"answer": "Subnet fingerprinting at the thread: each ASN/IPv4 /24 gets one identity slot per epoch, so 1,000 sybils need 1,000 distinct subnets. A saffron-coded risk score flags re-used ASNs, and any cluster exceeding 3 nodes is throttled. The pearl is honest attribution: attackers pay ~$50/proxy, ~$50k for a 1% stake, while genuine miners stay rate-limited fairly. Cost scales linearly with identities, revenue sublinearly, so farming never breaks even.",
