00:01:19.350 --> 00:01:19.360 align:start position:0%
worth a bit more now um and uh I thought
 

00:01:19.360 --> 00:01:21.310 align:start position:0%
worth a bit more now um and uh I thought
well<00:01:19.680><c> why</c><00:01:19.799><c> don't</c><00:01:20.040><c> I</c><00:01:20.640><c> why</c><00:01:21.000><c> wouldn't</c><00:01:21.200><c> The</c>

00:01:21.310 --> 00:01:21.320 align:start position:0%
well why don't I why wouldn't The
 

00:01:21.320 --> 00:01:22.590 align:start position:0%
well why don't I why wouldn't The
decentralized<00:01:21.840><c> Exchange</c><00:01:22.159><c> be</c><00:01:22.280><c> great</c><00:01:22.400><c> we</c><00:01:22.520><c> got</c>

00:01:22.590 --> 00:01:22.600 align:start position:0%
decentralized Exchange be great we got
 

00:01:22.600 --> 00:01:24.590 align:start position:0%
decentralized Exchange be great we got
this<00:01:22.720><c> decentralized</c><00:01:23.360><c> currency</c><00:01:24.240><c> but</c><00:01:24.320><c> we</c><00:01:24.479><c> got</c>

00:01:24.590 --> 00:01:24.600 align:start position:0%
this decentralized currency but we got
 

00:01:24.600 --> 00:01:26.230 align:start position:0%
this decentralized currency but we got
these<00:01:24.799><c> centralized</c><00:01:25.560><c> this</c><00:01:25.759><c> centralized</c>

00:01:26.230 --> 00:01:26.240 align:start position:0%
these centralized this centralized
 

00:01:26.240 --> 00:01:28.429 align:start position:0%
these centralized this centralized
infrastructure<00:01:27.079><c> so</c><00:01:27.200><c> I</c><00:01:27.320><c> looked</c><00:01:27.520><c> into</c><00:01:27.759><c> doing</c><00:01:28.280><c> a</c>

00:01:28.429 --> 00:01:28.439 align:start position:0%
infrastructure so I looked into doing a
 

00:01:28.439 --> 00:01:30.230 align:start position:0%
infrastructure so I looked into doing a
decentralized<00:01:29.040><c> exchange</c><00:01:29.360><c> and</c><00:01:29.479><c> just</c><00:01:29.600><c> for</c><00:01:29.960><c> is</c><00:01:30.040><c> a</c>

00:01:30.230 --> 00:01:30.240 align:start position:0%
decentralized exchange and just for is a
 

00:01:30.240 --> 00:01:33.149 align:start position:0%
decentralized exchange and just for is a
sort<00:01:30.400><c> of</c><00:01:30.600><c> interesting</c><00:01:31.600><c> um</c><00:01:31.799><c> thought</c><00:01:32.159><c> project</c>

00:01:33.149 --> 00:01:33.159 align:start position:0%
sort of interesting um thought project
 

00:01:33.159 --> 00:01:37.149 align:start position:0%
sort of interesting um thought project
um<00:01:33.720><c> wondered</c><00:01:34.200><c> what</c><00:01:34.360><c> a</c><00:01:34.640><c> back</c><00:01:34.840><c> end</c><00:01:35.280><c> might</c><00:01:35.479><c> be</c>

00:01:37.149 --> 00:01:37.159 align:start position:0%
um wondered what a back end might be
 

00:01:37.159 --> 00:01:39.630 align:start position:0%
um wondered what a back end might be
like

00:01:39.630 --> 00:01:39.640 align:start position:0%
like
 

00:01:39.640 --> 00:01:43.069 align:start position:0%
like
um<00:01:40.640><c> when</c><00:01:40.880><c> I</c><00:01:41.799><c> considered</c><00:01:42.320><c> how</c><00:01:42.479><c> it</c><00:01:42.720><c> might</c><00:01:42.880><c> be</c>

00:01:43.069 --> 00:01:43.079 align:start position:0%
um when I considered how it might be
 

00:01:43.079 --> 00:01:45.469 align:start position:0%
um when I considered how it might be
implemented<00:01:44.079><c> um</c><00:01:44.479><c> immediately</c><00:01:45.000><c> of</c><00:01:45.119><c> course</c><00:01:45.360><c> I</c>

00:01:45.469 --> 00:01:45.479 align:start position:0%
implemented um immediately of course I
 

00:01:45.479 --> 00:01:48.709 align:start position:0%
implemented um immediately of course I
thought<00:01:45.719><c> about</c><00:01:46.680><c> uh</c><00:01:47.240><c> what</c><00:01:47.520><c> abstraction</c><00:01:48.520><c> this</c>

00:01:48.709 --> 00:01:48.719 align:start position:0%
thought about uh what abstraction this
 

00:01:48.719 --> 00:01:51.030 align:start position:0%
thought about uh what abstraction this
was<00:01:49.200><c> what</c><00:01:49.399><c> what</c><00:01:49.719><c> you</c><00:01:49.799><c> know</c><00:01:50.040><c> underneath</c>

00:01:51.030 --> 00:01:51.040 align:start position:0%
was what what you know underneath
 

00:01:51.040 --> 00:01:52.630 align:start position:0%
was what what you know underneath
underneath<00:01:51.520><c> the</c><00:01:51.680><c> application</c><00:01:52.360><c> what</c><00:01:52.479><c> was</c>

00:01:52.630 --> 00:01:52.640 align:start position:0%
underneath the application what was
 

00:01:52.640 --> 00:01:54.270 align:start position:0%
underneath the application what was
really<00:01:52.920><c> going</c><00:01:53.159><c> on</c><00:01:53.439><c> and</c><00:01:53.680><c> and</c><00:01:53.960><c> is</c><00:01:54.079><c> there</c><00:01:54.159><c> a</c>

00:01:54.270 --> 00:01:54.280 align:start position:0%
really going on and and is there a
 

00:01:54.280 --> 00:01:55.910 align:start position:0%
really going on and and is there a

00:01:55.910 --> 00:01:55.920 align:start position:0%

00:02:28.150 --> 00:02:28.160 align:start position:0%
what what what I'm going to describe to
 

00:02:28.160 --> 00:02:30.309 align:start position:0%
what what what I'm going to describe to
you<00:02:28.280><c> now</c><00:02:28.400><c> and</c><00:02:28.480><c> it</c><00:02:28.560><c> would</c><00:02:28.720><c> use</c><00:02:28.959><c> web</c><00:02:29.120><c> RTC</c><00:02:29.599><c> in</c><00:02:30.040><c> to</c>

00:02:30.309 --> 00:02:30.319 align:start position:0%
you now and it would use web RTC in to
 

00:02:30.319 --> 00:02:32.750 align:start position:0%
you now and it would use web RTC in to
connect<00:02:30.599><c> all</c><00:02:30.720><c> the</c><00:02:30.840><c> nodes</c><00:02:31.519><c> together</c><00:02:32.519><c> so</c>

00:02:32.750 --> 00:02:32.760 align:start position:0%
connect all the nodes together so
 

00:02:32.760 --> 00:02:34.070 align:start position:0%
connect all the nodes together so
basically<00:02:33.120><c> you'd</c><00:02:33.319><c> end</c><00:02:33.440><c> up</c><00:02:33.560><c> with</c><00:02:33.680><c> a</c><00:02:33.800><c> web</c>

00:02:34.070 --> 00:02:34.080 align:start position:0%
basically you'd end up with a web
 

00:02:34.080 --> 00:02:37.070 align:start position:0%
basically you'd end up with a web
experience<00:02:34.640><c> but</c><00:02:34.760><c> it</c><00:02:34.840><c> would</c><00:02:35.040><c> be</c><00:02:35.800><c> um</c><00:02:36.560><c> an</c><00:02:36.720><c> entire</c>

00:02:37.070 --> 00:02:37.080 align:start position:0%

00:12:39.509 --> 00:12:39.519 align:start position:0%

so<00:12:40.519><c> is</c><00:12:40.639><c> it</c><00:12:40.880><c> is</c><00:12:40.959><c> it</c><00:12:41.079><c> a</c><00:12:41.199><c> DHD</c><00:12:41.720><c> is</c><00:12:41.800><c> it</c><00:12:41.920><c> a</c><00:12:42.040><c> distributed</c>

00:12:48.110 --> 00:12:48.120 align:start position:0%
treat it as a DHT what we can say is
 

00:12:48.120 --> 00:12:51.230 align:start position:0%
treat it as a DHT what we can say is
it's<00:12:48.240><c> a</c><00:12:48.360><c> multi-</c><00:12:48.720><c> key</c><00:12:49.040><c> DHD</c><00:12:50.040><c> which</c><00:12:50.160><c> is</c><00:12:50.360><c> to</c><00:12:50.600><c> say</c>

00:12:51.230 --> 00:12:51.240 align:start position:0%
it's a multi- key DHD which is to say
 

00:12:51.240 --> 00:12:53.829 align:start position:0%
it's a multi- key DHD which is to say
each<00:12:51.560><c> entry</c><00:12:52.320><c> in</c><00:12:52.480><c> the</c><00:12:52.639><c> hash</c><00:12:52.880><c> table</c><00:12:53.519><c> doesn't</c>

00:12:53.829 --> 00:12:53.839 align:start position:0%
each entry in the hash table doesn't
 

00:12:53.839 --> 00:12:56.590 align:start position:0%
each entry in the hash table doesn't
just<00:12:54.000><c> have</c><00:12:54.120><c> one</c><00:12:54.320><c> key</c><00:12:54.519><c> it</c><00:12:54.600><c> has</c><00:12:54.760><c> many</c><00:12:55.120><c> keys</c><00:12:56.120><c> okay</c>

00:12:56.590 --> 00:12:56.600 align:start position:0%
just have one key it has many keys okay
 

00:12:56.600 --> 00:12:59.590 align:start position:0%
just have one key it has many keys okay
so<00:12:56.760><c> it's</c><00:12:56.920><c> like</c><00:12:57.040><c> a</c><00:12:57.240><c> composite</c><00:12:58.120><c> key</c><00:12:59.199><c> it</c><00:12:59.279><c> can</c><00:12:59.399><c> have</c>

00:12:59.590 --> 00:12:59.600 align:start position:0%
so it's like a composite key it can have
 

00:12:59.600 --> 00:13:01.269 align:start position:0%
so it's like a composite key it can have

um<00:24:23.360><c> so</c><00:24:24.360><c> we</c><00:24:24.480><c> can</c><00:24:24.640><c> either</c><00:24:24.840><c> do</c><00:24:24.960><c> it</c><00:24:25.080><c> passively</c><00:24:25.440><c> or</c>

00:24:25.590 --> 00:24:25.600 align:start position:0%
um so we can either do it passively or
 

00:24:25.600 --> 00:24:27.110 align:start position:0%
um so we can either do it passively or
actively<00:24:26.000><c> if</c><00:24:26.120><c> we</c><00:24:26.200><c> do</c><00:24:26.320><c> it</c><00:24:26.440><c> passively</c><00:24:26.840><c> we</c><00:24:26.960><c> give</c>

00:24:27.110 --> 00:24:27.120 align:start position:0%
actively if we do it passively we give
 

00:24:27.120 --> 00:24:29.190 align:start position:0%
actively if we do it passively we give

Smiley kittens so um what I uh what we
 

00:27:28.919 --> 00:27:31.669 align:start position:0%
Smiley kittens so um what I uh what we
then<00:27:29.120><c> do</c><00:27:29.679><c> is</c><00:27:29.799><c> we</c><00:27:29.960><c> form</c><00:27:30.200><c> a</c><00:27:30.399><c> mask</c><00:27:30.840><c> now</c><00:27:30.960><c> a</c><00:27:31.080><c> mask</c><00:27:31.399><c> is</c>

00:27:31.669 --> 00:27:31.679 align:start position:0%
then do is we form a mask now a mask is
 

00:27:31.679 --> 00:27:33.110 align:start position:0%
then do is we form a mask now a mask is
is<00:27:31.840><c> just</c><00:27:32.000><c> another</c><00:27:32.320><c> one</c><00:27:32.440><c> of</c><00:27:32.600><c> these</c><00:27:32.760><c> things</c><00:27:32.960><c> it's</c>

00:27:33.110 --> 00:27:33.120 align:start position:0%
is just another one of these things it's
 

00:27:33.120 --> 00:27:37.909 align:start position:0%
is just another one of these things it's
another<00:27:33.480><c> 32</c><00:27:34.039><c> bit</c><00:27:34.559><c> 32bit</c><00:27:35.559><c> um</c><00:27:36.120><c> series</c><00:27:37.120><c> um</c><00:27:37.640><c> it's</c>

00:27:37.909 --> 00:27:37.919 align:start position:0%
another 32 bit 32bit um series um it's
 

00:27:37.919 --> 00:27:41.149 align:start position:0%
another 32 bit 32bit um series um it's
mostly<00:27:38.440><c> zeros</c><00:27:39.159><c> so</c><00:27:39.360><c> it's</c><00:27:39.520><c> like</c><00:27:39.720><c> z</c><00:27:40.080><c> z</c><00:27:40.360><c> z</c><00:27:40.679><c> z</c><00:27:41.039><c> and</c>

00:27:41.149 --> 00:27:41.159 align:start position:0%
mostly zeros so it's like z z z z and
 

00:27:41.159 --> 00:27:42.990 align:start position:0%
mostly zeros so it's like z z z z and
then<00:27:41.279><c> maybe</c><00:27:41.519><c> a</c><00:27:41.679><c> one</c><00:27:41.919><c> and</c><00:27:42.000><c> then</c><00:27:42.159><c> lots</c><00:27:42.320><c> of</c><00:27:42.519><c> zeros</c>

00:27:42.990 --> 00:27:43.000 align:start position:0%
then maybe a one and then lots of zeros
 

00:27:43.000 --> 00:27:44.830 align:start position:0%
then maybe a one and then lots of zeros
and<00:27:43.120><c> maybe</c><00:27:43.360><c> another</c><00:27:43.640><c> one</c><00:27:43.840><c> and</c><00:27:44.000><c> zero</c><00:27:44.559><c> and</c><00:27:44.720><c> all</c>

00:27:44.830 --> 00:27:44.840 align:start position:0%
and maybe another one and zero and all
 

00:27:44.840 --> 00:27:47.430 align:start position:0%
and maybe another one and zero and all
the<00:27:44.960><c> rest</c><00:27:45.159><c> Z</c><00:27:45.840><c> and</c><00:27:46.000><c> what</c><00:27:46.120><c> this</c><00:27:46.240><c> does</c><00:27:46.399><c> is</c><00:27:46.519><c> it</c><00:27:46.640><c> says</c>

00:27:47.430 --> 00:27:47.440 align:start position:0%
the rest Z and what this does is it says
 

00:27:47.440 --> 00:27:50.470 align:start position:0%
the rest Z and what this does is it says
ignore<00:27:47.960><c> these</c><00:27:48.440><c> bits</c><00:27:49.440><c> so</c><00:27:49.720><c> these</c><00:27:49.960><c> now</c><00:27:50.120><c> get</c><00:27:50.279><c> set</c>

00:27:50.470 --> 00:27:50.480 align:start position:0%
ignore these bits so these now get set
 

00:27:50.480 --> 00:27:56.630 align:start position:0%
ignore these bits so these now get set
to<00:27:50.960><c> zero</c><00:27:51.960><c> right</c><00:27:52.799><c> we</c><00:27:53.399><c> we</c><00:27:53.600><c> we</c><00:27:53.799><c> multiply</c><00:27:54.840><c> them</c><00:27:55.840><c> um</c>

00:27:56.630 --> 00:27:56.640 align:start position:0%
to zero right we we we multiply them um
 

00:27:56.640 --> 00:27:58.710 align:start position:0%
to zero right we we we multiply them um
but<00:27:56.799><c> we</c><00:27:57.000><c> ignore</c><00:27:57.640><c> but</c><00:27:57.760><c> what</c><00:27:57.840><c> we</c><00:27:57.919><c> do</c><00:27:58.279><c> is</c><00:27:58.360><c> we</c><00:27:58.480><c> don't</c>

00:27:58.710 --> 00:27:58.720 align:start position:0%
but we ignore but what we do is we don't
 

00:27:58.720 --> 00:28:01.990 align:start position:0%
but we ignore but what we do is we don't
multiply<00:27:59.159><c> the</c><00:27:59.279><c> ones</c><00:27:59.640><c> that</c><00:27:59.760><c> are</c><00:28:00.120><c> above</c><00:28:01.039><c> a</c><00:28:01.279><c> one</c>

00:28:01.990 --> 00:28:02.000 align:start position:0%
multiply the ones that are above a one
 

00:28:02.000 --> 00:28:04.389 align:start position:0%
multiply the ones that are above a one
okay<00:28:02.720><c> so</c><00:28:02.960><c> now</c><00:28:03.159><c> all</c><00:28:03.320><c> of</c><00:28:03.440><c> these</c><00:28:03.559><c> are</c>

00:28:04.389 --> 00:28:04.399 align:start position:0%
okay so now all of these are
 

00:28:04.399 --> 00:28:08.070 align:start position:0%
okay so now all of these are
zeros<00:28:05.399><c> bit</c><00:28:05.600><c> wise</c><00:28:06.320><c> multiply</c><00:28:07.320><c> except</c><00:28:07.600><c> for</c><00:28:07.799><c> these</c>

00:28:08.070 --> 00:28:08.080 align:start position:0%
zeros bit wise multiply except for these
 

00:28:08.080 --> 00:28:09.990 align:start position:0%
zeros bit wise multiply except for these
and<00:28:08.200><c> we</c><00:28:08.399><c> provide</c><00:28:08.840><c> both</c><00:28:09.039><c> of</c><00:28:09.240><c> these</c><00:28:09.720><c> so</c><00:28:09.880><c> what</c>

00:28:09.990 --> 00:28:10.000 align:start position:0%
and we provide both of these so what
 

00:28:10.000 --> 00:28:11.990 align:start position:0%
and we provide both of these so what
we're<00:28:10.200><c> doing</c><00:28:10.480><c> is</c><00:28:10.600><c> we're</c><00:28:10.880><c> hiding</c><00:28:11.440><c> most</c><00:28:11.640><c> of</c><00:28:11.840><c> the</c>

00:28:11.990 --> 00:28:12.000 align:start position:0%
we're doing is we're hiding most of the
 

00:28:12.000 --> 00:28:13.310 align:start position:0%
we're doing is we're hiding most of the
information<00:28:12.600><c> because</c><00:28:12.720><c> they're</c><00:28:12.919><c> all</c><00:28:13.159><c> they're</c>

00:28:13.310 --> 00:28:13.320 align:start position:0%
information because they're all they're
 

00:28:13.320 --> 00:28:14.669 align:start position:0%

00:28:14.669 --> 00:28:14.679 align:start position:0%
all set to zero so it's like getting a
 

00:28:14.679 --> 00:28:16.789 align:start position:0%
all set to zero so it's like getting a

00:28:20.590 --> 00:28:20.600 align:start position:0%
maybe one or two of the numbers there
 

00:28:20.600 --> 00:28:21.990 align:start position:0%

00:43:00.230 --> 00:43:00.240 align:start position:0%
this is also just the
 

00:43:00.240 --> 00:43:02.790 align:start position:0%
this is also just the

00:43:02.790 --> 00:43:02.800 align:start position:0%
direction so this is this is an API
 

00:43:02.800 --> 00:43:04.270 align:start position:0%
direction so this is this is an API
right<00:43:03.000><c> this</c><00:43:03.200><c> what</c><00:43:03.319><c> this</c><00:43:03.440><c> isn't</c><00:43:03.720><c> is</c><00:43:03.880><c> the</c><00:43:04.000><c> wire</c>

00:43:04.270 --> 00:43:04.280 align:start position:0%
right this what this isn't is the wire
 

00:43:04.280 --> 00:43:06.390 align:start position:0%
right this what this isn't is the wire

00:43:08.200 --> 00:43:10.030 align:start position:0%
from and through so what's what's it
using<00:43:08.480><c> it</c><00:43:08.640><c> for</c><00:43:08.880><c> it's</c><00:43:09.079><c> just</c><00:43:09.240><c> the</c><00:43:09.400><c> encryption</c>

00:43:10.030 --> 00:43:10.040 align:start position:0%
using it for it's just the encryption
 

00:43:10.040 --> 00:43:13.470 align:start position:0%
using it for it's just the encryption
exactly<00:43:10.920><c> encryption</c><00:43:11.359><c> and</c><00:43:11.839><c> signing</c><00:43:12.839><c> so</c><00:43:13.240><c> is</c><00:43:13.319><c> it</c>

00:43:13.470 --> 00:43:13.480 align:start position:0%
exactly encryption and signing so is it
 

00:43:13.480 --> 00:43:15.790 align:start position:0%
exactly encryption and signing so is it
possible<00:43:13.720><c> to</c><00:43:13.920><c> send</c><00:43:14.319><c> to</c><00:43:14.599><c> the</c><00:43:14.800><c> subset</c><00:43:15.240><c> of</c><00:43:15.440><c> people</c>

00:43:15.790 --> 00:43:15.800 align:start position:0%
possible to send to the subset of people
 

00:43:15.800 --> 00:43:18.510 align:start position:0%
possible to send to the subset of people
so<00:43:16.119><c> several</c><00:43:16.640><c> public</c><00:43:17.040><c> you</c><00:43:17.200><c> send</c><00:43:17.400><c> to</c><00:43:17.599><c> everybody</c>

00:43:18.510 --> 00:43:18.520 align:start position:0%
so several public you send to everybody
 

00:43:18.520 --> 00:43:20.670 align:start position:0%
so several public you send to everybody
uh<00:43:18.640><c> so</c><00:43:18.880><c> multicasting</c><00:43:19.720><c> indeed</c><00:43:20.319><c> so</c><00:43:20.520><c> for</c>

uh so multicasting indeed so for

advance in a large range of topics and
 

00:45:23.880 --> 00:45:26.630 align:start position:0%
advance in a large range of topics and
then<00:45:24.319><c> you</c><00:45:24.559><c> send</c><00:45:25.040><c> to</c><00:45:25.200><c> a</c><00:45:25.359><c> square</c><00:45:25.680><c> root</c><00:45:26.000><c> of</c><00:45:26.240><c> those</c>

00:45:26.630 --> 00:45:26.640 align:start position:0%
then you send to a square root of those
 

00:45:26.640 --> 00:45:29.510 align:start position:0%
then you send to a square root of those

00:45:29.510 --> 00:45:29.520 align:start position:0%
of that range and they have search in a
 

00:45:29.520 --> 00:45:32.069 align:start position:0%
of that range and they have search in a

square in a different random square root
 

00:45:32.079 --> 00:45:34.470 align:start position:0%
square in a different random square root

00:45:34.470 --> 00:45:34.480 align:start position:0%
and then one of those messages will be
 

00:45:34.480 --> 00:45:37.190 align:start position:0%
and then one of those messages will be
there<00:45:35.079><c> so</c><00:45:35.400><c> the</c><00:45:35.920><c> external</c><00:45:36.359><c> Observer</c><00:45:36.839><c> has</c><00:45:36.960><c> no</c>

00:45:37.190 --> 00:45:37.200 align:start position:0%
there so the external Observer has no
 

00:45:37.200 --> 00:45:39.309 align:start position:0%
there so the external Observer has no

00:45:39.309 --> 00:45:39.319 align:start position:0%
chance so following from that there is
 

00:45:39.319 --> 00:45:40.990 align:start position:0%

00:45:40.990 --> 00:45:41.000 align:start position:0%
actually a protocol that I came up with
 

00:45:41.000 --> 00:45:43.790 align:start position:0%
actually a protocol that I came up with

00:45:43.790 --> 00:45:43.800 align:start position:0%

that allows a um this to so the basic

what it means at all and so obviously
 

00:46:41.280 --> 00:46:42.790 align:start position:0%
what it means at all and so obviously
that<00:46:41.440><c> can</c><00:46:41.559><c> then</c><00:46:41.680><c> be</c><00:46:41.880><c> probabilistically</c>

00:46:42.790 --> 00:46:42.800 align:start position:0%
that can then be probabilistically

this for high frequency tring I
 

00:49:24.319 --> 00:49:26.910 align:start position:0%
this for high frequency tring I
think<00:49:25.319><c> uh</c><00:49:25.640><c> I</c><00:49:25.720><c> mean</c><00:49:26.000><c> it's</c><00:49:26.160><c> true</c><00:49:26.400><c> but</c><00:49:26.599><c> the</c><00:49:26.799><c> the</c>

00:49:26.910 --> 00:49:26.920 align:start position:0%
think uh I mean it's true but the the
 

00:49:26.920 --> 00:49:28.190 align:start position:0%
think uh I mean it's true but the the

00:49:28.190 --> 00:49:28.200 align:start position:0%
question is how much is there to be

you're aiming for every message to be

00:49:59.630 --> 00:49:59.640 align:start position:0%

00:49:59.640 --> 00:50:02.390 align:start position:0%
broadcast at every node but that will
never<00:50:00.240><c> happen</c><00:50:01.240><c> yeah</c><00:50:01.640><c> yeah</c><00:50:01.920><c> at</c><00:50:02.040><c> least</c><00:50:02.200><c> not</c>

00:50:02.390 --> 00:50:02.400 align:start position:0%
never happen yeah yeah at least not

it's<00:50:05.400><c> not</c><00:50:05.599><c> that</c><00:50:05.760><c> every</c><00:50:06.000><c> node</c><00:50:06.400><c> has</c><00:50:07.079><c> you</c><00:50:07.160><c> know</c>

00:50:07.349 --> 00:50:07.359 align:start position:0%
it's not that every node has you know
 

00:50:07.359 --> 00:50:08.950 align:start position:0%
it's not that every node has you know
will<00:50:07.559><c> will</c><00:50:07.760><c> have</c><00:50:08.079><c> all</c><00:50:08.400><c> information</c>

can<01:08:25.520><c> you</c><01:08:25.600><c> can</c><01:08:26.159><c> just</c><01:08:26.279><c> make</c><01:08:26.480><c> random</c><01:08:26.759><c> messages</c><01:08:27.480><c> so</c>

01:08:28.349 --> 01:08:28.359 align:start position:0%
can you can just make random messages so
 

01:08:28.359 --> 01:08:30.030 align:start position:0%
can you can just make random messages so
um<01:08:28.679><c> how</c><01:08:28.839><c> do</c><01:08:28.960><c> you</c><01:08:29.080><c> get</c><01:08:29.239><c> around</c><01:08:29.520><c> this</c><01:08:29.759><c> well</c><01:08:29.920><c> you</c>

01:08:30.030 --> 01:08:30.040 align:start position:0%
um how do you get around this well you
 

01:08:30.040 --> 01:08:33.110 align:start position:0%
um how do you get around this well you
can<01:08:30.359><c> reasonably</c><01:08:31.040><c> assume</c><01:08:31.759><c> that</c><01:08:32.440><c> uh</c><01:08:32.920><c> the</c>

01:08:33.110 --> 01:08:33.120 align:start position:0%
can reasonably assume that uh the
 

01:08:33.120 --> 01:08:35.590 align:start position:0%
can reasonably assume that uh the

peers<01:08:36.319><c> I</c><01:08:36.400><c> mean</c><01:08:36.880><c> okay</c><01:08:37.080><c> if</c><01:08:37.159><c> you</c><01:08:37.279><c> assume</c><01:08:37.560><c> all</c><01:08:37.719><c> your</c>

01:08:37.829 --> 01:08:37.839 align:start position:0%
peers I mean okay if you assume all your
 

01:08:37.839 --> 01:08:40.070 align:start position:0%
peers I mean okay if you assume all your

01:08:40.070 --> 01:08:40.080 align:start position:0%
peers are are bad then you pretty
 

01:08:40.080 --> 01:08:42.269 align:start position:0%
peers are are bad then you pretty
anyway<01:08:40.480><c> so</c><01:08:41.400><c> so</c><01:08:41.560><c> you</c><01:08:41.679><c> assume</c><01:08:41.880><c> that</c><01:08:42.000><c> the</c><01:08:42.120><c> other</c>

01:08:42.269 --> 01:08:42.279 align:start position:0%
anyway so so you assume that the other
 

01:08:42.279 --> 01:08:43.910 align:start position:0%
anyway so so you assume that the other
peers<01:08:42.520><c> are</c><01:08:42.600><c> giving</c><01:08:42.799><c> you</c><01:08:42.960><c> roughly</c><01:08:43.520><c> decent</c>

01:08:43.920 --> 01:08:44.910 align:start position:0%
