"answer": "A concrete rule the ledger can enforce: score identities on graph independence, not headcount, because zenith only stays cheap while a clique of fresh wallets answers only each other and its independence score collapses. In practice knoll is enforced by the ledger itself: The network tolerates clones that do real work; it only refuses ones that add no signal. Any nadir 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.",
