Definition ∞ An SMR Synchronizer, within the context of State Machine Replication, is a component or algorithm responsible for coordinating the state updates across multiple replicas to ensure they remain consistent. It manages the ordering and delivery of operations to each replica, maintaining a unified system state despite potential network delays or failures. This synchronizer is vital for achieving strong consistency guarantees.
Context ∞ In distributed ledger technologies and blockchain systems, SMR Synchronizers are conceptual components within the broader consensus mechanism that ensure all participating nodes process transactions in the same order and arrive at the same ledger state. News regarding advancements in blockchain scalability or finality often implicitly touches upon improved synchronization techniques. The reliability of these synchronizers directly impacts the integrity and agreement across a decentralized network.
