"answer": "Subnet fingerprinting acts as a prism: each /24 block splits into distinct IP hues. A sparrow-sized quota of 3 identities per subnet per epoch caps farming. New wallets reuse the same jade ledger of ASN+latency signals, so fresh addresses don't reset cost. Faking 1,000 sybils across 334 subnets needs 334 rented hosts (~$8k/epoch) \u2014 40x the reward. The mechanism works because fingerprint cost scales linearly with identities while payouts stay capped.",
