Weekly development report as of 2023-06-09


This week, the core technology teams continued working on node, networking, consensus, and ledger components.

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


This week, the Lace team continued working on multi-delegation scope, completing work on stake distribution reporting and a new input selection algorithm for partitioning UTXOs according to user staking preferences in cardano-js-sdk. They also continued working on UI components for a new staking page in the Lace browser, implementing Brave support, and finalizing work for the upcoming release of Lace v.1.2.

Make sure to read a new blog post about how Lace incorporates Web3's principles of collaboration, full transparency, and a decentralized ecosystem into an open source light wallet platform.

The Adrestia team focused on enhancing the DB layer and separating the balance tx library. They continued progressing with multi-signature wallet delegation and updating the cardano-wallet to support node v.8.0.x. Finally, they completed work on the MBO repo.


This week, the Plutus tools team worked on finalizing the Marconi EpochSDD and MintBurn indexer, designing the resuming strategy for Marconi indexers running in parallel, and separating the mocked node from the Plutus PAB.

The Plutus core team merged the PR that adds BLS12-381 primitives to Plutus Core as well as the formalization. This includes 17 built-in functions added to Plutus Core, which will be made available after the Conway hard fork.

The Marlowe team added some new options to the Marlowe Runtime CLI and a query for Merkle tree inputs for a contract. They also explored the use of web plugins in end-to-end automated testing and automated a range of test scenarios. The team fixed some JSON download errors, and options for marlowe-proxy along with broken links in the Marlowe Playground. 

Finally, they published the document versioning policy for Marlowe.


This week, the Hydra team focused on finding solutions to various problems, including the investigation of issues with a head on mainnet, monthly report publications on the website, and implementing ‘Option A’ for commits from external wallets. While most of these items are still being worked on, significant progress has been made. To expedite the investigation, the team improved their logging to provide more precise errors when a transition requirement fails and to reduce duplication in logged content. 

Finally, the team is exploring formal methods and attended a workshop on formalizing cryptographic protocols in Agda.

This week, the Mithril team worked on implementing a new sub-command for restoring Mithril stake distribution in the client. They also refactored the dependency injection of the client, worked on infrastructure enhancements for the Mithril network, and completed the performance tests of the new stake distribution computation on mainnet.

Finally, the team fixed some failures in the CI following the upgrade to Rust v.1.70.0, and investigated a bug on the aggregator state machine.


This week in Voltaire, conversations continue on CIP-1694 to establish an initial Minimum Viable Governance (MVG) framework. This framework is crucial for the advancement of participatory governance within the Cardano ecosystem. By collecting feedback from community members, diverse viewpoints can be incorporated to ensure the governance system aligns with the community’s needs and desires. 

The following workshops, hosted this week, yielded some valuable feedback:

  • Zug, Switzerland by the Cardano Foundation

  • Worcester, Massachusetts U.S. by jamesdunseith#3315

  • Virtual by Seo4u#6254 

  • Fukuoka, Japan  by Yuta#6370 (Jun 10)

  • Chicago, Illinois U.S. by NeoCornelius#2319 (Jun 10)

  • Prague, Czech Republic by mmahut#8044 (Jun 10)

Check out workshops happening near you and join the conversations.

CIP-30 and CIP-95 are mechanisms proposed in Cardano Improvement Proposals (CIPs) to empower ada holders with voting capabilities. These proposals, once implemented by wallet providers, will enable community members to express their democratic consent for governance actions.

It's essential for community members to actively participate in providing feedback for CIP-1694 and CIP-95. By voicing opinions and suggestions, you can help shape the future of governance within Cardano. This collaborative approach ensures that the governance mechanisms implemented best represent the community's needs.  


During this week’s town hall the Catalyst team provided an in-depth analysis of the progress made during the extended Fund9 cooldown. They also highlighted some exciting new updates to anticipate in Fund10. Be sure to stay tuned and register your attendance for the upcoming town hall.

The team also published a Fund10 blog post announcing the relaunch of Project Catalyst hot on the heels of its 500th completed project! This blog post explains the vision, mission, and values of Project Catalyst and the new features and improvements introduced in Fund10. 

Some of these features include:

  • Milestone-based funding module - UI and workflow for transparency and security

  • The continuous testnet - enabling a running fund to test new iterations of Project Catalyst

  • A new challenge-setting process that allows the community to propose and vote for each fund's most relevant and impactful challenges

  • A new process that simplifies and streamlines the steps for creating and submitting a proposal

  • Voting app improvements that enable secure and convenient voting on mobile devices

  • A new feedback mechanism that allows proposers and voters to communicate and collaborate more effectively

  • A new governance framework that defines the roles and responsibilities of different stakeholders in Project Catalyst.

Watch out for more information on how you can participate, which will be shared in the coming days!

This week, the Education team focused on the delivery of the Cardano Days workshops at the University of Celaya, Mexico, scheduled for next week. Several members of the team will present these workshops to showcase Cardano, with a mix of in-person and remote delivery.

The team is also continuing with updates to the Haskell Bootcamp and Mastering Cardano. Preparations are being made for an in-person Haskell course later this summer, as well as their participation in the EMURGO hackathon in July.





Laceチームはマルチ委任のスコープへの取り組みを続け、ステーク分布レポートと、cardano-js-sdkのユーザーステーキング設定に従ってUTXOを分割する新しいインプット選択アルゴリズムを完了しました。Laceブラウザーの新しいステーキングページ用UIコンポーネントへの取り組みを続け、Braveサポートを実装し、来るLace v.1.2リリースの準備を終えました。


Adrestiaチームは、DB層の強化とbalance txライブラリーの分離に重点を置きました。マルチシグウォレット委任の作業を続け、cardano-walletをノードv.8.0.xをサポートするよう更新しました。MBOリポジトリの作業は完了しました。


Plutusツールチームは、Marconi EpochSDDとMintBurnインデクサーの仕上げ、並行して実行されるMarconiインデクサーの再開戦略の設計、Plutus PABからのモックノードの分離に取り組みました。

Plutus Coreチームは、BLS12-381プリミティブをPlutus Coreに追加するPRと形式化をマージしました。これには、Plutus Coreに追加された17の組み込み関数が含まれますが、これはConwayハードフォーク後に利用可能になります。

Marloweチームは、Marlowe Runtime CLIに新オプションと、コントラクトのマークルツリーインプットのクエリを追加しました。エンドツーエンドの自動化テストにウェブプラグインを使用し、さまざまなテストシナリオを自動化しました。JSONダウンロードとmarlowe-proxyのオプションに関するエラー、Marlowe Playgroundのリンク切れを修正しました。 


Basho( スケーリング)

Hydraチームは、メインネットのヘッドに関する不具合の調査、ウェブサイトへの月次報告書の公開、外部ウォレットからのコミット用であるOption Aの実装など、さまざまな問題の解決策を見つけることに注力しました。これらの案件のほとんどがいまだ取り組み中ですが、大きく前進しています。調査の迅速化を目指し、移行要件が失敗した際により正確なエラー情報を提供しログに記録されたコンテンツの重複を減らすために、ログを改良しました。 



Rust v.1.70.0へのアップグレード後のCIの障害を修正し、アグリゲーターステートマシンのバグを調査しました。
