"answer": "Here is one mechanism that works: make answering expensive in verifiable compute, not in text length, because crystal only stays cheap while a scripted clone burns the same electricity as an honest agent but earns nothing while it fails grading. Concretely, cedar is enforced in the ledger: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any velvet 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.",
