GOGUEN

This week, the Plutus team released the Alonzo protocol upgrade, which brings exciting and highly anticipated capabilities through the integration of Plutus scripts onto Cardano. Scripts facilitate the implementation of smart contracts on Cardano and enable a range of new use cases for decentralized applications (DApps) for the very first time.

This included some fixes, supporting documentation, performance improvements, and a clean-up of the node client.

The Marlowe team worked on some documentation updates to the tutorials. They also fixed the Zero Coupon Bond contract issue, validated annuity (ANN) results, refactored ACTUS implementation, and started working on the LAX contract. Finally, they resolved several issues that occurred when connecting the Marlowe Run demo to the Plutus Application Backend (PAB).

DAEDALUS　

This week, the team focused on fixing hardware wallet issues in preparation for the Alonzo-ready Daedalus release.

ADRESTIA

This week, the team resolved an issue that occurred when submitting a transaction in Daedalus using a hardware wallet. An update for cardano-wallet including this fix has been released. They also released an update for the metadata tools to support Plutus scripts.

Finally, the team is now working on changes required for smart contracts and PAB integration.

NETWORKING

This week, the team made progress in testing the connection pruning. They also fixed several network issues within the simulation environment and expanded trace validation of inbound governor tests. The team is now preparing to rebase the P2P branch on top of master before the Alonzo mainnet hard fork.

DEVOPS　

This week, the team submitted the Alonzo hard fork update proposal, which will take effect at 21:44:51 UTC on September 12th, bringing Alonzo to mainnet.

The team also resumed working on flakes for the GraphQL stack, integrated newly released ERC20 converter versions, and continued some other infrastructure provisioning.

CARDANO DECENTRALIZATION

This week, the team worked on Alonzo benchmarking activities. They delivered benchmarks for node v.1.29, which proved no significant performance regression since node v.1.27. In addition, hard fork simulations showed no resource usage regressions. The team discussed relevant Plutus workload activities.

The team also enhanced trace generator performance, found a UTXO missing witness issue that is now being resolved, and also made some internal cleanups.

The team progressed on the node logging infrastructure rewrite and started the trace-dispatcher review and testing. They tested multi-threaded traces and runtime reconfiguration, refactored and simplified the Cardano tracer based on review suggestions, and started implementing the initialization case for trace-forward queue management.

Work is ongoing within the RTView, which the team started porting to the Cardano tracer.

Finally, they began working on the analysis improvements within the benchmarking infrastructure to enhance block boundary resource usage statistics in Marlowe Run and connection to the PAB.

GOGUEN

This week, the Plutus team resolved some synchronization problems and updated the chain index with more enhancements. They also analyzed the costing and sizing of Plutus scripts and made some general performance improvements. Finally, they updated the Plutus documentation and tutorials.

The Marlowe team continued working on annuity (ANN) implementation, validated negative amortizer (NAM) properties, and made some refactorings. They also reviewed Marlowe documentation, recorded videos for the Marlowe website, and automated some staging deployments. Finally, the team set up analytics for the Marlowe Run website.

Finally, the team continued working on the custom browser protocol implementation.

ADRESTIA

This week, the team released the Adrestia components (cardano-wallet, GraphQL, Rosetta API, cardano-explorer-app) ready for the Alonzo hard fork on the testnet. They also updated and tested the metadata tools to support Plutus scripts minting native tokens, and added Catalyst voting support to cardano-rosetta.

The team is now working on changes required for smart contracts, including collaterals, the coin selection update, fee calculation, etc., and are also implementing some fixes and optimizations.

NETWORKING

This week, the team resolved different issues related to the acceptance of existing network connections, enhanced connectivity with the node, and investigated a ‘query tip’ bug found in Alonzo.

DEVOPS

This week, the team deployed the Alonzo testnet upgrade to the ledger and were busy preparing for the mainnet hard fork. They also updated the ERC20 converter to work with the node v.1.29.0 and the latest version of the wallet. Finally, they worked on ipxed to serve NixOS images on the network.

ERC20 CONVERTER

This week, the team completed the final testing of the internal ERC20 converter. They tested it against the latest node deployed after the Alonzo testnet hard fork this week. The team has now provided the code to SingularityNET for final assessments and production readiness in their environment prior to testnet deployment. Stay tuned for more announcements coming soon.
