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.

High level overview​

This week, most of the Mithril team attended the Cardano Buidler Fest #1 in Toulouse, France. They also continued implementing the certification of Cardano transactions in Mithril networks and worked on scaling the signature and proof generation for mainnet by compressing the transaction Merkle tree using sub-Merkle trees based on transaction block ranges. The team identified the source of an issue preventing proper memory release during the signing/proving of a large set of transactions and developed a fix for it. Additionally, they completed the prototype for decentralizing signer registration with the relay and a peer-to-peer (P2P) network.

Finally, the team implemented a configurable feature for test networks to log unparsable blocks instead of panicking and investigated some unexpected error logs occurring on the Cardano node when the signer and aggregator connect to the mini-protocols.

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.

High level overview​

This week, the Mithril team continued implementing the certification of Cardano transactions in Mithril networks. They focused on scaling the signature and proof generation for mainnet, completed the incremental storage of transactions, activated the signature of the transactions on the testing-preview network, and prepared a new network to test the scaling on mainnet data. The team also made progress on a prototype for decentralizing signer registration with the relay and a peer-to-peer (P2P) network. Additionally, they worked on refactoring the database providers of the aggregator.

Finally, the team delivered a community requested feature that displays the minimum versions of the Cardano node that the signer supports in a machine-readable format. They also provided a manual setup guide for the relay in the SPO user guide.
