High level summary​

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

Some notable recent changes, updates or improvements include:

  • Cardano-parts environments can now be migrated from Grafana Agent to Grafana Alloy.

  • Most cardano-parts downstream clusters have now been migrated to grafana alloy use.

Repository Work​

Cardano-parts​

  • Migrates to grafana alloy from grafana agent. Drops deprecated cardano-node service features and iohk-nix legacy mainnet relay filtering. Fixes cardano-parts jobs for cardano-cli breaking change compatibility. More detail is available in the release notes: cardano-parts-release-v2024-10-22

Cardano-playground​

  • Migrates to grafana alloy for metrics collection, rotates sanchonet kes, fixes latest govtool develop nix packaging and nginx deployment and deploys to sanchonet. More detail is available in the PR description: cardano-playground-pull-34

Cardano-mainnet​

  • Migrates to grafana alloy for metrics collection, fixes scheduled restart service status file. More detail is available in the PR description: cardano-mainnet-pull-24

Cardano-node​

  • Removes legacy mainnet relay filter for bootstrap attr generation, bumps the iohkNix pin for similarly updated topology generation, updates mainnet topology config to match updated iohk-nix topology ordering. cardano-node-pull-6011

Govtool​

  • Fixes nix builds for frontend and backend components, required node_nixpkgs pin update and regeneration of yarn.lock. Fixes impure nix builds required by some deployers by adding an optional returnShellEnv bool to the backend package. govtool-pull-2184

Iohk-nix​

  • Removes deprecated legacy relays from mainnet env and corresponding filtering for bootstrap generation, simplifies bp config generation, arranges mainnet edgeNodes in alphabetical order. iohk-nix-pull-587

High-level summary​

The last few weeks have seen a solid amount of work and changes to the user-facing side of Hydra; namely great progress on incremental commits and using Aiken for our commit validator which has yielded size/cost savings. This has also allowed us to support PlutusV3 validators and keep up to date with the cardano-api. We also made a breaking change (improvement) to the server output SnapshotConfirmed to make it easier to work with signed snapshots. Finally, we made good progress on blockfrost support by adding an option to follow the chain via blockfrost, instead of through a cardano-node. Next up we continue our focus on incremental commits and general improvements, while planning the next release.

What did the team achieve?​

  • Added the raw CBOR datum in transaction outputs #1543
  • Used Aiken for commit validator #1680
  • Updated to cardano-api 9.4 #1706
  • Implemented the off-chain user journey for incremental commits #1522
  • Documentation on the incremental commits feature #1704
  • Some cleanup of unused modules and functions
  • Full transaction information in SnapshotConfirmed event #1685
  • Added blockfrost mode to hydra-chain-observer #1631

What's next?​

  • Continued work on incremental commits #199
  • Improvements to memory usage #1618
  • DevEx improvements to split out components of the hydra monorepo
  • Start to plan the 0.20.0 release

High level overview​

The Mithril team completed decentralizing the signature orchestration of the Mithril network. They also completed refactoring the Prometheus metrics in the signer and started implementing them in the aggregator. Additionally, the team kept working on supporting the new Pythagoras Mithril era and created the new distribution pre-release 2442.0-pre.

Finally, they kept implementing optimizations on the node logs and enhanced the release creation workflow in the CI.

High level summary​

  • More anchor data hash checks were added to cardano-cli commands.
  • Support to create certificates that can register and delegate stake.
  • Moved various era agnostic commands to the top level of cardano-cli.
  • Added Cardano.Api.Tx.Compatible to cardano-api which allows the creation of simple unbalanced transactions that can submit protocol updates in any era.
