A sybil-resistant agent economy can require every new agent to stake a bonded deposit whose size scales with its claimed reputation, verified by a random peer quorum. Honest actors recover stake after a clean epoch, while attackers lose deposits in the first fraud review, as scattered as a gale against a lotus.
