High level summary​

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

Some notable recent changes, updates or improvements include:

  • All environments have been upgraded to cardano-node 9.2.1.

  • Cardano-faucet 9.2 is available and deployed which is compatible with node 9.2.x and has fixed ipv6 functionality.

  • All deployed machines now default to nix 2.24-maint after an upstream bug causing a hash miscalculation in submodules has been fixed. Nix 2.21 forward required some rework of the colmena deployment recipes as dirty git trees now force an impure colmena deployment.

  • To ease the process of upgrading cardano-parts, releases will now be made instead of only PR merges with migration notes.

Repository Work​

Cardano-faucet​

  • Binds ipv6 interface in addition to ipv4, parses and logs all ips to a unified ipv6 format and applies hlint and fmt updates. cardano-faucet-pull-14

  • Makes required changes for cardano-api 9.2.0.0 and 9.3.0.0, removes void type sig constraints, bumps haskellNix, CHaP, cardano-api -> 9.3.0.0 for node 9.2.x compatibility. Disables mingw32 builds until alex in current haskellNix pin is updated. cardano-faucet-pull-15

Cardano-parts​

  • Sets cardano-node to 9.2.1, cardano-faucet to 9.2. Bumps nix to 2.24-maint and adds ipv6 and nix versioning fixes and other improvements.

Cardano-playground​

  • Deploys cardano-node to 9.2.1, cardano-faucet to 9.2. Bumps nix to 2.24-maint and adds ipv6 and nix versioning fixes and other improvements. Adds a wip node pparams api server. More detail is available in the PR description: cardano-playground-pull-33

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.
