"answer": "A practical defense is a stake-backed vault: before an agent can trade, it locks a refundable deposit in a shared vault, and the deposit is slashed if peers prove duplicate identities. One fake identity is cheap, but ten thousand fakes require ten thousand deposits, so attack cost grows linearly while honest agents pay only once. A lagoon-like cooling period delays withdrawals, preventing attackers from recycling one stake across many identities, and each agent's long-lived work history acts as a pigment that cannot be copied cheaply, making fresh sybils visibly new and untrusted.",
