Today I want to talk about code.
I know, this newsletter is for professional investors and not developers – why aren’t we talking about price? Don’t worry, we will further down. But things are evolving with Bitcoin technology that are worth keeping an eye on. While these changes have little to do with the short-term price movements, they are likely to play a significant role in bitcoin’s long-term value proposition.
Before we go into more detail about why these are significant, let’s look at why Bitcoin development matters.
The idea of changes to the Bitcoin protocol will be surprising to many. I mean, doesn’t it just, you know, work? Isn’t one of its strengths that you can’t change the code? These highlight two misunderstandings about the technology and its potential.
Bitcoin’s code has been chugging along for over 10 years now, but it has undergone a few changes. In the early days, there were frequent bugs that Bitcoin’s pseudonymous creator Satoshi Nakamoto and collaborators would fix. And old-timers will remember the “civil war” of 2017 around various scaling options that went to the heart of what the community wanted Bitcoin to be. The result was a change to the Bitcoin code to amplify block capacity, while dissenting opinions branched off to form a “new” Bitcoin blockchain, Bitcoin Cash.
There’s also steady work on functionality enhancements, such as enabling sidechains or smoothing information exchange. And compatibility issues and other minor bugs require constant attention. Like all technologies, if Bitcoin is not maintained and frequently updated, it will wither.
As for how changes happen, anyone can make changes to Bitcoin’s code – it’s open source. Getting the changes implemented, however, requires network consensus, and that is extremely difficult to achieve. Imagine trying to get 20 people with different philosophies, political convictions, economic incentives and life goals to agree on a simple change. Now, multiply that by hundreds if not thousands, make the changes complicated, and you get an inkling of how hard it would be to implement a meaningful alteration. This protects the network from any change other than those the majority believe are beneficial to the entire ecosystem.
An important question is, who pays the developers that work on Bitcoin code?
In the early days of the Bitcoin network, almost all developer funding came from one source, the Bitcoin Foundation. Since then, other funders have entered the scene, including several companies dedicated to Bitcoin work, such as Blockstream, Chaincode Labs and Lightning Labs. Also involved are well-known crypto businesses such as Square Crypto, Coinbase, OKCoin, BitMEX and others, as well as not-for-profit organizations such as MIT’s Digital Currency Initiative and the Human Rights Foundation. In addition, many developers work on Bitcoin for free, out of passion.
Diversity in the backers of Bitcoin development matters, as it ensures that the network cannot be influenced by one set of priorities. This is why the Brink initiative announced this week is significant: It pushes the diversity of Bitcoin development even further.
Brink introduces an intriguing funding model. It aims to channel donations to developers from a range of sources, including individuals, companies and not-for-profits. Its initial funding comes from donations from investor John Pfeffer and crypto custodian Xapo founder Wences Casares, as well as the Human Rights Foundation and crypto platforms Kraken, Gemini and Square Crypto.
This form of sponsorship could be appealing to individuals and companies that want to support Bitcoin development but don’t want to have to choose specific individuals to fund. The organization has applied for the charitable 501(c)(3) designation in the U.S. so donations can be tax-exempt.
Another big step is Brink’s focus on training new developers, to ensure a steady stream of qualified and diverse contributors well into the future. This bodes well for the network’s long-term resilience and growth.
The second significant news item of the week highlighting the importance of the underlying technology concerns the Taproot upgrade, which will enhance the network’s smart contract functionality as well as introduce some privacy features. Bitcoin mining pools representing over 54% of the network’s current hashrate have signaled support. This is a strong step towards implementation (although there is yet some way to go – no change to the network is without controversy, no matter how popular the actual change is.)
This is significant not just because of the specific changes Taproot will introduce. It also shows that Bitcoin’s use cases are constantly evolving, and that itself is a value proposition. In other words, if you think Bitcoin is a powerful technology now, just wait.
As an example of how Taproot could influence bitcoin’s value, let’s look at what smart contract functionality means. Bitcoin’s program is relatively simple. It can do few things, but it does them well. Ethereum, on the other hand, is complex, but it can support the execution of a wide range of “smart contracts,” or decentralized applications.
While Bitcoin will never rival Ethereum in flexibility (nor does it want to – the more complex the program, the greater the potential attack surface), some modest improvements could improve its utility as a store of value. For instance, imagine that accountability of ownership could be programmed to enable bitcoin to be more effectively used as collateral.
They could also enhance its use as a medium of exchange. A proposed new type of verification signature could make layer 2 transactions easier and cheaper. Taproot also introduces some features that could encourage more use by masking the type of transaction (not its send/receive addresses), which would offer more privacy.
While it is convenient to think of Bitcoin as a perpetual machine that just keeps running, we shouldn’t lose sight of the work involved in making that so. The more developers working on keeping Bitcoin clean and efficient, the more resilient the protocol, and the more likely it is that key improvements can be implemented carefully.
And the more diverse those developers are in terms of backgrounds and incentives, the less likely it becomes that Bitcoin could fall into the same trap as many of today’s technology networks: built by a few, for a few.
It’s also moving to see such a wide range of contributors involved in maintaining a “common good,” even though a direct path to profit is not clear. This is about more than open-source tinkering. It’s about building a new system that all involved believe is an answer to fundamental questions the world is just now waking up to.
Time to serve
This week U.S. President-elect Joe Biden announced his intention to nominate former Federal Reserve chairman Janet Yellen to head the U.S. Treasury, and may name former Commodity Futures Trading Commission Chair Gary Gensler to become deputy treasury secretary, according to reports.
Treasury appointments are significant for the crypto industry in that the department could shape how some of the main U.S. financial regulators approach crypto assets.
Yellen has said in the past that she is not a fan of bitcoin (my colleague Nik De has summarized her views here) but supports blockchain and cryptocurrency innovation.
Gensler has demonstrated deeper expertise and enthusiasm. He testified before Congress about cryptocurrency and blockchain on multiple occasions, pushing back against comparisons with Ponzi schemes and declaring that the still-unlaunched libra token met the requirements of being a security under U.S. law. Late last year, he even wrote an op-ed for CoinDesk.
Gensler is currently heading up Biden’s financial oversight transition team, which also includes four other cryptocurrency and blockchain experts:
Chris Brummer is a law professor and the faculty director of Georgetown University’s Institute of International Economic Law, author/editor on a seminal book on cryptoassets, and host of the excellent Fintech Beat podcast. He also testified before the U.S. Congress regarding the libra project, and was nominated to serve as a commissioner on the CFTC under President Obama, although the nomination was reversed after the 2016 election.
Simon Johnson is an economist and professor at the MIT Sloan School of Management, where he supervised blockchain research and taught a course on the topic. He was part of the Congressional Budget Office’s Panel of Economic Advisers from April 2009 to April 2015. Johnson has also co-authored a paper about the extensive impact blockchain technology can have on the financial world, and served on CoinDesk’s advisory board, penning this op-ed in 2018.
Mehrsa Baradaran, a University of California at Irvine School of Law professor, specializes in banking law and also testified as an expert witness at a Senate Banking Committee hearing on the impact of digital currencies on financial inclusion, and at a House Financial Services Committee hearing on regulatory frameworks.
Lev Menand, one of the original creators of the digital dollar concept, is an academic fellow and law professor at Columbia University. He served as a senior adviser to the deputy secretary of the treasury in 2015-16, has also worked as an economist at the Federal Reserve Bank of New York’s bank supervision group, and helped with a provision detailing the digital dollar in crisis relief bills from the House of Representatives drafted back in March.
Having stewards of U.S. currency regulation that are well-informed about cryptocurrency and blockchain is encouraging because it makes innovation-killing regulation less likely. Furthermore, official support for the exploration of new solutions to financial barriers, including blockchain-based assets, is likely to encourage both progress on regulatory clarity, and further investment in the crypto industry as a whole.
However, a statement from current U.S. Treasury Secretary Steve Mnuchin offset the resulting market optimism, triggering concern that onerous rules might be pushed through from his office before the end of the year. Former National Security Adviser John Bolton’s recent book revealed that President Trump had instructed Mnuchin to “go after” bitcoin. And earlier this year, Mnuchin said that FinCEN, the nation’s financial crimes watchdog, was preparing to roll out some “significant new requirements” around cryptocurrencies.
So, some innovation-killing regulation may get rushed through before the transition. Crypto exchange Coinbase’s CEO Brian Armstrong tweeted this week that he’d heard rumors Treasury was planning to rush out regulation limiting the use of self-hosted cryptocurrency wallets.
This would be bad news for crypto asset use cases such as decentralized finance and merchant applications, and would put U.S. cryptocurrency users in a “walled garden,” effectively negating its core value of resistance to censorship and seizure. It would also force many users to go “offshore” for such services, weaking both the protective oversight from U.S. regulators and the role of the U.S. as a financial innovation hub.
Anyone know what's going on yet?
The S&P 500, Nasdaq and even the FTSE 100 saw further gains this week, which I still find bewildering.
It looks like I’m not the only one: The European Central Bank, International Monetary Fund and Federal Reserve have all warned this month about shocks to the market should the coronavirus situation continue to worsen. And it looks like it is doing just that, given the latest confirmed case statistics. The latest news on vaccination progress is hopeful, yet expectations are likely to be disappointed by logistical complications and revised efficacy estimates, and the markets seem to be pricing in a strong economic recovery in the short term. A lot can happen to delay that recovery, and not just further surges as Thanksgiving and Christmas throw us together and winter temperatures push us indoors. There’s also the looming possibility of a hard Brexit, which will hit both the U.K. and Europe.
That doesn’t mean that markets won’t keep at the laughing gas, though. If there’s bad news, the belief seems to be that governments will support the markets. If there’s good news, then obviously it’s not discounted. Obviously.
Gold also defied expectations this week, dropping to its lowest point since July as (according to analysts) investors decided now was a good time to move into risk assets and double down on the economic recovery bet. Yes, you read that right.
Bitcoin, which at times trades with gold and at times trades as a risk asset, continued to soar, reaching an annual high of almost $19,375 and only just depriving an expectant crypto community from a new all-time-high (ATH) celebration. (According to CoinDesk’s Bitcoin Price Index, the ATH is $19,783. Here is a good explanation of why there is confusion over what the ATH actually is.)
The bitcoin price started to correct early on Wednesday, and once the U.S. markets closed for the Thanksgiving holiday the correction turned into a rout, unwinding its gains for the past 10 days (at time of writing – at this pace, things could have radically changed by the time you read this).
In searching for the reasons behind the recent bitcoin run-up (before this week’s slump), many pointed fingers at the institutions. While we have been hearing for years now about the fabled institutional “wall of money” poised to rush in and push BTC prices to stratospheric levels, there are some signs that institutional interest is growing.
- The CIO of Fixed Income of BlackRock, the largest investment manager in the world, said on CNBC last week that bitcoin could take the place of gold to a large extent, because crypto is “so much more functional than passing a bar of gold around.”
- According to two Form D filings, Galaxy Digital’s bitcoin funds raised $58.7 million in their first year, with $55 million flowing into an institution-focused fund.
- Analysts pointed out that most of the trading volume occurred in U.S. hours.
- The past three 8-K filings for Grayscale Investments (owned by DCG, also the parent of CoinDesk) show new accredited investor inflows of over $823 million. (Source: FactSet)
- In a recent investment note, JPMorgan speculates that bitcoin’s failure to revert to its mean price in recent weeks is a sign that momentum traders such as commodity trading advisers (CTAs) have had a shrinking role in the market relative to institutions.
- Zerohedge shared a chart that shows that Deutsche Bank includes bitcoin in the asset groups its research team follows for investors.
The demand growth is not just coming from institutions:
- According to Marcus Swanepoel, CEO of crypto exchange Luno (owned by DCG, also parent of CoinDesk), retail trading volumes from South Africa, Malaysia, Nigeria and Indonesia have trebled over the past month.
- Dan Morehead, CEO and founder of fund manager Pantera Capital, believes that PayPal is behind the rally, buying almost 70% of new bitcoin supply on behalf of its retail users.
In an interview on CNBC, PayPal CEO Dan Schulman said he believes bitcoin’s usefulness as a currency will ultimately prevail over the buy-and-hold ethos. TAKEAWAY: He has invested his company’s money in these beliefs, promising PayPal users the ability to use cryptocurrencies in approximately 28 million businesses as of early next year. While many of us will splutter and say “but who would want to spend a store of value?!,” we should remember that some regions don’t have access to convenient payment rails. For many, cryptocurrencies may be a more convenient online payment method than fiat. And the applications that could be built on top of public blockchains to enhance this could end up supporting both innovation and cryptocurrencies’ overall value.
U.S.-based crypto exchange Coinbase no longer allows margin trading, in response to recent regulations by the Commodity Futures Trading Commission. TAKEAWAY: This is a setback for institutional participation on Coinbase – institutions want leverage, and will move to where they can get it.
In this compelling article, my colleague Ian Allison looks at the emergence of a strong bitcoin mining industry in North America, encouraged by the access to capital markets, regulatory stability and the relatively low energy and hosting costs. TAKEAWAY: This is significant for two main reasons: 1) the diversification of the mining base strengthens the protocol’s resilience against political interference, and 2) the enhanced access to capital markets is likely to encourage even more investment in network maintenance. The greater the number of miners working on maintaining the network, the greater its security.
New York-based investment management firm VanEck has launched a bitcoin exchange-traded-note on the Deutsche Boerse Xetra. TAKEAWAY: This will be the third exchange-traded product to list on Xetra, one of the largest electronic trading platforms in Europe, with a broad international reach (around 50% of its trading participants are from outside Germany). Diversity of choice is good for both investors and market maturity.
Canada-based investment firm Cypherpunk Holdings (listed on the Canadian Securities Exchange with the very cypherpunk-ish symbol of “HODL”) has sold its positions in monero and ether and increased its bitcoin holding by almost 280%. TAKEAWAY: I do not have insight into their reasoning. I share this news with you because the strong bitcoin conviction demonstrated by this change, combined with the hint in their ticker symbol, is interesting.
