The mission of the W3C Credentials Community Group is to explore the creation, storage, presentation, verification and user control of credentials. The group focuses on a verifiable credential created by an issuer about a subject (a person, group, or thing) and seeks solutions inclusive of approaches, such as self-sovereign identity, presentation of proofs by the bearer, data minimisation, as well as centralised, federated and decentralised registry and identity systems. The group is drafting and incubating Internet specifications for further standardisation and prototyping and testing reference implementations.
