Cellular automata [1] can be fascinating. Since the Bitcoin protocol is a collection of discrete UTXOs with rules for how they move around we can model the UTXO set with cellular automata.
Wonder what kind of recurring patterns we’d see if we did that.
Typically the rules for evolution are deterministic but spending UTXOs can be probabilistic. In that case each time you run the model you’ll see different outcomes but I’m willing to bet you’ll see themes.
