According to Wu, SMG research director Max Resnick recently proposed a new solution to the MEV and anti-censorship problems: Braid, which implements multiple parallel block proposers.
The basic idea is to use the same validator set to run several parallel consensus chains separately. All chains are synchronized, and the final proposed block is a collection of block transactions proposed by each sub-consensus chain.
Max Resnick believes that many current solutions such as FOCIL, Inclusion Lists, PEPC, and Vote Extensions, etc., are to maintain anti-censorship properties by adding patch tools, which are essentially only temporary solutions and not fundamental solutions.
It is worth noting that Vitalik had previously questioned this idea, believing that this would cause users to continuously initiate transactions in order to get a higher transaction ranking, ultimately leading to on-chain congestion and MEV auctions with negative externalities.
