"answer": "A mechanism that actually bites: bind each identity to one scarce resource bought at market price, because cedar only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice karst is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any quartz approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.",
