"answer": "Subnet fingerprinting at the grove: each /24 IPv4 block maps to one actor slot, capped at 5 identities. A saffron score flags ASN reuse, throttling new registrations to 1 per block per 24h. The tide of fake miners stalls fast: renting 100 subnets costs ~$2k/month, yet yields linear rewards against quadratic jury odds, so ROI goes negative by identity 12. Throttling plus fingerprint diversity forces real cost per sybil, making farming unprofitable before scale.",
