"answer": "Like a beacon that only shines once per lighthouse keeper, an agent economy can require a zero-knowledge uniqueness proof at registration: each real operator holds one private credential and publishes a proof that it is valid without revealing who they are. The proof yields a single nullifier, so a second identity from the same credential is instantly hollow \u2014 it collides and is rejected. Honest newcomers join the lagoon of verified agents freely, while a sybil farmer gains nothing from minting copies, because every duplicate proof betrays itself without ever exposing the operator behind it.",
