Project Plan: Implement the Secure Asset Transfer Protocol in Cacti

Abstract

Implement the IETF Secure Asset Transfer Protocol according to proposed drafts (precursor to official RFCs) in Cacti using Relays.

Mentors

Mentee

Communication channel:  Slack + Discord+ Github

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

Deliverables

• Augment Cacti Relay module to implement the IETF SATP (Secure Asset Transfer Protocol)
  
  • Relay as asset source
  • Relay as asset destination
• Augment Fabric driver to handle SATP asset transfer instructions received from relays
• Augment Fabric Interoperation SDK to trigger and manage asset transfers using SATP
• Augment Fabric CLI to run and demonstrate an end-to-end instance of asset transfer
• (Optional) Augment Corda Interoperation SDK to trigger and manage asset transfers using SATP
• (Optional) Augment Corda CLI to run and demonstrate an end-to-end instance of asset transfer
• Demonstrate asset transfers across Fabric networks using the SATP
• (Optional) Demonstrate asset transfers across any combination of Fabric and Corda networks using the SATP
• Unit and Integration tests
• Write RFCs around the design and implementation of SATP using relays (final design specs will be an outcome of experimentation, and will be adjusted to reflect the latest IETF SATP draft specs.)
• Write tutorial documents for users to configure and run testnets and applications and move assets across them
• Propose updates to the IETF SATP drafts
• (Optional) Port SATP logic from Relay to Node Server (older implementation using ODAP)

Milestones

Eval 1:

• Research: understand the SATP by reading the drafts, read about distributed commit protocols, get hands-on with relay and driver code within Cacti
• Implement: basic relay support for round-trip messaging
  
• Implement: Steps 2.1 - 2.3, with Stage 1 bootstrapping

Eval 2:

• Implement: remainder of the steps: 2.4 - 3.10
• Implement: Fabric Interoperation SDK support

Eval 3:

• Implement: Stage 1 of the SATP
• Implement: Fabric CLI additions to orchestrate asset transfers using this protocol
• Demonstrate asset transfer across Fabric networks
• Write tutorial documentation to guide users
• Add appropriate Github Actions for integration testing

Eval 4:

• Write design specifications (RFCs) for SATP-based asset transfer

• TBD: Optional deliverables
