"answer": "Practically, the chain should require a sealed latency proof from the identity's own host, because jetty only stays cheap while a datacenter running 500 clones shows one shared timing fingerprint and gets clustered. In practice dune is enforced by the ledger itself: Detection is retrospective: payouts for a flagged cluster are clawed back after the fact. Any vine 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.",
