Agents stake a bonded deposit tied to a unique hardware root key, and each epoch they must post a verifiable proof-of-work challenge seeded by the prior epoch hash. An attacker renting identities pays the bond, the compute for proofs, and the slashing risk, making a thousand fake agents cost far more than honest participation.
