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 explorer is being sunset and will soon be replaced by a new Cardano Foundation explorer
  • IOG mainnet pools are now participating in propagation time reporting using Cardano Foundation's blockperf tool
  • Cardano-parts node nixosConfigurations, node entrypoint and process-compose node jobs now utilize mithril client automatically on preview and preprod networks for faster synchronization of first start up. Mainnet mithril client use as well as signer modules will be available soon.

Cardano-parts​

  • Adds a block performance module which utilizes cardano-foundation's blockperf for aggregate block propagation reporting: cardano-parts-pull-29
  • Adds a mithril client for nixosConfigurations, process-compose cardano-node processes and cardano-node entrypoint: cardano-parts-pull-30

Iohk-nix​

High-level Summary​

This week, the Hydra team authored and published the monthly report for January 2024, enhanced user feedback for failed commands, updated cardano-api dependency and GHC to newer versions, re-opened their persistent head in preparation for the hard-fork, extended the model-based testing suite to cover the closing of heads, fixed a bug in io-sim, and contributed to cardano-node.

What did the team achieve this week​

What are the goals of next week​

  • Fix the fanout after contest bug #1260
  • Run Hydra smoke tests on sanchonet #1257
  • Specify the on-chain validators for incremental decommits #1057
  • Have the explorer hosted #696
  • Prepare PRs for dropped JSON instances from API #1213

High level summary​

One very important Conway feature that became available since last report is the ability for Stake Pool Operators to vote on some of the security relevant protocol parameter updates. We organized proposal hierarchy into a cohesive implementation, which together with good tests gives us confidence in its correctness.

We also fixed a few important bugs:

  • Preventing Constitutional Committee Members from voting on governance actions that they should not be allowed to vote on.
  • Prevent deposits from appearing in orphaned reward accounts after the staking credential has been unregistered, but before the proposal procedure deposit has been returned.
  • Ensure Sets are encoded in CBOR with tag 258 by default

Further improvements in testing tools and addition of more tests.

Low level summary​

  • pull-3982 - Added SPO voting thresholds for security relevant parameters
  • pull-3978 - Proposals pruning rewrite
  • pull-4003 - Prefix Set encoding with tag 258
  • pull-3999 - Add PParamUpdates to the plutus context, by transforming them to Plutus Data
  • pull-4008 - Fixed a bug in GOV rule
  • pull-4013 - Remove EnactState from ConwayGovState
  • pull-4025 - Further improvements to Proposals

High level overview​

This week, the Mithril team continued implementing a new data type for certifying Cardano transactions within Mithril networks. They completed the signature of the transactions set and implemented the aggregator route, responsible for generating proofs of membership for a list of Cardano transactions. Additionally, they finalized the manual workflow to test the NPM client package in the CI and enhanced the resilience of computing the list of immutable files in a Cardano node database. The team also expanded the coverage of end-to-end tests in the CI to accommodate multiple versions of the Cardano node and various hard fork scenarios.

Finally, they completed the enhanced node communications between Mithril and Cardano for retrieving UTXOs and kept working on the threat modeling and risk analysis for P2P networking.

Low level overview​

  • Completed the issue Light Wallet: Compute message to sign for CardanoTransactions #1436
  • Completed the issue Light Wallet: Implement proof generation route in the aggregator #1467
  • Completed the issue Enhance ImmutableFile list computation resilience #1450
  • Completed the issue Enhance end to end test for Cardano hard forks #1464
  • Completed the issue Add WASM client step in Mithril Client multi-platform test #1408
  • Worked on the issue P2P threat modeling and risk analysis #1350
  • Worked on the issue Create a test network on SanchoNet #1173
  • Worked on the issue Enhance Mithril/Cardano node communication #1315
  • Worked on the issue Generate automatic documentation for CLIs #1471
