Project Scope

The process of integrating the Cactus and Weaver modules and workflows to create a common Cacti platform conforming to the architecture illustrated in the Cacti Roadmap (and below) must follow a particular sequence of steps in order to ensure backward compatibility and avoid breaking preexisting user dependencies on exported Cacti packages and images.

As described in the project proposal, a number of Core Operator primitives for DLT interoperability have been identified.  They are:

• lockAsset
• pledgeAsset
• claimAsset
• generateProof
• verifyProof
• Noop

All three DLT interoperability use cases – data sharing, asset transfer, and asset swap – are a combination of the above primitives. 

The intention of this project is to unify multiple interoperability frameworks by creating a reusable set of operators so that the existing frameworks can be migrated to them.

Key Deliverables

• Cacti Core Operators Module, with grpc or socket IO external interface, and REST API integrated into the Cacti Client API. These operators are to be implemented in:

  • corda
  • hyperledger fabric
  • hyperledger besu
• CI-automated testing of Core Operator Module for all combinations

• Documentation of the above, including API documentation and getting started guide

• RFCs updated

Optional Deliverables

• Unified cacti CI github workflows
• Weaver tests run-able in local environment via docker
• Weaver test examples updated to use core operators
• Cactus REST APIs updated to use core operators
• Redundant code identified and removed
• Implementation of Core Operator Module in other DLTs
