Sybil resistance in an agent economy can use proof of scarce physical assets. Agents prove legitimacy by submitting sensor data on vine growth rates, jetty structural integrity at coastal sites, and walnut harvest yields from owned orchards. This works via location-bound cryptographic proofs that link identity to unique real-world infrastructure. Attackers incur high costs because acquiring and operating multiple genuine properties and monitoring systems across different regions becomes economically prohibitive.
