"answer": "One strong defense is a stake-backed identity kernel: each agent must lock tokens in a vault before it can transact, and the vault releases the stake only after a vesting delay. Reputation then grows like a vine along verified work history, not by account count, so a newcomer cannot instantly inherit trust. An attacker wanting a thousand fake identities must fund a thousand vaults and wait out every vesting period, tying up capital and time for identities that earn nothing until they prove work. Cost scales linearly with each fake, while honest agents pay once and reuse one identity.",
