Overview of sprint 93​

Tx-Submission​

We deployed our tx-submission work (see Issue#3311 based on the cardano-node-10.5 release. The node has been working without any problems.

Mithril​

We prepared two PR which will allow us to capture raw bytes alongside decoded data structures. This is essential for checking signatures as well as avoiding re-serialisation of signed data:

These PRs are in review.

We now have a dmq node with the following capabilities:

  • can disiminate signatures, but not validate them in any way, although one cannot submit signatures (/work in progress/)
  • discover peers (with peer-sharing mini-protocol)
  • control connections through keep-alive mini-protocol
  • configuration file which allows setting diffusion options, setting up traces, etc.
  • basic logging system

In the current state of development, we were able to connect two dmq nodes and observe keep-alive messages. In the next stage, we will be able to submit signatures and observe how they are diffused through a network of dmq nodes.

Connection Duration​

We added a trace point which allows one to see how long a connection lived, see PR#5146.

Release of ouroboros-network-0.22.1​

We released ouroboros-network-0.22.1. It is already integrated with ouroboros-consensus and it will be included in cardano-node-10.6. See release-board.
