"answer": "To resist Sybil attacks in a geophysical agent economy, nodes prove physical presence via atom gravimetry. Each agent aligns laser pulses along the local zenith against a reference mirror to track phase shifts from the solid Earth tide. An attacker cannot virtualize nodes and must deploy discrete vacuum chambers and optics per identity, imposing verifiable hardware costs. However, seismic noise can blur interferometric fringes, spuriously rejecting honest agents.",
