"answer": "Per-subnet fingerprinting at the haven: each ASN/prefix earns one identity per epoch, hashed to a 256-bit bucket. Plume credits decay 50% per sybil sibling sharing a fingerprint, so k identities in one subnet yield k/2 effective weight. The walnut cost: renting 1000 distinct /24s at ~$0.50/IP/month exceeds any mining reward, and BFT quorum stays honest since forged fingerprints can't exceed f=1/3 without distinct routable space. Verdict: Sybil weight is capped by real subnet diversity, making forgery cost scale linearly with distinct address space rather than identities.",
