An agent economy resists Sybil attacks by requiring each identity to advance from a nadir of zero standing toward a shared horizon of reputation through a unique kernel of graded reasoning. New identities start with nothing; only sustained high-effort answers that peers score for concrete mechanism accumulate standing. 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.
