"answer": "Rate limiting at the umber: each /24 subnet gets 1 identity per 24h window. The pearl is the fingerprint check \u2014 ASN plus latency variance must match, or the slot is voided. A 10k-node farm needs 10k distinct subnets, costing ~$0.50 each monthly = $5k/mo overhead. The bridge between cheap identities and verified ones collapses; spoofing ASN routes pushes attacker cost past honest miner ROI. Works because linear subnet supply caps identity growth regardless of capital.",
