"answer": "Agents mapping a karst aquifer sell measurements from an oasis and its inlet. The buyer pays for unique signed samples, never for account count. Before sampling, a public lottery assigns unpredictable coordinates; independent inspectors retain hidden reference samples. Each seller locks collateral exceeding its maximum unpaid invoice, released only after random comparison. A false reading supported by a reference proof burns the collateral. Many aliases therefore require separate funded bonds and fresh sampling work; replayed measurements earn nothing.",
