Coinbase would rather shut down staking than enable on-chain censorship

With a ban on Tornado Cash, many DeFi proponents were worried that crypto exchanges, which are also key validators of Ethereum, would succumb to pressure and impose protocol-level censorship.

In light of the recent ban on crypto mixing tool Tornado Cash and the subsequent arrest of the Tornado Cash developer, there has been a growing debate around what crypto services providers would choose between decentralization and censorship in form of compliance.

The question has become more prominent as Ethereum (ETH) is moving from its current proof-of-work (PoW) blockchain to a proof-of-stake (PoS) mining consensus. With the transition less than a month away, a user pointed out that more than 66% of validators on the Beacon chain (Ethereum PoS chain) will adhere to the United States Department of the Treasury’s Office of Foreign Assets Control (OFAC) regulations.

Start with the big, current one.

When asked whether Coinbase and others would choose to adhere to compliance requests and impose protocol-level censorship or shut down staking services, Brain Armstrong, the CEO of Coinbase, chose the latter. Armstrong said:

“It’s a hypothetical we hopefully won’t face. But if we did we’d go with B I think. Got to focus on the bigger picture. There may be some better option (C) or a legal challenge as well that could help reach a better outcome.”

There was growing speculation about the actions of Coinbase, Kraken, and other prominent crypto exchanges who are also key ETH validators on the Beacon chain.

Many believed that centralized crypto exchange would take the easy way out and impose protocol-level censorship rather than block individual transactions from banned crypto mixers such as Tornado Cash.

U.S. validators (which includes very powerful Coinbase) are gonna push for protocol-level censorship

They can’t self-help by merely avoiding facilitation of blocks containing U.S.-sanctioned txs, because under certain conditions they might be dramatically slashed from doing so.

The current dilemma comes from the OFAC sanctions that deemed all tornado cash transactions illegal. However, decentralized finance (DeFi) experts believe it has complicated the issue. Instead of sanctioning a particular address or the country, the regulators have decided to ban the protocol.

Here’s the list of Tornado Cash resources that were banned

– Tornado Cash @GitHub organization
– personal @GitHub accounts of TC contributors
– all $USDC on Tornado Cash contracts @circlepay
– @infura_io RPC
– @AlchemyPlatform RPC

Experts believe the decision of a ban would discourage many protocols and exchange operators from engaging with anything related to Tornado Cash, including ETH transacted through the mixer which could lead to unnecessary censorship.
