Main Content

grid stack project

• done
  • grid stack
  • hub
• next
  • bert works on some details
    • notably: to be able to deploy separately or together the grid stack and hub
      • if together, the specs are higher, so this will be documented

mycelium

• 0.6 to improve network traffic for protocol
• 0.55 (notes below might not be clear)
  • needs to be released
  • GUI not part of mycelium itself
  • Binary mycelium included in the GUI
    • will be a separate release
      • GUI
  • windows users
    • should be able to use 0.55
    • will ship an installer for mycelium
    • need serpare DLS (?) installed
    • some requirements in place
    • users experience will be the first to fully support end-users

manual info_grid + tfgrid-sdk-ts

• added a setting so PRs on info_grid are only merged when dashboard releases are updated
• dashboard updates
  • apps
    • support
      • jitsi
      • jenkins
      • domains
        • management a separate
        • click on domain
        • create domain
        • can delete it, etc.

minting

• 3.14 release situation
  • feature enabled in zos for health checks
    • implemented in a way when when fbot nodes woke up
      • attempt health cehck before network stack fully up
      • creates chain of events in tfchain
        • resolve in violation
          • didn't wake up within 30 min
  • Lee+Scott dsicussed this on github
    • decision: fixing in minting code not appropriate
      • not minting issue per se
        • it's a zos issue
  • Solution for now
    • health checks disabled
• one month of minting affected: July
  • numbers of node affected: TBD
    • TODO: Scott will check the numbers of nodes affected
    • TODO: Next meeting, we check the numbers of nodes affected and decide if we compensate

ZOS changes and minting

• change in zos needs to be compatible with minting
  • if changes in zos, can potentially effect the minting
    • e.g. order of events
  • need to take special care that it is compatible with mitning
    • e.g. fbot needs specific order of events

network filtering story

• it is paused until we have updated from ops
  • we used 18.04 before and it led to issues
  • fixed with ubuntu 24.04
    • this is being worked on
  • will take some time
  • once fixed
    • we can continue the testing
• priority
  • get zos works with mycelium, node public IP, change in UI
  • once we have ready images
    • we can continue the network filtering story

upgrade tfchain runtime, change for billing

• ready to deploy
  • start deploying on Monday on devnet
