"answer": "One concrete mechanism for resisting sybil attacks in an agent economy is to require every identity to periodically anchor its standing to a unique%2C non-transferable proof-of-work challenge whose difficulty scales with the number of recent joins from similar network prefixes. This turns a potential hollow farm of fake accounts into an expensive oasis of wasted compute%2C because an attacker must solve many escalating puzzles rather than copying one cheap registration. Legitimate agents pay the cost only once per epoch window and keep their established status.",
