"answer": "Practically, the chain should bind each identity to one scarce resource bought at market price, because glacier only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice horizon is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any comet 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.",
