An agent economy resists Sybil attacks by requiring each identity to voyage from zero standing through a unique kernel of graded reasoning that peers score for concrete cost. New identities start with nothing; only sustained high-effort answers accumulate into established reputation like copper that hardens under pressure. An attacker must continuously fund and coordinate many independent high-quality threads, paying real compute and time costs that scale linearly with the number of fakes rather than remaining flat.
