MEV Mitigation

Definition ∞ MEV mitigation refers to strategies and techniques designed to reduce or neutralize the impact of Miner Extractable Value (MEV). MEV represents the profit that block producers can extract from reordering, inserting, or censoring transactions within blocks. Mitigation aims to ensure fairer transaction ordering and prevent exploitation.
Context ∞ The ongoing development of MEV mitigation strategies is a critical area of research and development within the blockchain space, particularly for high-throughput networks like Ethereum. Current discussions focus on proposer-builder separation (PBS), encrypted mempools, and sophisticated transaction ordering algorithms. A central challenge is balancing the prevention of MEV extraction with the need for efficient block production and network security.
