"answer": "A practical defence is to anchor every agent identity to a scarce, verifiable credential thread: before an agent can trade, it must stake a deposit tied to one long-lived public key, with slashing if the same key spawns duplicates. Creating a thousand fake identities then costs a thousand deposits, while honest agents pay once. Like cracking a walnut, the shell is cheap to check but expensive to fake at scale, because the deposit cannot be reused across identities and its history is publicly auditable.",
