High level summary​

  • More anchor data hash checks were added to cardano-cli commands.
  • Support to create certificates that can register and delegate stake.
  • Moved various era agnostic commands to the top level of cardano-cli.
  • Added Cardano.Api.Tx.Compatible to cardano-api which allows the creation of simple unbalanced transactions that can submit protocol updates in any era.

Overview of [sprint 73][sprint-73]​

Ouroboros-Network-0.18 release​

We released ouroboros-network-0.18. The main features are:

  • integration with typed-protocols-0.3
  • cardano-client library doesn't depend on the non-p2p stack
  • We expose connectToWithMux family of functions in ouroboros-network which give access to the underlying [Mux handle][mux-handle].
  • Added NodeToClientV_19: to support the new GetLedgerPeerSnapshot query in local-state-query mini-protocol [ouroboros-consensus#1067].

See full [the list of PRs][ouroboros-network-0.18] included in this release. ouroboros-network-0.18 was integrated with ouroboros-consensus ([ouroboros-consensus#1223])

Tx-Submission​

We continued working on tx-submission and monitoring its performance.

Ouroboros-Network - Mithril Design​

We internally discussed how to support the [Mithril design][cip#137]. In In the near future, we will be able to socialise the report we've been working on.

Code Refactoring​

We reorganised some of our substysems to use qualified imports with simplified names:

  • [ouroboros-network#4990] (connection-manager, inbound-governor)
  • [ouroboros-network#4997] (network-mux)

We also removed deprecated APIs in [ouroboros-network#4998]sim#182]

High level summary​

We implemented the remaining improvements and fixes discovered in Conway, to be fixed during the bootstrap period: * protection against deposit loses * ensuring that DReps exist before delegating * updates to SPO vote threshold calculation * improved well-formedness check Additionally, we added two new rules: Mempool and HardFork, that will allow us to flexibly add processing logic in the future. We also dropped pointers for Conway and enhanced predicate failure reporting for pre-Conway eras.

Finally, we added more tests - both unit and conformance tests.

Low level summary​

  • pull-4647 - Drop pointers from UMap in Conway
  • pull-4642 - Mempool rule
  • pull-4553 - Address issues in auto-generated CDDL specification
  • pull-4650 - Check ppuCoinsPerUTxOBytes well-formedness
  • pull-4648 - Updated conformance to work with new MAlonzo types
  • pull-4653 - Improve color output in Imp spec
  • pull-4603 - Add more tests for voting behaviour
  • pull-4639 - Prevent non-registered return accounts for proposals' deposits and TreasuryWithdrawals
  • pull-4632 - Export Unsafe constructors for TxBody, TxBodyRaw and MemoBytes
  • pull-4654 - Add applyTxOpts to ApplyTx
  • pull-4657 - HardFork rule
  • pull-4659 - Change how SPO votes are counted
  • pull-4660 - UTXO conformance with Babbage transactions
  • pull-4652 - Ensure dreps exist prior to delegation
  • pull-4649 - Mismatch type for predicate failures
  • pull-4676 - constrained-generators: (++.) and singleton_ for lists
  • pull-4679 - Fixes for release

Mithril Team Update

High level overview​

The Mithril team continued working on decentralizing the signature orchestration of the Mithril network. They completed the implementation of the autonomous computation of the messages to be signed by the signer and worked on adapting the way some signing configuration is broadcast to the signers. They also kept working on preparing for the new Pythagoras Mithril era.

Finally, they started working on refactoring the Prometheus metrics in the signer, fixed some minor bugs, implemented some optimizations on the node logs and the aggregator REST API, and made the Cardano transaction client stable.

High level summary​

The DBSync team has fixed issues of the latest release, related to offchain data, wrong pool_stat fields, invalidated votes. We also added a requested feauture, which optionally adds a new address table, separating the address from the tx_out table. Finally we worked with the ledger team for memory improvements and introducing ledger events for DBSync.

Lower level summary​

Older missing summary​

Previously, the DBSync team prepared release 13.5.0.2 which passes the HF and brings all new governance functionality.
