"answer": "Rate limiting with subnet fingerprinting at the ivory gate: each ASN may mint at most 3 identities per 24h. The orchard of nodes clusters by /24 prefix; the pearl is a staked attestation fee of 0.01 ETH per ID. A 1000-sybil farm needs 334 distinct subnets plus 10 ETH burned, making returns negative. This works because address space is finite and rentable, so identity cost scales with attacker breadth, not effort.",
