High level overview​

This week, the Mithril team released the new distribution 2428.0, which includes support for Cardano node version 9.0.0, as well as bug fixes and optimizations. They also continued implementing the certification of Cardano transactions in Mithril networks by calibrating the signature parameters for mainnet, fixing a bug preventing the signature of the last block advertised as certified, optimizing a part of the artifact production that was blocking the certification, and starting removing the code reading transactions from the immutable files.

Finally, the team started working on the certification of the Cardano stake distribution and continued redacting a CIP for the diffusion of Mithril signatures through the Cardano network.

High level overview​

This week, the Mithril team worked on supporting Cardano node version 9.0.0 and started working on a new Mithril distribution. They also continued implementing the certification of Cardano transactions in Mithril networks. They fixed some bugs blocking the REST API during transactions import, causing resource exhaustion on the aggregator Cardano node, and creating some exceptions in the explorer. They also kept redacting a draft CIP for the diffusion of Mithril signatures through the Cardano network.

Finally, the team worked on enhancing the artifact production in the aggregator to avoid blocking the certification and finalized enforcing the linting of all the files in the repository with the CI.

High-level overview of sprint 65​

Karl Knutsson (CF) fixed a bug which prevented a node using bootstrap peers to sync using them, for a more detailed description see ouroboros-network#4899.

Earlier this year we fixed bugs in IOSimPOR which prevent us from using it in ouroboros-network (io-sim#153, io-sim#159); since ouroboros-network#4872 was merged we have a large number of tests that are using IOSimPOR's schedule exploration. In the last sprint we fixed some bugs discovered by IOSimPOR in ouroboros-network:

We continued working on new tx-submission logic: ouroboros-network#3311 as well as on Genesis. The work on Genesis is split in a few PRs which are currently in review process:

High-level overview of sprint 64​

Karl Knutsson (CF) modified peer sharing behaviour to not share peers whith which connections failed, see ouroboros-network#4883 for more details.

We fixed inbound governor counters tracer, see ouroboros-network#4885.
