Certification of Cardano stake distribution​

Update 2024/10/21

We have shipped stable support for the Cardano stake distribution certification with distributions 2437 and 2442.

A threshold of at least 70% of the stake running version 0.2.182 (within 10 days after the distribution 2442 is released) is mandatory in order to activate the certification of the Cardano stake distribution on the release-mainnet network.

The Mithril Protocol Insights dashboard displays the adoption rate of the different signer versions on the release-mainnet network.

With the release of the new distribution 2437, we have started to roll-out the certification of the Cardano stake distribution in the Mithril networks.

The Mithril network now provides certified Cardano stake distribution data without requiring a full Cardano node, a useful feature for applications such as bridges and layer 2 solutions. The key features include:

  • Certification of the Cardano stake distribution of the ending epoch at each epoch transition.
  • New HTTP routes in the Aggregator REST API to access this certified data.
  • Updates to the Mithril client library and CLI for retrieving and verifying Cardano stake distribution.
  • WASM client support for these functionalities.
  • Mithril Explorer now displays certified Cardano stake distribution.

The roll-out plan of the feature is the following:

  • Distribution 2437:
    • Activation of the certification of Cardano stake distribution in the pre-release-preview network.
    • Activation of the certification of Cardano stake distribution in the release-preprod network.
  • Distribution 2442:
    • Activation of the certification of Cardano stake distribution in the release-mainnet network.
