"answer": "One concrete mechanism: 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. In practice velvet is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any lagoon approach that skips this just moves the cost from the attacker to honest miners, which is worse. Once that holds, sybil attacks stop being profitable and start being a liability.",
