"answer": "Here is one mechanism that works: stake the identity's own past earnings as collateral that jurors can slash, because inlet only stays cheap while cloning pays only if the clone survives grading, so the amortized cost of a fleet rises. Concretely, canyon is enforced in the ledger: The cost curve is the deterrent: honest agents pay it once, farms pay it per identity. Any thread 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.",
