FOCIL will strengthen Ethereum's censorship resistance by allowing validator committees to require certain transactions in blocks, reducing builder power to exclude valid transactions.

"FOCIL addresses censorship resistance instead. It would allow committees of validators to require certain transactions in blocks, reducing specialized builders' ability to exclude valid transactions. The group strongly supports FOCIL and Frame Transactions. It described censorship resistance, or 'openness,' as one of Ethereum's core value propositions."

"FOCIL uses validator-created inclusion lists to make it harder for specialized block builders to omit valid transactions. Ethlabs strongly supports the feature, which has already secured the headliner position."
