Description:

The Hyperledger implementation of self-sovereign identity (SSI) is traditionally associated with CL AnonCreds verifiable credential format, Hyperledger Aries exchange protocols based on DIDComm and a Hyperledger Indy ledger as a verifiable data registry (VDR). These are mature technologies used in production systems. Hyperledger Indy and CL AnonCreds played a key role in shaping self-sovereign identity before the establishment of various other SSI standards and specifications.

Nowadays such specifications as W3C VC, OpenID for Verifiable Credentials (OIDC4VC), SD-JWT and others gain increasing attention due to plans for adoption by European Digital Identity Architecture and Reference Framework, NIST, DHS etc. Moreover, although Indy Ledger is a great and proven VDR option for permissioned cases, nowadays permissionless proof-of-stake ledgers can be a reasonable alternative, as well as other distributed ledger technologies (DLT) from the Hyperledger family.

The main goal of the workshop is to invalidate a misconception that Hyperledger Aries SSI projects can only work with CL AnonCreds, DIDComm and Indy Ledger. We are going to apply Credo (Agent Framework JavaScript) for issuance and verification of Verifiable Credentials in W3C format, use OIDC4VC for credentials exchange, and leverage external permissionless ledgers as a VDR. Moreover, we are going to show a synergy between two graduated Hyperledger projects: Aries and Besu. It will be done by means of a new Indy-Besu effort and repo.

This workshop will be livestreamed and recorded. 

Prerequisites:

For the hands-on, we are going to use a Gitpod profile, which you can log into through your GitHub account.

• Join GitPod here
• We ask all participants to make sure that they have at least a few hours of workspace usage in their Gitpod profile to participate in the hands-on. You can check this using this link: https://gitpod.io/billing
• Recommended browsers: Chrome or Firefox.

Agenda:

The planned agenda consists of three main parts:
Presentation:
• Decentralized Identity (SSI) Overview
• Overview of SSI standards involved into demonstration (W3C VC, CL AnonCreds, OIDC4VC, Aries,
etc.)
• Overview of SSI frameworks involved into demonstration (Hyperledger Indy, Agent
Framework JavaScript, Hyperledger Besu, cheqd, Cardano, etc.)
Demo:
• Non-Indy VDR + CL AnonCreds: Hyperledger AFJ + Cardano as VDR
• Non-Indy VDR + W3C VC: Hyperledger AFJ + cheqd as VDR
• OIDC4VC in Hyperledger AFJ
Hands-on:
• Non-Indy VDR + CL AnonCreds: Hyperledger AFJ + Hyperledger Besu (Indy Ledger 2.0) as VDR
• Non-Indy VDR + W3C VC: Hyperledger AFJ + Hyperledger Besu (Indy Ledger 2.0) as VDR
