High-level overview of sprint 66
We held The Network Working Group (NWG) in the last sprint. Below, we share
recordings of this and earlier NWG meetings, which introduce basic notions of
ouroboros-network. These recordings should be accessible to a technical
audience.
Introduction to Ouroboros Network, NWG, part 1

Tx-Submission
We continued working on the new design of tx-submission. We progressed in writing
a new tx-submission server (inbound side of tx-submission protocol)
instrumented by decision logic. The next step is writing a simulation that
runs N-pairs of client-server communications in which the same decision logic governs all servers - emulating the behaviour of cardano-node once the new tx-submission is integrated. For more details, see
ouroboros-network#3311
Genesis integration
All outstanding PRs related to Genesis have been reviewed and accepted. Soon they will be merged.
- Big Ledger Peer Targets for Genesis - ouroboros-network#4832
- Feed peer selection governor with big ledger peers obtained from a snapshot - ouroboros-network#4850
- Introduction of serialization instances in support of ledger peer snapshot - ouroboros-network#4851
- Verification of big ledger peer snapshot file - ouroboros-network#4888
Mithril Integration
We presented ideas on how to run mithril functionalities with
cardano-node while taking into account the risks that such integration would impose on
the system. The technical description will be part of a CIP, which will then go to
the Technical Steering Committee (TSC) for an evaluation.
Smaller tasks
- Small improvements and bug fix in the Signal API, ouroboros-network#4909
- Improved memory foot-print of tests on ghc-9.8, ouroboros-network#4912
- Error cardano-ping whenever there's a decoding error, ouroboros-network#4916
Open-Source contributions
We found out and fixed a bug in the iproute parser of IPv4 addresses:
- Check that IPv4 addresses terminate, iproute#63
- IPv4 address with mask should not contain a white space, iproute#64
