  • State machine serialization approach and philosophy
    • https://github.com/hyperledger/aries-vcx/issues/742
    • https://github.com/hyperledger/aries-vcx/issues/745
    • question: should serialized format be considered opaque to users?
  • Discussion conclusion:
    
    • Serialized state machines should be considered opaque - users should not rely on the serialization structure, it might change in the future.
    • However, users can rely on ability to deserialize state machine from previous version of vcx, even if change in serialization format occurs
    • We will include from_parts  , to_parts  type of API on state machines, as it existed on MediatedConnection  

Task backlog: 

• • Reduce cloning in messages, diddoc  crates
  • Replace some of macros (for example threadlike_optional) with traits instead
  • Apply State pattern for issuance, presentation state machines
  • Issuer with credx
  • Decoupling: Extract protocols  crate https://github.com/hyperledger/aries-vcx/issues/698
  • Refactoring: Unify state machine interface approach https://github.com/hyperledger/aries-vcx/issues/696
  • Enable OOB tests in AATH https://github.com/hyperledger/aries-vcx/issues/678
  • Eliminate usage of MediatedConnection in tests
  • DDO as first class citizen
  • Add more typing across codebase
  • New protocols: DidExchange protocol, Presentation Protocol 2.0, Issuance Protocol 2.0
