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. Begins cardano-parts date-based releases for an improved upgrade process. Adds misc fixes and improvements. More detail is available in the release notes: cardano-parts-release-v2024-10-07

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

Cardano-mainnet​

  • Deploys cardano-node to 9.2.1, bumps nix to 2.24-maint and adds ipv6 and nix versioning fixes and other improvements. Converts bootstraps to a new cached-index-patch branch and upgrades CF canary sql queries. More detail is available in the PR description: cardano-mainnet-pull-23

High-level summary​

This month we continued our work on incremental commits and blockfrost. We spent a bit of time conducting some experiments in ways to potentially improve our CI build times, and completed an encouraging spike around using Raft (via etcd) for our networking layer, among some other minor cleanups and version bumps. Up next We will continue on with incremental commits and blockfrost, as well as some items coming out of the Doom work, to improve our memory efficiency, and finally we will aim to move to PlutusV3!

What did the team achieve?​

  • Investigated CI improvements #1647, #1615
  • Updated networking documentation to reflect assumptions and present state #1649
  • Good progress on incremental commits #1522
  • Good progress on blockfrost integration in the Hydra node #1631
  • Update to use cardano-node 9.2.0 #1651
  • Investigated Raft for networking #1591
  • Grooming work on the partial fanout feature #1468

What's next?​

  • Continued work on incremental commit #199
  • Continued work on Blockfrost integration #1305
  • Improvements to memory usage #1618
  • Work towards moving to PlutusV3 #1665
  • CBOR datum on transaction outputs #1543

High level summary​

Over the past two weeks, we worked on establishing a first baseline for the Consensus QTA (#1256). This work is also helping inform discussions with the Networking team about sync performance goals in general and for specific improvements, such as Genesis.

UTXO-HD was rebased atop main and the tests are passing.

Finally, the team has also worked to improve the Consensus layer's robustness and security.

High level overview​

The Mithril team continued working on decentralizing the signature orchestration of the Mithril network. They completed the development of a mechanism to support specific configurations for signing Cardano transactions and kept implementing the autonomous computation of the messages to be signed by the signer. They also activated the certification of the Cardano transactions on the release-mainnet network.

Finally, they started creating a new Mithril era and prepared to upgrade to Cardano node version 9.2.1.

Low level overview​

  • Updated a dev blog post about the Certification of Cardano transactions
  • Completed the issue Aggregator advertises constant signing configurations for an epoch #1924
  • Completed the issue Breaking change in crane fails Hydra CI #1928
  • Completed the issue Discrepancy of protocol parameters in epoch settings and pending certificates routes #1963
  • Worked on the issue Signer computes what to sign on its own #1925
  • Worked on the issue Aggregator uses stored signing configurations when creating signed entity type #1961
  • Worked on the issue Prepare new Pythagoras Mithril era #1946
  • Worked on the issue Upgrade to Cardano 9.2.1 #1968

High level summary​

  • We continue to remove irrelevant eras from cardano-cli with an aim to simplify the Haskell code and the interface exposed to the user.
  • During a working group meeting a user pointed out the possibility to specify an incorrect anchor data hash. This has been largely rectified in cardano-cli but there is some more work to be done particularly in the transaction build command.
  • We added the possibility to specify supplemental datums and other minor improvements in this sprint.
