Weekly development report as of 2023-02-10


This week, IOG teams together with CF and Emurgo continued preparing for the upcoming Valentine (SECP) upgrade. The SECP update proposal to upgrade the Cardano pre-production environment and mainnet were submitted this week. The upgrade will take effect on pre-production on Saturday, February 11, 2023 at 00:00 UTC, and will be available on mainnet on February 14, 2023 at 21:44:00 UTC.

This week, the teams also released GraphQL v.8.0.0, which is compatible with node versions 1.35.4 and 1.35.5. For the latest progress, track this upgrade readiness page and see the compatibility matrix to stay up to date with the latest releases.

Over the past two weeks, the ledger team worked on integration efforts, cleaning up and debugging some serialization issues, and adding tests. They also continued working on ongoing large projects and released a CIP to make the ledger a registered CIP category.

The consensus team continued refactoring the UTXO-HD prototype and created a new repository that contains the anti-diff packages used in the prototype. Work is ongoing on Genesis development. The team is preparing for the meeting with researchers to audit the implementation design and continue working on basic tests and simplifications. Finally, they introduced two new tools, one for dumping CBOR-encoded blocks to JSON, and another to serve a local immutable database.

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


This week, the team continued working on Lace desktop development. They ran more automated tests, integrated Matomo analytics tracking, and worked on the reflection of the cardano-node status in the UI. They also restructured the code base so that source code files are split by feature, and separated translation files from the Lace browser folder. The team worked with the DevX team to create a single Lace desktop installer capable of connecting to all available networks (mainnet/pre-production/preview). 

Finally, they polished the inner DApp browser by adding styles and details from the UI/UX team.

The Adrestia team released Cardano GraphQL v.8.0.0 and continued preparing cardano-js-sdk for release to production. They're also working on extending the multi-signature feature with delegation functionality in cardano-wallet, and on DBLayer refactoring to improve performance and memory usage.


This week, the Plutus team continued working on the Plutus debugger, script capacity increase, and source code built-in documentation. Work is also ongoing on building indexers and addressing technical debt. 

This week, the Marlowe team improved the data hash in the chain index and worked on the Marlowe Explorer project and contract view. They also ran some unit tests for Marlowe transactions, refactored common web page creation functions, and made spec tests reproducible. 

Finally, the team set up an infrastructure for web API testing, paginated query API for loading contract headers, and added a MarloweHeaderSync protocol to marlowe-sync.


The Hydra team completed work on the Hydra V1 specification by updating graphs and adding a section about rollbacks. They further plan to make the specification more approachable and an open standard. The team also improved the hydra-cluster tool to launch a local --devnet sandbox environment and continued aligning hydra-plutus scripts with the specification by running more checks on close and contest transactions.

The Mithril team worked on the new relational design of the aggregator store, which will be used with the implementation of the version deployment monitoring for the signer nodes. They also completed the implementation of the era reader trait that powers the era switch behavior. The team finalized the development of the era reader adapter that retrieves era activation markers from transactions on the Cardano chain.

Finally, they created new SPO nodes on the Mithril networks and upgraded the Cardano node to version 1.35.5 on their devnet and infrastructure.

The sidechains team released the proof of concept EVM sidechain testnet. Developers can now test token transfer between the test environments, connect wallets, and deploy smart contracts and DApps. You can find updated documentation on how to work with the example EVM sidechain here.


This week Project Catalyst received its 400th project close-out report, which is an amazing milestone for a grassroots innovation fund in two years. Stay tuned for further updates and see the Project Catalyst website for more information.



ノードバージョン1.35.4と1.35.5対応のGraphQL v.8.0.0もリリースしました。最新の進捗状況は、アップグレード準備の進捗情報ページを、また、最新リリース情報は互換性マトリックスをチェックしてください。







Adrestiaチームは、Cardano GraphQL v.8.0.0をリリースし、cardano-js-sdkを本番環境にリリースする準備を継続しました。cardano-walletのマルチシグ機能を委任機能で拡張し、パフォーマンスとメモリー使用量を改善するためにDBLayerのリファクタリングに取り組みました。



Marloweチームは、チェーンインデックスのデータハッシュを改良し、Marlowe Explorerのプロジェクトおよびコントラクト表示に取り組みました。Marloweトランザクションのユニットテストを実行し、共通のウェブページ作成機能をリファクタリングし、仕様テストを再現可能にしました。 


Basho( スケーリング)

Hydraチームは、グラフを更新し、ロールバックに関するセクションを追加して、Hydra V1の仕様に関する作業を完了しました。 さらに、仕様をより親しみやすく、オープンな標準にすることを計画しています。ローカルのDevNetサンドボックス環境に展開するようhydra-clusterツールを改良し、closeおよびcontestトランザクションのチェックをさらに実行することによってhydra-plutusスクリプトと仕様をすり合わせる作業を継続しました。





Project Catalystは、400番目のプロジェクト完了報告書を受け取りました。これは2年間のグラスルートイノベーションファンドにとって驚くべきマイルストンです。最新情報をお楽しみに。また、Project Catalystのウェブサイトで詳細情報をご覧ください。
