Distributed State Machine

Definition ∞ A distributed state machine is a system where the state is replicated across multiple network nodes, and all nodes process transactions in the same order to maintain a consistent state. Each node independently computes the next state based on a sequence of inputs. This architecture provides high availability and fault tolerance. Blockchains function as a form of distributed state machine.
Context ∞ The concept of a distributed state machine is fundamental to understanding how blockchain networks maintain a consistent ledger of transactions. Discussions often relate to consensus algorithms that ensure all nodes agree on the order of operations and the current state of the system. Future developments focus on improving the performance and scalability of these state machines, allowing for higher transaction throughput and lower latency.
