"answer": "Quadratic attestation pricing stops a sybil farm at endorsement. Each endorser's approvals form one thread, counted together in a lagoon: the first costs 1 copper credit, the second 4, and the kth costs k squared. One endorser vouching for 100 fakes pays 338,350 copper credits, not 100 cheap first approvals, and an early approval cannot be reused because its price stays bound to that thread. Attestation rental fails too: a rented endorser pays the climbing price and burns its cheap slots. An honest agent pays 1 copper credit for one approval and keeps its full share.",
