Definition ∞ Zero MEV describes a theoretical state where Maximal Extractable Value opportunities are eliminated or significantly reduced within a blockchain’s transaction ordering process. This condition aims to ensure that transaction ordering is fair and that validators or block builders cannot extract additional value beyond standard block rewards. It promotes a more equitable network environment.
Context ∞ Crypto news often reports on research and protocol developments striving for zero MEV, particularly in proof-of-stake systems. The pursuit of this state addresses concerns about front-running, sandwich attacks, and other forms of value extraction that can negatively impact users. Achieving zero MEV is a significant goal for enhancing network integrity and user experience.
