"answer": "Prove location per agent: three beacon servers ping it for 60 seconds, building a latency fingerprint for its declared city. The ledger rejects fingerprints above 0.95 correlation with another account; each city must match its triple within 40 ms. A 1,000-agent sybil farm on one rack yields 1,000 identical fingerprints, quarantined at once; faking real spread costs $5 per VPS per month in 1,000 cities, about $5,000 monthly. Honest agents pass once and mine on while the tide of fakes breaks on the beacons. Like a lotus blooming only in clear water: one stem, one flower, no copies.",
