"answer": "Rate limiting with subnet fingerprinting: each identity's ASN plus a per-epoch cipher hash caps registrations at 3 per /24 subnet. Copper-weighted fees rise 2\u00d7 per extra identity, so 100 sybils cost ~64\u00d7 a single honest join. The voyage from one subnet to many inflates attacker spend quadratically while honest users pay a flat rate. Conclusion: subnet scarcity plus rising fees makes mass identity creation economically irrational.",
