Consensys is the center of the Ethereum ecosystem. Its founder, Joe Lubin, is the man who’s made more money from Ethereum than anyone.

Consensys makes the immensely popular MetaMask crypto wallet. They offer a swaps service and a staking service through MetaMask.

Anyway, Consensys got a Wells notice of impending enforcement action from the SEC on April 10. The SEC thinks Consensys is operating as an unregistered broker-dealer by making money on the MetaMask Swaps and MetaMask Staking products.

To head this off, Consensys is preemptively suing the SEC first! [Blog post; complaint, PDF; docket]

Consensys wants a ruling that:

  • MetaMask Swaps does not make Consensys a broker-dealer;
  • MetaMask Staking is not an offering of securities;
  • Ether (ETH), the native token of the Ethereum blockchain, is not a security.

It also wants an injunction against the SEC even investigating MetaMask Swaps or Staking, and against investigating the company’s sales of ETH in terms of ether being a security. And a pony would be nice too.

The complaint

The SEC has been investigating Consensys for two years. The agency first sent Consensys a letter in April 2022 advising them that they were investigating MetaMask. Then in September 2022, Consensys got another letter that the SEC was investigating staking protocols on the Ethereum network.

Consensys complains that it “did not have fair notice” of only two years.

The complaint was filed in the Northern District of Texas — Consensys used to be in Brooklyn, New York, but moved to Fort Worth sometime last year. 

Consensys has hired Wachtell, Lipton, Rosen & Katz, one of the best-known law firms on Wall Street. It’s the same firm Coinbase is using to fight back against the SEC. 

MetaMask

MetaMask is a self-custody crypto wallet that Consensys distributes free as a web browser extension. You can move ETH or tokens running on top of Ethereum, such as altcoins or NFTs, between blockchain addresses.

Two services that Consensys sells via MetaMask are MetaMask Swaps and MetaMask Staking. It even calls these “core features” — though Swaps was introduced in 2020 and Staking in 2023. 

MetaMask Swaps

Swaps lets you “communicate with third-party decentralized exchanges.” Consensys charges a 0.875% fee for use of the service. What does Swaps do?

MetaMask Swaps software itself does not execute transactions and never comes into possession of users’ digital assets. It simply displays pricing information collected from third-party aggregators and sends user commands to DEXs, which execute the transactions. 

Now, you might think this closely resembles a stockbroker buying and selling stocks for you and taking a fee for doing so.

In the world of conventional securities, facilitating trade in beneficial ownership rights in stocks whose owner of record is the Depository Trust and Clearing Corporation (DTCC) is also non-custodial. We still call this job being a “broker.”

But this only matters if any of the tokens are securities. Are they? Well … yes. Almost all of the tokens you can use on MetaMask would be considered securities under the Howey test. They were created as schemes to profit from the efforts of others. The SEC’s 2017 DAO Report and 2019 framework for investment contract analysis bludgeon this point home.

The SEC has settled or won in court in previous cases arguing that many tokens of this sort are securities — such as its actions against Bittrex, Terraform, and ShapeShift — so we expect that a complaint will name various tokens traded in Swaps and detail why they are securities.

Consensys admits that it’s helping customers buy and sell these tokens and it’s taking a fee for doing so. The SEC just has to show that some of the tokens are securities.

MetaMask Staking

MetaMask Staking lets you “stake” ETH to earn more ETH.

Ethereum doesn’t use proof-of-work mining like bitcoin — instead, it uses proof-of-stake. You put up a validator node with 32 ETH locked in it and you have a certain chance to generate a block that goes into the blockchain. If you do, you win the block reward.

Ethereum staking hits all of the elements of the Howey test of whether something is a security:

  • “an investment of money” — your 32 ETH stake
  • “in a common enterprise” — Ethereum
  • “with a reasonable expectation of profits” — the validator specification document literally says “verify and attest to the validity of blocks to seek financial returns” [GitHub]
  • “derived from the efforts of others” — promotion and management of the scheme by the Ethereum Foundation and money from the retail suckers who buy your ETH winnings.

The Ethereum Foundation, which determines how Ethereum works, is based in Switzerland. However, staking that involves a US entity would be under SEC jurisdiction.

Various companies have offered staking as an investment to institutional and accredited investors. That’s fine — but it’s not so fine when they offer it to ordinary mom-and-pop retail investors.

In June 2023, the SEC and ten state securities regulators came down on Coinbase for offering its staking product to retail investors. The SEC fined Kraken $30 million in February 2023 over its staking offerings. Kraken had to remove its staking product from the US market. 

Consensys offers its ordinary retail customers using MetaMask access to the Lido and Rocket staking pools. Consensys doesn’t mention it in the complaint, but they take a 10% fee for staking via MetaMask. [Consensys]

The complaint hammers again on the non-custodial nature of the staking service:

Like the rest of the MetaMask wallet software, the MetaMask Staking feature is entirely non-custodial; at no point does Consensys come into possession, custody, or control of a user’s tokens, nor can it alter in any way the user’s transaction instructions to the protocol. 

But that doesn’t matter — because they’re blatantly offering an investment scheme to retail investors and taking a 10% fee.

In fact, Consensys admits that it put a lot of work into the new staking mechanism, and the SEC subpoenaed information on this work:

They also seek detailed information concerning the role of Consensys, including its software developers, in a host of Ethereum Improvement Proposals related to the Ethereum Merge, the transition from a proof-of-work to a proof-of-stake validation mechanism. 

That is, Consensys themselves helped move the Ethereum network to its current very security-like operating mode, which is entirely different from the 2018 mechanism that wasn’t considered an investment contract.

Is ETH a security?

The complaint rants at length about whether ETH is a security, and even says that “the SEC now claims that ETH is a security subject to SEC regulation.”

This isn’t something the SEC has actually declared yet. What SEC chair Gary Gensler has done is suggest that ETH might possibly be a security now — particularly after Ethereum’s move to proof-of-stake in September 2022.

Consensys is outraged by this. The complaint cites lengthy historical evidence of the SEC and its commissioners telling the world that ETH is not a security. However, most of this dates back to 2018.

In 2018, Ethereum was running on a proof-of-work network, where crypto miners got rewards for spending electricity to guess a number and not for putting in funds.

Consensys notes the switch — but not how the payment model changed.

The crypto world is very good at going “la la la I can’t hear you” when obvious concerns such as this are raised early, then acting surprised when they suddenly become relevant. But crypto people were already talking in 2019 about the then-planned Ethereum staking really obviously being a security in the US, and both the SEC and the CFTC started looking into the question in that year. [Grant Gulovsen, 2019; CoinDesk, 2022]

If ETH is determined to have changed its operating model to now run as an offering of securities, that takes out Consensys’ entire business. It also undermines Lubin’s massive wealth. We’re surprised Consensys was dumb enough to even raise the question.

What happens next?

We’re not lawyers ourselves, but the expensive lawyers who wrote this complaint seem only to have been able to find the crayons that day.

Consensys admits upfront to most of what the SEC would need to nail them on MetaMask Swaps and Staking. The SEC would just need a ruling that tokens on Swaps were securities. On Staking, it looks like Consensys doesn’t have a case.

The extended table-pounding on the history of ETH leaves out how present-day staking works — that is, just like an investment contract. The SEC just needs to note the fact.

After that incredibly stupid Ripple ruling, we won’t say that Consensys can’t prevail here. We do think their chances of winning are incredibly thin, and the complaint leaves itself wide open to the SEC’s obvious responses.

Update 1: One possible reason for Consensys filing this bizarre complaint in the Northern District of Texas is that it’s likely to go to Judge Reed O’Connor, a George W. Bush appointee known for his history of such bizarre rulings that even the present Supreme Court has consistently knocked them back. O’Connor might plausibly go for the complaint’s good ol’ boy hollering about the evils of fed overreach.

Consensys is weirdly vague about precisely when they moved to Texas. There wasn’t a press release. CoinDesk says Consensys’ office is in a WeWork, though WeWork only has the fourth floor of 5049 Edwards Ranch Road, Fort Worth, TX 76109, and there are other companies in the building. Various sources give their move date to Fort Worth as December 2023, though they were sending out press releases datelined Fort Worth as early as June 2023. [CoinDesk]

Did Consensys move to Fort Worth specifically to try to win a bizarre ruling from O’Connor with this weird filing as their judicial lottery ticket? This is almost too crypto an idea to seriously posit, but it’s less nonsensical than any other interpretation we have. Ideas welcome!

Update 2: Nevermind! Consensys straight up admits they moved to Ft. Worth for the courts.

Laura Brookover, Consensys head of litigation, tells Unchained: “For us, we moved to Texas because it’s a wonderful laboratory for innovation. Texas celebrates individual freedom, celebrates technology, and it’s a great opportunity for us being headquartered here to call on the courts and to say, please help us, because what the SEC is doing is unlawful.” [Unchained]

MIT Tech Review: Ethereum moved to proof of stake. Why can’t Bitcoin? 

I just got a story published in MIT Technology Review on why Bitcoin will likely never move to proof of stake. [MIT Tech Review]

Since Ethereum migrated to proof of stake, that’s got more people asking, “Why is it necessary for Bitcoin to consume an entire country’s worth of energy?”

Bitcoin is decentralized in theory only and the folks who control the code are fiercely tied to keeping Bitcoin in its original form for completely irrational reasons.

Bitcoin Cash in 2017 was the last attempt to make any reasonable update to the Bitcoin reference code — and BCH ended up just another altcoin.

Bitcoin purists still refer to Bitcoin Cash as a “rebellion” and a “corporate takeover” as opposed to a sincere effort to reduce congestion on the network.

Now that lawmakers and regulators are getting more fed up with crypto, the pressure for Bitcoin to reduce its CO2 footprint will only increase.

My first story in MIT Tech Review with added ramblings on Web3 and Ethereum’s Beacon Chain

I just wrote my first story for MIT Tech Review. 

It is an explainer piece on Ethereum’s move to proof of stake. What follows are notes from the story — along with additional ramblings and quotes from your favorite crypto skeptics.

When NFTs became a big thing in 2021, that drew a lot of attention to Ethereum, where most NFTs are traded. It also brought a lot of attention to the environmental horrors of proof of work.

Bitcoin and Ethereum both rely on proof of work to add new blocks to the chain. Together, they consume as much electricity as the entire country of Italy, according to Digiconomist. 

Meanwhile, venture capitalists are shoveling cash at companies building Web3 — a supposedly new iteration of the internet where apps will run on permissionless blockchains, mainly Ethereum. 

The problem is that permissionless blockchains — those that are open to the public and depend on a cryptocurrency to incentivize miners and maintain their security — are incredibly inefficient. They are sluggish. They can’t handle much data, and they don’t scale.

Case in point: CryptoKitties slowed the entire Ethereum network to a crawl in 2017. 

In his article “The Web3 Fraud” Nicholas Weaver, a researcher at the International Computer Science Institute at Berkeley, explains that Web3 is “a technological edifice that is beyond useless as anyone who attempts to deploy a real application will quickly discover.”

Andreessen Horowitz (a16z), one of Silicon Valley’s top venture capital firms, is a big promoter of Web3. It has invested heavily in at least a dozen platforms that support NFTs alone, among them: Dapper Labs, OpenSea, Manifold, and soon, possibly, Bored Ape Yacht Club. Ethereum is crucial to a16z’s Web3 story.

Clearly, that story needs something more to support it. It needs a rocket-boosted ETH 2.0.

Scaling to the moon

In a proof of stake system, validators replace miners. Instead of investing in expensive ASIC systems that eventually end up in landfills, you invest in the native coins of the system.

Ethereum Foundation, the nonprofit behind Ethereum, says its proof of stake will consume 99.95% less electricity than proof of work. Ethereum currently handles roughly 15 transactions per second. Its founder Vitalik Buterin said ETH 2.0 could potentially handle a whopping 100,000 transactions per second. That would beat out Visa, which claims 65,000 transactions per second.

Ethereum was supposed to be a proof of stake blockchain from the start, according to its whitepaper. But in 2014, Buterin concluded that developing a proof of stake algorithm was non-trivial. So Ethereum settled for proof of work instead, while it went to work developing a proof of stake algorithm. Ethereum’s switch to proof of stake has been six months away for years. 

Now, supposedly, the big moment is soon to arrive.

Ethereum is currently testing a proof of stake blockchain called the Beacon Chain. This will be the heart of ETH 2.0. So far, 9.7 million ETH ($25 billion) is staked on the Beacon Chain. To become a validator, you have to lock up 32 ETH. If you don’t have that much ETH on hand, you can join a staking pool.

In an upcoming event called “The Merge,” which was supposed to happen in Q1 2022 but got pushed to to Q2 2022 in October, Ethereum will combine the Beacon Chain with the Ethereum Mainnet.  

After The Merge takes place, the next step is sharding — splitting the Ethereum chain up into 64 separate chains, so the network can scale. Sharding won’t happen until 2023. This is where the network reaches toward that theoretical number of 100,000 transactions per second.

Critics, however, doubt sharding will be any more efficient than a single chain. 

Jorge Stolfi, a computer science professor at the State University of Campinas in Brazil, told me: “Almost every transaction will require updating two shards in an ‘atomic’ way (either both are updated or neither is updated). That will be the job of the central (Beacon) chain. I doubt very much that they can do that more efficiently than the current single-chain scheme.”

Ethereum, a centralized system

Scaling isn’t the only issue at hand in Ethereum’s move to proof of stake.

Proof of work’s decentralization suffers from economies of scale. Large mining operations are better able to maximize profits while lowering costs. This resulted in five mining operations controlling more than half of Bitcoin’s hash rate in 2020.

Like proof of work, proof of stake will naturally tend toward centralization.

Those who have the deepest pockets and stake the most coins will have the best chances of “winning the lottery,” thus reaping newly minted coins in the form of the block reward.

The big staking validators are already getting themselves into position. US crypto exchanges Coinbase and Kraken hold 78,000 out of 296,000 validators on the Beacon Chain.

A16z is also getting in on the action. It invested $70 million into staking provider Lido and is using Lido to stake an undisclosed portion of its venture arm’s ETH holdings on the Beacon Chain.

Proof of work and proof of stake both aim to get rid of a central gatekeeper, but that comes at a huge cost. One wastes electricity; the other wastes coins, which get locked up and pulled out of circulation.

“Whatever Sybil defense they use, economics forces successful permissionless blockchains to centralize; there is no justification for wasting resources in a doomed attempt at decentralization,” David Rosenthal said in a recent blog post. Rosenthal is known for co-creating Stanford University’s LOCKSS technology for the distributed preservation of digital content. 

The one advantage of proof of stake that we can count on? At least it won’t destroy the planet.
