High level summary​

Broadly speaking the Ledger team focused on a few main areas of Conway era:

  • Creation of voting state snapshots in order to correctly delay ratification for one epoch
  • Validation of the Governance Actions sequencing and ordering
  • Proper expiry of DReps and Proposal Procedures
  • Expanding Conway Genesis functionality
  • Utilization of some of the new Protocol Parameters in ledger validation rules

High level summary​

The ledger team made great progress in advancing Conway era forward. In particular, voting for DRep and Stake Pool Operators is now at the state that can be used by downstream components. Addition of new ledger state queries makes it possible to verify changes to the governance state, such as placement of votes, submission of governance proposals, inspecting DRep stake distribution and more. Addition of treasury withdrawals concludes the ability to enact all of the governance actions, except for the hard fork initiation.

High level summary​

The ledger team was working almost exclusively on the Conway era implementation. In particular, the main focus was directed towards solidifying transaction related types and their binary representation. We also directed some effort into unblocking Plutus team with respect to PlutusV3 integration.

High level summary​

Our focus was on planning and implementing Conway features that we would like to see deployed and running on Sanchonet. All members of the ledger team participated in the CIP-1694 workshop and had an in-person meeting, where we discussed plans forward for the Conway era. We also investigated some transaction validation issues that occurred on preview with the latest node (for 8.2 release). Additionally, we did some preparatory work that will help us define the types we need for Plutus V3 and integrate with the new version when it will become available. We also made progress on the constraint-based generators, which can now generate valid transactions and ledger states.

What we achieved​

  • [pull-3521] [pull-3554] Improved Governance model (GovernanceProcedures, ProposalProcedure)
  • [pull-3520] Improved Governance-related naming (Renamed Tally to Gov and VDel to GovCert )
  • [pull-3531] Refactored and simplified code interacting with Plutus
  • [pull-3558] Fixed a bug that was breaking validation on preview, related to refernce inputs witnesses. We backported and released the fix.
  • [pull-3550] For Conway to run on Sanchonet, we updated the era Translation to remove zero-ADA outputs. This was necessary because such outputs exist on mainnet, but in Conway they are not allowed.
  • [pull-3551] [pull-3546] [pull-3472] Updated tools and added some small improvements
  • [issue-3146] [pull-3498] Introduced Conway protocol parameters
  • [issue-2948] [pull-3499] Implemented ConwayGenesis with the new protocol parameters

High level summary​

The ledger team made progress on the conway ledger era. In particular, the design and implementation of the new certificates is near complete, we refactored some of our data structures to be able to support DReps, we cleaned up the serialization format, and renamed things to make clearer the differences with Shelley.

The team also completed integration work for the next node release, namely 8.1.0. And, as always, we continue to address technical debt.
