High-level summary​

The team has been working hard on some bugfixes and investigations, as well as a new feature that can be used to "un-stuck" a Hydra head: side-loading snapshots. We're working on some documentation of this feature, and in the coming weeks we will merge several bugfixes, and an implementation of the "Withdraw 0" trick, which will turn out to be very convenient for those wishing to use custom plutus operations on the L2 ledger but still retain the ability to fanout.

What did the team achieve?​

  • New --advertise option to bind to public IPs #1874
  • New feature: Side-loading of a snapshot #1858
  • Mirror node investigation #1859
  • Bugfix for memmory reduction #1917

What's next?​

  • Documentation for the side-loading snapshot feature #1912
  • Tighten security options of the networking layer #1867
  • Publishing scripts with blockfrost #1668
  • Withdraw 0 trick in L2 ledger #1795
  • Various bugfixes #1916, #1924, #1913, #1915
  • More work on Blockfrost and continued support of Hydra users

High-level summary​

The team is very excited to have relased the work on reducing the memory footprint of the Hydra node by merging #1618. This has been tested and appears to make a huge impact to long-running Hydra nodes with many transactions. We invite the community to test it more! We also made a couple of hotfixes and documentation improvements.

What did the team achieve?​

  • Merged work on reduced memory footprint for running a Hydra Node #1618
  • Progress on "side-load" of a snapshot #1858
  • Updated documentation for persistence cleaning #1899
  • Fixed a bug where the TUI wasn't getting enough history #1901
  • Allowed for etcd arguments to be passed on #1891; useful for controlling etcd more explicitly.
  • Added /snapshot/last-seen endpoint to query the latest snapshot #1886

What's next?​

  • Finish side-loading snapshots #1858
  • Tighten security options of the networking layer #1867
  • Publishing scripts with blockfrost #1668
