SMG research director proposed a new solution to MEV & anti-censorship issues: Braid

Wu learned that Max Resnick, the research director of SMG, recently proposed a new solution to MEV & anti-censorship issues: Braid, which implements multiple parallel block proposers. The basic idea is to run several parallel consensus chains separately with the same set of validators. All chains are synchronous, and the final proposed blocks consist of transactions proposed by each sub-consensus chain. After consensus fusion, execution/state transitions follow agreed rules (such as priority fee decrement, etc.). Max Resnick believes that many existing solutions in this field, such as FOCIL (Fork-Choice enforced Inclusion Lists), Inclusion Lists, PEPC (Protocol Enforced Proposer Commitments), and Vote Extensions, are essentially patch tools to maintain anti-censorship properties, which are just treating the symptoms rather than the root cause. It is worth noting that Vitalik previously questioned this approach, suggesting that it may lead users to continuously initiate transactions to have them prioritized, ultimately causing on-chain congestion and further exacerbating the negative externalities of MEV auctions.
