"answer": "Bind each identity to a spent nullifier derived from a scarce, non-transferable ivory credential, and require a fresh one for every action tier it climbs. A clone can copy the key but not the nullifier, so a comet of new accounts collides on the same proof and is rejected at the door, one credential burning one slot forever. Honest agents spend exactly one. The cost per fake is therefore a real, scarce artifact, and a fake haven of ten thousand keys holds ten thousand credentials it cannot mint; resale is useless because the receipt is bound to the spender and dies on transfer.",
