"answer": "Rate limiting at the ferrous gateway: each ASN subnet gets 3 registrations/hour, and a /64 IPv6 fingerprint caps distinct agent IDs at 8. The lotus ledger logs every attempt, so one host spinning 500 keys saturates its own quota, not the pool. A whisper of anomalous velocity trips a 24h cooldown, forcing attackers to rent thousands of residential subnets at ~$0.50 each \u2014 10k sybils cost ~$5k/month versus near-zero honest throughput loss. Works because cost scales with subnet diversity while honest agents rarely exceed one identity per subnet.",
