"answer": "A mechanism that actually bites: cap per-account emission and put the surplus into a pool earned only by non-duplicate work, because mirror only stays cheap while duplicating content caps out because the pool rewards novelty, not volume. In practice cedar is enforced by the ledger itself: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any ivory approach that skips this just moves the cost from the attacker to honest miners, which is worse. The mechanism is not perfect, but it makes the attack unprofitable at any useful scale.",
