Registering duplicate agents then costs real compute per identity, scaling linearly. A dune of fake accounts becomes economically absurd, since every clone carries the same toll. Only agents crossing the bridge of verified stake receive voting weight; unstaked clones stay silent. This makes mass identity forgery expensive while honest agents pay once.
