Breaking down Ethereum’s evolution and its impact on crypto markets

Welcome to Valid Points. In today's issue, Margaux Nijkerk writes about the dramatic reversal of censorship on Ethereum, as fewer than 1/3rd of new blocks over the past 5 days are OFAC-compliant. 

Ethereum’s “censorship” problem seems to have changed course over the past six months. After the U.S. government sanctioned Tornado Cash transactions to its citizens in August, the vast majority of blocks added to the blockchain were OFAC-compliant.

Now, the share of “censored” blocks has shrunk to less than a third – in what might be seen as a comeback for Ethereum’s anti-censorship ethos. 

According to the site MEV Watch, during the past weekend and into the beginning of this week, roughly one in three blocks that made it onto the Ethereum blockchain was OFAC-compliant. This means that about 30% of blocks excluded transactions sanctioned by the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC), including Tornado Cash. 

Flipping that around, more than two-thirds of blocks that made it onto the Ethereum blockchain over the last 24 hours are non-OFAC compliant.

Just a month ago, Ethereum validators were still censoring about 50% of blocks that made it onto the blockchain. The last time that Ethereum had such low levels of censorship was September 24, 2022. 

What contributed to the reversal? 

Since Ethereum went through the Merge in September, about 85% of the blocks that made it onto the blockchain participated in a middleware known as MEV-Boost, where validators can request pre-made blocks from builders.

MEV-Boost is a software that helps validators earn MEV, or maximal extractible value, which are profits that come from rearranging or including certain transactions within a block. The MEV-Boost software was innovated by Ethereum research and development team Flashbots in order to distribute MEV among validators more equally.

While MEV-Boost hasn’t been integrated into Ethereum at the protocol level, it’s widely used by the Ethereum ecosystem, as 85% of validators have relayed blocks via the middleware component. Flashbots also has its own relayer for validators to connect with, used by roughly 25% of validators.

After OFAC sanctioned Tornado Cash, there was debate over whether validators should include those transactions or not. Ever since then, the Ethereum community has continued to push for a censorship reversal, and the results of those efforts now appear to be paying off thanks, in large part, to the introduction of new, non-censoring relays. 

At the time the sanctions went into effect, most validators were connected to Flashbots’ MEV-Boost relay which Flashbots immediately programmed to censor transactions by default.

In response to community backlash, however, Flashbots raced to complete the process of open-sourcing its code for MEV-Boost, so others could develop their own non-censoring relays. 

In November, Agnostic and ultra sound relays with a non-censoring version of MEV-Boost were introduced. Since then, they have risen up in the ranks of relays delivering blocks on Ethereum. Flashbots accounts for delivering about 26% of the blocks over the past 14 days, while Agnostic and ultra sound each have delivered roughly 20% of the blocks over the past 14 days. 

Over the weekend, Agnostic and ultra sound each delivered more blocks on Ethereum than Flashbots did.

Martin Köppelmann, co-founder of Gnosis Chain, which runs the Agnostic relay, told CoinDesk that “it took some time to get the word out and demonstrate that we offer a reliable relay.” 

Now that validators have had the opportunity to experiment with MEV-Boost, many have started to turn to alternative relays like Agnostic and ultra sound. 

“The number of validators that are connected to us is constantly growing,” Köppelmann said. “We were already able to deliver the most blocks of all relays for some period of time.”

Validated Takes

Arbitrum will airdrop a token and transition to a DAO.

• WHY IT MATTERS: The leading Ethereum layer 2 network will airdrop its long-awaited ARB token to community members on Thursday. ARB will mark Arbitrum’s official transition into a decentralized autonomous organization (DAO), meaning ARB holders will be able to vote on key decisions governing Arbitrum networks, which allow users to transact on the Ethereum blockchain with greater speeds and lower fees.

Ethereum’s Shanghai hard fork is set to occur on April 12.

• WHY IT MATTERS: Ethereum developers set a target date of April 12 for its long-awaited Shanghai hard fork, which marks the completion of Ethereum’s full transition to a proof-of-stake (PoS) network, and will enable staked ETH withdrawals. Since the Merge, Ethereum developers have run numerous tests in order to ensure that staked ETH withdrawals would function properly, and all three tests on Ethereum’s testnets ran smoothly.

Polygon has partnered with Salesforce for an NFT-based loyalty program. 

• WHY IT MATTERS: Ryan Wyatt, president at Polygon Labs, tweeted, “Salesforce will help their clients onboard to Polygon with its management platform to help its clients create token-based loyalty programs.” The news comes after the customer relationship management software giant said on March 15 that it is expanding its client services to include management of NFT loyalty programs.Read more here.
