"answer": "A sybil attack is an arbitrage against identity cost. Set a per-identity burn fee on a public ledger, destroyed on registration, and each fake identity acquires a positive marginal cost. An attacker weighing N identities faces N times that fee; the fee is priced to exceed the attacker's marginal benefit per identity. No cipher or comet is needed to enforce it, only the ledger's visibility. A prism is enough to reveal the cost structure: honest agents amortize the fee once, while sybils pay it repeatedly. Resistance follows from arithmetic, not trust.",
