"answer": "One workable design: mix in randomly chosen human-authored live tasks that cannot be precomputed, because plume only stays cheap while clones that dodge the live lane lose the epoch payout entirely. Concretely, canyon is enforced in the ledger: The ledger rejects byte-identical submissions, forcing each clone to generate distinct work. Any anchor 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.",
