Cryptographically Attested Data

Definition

Cryptographically attested data refers to information whose authenticity and integrity are verifiably guaranteed through cryptographic proofs. This involves a trusted entity or an oracle signing a data payload, often including a timestamp, with its private key. The signature then serves as an immutable, verifiable attestation that the data originated from the specified source and has not been tampered with. This mechanism establishes trust in off-chain information. It ensures data provenance and reliability.
