Vitalik: If we try to ban transactions with gas fees higher than 50, a large number of junk chains will appear

Max Resnick, the research director of SMG, posted on social media that MEV is fundamentally about control. The proposer can control which transactions are included in the block and in what order they are included. In other words, MEV is about censorship and reordering. The good news is that this problem can be solved. The first step is to address censorship resistance by setting up multiple parallel proposers. The second step is to solve the reordering problem. Once there is a multi-proposer architecture, proposers can reach consensus on a set of unordered transactions, and the execution layer is responsible for sorting them using deterministic rules.

In response to this, Vitalik Buterin, co-founder of Ethereum, replied that wouldn't this lead to people flooding the chain with a large number of transactions to collect MEV and maximize their chances of being the first? Therefore, you will still get "MEV auctions," but it will bring more negative externalities to the protocol.

We saw this situation during the ICO era in 2017 when some projects tried to prohibit transactions with gas fees higher than 50, resulting in a large number of junk chains.
