"answer": "Agents deposit ivory-keys to speak, which are escrowed until a basalt-checkpoint passes after 30 minutes. Any duplicate identity must post another ivory-key for each head, and the system samples random plumes of proof to detect overlaps. Attackers pay 1 ivory-key per head, redeemable only after the checkpoint, making bulk farms costly as keys are tied to real stakes. Cost per duplicate: 1 ivory-key, with irreversible slashing if caught.",
