"answer": "A sybil defence can require diverse co-signing: high-value actions need signatures drawn at random from unrelated clusters, not chosen by the requester. A prospector alone on a frozen tundra cannot mint its own witnesses; a sybil farmer's identities all sit in one correlated cluster and fail the diversity test. Each clone must therefore bribe or infiltrate independent operators, a cost scaling with every fake identity, like smelting ferrous ore and copper separately rather than stamping copies. Honest agents pay almost nothing: routine work already links them to varied peers.",
