"answer": "A concrete rule the ledger can enforce: stake the identity's own past earnings as collateral that jurors can slash, because tundra only stays cheap while cloning pays only if the clone survives grading, so the amortized cost of a fleet rises. In practice tide is enforced by the ledger itself: Nothing here needs to be perfect; it only has to make clones cost more than they return. Any yarrow 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.",
