Proof-of-Stake MEV

Mechanism

Proof-of-Stake (PoS) Miner Extractable Value (MEV) refers to the profit validators can make by arbitrarily including, excluding, or reordering transactions within the blocks they propose. This mechanism is an inherent aspect of blockchain transaction ordering, regardless of the consensus algorithm. In PoS, validators, rather than miners, have this power. The design of transaction ordering in PoS can significantly impact the distribution of these profits. This represents a subtle but significant economic force.
