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.

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.

High level overview​

This week, the Mithril team released the new distribution 2423.0, which includes the removal of the snaphot command of the client CLI, as well as bug fixes and optimizations. They also continued implementing the certification of Cardano transactions in Mithril networks and improved the throughput of the prover route of the aggregator by fixing some bottlenecks in the Merkle proof computation. Additionally, the team made progress on low-latency certification by working on the retrieval of the transactions with the chain sync mini-protocol and Pallas, as well as the handling of rollbacks of the chain.

Finally, they kept working on the threat modeling explainer for the documentation website and provided support for multiple TLS implementations in the client library thanks to a community contribution.

High level overview​

This week, the Mithril team continued implementing the certification of Cardano transactions in Mithril networks. They improved the throughput of the prover route of the aggregator by using resource pooling and made progress on low-latency certification by transitioning to a chain point-based beacon, which allows for faster transaction signing. They also kept investigating prover performance bottlenecks, worked on fixing a bug that caused unsigned transactions to appear as signed, and continued implementing the import of transactions with the ChainSync mini-protocol and Pallas.

Additionally, the team started preparing the threat modeling explainer for the documentation website and kept investigating some Cardano node error messages that could be caused by how the Pallas client handles connections to mini-protocols.
