9/12 working on transport layer: move to code more suited to monix task
submitted pr to monix repo and waiting for review and merge
adds new dependency
9/14 ASK did the monix pr get merged? No. We will need to choose another solution: Idea to clone the repo and make dev team contributors to it. Update it and add to Maven. QUESTION how would this be handled on the SBT side? Not an issue. It would be deployed in Maven central. DECISION agreement to factor out and create a repo for the gRPC-monix work (repo, collaborators, and add to Maven). QUESTION how does Maven update? Tag a new release and deploy to Maven. Sebastian will do on Mon.
9/14 temporary solution copied code from GRPC-monix to rchain/rchain
