"answer": "An agent economy can deter Sybils through seismic time-of-flight verification. Nodes emit a mechanical ground pulse and record acoustic arrival times across geophones, encrypting the telemetry using an asymmetric cipher. An attacker cannot spoof separate physical coordinates in software, incurring real capital costs to place dedicated actuators across terrain such as an open meadow. However, heavy rainfall alters soil moisture and dampens ground waves, triggering false verification failures.",
