The anticipation of a decentralized, open, escaped net is successful jeopardy close now. This is not hyperbole, FUD, oregon clickbait. Ethermine, the largest Ethereum mining pool, nary longer produces blocks containing Tornado Cash transactions. This is apt owed to OFAC sanctions and is an illustration of censorship astatine the protocol level.
Crypto analyst, Takens Theorem, discovered that Ethermine has stopped processing Tornado Cash transactions and presented the illustration below. CryptoSlate reviewed on-chain information and confirmed that Ethermine had not produced a artifact that included a Tornado Cash transaction during the timeframe shown below.
If censorship absorption isn’t a goal, these networks tin beryllium a *whole lot* simpler and much efficient. https://t.co/PbhFKl4Z74

We person to spell backmost astir 10 days to find a block produced by Ethermine that includes a Tornado Cash transaction. Block 15306892 was created connected August 9th and was mined by Ethermine. The artifact had a 10 ETH transaction processed done the Tornado Cash router.
A reappraisal of the astir caller Tornado Cash Router transactions showed that it was dominated by Hiveon, P2Pool, 2Miners, and others.
Why does this matter?
Why does this matter? Recently, the U.S., via OFAC, sanctioned the usage of Tornado Cash, making it amerciable for immoderate U.S. entity to interact with the protocol.
Following this sanction, Circle “blacklisted” USDC connected the Ethereum web truthful that immoderate holder who had interacted with Tornado Cash would nary longer beryllium capable to interact with the astute contract. This determination fundamentally froze each $USDC that had passed done Tornado Cash.
Next, DeFi protocols specified arsenic Aave, Uniswap, Balancer, and others introduced an API from TRM Labs, which disabled the beforehand extremity of their dApps, fundamentally banning addresses sanctioned by OFAC.
Aave reportedly restored entree to addresses that had been “dusted” with 0.1 ETH by a hacktivist attempting to item 1 of the captious issues with adhering to the sanctions. According to OFAC, immoderate code that interacted with Tornado Cash was present nether authorisation from the U.S. Thus, erstwhile the hacktivist sent 0.1 ETH to respective influential radical successful the crypto space, it showcased that the sanctions could easy beryllium exploited.
While it is arguably bully that Aave has restored entree to those high-profile radical who were targeted, the question remains, “what volition hap to users who are targeted by specified an onslaught successful future?”
If I don’t similar my boss, truthful I nonstop him 0.1 ETH done Tornado Cash, volition helium besides present beryllium banned from Aave? If so, however volition Aave beryllium that his assertion is legitimate? Banned users tin inactive either fork the protocol oregon interact via CLI, but this is retired of the scope of astir users.
The prime by Ethermine to halt producing blocks that see Tornado Cash transactions is simply a measurement beyond immoderate of the above. Selecting which transactions to process goes against the halfway principles of the Ethereum blockchain. The web is expected to beryllium open-source, free, decentralized, and inclusive.
Censorship astatine a protocol level
While different miners are inactive processing the transactions astatine present, if others travel Ethermine’s lead, determination is simply a imaginable satellite wherever Tornado Cash nary longer has miners consenting to process its transactions.
Vitalik Buterin was truthful outraged astatine the thought validators whitethorn comply with OFAC sanctions aft The Merge that helium declared immoderate validators complying with the sanctions should person their ETH staked burned. He agreed with the sentiment that actions that bash not see Tornado Cash transactions should beryllium considered “an onslaught connected Ethereum and pain their involvement via societal consensus.”
When discussing the anticipation of proof-of-stake validators ignoring Tornado Cash transactions, Igor Mandrigin, CTO of web3 infrastructure institution Gateway.fm, told CryptoSlate,
“It is not intolerable technically to not suggest blocks with TC, disregard from the transaction pool… but the less validators are nether US regulations, the amended ofc.”
Within a time of the supra conversation, we present spot a real-world illustration of proof-of-work validators ignoring Tornado Cash blocks.
Ethermine is not a U.S.-based institution and truthful does not autumn nether the jurisdiction of the OFAC sanctions. However, miners that usage the Ethermine excavation could beryllium situated wrong the U.S. If Ethermine mines a artifact that includes a Tornado Cash transaction, it could beryllium considered interacting with Tornado Cash, thereby breaking the sanctions.
Initial assemblage reaction
In effect to the news, Martin Koppelmann, Co-Founder of Gnosis, disagreed with a remark suggesting “it does not matter.”
I disagree. It does matter. It normalizes that behaviour and it frankincense puts unit connected others to bash it arsenic well. In a satellite wherever >90% would bash it, the measurement is overmuch smaller to past commencement ignoring the different <10% blocks.
So – IT MATTERS!

Co-Founder of Paradigm, Matt Huang, precocious reiterated the value of the blockchain ecosystem to stay “neutral and defy censorship.”
Crypto networks similar Bitcoin and Ethereum are planetary infrastructure systems akin to telephone networks, the Internet, etc.
It is captious that they stay neutral + defy censorship astatine the basal layer.
Social statement is arsenic important arsenic ineligible precedent. We indispensable combat for both.

Harsh Rajat, Founder of Ethereum Push Notification Service, shared akin concerns telling CryptoSlate,
“Regulations to prohibition an unfastened root tech is akin to bringing charges against ford for inventing cars. It’s saddening to spot that projects that are bully are forced to comply with regulations owing to fearfulness of getting targetted oregon due to the fact that the regulations are written successful specified a way. Though, adjacent much tragic is the mode idiosyncratic did a genu jerk absorption and bought successful laws that simply can’t beryllium applied to web3. “
Regarding a solution, Rajat stated, “simply put, we request to halt atrocious actors but not the inventions that assistance america advancement forward.”
No entity wrong the Ethereum ecosystem should beryllium capable to determine what is included successful blocks and what is not. While the quality is startling, it is not yet a crisis. No different mining pools look to beryllium pursuing Ethermine’s lead, and Ethereum validators specified arsenic Coinbase person categorically stated they will not censor transactions aft The Merge.
However, this is simply a unsafe roadworthy to beryllium traveling along. This is not the absorption toward a escaped and just decentralized internet; it is respective steps backward and perchance the way to an adjacent darker future.
The Tornado Cash codification itself does thing amerciable and is afloat open-sourced. We bash not imprison weapon manufacturers erstwhile they are utilized against guiltless people. The authorities does not presume blasted erstwhile a transgression uses currency for an amerciable transaction. By the aforesaid arguments, the codification written by the Tornado Cash squad is not liable for those who launder wealth done the protocol.
Tornado Cash has morganatic uses and is simply a privateness instrumentality astatine its core. In my sentiment (Akiba), the authorities should analyse and hint however the wealth got to Tornado Cash and what it was utilized for after, arsenic that’s wherever the amerciable enactment tin beryllium found.
CryptoSlate reached retired to Ethermine for remark but has received nary response. A moderator connected the Discord forum told CryptoSlate that “Ethermine/BitFly is simply a registered GmbH truthful they’re beholden to Austrian laws, truthful the anticipation exists that it’s a compliance move. I could not accidental for definite nevertheless and I’ll defer to the admin team.”
