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.
