Blockchain-Bitcoin-Cash-and-Antitrust-300x180

Author: Luis Blanquez

Following DOJ’s remarks on blockchain, it was only a matter of time until antitrust law and the unstoppable blockchain world would meet in court. And it finally happened some months ago in the complex Bitmain case.

In this case a cryptocurrency developer and mining company sued Bitcoin Cash miners, developers, and exchange operators for violating of Section 1 of the Sherman Act and Section 4 of the Clayton Act. It accused them of manipulating a network upgrade to take control of the Bitcoin Cash blockchain. The Court dismissed the Amended Complaint twice (the last one with prejudice), for failing to plausibly show a conspiracy to hijack the network and centralize the market, an unreasonable restriction of trade, and antitrust injury.

  1. Blockchain and cryptocurrencies

Blockchain is such a complicated technology that just the simple task of defining it would require a much longer article. But the Southern District Court of Florida did a great job explaining in very simple terms what these two concepts––blockchain and cryptocurrencies–– are:

Cryptocurrency is a form of digital currency that trades in currency markets. The Satoshi Nakamoto whitepaper, published in October 2008, launched the idea of this “peer-to-peer” version of electronic cash that allows online payments from one party to another, independent of any financial institution. The Whitepaper coined the term “Bitcoin”, and today Bitcoin and Bitcoin Cash are different forms of cryptocurrency.

Cryptocurrencies are a “permissionless” system that rely on a network of decentralized encrypted public ledgers that document all digital transactions, known as a “blockchain”. The blockchain is a series of blocks, which are units of accounting that record new transactions in cryptocurrency. Confidence and trust in the accuracy of the transactions in the blockchain is possible because the decentralized ledgers are identical and continuously updated and compared.

The system has mechanisms that allow for consensus on the validity of the blockchain. One is “Proof-of-Work”, which is designed to eliminate the insertion of fraudulent transactions in the blockchain. Also, the “main chain” (normally, the longest chain) at any given time, is whichever valid chain of blocks has the most cumulative “Proofs-of-Work” associated with it. A consensus being reached on the longest blockchain is essential to the integrity of the network.

New cryptocurrency is created through a process called “mining”. Miners compete to “mine” virtual currencies by using computing power that solves complex math puzzles. The computer servers that first solve the puzzles are rewarded with new cryptocurrency, and the solutions to those puzzles are used to encrypt and secure the currency. The awarded currency is then stored in a digital wallet associated with the computing device that solved the puzzle.

  1. The Bitmain case

In a nutshell, this case is about how certain mining pools, protocol developers and crypto-exchange defendants allegedly colluded to manipulate a network upgrade by creating a new hard fork, taking control of the Bitcoin Cash cryptocurrency. In the end, however, the court concluded that the plaintiff ––a protocol developer of blockchain transactions and mining cryptocurrencies––, failed to (i) show a plausible conspiracy, (ii) define any relevant product market to prove an unreasonable restriction of trade, and (iii) show any antitrust injury.

The Parties

As Konstantinos Stylianou effectively explains in his article What can the first blockchain antitrust case teach us about the crypto economy?, in the cryptocurrency world it is important to understand what the different players are and how they are connected in the market: investors, mining pools (groups of miners that combine their mining resources), crypto-exchanges, and protocol developers. We highly recommend his article.

The plaintiff, United American Corporation (UAC), is a developer of technologies for both the execution of blockchain transactions and mining cryptocurrencies. One of them is called BlockNum, a distributed and decentralized ledger technology that allows the execution of blockchain transactions between any two telephone numbers regardless of their location, eliminating the need for cryptocurrency wallets. The other one is called BlockchainDome, which provides a low-cost energy-efficient solution for mining cryptocurrency. UAC built four domes in total that operate over 5,000 Bitcoin Cash-based miners, investing more than $4 million in technology.

On the flip side, there are three different categories of defendants:

  • The mining pools: (i) Bitmain Technologies operate two of the largest Bitcoin Core and Bitcoin Cash mining pools in the world: Antpool and BTC.com. It is also the largest designer of Application Specific Integrated Circuits (“ASIC”), which are chips that power the Antminer series of mining servers––the dominant servers mining on a number of cryptocurrency networks, including Bitcoin and Bitcoin derivatives; (ii) Wu, CEO of Bitmain Technologies and one of its founders; and (iii) Ver, founder of Bitcoin.com, which provides Bitcoin and Bitcoin Cash services.
  • The crypto exchanges––Kraken and its CEO Jesse Powell––which operate exchanges on which Bitcoin, Bitcoin Cash and other cryptocurrencies are traded.
  • The protocol developers Shammah Chancellor, Amaury Sechet and Jason Cox who––similarly to UAC––, work on the development of the software to execute blockchain transactions and mining of cryptocurrencies.

The Alleged Antitrust Conspiracy

Summarized from the briefing:

Bitcoin Cash (or “BCH”) emerged as a cryptocurrency from the original Bitcoin Core (or “BTC”) on August 1, 2017, as a result of a “hard fork”. A hard fork is a change to the protocol of a blockchain network whereby nodes that mine the newest version of the blockchain follow a new set of rules, while nodes that mine the older version continue to follow the previous rules. Because the two rule-sets are incompatible, two different blockchains are formed, with the new version branching off.

The 2017 hard fork resulted from a dispute over Bitcoin’s utility: whether it should primarily be used to store value or conduct transactions.

(Note: BTC’s resistance to this significant attempt to fork it further strengthened it by demonstrating that it can overcome an attack of this type. If BTC were subject to significant forks that change its nature, it would not have the trust it has now as a store of value. This and other attacks on BTC actually strengthen it—Bitcoin is Antifragile in this way).

I suspect that Antitrust DOJ head Makan Delrahim and I have had a similar reading list lately. And I am not even referring to any sort of antitrust books, like, for example, Steve Cernak’s book on Antitrust in Distribution and Franchising.

Let me explain.

I read, with great interest, a speech that Assistant Attorney General Makan Delraihim delivered on August 27, 2020 to the Conference on Innovation Economics in Evanston, Illinois (well, virtually).

His two topics were blockchain and Nassim Taleb’s concept of antifragility.

As a consistent reader of this blog, I trust that you already know that I am a big fan of Nassim Taleb and, particularly, his book, Antifragile: Things that Gain from Disorder. Indeed, a re-reading of Antifragile inspired an earlier article about Iatrogenics. If you haven’t read Antifragile, you should, right away.

My interest in blockchain, Bitcoin, and other cryptocurrency systems like Ethereum is relatively recent. But—like many before me—a little bit of knowledge has created an insatiable appetite for more. I am making my way down the rabbit hole, as they say.

Let’s dig in and talk about what the Department of Justice thinks about both antifragility and blockchain.

Antifragile

What does the term “antifragile” mean?

You might think that robust is the opposite of fragile. But those of us that have read Taleb know that isn’t true. Something that is fragile is likely to break or weaken from stress, shocks, or variability. If something is robust, it will resist this stress, shock, or variance.

But what you really want during times of stress (or, really, just over time), is antifragility. If you are antifragile, you improve from stress, shocks, and variance, which are inevitable, especially as time passes.

The human body is, in some ways, antifragile. Lifting weights, for example, creates a stressor on the muscles and surrounding tissues, which cause, ultimately, an increase in strength. So make sure you get your deadlifts in this week.

Antifragile is the opposite of fragile and it is better than robustness.

There is a lot more to antifragility than this. Indeed, there is an entire book about it (and, really, a set of books—Incerto). I urge you to read more—it might change your life.

Earnest Hemingway understood antifragility when he said in A Farewell to Arms that “the world breaks everyone and afterward many are strong at the broken places.” The next line is just as important for reasons you will understand if you read Antifragile: “But those that will not break it kills.”

//ws-na.amazon-adsystem.com/widgets/q?_encoding=UTF8&ASIN=1476764522&Format=_SL250_&ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=suchealif01-20&language=en_US

So, what does antifragility have to do with the Department of Justice and antitrust?

Assistant Attorney General Makan, in his speech, emphasized that “the Antitrust Division has made protecting competition in order to advance innovation in the private sector one of our top priorities,” and that the Division wants to “ensure that antitrust law protects competition without standing as an impediment to rapid innovation.”

He then introduced the concept of antifragility and acknowledged that the pandemic can certainly be described as a “shock” producing a “wide array of trauma.” But with that harm comes an opportunity—“if we rise to the challenge of being antifragile, there is also an opportunity for tremendous growth.” More specifically, “[c]ritical innovations and technological developments often result from the kind of extraordinary experimentation the pandemic has made necessary. We have the opportunity to embrace antifragility, to delve into the experimentation and trial and error that drive growth, and to make ourselves better.”

According to AAG Makan, “[o]ur goal at the Antitrust Division is to extend the spirit of innovation beyond our latest efforts to combat the pandemic and protect competition—ultimately, to become antifragile.”

The market system—competition—is, of course, an antifragile system because it improves with variance over time, including shocks and stresses. As problems arise, the market provides solutions. As new preferences arise, the system meets those preferences. As demands for certain products or services decrease, resources move away from those areas. Indeed, the “heart of our national economy has long been faith in the value of competition.” And the purpose of the antitrust laws is to protect that competition.

I am pleased to read the DOJ Antitrust leader expressly affirm those values and I have no doubt that he believes them—you can’t read and quote Taleb and not be affected.

But let’s remember that large central government is not typically the friend of antifragility. Indeed, government interference is more likely to distort incentives and the market’s ability to adjust to stressors. It can also lock-up parts of the system and increase fragility.

When a knocking on your door is followed by a shout of “I am from the government and I am here to help,” your heart should feel fear not relief.

I view the antitrust laws, if applied with restraint, as similar to contract, property, and tort laws. They provide the rules of the game that allow the market to prosper. Failure to apply any of them uniformly or fairly harms the beneficial potential of markets and competition. But over-applying them does the same. Like much of life, sometimes the answer is complicated and doesn’t fit into a single tweet.

Government enforcers can, however, stay on the right track if they have in their mind the rule that doctors often forget: “First, do no harm.” Antitrust enforcement, like medical intervention, can be iatrogenic.

Blockchain, Bitcoin, and Cryptocurrency

The DOJ Antitrust Division’s attorneys have formally educated themselves on blockchain and other technologies. And, like me, once they started learning about it, they probably realized what a big deal it truly is.

My worry, frankly, is that the government is going to somehow screw it up.
