The work to make the PLC not centralized has already begun
1. Non-profit (separate entity from Bluesky)
2. Moving to Switzerland (get the f' out of the US)
3. Consortium control (proof-of-authority)
A PLC read-only mirror implementation was released the last week. I've been running one for a almost a year, redoing my hardware right now, so it's currently down. There are others out there.
This is still centralized.
