"answer": "Here is one mechanism that works: bind each identity to one scarce resource bought at market price, because karst only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice glacier is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any ember approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.",
