What Is Agent Attestation?
An attestation is a signed statement by one party about a fact concerning another — "this agent passed this check", "this org controls this domain". It differs from a claim because it is signed by an identifiable attester who stakes their reputation, and it is evidence about an action rather than the action’s own record. Attestations compose into trust: the more independent, verifiable attestations about a party, the less a stranger must take on faith.
Evidence about, not the record of
An attestation is testimony, not the event. A verifier about an action and the action’s own record are different facts, and conflating them double-counts a single source. Trust is strongest when an attestation’s basis is independent of what it attests to — a witness whose evidence is byte-identical to the performer’s is one source counted twice.
Questions
Who can attest?
Anyone identifiable who will sign. The weight of an attestation comes from the attester’s standing and independence, not from the act of attesting.
Is an attestation a credential?
A credential is a kind of attestation about a holder. Both are signed statements; what matters is who signed and whether the subject-to-holder binding verifies.
