Status Updates

DAEDALUS　

This week, the team resumed working on the Electron upgrade, maintaining the application window size and its position after the Daedalus relaunch. They investigated issues related to the detailed earned rewards history feature, and finalized the implementation of a warning notification when making transactions with not enough funds to redeem rewards or move native tokens in the wallet.

ADRESTIA

This week, the team made good progress in Alonzo/Plutus-related changes.

Specifically, they released GraphQL v5.0, Rosetta v1.3.0, and Explorer-app v1.6.0. The team is also preparing to release a wallet update to enable compatibility with Alonzo Node 1.28, and they are working on streamlining cardano-wallet transaction APIs to enable Plutus Application Backend (PAB) integration.

Finally, they are working on several changes required for smart contracts (collateral, script witnesses, etc.)

NETWORKING

This week, the team worked on property tests and adjusted the ConnectionManager test, which resulted in the discovery and resolution of some issues.

The team also restructured the P2P to non-P2P switch for better clarity and easier maintenance of the data diffusion API. The data diffusion module now works in an abstract monad that allows building simulations in io-sim.

DEVOPS　

This week, the team updated the Explorer-app to v1.6.0 and continued preparing for Alonzo White v1.3.

CARDANO DECENTRALIZATION

This week, the team worked on Alonzo block time budgeting calibration benchmarking. They discussed and implemented the calibration data export format, extended the block propagation analysis to perform final data validation, and delivered the final 64kb block size results.

Work is ongoing on Alonzo Plutus payload benchmarking; the team integrated the script-based transaction generator into the workbench and continued implementing the initial Plutus capacity transaction generator.

Finally, the team completed work on the trace-dispatcher and cardano-tracer components’ features, and continued testing and updating documentation.

GOGUEN

This week, the Plutus team added rollback support, updated protocol parameters in the plutus-use-cases-scripts, and made more changes that allow running scripts during the Hydra process. They also provided more documentation for the Plutus Application Backend (PAB), and steps in the README for a Cabal update.

The Marlowe team worked on a new implementation of the Balance tab within the Marlowe Run client, worked on some adjustments to the ACTUS test framework, and made updates to the timezone and timeout features. These ensure that the displayed time is offset with the browser, and the contract timeout is applied correctly, rather than using the current slot at the moment of calculation.

ADRESTIA

This week, the team's focus remained on Alonzo/Plutus-related changes.

Specifically, the team worked on streamlining cardano-wallet transaction APIs to enable integration with the Plutus Application Backend (PAB), and they are also working on updating the cardano-wallet to the Alonzo Node v1.28 with changes required for smart contracts (collateral, script witnesses, etc.)

They also identified the technical team structure for Voltaire development, worked on documentation, and continued working on the Obsidian update mechanism.

GOGUEN

This week, the Plutus team updated some hosted PAB information and fixed the type parameter name in the PAB contract. They also resolved Playground decoding errors for datums and redeemers, deleted the obsolete servant-server dependency from the plutus-contract, and updated protocol parameters in plutus-use-cases-scripts, which allows exporting some of the partial transactions. The team also generated ACTUS examples for Plutus performance and investigated ActusLabs issues in the Playground.

The Marlowe team continued working on the Marlowe Run infrastructure redesign, which includes contract setup, contract cards, and tooltips. They added a hint widget to Marlowe Run, reinstated slot parameters in the example contracts, and added default values making them read-only. The team also added a TimeFormat to the NumberFormat type, which interprets values as seconds, and displays them as minutes. They fixed some minor Marlowe Playground Client issues and implemented the new design of the contacts sidebar.

Finally, they added the "copy to clipboard" functionality for wallet IDs and tidied up role inputs for contract template setup, restyling inputs to match new designs.

DAEDALUS

DEVOPS　

This week, the team were busy preparing for the Alonzo White launch. On July 14, the teams successfully forked the Alonzo testnet to the new Alonzo White node. The new network is now producing blocks, and besides the core SPO group, Project Catalyst members and more Plutus partners have joined Alonzo White testnet activities. Meanwhile, IOG quality assurance and other teams continue working on the feature testing.

ERC20 CONVERTER

This week, the team continued working on Cardano to Ethereum token migration within the converter. They investigated different development scenarios and found related solutions to also improve the Ethereum to Cardano migration process. This influenced the decision to deploy all improvements within one release without separating overall functionality. Therefore, the ERC20 converter testnet will require several further weeks of development but will be deployed featuring a greater number of updates and functional features. This will not influence the mainnet release, which is planned for deployment around the dates of the Alonzo mainnet hard fork.

CARDANO DECENTRALIZATION

This week, the team worked on the Merkle trees design documentation, finalized Marlowe Run redesign based on user testing results, and continued working on the Marlowe Run infrastructure improvements. They validated the LAM contract against the ACTUS test suite and investigated ActusLabs issues in the Playground, also generating ACTUS examples for Plutus testing.

The team implemented a feature that allows the state machine to produce thread tokens, fixed a handshake connection issue to the Alonzo node, and also changed the time resolution property in Plutus to enable the use of milliseconds.

More work has been done within the Plutus Application Backend (PAB) development. The team worked on PAB documentation, enabled optional permissive CORS policy, and also enhanced chain index operations. Along with that, they produced an example application that waits for a blockchain event, and continued PAB to Alonzo synchronization process.

Finally, the team prepared for the ‘Hosted PAB’ workflow, which will enable the use of textual links with partial transactions, and started working on contract API UX improvements.
