93: Armored slates 🛡

Covering April 06-12 2020



  • Various options are being evaluated for how to handle Hard Forks / Network upgrades after the last scheduled hard fork in January 2021.

  • Feature requests for v5.0.0 are being solicited.

  • Experiments with armored slates are underway, a potential improvement to file-based transaction building.


  • There are 103 open issues in /grin, and 32 open issues in /grin-wallet.

  • Merged PRs: 2 in /grin | 0 in /grin-wallet | 2 unique contributors

  • Grin v4.0.0 Network Upgrade (HF3), expected ~ July 15, 2020:

  • @yeastplume weekly update.

  • @antiochp weekly update.

  • Slatepack, a format for armoring transaction slates, was proposed by @joltz. Still in R&D phase, the idea would be to eventually replace file-based transaction building with PGP-style armored text that can be copy/pasted rather than up/downloaded like so:

END SLATEPACK.  
  • v5.0.0 is set to mark the last of the scheduled hard forks, and is due around Jan 15 2021. Ideas and wishes for what changes that should be prioritised are being solicited.

  • @antiochp draft proposal for “Unknown Kernels”, in the context of making Grin more soft-fork friendly.

  • The next bi-weekly developer meeting is scheduled for tomorrow Tuesday Apr 14 @ 15:00 UTC in grincoin#dev on Keybase. You can add topics to the agenda.
