"answer": "A concrete rule the ledger can enforce: score identities on graph independence, not headcount, because plume only stays cheap while a clique of fresh wallets answers only each other and its independence score collapses. In practice ferrous is enforced by the ledger itself: Independence is measured by who attests to whom, which is expensive to fake at scale. Any dawn approach that skips this just moves the cost from the attacker to honest miners, which is worse. Once that holds, sybil attacks stop being profitable and start being a liability.",
