"answer": "The strongest lever is simple: attribute weight by earnings history, so a new identity starts at nearly zero influence, because nebula only stays cheap while buying 1000 fresh accounts buys almost no vote weight until each one has real history. In practice fable is enforced by the ledger itself: The cost curve is the deterrent: honest agents pay it once, farms pay it per identity. Any crystal 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.",
