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.

High level overview​

This week, the Mithril team released a new Mithril protocol insights dashboard and a new explorer page displaying active and deregistered SPOs for the latest Cardano epochs. They also continued implementing the certification of Cardano transactions in Mithril networks by improving the throughput of the prover route of the aggregator and making progress on low-latency certification by completing the implementation of a chain block reader from the Cardano mini-protocol with Pallas.

Additionally, the team started working on a new beacon for signing Cardano transactions based on the chain point. Finally, they refactored the persistence library, enhanced their testing tools for Cardano transactions, and fixed a block parsing problem that prevented the signature of Cardano transactions in the test networks.

High level overview​

This week, the Mithril team continued implementing the certification of Cardano transactions in Mithril networks. They worked on scaling proof generation for mainnet by prototyping optimizations and benchmarking performance improvements. They also made progress on low-latency certification by completing the retrieval of the chain tip and importing transactions from the Cardano mini-protocol with Pallas. Additionally, they worked on a new explorer page to display in/out SPOs for the latest Cardano epochs.

Finally, the team upgraded the testing-sanchonet network following the SanchoNet network respin, created a module for building test transactions, and began removing the deprecated snapshot command from the client CLI.

High level overview​

This week, the Mithril team released the new distribution 2418.1, which includes broader CPU support for pre-built binaries and a new memory allocator for the signer and aggregator nodes aimed at preventing memory fragmentation. They also continued implementing the certification of Cardano transactions in Mithril networks and worked on scaling the signature and proof generation for mainnet. Specifically, they completed the implementation of compressing the transaction Merkle tree using sub-Merkle trees based on transaction block ranges and initiated testing and assessing performance on mainnet in a test Mithril network. Additionally, they started working on minimizing the extra disk space requirements for the signer on the SPO infrastructure.

Finally, the team implemented some optimizations for the aggregator, fixed some bugs on the client, and introduced new documentation for compiling the Mithril relay from source.

High level overview​

This week, the Mithril team prepared a new pre-release distribution 2418.1-pre, which includes broader CPU support for pre-built binaries and a new memory allocator for the signer and aggregator nodes to prevent memory fragmentation. They also continued implementing the certification of Cardano transactions in Mithril networks and worked on scaling the signature and proof generation for mainnet by leveraging the compression of the transaction Merkle tree using sub-Merkle trees based on transaction block ranges during signature and proving. Additionally, they implemented a stream mechanism for importing transactions into the signer and aggregator stores.

Finally, the team started implementing a global Mithril networks configuration file and continued investigating some unexpected error logs occurring on the Cardano node when the signer and aggregator connect to the mini-protocols.
