Verifiable credentials (or VCs) are a standard format for the digital representation of credentials (documents that collect attributes about a subject) that are cryptographically secure, verifiable through machines, and that guarantee privacy by enabling methods such as minimum disclosure. |
VCs can be used to describe identity credentials, such as academic diplomas, driver’s licenses, passports, insurance cards, vaccination records (and so much more).
Verifiable Credentials are formed by three components:
Credential Metadata: Properties or attributes of the credential that reference the holder (or user), the issuer, associated DIDs, the issue date, and the expiration date.
Claims: A statement about a subject (individual, legal entity, or thing).
Proofs: Cryptographic signatures tied to private keys that prove the user sharing the VC is the subject of the information.
...
To ensure credentials are shared and interpreted correctly, each of these credentials requires a template.
The issuance template is the general structure of the credential and conveys what information must be included on the credential in order for it to be valid.
Below you can see the step-by-step tutorial on how to issue your first credential.
