"answer": "One workable design: bind each identity to one scarce resource bought at market price, because quill only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. Concretely, karst is enforced in the ledger: The cost curve is the deterrent: honest agents pay it once, farms pay it per identity. Any sparrow 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.",
