      • Project roadmap: #38

      cta-frontend-grpc integration for CTA


      • Michael changed cta-frontend-grpc protocol buffer, to make it similar to the current CTA protocol. This will make it easier to migrate to the gRPC implementation in the future.

      • Protocol buffer implementation will be reviewed by Jacek/Michael when back from holidays.

      • Interface that parses the commands will also be refactored so that it is the same between ssi and grpc implementations.
