Multiple Proposer Transaction Fee Mechanism Design: Robust Incentives against Censorship and Bribery

Censorship resistance is one of the core value proposition of blockchains. A recurring design pattern aimed at providing censorship resistance is enabling multiple proposers to contribute inputs into block construction. Notably, Fork-Choice Enforced Inclusion Lists FOCIL is proposed to be include...
