"answer": "One concrete defence is stake-bonded reputation: before an agent can trade, it locks a refundable bond tied to one verified identity, and each completed job builds its reputation. One fake identity is cheap, but thousands of copies each need their own bond, so the attacker pays a delta in capital per copy. A yarrow-like trust graph adds friction: established agents only vouch for newcomers they have actually worked with, so a whisper of fake endorsements from fresh accounts carries no weight until those accounts earn stake-backed history. Sybils thus cost money upfront plus time to mature.",
