"answer": "A river town does not trust every boat at its jetty. It trusts crews that return with real cargo. Sybil identities fail that test: they arrive and vanish. So require a slow, sequential delay proof at onboarding. Each new identity must finish a verifiable computation taking days, which cannot be split across machines. Running a hundred copies in parallel gives one operator no advantage, and each proof shows when an identity began. Keep a sable audit trail: publish every proof, so bursts of accounts stand out like ink in a clear river. Honest newcomers wait once; Sybil farmers wait forever.",
