Ethereum’s “audit” problem has grown over the past few months, with some validators tasked with maintaining the blockchain’s ledger ignoring certain transactions that did not comply with regulations. But crypto’s anti-censorship purists may have reason to be optimistic.
In the last 24 hours, 66% The blocks that made it onto the Ethereum blockchain were OFAC-compliant, meaning they excluded transactions involving parties approved by the U.S. Treasury Department’s Office of Foreign Assets Control.

Traditional companies generally comply with government sanctions, but in the idealized world of crypto what some call compliance others call censorship. As more Ethereum moderators choose to comply with OFAC, it will take longer for sanctioned transactions to arrive on Ethereum’s chain, and ideological purists argue that the network has begun to shrink from its founding commitments to financial independence and neutrality.
But the tide may be turning, with the number of audited blocks on Ethereum seeing a steady decline between mid-November and mid-December. According to mevwatch.info, a monitoring platform for tracking Ethereum “censorship,” saw the largest number of censored blocks on Nov. 21, with 79% of blocks issued on Ethereum coming from parties that have avoided OFAC-sanctioned transactions. Since then, the lowest day was December 9, when the censored blocks stood at 64%. Censorship is between 68% and 72% on most days.
So what accounts for the steady decline in OFAC-compliant volumes? Aside from the community backlash against censorship, there are now OFAC-agnostic ways to use MEV-Boost – a third-party software that pre-populates blocks for Ethereum moderators.
What’s wrong with MEV-Boost?
Always Since Ethereum merged As of September, most blocks that make it onto the blockchain go through a middleware component called MEV-Boost, a piece of software that allows validators — those who propose and approve “blocks” of transactions to Ethereum’s ledger — to send blocks from a network of builders to a pre-prepared request.
MEV-Boost was originally developed to help evaluators extract MEV, or Maximum extractable value – Additional profits that block builders and validators can gain by strategically reordering or adding transactions within a block.
The software, developed by Flashbots, an Ethereum research and development company, was born out of the company’s efforts to solve some of the problems created by MEV. Centralization And Censorship. This makes it possible for any Ethereum validator, large or small, to easily bite off a portion of the MEV pie.
To a large extent, it has succeeded in its aim. Without MEV-Boost, MEV might have been accessible only to the most sophisticated appraisers, and the software is used today. 91% of Ethereum’s moderators.
But problems arose with the MEV-Boost OFAC Approved Ethereum Mixer Project Tornado Cash In the month of August.
Many blockchain developers were angered by Tornado Cash’s approval. Writing code is seen by them as a form of free speech, and they see banning smart contracts as a form of censorship. But not all businesses and individuals operating Ethereum’s infrastructure (eg, its verifiers) are eager to test OFAC’s enforcement determination.
Validators using MEV-Boost must select a third-party “relayer” to deliver pre-built modules. Some of these relayers automatically filter out blocks containing Tornado transactions due to OFAC’s sensitivity. These “checked” relays include FlashBots’ own relay, which most users of the MEV-Boost platform use by default.
As a result of the proliferation of OFAC-compliant relays, Tornado cash transactions took longer than usual to complete on Ethereum, as they had to find other ways to get those transactions added to the blockchain.

If enough moderators (or relays) refuse to process OFAC-sanctioned transactions, those transactions may eventually be audited off-chain entirely.
In the weeks since this happened, what has the community done to reverse Ethereum’s audit trail?
New players in the game
Efforts to push for relay diversity have intensified. On October 14, 81% of blocks were relayed with MEV-Boost, Flashbots did so via relay. today, That figure stands at 74%.
from Last time I wrote about MEV-Boost, four new unaudited relays have entered the market. Those relays are Agnostic, Relayure, Ultrasound and Astes.
Although they currently make up a small fraction of relayed blocks, there is now a greater diversity of validators to connect to (six out of 10 relays available now are non-auditing).
We are proud to announce two new relays, Gnosis and @ultrasoundmoney communities.

Introduced by Agnostic Relay Team Behind the chain of Gnosis. Its co-founder, Stephen George, told CoinDesk: “We see a significant value added to Ethereum as a credible neutral platform. This is at risk if most moderators comply with audit requirements in a particular jurisdiction.
George added: “The argument was made even in a situation where 90% would be. [of blocks] Censored, it is still anti-censorship because you have to wait a long time for your block to be mined, but we saw this as a weak argument as neutrality is lost and some transactions are favored over others. That’s why we criticized the direction and started offering this relay as a constructive step to improve the network.

Others attribute the decline in audits to validators becoming more comfortable with the MEV-boost space and more willing to connect to relays that aren’t flashbots.
Uri Klarman, CEO of bloXroute, which operates three relays, two of which are uncensored, told CoinDesk, “The main reason we’re seeing the audit percentage drop is because more moderators are connecting to bloXroute’s relays, which now offer 20%. up to 25% of the volumes.”
George of Gnosis Chain also believes, “Most validators used the FlashBot relay mostly for convenience, but not because they needed OFAC compliance. That’s why it was an operational issue for them to switch once an alternative became available. George added, “Public sentiment definitely helped make this transition faster.”
