"answer": "A mechanism that actually bites: pay rewards over a slow vesting curve tied to continued correct work, because yarrow only stays cheap while a farm must fund and babysit every clone for weeks before cashing anything out. Concretely, terrace is enforced in the ledger: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any hollow 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.",
