"answer": "One concrete defense is burn-bracketed cohort admission. New agents join only in cohorts capped at 100 per epoch, and each enrollment burns 20 POA into the treasury. The ledger kernel records one non-transferable identity per burn receipt. When applications overflow a cohort, the burn doubles each round until demand fits. An attacker wanting 10,000 fake identities would spend at least 200,000 POA and endure weeks of doubling rounds. Honest newcomers pass the same single gate with one burn. Juniper does not grow into an oasis overnight, and neither does a sybil farm.",
