High level summary​

Ledger team continued working on conformance tests and other improvements to the ledger test suite. There was a lot of communication with community members and other core teams about the upcoming hard fork. Some of the Conway specific changes that could affect DApp developer where documented:

There was a minor bug discovered and fixed in how DRep expiration was initialized, which doesn't have any impact on the upcoming Chang hard fork, since DReps cannot affect ratification during the bootstrap phase.

High level summary​

Some minor new features have been added, namely ledger state queries that are necessary for figuring out votes for current proposals and functionality for computing the size of transaction necessary for network communication. Other than that most of the focus still continued to be on improving Conway testing coverage and addition of conformance tests.

Low level summary​

Conway​

  • pull-4514 - Add governance related state queries
  • pull-4521 - Added method to compute over-the-wire CBOR encoded transaction size

Testing​

  • pull-4518 - Made conformsToImpl discard generator failures
  • pull-4508 - Make Imp tests setup more realistic
  • pull-4496 - Enable conformance testing for RATIFY
  • pull-4544 - Updated translation of UnRegDRep deposit

Infrastructure and releasing​

  • pull-4531 - Free up disk space in the GHA CI runner before building
  • pull-4526 - cabal.project: Bump index-states and remove allow-newer
  • pull-4532 - Fix cardano-ledger-core version
  • pull-4536 - Bump plutus to 1.32.0.0
  • pull-4537 - GHA: fix cabal version mismatch between build and test job
  • pull-4540 - Free up disk space in the GHA CI runner before testing
  • pull-4545 - Update formal-ledger-specifications SRP

High level summary​

Same as with the prior report we are focusing on testing Conway features and conformance testing. One bug was discovered and fixed as a result of this testing, which would only have affected Conway functionality until after the bootstrap phase is over. We also finished fully defining Conway CDDL specification in Haskell.

Low level summary​

Conway​

  • pull-4516 - Use motionNoConfidence drep thresholds to ratify NoConfidence
  • pull-4503 - Improvements to plutus debug

Testing​

  • pull-4485 - Improvements for GOVCERT conformance test
  • pull-4495 - Update executable ledger spec
  • pull-4494 - Added minitracing over things with ExecSpecRule instances
  • pull-4440 - Implement more tests in Alonzo.Imp.UtxowSpec.Invalid
  • pull-4493 - constrained-generators: some special-case hooks for the prettyprinter
  • pull-4501 - constrained-generators: Add a callback to saturate constraints
  • pull-4483 - constrained-generators: Start on a tutorial / cheat sheet
  • pull-4437 - Test Conway CDDL using Cuddle
  • pull-4506 - Fix PParams and PParamsUpdate field order for conformance tests
  • pull-4510 - Auto-generate Conway CDDL using Cuddle

High level summary​

This period we added some last minute changes that were necessary for improving resilience and safety of Conway implementation:

  • Authorization of hot credentials for constitutional committee members is now only possible for cold credentials that are present in the ledger state, either in the current committee or in one of the proposals.
  • Voting is restricted to entities that are present in the ledger state
  • DRep votes will be removed whenever DRep unregisters
  • Pricing model for the size of reference scripts was changed from linear to exponential. Moreover, extra limits on the total size of reference scripts being used have been put in place.

  • pull-4433 - Improve resilience of future PParams
