WIRE TYPES

ar.attestation.v1 (issuance)

Records the issuance of a qualified trust service artifact — the service type (QES, QESeal, QTSA, QWAC, or EAA), the issuer identity on the Trusted Service List, and TSL snapshot evidence. TSA MANDATORY when service_type is qualified.

ar.attestation.v1 (revocation)

Records the revocation of a previously issued trust service artifact. Chains from the issuance receipt — verifier confirms the predecessor exists and was signed by the same issuer.

WHAT IT PROVES

  • — A trust service artifact was issued by an entity listed on the EU Trusted Service List at issuance time (TSL snapshot evidence).
  • — The issuance or revocation happened before a specific UTC date (MANDATORY TSA on qualified issuance).
  • — The complete lifecycle — issuance and any subsequent revocation (chain walk).
  • — The issuer's TSL status at the time of issuance (snapshot hash in body).

WHAT IT DOESN'T PROVE

  • — The artifact's content is true or accurate — only that a QTSP issued it.
  • — The issuer remains on the Trusted Service List after issuance.
  • — The relying party correctly validated the artifact.
  • — The underlying identity verification was thorough.
