State Root Verification

Definition

State root verification is a cryptographic process used in blockchain systems to confirm the integrity and accuracy of the entire network state at a given block height. The state root, typically a Merkle root, cryptographically summarizes all accounts, balances, and smart contract data. By verifying this single hash, a node can confirm that its local state matches the global, agreed-upon state without needing to process every transaction individually. This method is fundamental for light clients and efficient synchronization.
