State Transition Validation
State Transition Validation is the process by which a blockchain or smart contract ensures that any change to its ledger is valid according to its predefined rules. Every transaction must pass a series of checks before it is permanently recorded.
These checks verify signatures, account balances, and adherence to protocol invariants. If a transition would lead to an invalid state, such as a negative balance or a violation of protocol constraints, the entire transaction is rejected.
This process is essential for maintaining the security and consistency of a distributed ledger. It ensures that all participants agree on the current state of the system without requiring a central authority.
It is the core mechanism that prevents double-spending and unauthorized asset transfers.
