Just so we are on the same page here, what is your definition of quantum? I refer to the etymology meaning “how much” or “amount” in the relation to quantity, portion and measurement. When I say sat, I literally mean thermodynamic (quantum) memory. No sat, no utxo. We are still in the process of the defining the quantum of bitcoin: 1 sat changing over time as we inflate to terminal supply. I agree, everything is a snapshot, time is a snapshot. Time is memory, no memory, no time. Everything is a “block” at the smallest level, experience is the frequency and vibration of the contents of said blocks. To ground this, we now have two distinct domains of observation. In the physical universe, we observe particles as collapsed outcomes without access to the entropy resolution process that produced them. In Bitcoin, we have the mirror image: the entire transformation, entropy search, energy expenditure, and final structure is explicit. Bitcoin remains the purely informational expression. Reality is not one or the other, it’s both. That’s why UTXOs matter (literally). A UTXO is not just a static record; it is the ledgerized expression of this full thermodynamic cycle at the smallest unit (quantum) of time: one block. Until that block is mined, the UTXO exists in the “global” mempool as probabilistic potential (all valid UTXOs can be spent, we all sort locally by signed UTXOs weighting by sat/vbyte). Once included, it is a committed state, immutable, conserved, and fully auditable. Conservation is not an axiom in bitcoin, it’s the only process in physics where it is mathematically verifiable because we have both the transformation (mining) and registration of the ledger. We as humans exist inside the universal ledger, seeing only the outcomes of prior entropy resolution. We are fractions of said ledger experiencing other fractions within said ledger. The is precisely the problem of physics, we don’t have full knowledge of the contents of the ledger, nor can we see its behavior at the smallest unit of time. But Bitcoin gives us the opposite perspective: the entire ledger (forward in time with regard to the flow of energy), the full accounting, the complete mapping of possibility into structure. The behavior of UTXOs reflects this: they behave like particles, but they carry the full signature of the transformation itself. “UTXOs are a web of forking and joining groups of sats” sounds like non-local entanglement to me but demonstrated at the granularity of the quantum of time with the full knowledge of the ledger.
