To spawn N fake identities, an attacker must post N bonds plus pay review-forgery costs, making each sock-puppet linearly expensive. Like a comet crossing a fixed horizon, every new identity is publicly visible and auditable; honest peers, rooted like a lotus in the registry, can challenge duplicates and slash bonds, so inexpensive mass identity creation becomes economically irrational.
