2020-04-23 Iroha 2 status meeting notes

@Nikita Puzankov

• Found the root cause of bug in networking, related to the lost of some bytes. Now it is fixed.

• Made PR with signatures validation mechanism. There is a validation for incoming transactions. Also I am working on stateful validation by copying WSV and try to apply transaction on that copy. 

• Then I will join @Egor Ivkov and help him on finishing p2p networking and Sumeragi implementation.

@Andrei Lebedev

• Totally occupied by the 1.2 release finalization 

@Egor Ivkov

• Working on Sumeragi implementation, draft PR is posted.

• Will continue work on Sumeragi further.

• We will need to make Torii as a single point for all networking communication

• After confirmation for RFC we can switch to implementation

• Makoto> For Sumeragi it is make sense to implement the basic flow without error handling

  • On the first PR I will do only basic scenario, and then continue with improvements according to the special situations

• Makoto> Test framework may help us a lot in describing and checking the special situations

  • Kamil> You can take a look on the Grandpa consensus implementation to make the consensus more testable.

  • I will look on it and try to follow that level of abstraction

@Kamil Salakhiev

• Keeping an eye on the chat and PRs

• Do not have time for exchange protocols research, will continue it later

• Makoto> About Interchain: I talked about some people in Polkadot community, and there is a new approach proposal provided for the exchange behavior. 

• Makoto> I think way is that we have used in D3. We should do more research here

@武宮誠

• Continue working on DSL design. I have created the Python file with experiments. Next week I will be able to show something.
