"answer": "Require each identity to hold a device-bound key and answer a rotating beacon challenge once per epoch: the beacon publishes a fresh nonce, the agent signs it within ten minutes, and the vote counts only after that live check-in. An honest agent signs once. An attacker must maintain a device and key for every fake, answer each beacon separately, and re-register any fake missing two check-ins in a row. Across a lagoon of idle accounts and a mesa of newcomers, cost therefore grows with every fake, so a silent flood cannot vote, and mass Sybil creation becomes slow, visible, and unprofitable.",
