StatusList2021Entry

StatusList2021Entry is a credentialStatus method by which the status of a verifiable credential can be checked. The basic idea of it is each issued credential has a corresponding position in a bit-string (also called the status list), having a value of either 0 - not revoked, or 1 - revoked. This status list is published by the issuer as a verifiable credential with a type that includes StatusList2021Credential.

The StatusList2021Entry credentialStatus contains the following fields:

id - a URL identifying the status information for the verifiable credential
type - StatusList2021Entry
statusPurpose - the purpose of the status entry (typically revocation or suspension)
statusListIndex - the bit position of the credential within the bit-string
statusListCredential - the URL of the StatusList2021Credential credential that encapsulates the bit-string

e.g.

{
  "id": "https://example.com/credentials/status/3#94567",
  "type": "StatusList2021Entry",
  "statusPurpose": "revocation",
  "statusListIndex": "94567",
  "statusListCredential": "https://example.com/credentials/status/3"
}

StatusList2021Credential

The StatusList2021Credential is a verifiable credential that encapsulates the bit-string information about all the credentials ever issued. The following fields have to be explicitly provided:

id - (optional) the URL to this credential (should match the statusListCredential value from StatusList2021Entry)
type - should contain StatusList2021Credential
credentialSubject
- type - StatusList2021
- statusPurpose - the purpose of the status credential (StatusList2021Entry should match this value)
- encodedList - the compressed and base64 encoded value of the bit-string

e.g.

{
  "id": "https://example.com/credentials/status/3",
  "type": ["VerifiableCredential", "StatusList2021Credential"],
  "credentialSubject": {
    "id": "https://example.com/status/3#list",
    "type": "StatusList2021",
    "statusPurpose": "revocation",
    "encodedList": "H4sIAAAAAAAAA-3BMQEAAADCoPVPbQwfoAAAAAAAAAAAAAAAAAAAAIC3AYbSVKsAQAAA"
  },
  "other-verifiable-credential-properties": {}
}
