Vitalik: Setting up multiple MEV proposers may lead to chain spam problems and bring more negative externalities

Odaily News Max Resnick, head of research at SMG, wrote on X: MEV is fundamentally about control. Proposers can control which transactions are included in the block and in what order they are included. In other words, MEV is censorship and reordering. The good news is that it is possible to solve this problem. The first step is to solve censorship resistance and set up multiple parallel proposers; the second step is to solve the reordering problem. Once there is a multi-proposer architecture, the proposers can reach a consensus on a set of disordered transactions, and the execution layer is responsible for sorting them using deterministic rules. In response, Vitalik Buterin said: Wouldnt this lead to people collecting MEVs by flooding the chain with transactions, thereby maximizing the chance of being the first? So you still get the MEV auction, but there are more negative externalities on the protocol. We saw this in the ICO era in 2017, when some projects tried to ban transactions with Gas fees higher than 50, and as a result we received a lot of on-chain spam.
