WEBVTT - A Critic of Cryptocurrencies Says Bitcoin Needs To Be Burnt With Fire

0:00:10.680 --> 0:00:14.040
<v Speaker 1>Hello, and welcome to another episode of the All Thoughts podcast.

0:00:14.120 --> 0:00:19.000
<v Speaker 1>I'm Tracy Alloway and I'm so Joe. I think at

0:00:19.000 --> 0:00:23.480
<v Speaker 1>this point we've had a number of people either involved

0:00:23.640 --> 0:00:27.200
<v Speaker 1>in the cryptocurrency boom or a massive fans of it

0:00:27.320 --> 0:00:30.240
<v Speaker 1>on the podcast. Correct, Yeah, we have now, haven't we.

0:00:30.360 --> 0:00:33.360
<v Speaker 1>I hadn't really like thought about that, but in the

0:00:33.440 --> 0:00:36.879
<v Speaker 1>last um several months, it does feel like even with

0:00:37.159 --> 0:00:39.440
<v Speaker 1>the sort of boom having waned quite a bit over

0:00:39.479 --> 0:00:41.920
<v Speaker 1>the last year, we have talked to a number of

0:00:42.520 --> 0:00:46.479
<v Speaker 1>hardcore true believers. Yes, and we've discussed this before, but

0:00:46.560 --> 0:00:49.240
<v Speaker 1>our timing on this has been absolutely terrible because we

0:00:49.320 --> 0:00:53.240
<v Speaker 1>basically waited until the bubble had burst for us to

0:00:53.280 --> 0:00:55.240
<v Speaker 1>get a bunch of bitcoin people on. But you know,

0:00:55.280 --> 0:00:57.840
<v Speaker 1>at least we didn't contribute to the bubble, because I

0:00:57.840 --> 0:01:00.720
<v Speaker 1>don't think like we did a single cryptopisode in all

0:01:00.760 --> 0:01:04.240
<v Speaker 1>of as far as I know, and so at least

0:01:04.800 --> 0:01:07.399
<v Speaker 1>when everyone was like, you know, losing their heads or

0:01:07.520 --> 0:01:09.759
<v Speaker 1>going crazy, at least we didn't at least we didn't

0:01:09.800 --> 0:01:12.880
<v Speaker 1>amplify the hype. This is very true. But I think

0:01:12.959 --> 0:01:16.199
<v Speaker 1>in the interest of fairness, at this point, we need

0:01:16.240 --> 0:01:20.360
<v Speaker 1>to get a sort of anti crypto person on and

0:01:20.480 --> 0:01:25.560
<v Speaker 1>in my search for this ultimate anti crypto person, I

0:01:25.600 --> 0:01:30.880
<v Speaker 1>think I came upon the most sort of vociferous um

0:01:31.000 --> 0:01:36.360
<v Speaker 1>argument against cryptocurrencies and also the underlying blockchain technology that

0:01:36.480 --> 0:01:38.399
<v Speaker 1>I have ever seen. Wait, are we gonna are we

0:01:38.440 --> 0:01:42.040
<v Speaker 1>talking to Jamie Diamond today? No, it's not Jamie. Jamie

0:01:42.080 --> 0:01:45.040
<v Speaker 1>Diamond was not that convincing, because you know, he came

0:01:45.080 --> 0:01:47.480
<v Speaker 1>to that conference said bitcoin was a fraud. But we

0:01:47.560 --> 0:01:49.640
<v Speaker 1>know that JP Morgan at the same time that it

0:01:49.680 --> 0:01:52.640
<v Speaker 1>says bitcoin as a fraud, claims to be experimenting with

0:01:52.680 --> 0:01:55.520
<v Speaker 1>blockchain technology. So no, no, I mean, there's a there's

0:01:55.520 --> 0:01:58.440
<v Speaker 1>a really interesting there's a really good point here, and

0:01:58.480 --> 0:02:01.360
<v Speaker 1>it's something that I've always foundrustrating in the debate Whisha

0:02:01.360 --> 0:02:05.760
<v Speaker 1>is that there's no shortage of bitcoin skeptics and Bitcoin

0:02:05.840 --> 0:02:07.720
<v Speaker 1>critics and people call it a fraud in the Ponzi

0:02:07.760 --> 0:02:10.840
<v Speaker 1>scheme in a bubble. What there is a shortage of, however,

0:02:11.320 --> 0:02:15.200
<v Speaker 1>are people who are who call bitcoin of fraud or

0:02:15.240 --> 0:02:18.119
<v Speaker 1>their skeptical of it, who have actually done the research

0:02:18.240 --> 0:02:21.359
<v Speaker 1>and have the technical chops to understand it and understand

0:02:21.360 --> 0:02:23.639
<v Speaker 1>what they're talking about. So you get all these people

0:02:23.680 --> 0:02:26.040
<v Speaker 1>on stage or they say bitcoin is a scam, it's

0:02:26.080 --> 0:02:28.960
<v Speaker 1>like okay, but when they usually don't have is anything

0:02:29.000 --> 0:02:31.800
<v Speaker 1>interesting to say after that? And so that is what

0:02:31.840 --> 0:02:35.840
<v Speaker 1>I'm absolutely what I'm hoping that maybe we can accomplish today. Absolutely,

0:02:35.840 --> 0:02:38.880
<v Speaker 1>And what you often hear from the crypto proponents is, oh, well,

0:02:39.040 --> 0:02:42.000
<v Speaker 1>you don't understand the technology, or you don't understand the

0:02:42.000 --> 0:02:45.840
<v Speaker 1>technology is potential, and so it's not worth talking to you, okay.

0:02:45.919 --> 0:02:48.760
<v Speaker 1>So I'm very pleased to say that we have found

0:02:48.800 --> 0:02:51.359
<v Speaker 1>not only a tech expert, but someone who is sort

0:02:51.400 --> 0:02:55.280
<v Speaker 1>of the ultimate anti crypto person who gave a presentation

0:02:55.440 --> 0:02:58.560
<v Speaker 1>at the Enigma Use and Next conference in California just

0:02:58.600 --> 0:03:01.400
<v Speaker 1>about a month ago. The title of this conference was

0:03:01.480 --> 0:03:06.000
<v Speaker 1>Cryptocurrencies and blockchain burn it with fire. You can't get

0:03:06.040 --> 0:03:08.680
<v Speaker 1>stronger than that, can you. So I'm very excited to

0:03:08.680 --> 0:03:11.840
<v Speaker 1>say that our guest for this episode is Nick Weaver.

0:03:12.000 --> 0:03:15.720
<v Speaker 1>He is a researcher at the International Computer Science Institute

0:03:15.840 --> 0:03:19.440
<v Speaker 1>and a lecturer at UC Berkeley. Nick, thanks so much

0:03:19.480 --> 0:03:23.440
<v Speaker 1>for coming on, Thanks for hosting me. Uh So, Nick,

0:03:24.160 --> 0:03:27.920
<v Speaker 1>I gotta say cryptocurrencies burn it with fire. You know

0:03:28.360 --> 0:03:30.720
<v Speaker 1>you're you're clearly not mincing your words here. You have

0:03:30.760 --> 0:03:36.040
<v Speaker 1>strong feelings about the crypto sphere, yes, and that's because

0:03:36.160 --> 0:03:40.880
<v Speaker 1>I've actually been able to watch it for uh three

0:03:40.960 --> 0:03:44.680
<v Speaker 1>quarters of a decade now. So what happened when the

0:03:44.800 --> 0:03:54.520
<v Speaker 1>cryptocurrencies first came out in in and is most people

0:03:54.560 --> 0:03:58.080
<v Speaker 1>who looked at it with technical understanding went, oh, this

0:03:58.160 --> 0:04:02.880
<v Speaker 1>is bovine excrement and walked away. But I have a

0:04:02.920 --> 0:04:07.839
<v Speaker 1>monetization model. I can watch the cryptocurrency space and turn

0:04:07.920 --> 0:04:12.760
<v Speaker 1>it into both academic papers and non academic papers, and

0:04:12.880 --> 0:04:16.479
<v Speaker 1>so I've been able to basically mind comedy gold from

0:04:16.520 --> 0:04:20.479
<v Speaker 1>the field for uh several years now. And that means

0:04:20.600 --> 0:04:25.640
<v Speaker 1>I've been aware from the beginning from Saga's such as

0:04:26.440 --> 0:04:29.680
<v Speaker 1>ten percent of all bitcoin being invested in a ponzi

0:04:29.760 --> 0:04:34.320
<v Speaker 1>scheme run by a guy called Pirate at forty so uh.

0:04:34.600 --> 0:04:38.800
<v Speaker 1>In your presentation and in your talks and tweeting your

0:04:38.839 --> 0:04:42.120
<v Speaker 1>critical of both sort of public block chains which is

0:04:42.120 --> 0:04:46.760
<v Speaker 1>what we call cryptocurrency, uh, and also corporate block chains.

0:04:46.920 --> 0:04:49.520
<v Speaker 1>I'm a little less interested in the corporate side because

0:04:49.560 --> 0:04:53.600
<v Speaker 1>I feel like there are very few defenders of them anymore.

0:04:54.160 --> 0:04:56.320
<v Speaker 1>And so you'll find a lot of agreement even among

0:04:56.360 --> 0:05:00.719
<v Speaker 1>cryptocurrency enthusiasts when you look at cryptocurrent these however, and

0:05:00.760 --> 0:05:03.880
<v Speaker 1>this idea of like bitcoin as this sort of permission

0:05:03.920 --> 0:05:08.880
<v Speaker 1>list kind of anonymous payment system, decentralized, what is, in

0:05:09.000 --> 0:05:12.240
<v Speaker 1>your view, the sort of fatal flaw that makes it

0:05:12.440 --> 0:05:16.479
<v Speaker 1>not live up to the hype of its advocates, the

0:05:16.560 --> 0:05:20.920
<v Speaker 1>big fatal flaws. It doesn't actually work as currency if

0:05:20.960 --> 0:05:24.560
<v Speaker 1>you can't use it as a competitor to all the

0:05:24.680 --> 0:05:32.359
<v Speaker 1>other actual digital currency systems we have, like oh, PayPal, Impassa's,

0:05:32.680 --> 0:05:37.719
<v Speaker 1>l Asa. All of these payment systems are vastly more

0:05:37.760 --> 0:05:43.520
<v Speaker 1>efficient than the cryptocurrencies, unless you're interested in criminal activity.

0:05:44.000 --> 0:05:48.320
<v Speaker 1>So walk us through the technical aspects of why you

0:05:48.400 --> 0:05:51.560
<v Speaker 1>think bitcoin doesn't work as a currency or as a

0:05:51.600 --> 0:05:57.719
<v Speaker 1>payment system. Okay, so let's start with the three things

0:05:57.720 --> 0:05:59.400
<v Speaker 1>you need to be able to do with the currency.

0:05:59.560 --> 0:06:01.960
<v Speaker 1>Need to be will acquire it, you need to be

0:06:02.000 --> 0:06:04.240
<v Speaker 1>able to hold onto it, and you need to be

0:06:04.279 --> 0:06:09.559
<v Speaker 1>able to spend it. Now, actually acquiring cryptocurrency is a

0:06:09.640 --> 0:06:15.160
<v Speaker 1>hard problem because cryptocurrency the one property it has that

0:06:15.240 --> 0:06:20.520
<v Speaker 1>the other payment systems don't is it's designed to be irreversible.

0:06:20.560 --> 0:06:24.360
<v Speaker 1>There's no go back or undo button, which means in

0:06:24.440 --> 0:06:27.480
<v Speaker 1>order to buy cryptocurrency, you have to do one of

0:06:27.600 --> 0:06:32.039
<v Speaker 1>three things. You either have to bring cash, so the

0:06:32.080 --> 0:06:34.520
<v Speaker 1>bitcoin a t m S don't take your ATAM card,

0:06:34.600 --> 0:06:39.320
<v Speaker 1>they take cash. Or you have to be given credit

0:06:39.720 --> 0:06:42.880
<v Speaker 1>by the seller of the cryptocurrency, so you transfer your

0:06:42.880 --> 0:06:47.200
<v Speaker 1>money electronically and are given credit. Or you have to wait,

0:06:47.400 --> 0:06:51.599
<v Speaker 1>so you transfer your money your to the exchange. The

0:06:51.640 --> 0:06:55.760
<v Speaker 1>exchange then sits on it for several days. Anyone who

0:06:55.880 --> 0:06:59.719
<v Speaker 1>doesn't follow these three rules when selling you cryptocurrency is

0:07:00.040 --> 0:07:04.320
<v Speaker 1>able to be defrauded because the rest of the financial

0:07:04.400 --> 0:07:09.200
<v Speaker 1>system is all designed with an undue button to mitigate fraud,

0:07:09.360 --> 0:07:12.680
<v Speaker 1>and so for example, one of the early bitcoin exchanges

0:07:12.960 --> 0:07:20.120
<v Speaker 1>used a PayPal clow that promise no chargebacks, and then

0:07:20.320 --> 0:07:23.880
<v Speaker 1>there were chargebacks and they went out of business. Likewise,

0:07:24.240 --> 0:07:28.320
<v Speaker 1>Steve Wozniaks sold seventy thousand dollars worth of bitcoin to

0:07:28.440 --> 0:07:31.760
<v Speaker 1>somebody who paid with PayPal, only to find out that

0:07:31.840 --> 0:07:35.360
<v Speaker 1>it was a fraudulent transaction. The PayPal was reversed and

0:07:35.440 --> 0:07:39.120
<v Speaker 1>he was out the bitcoin. Fortunately, I think the laws

0:07:39.240 --> 0:07:43.560
<v Speaker 1>can afford the loss. So they're hard to buy, they're

0:07:43.560 --> 0:07:48.680
<v Speaker 1>harder to hold onto. So if you store your cryptocurrency

0:07:48.920 --> 0:07:53.200
<v Speaker 1>on a third party exchange, you are on the hook

0:07:53.280 --> 0:07:57.560
<v Speaker 1>if they are hacked, and that has been billions of

0:07:57.680 --> 0:08:01.480
<v Speaker 1>dollars of notional value lost for the years as the

0:08:01.520 --> 0:08:05.840
<v Speaker 1>exchanges are hacked, and apparently North Korea is now one

0:08:05.880 --> 0:08:10.000
<v Speaker 1>of the big hackers on this. So you store your

0:08:10.000 --> 0:08:13.559
<v Speaker 1>cryptocurrency on your own computer, Well you can't do that either,

0:08:13.760 --> 0:08:18.080
<v Speaker 1>because if your computer is hacked, your cryptocurrency gets stolen.

0:08:18.160 --> 0:08:21.520
<v Speaker 1>And in fact, we used this one time to detect

0:08:21.640 --> 0:08:29.360
<v Speaker 1>a break in when the stole the monitored bitcoin from

0:08:29.440 --> 0:08:33.840
<v Speaker 1>a wallet that had a copy on a graduate student's account.

0:08:34.559 --> 0:08:38.720
<v Speaker 1>So you use a dedicated device, say like an iPhone

0:08:38.800 --> 0:08:43.040
<v Speaker 1>is a really strong device an iPhone, however, you're dependent

0:08:43.120 --> 0:08:47.319
<v Speaker 1>on the cryptocurrency software, and that cryptocurrency software may be

0:08:47.520 --> 0:08:51.800
<v Speaker 1>dependent on open source modules on GitHub that can be

0:08:51.960 --> 0:08:55.760
<v Speaker 1>bought by somebody else, taken over and include stealing code,

0:08:55.800 --> 0:09:00.000
<v Speaker 1>and this happened, so they're really hard to hold onto.

0:09:00.520 --> 0:09:07.040
<v Speaker 1>And finally you can't actually spend them because the dirty

0:09:07.040 --> 0:09:12.600
<v Speaker 1>little secret is the merchants who say they accept cryptocurrency, Well,

0:09:12.679 --> 0:09:17.079
<v Speaker 1>first of all, the volume hasn't increased in five years,

0:09:17.120 --> 0:09:22.880
<v Speaker 1>but they aren't actually accepting cryptocurrency because the cryptocurrency prices

0:09:22.920 --> 0:09:26.240
<v Speaker 1>bounced up and down. They use a service like bit pay,

0:09:26.400 --> 0:09:32.120
<v Speaker 1>which allows them to price in dollars and it immediately

0:09:32.160 --> 0:09:36.440
<v Speaker 1>converts the cryptocurrency into actual money. Even over Stock up

0:09:36.520 --> 0:09:41.240
<v Speaker 1>until a year ago, basically did not hold any cryptocurrency.

0:09:41.320 --> 0:09:45.679
<v Speaker 1>They just converted it all right away. Um well, they

0:09:45.920 --> 0:09:51.280
<v Speaker 1>held a teen amount um And so in order for

0:09:51.320 --> 0:09:56.440
<v Speaker 1>the system to balance, as somebody buying something with cryptocurrency,

0:09:56.520 --> 0:10:00.360
<v Speaker 1>because of that volatility risk the price bouncing up down,

0:10:00.720 --> 0:10:05.760
<v Speaker 1>you want to immediately transfer your dollars into cryptocurrency then

0:10:05.880 --> 0:10:10.560
<v Speaker 1>spend it, which means a real world cryptocurrency transaction costs

0:10:10.679 --> 0:10:14.720
<v Speaker 1>vastly more than the alternatives when you include those two

0:10:14.760 --> 0:10:19.280
<v Speaker 1>currency conversion steps, and one of which buying the cryptocurrency

0:10:19.480 --> 0:10:25.920
<v Speaker 1>is inherently expensive. So the only people who can avoid

0:10:26.000 --> 0:10:29.120
<v Speaker 1>that expensive buying cryptocurrency is the people who have been

0:10:29.520 --> 0:10:33.240
<v Speaker 1>holding onto it a long time because they're a believer. Now,

0:10:33.600 --> 0:10:37.040
<v Speaker 1>if you don't believe in cryptocurrency, there's no point. If

0:10:37.040 --> 0:10:41.280
<v Speaker 1>you do believe in cryptocurrencies, the one rule of them

0:10:41.400 --> 0:10:46.160
<v Speaker 1>is never actually spend them, because these are designed on

0:10:46.440 --> 0:10:50.120
<v Speaker 1>a gold standard type model. And as we remember our

0:10:50.160 --> 0:10:53.839
<v Speaker 1>economic history from the Great Depression, the only thing worse

0:10:53.840 --> 0:10:58.080
<v Speaker 1>than inflation is deflation that is the notion that your

0:10:58.080 --> 0:11:01.599
<v Speaker 1>currency is going to be worth more to borrow then today.

0:11:01.679 --> 0:11:07.079
<v Speaker 1>And these cryptocurrencies are supposed to be deflationary, which means

0:11:07.120 --> 0:11:12.400
<v Speaker 1>if you say, buy a pizza back in two thousand eleven, um,

0:11:12.520 --> 0:11:15.560
<v Speaker 1>you end up dining on regret when it looks like

0:11:15.600 --> 0:11:19.600
<v Speaker 1>a massive ten million a hundred million dollar pile of

0:11:19.640 --> 0:11:24.480
<v Speaker 1>money in So, if you don't believe in it, they

0:11:24.520 --> 0:11:27.080
<v Speaker 1>don't work for payments, and if you do believe it,

0:11:27.679 --> 0:11:32.360
<v Speaker 1>they don't work for payments. All right, So everything you

0:11:32.400 --> 0:11:35.480
<v Speaker 1>say makes a lot of sense in terms of Bitcoin

0:11:35.600 --> 0:11:40.000
<v Speaker 1>or any other cryptocurrencies not being not making any sense

0:11:40.040 --> 0:11:44.240
<v Speaker 1>whatsoever for what we would call conventional commerce. And um,

0:11:44.280 --> 0:11:48.680
<v Speaker 1>obviously the pro bitcoin rhetoric has changed a lot over time.

0:11:49.000 --> 0:11:52.400
<v Speaker 1>But something that strikes me listening to you and watching

0:11:52.440 --> 0:11:57.320
<v Speaker 1>your presentations and also talking to bitcoin believers is there

0:11:57.480 --> 0:12:00.640
<v Speaker 1>is a point of convergence. So they would say, yeah,

0:12:00.760 --> 0:12:05.719
<v Speaker 1>bitcoin isn't for buying, Bitcoin isn't for coffee, Bitcoin is

0:12:05.760 --> 0:12:08.520
<v Speaker 1>for uh, mostly for holding onto I would never spend

0:12:08.520 --> 0:12:11.440
<v Speaker 1>my bitcoin. The point of convergence, which you say in

0:12:11.440 --> 0:12:15.560
<v Speaker 1>your own presentation, the Tracy reference, is this idea of okay,

0:12:15.559 --> 0:12:18.560
<v Speaker 1>there is one thing that bitcoin is good for that

0:12:18.679 --> 0:12:22.560
<v Speaker 1>is censorship free transactions. So even with all the costs

0:12:22.600 --> 0:12:26.160
<v Speaker 1>that you describe the cost of acquiring, the risk of

0:12:26.760 --> 0:12:29.679
<v Speaker 1>losing your bitcoin, which is a calculable cost in theory,

0:12:29.720 --> 0:12:32.959
<v Speaker 1>and then the volatility cost that for a certain class

0:12:33.000 --> 0:12:37.640
<v Speaker 1>of transactions, um some of them outright crimes, some of

0:12:37.679 --> 0:12:41.080
<v Speaker 1>them gray areas, some of them more privacy related, that

0:12:41.280 --> 0:12:45.640
<v Speaker 1>cost might still be worth it. Yes, the one thing

0:12:45.760 --> 0:12:49.520
<v Speaker 1>that cryptocurrencies do that all the other payment systems don't

0:12:50.160 --> 0:12:55.120
<v Speaker 1>is by having no supposed central authority. We'll get to

0:12:55.200 --> 0:12:59.960
<v Speaker 1>why that's false. But they're designed to be censorship resisted.

0:13:00.160 --> 0:13:03.800
<v Speaker 1>There's nobody as a third party who is willing to

0:13:03.840 --> 0:13:09.760
<v Speaker 1>say no, you can't do forbidden activity. The problem is,

0:13:10.040 --> 0:13:13.680
<v Speaker 1>and this is why I've gotten much more sour over

0:13:13.720 --> 0:13:17.480
<v Speaker 1>the past five years, is I've come to the conclusion

0:13:17.720 --> 0:13:23.280
<v Speaker 1>that that is actually a bad thing. Bitcoin actually has

0:13:23.320 --> 0:13:26.200
<v Speaker 1>committed a crime against me. It has made me believe

0:13:26.440 --> 0:13:30.600
<v Speaker 1>in the need for rigorous enforcement of money laundering laws.

0:13:30.640 --> 0:13:34.400
<v Speaker 1>And I've got I'm a Silicon Valley quasi libertarian, and

0:13:34.440 --> 0:13:38.680
<v Speaker 1>I believe in the jack boot of justice on money laundry.

0:13:39.320 --> 0:13:43.440
<v Speaker 1>So what has happened with the cryptocurrencies, well, they get

0:13:43.559 --> 0:13:48.520
<v Speaker 1>used for drug deals yonn. But more importantly, they get

0:13:48.600 --> 0:13:53.120
<v Speaker 1>used for extortion. So give us cryptocurrency or your data

0:13:53.200 --> 0:13:56.240
<v Speaker 1>get Give us cryptocurrency, or we're going to keep sending

0:13:56.400 --> 0:14:00.720
<v Speaker 1>bomb threats. Um, how long before an airport is blackmailed

0:14:00.720 --> 0:14:03.760
<v Speaker 1>with give us cryptocurrency or you're going to get drones

0:14:03.880 --> 0:14:08.959
<v Speaker 1>flying over Um. It just ends up reaching out and

0:14:09.280 --> 0:14:13.000
<v Speaker 1>touching people in a very bad way. Then there's the theft,

0:14:13.280 --> 0:14:18.200
<v Speaker 1>that billions of dollars worth of theft, and then there's

0:14:18.240 --> 0:14:25.240
<v Speaker 1>the environment of what's left is pure speculation based on

0:14:26.000 --> 0:14:30.280
<v Speaker 1>somebody else being willing to pay more. But those markets

0:14:30.360 --> 0:14:37.280
<v Speaker 1>are so blatantly manipulated and fraudulent. So I consider every

0:14:37.400 --> 0:14:42.400
<v Speaker 1>I c O that was open to non accredited investors.

0:14:43.240 --> 0:14:48.560
<v Speaker 1>It is securities fraud. And that's just what we have

0:14:48.760 --> 0:14:54.320
<v Speaker 1>left is just basically um civil fraud, criminal fraud, and

0:14:54.960 --> 0:15:09.200
<v Speaker 1>rampant speculation and market manipulation. Yeah. So I want to

0:15:09.720 --> 0:15:13.280
<v Speaker 1>uh just pin down and uh not move on from

0:15:13.320 --> 0:15:16.000
<v Speaker 1>something that you said. You know, you say, Okay, the

0:15:16.080 --> 0:15:19.040
<v Speaker 1>only thing that it's really good for things like drug deals,

0:15:19.280 --> 0:15:22.480
<v Speaker 1>and it's given rise to a new model of extortion.

0:15:23.480 --> 0:15:27.720
<v Speaker 1>It only works because in theory the censorship resistance and

0:15:27.760 --> 0:15:30.920
<v Speaker 1>the decentralization so that no one can say this transaction

0:15:31.240 --> 0:15:33.880
<v Speaker 1>isn't allowed. But you threw in there and said we're

0:15:33.880 --> 0:15:36.320
<v Speaker 1>going to get back to it. But even that is

0:15:36.320 --> 0:15:38.520
<v Speaker 1>a false promise. And I really think this is the

0:15:38.600 --> 0:15:43.720
<v Speaker 1>sort of central question of do you think the censorship

0:15:43.760 --> 0:15:48.400
<v Speaker 1>resistant slash decentralization case for bitcoin? Why is that also

0:15:48.960 --> 0:15:53.880
<v Speaker 1>not actually live up to the hype. So it lives

0:15:53.960 --> 0:15:58.000
<v Speaker 1>up to the hype on censorship resistance, it does provide that,

0:15:58.520 --> 0:16:03.360
<v Speaker 1>but the notion of the centralization, So decentralization the idea is,

0:16:04.120 --> 0:16:06.920
<v Speaker 1>let's make it so that you don't have to trust

0:16:07.040 --> 0:16:11.160
<v Speaker 1>any individual or small group of entities, but only the

0:16:11.200 --> 0:16:16.520
<v Speaker 1>system as a whole. Now, the benefits of decentralization, apart

0:16:16.760 --> 0:16:22.320
<v Speaker 1>from censorship resistance, are never clearly articulated. It's basically an

0:16:22.440 --> 0:16:28.680
<v Speaker 1>article of beliefs. But assuming that that is good for something,

0:16:29.280 --> 0:16:34.280
<v Speaker 1>the results has been dismal. They cost a huge amount

0:16:34.320 --> 0:16:38.240
<v Speaker 1>to run, but they don't end up being decentralized. So

0:16:38.680 --> 0:16:43.800
<v Speaker 1>cryptocurrency mining for bitcoin is controlled by basically four entities.

0:16:44.160 --> 0:16:50.320
<v Speaker 1>Four entities can conspire together and completely control what transactions

0:16:50.360 --> 0:16:56.840
<v Speaker 1>get approved or not likewise, so there's no actual decentralization,

0:16:56.920 --> 0:17:02.240
<v Speaker 1>there's just a veneer of decentralization. Likewise, the code developers

0:17:02.320 --> 0:17:08.160
<v Speaker 1>themselves are central authorities as well. So take Etherium for example.

0:17:08.160 --> 0:17:12.480
<v Speaker 1>Ethereum is all code is law and no central authorities.

0:17:12.920 --> 0:17:17.320
<v Speaker 1>But when seven percent of all Ethereum got invested in

0:17:17.680 --> 0:17:22.320
<v Speaker 1>basically a self creating ponzi scheme that had a bug

0:17:22.359 --> 0:17:25.199
<v Speaker 1>in it that allowed the money to get stolen, the

0:17:25.280 --> 0:17:29.840
<v Speaker 1>developers went, oh, you know that whole code is law business. Um, Yeah,

0:17:29.880 --> 0:17:33.679
<v Speaker 1>that's a lie. We're changing the code, undo the theft

0:17:33.800 --> 0:17:37.679
<v Speaker 1>because it was our money you stole. Yeah. I've wondered

0:17:37.680 --> 0:17:40.800
<v Speaker 1>about this at various times, especially with the forks that

0:17:40.840 --> 0:17:44.679
<v Speaker 1>we've seen in well, notably in in bitcoin, where we

0:17:44.800 --> 0:17:48.560
<v Speaker 1>do seem to have the overall direction of bitcoin being

0:17:48.640 --> 0:17:53.640
<v Speaker 1>determined by consensus and by users. So like, how how

0:17:53.720 --> 0:17:59.680
<v Speaker 1>much of a problem are those forks? Well, they are

0:18:00.040 --> 0:18:05.359
<v Speaker 1>and they aren't. They are if you actually believe that

0:18:05.440 --> 0:18:09.280
<v Speaker 1>decentralization is supposed to mean something, because these forks are

0:18:09.400 --> 0:18:15.600
<v Speaker 1>not some large community thing but just a few individuals,

0:18:15.680 --> 0:18:21.840
<v Speaker 1>the the cartels on the mining and or the coders. Um.

0:18:22.240 --> 0:18:27.000
<v Speaker 1>So if you actually believe that decentralization is important somehow

0:18:27.400 --> 0:18:30.640
<v Speaker 1>these forks are problematic. Otherwise for the rest of us,

0:18:30.760 --> 0:18:36.840
<v Speaker 1>it's just basically popcorn. It's entertaining to watch the interesting

0:18:37.080 --> 0:18:42.439
<v Speaker 1>conflicts between various camps and the big block versus small block.

0:18:42.560 --> 0:18:47.800
<v Speaker 1>It's like big Indian versus little endian Um. And so

0:18:48.000 --> 0:18:55.600
<v Speaker 1>it's entertainment, but it's not anything really fundamental from a

0:18:55.840 --> 0:19:01.760
<v Speaker 1>systemic viewpoint, because they're all just only worth something because

0:19:01.800 --> 0:19:05.760
<v Speaker 1>somebody else will pay for it. So well, it's a

0:19:05.800 --> 0:19:09.080
<v Speaker 1>good example that the notion of limited supply is. It's

0:19:09.119 --> 0:19:11.960
<v Speaker 1>true because you can just create more of these out

0:19:11.960 --> 0:19:17.120
<v Speaker 1>of the air, but other than that, it's just amusement value. So, Nick,

0:19:17.160 --> 0:19:18.840
<v Speaker 1>I wanted to go back to something you were saying

0:19:18.880 --> 0:19:22.560
<v Speaker 1>earlier about the regulatory response, and this is something that

0:19:22.640 --> 0:19:27.080
<v Speaker 1>I've I've wondered at various times myself, probably on Twitter

0:19:27.200 --> 0:19:32.800
<v Speaker 1>at some point, But if regulators are sort of missing

0:19:32.880 --> 0:19:34.679
<v Speaker 1>a trick because they're going to get a bunch of

0:19:34.680 --> 0:19:38.919
<v Speaker 1>burned investors, either via crypto investments or I c O s,

0:19:39.680 --> 0:19:43.040
<v Speaker 1>why aren't they acting and why? The other thing that

0:19:43.040 --> 0:19:45.400
<v Speaker 1>I often wonder is if if you think that crypto

0:19:45.640 --> 0:19:49.160
<v Speaker 1>is going to be a legitimate currency sometime in the future,

0:19:49.600 --> 0:19:52.840
<v Speaker 1>then surely that would undermine you know, various regulators and

0:19:52.880 --> 0:19:56.480
<v Speaker 1>monetary authorities as well, so they should be acting. So like,

0:19:56.680 --> 0:19:59.520
<v Speaker 1>either way, either it's a fraud or either it's going

0:19:59.560 --> 0:20:02.440
<v Speaker 1>to be six tessful, you would think there should be

0:20:02.520 --> 0:20:07.200
<v Speaker 1>some sort of regulatory response. I would have hoped so,

0:20:07.720 --> 0:20:12.080
<v Speaker 1>But I think what it comes down to is regulators

0:20:12.119 --> 0:20:17.280
<v Speaker 1>these days are afraid of being claimed to stifle innovation.

0:20:18.320 --> 0:20:23.440
<v Speaker 1>And the cryptocurrency believers have talked a very good story

0:20:23.680 --> 0:20:28.280
<v Speaker 1>about how they're being innovative and new um even if

0:20:28.359 --> 0:20:32.359
<v Speaker 1>in reality they're basically speed running five years of economic

0:20:32.440 --> 0:20:36.119
<v Speaker 1>failures over and over and over again. But so the

0:20:36.200 --> 0:20:39.760
<v Speaker 1>result is the regulators have in the past been very

0:20:39.880 --> 0:20:43.560
<v Speaker 1>hands off, so like you had all these I c

0:20:43.720 --> 0:20:48.240
<v Speaker 1>O s and it just you just look at it

0:20:48.400 --> 0:20:51.879
<v Speaker 1>and it fails. The how he tests that, the test

0:20:52.000 --> 0:20:56.440
<v Speaker 1>for is this a security? And what I think has

0:20:56.480 --> 0:21:01.000
<v Speaker 1>happened is now that things are collapsing, the regulators are

0:21:01.040 --> 0:21:07.560
<v Speaker 1>finally starting to pay attention, and so the regulators are reactive.

0:21:07.680 --> 0:21:11.080
<v Speaker 1>They are not proactive, and so as a consequence that

0:21:11.560 --> 0:21:17.520
<v Speaker 1>they sat back during the boom did nothing, and now

0:21:17.560 --> 0:21:21.119
<v Speaker 1>that it's a bus they're going to go and probably

0:21:22.800 --> 0:21:26.240
<v Speaker 1>drop a lot of lawsuits and probably invite some people

0:21:26.400 --> 0:21:29.639
<v Speaker 1>because now that the tide is rushing out, you're seeing

0:21:29.680 --> 0:21:35.960
<v Speaker 1>that everyone is naked. Um, they're actually doing something, and

0:21:36.240 --> 0:21:41.080
<v Speaker 1>I think it really is. Regulators are afraid of regulating

0:21:43.080 --> 0:21:47.760
<v Speaker 1>new or old wine in new bottles. They think it's new,

0:21:48.440 --> 0:21:51.760
<v Speaker 1>they don't know what to do yet, and so as

0:21:51.760 --> 0:21:59.040
<v Speaker 1>a consequence, they just basically did nothing during the and well,

0:21:59.160 --> 0:22:01.479
<v Speaker 1>now they get the joys of picking up the pieces.

0:22:02.320 --> 0:22:04.760
<v Speaker 1>I wanna go back to where you say this whole

0:22:04.800 --> 0:22:11.560
<v Speaker 1>cryptocurrency uh phase has sort of damaged your natural libertarian

0:22:11.640 --> 0:22:15.240
<v Speaker 1>instincts because now you have this appreciation for this money

0:22:15.320 --> 0:22:19.439
<v Speaker 1>laundering regulation. I'm like struck on this point that in

0:22:19.440 --> 0:22:23.040
<v Speaker 1>this sense, your your view on cryptocurrencies is not all

0:22:23.119 --> 0:22:25.639
<v Speaker 1>that different from a lot of believers, which is that

0:22:25.960 --> 0:22:29.320
<v Speaker 1>it really comes down to censorship resistance. You point out

0:22:29.440 --> 0:22:32.080
<v Speaker 1>that that's mostly used for drug dealers and all kinds

0:22:32.080 --> 0:22:34.399
<v Speaker 1>of things that are awful. They would say, yes, that

0:22:34.560 --> 0:22:36.919
<v Speaker 1>is a byproduct of what happens when you have freedom,

0:22:36.960 --> 0:22:38.679
<v Speaker 1>and that you know there are good things that can

0:22:38.720 --> 0:22:41.919
<v Speaker 1>come out of censorship resistance, that there are people in

0:22:42.119 --> 0:22:44.920
<v Speaker 1>areas of the world, or people in lines of work

0:22:45.040 --> 0:22:47.119
<v Speaker 1>for whatever reason they don't want their bank to know,

0:22:47.520 --> 0:22:49.520
<v Speaker 1>or maybe their bank cracks down on their line of

0:22:49.560 --> 0:22:52.160
<v Speaker 1>work if their say a sex work or something like that.

0:22:52.600 --> 0:22:55.880
<v Speaker 1>And they would say that, yes, there's money laundering and crime,

0:22:55.920 --> 0:22:57.800
<v Speaker 1>but that is the price that you pay for also

0:22:57.840 --> 0:23:02.240
<v Speaker 1>having this freedom. And they would also say say that, um,

0:23:02.280 --> 0:23:05.920
<v Speaker 1>this debate has happened before in cryptography and the sort

0:23:05.920 --> 0:23:09.520
<v Speaker 1>of export of you know, a strong cryptography where people say, oh,

0:23:09.560 --> 0:23:13.320
<v Speaker 1>if cryptography exists, and that's going to be good only

0:23:13.359 --> 0:23:15.920
<v Speaker 1>for terrorists, but that also is what enabled the web

0:23:15.960 --> 0:23:18.159
<v Speaker 1>to work. So how much is this really like a

0:23:18.240 --> 0:23:24.000
<v Speaker 1>technical fight versus essentially a values fight? I think at

0:23:24.119 --> 0:23:30.119
<v Speaker 1>this point it is a values fight. And I really

0:23:30.200 --> 0:23:36.040
<v Speaker 1>don't like that cryptography analogy because cryptography we've always seen

0:23:36.960 --> 0:23:40.360
<v Speaker 1>good uses for it right from the start. But with

0:23:40.480 --> 0:23:46.159
<v Speaker 1>the cryptocurrencies, the problem is is people can't point to

0:23:47.600 --> 0:23:54.719
<v Speaker 1>legit payment system. So what has censorship resistance allowed you

0:23:54.800 --> 0:24:00.320
<v Speaker 1>to do that? Um, that the others happen. Well, okay,

0:24:00.760 --> 0:24:04.320
<v Speaker 1>if you need censorship resistance, you always still have cash.

0:24:04.840 --> 0:24:09.000
<v Speaker 1>It's just that cash has both the need for physical

0:24:09.080 --> 0:24:17.520
<v Speaker 1>proximity and significant mass. So scaling cash. Moving a thousand

0:24:17.600 --> 0:24:20.920
<v Speaker 1>bucks is easy, moving a million bucks is hard. So

0:24:21.040 --> 0:24:28.480
<v Speaker 1>cryptocurrencies want to um enable that moving large quantities. And

0:24:28.560 --> 0:24:32.520
<v Speaker 1>the other thing is is I've just seen the damage

0:24:32.560 --> 0:24:37.639
<v Speaker 1>that is done. So people point to cryptocurrency being used

0:24:37.640 --> 0:24:43.000
<v Speaker 1>in two good situations to get around censorship. The first

0:24:43.200 --> 0:24:46.120
<v Speaker 1>was payments to Wiki leaks. So Wiki leaks was cut

0:24:46.119 --> 0:24:49.840
<v Speaker 1>off from the banking system back around when Assange first

0:24:49.840 --> 0:24:53.400
<v Speaker 1>fled to the embassy to avoid the sex assault charges.

0:24:54.280 --> 0:24:58.600
<v Speaker 1>So when that happened, um, you could use cryptocurrency if

0:24:58.640 --> 0:25:01.879
<v Speaker 1>you wanted to support Wiki weeks, and that's all fine

0:25:01.880 --> 0:25:05.760
<v Speaker 1>and good, but Wiki Leaks decided that it's actually better

0:25:05.920 --> 0:25:10.760
<v Speaker 1>just to arrange with a US nonprofit to act as

0:25:10.800 --> 0:25:17.320
<v Speaker 1>an intermediary and basically launder contributions. And then we had Backpage.

0:25:17.440 --> 0:25:22.000
<v Speaker 1>So Backpage was a Craigslist clone that did a lot

0:25:22.040 --> 0:25:26.640
<v Speaker 1>of support for sex workers, and I actually think, yeah,

0:25:26.800 --> 0:25:31.520
<v Speaker 1>that probably was good overall, or at least been less

0:25:31.560 --> 0:25:34.480
<v Speaker 1>damaging than the alternatives. But they were cut off from

0:25:34.520 --> 0:25:37.880
<v Speaker 1>the banking system, and so to pay with them, you'd

0:25:37.920 --> 0:25:41.720
<v Speaker 1>either have to pay with cryptocurrency or you send them

0:25:42.240 --> 0:25:45.720
<v Speaker 1>a check in the mail. UM, and I suspect most

0:25:45.760 --> 0:25:50.600
<v Speaker 1>of their payments became checks in the mail. Now the

0:25:50.680 --> 0:25:54.040
<v Speaker 1>problem is is, let's face it, Backpage turned out to

0:25:54.119 --> 0:25:59.600
<v Speaker 1>be a criminal conspiracy, and so we're left with very

0:26:00.040 --> 0:26:06.800
<v Speaker 1>you non criminal usages because it is so expensive. So

0:26:07.960 --> 0:26:12.520
<v Speaker 1>it's actually a lot more expensive than the other anonymous

0:26:12.520 --> 0:26:15.320
<v Speaker 1>electronic payments you want. So if you want to buy

0:26:15.359 --> 0:26:19.879
<v Speaker 1>your porn anonymously, you go into Target, pay a hundred

0:26:19.880 --> 0:26:23.120
<v Speaker 1>and four dollars for a Visa gift card, and now

0:26:23.200 --> 0:26:25.879
<v Speaker 1>you can use that Visa gift card to buy your porn.

0:26:26.040 --> 0:26:30.960
<v Speaker 1>So the cost of privacy on electronic transactions is actually

0:26:31.359 --> 0:26:36.280
<v Speaker 1>a lot less than the cryptocurrencies offer because you you

0:26:36.400 --> 0:26:39.199
<v Speaker 1>have this huge problem of you can't hold onto the

0:26:39.200 --> 0:26:43.000
<v Speaker 1>cryptocurrencies you can hold onto a Visa gift card. Never

0:26:43.080 --> 0:26:46.280
<v Speaker 1>say odd lots doesn't bring us a useful day to

0:26:46.359 --> 0:26:50.160
<v Speaker 1>day information and life tips um nick. On a serious note,

0:26:50.480 --> 0:26:55.679
<v Speaker 1>if this is all about differences and values or value systems,

0:26:55.800 --> 0:27:02.159
<v Speaker 1>and given that cryptocurrency supporters seemed to be so invested

0:27:02.280 --> 0:27:06.679
<v Speaker 1>in the belief system around crypto and everything that comes

0:27:06.760 --> 0:27:10.840
<v Speaker 1>with it, what ultimately is going to be the thing

0:27:11.520 --> 0:27:15.280
<v Speaker 1>that destroys cryptocurrencies. As you put it in your presentation,

0:27:15.320 --> 0:27:18.600
<v Speaker 1>that ends up burning them with fire in some way.

0:27:19.240 --> 0:27:22.919
<v Speaker 1>There's two things that can really burn the system with fire.

0:27:23.760 --> 0:27:29.000
<v Speaker 1>The first is the federal government UM getting their act

0:27:29.040 --> 0:27:35.040
<v Speaker 1>together and going after this cryptocurrency called tether. So tether

0:27:35.359 --> 0:27:39.520
<v Speaker 1>is effectively a digital banknote. It's supposedly tied one to

0:27:39.640 --> 0:27:44.640
<v Speaker 1>one with the dollar, but it's not. It's a basically

0:27:44.920 --> 0:27:50.760
<v Speaker 1>it's reinventing eighteenth century banking combined with Liberty Reserve, which

0:27:50.800 --> 0:27:54.160
<v Speaker 1>was a criminal enterprise the Feds shut down a few

0:27:54.240 --> 0:27:59.399
<v Speaker 1>years back, and so it's a rife target for disruption.

0:28:00.320 --> 0:28:06.920
<v Speaker 1>But if the uh tether is removed, that actually destroys

0:28:06.960 --> 0:28:13.240
<v Speaker 1>almost the entire bitcoin exchange ecology. So eight of the

0:28:13.240 --> 0:28:17.440
<v Speaker 1>cryptocurrency volume on the exchanges are on exchanges that are

0:28:17.520 --> 0:28:21.200
<v Speaker 1>already cut off from the banking system because they're viewed

0:28:21.200 --> 0:28:25.400
<v Speaker 1>by the banks. Is basically too high risk fraudulent enterprises

0:28:25.560 --> 0:28:28.960
<v Speaker 1>with a huge amount of wash trading and painting the

0:28:29.080 --> 0:28:34.280
<v Speaker 1>tape and such blatant market manipulation that the price graphs

0:28:34.320 --> 0:28:39.400
<v Speaker 1>look like Bart Simpson's haircuts. UM. So if you remove

0:28:39.520 --> 0:28:46.120
<v Speaker 1>tether basically removed the entire exchange ecology except for a

0:28:46.240 --> 0:28:50.920
<v Speaker 1>few and so that alone would have a huge negative impact,

0:28:51.040 --> 0:28:56.480
<v Speaker 1>and tether is such latently a crime under money laundering

0:28:56.600 --> 0:29:00.600
<v Speaker 1>laws that it's surprising they haven't been prosecuted yet. So

0:29:00.720 --> 0:29:05.480
<v Speaker 1>that's one. Number two is all these proof of work coins.

0:29:05.520 --> 0:29:08.600
<v Speaker 1>So the idea behind proof of work, which is what

0:29:08.720 --> 0:29:12.920
<v Speaker 1>predicts Bitcoin, ethereum and most of the other major cryptocurrencies,

0:29:13.480 --> 0:29:19.200
<v Speaker 1>is basically better described as burning money. So the system

0:29:19.240 --> 0:29:24.480
<v Speaker 1>burns x thousands of dollars an hour under the assumption

0:29:24.640 --> 0:29:27.800
<v Speaker 1>that an attacker to attack the system would have to

0:29:27.840 --> 0:29:31.760
<v Speaker 1>burn more than that. The problem is, in order to

0:29:31.880 --> 0:29:35.440
<v Speaker 1>defend the system, you have to be burning x dollars

0:29:35.440 --> 0:29:39.400
<v Speaker 1>an hour continuously, but an attacker might only have to

0:29:39.480 --> 0:29:43.440
<v Speaker 1>burn x dollars for a limited period of time, an

0:29:43.480 --> 0:29:47.480
<v Speaker 1>hour or two. And so what has happened is the

0:29:47.520 --> 0:29:52.200
<v Speaker 1>cryptocurrency systems that only cost five thousand dollars an hour

0:29:52.360 --> 0:29:56.840
<v Speaker 1>to run, the so called alt coins um, there's less

0:29:56.880 --> 0:30:00.800
<v Speaker 1>polite turns to them as well. Those have actually become

0:30:00.960 --> 0:30:06.720
<v Speaker 1>regularly attacked by people who burn six thousand dollars for

0:30:06.800 --> 0:30:12.080
<v Speaker 1>an hour and use it to conduct fraudulent transactions targeting

0:30:12.560 --> 0:30:19.080
<v Speaker 1>cryptocurrency exchanges. So if you're inefficient, or if you're efficient,

0:30:19.320 --> 0:30:25.680
<v Speaker 1>you're vulnerable but if you're burning bitcoin level of money, uh,

0:30:25.960 --> 0:30:29.720
<v Speaker 1>thousands of dollars or so, like bitcoin is what about

0:30:29.880 --> 0:30:34.080
<v Speaker 1>five million dollars a day right now? Um, if you're

0:30:34.080 --> 0:30:37.960
<v Speaker 1>burning five million dollars a day, yes, you are secure

0:30:38.000 --> 0:30:41.920
<v Speaker 1>against an attacker, but you are so dependent on the

0:30:42.000 --> 0:30:45.320
<v Speaker 1>price that you need five million dollars a day of

0:30:45.640 --> 0:30:49.200
<v Speaker 1>new money coming in just to keep the lights on.

0:30:50.080 --> 0:30:56.640
<v Speaker 1>So if the cryptocurrency drops in price, it actually creates

0:30:56.760 --> 0:30:59.640
<v Speaker 1>a death spiral situation where you've got a lot of

0:30:59.680 --> 0:31:03.160
<v Speaker 1>mind new equipment that we'll get turned off because it's

0:31:03.200 --> 0:31:07.520
<v Speaker 1>not profitable to protect the network, but it may be

0:31:07.600 --> 0:31:11.160
<v Speaker 1>profitable to turn on for an hour or two to

0:31:11.320 --> 0:31:16.400
<v Speaker 1>attack the network. And so as long as the price

0:31:16.600 --> 0:31:23.160
<v Speaker 1>stays high and growing, the system is secure. But in

0:31:23.280 --> 0:31:27.160
<v Speaker 1>order for that to happen, they keep needing five million

0:31:27.200 --> 0:31:31.959
<v Speaker 1>dollars a day plus of new suckers coming in wanting

0:31:31.960 --> 0:31:36.680
<v Speaker 1>to buy the cryptocurrency, and that's net inflow of new money.

0:31:37.040 --> 0:31:41.280
<v Speaker 1>And if that ever stops, the price starts to drop,

0:31:41.720 --> 0:31:45.080
<v Speaker 1>and then we get into these death spiral situations where

0:31:45.480 --> 0:31:49.360
<v Speaker 1>they lose all their security. All right, Well, Nick Weaver,

0:31:49.800 --> 0:31:51.600
<v Speaker 1>it was great having you on. Thanks so much for

0:31:51.680 --> 0:31:55.640
<v Speaker 1>walking us through all the the tech arguments underlying the

0:31:55.720 --> 0:31:59.600
<v Speaker 1>antique crypto case. Thank you, thank you very much for

0:31:59.600 --> 0:32:18.160
<v Speaker 1>having Joe. I thought that conversation was absolutely fantastic, really

0:32:18.200 --> 0:32:22.520
<v Speaker 1>great to get an actual, you know, computer scientist view

0:32:22.800 --> 0:32:27.640
<v Speaker 1>of cryptocurrencies and how blockchain technology is working, but also

0:32:27.880 --> 0:32:30.720
<v Speaker 1>to have someone sort of put it in that comical

0:32:30.800 --> 0:32:34.400
<v Speaker 1>language is just fantastic. Yeah, I agree, and I do

0:32:34.480 --> 0:32:36.920
<v Speaker 1>think it was interesting to me though that like at

0:32:36.960 --> 0:32:41.080
<v Speaker 1>its core, there isn't this area of overlap that in

0:32:41.120 --> 0:32:45.880
<v Speaker 1>a sense, the blockchain or the bitcoin blockchain kind of

0:32:45.920 --> 0:32:49.040
<v Speaker 1>does what it's supposed to do, like it works. It's

0:32:49.120 --> 0:32:51.800
<v Speaker 1>just that it works in a very narrow case, and

0:32:51.840 --> 0:32:54.120
<v Speaker 1>you have to make the case that that narrow u

0:32:54.360 --> 0:32:57.000
<v Speaker 1>that narrow use case actually has some benefit and is

0:32:57.000 --> 0:33:00.160
<v Speaker 1>worth all the cost, which you don't really hear. You're

0:33:00.640 --> 0:33:04.360
<v Speaker 1>even most of these sort of like crypto bitcoin blockchain

0:33:04.680 --> 0:33:09.240
<v Speaker 1>enthusiasts articulating what that point is. So I find it

0:33:09.400 --> 0:33:12.280
<v Speaker 1>very helpful that I feel like we're sort of getting

0:33:12.280 --> 0:33:14.920
<v Speaker 1>to the nub of the issue, which is that is

0:33:15.000 --> 0:33:18.880
<v Speaker 1>this sort of narrow use case actually a benefit, uh

0:33:19.080 --> 0:33:23.960
<v Speaker 1>that societal benefit or not or a project worth pursuing. Well,

0:33:24.000 --> 0:33:25.360
<v Speaker 1>I think that's a good way to frame it. And

0:33:25.360 --> 0:33:28.560
<v Speaker 1>I think there's probably an obvious reason why crypto proponents

0:33:28.680 --> 0:33:31.760
<v Speaker 1>don't talk about the narrow base case, which is essentially

0:33:32.120 --> 0:33:35.280
<v Speaker 1>criminality and money laundring and blackmail. And I say that

0:33:35.360 --> 0:33:39.760
<v Speaker 1>as someone who recently got a blackmail email on the

0:33:39.800 --> 0:33:44.600
<v Speaker 1>Bloomberg system requesting ten thousand dollars worth of bitcoin, which

0:33:44.640 --> 0:33:47.400
<v Speaker 1>they helpfully translated. I think it was to two point

0:33:47.480 --> 0:33:52.320
<v Speaker 1>five or two point six bitcoin immediately deposited into their wallet. Um,

0:33:52.480 --> 0:33:56.880
<v Speaker 1>so that does definitely happen. No, I didn't. Apparently there's

0:33:56.920 --> 0:34:00.920
<v Speaker 1>a pending CIA investigation against me, so if I disappeared tomorrow,

0:34:01.000 --> 0:34:04.520
<v Speaker 1>you know why. But I will say I actually I

0:34:04.640 --> 0:34:09.680
<v Speaker 1>disagree on the point that it does have an especially

0:34:09.920 --> 0:34:14.080
<v Speaker 1>good use for criminal activities. I still think at its

0:34:14.080 --> 0:34:19.000
<v Speaker 1>heart the technology is unwieldy and inefficient for reasons of

0:34:19.040 --> 0:34:22.920
<v Speaker 1>either energy consumption or the notion that the blockchain can

0:34:22.960 --> 0:34:26.480
<v Speaker 1>be edited. It's not immutable, and you're trying to create

0:34:26.520 --> 0:34:29.719
<v Speaker 1>trust amongst entities that don't trust each other anyway, and

0:34:29.760 --> 0:34:31.680
<v Speaker 1>if they did trust each other, they would come up

0:34:31.719 --> 0:34:34.880
<v Speaker 1>with some other sort of contract system. Well, the point

0:34:34.960 --> 0:34:38.719
<v Speaker 1>that Nicholas made at the end that there is. You know,

0:34:38.719 --> 0:34:42.000
<v Speaker 1>there are frailties. I mean, people would there's debate about this,

0:34:42.040 --> 0:34:45.359
<v Speaker 1>but this death spiral, like, ultimately, if there are a

0:34:45.400 --> 0:34:49.960
<v Speaker 1>lot of the value currently in cryptocurrencies is premised on

0:34:50.000 --> 0:34:53.520
<v Speaker 1>the idea that they have. Oh there's all kinds of

0:34:53.760 --> 0:34:57.480
<v Speaker 1>machine internet of things and machine machine transactions, all this stuff.

0:34:57.680 --> 0:34:59.640
<v Speaker 1>If a lot of the value are still people believing

0:34:59.680 --> 0:35:02.560
<v Speaker 1>in that at then it's easy to imagine a big

0:35:02.640 --> 0:35:05.120
<v Speaker 1>drop in value from here that the death spiral, and

0:35:05.160 --> 0:35:07.080
<v Speaker 1>then the whole thing breaks up. And if the trades

0:35:07.120 --> 0:35:09.880
<v Speaker 1>actions were to ever get unwound or edited in some

0:35:09.960 --> 0:35:13.000
<v Speaker 1>way in an attack, then that really would strike to

0:35:13.040 --> 0:35:16.080
<v Speaker 1>the heart of the entire Oh, this is immutable, and

0:35:16.160 --> 0:35:19.360
<v Speaker 1>this is censorship resistant, So it feels like even on

0:35:19.440 --> 0:35:22.160
<v Speaker 1>the core use, the jury is still out about whether

0:35:22.200 --> 0:35:24.440
<v Speaker 1>that will work. Yeah, and on the plus side, I

0:35:24.480 --> 0:35:27.719
<v Speaker 1>guess as the price of bitcoin dips lower, we will

0:35:27.840 --> 0:35:30.480
<v Speaker 1>get to see whether or not the death spiral will

0:35:30.480 --> 0:35:34.840
<v Speaker 1>actually happen. So that's something to look forward to. This

0:35:34.920 --> 0:35:37.919
