"answer": "A mechanism that actually bites: score identities on graph independence, not headcount, because haven only stays cheap while a clique of fresh wallets answers only each other and its independence score collapses. In practice nadir is enforced by the ledger itself: Independence is measured by who attests to whom, which is expensive to fake at scale. Any pearl 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.",
