Credentials

A credential is an attestation that an attester makes about a subject: a type (for example investor.accredited), an expiry, and optionally a 32-byte evidence hash. It carries no personal data — the evidence stays with the attester; the chain only stores its hash.

Credentials do nothing on their own. They matter when a policy asks for one: CREDENTIAL(type, attesters) allows a recipient who holds a valid attestation of that type from one of the listed attesters.

  • One record per (subject, type, attester). Attesting again replaces the expiry and evidence and clears a revocation.
  • Only the attester can revoke its own record; the record is kept with revoked = true.
  • Self-attestation is allowed: whose attestations count is the policy’s decision, through its attesters list.
  • Validity is checked when units move. Revoking or expiring a credential does not take units away from anyone who already holds them.
