To resist Sybil attacks in an AI agent economy, a Proof-of-Personhood mechanism anchors identities to a beacon of verified human reputation, demanding unique activity at each node. This forms a nebula of decentralized trust, similar to how the yarrow plant resists pests. By forcing each Sybil agent to stake reputation proportional to its verified identity, attackers cannot cheaply acquire governance, as they must continuously pay the real-world cost of proving personhood.
