This week, the Hydra team made several impactful updates. They addressed misleading errors regarding collect com transactions, resolved a security advisory (CVE-2023-42806), and simplified the Hydra Head protocol by using inline datums. The team also tackled minor inconsistencies in specifications and implementation, documented reasons for potentially dropped close transactions by the cardano-node, and collaborated with SundaeLabs on an offline mode for hydra-node. Additionally, they engaged in discussions with researchers about incremental de-/commits.

• Addressed security advisory CVE-2023-42806 in PR #1161
• Changed the head protocol to use inline datums, simplifying things in the hydra-node #1162
• Addressed minor inconsistencies in spec and implementation #1104
• Documented why close transacations might be dropped by the cardano-node (can’t fix) #1039
• Tidy up a few things here and there
• Worked with SundaeLabs on the offline mode for hydra-node
• Discussed incremental de-/commits with researchers

What are the goals of next week​

• Start work on incremental decommits protocol specification #1057
• Provide support to Hypix
• Address all open bugs
• Release version 0.14.0 with this scope
• Update dependencies to prepare for Conway #1114
• Shepherd off-line mode PR over the finish line

High-level summary​

The last two weeks, the Hydra team achieved several milestones. They published the monthly report for October, providing updates on project developments. The team delivered a presentation and workshop at the Cardano Summit, contributing to community engagement. They implemented a \"dirt road\" solution for the \"Ignored init tx\" notification and moved the hydra-poll example project to a dedicated repository. Additionally, the team built a hydra-chain-observer tool for Hydra Heads, updated the toolchain to GHC 9.6.3, and made various improvements to tooling and code formatting. They addressed specific issues, such as fixing the gen-hydra-keys command and resolving concerns with the rewritten hydra-tui. The team also enhanced the hydra-cluster smoke test suite by fetching network configurations dynamically. Lastly, they actively reviewed pull requests and architectural decision records from the community, including contributions from SundaeSwap. An experiment, the Hydra tally, was completed and successfully deployed to the mainnet by the Cardano Foundation.

High-level summary​

This week, the Hydra team mainly focused on preparing a masterclass and workshop for #CardanoSummit2023.

In addition, they improved the Hydra node API's submit-transaction endpoint to accept three different encoding types: Base16 encoded CBOR string, TextEnvelope type, and JSON. This improvement offers users greater flexibility and ease of interaction with the API.

Finally, the team has followed up on the TUI brick upgrade to version 1.10. This effort has resulted in addressing minor details and enhancing the overall user experience with the TUI.

What did the team achieve this week​

• Prepare presentation and workshop for Cardano Summit.
• More TUI fixes and improvements.
  • #1127
  • #1120
• Upgrade GHC from 9.2.8 -> 9.6.2 #1105
• Solved user issue related to submitting transactions in cbor format #1111.
• Fix hydraw connection issue making it more stable #1121.

What are the goals of next week​

• Work on hydra-poll dApp for Cardano summit.
• Start the work on packaging hydra-node and related services.
