SMR Fairness

Definition ∞ SMR fairness refers to ensuring equitable access and processing of transactions within a state machine replication system. This concept addresses the challenge of preventing block producers or validators from unfairly prioritizing or reordering transactions to gain an advantage, often referred to as miner extractable value (MEV). Achieving SMR fairness means that all valid transactions are processed in a transparent and unbiased manner, preserving the integrity and predictability of the system’s state transitions. It is a critical consideration for decentralized networks aiming for true impartiality and resistance to manipulation.
Context ∞ SMR fairness is a topic of advanced research and development in the blockchain community, particularly concerning high-throughput decentralized ledgers. News discussions often revolve around new consensus algorithms or protocol designs that aim to minimize MEV and enhance transaction ordering fairness. The pursuit of SMR fairness is vital for building more robust and equitable decentralized financial systems, ensuring that all participants operate under consistent and predictable rules.
