Mithril Team Update

High level overview​

This week, the Mithril team continued implementing the certification of Cardano transactions in Mithril networks. They worked on scaling the signature and proof generation for mainnet with the compression of the transaction Merkle tree by using sub-Merkle trees of transactions by block ranges. They also made progress in designing low latency certification, investigated a memory leak in the signature/proof process, and worked on retrieving the tip of the chain with the Pallas chain observer. The team almost completed the prototype for decentralizing signer registration with the relay and a peer-to-peer (P2P) network. Additionally, they completed the refactoring of the database providers of the aggregator and re-span the testing-sanchonet network following the release of Cardano node 8.10.0-pre.

Finally, the team made some optimizations on the compilation of their pre-built binaries to fix panics occurring on CPUs without ADX instructions, and created a network configuration file on the repository to facilitate automatic compatibility checks.
