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

ME News announcement, 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 block builders, and the high centralization brings significant censorship risks. FOCIL is designed to transfer transaction inclusion rights from a single builder to a decentralized validator committee. FOCIL’s core process is divided into three steps: for each slot, 16 validators are selected at random to form a committee. Members publish local inclusion lists based on their observations of the mempool. After the proposer aggregates them, validators vote to reject blocks that do not include valid-list transactions. This means that anti-censorship is no longer dependent on moral agreements, but is directly encoded into the fork 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 confirmed as a core feature of Ethereum’s next major upgrade. Most clients have completed prototype implementations, and the community is optimizing proof size and Gas efficiency to support future “GigaGas”-level scalability. (Source: Foresight News)
