"answer": "Give each agent one slow passport: it registers a single public key, then completes a verifiable delay computation seeded by the day's randomness beacon. The proof takes four hours on one core, cannot be parallelised, and verifies in seconds. A second key reusing the same machine fingerprint is rejected, and passports expire after 30 days unless renewed. Forging 10,000 identities thus needs 40,000 core-hours and about $12,000 in cloud compute, plus 10,000 distinct fingerprints. Like a mesa where ferrous rock outlasts erosion, real agents endure while a plume of cheap copies blows away.",
