Definition ∞ MEV-free Execution refers to the processing of blockchain transactions in a manner that prevents or significantly reduces the extraction of Miner Extractable Value by block producers. This execution environment aims to ensure that users’ transactions are ordered and included in blocks without predatory front-running, sandwich attacks, or other forms of value extraction. It promotes fairness and predictability for network participants. Achieving this state enhances transaction integrity.
Context ∞ The pursuit of MEV-free Execution is a critical area of research and development within the blockchain space, particularly following the transition to proof-of-stake. Debates revolve around various technical solutions, such as encrypted mempools and threshold encryption, designed to obscure transaction order from block builders. Future innovations seek to implement robust protocols that can effectively neutralize MEV, leading to a more equitable and efficient transaction environment for all users.
