The full reference list lives in the glossary. The terms below are the minimum vocabulary needed to read the protocol pages.
- Seal
- A tamper-responsive cryptographic device physically attached to a reserve unit. Holds a non-exportable signing key that is destroyed or disabled on tamper detection.
- Lot
- A discrete, inspected unit of physical commodity (e.g. a sealed container of urea fertilizer).
- Registry
- An append-only record that binds seal identities to inspected lots, plus revocation and status data.
- Verifier
- A party that challenges a seal and checks the resulting signature, registry status, and any claim constraints.
- Auditor
- A third party that examines inspection, custody, and registry records to validate the integrity of CPHAR deployments.
- Reserve claim
- A statement that some set of registered lots, attested by live seals, satisfies a property (e.g. "≥ N metric tons").
- Proof bundle
- A packaged set of attestations, registry references, and optional zero-knowledge proofs that supports a reserve claim.
- Revocation list
- Published record of seal identities that should no longer be trusted (e.g. retired, lost, suspected compromise).
