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.

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 implementation of a more versatile beaconing mechanism, worked on implementing incremental storage of transactions, and fixed the bug in the block parser that prevented some Conway transactions from being signed. Additionally, they continued working on a prototype to decentralize signer registration with the relay and a peer-to-peer (P2P) network.

Finally, they enhanced the internal storage of data on the test aggregator server and addressed a source of flakiness in the CI end-to-end test.
