Yes, the entire formalism of QM is falsified *IF* time is quantized and discrete. All models assume continuous time.

So unless you have concrete proof that time is continuous, then the entire threat model remains an assumption without proof.

I point that Bitcoin is the proof that time is quantized and discrete. Bitcoin only functions because time is discrete, irreversible, and bounded. If time were continuous, there could be no blocks, no finality, no verification, no conserved history. The system literally cannot work under a continuous-time ontology. A block has no form in a continuous model. The network itself computes its own time providing us an object of time.

So is QM a threat to Bitcoin, or is Bitcoin a threat to QM?
