Attestation
Also known as: Digital Proof, Verifiable Claim, Credential Confirmation
A signed confirmation verifying a claim or event, used in identity, staking, and cross-chain communication.
Attestation is a digital proof that confirms the validity of a claim, event, or piece of data in blockchain systems. It is commonly used in decentralized identity (DID), staking protocols, oracles, and cross-chain bridges. An attestation may include cryptographic signatures, metadata, and timestamps, ensuring non-repudiation and auditability. In staking, validators issue attestations to prove participation; in identity, issuers confirm credentials. Standards like W3C Verifiable Credentials and EIP-712 support structured attestation formats for on-chain and off-chain interoperability.
