Issuer revokes credentials

It does not have a US-X identifier like other User Stories

An issuer updates a credential in the

Algorithm

Goal

Get list of PSMHashes of subject

Assumptions

There are not assumptions, even if the subject does not exist, the return value will be an empty array

Steps

1. The actor (anyone in the network) initializes the client and executes GetSubjectCredentialsList given an address of the subject which will return the PSMHashes of the credentials.
2. Then, the actor will use GetSubjectCredentialStatus to retrieve the status of all the credentials.

Info: The Alastria ID framework is a complex specification that uses many technologies/layers. At least, it has the following layers: blockchain, JWTs(artifacts) and HTTP API. The official docs do not emphasize in its differences and its requirements and there is not really much documentation except for the JWTs (See other resources). Therefore, in this examples, there are some parts of the algorithm that are highly opinionated and others developers could implement in other ways.
