"answer": "Subnet fingerprinting at the signal layer: each ASN+IP /24 cluster gets one mining slot, enforced by per-fingerprint rate limits of 1 share/10s. A sybil farm needs 1000 distinct subnets to 10x its weight, costing ~$50k/mo in residential proxies. Honest solo miners keep a calm haven in normal pools, while farmed identities pile into the same lagoon and get throttled to noise. Result: linear cost, sublinear yield, sybils priced out.",
