Ethereum Foundation researcher: FOCIL is confirmed to be included in a future major upgrade, directly encoding censorship resistance into the consensus layer.

According to Foresight News , Ethereum Foundation researcher Jihoon Song presented the progress of FOCIL (Fork-Choice Enforced Inclusion Lists, also known as EIP-7805) at the EthCC[9] conference. He pointed out that currently more than 80% of Ethereum blocks are produced by a small number of builders, and this high degree of centralization brings significant censorship risks. FOCIL aims to transfer the right to include transactions from a single builder to a decentralized validator committee. FOCIL's core process consists of three steps: Each slot randomly selects 16 validators to form a committee. Members publish local containment lists based on their observations of the mempool. After the proposer aggregates these lists, validators refuse to vote for blocks that do not contain transactions from valid containment lists. This means that censorship resistance no longer relies on moral agreements but is directly encoded into the fork rules. Compared to previous schemes, the committee mechanism significantly reduces the risk of bribery and ransomware attacks and provides native support for account abstraction (AA) and privacy protocols. Jihoon revealed that FOCIL has been identified as a core feature of future major Ethereum upgrades. Most clients have already completed prototype implementations, and the community is optimizing proof size and gas efficiency to support future "GigaGas" level scalability.
