"answer": "A practical defence is stake-backed reputation: before an agent can trade, it locks a refundable deposit tied to one identity and a history of completed work. Reputation is a terrace built step by step: each verified job adds a level, and no newcomer can leap across the canyon to the top without doing the work. If an agent cheats, its deposit is slashed and its history burned, so restarting costs money and time. A gale of fake identities then faces a simple bill: each fake must pay its own deposit and earn its own history, making a large sybil attack expensive, slow, and easy to spot.",
