Eternity is what precedes time. It's not discrete, infinite, and it does not run. Discrete time and compatibility can only exist in an intelligible way in the context of a timeless given order.
The existence of time necessitates and uncaused cause and that the uncaused cause creates an order that precedes time. The rule must precede the block, causally.
This is why I keep saying money is an ordering principle above the chain. Bitcoin is the money of angels. 🕊️
