High level summary​

Major Enhancements​

  • Byron Genesis Support: Added capability to create Byron genesis files in the create-testnet-data command
  • HTTP Support for Anchor Data: Modified anchor-data checking to allow HTTP schema (with warnings) for testing purposes
  • Minting Script Witness Refactoring: Introduced MintScriptWitnessWithPolicyId as a first step toward deprecating ScriptWitnessFiles, making the code more maintainable and flexible
  • Code Sharing Improvements: Implemented shared code between genesis commands and query fields, reducing duplication and improving maintainability

API Enhancements​

  • Released cardano-api-10.3.0.0
  • Implemented and exported the Convert typeclass for better eon type conversion handling
  • Exposed functions for converting datums and scripts to JSON

The SRE team continues work on Cardano environment improvements and general maintenance.

Some notable recent changes, updates or improvements include:

  • Cardano-node release 10.1.3 was deployed to all environments

  • Dbsync release 13.6.0.2 and then 13.6.0.4 was deployed to all environments

  • Mainnet bootstraps have been configured for Cardano Foundation scrape, enabling a shared dashboard

Repository Work​

Cardano-node​

  • Ensures legacy tracing is default via config when the node default itself changes to new tracing system. Fixes default OCI mainnet topology p2p json. Updates some OCI legacy cmds and repo references. cardano-node-pull-6042

Cardano-parts​

  • Sets cardano-node to 10.1.3, dbsync to 13.6.0.4. Updates the default cardano-node nixos service to maintain legacy tracing when the default tracing system changes in the next node release. cardano-parts-release-v2024-12-02

Cardano-playground​

Cardano-mainnet​

  • Deploys cardano-node to 10.1.3, dbsync to 13.6.0.4. Adjust bootstraps for CF metrics scrape. cardano-mainnet-pull-27

Iohk-nix​

  • Ensure the use of legacy tracing for iohk-nix generated configs when the node binary defaults to new tracing. iohk-nix-pull-590

High-level summary​

These last few weeks continue on as before; almost wrapping up the incremental commit work. We are focusing on tests and soon the spec changes, which will be the last parts. We have integrated the core functionality into the TUI already, and also added a new requested feature around filtering by UTxO addresses to the websocket API. We continue on with the custom ledger experiments and wrapping up incremental commits, as well enhancing the hydra-explorer and supporting the upcoming Hydra Doom tournament!

What did the team achieve?​

  • Moved hydra-explorer out of the mono-repo #1716
  • Added ability to filter the API by UTxO address #1719
  • Finalising the work on incremental commits #199
  • Investigating customised ledger in a Hydra Head #1727
  • Investigated SQLite as our local datastore #1746
  • Incremental commits in the TUI #1747
  • Added a test to investigate a (potential) bug #1741

What's next?​

  • Hydra explorer supporting multiple versions #1282
  • Finish custom ledger experiment #1742
  • Plan the 0.20.0 release
  • Continue to imminent Hydra Doom tournament!

High level overview​

This week, the Mithril team released a new one-line installer for the pre-built Mithril binaries, simplifying the update process for SPO signers. They also published an overview of the protocol security on the documentation website. The team began implementing a new type of certification for the Cardano database to enable differential updates, scaffolding a new signed entity type, and progressing on the computation of the message to sign. Additionally, they adapted the WASM client npm package to support NodeJS and started working on a cache for certificate verification in the WASM client.

Finally, the team completed the removal of legacy store adapters from the codebase and explored solutions for signer registration in networks with multiple aggregators.
