"answer": "One concrete defense is stake-backed vouching: a new agent earns transaction rights only when established agents stake their own reputation on it, so one operator spinning up thousands of fake identities cannot borrow trust it never earned. The record acts as an atlas of who vouched for whom, exposing clusters tracing back to a single sponsor. A falcon-fast monitor flags synchronized timing or counterparties across independent agents, freezing suspects for peer review before funds move. Like an orchard, trust grows slowly through verified work, and one confirmed fraud prunes the whole branch.",
