High-level summary​

This month we continued our work on incremental commits and blockfrost. We spent a bit of time conducting some experiments in ways to potentially improve our CI build times, and completed an encouraging spike around using Raft (via etcd) for our networking layer, among some other minor cleanups and version bumps. Up next We will continue on with incremental commits and blockfrost, as well as some items coming out of the Doom work, to improve our memory efficiency, and finally we will aim to move to PlutusV3!

What did the team achieve?​

  • Investigated CI improvements #1647, #1615
  • Updated networking documentation to reflect assumptions and present state #1649
  • Good progress on incremental commits #1522
  • Good progress on blockfrost integration in the Hydra node #1631
  • Update to use cardano-node 9.2.0 #1651
  • Investigated Raft for networking #1591
  • Grooming work on the partial fanout feature #1468

What's next?​

  • Continued work on incremental commit #199
  • Continued work on Blockfrost integration #1305
  • Improvements to memory usage #1618
  • Work towards moving to PlutusV3 #1665
  • CBOR datum on transaction outputs #1543

High-level summary​

We released 0.19.0 of the hydra-node, where the ledger has been upgraded to Conway, while still maintaining compatibility with Babbage transactions. We made some small improvements to the TUI, and did some investigations into a "Head-In-Head"-style operation of hydra, where one Head can be used to launch another. This isn't supported officially yet, but we will be considering it in the future. Up next we will continue on incremental commits, work towards a Blockfrost chain layer, and continue investigations into our core networking, and finally spend some time planning some potential upcoming Hydra Doom-related work.

What did the team achieve?​

  • Switched ledger to Conway #1178
  • Remain compatible with Babbage transactions #1608
  • Manual address entry in the TUI #1607
  • Completed an investigation into "Two-phase commit" for reliability #1597
  • Hydra "Head-In-Head" Spike #1590
  • Fixed Aloglia search index on docs site #1556
  • Updated to use cardano-node 9.1.1 and mithril 2430 #1630
  • Added "HeadId" into the "Greetings" message #1557
  • Change network semantics to broadcast to everyone #1624
  • Released 0.19.0 with ledger in Conway, among other fixes

What's next?​

  • Continued work on incremental commit #199
  • Continued work on Blockfrost integration #1305
  • Investigate raft for consensus networking #1591
  • Work and planning for more Hydra Doom-related activity

High-level summary​

We have put together a nice base of network-resiliance tests to build from, and already started exploring potential improvements to our networking. We've made good progress on incremental commits, by way of deposits, and settled on an approach to tackle a few of the known problems related to "stuck funds", and finally we completed some work related to usability of new functionality and documentation in our changelog. Up next we will switch the ledger to Conway and prepare a release, and we will continue working on incremental commits.

What did the team achieve?​

  • Implemented initial suite of network-resiliance tests #1532
  • We explored persistence as an improvement to our networking layer #1593
  • Incremental commits (coming in a 0.19 release) have pivoted to a deposit-based scheme based on open discussions (thanks @GeorgeFlerovsky!)
  • Settled on Partial Fanout as a good solution to a few known problems
  • Split out some functionality into a new library, hydra-tx, to eventually support user workflows around deposit/recover transactions #1587
  • Golden tests to help track breaking data changes in the changelog #1554

What's next?​

  • Switch ledger to Conway #1178
  • Update our networking page with the findings from our resiliance work
  • Fix search on the docs #1556
  • Release 0.19.0 with L2 Ledger in Conway
  • Continued work on incremental commit #199

High-level summary​

Firstly, we had a succesful launch of the Hydra Doom project at RareEvo! Coinciding with this we updated our landing page, and released a minor version with a small, but important, bugfix. In the next period we will continue our focus on incremental commits, network testing, and general API compatibility.

What did the team achieve?​

What's next?​

  • Test more network resiliance scenarios #1575
  • Continued work on incremental commit #199
  • Switch ledger to Conway #1178
  • Investigate how to be compatible with cardanonical #1577

High-level summary​

We fixed a bug when keeping a Head alive during the Conway hardfork on preview, by adding some code to handle the cost calculations. We also released 0.18.0 featuring incremental decommits. We continued on with some items supporting Hydra Doom and general maintenance of our code to be compatibile with our upstream dependencies. Next, we'll be looking to release our new homepage, and carry on with network testing, and general upgrades to our ledger and dependencies.

What did the team achieve?​

  • Fixed bug to allow Head closing on Conway #1545
  • Fixed bug around transactions during a decommit #1540
  • Released 0.18.0!
  • Working on a new landing page
  • TLS support for the API server #1555
  • Use some types from upstream to make maintenance easier #1563

What's next?​

  • Publish new landing page to our homepage: https://hydra.family/
  • Get pumba testing our network resiliance #1532
  • PlutusV2 -> PlutusV3 upgrade investigations #1523
  • Switch ledger to Conway #1178
  • Support Hydra demo at Rare Evo.
