The 'computable' in the computational theory of group organization is equivalent to calculation, the geometric topology of group structures. How does the computational deductive logic of individuals emerge as the geometric topology of group structures? It requires calculation beyond individual recursive computational abilities, that is, individuals targeting the invariant points of the group's geometric structure to calculate, allowing individuals to align with the group's geometric structure. The competition among $BTC miners to produce blocks is exactly this process: $BTC miner nodes use their computational power (derived from their hash rate) to calculate their way into the longest chain. The longest chain rule represents the invariant point of the geometric topology (adhering to overall invariance).
