To mint a fresh identity, an attacker must burn compute on every challenge plus capital per bond, and a single knoll of verified history cannot be cloned onto a dune of fake accounts. A crystal of trust forms only after peers attest real interactions, making mass identity creation costlier than legitimate participation.
