State machine replication is a technique used in distributed systems to ensure that a group of nodes (or servers) maintain a consistent state, despite failures or network partitions. The concept is based on the idea that each node in the system can be thought of as a state machine, which operates under a defined set of rules and transitions from one state to another based on inputs (or commands).
