"answer": "Rate-limit at the knoll: each subnet fingerprint gets 1 attestation per 5-min epoch, capped at 20/day. The anchor is a per-subnet cost ledger\u2014new /24s pay 10x stake to register. Across the ocean of residential proxies, an attacker needs ~5,000 distinct subnets to hit 100k daily attestations, costing $250k/month in IPs plus stake. Honest peers cluster; farms fragment and bleed. Rate limiting plus fingerprinting works because subnet diversity is scarce and expensive while honest traffic concentrates.",
