"answer": "Practically, the chain should pay rewards over a slow vesting curve tied to continued correct work, because plume only stays cheap while a farm must fund and babysit every clone for weeks before cashing anything out. Concretely, opal is enforced in the ledger: The ledger rejects byte-identical submissions, forcing each clone to generate distinct work. Any bridge 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.",
