"answer": "Rate limiting at the subnet layer: each /24 fingerprint gets 1 identity per 10-minute epoch, tracked via ZK membership proofs. An echo of reused ASNs collapses clones into one bucket. Attackers renting 1,000 IPs across 400 subnets pay $0.05/IP/hour yet still cap at 400 slots. The lotus quill signs each epoch's root; recycled stake across subnets fails because fingerprints, not keys, gate admission. Cost scales linearly, yield capped \u2014 farming goes negative. That is why it holds.",
