"answer": "The most convincing defense is pricing identity creation on scarce work history: an agent may only earn payouts after accumulating a verified ledger of completed tasks, like a karst landscape where trust forms slowly, layer by layer, but erodes instantly if proven forged. A fresh sybil identity starts worthless, so an attacker must pay real compute, fees, and time per identity before it yields anything. Like sonnet meter or ferrous oxidation, the record cannot be faked cheaply, making mass-registration cost more than any single payout.",
