High level overview​

This week, the Mithril team continued implementing incremental certification of the Cardano database, focusing on feature stabilization, production readiness, testing, and optimization. They also worked on implementing a prototype 'slave' mode of the aggregator to support the signer registration across multiple aggregators. Additionally, they kept working on supporting the upcoming Cardano node v.10.2.

Finally, the team continued investigating the source of failing builds in the Hydra CI and worked on setting up code ADRs in the repository.

High level overview​

This week, the Mithril team continued implementing incremental certification of the Cardano database, focusing on feature stabilization and production readiness. They also worked on supporting the upcoming Cardano node v.10.2 and documenting the certification process for each certifiable data type.

Finally, the team completed cleaning up legacy code from the 'Thales' era and started working on a slave mode for the aggregator signer registration.

High level overview​

This week, the Mithril team released the new distribution 2506.0, which fixes a certificate chain security issue discussed in this developer blog post

The team continued implementing incremental certification of the Cardano database, completed the client library, client CLI, and monitoring, fixed bugs, and worked on unstable features. Additionally, they worked on decommissioning the testing-sanchonet Mithril network and ending support for macOS x64 pre-built binaries in the CI.

Finally, the team fixed all remaining flakiness in end-to-end tests in the CI and worked on cleaning up legacy code from the 'Thales' era.

High level overview​

This week, the Mithril team completed the activation of the ‘Pythagoras’ Mithril era on the mainnet, which has occurred as expected at the transition to Cardano epoch 539. They also created the pre-release for the new distribution 2506.0-pre.

The team continued implementing incremental certification of the Cardano database, working on the client library, client CLI, and WASM client. They also kept implementing monitoring and dashboarding. Additionally, they completed the dependency builder refactoring in the aggregator.

Finally, the team fixed some flakiness in end-to-end tests in the CI and prepared for sunsetting the SanchoNet network.

High level overview​

This week, the Mithril team created the transaction to activate the switch to the next ‘Pythagoras’ Mithril era, which will occur at the transition to Cardano epoch 539. They also started communicating the upcoming bump in the minimum version of glibc required to run Mithril pre-built binaries on Linux.

The team continued implementing incremental certification of the Cardano database, working on the client library, client CLI, and WASM client. They also began implementing monitoring and dashboarding. Additionally, they started refactoring the ‘mithril-common’ library and simplifying the dependency builder in the aggregator.

Finally, the team worked on dropping support for pre-built binaries for macOS x64 architecture and attempted to fix some flakiness in end-to-end tests in the CI.
