State Machine

A state machine is a model that describes the behavior of a system by defining its possible states and the transitions between them. In the context of a blockchain, the ledger is a global state machine that is updated by transactions.

Every node in the network maintains a copy of this state, ensuring that everyone agrees on the current balances and contract data. Smart contracts are themselves small state machines, with internal variables that change based on user interaction.

Understanding the state machine model is fundamental to grasping how blockchains achieve consensus and maintain integrity. It provides the framework for analyzing how protocols evolve over time and how they respond to different inputs.

For developers, designing efficient state transitions is key to creating scalable and secure decentralized applications. It is the underlying architecture of all programmable money.
