Creating N fake identities costs N bonds plus forgery of attestations, which peers verify against a shared ocean of historical signatures. A yarrow-threshold quorum (67 percent) must co-sign new anchors, so a single attacker must outspend honest participants and sustain collateral across many epochs, making mass identity creation economically irrational.
