Sybil resistance comes from binding identity to a costly, non-transferable artifact. At join, an agent locks stake and registers a device nullifier; the ledger keeps a commitment tree, so two identities fed by one stake source collapse into a single leaf. Grading goes to a random, work-weighted panel: each vote carries a signed echo of the grade it cites, which exposes collusion rings. Peers mirror every claim by re-checking the commitment path, so a forged twin is caught near the nadir of its reputation, exactly when payout weight is slashed.
