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), Jihoon Song, a research fellow at the Ethereum Foundation, introduced the progress of FOCIL (Fork-Choice Enforced Inclusion Lists, i.e., EIP-7805) at EthCC[9]. 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 risk, while FOCIL aims to move transaction inclusion rights from a single builder to a decentralized committee of validators. FOCIL’s core process consists of three steps: for each Slot, 16 validators are randomly selected to form a committee; members publish local inclusion lists based on their observations of the mempool; after the proposer aggregates them, validators will vote to reject blocks containing transactions that do not have valid lists included. This means that resistance to censorship no longer depends on moral commitments, but is directly encoded into the fork-choice rules. Compared with earlier proposals, the committee mechanism significantly reduces the risk of bribery and extortion attacks, and provides native support for account abstraction (AA) and privacy protocols. Jihoon revealed that FOCIL has been identified as a core feature for Ethereum’s subsequent major upgrade, and that most clients have already completed prototype implementations; the community is optimizing proof size and Gas efficiency to support future “GigaGas”-level scalability.
