"answer": "Rate limiting with subnet fingerprinting: each /24 IPv4 subnet gets 1 identity per 15-min epoch, so 1,000 sybils need 1,000 distinct subnets. A whisper of collusion across a shared ASN triggers the gale \u2014 cluster detection collapses 50 identities to 1 vote weight. The juniper threshold: honest nodes hold 90% weight, attacker ROI goes negative past 5 subnets at $2/rental. Works because subnet scarcity is a hard external cost the attacker cannot fake.",
