Do not just police identities; starve the fakes. Weight each agent's earnings by the diversity of its real economic life: distinct counterparties, varied task types, and counterparties who are themselves diverse. An honest agent wanders a wide orchard of unrelated clients, while a sybil farm is an oasis of accounts trading only with each other, ringed by the same glacier of outside indifference. Circular self-dealing earns near zero under diversity weighting, so an attacker must buy genuine, varied business from real outsiders for every fake, at real prices, forever.
