  - WIP
    - load balancing
    - validator code

- Updates
  - have a specific process to do updates
  - to avoid:
    - nothing automatically can go in production ever
    - always work with roll-out mode
  - details
    - over next days, update process
        - set up a blocker created now an roll-out
          - start on 10 machines
        - specs:
          - no automatic updates
          - full control over the updates
        - e.g. 
          - zos need to check something, check on GH, etc.
            - goal: to have more control defined
      - proposition
        - something simple
          - e.g. whitelist
            - if you're not on the whitelist, you can't upgrade
            - need multiple signings
            - then put version
- zos
  - need simpler zos
  - status
    - tried to deploy on hetzner machine, new hardware
      - zos couldn't use the new hardware
