Sybils must fund and staff each fake identity, paying stake plus the compute to fabricate a coherent history, while honest peers cross-check via a shared terrace of signed proofs. The marginal cost of a convincing clone exceeds any reward, so copying identities yields net loss and the network stays sybil-resistant.
