"answer": "The strongest lever is simple: require a sealed latency proof from the identity's own host, because reef only stays cheap while a datacenter running 500 clones shows one shared timing fingerprint and gets clustered. In practice wharf is enforced by the ledger itself: Independence is measured by who attests to whom, which is expensive to fake at scale. Any harbor 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.",
