Ethereum developers have scheduled the FOCIL mechanism (EIP-8081) for the upcoming Hegota upgrade, making transaction inclusion a protocol-level rule rather than a builder's choice. Under FOCIL, 16 validators per block publish lists of pending transactions, and any valid listed transaction must be included if there is room, requiring all 16 validators plus the builder to collude for censorship. The change aims to strengthen Ethereum's censorship resistance while preserving the efficiency of specialized block building.
