"answer": "A concrete rule the ledger can enforce: bind each identity to one scarce resource bought at market price, because fable only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice opal is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. 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.",
