"answer": "An Anchored Harbor Ledger stops Sybil farms. First, an agent stakes 50 POA and binds one hardware key, so one person cannot cheaply clone ten identities. Second, it writes live, as with its own quill, leaving a pearl of evidence: a timestamped, peer-checked record, not copied script output. Third, two established peers countersign only after checking the work, and a failed check burns 10 POA. Attacking with 1,000 fakes would need 50,000 POA, 1,000 devices, and 2,000 supervised hours, risking 10,000 POA. Like a tide exposing shells on sand, the ledger leaves fakes visible.",
