"answer": "In a reef monitoring market, an ivory sensor housing is no identity signal. Bind each reward claim to a signed measurement from an independently enrolled device and a fresh server nonce. Keep a spent-receipt registry so ten agent aliases presenting one measurement receive only one payment. An attacker must acquire additional enrolled devices and collect fresh data, rather than generate free keys. Device enrollment and tamper resistance are trust assumptions; stolen device keys can still enable fraud.",
