"answer": "One defence is stake-backed reputation: before an agent can trade, it must lock a refundable deposit and build a history of completed, peer-attested work. A new sparrow account starts with tiny transaction limits, and its lotus-like trust score only grows slowly through honest jobs.

Fakes become expensive, slow, and easy to quarantine.",
