Weekly development report as of 2022-05-06


This week, the node (ledger, consensus, node API & CLI) and Plutus teams continued preparing for June’s Vasil hard fork. The upcoming pipelining upgrade is undergoing benchmarking before being merged into master.

The DevOps team worked on a Genesis generator that creates Byron and Shelley files with the same parameters. They also improved the cardano-world repository, enhancing endpoints and OCI images for node, submit-api, wallet, and db-sync. Finally, the team performed materialization of the Cardano node Nix build, which speeds up the evaluation time.

The networking team continued working on diffusion tests, typed-protocols refactorization, and resolved some test suite performance issues. They are now in the process of enabling dynamic block production and re-deploying eight nodes on the testnet to enable 50 new SPOs to join the testnet for evaluation and feedback purposes.


This week, the Daedalus team started running regression tests for the upcoming Daedalus v.4.10.0 and made compatibility adjustments for the new cardano-wallet API. The team made progress in creating the base boilerplate for the new desktop-wallet, which allows reusing most of the existing UI components from the light-wallet-browser-extension.


This week, the Plutus team updated the release, branching, and dependency management policy of plutus-apps in the README file. They also worked on new tools, created the foundation for the Conformance test suite, and completed a range of bug fixes. 

The Marlowe team modified the Marlowe Playground to pass Marlowe contracts in JSON format from the Haskell editor to PureScript, and fixed developer environments for Mac and Windows users. They also rewrote the follower contract without using arbitrary timeouts, updated the Playground to make contract nicknames editable, and fixed an issue when showing multiple choices with the same name.

Additionally, they opened the registration for the new Marlowe Pioneers training course and are managing incoming sign-ups. 


This week, the Hydra team finalized implementing the usage of ‘proper’ ed25519 signatures and are currently preparing a 0.5.0 release. The team cooperated with IOG research on aligning the ways of Coordinated Head protocol audit. Finally, they updated dependencies in preparation for updating to PlutusV2 and evaluating CIP-42 (serializeData).


This week, voting finished on Project Catalyst’s Fund8. Vote tallying is underway to reveal successful projects. Every three months, Project Catalyst produces a fresh pipeline of technical, business, creative, and community-focused projects - funded to deliver their proposed ideas that have been voted for by the Cardano Catalyst community. Fund9 opens in early June. As always, proposers are invited to submit their proposals again.

Also, startups building on Cardano can now fill out an application for the FT x Cardano Blockchain Challenge by May 31, 2022. This will allow to:

  • Be part of a 3-day bootcamp with 1-1 mentorship sessions

  • Get to know the Cardano community better

  • Get access to Seedstars network of mentors and investors

  • Get short-track to Seedstars International Ventures Fund

  • Receive tech perks

  • Get a visibility package from FT Talent by Financial Times

Daedalusチームは、予定されているDaedalus v.4.10.0の回帰テストを始め、新しいcardano-wallet APIの互換調整を行いました。また、主にlight-wallet-browser-extensionの既存UIコンポーネントを再利用するかたちで、新しいデスクトップウォレットのベースボイラー版の作成を進めました。



MarloweチームはJSON形式のMarloweコントラクトをHaskellエディターからPureScriptにパスできるようMarlowe Playgroundを変更し、MacとWindowsユーザー向けに開発者環境を修正しました。任意のタイムアウトを使用せずにフォロワーコントラクトを書き換え、コントラクトニックネームを編集できるようにPlaygroundを更新し、同名で複数の選択肢を表示したときの不具合を修正しました。


Basho( スケーリング)

Hydraチームは適切なed25519署名の使用法を実装し、現在0.5.0リリースの準備をしています。Coordinated Headプロトコル監査の方法を調整するためのIOGの研究に協力しました。PlutusV2への更新とCIP-42(serializeData)に備えて依存関係を更新しました。


Project Catalyst Fund8の投票が終わり、現在集計を進めています。Project Catalystは3か月ごとに、技術、ビジネス、クリエイティブ、コミュニティに焦点を当てたプロジェクトの新しいパイプラインを作り、Cardano Catalystコミュニティが投票した提案を実現するために資金提供します。Fund9は6月初頭に始まります。通常通り、提案者は提案を再提出することができます。
