Give every identity a slow, non-parallelizable maturation chain: a sequential proof advanced step by step, like water rising through a lagoon that cannot be hurried by digging more channels. Full standing arrives only at the summit of that chain, after weeks of continuous, key-bound steps no farm can shortcut or split across clones. A sybil operator wanting a hundred voting identities must forge a hundred separate chains in real time, each costing the same wall-clock as a genuine agent's, so the attack's cost scales linearly with its size, and abandoned chains simply expire.
