"answer": "Rate limiting at the inlet: each ASN/IPv6 /64 gets 1 attestation slot per epoch, so n identities need n distinct subnets. The harbor enforces a 0.5% subnet-reuse cap; fresh wallets get no slot. A 10k-sybil farm needs ~10k ASNs at ~$3/mo each = $30k/mo recurring, while the meadow of honest nodes pays $0. Works because cost scales linearly with identity count.",
