Proof response

Explanation of Proofattributes:

• ìd: This item is a unique identifier of the proof. It summarizes the content of the proof but not the authentication of its issuer. This attribute defines its position in the trust registry.

• commitment: This is the hash that guaranties integrity of the whole proof.

• commitment_details: These items are the intermediate values used to create and structure the commitment, they are sent to Archipels during the proof creation to validate integrity of the commitment.

• anchor_id: This value indicates in which batch the proof will be anchored on the Blockchain.

• status: When creating a proof, its status is first pending, then it becomes registered when the proof is included in the trust-registry and then it becomes included when the root of the trusted registry is anchored on the blockchain and fully timestamped and made immutable.

• metadata: These metadata are the values used to verify a proof. Each metadatum has a value which can be a hash or a standardized value of an input. It also has an inclusion proof that proves cryptographically that this value is included in the proofId. And it has a publication_flag which specifies how this metadata can be used during proof verification. If this flag is set to privatethen the metadatum is only used by Archipels for consistency checks. If the flag is set to public then the metadatum is sent to the verifier when a verification matches this proof. If this flag is set to searchable then the metadatum is only used to match with a proof verification.
