Definition ∞ State validity refers to the condition where the current state of a blockchain network accurately reflects all past, legitimate transactions. This means that every transaction recorded on the ledger adheres to the protocol’s rules, and the resulting changes to account balances, smart contract states, and other network parameters are correct. Maintaining state validity is fundamental to the integrity and trustworthiness of any blockchain, as it ensures that all participants agree on the accurate historical record and current status of the system. Cryptographic proofs and consensus mechanisms are designed to uphold this property.
