Distributed State Machine Replication

Definition ∞ Distributed State Machine Replication is a method for building fault-tolerant systems by replicating the same deterministic state machine across multiple nodes. Each node processes the same sequence of client requests, maintaining identical states. This approach ensures system consistency and availability even if some nodes fail. It is a foundational concept for many blockchain and distributed ledger technologies.
Context ∞ In blockchain technology, distributed state machine replication forms the bedrock of consensus mechanisms, guaranteeing data integrity and network resilience. Ongoing research aims to optimize its performance, particularly in terms of latency and throughput, while preserving its robust fault tolerance properties. Future advancements will likely influence the scalability and responsiveness of decentralized applications.
