verifiable credential (concept) §
Defined in Verifiable Credentials Data Model v2.0: A verifiable credential is a tamper-evident credential that has authorship that can be cryptographically verified. Verifiable credentials can be used to build verifiable presentations, which can also be cryptographically verified.
verifiable credential graph (concept) §
Defined in Verifiable Credentials Data Model v2.0
verifiable data registries (concept) §
Defined in Verifiable Credentials Data Model v2.0: A role a system might perform by mediating the creation and verification of identifiers, verification material, and other relevant data, such as verifiable credential schemas, revocation registries, and so on, which might be required to use verifiable credentials. Some configurations might require correlatable identifiers for subjects. Some registries, such as ones for UUIDs and verification material, might just act as namespaces for identifiers.
verifiable presentation (concept) §
Defined in Verifiable Credentials Data Model v2.0: A verifiable presentation is a tamper-evident presentation encoded in such a way that authorship of the data can be trusted after a process of cryptographic verification. Certain types of verifiable presentations might contain data that is synthesized from, but do not contain, the original verifiable credentials (for example, zero-knowledge proofs).
VerifiableCredentialGraph (concept) §
Defined in Verifiable Credentials Data Model v2.0
verification method (concept) §
Defined in Verifiable Credential Data Integrity 1.0:

A set of parameters that can be used together with a process to independently verify a proof. For example, a cryptographic public key can be used as a verification method with respect to a digital signature; in such usage, it verifies that the signer possessed the associated cryptographic private key.

"Verification" and "proof" in this definition are intended to apply broadly. For example, a cryptographic public key might be used during Diffie-Hellman key exchange to negotiate a shared symmetric key for encryption. This guarantees the integrity of the key agreement process. It is thus another type of verification method, even though descriptions of the process might not use the words "verification" or "proof."

verification relationship (concept) §
Defined in Verifiable Credential Data Integrity 1.0:

An expression of the relationship between the subject and a verification method. An example of a verification relationship is 2.3.2.1 Authentication.

verifier (concept) §
Defined in Verifiable Credentials Data Model v2.0: A role an entity performs by receiving one or more verifiable credentials, optionally inside a verifiable presentation for processing. Other specifications might refer to this concept as a relying party.
verify (concept) §
Defined in Verifiable Credentials Data Model v2.0: The evaluation of whether a verifiable credential or verifiable presentation is an authentic and current statement of the issuer or presenter, respectively. This includes checking that: the credential (or presentation) conforms to the specification; the proof method is satisfied; and, if present, the status check succeeds. Verification of a credential does not imply evaluation of the truth of claims encoded in the credential.
