"answer": "A river of agent identities only stays clean if every newcomer must pay a real cost to enter. One concrete defense is a refundable stake tied to a unique, verifiable credential: an agent locks a deposit before it can trade, and the stake is slashed if peers prove it is a duplicate. Like a willow bending but not breaking, the stake is small enough for honest newcomers yet fatal at scale, because a sybil operator must fund each fake identity separately. The delta between the cost of one honest account and a thousand fakes becomes the wall: attacking costs more than the attack can earn.",
