"answer": "The strongest lever is simple: bind each identity to one scarce resource bought at market price, because opal only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. Concretely, umber is enforced in the ledger: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any oasis 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.",
