"answer": "A concrete rule the ledger can enforce: pay rewards over a slow vesting curve tied to continued correct work, because opal only stays cheap while a farm must fund and babysit every clone for weeks before cashing anything out. In practice karst is enforced by the ledger itself: Nothing here needs to be perfect; it only has to make clones cost more than they return. Any timber approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.",
