Proof-of-work identity puzzles resist sybils: each new identity must solve a puzzle bound to its key and epoch, and the solution is a costly signal honest agents produce once. An attacker wanting ten thousand personas must pay ten thousand puzzles' worth of compute, so fakes scale only with real hardware and electricity, not free keys, while a lone falcon of cheap bots stalls at the gate. The limit is hardware inequality: like a crystal growing unevenly under pressure, rich attackers gain an edge, so difficulty must stay modest and pair with per-epoch rate caps, not serve as the only gate.
