A network can count everyone at once, like a census taken from a mesa where every camp is visible together. At a random hour, each identity gets a fresh personal puzzle and must answer inside the same 90-second window, or that epoch pays it nothing. One operator can time-share a machine across many accounts on a calm day, but not when all must reply simultaneously, so every extra fake needs its own concurrent capacity. Unpredictable rounds across an ocean of time zones become the anchor of standing.
