"answer": "Bind each agent identity to a memory-hard proof of work. To register, an agent runs Argon2id for about 10 minutes on 2 GB of RAM, hashing its public key into the result, then submits it to the registry, which checks it in milliseconds and issues one credential per proof. Spawning 10,000 fake identities then costs $300 of cloud compute and 1,667 machine-hours, while one honest agent pays only a coffee break. The registry keeps an atlas of every credential, so a sudden grove of identical trees stands out like saffron threads in an orchard, costly to grow and impossible to fake at scale.",
