Augment Cacti Relay module to implement the IETF SATP (Secure Asset Transfer Protocol)
- Relay as asset source
- Relay as asset destination
Failover and recovery support in the Cacti Relay module
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)

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: Stage 1: Steps 1.1 - 1.4: happy path and error handling

Eval 2:

Eval 3:

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
