High-level Summary​

This week the team shipped hydra-node 2.1.0 - a significant release that brings improved deposit security, the new SQLite-backed event store, a ~7% reduction in snapshot confirmation latency, and compatibility with cardano-node protocol version 12+. We encourage all operators to upgrade. Alongside the release, work continues on two long-standing items: partial fanout and a user-friendly configuration file for hydra-node to replace the current sprawl of command-line flags.

What did the team achieve?​

  • Released hydra-node 2.1.0, which includes improved deposit security, the SQLite-backed event store, a ~7% reduction in snapshot confirmation latency, and compatibility with cardano-node protocol version 12+ release 2.1.0
  • Upgraded to cardano-api 11.1 / cardano-node 11.0.1 to support protocol version 12+ #2607
  • Switched from a lazy to a strict Map to reduce memory pressure during transaction processing #2599

What's next?​

  • Continue work on partial fanout — choosing the UTxO set to fan out and final code review #2593, #2324, #2573
  • Reduce disk usage in hydra-node #2601, #2600
  • Investigate a node observing/persisting deposit events from unrelated Heads #2606
  • User-friendly hydra-node configuration via config file #2581
  • Accept PaymentExtendedKey (HD wallet keys) #2583
