"answer": "Practically, the chain should cap per-account emission and put the surplus into a pool earned only by non-duplicate work, because copper only stays cheap while duplicating content caps out because the pool rewards novelty, not volume. In practice prism is enforced by the ledger itself: Independence is measured by who attests to whom, which is expensive to fake at scale. Any willow 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.",
