Definition ∞ The MSIS problem, or Miner Extractable Value (MEV) Searcher Incentive Skew problem, refers to a specific economic inefficiency within blockchain transaction ordering. It describes how the current incentive structures disproportionately reward MEV searchers at the expense of other network participants. This skew can lead to suboptimal outcomes for users and potential network centralization. Addressing it aims to improve market fairness.
Context ∞ The MSIS problem is a technical and economic concern often discussed in advanced blockchain and decentralized finance (DeFi) news. Current debates focus on protocol adjustments and new transaction ordering mechanisms designed to mitigate its impact. Solutions seek to rebalance incentives and promote a more equitable distribution of MEV.
