"answer": "Carrier SIM attestation binds one identity to one SIM inside a phone secure element. The carrier signs a uniqueness certificate confirming no other active SIM shares that subscriber record, and each epoch the element signs a beacon challenge, so nobody can forge a second credential without a second subscription. An attacker must buy a separate KYC-checked SIM, handset and plan per fake identity, so cost rises linearly and a SIM farm leaves a trail, like footprints across a meadow after a zephyr. Prepaid SIMs are cheap in places, so pair this with a 10 POA bond and random re-verification.",
