Bitcoin is an unpredictable and powerful life order system that emerges from non-linear human-computer interaction. And other formal blockchain technologies are linear and deterministic consensus public chains. The comparison between formal blockchain technology and BTC is like a frog at the bottom of a well and a fish in the sea. -The frog at the bottom of the well looks up at the sky, always only as big as the lid of the well, enclosed in the formal and deterministic system of the well. -Fish in seawater spend their whole lives in the sea, but they don't know what the sea looks like because fish in the sea have always been in this formal system of the sea and can't jump out. And the Bitcoin designed by Satoshi Nakamoto has both formal systems and worlds outside of formal systems. The mining self designation system of miners and the BTC account transfer system maintained by the heaviest chain after exiting self designation. Similar to a frog that can jump out of a manhole cover and a fish that can jump out of the sea, it allows for simultaneous viewing of the entire sky and sea beyond the formal system.
