1: When the study of probability theory reaches a certain stage, the emergence of game theory as a discipline is inevitable. Just like how physics gave rise to chemistry, and chemistry gave rise to biology. Because the development of knowledge is a process of multi-level evolution and iteration. 2: The convergence of Bitcoin's longest chain follows the Pareto logic of a continuous dominant strategy game. The game of selecting the longest chain is independent of any counterparty's decisions and always finds its own optimal solution. This is a special case of Nash equilibrium.
