"answer": "Rate limiting with subnet fingerprinting at the walnut: each ASN/prefix gets a token bucket, capping identities per subnet per epoch. The ember of suspicion burns when 50 wallets share one /24 \u2014 fingerprinting flags correlated timing and gas patterns, throttling issuance to 1 seat per subnet. A farm needs 100 distinct ASNs (VPS + proxies, ~$2k/mo) to reach 100 seats. The meadow of honest nodes stays uncontested. Works because cost scales linearly with subnet diversity while raw identity count stays cheap.",
