On-Chain Data Integrity

Definition

On-chain data integrity refers to the accuracy, consistency, and immutability of information stored directly on a blockchain. This property ensures that once data is recorded on the distributed ledger, it cannot be altered or removed, providing a verifiable and tamper-proof record. Cryptographic hashing and consensus mechanisms collectively maintain this integrity across all network nodes. It is a foundational characteristic that underpins the trustworthiness and reliability of blockchain transactions and smart contracts.
