CI & project maintenance​

High level summary​

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

Some notable recent changes, updates or improvements include:

• Cardano-node 8.9.1 is now deployed to all environments.

• The legacy IOG mainnet metadata server has been retired with CF now providing metadata server services going forward.

• Cardano-parts PR#35, merged and linked below, offers ip information integration into nixosConfiguration modules as well as template-diff and template-patch recipes for easier upgrades going forward.

Lower level summary​

Capkgs​

• Adds a shortRev suffix to package names, fixes an rclone recipe, fixes a CI push action, defaults to recursively dereferenced object hashes, cleans up reference patterns. See the PR description for more details: capkgs-pull-2

Cardano-mainnet​

• Bumps to cardano-node 8.9.1 and deploys all machines, makes ip information available in nixosCfgs, adds new expected machine alerts, tunes snapshot alerts and implements all updates in cardano-parts PR#35. See the PR description for more details: cardano-mainnet-pull-10

Cardano-ops​

• Bumps to cardano-node 8.9.1, removes the legacy metadata server: cardano-ops-commit

Cardano-parts​

• Upgrades cardano-node to 8.9.1 for both release and pre-release, integrates machine ip information into nixosConfigurations, enables /etc/hosts file usage in cardano-node topology, enhances cardano-node topology producer generation with customizable address types, introduces template patching recipes for easier cardano-parts updates to existing clusters. Much more detail is available in the PR description: cardano-parts-pull-35

Cardano-playground​

• Bumps to cardano-node 8.9.1 and deploys all envs, rotates KES keys in most envs, makes ip information available in nixosCfgs and implements all updates in cardano-parts PR#35. See the PR description for more details: cardano-playground-pull-18

High-level summary​

This week, the Hydra team conducted the monthly review meeting and investigated a broken head situation. The team slightly improved conway forward compatibility in explorer / hydra-node, enhanced hydra-cluster --devnet which allows e2e testing of kupo, extended smoke test to also include committing ADA into the head, documented the anticipated behavior of incremental decommits, and added decommits to the tutorial.

What did the team achieve this week​

• Conducted the monthly review meeting (link to recording already?)
• Investigated a broken head situation #1374
• Slightly improved conway forward compatibility in explorer / hydra-node #1373
• Busy hydra-cluster --devnet sandbox which allows e2e testing of kupo #1378
• Extended smoke test to also include committing ADA into the head #1377
• Documented the anticipated behavior of incremental decommits and added decommits to tutorial
• Another write-up of how the incremental commit/decommit could work (without needing merkle trees or L2/L1 interleaving) on this issue

What are the goals of next week​

• Complete the written monthly report
• Update our head and hydraw instance to master (a release candidate)
• Complete the improved /commit endpoint to unblock users
• Release 0.16.0 (likely without incremental decommits)
• Reproduce close > contest > contest scenarios using stateful testing

High level summary​

We continued focusing on adding tests and improving the test frameworks, including the quality of the generated data used in tests.

High level overview​

This week, the Mithril team released a new Mithril distribution 2412.0. This release includes several critical updates and enhancements, such as support for the Prometheus metrics endpoint in signer, deprecation of the snapshot command in the client CLI, full Pallas-based implementation of the chain observer, and support for Cardano node v.8.9.0.

The team continued implementing the certification of Cardano transactions in Mithril networks. They focused on scaling the signature and proof generation for mainnet, kept implementing a more versatile beaconing mechanism, reducing the latency of transactions signature, and continued investigating a bug in the block parser that prevents some Conway transactions from being signed. Additionally, they started working on a prototype to decentralize signer registration with the relay and a peer-to-peer (P2P) network.

Finally, the team completed the implementation of some community-requested features to verify the output folder structure made by the client, and kept investigating a source of flakiness in the CI end-to-end test.
