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 summary​

Adding support for script based committee members certificates: authorization and resignation. It is now possible to convert extended signing Drep and Committee keys to a Shelley-format key. Improvements to Conway era tests. Use threshold instead of quorum for committee members.

High-level summary​

This week, the Hydra team fixed a bug in the smoke test and refactored to allow network functions to distinguish between inbound and outbound. The team also prepared a cardano-api 8.44 branch for cardano-node 8.10 once it gets released. They also contributed to the cardano-ledger-api by undeprecating and exposing redeemerPointer.

What did the team achieve this week​

  • Fix FaucetFailedToBuildTx in smoke test #1384
  • Refactoring to allow network functions to distinguish between inbound and outbound
  • Prepared a cardano-api 8.44 branch, but got blocked 👇
  • Undeprecate redeemerPointer and expose it in cardano-ledger-api cardano-ledger#4259

What are the goals of next week​

  • Complete new /commit endpoint interface #1350
  • Refactor to allow NodeLogic to pass through connection messages, to unblock 👇
  • Use versioned handshake when connecting hydra-nodes #1010
  • Test all combinations of decrement/close/fanout for #1057
  • Meet with tech writers about the landing page
