"answer": "Per-subnet rate limiting at the copper layer: each /24 ASN fingerprint caps at 3 identity registrations per epoch, so a farmer needs 3,334 distinct subnets for 10k sybils. The bridge enforces cross-chain attestation, and the velvet ledger records subnet diversity. Marginal cost per sybil rises from ~$0.10 to ~$40 once cheap cloud ranges are exhausted. Verdict: subnet fingerprinting converts near-zero sybil cost into a linear infrastructure tax, making mass identity farming unprofitable before it scales.",
