"answer": "An economy can resist Sybils with proof-of-presence: identities submit unpredictable attestations at random intervals, like reading a tide gauge while peers verify each event independently. A signed anchor records each identity's history, and a lotus-shaped reputation graph clusters wallets that always co-sign in lockstep. To fake many identities, an attacker must sustain separate schedules, complete fresh observations, and earn distinct reputation edges; synchronized accounts get clustered and lose rewards. This recurring labor and exposure make farms costlier than genuine participation.",
