Lower level summary​

Cardano-parts​

  • Sets cardano-node|cli-ng to 8.10.0-pre, dbsync-ng to sancho-4.1.0; bumps nixpkgs (23.11) and nixpkgs-unstable; improves, adds new and fixes a number of just recipes; allows repo custom recipes to be kept as a separate import for easy justfile maintenance; refactors ip module checking into its own nixosModule and adds an extra abort option for safety. Much more detail is available in the PR description: cardano-parts-pull-36

High level overview​

This week, the Mithril team continued implementing the certification of Cardano transactions in Mithril networks. They focused on scaling the signature and proof generation for mainnet, completed the incremental storage of transactions, activated the signature of the transactions on the testing-preview network, and prepared a new network to test the scaling on mainnet data. The team also made progress on a prototype for decentralizing signer registration with the relay and a peer-to-peer (P2P) network. Additionally, they worked on refactoring the database providers of the aggregator.

Finally, the team delivered a community requested feature that displays the minimum versions of the Cardano node that the signer supports in a machine-readable format. They also provided a manual setup guide for the relay in the SPO user guide.

  • Completed the issue Implement incremental storage of Cardano transactions in signer/aggregator #1591
  • Worked on the issue Mithril relay broadcasts signer registrations with P2P PubSub #1587
  • Worked on the issue Refactor database module in aggregator #1583
  • Worked on the issue ChainObserver supports retrieving the Chain Point of the tip of the chain #1589
  • Worked on the issue Create file with Cardano minimum versions in repository #1615
  • Worked on the issue Deploy testing-mainnet network #1617
  • Worked on the issue Add section for manual setup of squid in SPO guide #1610
  • Completed the issue Signer metrics server displays confusing log message #1620

High-level summary​

This week, the Hydra team released hydra 0.16.0, which supports cardano-node 8.9.0 and can interpret conway blocks on the cardano-node. We have also updated some hydra clients to be compatible with the new hydra api format, including hydraw and kupo.

What did the team achieve this week​

  • Update our head and hydraw instance to master (a release candidate)
  • Release 0.16.0 (without incremental decommits)
  • Reproduce close > contest > contest scenarios using stateful testing
  • Have end-to-end scenarios working for the improved /commit endpoint

What are the goals of next week​

  • Complete the improved /commit endpoint to unblock users
  • Potentially release 0.17.0 (with improved /commit endpoint)
  • Wrap up the incremental decommit work including the decommit action into the new TxTrace tests
  • Use Versioned Ouroboros protocol for handshaking between nodes.
  • Update to cardano-api-8.44.

High level summary​

  • Made the LocalTxMonitor HasTx cross-era behavior less surprising.
  • Finalized the tests in ouroboros-consensus for the UTXO-HD branch, except the mempool-parallel test which is still failing sometimes.
  • Fixed an upstream complication in quickcheck-state-machine related to Parallel state machines which should allow us for an easier and more understandable setup of the parallel mempool tests.
  • Drafted parallel state machine testing infrastructure for quickcheck-dynamic. Eventually could be used to replace the QSM infra for mempool parallel tests.
  • Cleaned up the Cardano.API.LedgerState module, required for UTXO-HD integration.
  • We have been working on Node release 8.10. The changes upstream are integrated all the way to Node. Tests and benchmarks are pending. The versions of Consensus, Ledger, and Networking are released, and we will focus next on releasing CLI, API, and finally Node.
