A Distributed State Machine is a system where multiple nodes work together to achieve consensus on the state of the system. Each node maintains a copy of the state and processes transactions independently. This ensures that all nodes remain in sync without a central authority.In this model, every transaction is treated as a state change, and nodes follow a predefined protocol to agree on the order of these changes. By reaching consensus, the system prevents issues like double-spending and maintains a reliable record of all transactions.The distributed nature enhances security and resilience against failures, as there’s no single point of failure. Instead of relying on a centralized server, each participant contributes to the integrity of the network.This approach is foundational for many blockchain systems, enabling decentralized applications and smart contracts to function reliably and transparently. It allows for trustless interactions among participants without needing to rely on intermediaries.
