High level summary​

This period we continued with tackling tech debt, implementing improvements that are necessary for the next Dijkstra era and we prepared the Dijkstra era for proper integration into all other components. Besides this we made various improvements to the constrained-generation library and prepared it for an initial release.

High level overview​

This week, the Mithril team completed the certificate chain synchronization in the follower aggregator. They also continued implementing the mock DMQ node to support end-to-end testing of decentralized signature diffusion. Additionally, the team worked on enhancing the 'verify' command on the client CLI to provide a detailed list of invalid or missing immutable files and kept preparing for the upgrade to Cardano node v.10.5 and the upcoming Mithril distribution.

Finally, they worked on refactoring the 'CardanoNetwork' entity, enhancing the maintainability of the new website, and made progress refactoring the STM cryptographic library.

Low level overview​

• Worked on the issue Enhance STM library readability #2568
• Worked on the issue Implement a fake DMQ node with Mithril relay #2627
• Worked on the issue Upgrade to Cardano 10.5 #2623
• Worked on the issue List the invalid/missing immutable files in the verify command in client CLI #2618
• Worked on the issue Future-proof maintainability for the new website #2622

High-level summary​

• Introduced a mempool optimization (#1565).
• Fixed a bug in the Byron deserialization of Ledger Tables (#1577).
• Added the Node-to-Node CDDL specifications (#1571).
• Work has started to extend the Haskell simulator to support adding individual transactions.
• Added support for taking ledger snapshots at predictable times (#1575).

High-level summary​

The team have been highly focused on work supporting the glacier drop; in particular fixing a bug related to replaying a large statefile, and preparing a release that includes that fix (0.22.2). We continue work to improve some observed issues with our resiliance to restarts during processing high volumes of transactions.

What did the team achieve?​

• Released version 0.22.2
• Marked release version 0.22.1 as deprecated; do not use, it contains a simple bug that prevents --network <...> from working correctly.
• Resolved bug with node getting into deadlock while restarting #2089
• Show a list off "Offline" peers in the TUI #2044
• Set the content-type for the API server responses #2094
• Small fix to the documentation #2095
• Continued to support the glacier drop

What's next?​

• Focus on improving crash-resiliance #2109
• Add HTTP endpoint for submitting transaction #2107
• Continue to focus on supporting the glacier drop

High level overview​

This week, the Mithril team continued implementing the mock DMQ node to support end-to-end testing of decentralized signature diffusion and worked on certificate chain synchronization in the follower aggregator. They also completed era transition support in the clients, enabled Linux ARM binary support in the CI, and began preparing for the upgrade to Cardano node v.10.5.

Finally, they upgraded the repository to the Rust 2024 edition and made progress refactoring the STM cryptographic library.
