Status Updates (February, 2022) > February 4, 2022


This week, the team finalized Daedalus v.4.8.0 release changes, including a note for users using computers with less than 16GB of RAM and an option to enable the Runtime System (RTS) flags that optimize memory usage at the cost of increased sync time.

The team also worked on the implementation of rewards history, unspent rewards display, JS SDK development, and analytics.

Finally, they continued working on a range of user interface improvements.


This week, the team worked on finalizing a new transaction workflow by adding support for staking transactions on a transaction construction step. Also, the team is working on performance improvements and optimization of the DB layer in cardano-wallet, and designing a cardano-js-sdk MVP.


This week, the team identified and fixed an outbound governor bug and continued working on timeout tests and diffusion simulations. They wrote transformer instances for various io-classes, and prepared a pull request to update cardano-node dependencies along with several P2P fixes based on node v.1.33. Finally, the team finished an initial review of IOSimPOR - a version of the IO simulator that can detect and reverse races.


This week, the team continued working on performance optimizations and ledger enhancements. They proposed the next parameter update to increase block size by a further 8KB (72KB to 80KB). In addition, they triggered another update proposal to increase Plutus script memory units per transaction on the Cardano mainnet from the current 12.5 million to 14 million. Both changes will take effect at the boundary of epoch 319.

The team also implemented CDDL flag within cardano-ci and made a series of improvements to CLI functionality.

The Hydra team completed work on a first version of on-chain validators for the full Head life cycle with the latest pre-release 0.3.0. Also, they published the engineering roadmap for Hydra Head and a new blog post explaining the Hydra Head protocol as the first step towards the full Hydra vision.


This week, the Plutus team developed a new experimental PAB command line interface tool, which is available in the Plutus-apps repository. This tool offers developers a simpler way to get started with project creation using a pre-configured template from the terminal, rather than manually installing and configuring it. They also worked on benchmarking experiments and validations, as well as updates to their backlog and product strategy.

The Marlowe team finished their work on contract merkleization and worked on the conversion of slots to POSIX time while creating transactions. They also started scoping the features of Marlowe Market and worked on documentation.
