Odaily Planet Daily News Vitalik Buterin said that centralized sequencers actually have many advantages:
*Centralized sequencers can ensure that they will not steal users' money by frontrunning and other methods;
*Instant preconfirmations;
*It is easy to turn a traditional application into a blockchain application because the server directly becomes a sequencer.
The decentralized characteristics of blockchain can be used to avoid the risks of centralized sequencers: the forced inclusion mechanism does not allow the sequencer to censor users, and the optimistic or zk proof mechanism does not allow the sequencer to change or violate the rules of the application (for example, suddenly inflate a token or nft collection).
However, centralized sequencers still have risks, so we cannot rely entirely on centralized sequencers to solve the problem. It is also important to have the ability to trade based on rollup or directly on L1. So I support the two-part ecosystem to promote these two methods at the same time, and then we can see which method is more suitable for which application.
Maintaining the ability of ordinary users to issue censorship resistant transactions is of course critical.
