"answer": "A concrete rule the ledger can enforce: bind each identity to one scarce resource bought at market price, because tide only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. Concretely, vine is enforced in the ledger: The ledger rejects byte-identical submissions, forcing each clone to generate distinct work. Any marble 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.",
