High-level overview of sprint 57​

We released cardano-node-8.9.0 (which includes ouroboros-newtork-0.12.0.0). This release contains the following network upgrades:

Soon we will release [cardano-node-8.9.1] (which includes ouroboros-network-0.12.0.0). This release will contain:

  • Peer sharing improvements & fixes. Contributed and tested by Karl Knutsson CF.
  • cardano-ping updates to support NodeToNode_V13 & peer sharing.
  • Some smaller maintenance changes.

The list of network features included in ouroboros-network-0.12.0.0 and ouroboros-network-0.13.0.0 can be found here.

We also continued working on tx-submission, ouroboros-network#3311. Mostly working on the pure internal API for decision-making and testing it with property-based tests. The next step is to get all the information needed to run the decision logic in an efficient way and later write a mini-protocol client which is using the new API and testing it.

We also started working on thing to finalise the Genesis support from the network. We have a PR under review, ouroboros-network#4832. We also started to investigate how to support big ledger peer snapshots. This requires changes in the topology file as well as cardano-node & ouroboros-network to understand the snapshots; and on the other hand creation of such snapshots by cardano-cli.

High-level summary​

This week, the Hydra team worked on aligning the specification with the current incremental decommit implementation, added decommit to model-based tests and also discussed the incremental commit protocol extension with researchers. The team also updated to cardano-api 8.40 and tests against cardano-node 8.9.0, which unblocked a possible release and re-enabled smoke tests on public networks. They also groomed a new /commit endpoint interface from a user discussion and discussed restructuring of the Hydra documentation. The team also prepared a Conway-supporting hydra-node on branch lc/conway-support for early adopters (Hi @Juantxu and @ash 👋). Some internal refactoring prepared for upcoming streaming plugins by SundaeLabs and minor fixes to the TUI and hydra-explorer rounded off the week.

What did the team achieve this week​

  • Aligned specification with current incremental decommit implementation and added Decommit to model based tests.
  • Discussed and explored further on incremental commits with researchers.
  • Refactored Event -> Input #1348 to prepare for streaming plugins #1325.
  • Minor fixes to the TUI and hydra-explorer clients.
  • Updated to cardano-node 8.9.0 and cardano-api 8.40 - this unblocked a possible release and re-enabled smoke tests on public networks.
  • Groomed new /commit endpoint interface #1350 from a user discussion #1337.
  • Discussed restructuring of the Hydra documentation #1349.
  • Prepared a Conway-supporting hydra-node on branch lc/conway-support #1178 (will be merged only after the hard-fork).

What are the goals of next week​

  • Prepare a PR for Kupo using new Hydra transaction format (to prepare for 0.16.0 release)
  • Review and merge streaming plugins #1325
  • Improve the /commit endpoint to unblock users
  • Test corner cases of incremental decommit transaction traces
