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.

  • Completed the issue Aggregator/Signer preload transactions when Cardano transactions certification is not activated #1782
  • Completed the issue Explorer does not handle invalid transaction hashes #1784
  • Completed the issue Cardano transactions import blocks aggregator and signer #1797
  • Completed the issue Resource exhausted on Cardano node socket #1803

High level overview​

This week, the Mithril team continued implementing the certification of Cardano transactions in Mithril networks. They completed the low-latency certification with the retrieval of transactions using the chain sync mini-protocol and Pallas and worked on fixing some bugs occurring during the warmup phase of the signer and aggregator. They also worked on supporting the new Cardano node version 8.12 and kept redacting a draft CIP for the diffusion of Mithril signatures through the Cardano network.

Finally, the team fixed a bug that prevented the parsing of some blocks in the SanchoNet network and made some optimizations on the databases of the signer and aggregator.

  • Completed the issue Import Cardano transactions with ChainReader #1705
  • Completed the issue Cardano signatures are not produced on testing-sanchonet #1750
  • Completed the issue SQLite WAL files are not truncated in signer and aggregator #1707

High level overview​

This week, the Mithril team released the threat modeling explainer for the documentation website. They also continued implementing the certification of Cardano transactions in Mithril networks and the low-latency certification with the retrieval of transactions using the chain sync mini-protocol and Pallas. Additionally, the team started redacting a draft CIP for the diffusion of Mithril signatures through the Cardano network.

Finally, they fixed a bug that prevented the verification of the transactions included in the last certified block and improved the WASM client's documentation.

High level overview​

This week, the Mithril team continued implementing the certification of Cardano transactions in Mithril networks. They implemented a warmup strategy for the signer and aggregator to begin importing transactions as early as possible, thus minimizing the impact of network activation on certification. They also significantly improved the throughput of the prover route of the aggregator by addressing database access bottlenecks. Additionally, the team made progress on low-latency certification by completing the handling of chain rollbacks and nearly completing the retrieval of transactions using the chain sync mini-protocol and Pallas.

Finally, they made final modifications to the threat modeling explainer for the documentation website, which will be released shortly, and worked on a bug that occurs when parsing some blocks of the SanchoNet network.
