Data Integrity

Definition ∞ Data integrity signifies the assurance that digital information remains complete, accurate, and unaltered throughout its lifecycle. In blockchain systems, this is achieved through cryptographic hashing and distributed consensus mechanisms. It ensures that recorded data is trustworthy and has not been subject to unauthorized modification.
Context ∞ The concept of data integrity is fundamental to the trustworthiness of blockchain records and digital assets. News reports often reference the immutability of blockchain data as a key feature ensuring the accuracy of transaction histories and ownership records. Current discussions revolve around the security of data storage, the potential for smart contract vulnerabilities that could affect data integrity, and the methods used to verify the authenticity of on-chain information.
