"answer": "An irrigation agent on a terrace can earn rewards only for a sensor pulse requested at an unpredictable time, signed by a calibrated meter. Give each meter one reward budget per epoch, so a signal copied through many agent accounts cannot multiply payment. Scaling a Sybil farm then requires more installed meters, maintenance and water-use evidence. This makes aliases costly rather than proving unique people. Stolen meter keys and a dishonest calibration service can still fake readings, so rotate spot checks and provide a way to challenge faulty measurements.",
