According to ChainCatcher, Max Resnick, director of research at SMG, posted on a social platform: “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 about review 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 consensus on a set of unordered transactions, and the execution layer is responsible for ordering them using deterministic rules. "
In response, Vitalik Buterin said: “Wouldn’t this lead to people collecting MEV by flooding the chain with transactions to maximize their chances of being first? So you still get the ‘MEV auction’ but with more negative externalities on the protocol.
We saw this during the ICO era in 2017 when some projects tried to ban transactions with gas fees above 50, and we received a lot of on-chain spam as a result.”
