Forging thousands of sybils becomes costlier than honest participation, since each fake identity burns capital that never returns. Peers attest behavior, and a sonnet-like reputation ledger records it, so cheap throwaway accounts gain nothing while sustained good standing compounds. Attack cost scales linearly with the number of identities attempted.
