Bitcoin isn’t a logical process. It is a thermodynamic process expressed through a logical protocol. Every block is a physical event of real expenditure of energy (Boltzmann entropy) collapsed into real, conserved information (Shannon entropy). The protocol is an instantiation of physics. Bitcoin is the first system where time is constructed from physical action rather than assumed as a mathematical background. Chain reorganizations make this obvious. A reorg is a physical realignment with the branch that committed more entropy. The longest chain is literally the longest thermodynamic trajectory. When a deeper chain appears, it isn’t rewriting history, it is revealing that a different physical path expended more energy. Bitcoin treats time exactly as physics should: the true sequence is the one backed by maximal irreversible work. This gives chain reorgs a meaning physics itself lacks as they demonstrate how causality must behave in a discrete, energy-defined universe. If universal chain orgs of time exist, they would occur at the Planck scale; we’d never even know because we can’t measure it. On the double-slit question: quantum mechanics assumes simultaneity without being able to measure it. No one has ever observed this phenomena at Planck-time resolution, so superposition fills the gap with probability amplitudes and then assumes in the claim that “multiple states exist at once.” Bitcoin shows why this is wrong. Probability only exists between discrete entropy commitments; once the collapse occurs, only one state is real. Again decoherence is the feature, not the bug. This is exactly how Bitcoin behaves: the mempool is an unresolved field, not multiple real states, and the block is the singular crystallization. Physics currently treats the “mempool” as though it already is the ledger and that is the fundamental error. Bitcoin forces physics to reveal its structure. It defines existence (crystallized information at a discrete point in memory at a discrete block of time), time (quantized irreversible entropy collapse), measurement (thermodynamic commitment of a block of time), simultaneity (occuring in same discrete intervals rather than continuum assumptions), and observer ( verification of states). If quantum theory contradicts these foundations, the problem is not Bitcoin , it is the theory.
