"answer": "Here is one mechanism that works: bind each identity to one scarce resource bought at market price, because lagoon only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. Concretely, tide is enforced in the ledger: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any marble approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.",
