  1. In Hyperledger Indy roles are assigned to agents rather than nodes. Agents however are implemented in hard coding (Python, Go, JS) which interact with the ledger.

    • As an example in application built on top of Indy there could be defined following roles: Steward, Trustee, or Endorser and assign permissions to each role.

    • Following example is the small part from one of my projects, where AnchorHandle class serves as a wrapper for interacting with ledger using Indy SDK, and there I used INDY_ROLE_TYPES to map specific role ID to role names in Indy environment:

      INDY_ROLE_TYPES = {
        "0": "TRUSTEE",
        "2": "STEWARD",
        "100": "TGB",
        "101": "TRUST_ANCHOR",
      }

    • And in the following example which is the part of web server to interact with Indy ledger role information is retrieved from a transaction data and converts the role ID into role name:

      role = data.get('role')
if role != None:
role_name = INDY_ROLE_TYPES.get(role, role)
text.append("ROLE: " + role_name)

  2. And to learn how the Indy environment works and how to assign roles you can follow these:

    • In the following link - you will find Default AUTH_MAP Rules where you can check description for each of them.
    • Sovrin Glossary - which helps to understand the meaning of the terms
    • Indy official documentation - you have to read and analyze each part for better understanding and interacting with Indy SDK
    • Regional-Communities - lastly, here you can find regional communities, where you can also get experienced level help.
