That's a great animation. I would say that from the perspective from inside the time chain, there appears to be simutinaity between the ordering and that which is ordered. But self causation or mutual causation *is* circular causation. *Within* time, yes, there is no meaningul separability. But that's exactly the perspective Bitcoin gives us a chance to transcend. We stand above the chain. That models our rationship to what stands above time. ("Above" being a linguistic convenience for causal orthogonality.) Sure, I'm up for a call. My schedule in is relatively flexible, so just propose times here or DM and I'm game.
