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.

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.

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 implementation of a more versatile beaconing mechanism, worked on implementing incremental storage of transactions, and fixed the bug in the block parser that prevented some Conway transactions from being signed. Additionally, they continued working on a prototype to decentralize signer registration with the relay and a peer-to-peer (P2P) network.

Finally, they enhanced the internal storage of data on the test aggregator server and addressed a source of flakiness in the CI end-to-end test.

High level overview​

This week, the Mithril team released a new Mithril distribution 2412.0. This release includes several critical updates and enhancements, such as support for the Prometheus metrics endpoint in signer, deprecation of the snapshot command in the client CLI, full Pallas-based implementation of the chain observer, and support for Cardano node v.8.9.0.

The team continued implementing the certification of Cardano transactions in Mithril networks. They focused on scaling the signature and proof generation for mainnet, kept implementing a more versatile beaconing mechanism, reducing the latency of transactions signature, and continued investigating a bug in the block parser that prevents some Conway transactions from being signed. Additionally, they started working on a prototype to decentralize signer registration with the relay and a peer-to-peer (P2P) network.

Finally, the team completed the implementation of some community-requested features to verify the output folder structure made by the client, and kept investigating a source of flakiness in the CI end-to-end test.
