MEV-Burn
A proposed Ethereum mechanism that redirects the MEV a block captures away from the proposer and burns it, spreading the value across all ETH holders instead.
MEV-Burn is a design that builds on enshrined proposer-builder separation. Instead of letting the block proposer keep the full bid paid by builders, attesting validators observe the highest bid circulating shortly before a slot and enforce a floor: the proposer must burn that amount, and may only pocket whatever value arrives above it in the final moments.
The goal is to stop MEV from accruing to a lucky few proposers, which worsens staking centralization and reward variance. By burning the base portion — much like the EIP-1559 base fee — the value is returned to every ETH holder through reduced issuance. The idea remains a research proposal rather than a shipped feature, and depends on in-protocol PBS to be deployed safely.
