High level overview​

This week, the Mithril team started working on the decentralization of the Mithril networks with a proof of concept of peer-to-peer (P2P) networking between nodes. The team kept working on the adaptation of the Mithril client as a library, on the deterministic computation of the transaction history of an address from the immutable files, and on the refactoring that will fix the bottleneck of the key registration in the aggregator. Additionally, they published a security advisory for the Mithril relay.

Finally, they enhanced the CI/CD to publish multiple packages to crates.io and started improving the developer experience with the Mithril devnet.

High-level overview of sprint 46​

Bootstrap Peers​

We continued reviewing of bootstrap peers, see ouroboros-network#4555.

Towards Typed Protocols 0.2.0.0​

We diagnosed the performance regression of the new design. The work on typed-protocols will be postponed. For more details see the typed-protocols#3. As an outcome of the performance debugging we prepared PR which updates the demo-ping-pong and demo-chain-sync applications.

Peer Sharing​

We made progress in review of ouroboros-network#4644, which simplifies the peer sharing and fixes the ouroboros-network#4642 issue.

Tech Debt​

We reviewed the ouroboros-network#3836 PR which inspects all the uses of error in ouroboros-network. The PR was prepared by Galois.

High-level summary​

This week, the Hydra team's primary focus was on finalizing the new network resilience layer. This involved adding persistency to ensure data integrity.

They also completed the exploration of potentially moving the Plutus validator scripts to Aiken.

Additionally, the team dedicated some attention to our TUI by upgrading the Brick framework. They also undertook a comprehensive refactoring of the project's structure and addressed various bug fixes. These efforts are aimed at enhancing the overall user experience of our project.

What did the team achieve this week​

  • Network Resilience Persistence (#1101)[https://github.com/input-output-hk/hydra/pull/1101].
  • Upgrade brick on TUI (#1103)[https://github.com/input-output-hk/hydra/pull/1103].
  • Aiken commit validator translation (#1072)[https://github.com/input-output-hk/hydra/pull/1072].
  • Fixed some bugs in our TUI client.

What are the goals of next week​

  • Prepare presentation and workshop for Cardano Summit.
  • Work on hydra-poll dApp for Cardano summit.
  • Start the work on packaging hydra-node and related services.

High level summary​

The Ledger team has been shifting focus from implementing Conway related features to testing. For this reason there is a very little amount features that are reported this time aorund. Notable Conway related changes are a specialized ledger query for getting Constitutional Committee state and prevention of submitting proposal procedures that have no valid path to enactment.

Testing related work was mainly on a constraint base system as well as on roundtrip serialization. As a result of this extra testing a bug in Conway Genesis serialization was eliminated.

Integration and releasing​

Testing​

  • pull-3769 - Add roundtrip testing by validating FlatTerm
  • pull-3783 - Update TranslationInstance.hs
  • pull-3775 - Refactor and improve constraint based STS tests
  • pull-3793 - Fix sums with negative RHS.
