Bitcoin Hard Fork Predictions

Tomorrow there is scheduled to be a hard fork of the Bitcoin blockchain and network. There’s a fair amount of uncertainty over what will happen. The hashrate is unknowable until the fork occurs. The price seems to be around 10% of the price of Bitcoin. However, there aren’t too many exchanges that will be accepting this currency, and there are even fewer places you can actually spend it.

I’m going to make some predictions about it to put on record what I think is going to occur and to see how correct or incorrect I end up being.

  1. There will be a Bitcoin Cash block mined before 12 AM August 2, US Eastern time: 80%
  2. The price of Bitcoin Cash at 12 AM August 2, US Eastern time will be <10% of Bitcoin’s price: 70%
  3. The price of Bitcoin Cash on August 5 will be < 10% of Bitcoin’s price: 90%
  4. The price of Bitcoin Cash on September 1 will be < 10% of Bitcoin’s price: 90%
  5. The value of all transactions of Bitcoin Cash around September 1 (maybe averaged over a week?) will be < 10% of the value of all transactions in Bitcoin: 95%

I have mixed hopes for the success of Bitcoin Cash. On the one hand, I wrote previously that if the two factions in Bitcoin split, we could have a competitive market showing which rules were better. However, due to network effects, I still don’t think it could happen and be very successful. Supposing it did succeed though (had a pretty high market price), what would that mean? I suppose it would mean forks would become more common. That might be better for competition, but not for stability of the currency.

Ultimately, the idea that it would be fairly easy to make a successful hard fork of Bitcoin would be pretty devastating to Bitcoin’s health. It would mean consensus doesn’t mean much, it would mean the Bitcoin community could splinter pretty easily, which would therefore mean Bitcoin’s usefulness as a currency decreases as each part of the community would be using their own forked blockchain and coin. Something like sidechains seems like a much better implementation of this idea.

I should probably also disclose that I do not have much faith in the current governance model of Bitcoin Cash, and that does concern me a bit as well. I hope that hasn’t clouded my judgment of the actual technological and economic implications, but only time will tell if my predictions are true.

A Few Thoughts on Bitcoin

I have been aware of Bitcoin’s existence for a while, and while I was excited about it a few years ago, it had somewhat dropped off my radar. Perhaps because over the past few months, Bitcoin has seen a big increase in value, I started to revisit it and analyze it as a technology. My experience has been nothing short of breathtaking.

A few years ago, Bitcoin was pretty cool. I even wrote a paper about it, discussing the huge potential of the technology and decentralized, autonomous transactions could totally upend the banking industry. But back when I first got into Bitcoin, I was also interested in Austrian Economics, which I’m largely over now. Their focus on control of the money supply and dire warnings about the Federal Reserve weren’t really borne out by the rather mundane economic growth of the last few years.

Nonetheless, the Bitcoin community has been working on without me, and it has paid off: you can now use Bitcoin to purchase from all sorts of retailers, including Dell, Overstock.com, Newegg, and more. You can also buy all sorts of internet specific services, which to me seems like the clearest use case. These include Steam credit, VPNs, cloud hosting, and even Reddit gold.

The price has jumped up to over $1000 at the end of April 2017 (that’s over $18 billion in total market value of all Bitcoins), and it was briefly even higher a month ago on speculation the SEC would allow for a Bitcoin ETF. The ETF was rejected, but the potential of the currency remains. And technologically, Bitcoin is far more impressive than it was, most notably with a concept called the Lightning Network.

This technology would allow for instantaneous Bitcoin transactions (without having to accept risky zero confirmation transactions). These transactions would have the full security of the Bitcoin network, and would also likely allow massive scaling of the Bitcoin payment network. Drivechain is another project with great potential to scale Bitcoin and allow for applications to be built on top of the Bitcoin blockchain. It would create a two-way peg, enforced by miners, that allowed tokens to be converted from Bitcoin to other sidechains and back again. This would allow experimentation of tons of new applications without risk to the original Bitcoin blockchain.

Hivemind is particularly exciting as a decentralized prediction market that is not subject to a central group creating markets; anyone can create and market and rely on a consensus algorithm to declare outcomes. If attached to the Bitcoin blockchain, it also wouldn’t suffer from cannibalization that Ethereum blockchains like Augur can suffer from.

Mimblewimble is another interesting sidechain idea. It combines concepts of confidential transactions with (I think) homomorphic encryption to allow for completely unknowable transaction amounts and untraceable transaction histories. It would also do this while keeping the required data to run the blockchain fairly low (the Bitcoin blockchain grows over time). It would have to be implemented as a sidechain, but any transactions that occur there would be completely untraceable.

And there are even more cool projects: Namecoin, JoinMarket, the Elements Project, and of course other cryptocurrencies like Ethereum, Monero, and Zcash. This really makes the future of Bitcoin and cryptocurrencies seem pretty bright.

However, we’ve skipped a big point, which is that most of these cool innovations for Bitcoin can’t be done with Bitcoin’s present architecture. Moreover, the current number of Bitcoin transactions per block has just about maxed out at ~1800. This has resulted in something called the Scaling Debate, which centers about the best way to scale the Bitcoin blockchain. Upgrades to the blockchain must be done through consensus where miners mine new types of blocks, institutions running nodes approve of those new blocks, and users continue to create transactions that are included in new blocks (or else find another cryptocurrency). Before any of that can happen, developers have to write the code that miners, validation nodes, and users will run.

Right now, there is a big political fight that could very briefly be described as between users who support the most common implementation of the Bitcoin wallet and node (known as Bitcoin Core) and those who generally oppose that implementation and the loose group of developers behind it. I certainly am not here to take sides, and in fact it would probably have some long term benefits if both groups could go their separate ways and have the market decide which blockchain consensus rules are better. However, there is not much incentive to do that, as there are network effects in Bitcoin and any chain split would reduce the value of the entire ecosystem. The network effects would likely mean any two-chain system would quickly collapse to one chain or the other. No one wants to be on the losing side, yet no side can convince the other, and so there has been political infighting and digging in, resulting in the current stalemate.

There will eventually be a conclusion to this stalemate; there is too much money on the line to avoid it. Either the sides will figure out a compromise, the users or the miners will trigger a fork of the chain in some way and force the issue, or eventually a couple years down the road another cryptocurrency will overtake Bitcoin as the most prominent store of value and widely used blockchain. A compromise would obviously be the least costly, a chain split would be more expensive, but could possibly solve the disagreement more completely than a compromise, while another cryptocurrency winning would be by far the most expensive and damaging outcome. All development and code security that went into Bitcoin would have to be redone on any new crytocurrency. Nonetheless, Litecoin just this week seems to have approved of Segregated Witness, the code piece that is currently causing the Bitcoin stalemate. If Bitcoin’s stalemate continues for years, Litecoin is going to start looking pretty great.

Obviously it’s disappointing that even a system built on trustless transactions can’t avoid the pettiness of human politics, but it’s a good case study demonstrating just how pervasive and pernicious human political fights are. Ultimately, because cryptocurrencies are built in a competitive market, politics cannot derail this technology forever. And when the technology does win out, the impact on the word will be revolutionary. I just hope it’s sooner rather than later.

What is Postlibertarianism? v2.0

When I started blogging here about 18 months ago, I knew that I was having trouble identifying myself as exactly “libertarian”, despite that being my primary blogging perspective for years before that. I’ve mapped out important parts of this “new” position in previous posts, but now I think it would make sense to put everything in one place. This post is labeled “2.0” since former postlibertarian.com blogger Joshua Hedlund defined it pretty well in 2011. This is a more in depth analysis.

As we approach the time when free trade is the heretical advice rather than the obvious logical one, it’s time to brush up on our free trade arguments. Here’s an interesting one: would you ban new technology to save the jobs tied to the technology it replaces? Would you ban light bulbs to save candlemakers? Cars to save horsebreeders? It’s a ridiculous proposition to freeze the economy at a certain point in time. Well, there’s no economic difference between new technology and free trade. In fact, we can treat international trade as a fancy machine where we send corn away on a boat and the machine turns the corn into cars.  

And speaking of free trade, this is the economic modeling for why a tariff is unequivocally inefficient. One of the impacts of a tariff, by the way, is an increase in the market price of a good. Anyone saying that a tariff won’t have negative effects on consumers is just plain wrong.

The excellent open source encrypted messaging app Signal is so useful, it has to avoid having its application servers blacklisted by oppressive regimes. It uses a workaround of having encrypted connections through content delivery network, in this case, Google itself. Moxie Marlinspike, the creater of Signal says “Eventually disabling Signal starts to resemble disabling the internet.”

One of the biggest problems with Trump I pointed out last year was the total unknown of his policies. He keeps changing his mind on almost every issue, and when he does speak, he wanders aimlessly, using simplified language that is more blunt and less precise. Fitting right into this pattern, Trump has taken to Twitter for much of his communication, even since winning the election. Twitter is a short and imprecise tool for communication, and this New York Times article shows just how much uncertainty Trump creates with his tweets.

Related: Bill Perry is terrified of increased nuclear proliferation. The article is a little alarmist, but it’s worth remembering that nuclear war was a real threat just 30 years ago. It should not be taken for granted that nuclear war will never occur, and Trump seems the most likely of the post-Soviet presidents to get involved in a confrontation with a major nuclear power.

Scott Alexander reveals his ideal cabinet (and top advisers) if he were president. It’s not only remarkably better than Trump’s, it’s probably better than any cabinet and appointees we’ve ever had (Bernie Sanders notwithstanding). Highlights include: Alex Tabarrok as head of the FDA, Scott Sumner as Chairman of the Fed, Charles Murray as welfar czar, Peter Thiel as Commerce Secretary, and Elon Musk as both Secretary of Transportation and Energy.

Speaking of cabinets, George Will details just how out of touch soon-to-be-Attorney General Jeff Sessions is, recounting his 2015 defense of unlimited civil asset forfeiture, a procedure by which the government takes cash and property from civilians who have been convicted of no crime and therefore have no recourse or due process protections. Don’t buy into the story that all of Trump’s appointees are horrific and terrifying; there is a gradient of his cabinet appointments depending on their authoritarian tendencies and the importance of their department, and unfortunately Jeff Sessions as Attorney General is by far the most concerning.

Missed this earlier last year, and worth keeping in mind as BuzzFeed gets hammered this week over their publishing of an unverified dossier: apparently the FBI already has daily aerial surveillance flights over American cities. These seem to be for general investigative use, not vital national security issues: “But most of these government planes took the weekends off. The BuzzFeed News analysis found that surveillance flight time dropped more than 70% on Saturdays, Sundays, and federal holidays.” 

Speaking of BuzzFeed and the crisis of “fake news”, which itself may not even be anything compared the crisis of facts and truth itself, Nathan Robinson has an excellent take on the matter (very long read). With the lack of facts in the election, the media and Trump’s critics generally have to be twice as careful to rebuild trust in the very concept that objective truth exists and can be discussed in a political context.

Government regulations have hidden, unexpected costs. These regulations hurt people regardless of their political affiliations, as a Berkeley professor found out when trying to evict a tenant that refused to pay rent. California’s rather insane tenant laws mean that serial rent-cheaters can go from place to place staying rent free for months at a time.

I’ve often thought about the right ordering of presidents from best to worst, taking into account a libertarian, liberty-promoting approach. One difficulty is the non-comparability of presidents separated by centuries. However, this blog post from 2009 actually does a nice job of scoring the presidencies. I don’t agree with each one, but it’s a rough categorization that makes sense. It even gave me an additional appreciation for Ulysses Grant, who I figured was mostly president by the luck of being the general in charge when his army won the Civil War. Other highlights include William Henry Harrison scoring 11th, thus beating over three quarters of the competition despite only being in office for a month. I feel like I could have found more worse things on Andrew Jackson, and in general I feel like I agreed with the list more the closer I got the end.

Jeffrey Tucker at FEE has a nice article about the difference between spreading ideas and actual economic production of goods. His thesis is that we have much less control over the developing of ideas than we do of developing normal rivalrous goods. And since libertarians are pretty solid at grasping the idea that the production of goods cannot be controlled from the top down, we should also acknowledge that top-down approaches to developing ideas are even more preposterous, especially in the digital age of decentralized information. I’ve thought about this a fair amount considering I like I blogging but I’m well aware few people read this blog. The simplest way to restate Tucker’s point is that you have to have good ideas more than good distribution. I don’t know if that’s an accurate take, but certainly good ideas are the single most important part of spreading your ideas.

There’s a saying on the internet that “Democracy is two wolves and a lamb voting on what to eat for lunch”. The 2016 election is excellent demonstration of just how poorly democracy can fail, but what our all alternatives. How about Futarchy? This is Robin Hanson’s idea to improve public policy: “In futarchy, democracy would continue to say what we want, but betting markets would now say how to get it. That is, elected representatives would formally define and manage an after-the-fact measurement of national welfare, while market speculators would say which policies they expect to raise national welfare.” Let’s hold a referendum on it; those seem to work out.

Bitcoin has been on the rise in recent months. So have other cryptocurrencies. But rather than focus just the price of the cryptocurrency, why not look at the total market valuation of those currencies? Sure, you might have heard that Bitcoin was up to $1000 again recently, but did you know that its total market cap is ~$13 billion? At the very peak of the Bitcoin bubble in 2013, all Bitcoins together were valued around $13 billion, but only for a matter of days. This time Bitcoin has kept that valuation for over 3 weeks. With more markets and availability, Bitcoin is becoming a real alternative for people whose national currencies have failed them.

Gary Johnson selected former Republican Massachusetts Governor William Weld  to be his running mate. This was pretty surprising for Libertarians considering Weld isn’t really a well-known libertarian guy.  Obviously, the Johnson campaign hoped not to repeat the failings of Jim Gray who was essentially unknown to the national media. During the Libertarian Party convention this weekend, the delegates selected both Gary Johnson and Bill Weld opting for pragmatism rather than party purity.  This is some election year when the libertarians are more reasonable than the Republicans and Democrats.

With 2 former Republican governors on the ticket, the Libertarian Party is now poised to be a real third party alternative. This could be a huge year for them, even if they don’t win. Remember, from our archives, if you reach 5% of the popular vote in a presidential election, you are entitled to real money in the next cycle (the irony of Libertarians accepting Federal handouts not withstanding).

Nicholas Kristof has a follow up to his column “A Confession of Liberal Intolerance” where he condemned the intolerance of progressives especially in the university. Apparently, the left universally scoffed at the thought of tolerating conservatives…which essentially confirmed his point.

The EFF is shutting down their canary watch program after a year. I have previously discussed the importance and usefulness of warrant canaries. It seems the EFF has decided it isn’t worth the effort to keep track of all the notices because they seem to change too much from post to post.  These aren’t bad reasons, but it is a little concerning. It seems likely that you’ll just have to stick to the default that any website you visit has received national security letters asking for information.

Jason Brennan at Bleeding Heart Libertarians on the difference between Ignorance, Misinformation, and Irrationality in democracies.  Essentially ignorance isn’t exactly the problem in democracies, since if everyone is equally ignorant, then the non-ignorant people will be able to make rational decisions; there is no bias for the ignorant people since they have no opinion. Misinformation can be a problem though, if most people are misinformed, they will make poor decisions. But even if people are misinformed, having a deliberative discussion will help as rational logic should triumph. But irrationality is a serious problem, since even discussions would just spread more misinformation. This relates to the thesis of Bryan Caplan’s book The Myth of the Rational Voter (Wikipedia, full text for free).  I look forward to reading Brennan’s new book, iconoclastically titled Against Democracy.

Tangentially related: John Oliver has a segment on the flaws of the primary system. Unfortunately, he sort of glosses over the assumption that they need to be more democratic, but do they? He says this time we “got lucky” in that the candidates with the most votes were the ones actually chosen, but we need to change things in the future. I disagree; the candidates we did choose are awful. If the system is working now, making it work better won’t help anything. Check out my previous post for more on this, and forward it to John Oliver if you get a chance. Better than reforming the primary system, let’s try making more parties more viable with some proportional representation in the House of Representatives!

Why Bernie doesn’t quit: Polisci 101 analysis of Bernie Sanders’ intentions. Basically, he wants to stop Hillary from turning towards the center, since he wants the Democratic party to be very a progressive Social Democrat party. This is also the reason that anyone who’s not a Social Democrat wants Bernie out of the race.

Ilya Shapiro at the Cato Institute, who knows his stuff pretty well, called Donald Trump’s list for replacing Justice Scalia’s SCOTUS seat “exceptional”. This is good news in that a Trump presidency would at least have this going for it. I don’t know if all this would make him a better choice than Clinton, but it is a big deal, at least to me.  Doubtful if this alone would be enough to unite all Republicans around him.

Nick Gillespie has two solid blog posts. One is a great overview of a recent Foreign Relations Committee Hearing and the constrasting views of Marco Rubio and Rand Paul.  Paul, we should note, won his primary to stand for reelection for his Kentucky Senate seat. This should largely guarantee his victory (PredictIt doesn’t have a market yet but PredictWise has it at 90% Republican).  The other post discusses how Obama’s new overtime regulations are going to harm workers by reducing hours, workers, or both.

Meta-blog post. Do you need more economics blogs? Here is a giant list of them. They’re vaguely ordered by popularity, and you shouldn’t just dismiss it because Paul Krugman is first; there’s a lot of good blogs I didn’t know about.

Dylan Matthews at Vox makes the case for getting rid of the TSA. Doesn’t even mention the financial cost savings (their budget is $8 billion, and cost of time is at least that).

Scott Sumner on the problems with government policy responses to crises. Scott also did a much better job predicting the economy than the Fed. Takeaway: please, please institute prediction markets for the basic macroeconomic indicators.

Cool YouTube video on computational complexity and the P vs NP problem.

What are the components of airline ticket prices? Great YouTube video explanation.

All the Scott Alexander: Apparently good kindergarden teachers have massive effects on income decades later, but no lasting effect on test scores. There really bizarre studies and all I can tell is that education research is hard.

As part of his ongoing philosophy of niceness and tolerance in society, and relating to my post on tolerance, Scott discusses more on tolerance and coordinated vs uncoordinated meanness.

Scott also has a great post on his experience in the Irish health system, related to the UK junior doctors’ strike.  There are serious barriers to entry to the US medical system because the benefits are so high if you become a doctor. In UK, this is not true, since the state regulates how much doctors can make, so of course many doctors are leaving the UK and Ireland for places where the pay is less regulated. Scott says he’s not sure how to solve labor disputes, but if you have a freer market in hiring and payment, you don’t end up having labor disputes. The American system has problems as well, and if the barriers to entry could be reduced

And finally: Scott Alexander’s review of Albion’s Seed, and his analysis of the importance of culture in determining beliefs.

Apparently non-technical people don’t know this, but Craig Wright isn’t Satoshi Nakamoto. He had an “exclusive” interview with several media outlets discussing how he was really the inventor of Bitcoin. But if you read the story pretty quickly, you notice he doesn’t provide a signature with Satoshi’s private key (the reddit and Hacker News threads found he stole a signature from a transaction in one of the early blocks), and he doesn’t move any of Satoshi’s money to a publicly declared account. Those are very easy ways to prove he is Satoshi Nakamoto, and he didn’t do them, instead relying on some weird demonstration directly to a journalist. I would have guessed most people would have figured he was lying (he has a weird history as well), especially because Satoshi Nakamoto has gone to great lengths to protect his identity, and this guy is clearly trying to get attention. But several news outlets printed it as true. Gavin Andresen, the lead developer of Bitcoin, has declared that he has seen proof, but he hasn’t told us what the proof is.  But you shouldn’t need a really famous person to vouch for someone’s identity, that’s the whole point of Bitcoin; decentralized proof is easy and clear.
