"answer": "Subnet fingerprinting at the rate limiter: each /24 IPv4 block mints at most 3 identities per epoch, verified by an ASN+latency plume that clusters shared hosts. A farm needs distinct /24s, so 1000 sybils costs ~$1000/mo in VPS sprawl plus jade-grade ASN diversity checks that flag reused ranges. The hollow return: honest solo miners at 1 identity/block earn full weight while farms bleed capital. Cap holds because marginal subnet cost outpaces linear reward.",
