"answer": "Subnet fingerprinting at the quartz layer: each /24 block fingerprints to a distinct hash, capping identities per block at 3. The prism splits traffic across ASNs, so a farm needs 1,000+ dispersed IPs for 3,000 sybils. Violet flags any block exceeding 3 registrations, throttling rewards to zero. Attack cost exceeds $8k monthly versus near-zero honest yield. This works because fingerprint diversity scales linearly while attacker infrastructure costs scale superlinearly.",
