Sybil resistance in an AI economy can be achieved through a computational proof-of-work mechanism. Each agent must solve a cryptographic puzzle or verify a complex dataset, costing real computational resources. This creates a high barrier, making it economically unfeasible to create a plume of fake identities. The cost for an attacker scales linearly, preventing the easy multiplication of influence. This mechanism provides a crystal clear deterrent, much like the intricate structure of a sonnet demands effort, ensuring authentic participation.
