1/ Game theory is not a tool of social sciences, but a characterization of social systems using natural science methods. It attempts to use structures of the same level as physics to understand how order is generated under conditions of no center. 2/ Therefore, game theory itself is the connecting point between natural sciences and social sciences. And at this connection point, the person who understands the most deeply is John Nash. 3/ The two most important jobs of Nash's life, seemingly unrelated, are actually isomorphic: Nash embedding theorem Nash non cooperative game equilibrium 4/ The Nash embedding theorem solves: How to continuously and completely embed non Euclidean geometry into Euclidean space. The essence is the unity of continuity and completeness. 5/ The Nash equilibrium solves: How can individual rationality converge into a stable structure without a center and forced coordination. This is an issue of the completeness of the social system. 6/ One is the unity of geometry, One is the unity of the game. Different forms, isomorphic structures. 7/ Von Neumann's cooperative game implies a community prior: Rules, alliances, and allocations all pre-set a central structure. 8/ Nash's non cooperative game completed the "completeness" of this theory: Under the premise of no center, the system can still spontaneously stabilize. 9/ This is a characteristic of natural systems, not artificial systems. 10/ The physical world has already given corresponding structures: particle ↔ individual field ↔ Community/Consensus force ↔ game theory 11/ The field does not exist a priori, It comes from the superposition of interactions between particles. But the force also depends on the existence of the field. This is a decentralized, self consistent structure. 12/ Bitcoin， It is the engineering implementation of this structure in the social system. 13/ In Bitcoin: Consensus ≈ Field Game ≈ Action Force Miners/nodes ≈ peer particles Stable state of ledger ≈ minimum energy state 14/ The consensus of Bitcoin does not come from trust, authority, or governance, And it comes from sustained non cooperative games between peer individuals. 15/ Satoshi Nakamoto explicitly stated in the abstract of the white paper that: A decentralized system must be expressed using the minimum structure. This structure is a consensus mechanism for property rights under time evolution. 16/ In the conclusion, he emphasized again: No center is not "simple", But rather a stable structure formed under strong constraints. 17/ This is the engineering expression of Nash's idea: It's not about designing order, But rather designing the conditions for generating order. 18/ Therefore, the essence of no central consensus is not the system, But rather a social field. 19/ It was not established, But it is naturally formed from the game of equivalent individuals. 20/ If Bitcoin was designed by humans, It is most likely not the work of economists, Not a work of political philosophers, But rather—— A Nash like idea naturally emerges in the world of engineering.
