.240 --> 00:13:56.250 align:start position:0% but one fair one was going on the gas 00:13:56.250 --> 00:13:58.519 align:start position:0% but one fair one was going on the gas prices<00:13:56.640> were<00:13:56.760> pretty<00:13:57.180> high<00:13:57.360> they're<00:13:58.320> lower 00:13:58.519 --> 00:13:58.529 align:start position:0% prices were pretty high they're lower 00:13:58.529 --> 00:14:00.769 align:start position:0% prices were pretty high they're lower now<00:13:58.800> but<00:13:59.040> I<00:13:59.130> assume<00:13:59.790> they'll<00:13:59.970>

assume they'll be higher at some<00:14:00.959> point<00:14:02.089> when<00:14:03.089> these<00:14:03.510> prices<00:14:04.079> are<00:14:04.170> high 00:14:04.340 --> 00:14:04.350 align:start

align:start position:0% people can really start taking advantage of<00:14:06.300> gas<00:14:06.510> tokens 00:14:07.240 --> 00:14:07.250 align:start position:0% of gas tokens 00:14:07.250 -->

position:0% start using this at much higher price 00:14:17.860 --> 00:14:21.610 align:start position:0% start using this at much higher price this<00:14:18.860> is<00:14:18.920> the<00:14:19.639> block<00:14:20.240> gas<00:14:20.480> limit<00:14:20.779> again<00:14:21.470> this 00:14:21.610 --> 00:14:21.620 align:start position:0% this is the block gas limit again this 00:14:21.620 --> 00:14:23.230 align:start position:0% this is the block gas limit again this was<00:14:21.800> made<00:14:21.949> about<00:14:22.069> two<00:14:22.339> weeks<00:14:22.519> ago<00:14:22.730> when<00:14:22.939> we 00:14:23.230 --> 00:14:23.240 align:start position:0% was made about two weeks ago when we 00:14:23.240 --> 00:14:25.210 align:start position:0% was made about two weeks ago when we were<00:14:23.389> rising<00:14:23.930> the<00:14:24.050> the<00:14:24.319> block<00:14:24.589> gas<00:14:24.829> them<00:14:25.040> into 00:14:25.210 --> 00:14:25.220 align:start position:0% were rising the the block gas them into 00:14:25.220 --> 00:14:26.769 align:start position:0% were rising the the block gas them into about<00:14:25.459> eight<00:14:25.670> and<00:14:26.029> a<00:14:26.089> half<00:14:26.120> up<00:14:26.420> and<00:14:26.449> we've<00:14:26.629> got 00:14:26.769 --> 00:14:26.779 align:start position:0% about eight and a half up and we've got 00:14:26.779 --> 00:14:29.470 align:start position:0% about eight and a half up and we've got up<00:14:26.899> to<00:14:26.990> ten<00:14:27.170> million<00:14:27.610> and<00:14:28.610> I<00:14:28.939> think<00:14:29.120> since<00:14:29.329> then 00:14:29.470 --> 00:14:29.480 align:start position:0% up to ten million and I think since then 00:14:29.480 --> 00:14:31.119 align:start position:0% up to ten million and I think since then expect<00:14:29.810> on<00:14:29.959> the<00:14:30.110> eighth<00:14:30.199> but<00:14:30.439> but<00:14:30.620> this<00:14:30.829> is 00:14:31.119 --> 00:14:31.129 align:start position:0% expect on the eighth but but this is 00:14:31.129 --> 00:14:33.009 align:start position:0% expect on the eighth but but this is basically<00:14:31.459> showing<00:14:31.579> that<00:14:31.879> gas<00:14:32.209> usage<00:14:32.660> is 00:14:33.009 --> 00:14:33.019 align:start position:0% basically showing that gas usage is 00:14:33.019 --> 00:14:35.220 align:start position:0% basically showing that gas usage is really<00:14:33.860> increasing<00:14:34.370> on<00:14:34.459> the<00:14:34.550> network<00:14:34.850> and 00:14:35.220 --> 00:14:35.230 align:start position:0% really increasing on the network and 00:14:35.230 --> 00:14:37.689 align:start position:0% really increasing on the network and good<00:14:36.230> or<00:14:36.589> bad<00:14:36.740> maybe<00:14:37.100> it's<00:14:37.250> a<00:14:37.339> Ponzi<00:14:37.670> scheme 00:14:37.689 --> 00:14:37.699 align:start position:0% good or bad maybe it's a Ponzi scheme 00:14:37.699 --> 00:14:39.939 align:start position:0% good or bad maybe it's a Ponzi scheme maybe<00:14:38.120> we<00:14:38.509> have<00:14:38.689> a<00:14:38.720> lot<00:14:39.019> of<00:14:39.110> actual<00:14:39.410> usage<00:14:39.740> but 00:14:39.939 --> 00:14:39.949 align:start position:0% maybe we have a lot of actual usage but 00:14:39.949 --> 00:14:42.579 align:start position:0% maybe we have a lot of actual usage but but<00:14:40.189> my<00:14:40.730> intuition<00:14:41.540> is<00:14:41.870> that<00:14:41.899> etherium<00:14:42.500> is 00:14:42.579 --> 00:14:42.589 align:start position:0% but my intuition is that etherium is 00:14:42.589 --> 00:14:44.110 align:start position:0% but my intuition is that etherium is going<00:14:42.709> to<00:14:42.769> grow<00:14:42.949> and<00:14:43.339> the<00:14:43.490> usage<00:14:43.819> is<00:14:43.970> also 00:14:44.110 --> 00:14:44.120 align:start position:0% going to grow and the usage is also 00:14:44.120 --> 00:14:47.019 align:start position:0% going to grow and the usage is also going<00:14:44.389> to<00:14:44.449> grow<00:14:45.339> this<00:14:46.339> is<00:14:46.550> actually<00:14:46.910> pretty 00:14:47.019 --> 00:14:47.029 align:start position:0% going to grow this is actually pretty 00:14:47.029 --> 00:14:50.650 align:start position:0% going to grow this is actually pretty interesting<00:14:47.329> so<00:14:47.720> so<00:14:47.990> after<00:14:48.470> the<00:14:49.420> mud<00:14:50.420> this 00:14:50.650 --> 00:14:50.660 align:start position:0% interesting so so after the mud this 00:14:50.660 --> 00:14:53.050 align:start position:0% interesting so so after the mud this stuff<00:14:50.899> stem<00:14:51.170> from<00:14:51.350> fill<00:14:51.589> dance<00:14:51.920> talk<00:14:52.370> last

doing<00:14:58.519> was<00:14:59.089> mining<00:14:59.990> blocks<00:15:00.230> and<00:15:00.470> only 00:15:00.730 --> 00:15:00.740 align:start position:0% started doing was mining blocks and only 00:15:00.740 --> 00:15:03.009 align:start position:0% started doing was mining blocks and only filling<00:15:01.069> it<00:15:01.160> with<00:15:01.189> gas<00:15:01.459> token<00:15:01.879>

all 00:15:04.370 --> 00:15:06.939 align:start position:0% so you can see here at all most<00:15:04.790> of<00:15:04.939> these<00:15:05.060> transactions<00:15:05.689> are<00:15:05.870>

00:15:09.009 --> 00:15:11.740 align:start position:0% transaction fee meaning the miner included<00:15:10.009> his<00:15:10.160> own<00:15:10.310> transaction<00:15:10.970> and<00:15:11.240> you 00:15:11.740 --> 00:15:11.750 align:start position:0% included his own transaction and you 00:15:11.750 --> 00:15:13.449 align:start position:0% included his own transaction and you paid<00:15:11.959> zero<00:15:11.990> for<00:15:12.529> it<00:15:12.649> so<00:15:12.949> he<00:15:13.129> didn't<00:15:13.309> have<00:15:13.370> to 00:15:13.449 --> 00:15:13.459 align:start position:0% paid zero for

what's<00:15:33.019> happening<00:15:33.350> with<00:15:33.529> that<00:15:33.709> is 00:15:33.999 --> 00:15:34.009 align:start position:0% price and what's happening with that is 00:15:34.009 --> 00:15:37.540 align:start position:0% price and what's happening with that is it's<00:15:34.490> a<00:15:35.050> win-win<00:15:36.050> for<00:15:36.079> the<00:15:36.319> miner<00:15:37.189> because 00:15:37.540 --> 00:15:37.550 align:start position:0% it's a win-win for the miner because 00:15:37.550 --> 00:15:39.129 align:start position:0% it's a win-win for the miner because they<00:15:37.699> get<00:15:37.850> gas<00:15:38.089> tokens<00:15:38.480> but<00:15:38.600> what<00:15:38.750> happens<00:15:39.019> is 00:15:39.129 --> 00:15:39.139 align:start position:0% they get gas tokens but what happens is 00:15:39.139 --> 00:15:40.720 align:start position:0% they get gas tokens but what happens is they<00:15:39.230> also<00:15:39.410> start<00:15:39.740> clogging<00:15:40.129>

00:17:21.410 --> 00:17:23.740 align:start position:0% is is you can imagine this is in the air see<00:17:21.559> 20<00:17:21.829> token<00:17:22.189> and<00:17:22.459> so<00:17:23.000>

know<00:23:01.690> there's<00:23:01.960> two<00:23:02.170> different 00:23:02.550 --> 00:23:02.560 align:start position:0% yeah so I know there's two different 00:23:02.560 --> 00:23:09.650 align:start position:0% yeah so I know there's two different variants<00:23:03.420> can<00:23:05.400> you<00:23:06.750> Marian<00:23:07.750> yeah<00:23:08.320> so<00:23:08.640> there's 00:23:09.650 --> 00:23:09.660 align:start position:0% variants can you Marian yeah so there's 00:23:09.660 --> 00:23:12.750 align:start position:0% variants can you Marian yeah so there's the<00:23:10.660> the<00:23:10.900> deeper<00:23:11.890> answer<00:23:12.040> to<00:23:12.280> that<00:23:12.400> is<00:23:12.550> go<00:23:12.700> to 00:23:12.750 --> 00:23:12.760 align:start position:0% the the

I<00:23:14.170> think<00:23:14.310> the<00:23:15.310> quick 00:23:15.840 --> 00:23:15.850 align:start position:0% guest opium die oh I think the quick 00:23:15.850 --> 00:23:17.190 align:start position:0% guest opium die oh I think the quick answer<00:23:16.030> is<00:23:16.180> there's<00:23:16.480> two<00:23:16.660> ways<00:23:16.810> to<00:23:16.840> get<00:23:17.140> a 00:23:17.190 --> 00:23:17.200 align:start position:0% answer is there's two ways to get a 00:23:17.200 --> 00:23:20.760 align:start position:0% answer is there's two ways to get a refund<00:23:17.530> on<00:23:17.710> aetherium<00:23:18.130> one<00:23:18.700> is<00:23:19.090> to<00:23:19.770> reduce 00:23:20.760 --> 00:23:20.770 align:start position:0% refund on aetherium one is to reduce 00:23:20.770 --> 00:23:23.130 align:start position:0% refund on aetherium one is to reduce states<00:23:21.130> so<00:23:21.400> setting<00:23:21.790> a<00:23:22.060> variable<00:23:22.480> from<00:23:22.780> one<00:23:22.990> to 00:23:23.130 --> 00:23:23.140 align:start position:0% states so setting a variable from one to 00:23:23.140 --> 00:23:26.010 align:start position:0% states so setting a variable from one to zero<00:23:23.550> excess<00:23:24.550> refund<00:23:24.910> another<00:23:25.510> way<00:23:25.660> to<00:23:25.720> do<00:23:25.870> it 00:23:26.010 --> 00:23:26.020 align:start position:0% zero excess refund another way to do it 00:23:26.020 --> 00:23:28.140 align:start position:0% zero excess refund another way to do it is<00:23:26.140> to<00:23:26.260> self<00:23:26.500> destruct<00:23:26.710> a<00:23:26.980> contract<00:23:27.430> I<00:23:27.670> think 00:23:28.140 --> 00:23:28.150 align:start position:0% is to self destruct a contract I think 00:23:28.150 --> 00:23:29.700 align:start position:0% is to self destruct a contract I think that's<00:23:28.330> the<00:23:28.480> more<00:23:28.630> efficient<00:23:28.960> way<00:23:29.140> and<00:23:29.440> so<00:23:29.590> if 00:23:29.700 --> 00:23:29.710 align:start position:0% that's the more efficient way and so if 00:23:29.710 --> 00:23:31.560 align:start position:0% that's the more efficient way and so if you<00:23:29.860> basically<00:23:30.100> create<00:23:30.430> what<00:23:31.090> gasps<00:23:31.240> spoken 00:23:31.560 --> 00:23:31.570 align:start position:0% you basically create what gasps spoken 00:23:31.570 --> 00:23:33.780 align:start position:0% you basically create what gasps spoken to<00:23:31.690> does<00:23:31.870> it<00:23:31.900> creates<00:23:32.290> the<00:23:33.280> thousand 00:23:33.780 --> 00:23:33.790 align:start position:0% to does it creates the thousand 00:23:33.790 --> 00:23:35.850 align:start position:0% to does it creates the thousand contracts<00:23:34.180> for<00:23:34.360> you<00:23:34.420> and<00:23:34.750> when<00:23:35.260> you<00:23:35.380> go<00:23:35.620> to<00:23:35.680> use 00:23:35.850 --> 00:23:35.860 align:start position:0% contracts for you and when you go to use 00:23:35.860 --> 00:23:37.560 align:start position:0% contracts for you and when you go to use it<00:23:35.890> you<00:23:36.220> just<00:23:36.280> destroy<00:23:36.790> some<00:23:37.000> contracts<00:23:37.360> and 00:23:37.560 --> 00:23:37.570 align:start position:0% it you just destroy some contracts and 00:23:37.570 --> 00:23:40.410 align:start position:0% it you just destroy some contracts and that's<00:23:37.660> the<00:23:37.930> peppery<00:23:38.530> one<00:23:38.740> so<00:23:39.610> but<00:23:39.880>
