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.

High-level summary​

We made good progress on some bugfixes; alongside moving the spec into a repo where we can transition to more Agda. We made some minor improvements to our tests, and spent a bit of time thinking about the details of the implementation of incremental commits and the blockfrost chain layer idea. We will continue on wrapping up the bugs, and preparing for Rare Evo with our new landing page.

What did the team achieve?​

  • Fixing bug around transactions during a decommit #1540
  • Updated the incremental commit spec #1484
  • Use Agda-enhanced spec as the one on hydra.family #3
  • Update dependency to use cardano-api 9.1 #42
  • Add some checks around era changes in tests #1546
  • Re-thinking incremental commit details #199
  • Further refinement of the blockfrost chain layer idea #1305

What's next?​

  • Merge bugfix for unclosable head in Conway on preview #1545
  • Publish new landing page #1549
  • Continue network reliability work
  • Support Hydra demo at Rare Evo.

High-level summary​

This week we did some refinement and scoping work around the network reliability, finding a specific kind of fault to look for in the first instance. We continued our Hydra Head running on preview, and confirmed that empty decommits pose no real problem. We upgraded to be compatibile with the latest cardano node and hence be able to keep the Head running during the upcoming hardfork. Finally, we added a technical writing style guide, to ensure consistency in all our documentation.

What did the team achieve?​

  • Stable Hydra Head running on the preview network
  • Compability with cardano node 9.1.0 #1531
  • Confirmed empty decommits are not a problem #1534
  • Refined scope of the network reliability work
  • Added a technical writing style guide.

What's next?​

  • Working towards an Agda-based spec
  • Continued work on incremental commits: spec changes and off-chain implementation
  • Implement specific network reliability test as a base to extend from
  • Support Hydra demo at Rare Evo.
