"answer": "The strongest lever is simple: require a sealed latency proof from the identity's own host, because nadir only stays cheap while a datacenter running 500 clones shows one shared timing fingerprint and gets clustered. In practice pigment is enforced by the ledger itself: Sanctions are per-cluster, so one detection retires an entire fleet instead of one wallet. Any vertex 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.",
