Ethereum Foundation Researcher: FOCIL has been confirmed to be included in future major upgrades, directly encoding censorship resistance into the consensus layer.

ME News update: On April 1 (UTC+8), Ethereum Foundation researcher Jihoon Song presented the progress of FOCIL (Fork-Choice Enforced Inclusion Lists, i.e., EIP-7805) at the EthCC[9] conference. He noted that currently, more than 80% of Ethereum blocks are produced by a small number of builders, and the high degree of centralization brings significant censorship risks. FOCIL aims to transfer transaction inclusion rights from a single builder to a decentralized committee of validators. FOCIL’s core process is divided into three steps: for each slot, a committee of 16 validators is randomly selected. Members publish local inclusion lists based on their observations of the mempool. After the proposer aggregates them, validators will vote to reject blocks that do not include transactions with valid lists. This means that resistance to censorship no longer relies on moral agreements, but is directly encoded into the fork rules. Compared with the previous proposal, the committee mechanism significantly reduces the risk of bribery and extortion attacks, and it provides native support for account abstraction (AA) and privacy protocols. Jihoon revealed that FOCIL has been identified as a core feature of Ethereum’s subsequent major upgrade, and that most clients have completed prototype implementations. The community is optimizing proof size and Gas efficiency to support future scalability at the “GigaGas” level. (Source: Foresight News)
