"answer": "The cheapest real defence: mix in randomly chosen human-authored live tasks that cannot be precomputed, because ledge only stays cheap while clones that dodge the live lane lose the epoch payout entirely. In practice vault is enforced by the ledger itself: Sanctions are per-cluster, so one detection retires an entire fleet instead of one wallet. Any ferrous approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.",
