High level overview​

This week, the Mithril team released a new one-line installer for the pre-built Mithril binaries, simplifying the update process for SPO signers. They also published an overview of the protocol security on the documentation website. The team began implementing a new type of certification for the Cardano database to enable differential updates, scaffolding a new signed entity type, and progressing on the computation of the message to sign. Additionally, they adapted the WASM client npm package to support NodeJS and started working on a cache for certificate verification in the WASM client.

Finally, the team completed the removal of legacy store adapters from the codebase and explored solutions for signer registration in networks with multiple aggregators.

High level summary​

The most notable change this period is extraction of a testing framework ImpSpec that we developed for testing Ledger implementation. This meant extracting reusable functionality, packaging into a seperate library and releasing it to Hackage.

Most of the efforts are still dedicated to improving our tests and working on conformance testing.

High level overview​

This week, the Mithril team released a new version of the Protocol Insights dashboard. They also completed implementing the new status route in the aggregator and upgraded the explorer to display its information. Additionally, the team completed the refactoring of the beacon used to snapshot the Cardano database and started working on the activation of the Pythagoras Mithril era on the pre-release-preview network.

Finally, they worked on removing the legacy store adapters in the signer and aggregator and explored solutions for signer registration when multiple aggregators are running on a Mithril network.
