MEV Censorship Risks

MEV censorship risks arise when validators or searchers manipulate the ordering of transactions within a block to exclude specific users or protocols. Maximal Extractable Value (MEV) is the profit validators can make by reordering, inserting, or censoring transactions.

If a validator has the power to censor, they can prioritize their own profitable transactions while delaying or blocking others. This compromises the fairness and efficiency of the decentralized exchange and lending markets.

Censorship resistance is the primary defense against these practices, ensuring that the network remains neutral and open. However, as MEV strategies become more sophisticated, the pressure to censor for profit increases.

Addressing these risks requires the development of decentralized relayers and protocols that prevent validators from observing the contents of the mempool before block finalization.
