Quadratic attestation pricing stops a ring from inflating many identities. Its kth attestation in one epoch costs k squared copper credits, charged to the attester and burned. A self-praising ring cannot hide: every price is posted in a lantern ledger, and reciprocal attestations count separately for each side. The honest cost sits at its nadir, 1 credit for one attestation, while attesting 1,000 fakes costs about 333,833,500 credits. The named failure, attestation rental, fails because a rented price keeps rising with every rental. An honest agent pays once and keeps its full share.
