00:01:27.300 --> 00:01:27.310 align:start position:0% I use light node inside an electron app 00:01:27.310 --> 00:01:29.639 align:start position:0% I use light node inside an electron app right<00:01:28.119> now<00:01:28.179> like<00:01:28.570> clients<00:01:28.960> same<00:01:29.109> thing<00:01:29.289> so 00:01:29.639 --> 00:01:29.649 align:start position:0% right now like clients same thing so 00:01:29.649 --> 00:01:31.469 align:start position:0% right now like clients same thing so let's<00:01:29.829> start<00:01:30.039> why<00:01:30.280> light<00:01:30.909>

are important<00:01:32.079> so<00:01:32.770> first<00:01:32.979> of<00:01:33.100> all<00:01:33.159> you<00:01:33.820> probably 00:01:34.020 --> 00:01:34.030 align:start position:0% important so first of all you probably 00:01:34.030 --> 00:01:35.940 align:start position:0% important so first of all you probably all<00:01:34.329> know<00:01:34.359> but<00:01:34.840> running<00:01:35.140>

00:07:14.450 align:start position:0% theorem and what we want to do so yeah 00:07:14.450 --> 00:07:17.850 align:start position:0% theorem and what we want to do so yeah these<00:07:15.200> guys<00:07:15.470> can<00:07:15.980> eventually<00:07:16.330> censor<00:07:17.330> you<00:07:17.540> or 00:07:17.850 --> 00:07:17.860 align:start position:0% these guys can eventually censor you or 00:07:17.860 --> 00:07:21.490 align:start position:0% these guys can eventually censor you or or<00:07:18.860> track<00:07:19.430> you<00:07:19.610> and<00:07:19.880> so<00:07:20.450> what<00:07:20.630> we<00:07:20.750> what<00:07:21.170> we<00:07:21.200> want 00:07:21.490 --> 00:07:21.500 align:start position:0% or track you and so what we what we want 00:07:21.500 --> 00:07:23.710 align:start position:0% or track you and so what we what we want to<00:07:21.620> do<00:07:21.740> with<00:07:22.400> this<00:07:22.610> light<00:07:22.850> J's<00:07:23.120> is<00:07:23.360> actually 00:07:23.710 --> 00:07:23.720 align:start position:0% to do with this light J's is actually 00:07:23.720 --> 00:07:25.480 align:start position:0% to do with this light J's is actually instead<00:07:24.020> of<00:07:24.170> what<00:07:24.320> three<00:07:24.470> J's<00:07:24.770> you<00:07:24.800> use<00:07:25.250> this 00:07:25.480 --> 00:07:25.490 align:start position:0% instead of what three J's you use this 00:07:25.490 --> 00:07:28.690 align:start position:0% instead of what three J's you use this light<00:07:25.730> Jess<00:07:26.030> and<00:07:26.360> this<00:07:27.260> will<00:07:27.980> talk<00:07:28.190> to<00:07:28.460> a<00:07:28.490> light 00:07:28.690 --> 00:07:28.700 align:start position:0% light Jess and this will talk to a light 00:07:28.700 --> 00:07:31.330 align:start position:0% light Jess and this will talk to a light node<00:07:28.970> on<00:07:29.270> your<00:07:29.720> own<00:07:29.900> inside<00:07:30.680> your<00:07:31.010> app 00:07:31.330 --> 00:07:31.340 align:start position:0% node on your own inside your app 00:07:31.340 --> 00:07:34.600 align:start position:0% node on your own inside your app actually<00:07:31.850> and<00:07:32.560> you<00:07:33.560> will<00:07:33.710> talk<00:07:33.890> directly<00:07:34.310> to 00:07:34.600 --> 00:07:34.610 align:start position:0% actually and you will talk directly to 00:07:34.610 --> 00:07:37.480 align:start position:0% actually and you will talk directly to the<00:07:35.230> ethereum<00:07:36.230> network<00:07:36.560> so<00:07:36.800> the<00:07:37.100> difference 00:07:37.480 --> 00:07:37.490 align:start position:0% the ethereum network so the difference 00:07:37.490 --> 00:07:39.160 align:start position:0% the ethereum network so the difference here<00:07:37.760> is<00:07:37.790> that<00:07:38.180> you<00:07:38.330> remove<00:07:38.660> write<00:07:38.990> the 00:07:39.160 --> 00:07:39.170 align:start position:0% here is that you remove write the 00:07:39.170 --> 00:07:40.960 align:start position:0% here is that you remove write the centralized<00:07:39.650> node<00:07:39.860> and<00:07:40.070> you<00:07:40.100> put<00:07:40.610> the<00:07:40.790> light 00:07:40.960 --> 00:07:40.970 align:start position:0% centralized node and you put the light 00:07:40.970 --> 00:07:45.550 align:start position:0% centralized node and you put the light node<00:07:41.240> actually<00:07:41.480> inside<00:07:42.050> the<00:07:42.110> tap<00:07:42.410> right<00:07:44.560> so 00:07:45.550 --> 00:07:45.560 align:start position:0% node actually inside the tap right so 00:07:45.560 --> 00:07:50.950 align:start position:0% node actually inside the tap right so this<00:07:47.230> like<00:07:48.230> Jess<00:07:48.530> library<00:07:49.340> is<00:07:49.610> a<00:07:50.540> high-level 00:07:50.950 --> 00:07:50.960 align:start position:0% this like Jess library is a high-level 00:07:50.960 --> 00:07:54.910 align:start

00:08:00.130 --> 00:08:00.140 align:start position:0% we are whoa how do you install it just 00:08:00.140 --> 00:08:01.840 align:start position:0% we are whoa how do you install it just like<00:08:00.260> any<00:08:00.440> other<00:08:00.620> real<00:08:00.950> library<00:08:01.280> you<00:08:01.430> probably 00:08:01.840 --> 00:08:01.850 align:start position:0% like any other real library you probably 00:08:01.850 --> 00:08:05.290 align:start position:0% like any other real library you probably insulted<00:08:02.120> a<00:08:02.920> it's<00:08:03.920> from<00:08:04.280> the<00:08:04.430> party<00:08:04.820> name<00:08:05.000> face 00:08:05.290 --> 00:08:05.300 align:start position:0% insulted a it's from the party name face 00:08:05.300 --> 00:08:09.190 align:start

have<00:08:09.140> a 00:08:09.190 --> 00:08:09.200 align:start position:0% and slash like dot J's so let's have a 00:08:09.200 --> 00:08:11.200 align:start position:0% and slash like dot J's so let's have a look<00:08:09.320> a<00:08:09.470> bit<00:08:09.650> at<00:08:09.800> some<00:08:10.190> code<00:08:10.430> I<00:08:10.670> hope<00:08:10.850> you<00:08:11.030> can 00:08:11.200 --> 00:08:11.210 align:start position:0% look a bit at some code I hope you can 00:08:11.210 --> 00:08:13.720 align:start position:0% look a bit at some code I hope you can see<00:08:11.390> that<00:08:11.420> all<00:08:11.840> right<00:08:12.080> so<00:08:12.890> that's<00:08:13.400> a<00:08:13.580> really 00:08:13.720 --> 00:08:13.730 align:start position:0% see that all right so that's a really 00:08:13.730 --> 00:08:17.020 align:start position:0% see that all right so that's a really simple<00:08:13.850> sample<00:08:14.600> code<00:08:15.190> so<00:08:16.190> you<00:08:16.220>

align:start position:0% off and block number and those balance often<00:08:23.840> drop<00:08:24.050> number<00:08:24.320> have<00:08:24.500> a<00:08:24.530> dollar<00:08:25.420> behind 00:08:26.410 --> 00:08:26.420 align:start position:0% often drop number have a dollar behind 00:08:26.420 --> 00:08:27.820 align:start position:0% often drop number have a dollar behind and<00:08:26.660> it<00:08:26.840> means<00:08:27.020> there<00:08:27.230> are<00:08:27.320> these<00:08:27.560> are 00:08:27.820 --> 00:08:27.830 align:start position:0% and it means there are these are 00:08:27.830 --> 00:08:30.220 align:start position:0% and it means there are these are observable<00:08:28.670> and<00:08:28.880> just<00:08:29.510> like<00:08:29.690> we<00:08:29.870> would<00:08:30.080> do 00:08:30.220 --> 00:08:30.230 align:start position:0% observable and just like we would do 00:08:30.230 --> 00:08:32.650 align:start position:0% observable and just like we would do with<00:08:30.410> web<00:08:30.620> 3gs<00:08:31.070> today<00:08:31.520> you<00:08:32.060> would<00:08:32.240> just<00:08:32.450> do 00:08:32.650 --> 00:08:32.660 align:start position:0% with web 3gs today you would just do 00:08:32.660 --> 00:08:34.690 align:start position:0% with web 3gs today you would just do light<00:08:32.870> set<00:08:33.290> provider<00:08:33.680> with<00:08:34.160> your<00:08:34.310>

and<00:08:35.060> then<00:08:35.840> you<00:08:35.990> can<00:08:36.200> do<00:08:36.410> with<00:08:36.770> these 00:08:36.880 --> 00:08:36.890 align:start position:0% and then you can do with these 00:08:36.890 --> 00:08:38.770 align:start position:0% and then you can do with these observables<00:08:37.610> Rock<00:08:37.940> number<00:08:38.330> you<00:08:38.570> can 00:08:38.770 --> 00:08:38.780 align:start position:0% observables Rock number you can 00:08:38.780 --> 00:08:41.650 align:start position:0% observables Rock number you can subscribe<00:08:39.080> for<00:08:39.349> instance<00:08:39.919> and<00:08:40.479> this<00:08:41.479> will 00:08:41.650 --> 00:08:41.660 align:start position:0% subscribe for instance and this will 00:08:41.660 --> 00:08:43.540 align:start position:0% subscribe for instance and this will give<00:08:42.020> you<00:08:42.169> a<00:08:42.200> block<00:08:42.500> number<00:08:42.830> that<00:08:43.040> you<00:08:43.160> can<00:08:43.310> log 00:08:43.540 --> 00:08:43.550 align:start position:0% give you a block number that you can log 00:08:43.550 --> 00:08:46.000 align:start position:0% give you a block number that you can log and<00:08:43.790> so<00:08:44.660> in<00:08:44.780> this<00:08:44.900> in<00:08:45.230> this<00:08:45.350> little<00:08:45.620> program 00:08:46.000 --> 00:08:46.010 align:start position:0% and so in this in this little program 00:08:46.010 --> 00:08:47.830 align:start position:0% and so in this in this little program we'll<00:08:46.220> just<00:08:46.460> subscribe<00:08:47.090>

balance off you want to say<00:08:53.780> which<00:08:54.050> address 00:08:54.580 --> 00:08:54.590 align:start position:0% say which address 00:08:54.590 --> 00:08:56.830 align:start position:0% say which address want<00:08:54.740> to<00:08:54.800> see<00:08:54.920> the<00:08:55.040> balance<00:08:55.310> off<00:08:55.550> and<00:08:55.850> then<00:08:56.570> I 00:08:56.830 --> 00:08:56.840 align:start position:0% want to see the balance off and then I 00:08:56.840 --> 00:08:59.470 align:start position:0% want to see the balance off and then I don't<00:08:57.140> know<00:08:57.200>

position:0% know how to use reactive or rxjs but basically<00:09:03.590> you<00:09:03.770> can<00:09:04.030> get<00:09:05.030> what's<00:09:05.390> the<00:09:05.900> result 00:09:06.220 --> 00:09:06.230 align:start position:0% basically you can get what's the result 00:09:06.230 --> 00:09:07.990 align:start position:0% basically you can get what's the result of<00:09:06.440> balance<00:09:06.800> off<00:09:07.040> and<00:09:07.280> pipe<00:09:07.550> it<00:09:07.730> and<00:09:07.940> do 00:09:07.990 --> 00:09:08.000 align:start position:0% of balance off and pipe it and do 00:09:08.000 --> 00:09:12.040 align:start position:0% of balance off and pipe it and do something<00:09:08.420> with<00:09:08.600> this<00:09:08.770> with<00:09:09.770> this<00:09:10.240> result<00:09:11.240> so 00:09:12.040 --> 00:09:12.050 align:start position:0% something with this with this result so 00:09:12.050 --> 00:09:13.450 align:start position:0% something with this with this result so what<00:09:12.440> we're<00:09:12.590> going<00:09:12.710> to<00:09:12.770> do<00:09:12.920> is<00:09:13.070> this<00:09:13.250> balance 00:09:13.450 --> 00:09:13.460 align:start position:0% what we're going to do is this balance 00:09:13.460 --> 00:09:15.100 align:start position:0% what we're going to do is this balance is<00:09:13.760> going<00:09:13.880> to<00:09:14.000> be<00:09:14.060> formatted<00:09:14.360> or<00:09:14.840> you<00:09:14.960> have<00:09:15.080> a 00:09:15.100 --> 00:09:15.110 align:start position:0% is going to be formatted or you have a 00:09:15.110 --> 00:09:20.380 align:start position:0% is going to be formatted or you have a question<00:09:18.430> so<00:09:19.430> the<00:09:19.670> question<00:09:19.700> is<00:09:20.150> well 00:09:20.380 --> 00:09:20.390 align:start position:0% question so the question is well 00:09:20.390 --> 00:09:22.990 align:start position:0% question so the question is well balanced<00:09:20.720> off<00:09:20.930> will<00:09:21.200> be<00:09:21.500> actually<00:09:21.920> stream<00:09:22.820> and 00:09:22.990 --> 00:09:23.000 align:start position:0% balanced off will be actually stream and 00:09:23.000 --> 00:09:25.840 align:start position:0% balanced off will be actually stream and updated<00:09:23.450> and<00:09:23.570> the<00:09:23.840> answer<00:09:24.200> is<00:09:24.320> yes<00:09:24.470> and<00:09:24.850> this 00:09:25.840 --> 00:09:25.850 align:start position:0% updated and the answer is yes and this 00:09:25.850 --> 00:09:27.910 align:start position:0% updated and the answer is yes and this is<00:09:26.030> the<00:09:26.210> nice<00:09:26.390> thing<00:09:26.420> without<00:09:26.920> observables 00:09:27.910 --> 00:09:27.920 align:start position:0% is the nice thing without observables 00:09:27.920 --> 00:09:30.370 align:start position:0% is the nice thing without observables and<00:09:28.130> and<00:09:28.430> your<00:09:29.030> you'll<00:09:29.630> see<00:09:29.810> that<00:09:29.930> in<00:09:30.110> your<00:09:30.230> in 00:09:30.370 --> 00:09:30.380 align:start position:0% and and your you'll see that in your in 00:09:30.380 --> 00:09:33.310 align:start position:0% and and your you'll see that in your in a<00:09:30.440> second<00:09:30.800> so<00:09:31.340> the<00:09:32.090> balance<00:09:32.420> off<00:09:32.630> will<00:09:32.870> be<00:09:32.900> you 00:09:33.310 --> 00:09:33.320 align:start position:0% a second so the balance off will be you 00:09:33.320 --> 00:09:35.320 align:start position:0% a second so the balance off will be you know<00:09:33.440> not<00:09:33.650> formatted<00:09:34.280> nicely<00:09:34.430> so<00:09:34.970> what<00:09:35.210> we 00:09:35.320 --> 00:09:35.330 align:start position:0% know not formatted nicely so what we 00:09:35.330 --> 00:09:37.090 align:start position:0% know not formatted nicely so what we want<00:09:35.480> to<00:09:35.540> do<00:09:35.660> is<00:09:35.840> from<00:09:36.140> way<00:09:36.320> we<00:09:36.530> want<00:09:36.740> to<00:09:36.800> format 00:09:37.090 --> 00:09:37.100 align:start position:0% want to do is from way we want to format 00:09:37.100 --> 00:09:40.390 align:start position:0% want to do is from way we want to format it<00:09:37.340> basically<00:09:37.760> and<00:09:38.060> then<00:09:38.860> what<00:09:39.860> we<00:09:40.010> do<00:09:40.160> is<00:09:40.280> we 00:09:40.390 --> 00:09:40.400 align:start position:0% it basically and then what we do is we 00:09:40.400 --> 00:09:42.460 align:start position:0% it basically and then what we do is we do<00:09:40.520> the<00:09:40.670> same<00:09:40.850> as<00:09:40.910> before<00:09:41.360> we<00:09:41.840> subscribe<00:09:42.290> to 00:09:42.460 --> 00:09:42.470 align:start position:0% do the same as before we subscribe to 00:09:42.470 --> 00:09:44.890 align:start position:0% do the same as before we subscribe to this<00:09:42.620> and<00:09:42.950> we<00:09:43.400> just<00:09:43.640> log<00:09:43.850> it<00:09:44.000> so<00:09:44.450> what<00:09:44.570> happens 00:09:44.890 --> 00:09:44.900 align:start position:0% this and we just log it so what happens 00:09:44.900 --> 00:09:48.520 align:start position:0% this and we just log it so what happens is<00:09:45.140> when<00:09:45.620> you<00:09:45.740> just<00:09:45.770> run<00:09:46.220> this<00:09:46.960> in<00:09:47.960> the<00:09:48.140> console 00:09:48.520 --> 00:09:48.530 align:start position:0% is when you just run this in the console 00:09:48.530 --> 00:09:51.550 align:start position:0% is when you just run this in the console it<00:09:48.890> will<00:09:49.070> just<00:09:49.280> go<00:09:50.090> like<00:09:50.270> this<00:09:50.480> current<00:09:51.350> block 00:09:51.550 --> 00:09:51.560 align:start position:0% it will just go like this current block 00:09:51.560 --> 00:09:54.310 align:start position:0% it will just go like this current block blah<00:09:52.130> blah<00:09:52.310> blah<00:09:52.520> my<00:09:52.760> balance<00:09:53.150> and<00:09:53.390> then<00:09:54.170> it 00:09:54.310 --> 00:09:54.320 align:start position:0% blah blah blah my balance and then it 00:09:54.320 --> 00:09:56.980 align:start position:0% blah blah blah my balance and then it updates<00:09:54.500> and<00:09:54.980> then<00:09:55.940> it<00:09:56.060> updates<00:09:56.270> you<00:09:56.720> change 00:09:56.980 --> 00:09:56.990 align:start position:0% updates and then it updates you change 00:09:56.990 --> 00:09:59.140 align:start position:0% updates and then it updates you change the<00:09:57.170> balance<00:09:57.320> boom<00:09:57.740> balance<00:09:58.490> will<00:09:58.700> show<00:09:58.910> the 00:09:59.140 --> 00:09:59.150 align:start position:0% the balance boom balance will show the 00:09:59.150 --> 00:10:01.210 align:start position:0% the balance boom balance will show the new<00:09:59.300> balance<00:09:59.540> and<00:09:59.900> then<00:10:00.080> it<00:10:00.230> updates<00:10:00.590> and<00:10:00.890> it 00:10:01.210 --> 00:10:01.220 align:start position:0% new balance and then it updates and it 00:10:01.220 --> 00:10:03.510 align:start position:0% new balance and then it updates and it goes<00:10:01.430> on<00:10:01.640> so<00:10:01.970> this<00:10:02.150> is<00:10:02.300> an<00:10:02.420> observable<00:10:02.900> and 00:10:03.510 --> 00:10:03.520 align:start position:0% goes on so this is an observable and 00:10:03.520 --> 00:10:06.970 align:start position:0% goes on so this is an observable and well<00:10:04.520> yeah<00:10:04.880> that's<00:10:05.180> or<00:10:05.600> XJS<00:10:06.230> like<00:10:06.500> this<00:10:06.680> is<00:10:06.830> not 00:10:06.970 --> 00:10:06.980 align:start position:0% well yeah that's or XJS like this is not 00:10:06.980 --> 00:10:09.220 align:start position:0% well yeah that's or XJS like this is not what<00:10:07.220> we<00:10:07.430> built<00:10:07.760> this<00:10:08.000> specifically<00:10:08.900> we<00:10:09.050> just 00:10:09.220 --> 00:10:09.230 align:start position:0% what we built this specifically we just 00:10:09.230 --> 00:10:10.750 align:start position:0% what we built this specifically we just built<00:10:09.440> on<00:10:09.530> top<00:10:09.710> of<00:10:09.770> this<00:10:09.980> and<00:10:10.190> and<00:10:10.430> this<00:10:10.610> is 00:10:10.750 --> 00:10:10.760 align:start position:0% built on top of this and and this is 00:10:10.760 --> 00:10:16.260 align:start position:0% built on top of this and and this is awesome<00:10:11.060> that's<00:10:11.270> why<00:10:11.390> we<00:10:11.570> will<00:10:12.080> use<00:10:12.230> it<00:10:14.830> so 00:10:16.260 --> 00:10:16.270 align:start position:0% awesome that's why we will use it so 00:10:16.270 --> 00:10:19.660 align:start position:0% awesome that's why we will use it so like<00:10:17.270> Jess<00:10:17.540> I<00:10:17.690> said<00:10:17.900> is<00:10:18.020> right<00:10:18.310> it's<00:10:19.310> actually 00:10:19.660 --> 00:10:19.670 align:start position:0% like Jess I said is right it's actually 00:10:19.670 --> 00:10:22.240 align:start position:0% like Jess I said is right it's actually extremely<00:10:20.210> simple<00:10:20.870> we<00:10:21.110> did<00:10:21.320> not<00:10:21.500> go<00:10:21.920> crazy 00:10:22.240 --> 00:10:22.250 align:start position:0% extremely simple we did not go crazy 00:10:22.250 --> 00:10:23.620 align:start position:0% extremely simple we did not go crazy with<00:10:22.580> the<00:10:22.760> amount<00:10:22.970> of<00:10:23.030> thing<00:10:23.240> we<00:10:23.420> wanna 00:10:23.620 --> 00:10:23.630 align:start position:0% with the amount of thing we wanna 00:10:23.630 --> 00:10:26.890 align:start position:0% with the amount of thing we wanna support<00:10:24.260> we<00:10:24.620> actually<00:10:24.920> just<00:10:25.450> support<00:10:26.450> what<00:10:26.750> we 00:10:26.890 --> 00:10:26.900 align:start position:0% support we actually just support what we 00:10:26.900 --> 00:10:29.590 align:start position:0% support we actually just support what we need<00:10:27.140> and<00:10:27.350> what<00:10:27.800> the<00:10:28.160> community<00:10:28.370> up<00:10:29.120> to<00:10:29.450> now 00:10:29.590 --> 00:10:29.600 align:start position:0% need and what the community up to now 00:10:29.600 --> 00:10:32.500 align:start position:0% need and what the community up to now has<00:10:29.960> told<00:10:30.230> us<00:10:30.320> lean<00:10:30.620> it<00:10:30.800> so<00:10:31.340> we<00:10:31.880> have<00:10:32.030> twelve 00:10:32.500 --> 00:10:32.510 align:start position:0% has told us lean it so we have twelve 00:10:32.510 --> 00:10:34.360 align:start position:0% has told us lean it so we have twelve functions<00:10:33.050> and<00:10:33.350> that's<00:10:33.650> it<00:10:33.830> right<00:10:34.070> we<00:10:34.250> have 00:10:34.360 --> 00:10:34.370 align:start position:0% functions and that's it right we have 00:10:34.370 --> 00:10:36.520 align:start position:0% functions and that's it right we have like<00:10:34.610> super<00:10:34.940> basic<00:10:35.120> things<00:10:35.480> the<00:10:35.780> block<00:10:36.110> number 00:10:36.520 --> 00:10:36.530 align:start position:0% like super basic things the block number 00:10:36.530 --> 00:10:38.980 align:start position:0% like super basic things the block number you<00:10:37.400> know<00:10:37.520> you<00:10:37.580> can<00:10:37.820> post<00:10:38.030> transaction<00:10:38.420> post 00:10:38.980 --> 00:10:38.990 align:start position:0% you know you can post transaction post 00:10:38.990 --> 00:10:40.570 align:start position:0% you know you can post transaction post row<00:10:39.260> transactions<00:10:39.890> already<00:10:40.280> signed 00:10:40.570 -->

can<00:10:42.170> get<00:10:42.560> some<00:10:42.800> contracts 00:10:43.240 --> 00:10:43.250 align:start position:0% transactions you can get some contracts 00:10:43.250 --> 00:10:45.850 align:start position:0% transactions you can get some contracts you<00:10:43.370> can<00:10:43.550> get<00:10:43.760> you<00:10:44.060> know<00:10:44.090> like<00:10:44.450> my<00:10:45.170> balance<00:10:45.590> the 00:10:45.850 --> 00:10:45.860 align:start position:0% you can get you know like my balance the 00:10:45.860 --> 00:10:47.470 align:start position:0% you can get you know like my balance the version<00:10:46.250> info<00:10:46.520> of<00:10:46.640> the<00:10:46.670> node<00:10:46.940> and<00:10:47.180> suffering 00:10:47.470 --> 00:10:47.480 align:start position:0% version info of the node and suffering 00:10:47.480 --> 00:10:51.400 align:start position:0% version info of the node and suffering this<00:10:48.370> so<00:10:49.370> just<00:10:49.700> to<00:10:49.820> see<00:10:49.970> an<00:10:50.750> overview<00:10:51.080> of<00:10:51.290> the 00:10:51.400 --> 00:10:51.410 align:start position:0% this so just to see an overview of the 00:10:51.410 --> 00:10:53.140 align:start position:0% this so just to see an overview of the differences<00:10:51.890> between<00:10:52.070> for<00:10:52.490> instance<00:10:52.520> web 00:10:53.140 --> 00:10:53.150

because of this we you know probably<00:13:18.569> parity<00:13:19.230> has 00:13:20.180 --> 00:13:20.190 align:start position:0% probably parity has 00:13:20.190 --> 00:13:23.750 align:start
