Definition ∞ SMR Fairness Link refers to a mechanism or property within a State Machine Replication (SMR) system that ensures equitable access and processing for all submitted operations or transactions. It aims to prevent any single validator or malicious actor from unfairly prioritizing, delaying, or censoring specific requests. This link guarantees that the order of operations reflects a fair sequence, often based on submission time or other neutral criteria. It is vital for the integrity and trustworthiness of distributed ledgers.
Context ∞ The SMR Fairness Link is a critical area of focus in advanced blockchain research, particularly in addressing challenges like miner extractable value (MEV) and front-running. Innovations in this domain seek to enhance the fairness of transaction ordering and improve the overall security and decentralization of state machine replication protocols. Discussions around this concept are central to ensuring equitable participation in future decentralized systems.
