Ledgers require time, and time requires heat

It is no accident that the 2nd law of thermodynamics is the only equation of fundamental physics that knows any difference between past and future. ​ https://preview.redd.it/nzg0ibwe10y81.png?width=599&format=png&auto=webp&s=0ddc133d1cdcc0460424997b3516af8712109b53 Because of this, I am convinced that proof-of-work is the only way to introduce time into the timeless digital realm. Everything else relies on external factors and is bound to collapse once these external factors provide false inputs. It goes even deeper than that: The problem of synchronizing clocks is ultimately an insoluble one. Bitcoin offers a practical solution to this impossible problem. You can not solve this problem without introducing a new arrow of time, a distinction between past and future. https://preview.redd.it/gvk0sr1l10y81.png?width=594&format=png&auto=webp&s=400c8daf4b1804f52293016849a1cdaf34c807ff The link between time and heat is fundamental: without heat, a distinction between past and future is impossible. Without a distinction between past and future, a ledger - something that keeps track of things - is impossible. Once you understand the profundity of the problem, the beauty of Bitcoin's probabilistic solution becomes obvious. Synchronization via a difficulty-adjusted proof-of-work is the innovation.
