Create AnonCreds Credential Definition

Register a Credential Definition

After registering a schema, a credential definition can be registered based on the schema. The credential definition, amongst more things, binds the schema to a specific issuer. Schemas can be reused between issuers, but a credential definition is specific to an issuer. In a credential definition revocation can also be specified. This section will not go in-depth about revocation.

const credentialDefinitionResult = await agent.modules.anoncreds.registerCredentialDefinition({
  credentialDefinition: {
    tag: 'default',
    issuerId: '<did>',
    schemaId: schemaResult.schemaState.schemaId,
  },
  options: {
    supportRevocation: false,
  },
})

if (credentialDefinitionResult.credentialDefinitionState.state === 'failed') {
  throw new Error(
    `Error creating credential definition: ${credentialDefinitionResult.credentialDefinitionState.reason}`
  )
}

The request body must contain the credential_definition object with the Issuer DID and the Schema ID created in the previous steps.

To enable revocation, the options must contain the revocation flag, and the size of the revocation registry. Also, ensure that a Tails Server is configured for the issuer.
