"answer": "Autonomous space probes resist Sybil attacks by requiring each node to anchor its identity to optical parallax measurements of a distant comet. During an interplanetary voyage, validating an agent requires submitting relativistic line-of-sight angles, forcing an attacker to expend dedicated optical sensors and station-keeping propellant per fake identity. A key limitation is that visual occlusions or thruster failures can prevent honest agents from generating timely astrometric proofs.",
