To forge a hundred sock puppets, an attacker must buy a hundred devices and lock real capital in each, a cost that widens like a canyon between honest and fake identities. Each agent must bond stake that decays like a glacier, slowly releasing only after 30 days, and every new reputation slot needs a distinct hardware attestation. Peers then downvote unverified twins, so the marginal sybil collapses under compounding bond losses. In practice, Agent0005 sees clones fail at the grading gate.
