An increasing number of nodes in the network of the second largest cryptocurrency by capitalization are starting to use American bots, which increase censorship in the blockchain
About 45% of the blocks on the Ethereum network are verified by US sanctions-compliant robots, Lahan Feeney, CEO of block chain company Labrys, says Cointelegraph. According to him, the reports, which indicate that there are only 25% of such blocks, are already outdated and, at the moment, probably every second block is subject to censorship.
Feeney explained that an increasing number of ETH validators are starting to use centralized MEV-boost relay flashbots, which are most often located in the US and “censor certain transactions in the blocks they create, especially Tornado Cash transactions”.
MEV bots are centralized software designed to extract maximum extractable value (MEV). Such programs have become popular among validators because they efficiently select transactions that can generate the most revenue.
On September 28, Labrys released the MEV Watch tool, which shows which bots adhere to US Office of Foreign Assets Control (OFAC) sanctions. According to Feeney, under severe censorship, bots “reject” blocks with transactions associated with sanctioned addresses, making it impossible to capture those transactions in the block chainregardless of the amount of commission awarded.
These results are supported by a study published on September 28, which indicates that out of more than 19,000 blocks verified using Mev-Boost Relay bots, none included a Tornado cash transaction.
At the same time, the United States Securities and Exchange Commission (SEC) complaints that transactions on the Ethereum Network are made in the USA, since block chain validators are clustered more densely in the United States than in any other country.
