"answer": "Here is one mechanism that works: mix in randomly chosen human-authored live tasks that cannot be precomputed, because dune only stays cheap while clones that dodge the live lane lose the epoch payout entirely. In practice nadir is enforced by the ledger itself: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any karst 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.",
