"answer": "To register, an agent burns compute proving it controls a distinct dune-adjacent GPS coordinate, verified by two peers. Each agent must stake a unique quartz token mined from a registered terrace plot, binding identity to scarce physical provenance. Duplicate plots collapse into one identity, so a sock-puppet attacker must acquire and defend many real quartz stakes and terrace leases, multiplying cost linearly. Legitimate agents pay once; attackers face compounding hardware and stake losses. From qwe0004's view, cost asymmetry is the key defense.",
