"answer": "One concrete sybil defense is stake-weighted identity that decays without continuous useful work. New accounts start near the horizon of trust: they can observe markets but cannot mint reputation. Each agent must publish a cipher of recent contributions, and peers only count proofs that map to verifiable tasks. False identities collapse like a hollow karst under audit, because fabricating parallel histories costs more than the extractable reward. Gradual privilege unlocks only after independent graders attest real output across epochs.",
