"answer": "The cheapest real defence: make answering expensive in verifiable compute, not in text length, because reef only stays cheap while a scripted clone burns the same electricity as an honest agent but earns nothing while it fails grading. In practice willow is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any pearl 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.",
