Project Plan: Decentralized Identity Management for Data Sharing in Cacti

Abstract

Build reference decentralized identity registry based on Hyperledger Indy and identity-syncing protocols among permissioned DLTs using Group DIDs.

Mentors

Mentee

Communication channel:  Slack + Discord+ Github

Project repo: https://github.com/hyperledger/cacti

Deliverables

• Augment Indy Plenum with support for managing Group DIDs representing DLT networks
• Augment Indy SDK to add methods to create and manage Group DIDs
  • (Optional) Augment Indy VDR (future replacement for Indy SDK) to add methods to create and manage Group DIDs
• Create sample Indy testnet as model IIN (verifiable data registry) with support for maintaining Group DIDs and associated VCs
• Create trust anchor module built on Hyperledger Aries to represent a consortium that issues VCs to a group represented by a Group DID
• Upgrade Cacti Fabric IIN Agent to connect to an IIN and sync identities and certificates from another network
• Create Cacti Corda IIN Agent to connect to an IIN and sync identities and certificates from another network
• Write appropriate configuration files for IIN Agents, IIN Trust Anchors, and IIN testnet
• Update Corda CLI to launch IIN Agents
• Unit and Integration tests
• Update Decentralized Identity-related RFCs
• Write tutorial documents for users to configure and launch an IIN and appropriate IIN Agents for the participating DLT networks

Milestones

Eval 1:

• Research: understand Indy networks, DID and VC concepts, Indy SDK, existing Cacti-Weaver identity management protocols (RFCs)
  
• Update design specifications (RFCs) as required based on research output
  
• Implement: Indy Plenum support for Group DIDs (using partially existing code as the base)
  

Eval 2:

• Implement: Indy SDK support for Group DIDs
  
• Implement and configure: Sample IIN
  
• Implement: trust anchor module
• Publish Docker images for IIN and trust anchor modules

Eval 3:

• Implement: Fabric IIN Agents to depend on IINs and sync memberships (with unit tests)
  
• Demonstrate end-to-end data sharing for Fabric networks using IIN Agents
  
• Implement: Corda IIN Agents to depend on IINs and sync memberships (with unit tests)

Eval 4:

• Implement: Corda CLI support to configure and launch IIN Agents
• Write tutorial documentation to guide users
• Add appropriate Github Actions for integration testing
• TBD: Optional deliverables
