Weekly development report as of 2023-03-24

Weekly development report as of 2023-03-24


Last week, the networking team released node v.1.35.6, which brings Dynamic P2P networking to mainnet. Dynamic P2P enables SPO relays to automatically connect to each other, replacing the current manual configuration process. See this blog post for more details.

The ledger team made progress on the Conway era implementation by expanding the ledger API and including multiple governance features. They also kept working on the specification and Haskell implementation, continued integrating ledger packages into cardano-node, and addressed technical debt.

The consensus team continued working on the UTXO-HD prototype refactoring and Genesis design and testing. They also extracted the fs-sim package, which provides a file-system abstraction layer that can be used for testing and simulation. This makes the consensus code base smaller while providing a package that the community can reuse and contribute to. 

Finally, they fixed a failing property test related to iterators and continued working on mempool and VRF improvements.

As always, see this technical development report for more details from different teams.


This week, the Daedalus team worked on the application’s starting screen improvements to show a more precise sync progress with decimals. 

Work is ongoing on the Lace desktop development. The team improved the DApp Connector’s browser navigation and transaction drawer logic and fixed minor UI issues to improve the overall user experience. 

Finally, they finalized and implemented a simple onboarding mechanism for the local node feature.

The Adrestia team worked on extending the multi-signature feature with delegation functionality in cardano-wallet. They also worked on extracting the transaction balancing library and did some refactoring of the DBLayer to improve performance and memory usage. 

Finally, they continued working on performance optimization of cardano-services in cardano-js-sdk.


The Marlowe team fixed the inclusion of the stake address in the Marlowe address, removed trace statements from the Marlowe validator, and assessed options for preventing double satisfaction. The team also assessed various conditions in the Marlowe semantics validator: adding a check for the positivity of accounts for the output state, guarding against duplicate accounts, guarding balance postcondition, and guarding against negative deposits in the validator. They also documented the rationale for allowing multiple outputs to an address, fixed Eq instance for ReduceWarning, added missing specification tests for validator semantics, and addressed minor issues related to the validator and its spec.

Finally, they implemented a transaction detail view for Marlowe Explorer, displayed ada amounts in a more readable way, and implemented a paginated index of all Marlowe contracts.


The Hydra team continued working on hydra-node mainnet compatibility, added a golden test suite for Hydra Plutus scripts and some detection of hydra-node misconfiguration, established a mainnet limit of 100 ada per commit (for now), and addressed smaller tasks in preparation for the mainnet beta release. 

The Mithril team continued implementing the migration of the aggregator stores to a relational design and completed the adaptation and migration of the stake pool store. They also worked on refactoring the multi-signer to enable it to sign multiple concurrent messages. Additionally, they finished implementing the automatic handling of API versions switch at era transition.

Finally, the team successfully completed the tests to create certificates and snapshots on a network running on the Cardano mainnet and fixed issues related to deadlocks on the SQLite connections. 


If you haven’t had a chance to review the updates to CIP-1694, IOG encourages you to! You can contribute directly to GitHub and continue the conversation on various community channels.

Following on from the earlier CIP-1694 workshop in Colorado, IOG would like to invite all community members to a Zoom conversation on March 30. It will be an opportunity to recap the workshop with attendees, hear more about CIP-1694, as well as discuss future workshops and the next steps towards the age of Voltaire. RSVP here if you’d like to join. 

This week in Project Catalyst, the team introduced a proposed iteration for the community assessment stage coming into Fund10. You can rewatch the segment from the main town hall here. There will be more information shared in the coming weeks, make sure to stay tuned and register your attendance for the upcoming town hall.

Also, the Special Voting Event introduced during this week’s 360 segment is coming soon. More details will be announced soon, but you can register via the usual voter registration in Catalyst to participate in the upcoming voting event.

Lastly, if you’re trying to stay up to date with everything that's happening in Project Catalyst, bookmark the past issues of the weekly newsletter. Check it out here.


ネットワーキングチームは、ダイナミックP2Pネットワーキングをメインネットにもたらすノードv. 1.35.6をリリースしました。ダイナミックP2Pを使用すると、SPOリレーが自動的に相互接続され、現在の手動設定プロセスが置き換えられます。詳しくはこちらのブログ記事をご覧ください。














Basho( スケーリング)

Hydraチームは、引き続きhydra-nodeのメインネット互換性に取り組み、Hydra Plutusスクリプトのゴールデンテストスイートとhydra-nodeの設定ミス検出を追加し、コミットごとの100ADAのメインネット制限を確立し(暫定)、メインネットベータリリースに向けて小規模なタスクに対処しました。 






今週のProject Catalystでは、Fund10に導入されるコミュニティ評価段階のイテレーション案が紹介されました。ここで、メインタウンホールからセグメントを再視聴できます。今後数週間のうちに、さらに情報が更新される予定です。今後のタウンホールへの参加登録をしてください。
