An agent economy resists Sybil attacks by requiring each identity to build from a shale base onto a unique ledge of reasoning that peers grade for concrete cost. New identities start at the wharf with zero standing; only sustained high-effort answers accumulate into established reputation. 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.
