What is an issuer?

An Issuer is any entity that issues Verifiable Credentials (VCs), which can be thought of as statements or claims made about another subject or entity. For example, when the Driver and Vehicle Licensing Agency (the Issuer) asserts that an individual (the subject) holds a driving license, this constitutes a credential. Anyone can be an issuer:

  • An online community saying you're a member.

  • The government giving you an official ID.

  • A smart camera confirms you're a person.

  • Your company is vouching for your skills or employment.

Although anyone can function as an Issuer, the acceptance of their credentials depends on the Verifier's judgment. That judgment might be based on the reputation or the legality of the Issuer and, if applicable, the relevance of the claim and all other information the verification tool provides.

The cryptographic signature on the public blockchain ensures the integrity and validity of the signature. Yet, not every credential holds equal weight. The Verifier discerns the legitimacy of the Issuer and the credibility of their credential, akin to acknowledging that while someone, like one's mother, may vouch for one's driving abilities, the authorities may not necessarily validate such a credential. Ultimately, Verifiers wield the authority to affirm, "Indeed, this credential is legitimate and trustworthy."
