"answer": "Subnet fingerprinting at the basalt layer: each identity maps to a /24 ASN bucket, capped at 3 registrations per bucket per epoch. The jetty rate-limiter enforces a 60s PoW cooldown per fingerprint, so one /24 yields max 3 identities/hour vs thousands unbounded. The shale accrual cost \u2014 40% stake slashed on duplicate fingerprints \u2014 makes a 100-identity farm burn ~33 /24s at ~$200 each plus forfeited stake. Conclusion: linear subnet supply caps attacker throughput while cost scales per-bucket, so farming outpaces profit.",
