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, April 1 (UTC+8): Ethereum Foundation researcher Jihoon Song introduced the progress of FOCIL (Fork-Choice Enforced Inclusion Lists, i.e., EIP-7805) at EthCC[9]. He noted that currently over 80% of Ethereum blocks are produced by a small number of builders, and the resulting high centralization brings significant censorship risk. FOCIL aims to shift the transaction inclusion power from a single builder to a decentralized committee of validators. FOCIL’s core process consists of three steps: for each slot (Slot), 16 validators are randomly selected to form a committee. Members publish local inclusion lists based on their own observations of the mempool. After the proposer aggregates them, the validators vote to reject blocks that do not include transactions with valid inclusion lists. This means that resistance to censorship no longer depends on moral agreements, 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 upcoming major upgrades. 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)
