Project Plan: Data Sharing from Besu/Ethereum in Cacti

Abstract

Augment existing modules and add new adapters to enable data sharing to and from networks built on Hyperledger Besu and Ethereum.

Mentors

Mentee

Communication channel:  Slack + Discord+ Github

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

Deliverables

• Create components for a Besu network to be able to participate in data sharing:
  • Besu driver for view and proof generation
    
  • Besu interoperation module: access control
    
  • Besu interoperation module: membership management
  • Besu interoperation module: proof generation
  • Besu interoperation module: proof verification
  • Besu Node.js SDK for triggering data sharing flows
    
  • (Optional) Besu IIN Agent for membership syncing
• Augment Fabric interoperation chaincode to accept and validate Besu proofs
• Augment Corda interoperation CorDApp to accept and validate Besu proofs
• Write appropriate configuration files: relay, access control policy, verification policy, membership info for Besu network
• Update Besu CLI to orchestrate and test end-to-end data sharing flows with at least one Besu network
• Unit and Integration tests
• Write RFCs detailing specifications of Besu-related components, compiling research and design specifications
• Write tutorial documents for users to launch and configure Besu networks and run end-to-end data sharing examples
• (Optional) Port interoperation module for use with Ethereum Mainnet: to generate proofs from Ethereum
  
• (Optional) Port Besu driver to work with the Ethereum mainnet to generate proofs from Ethereum
• (Optional) Add encryption and authentication logic in Besu interoperation module for end-to-end confidentiality
  
• (Optional) Add decryption and authentication logic in Besu SDK for end-to-end confidentiality
