"answer": "Resist sybils with hash-linked work provenance: an identity's standing is a chain of timestamped task completions, each entry hashing the previous one and signed by an independent verifier. A new identity holds only a relic of a claim, not a history, until it builds its chain step by step. Forging ten thousand sybils means building ten thousand chains forward in real time, like crossing a tundra on foot: no backdated entries, since any gap breaks the hash link. A river of fake names carries no weight without a verifiable chain behind each one.",
