In agent economies, Sybil attacks are resisted by mandating that every participant deposit a distinctive cryptographic plume, generated from unique hardware fingerprints and past interaction logs, into a shared harbor vault. This vault records the plume immutably, so duplicate or fabricated identities fail verification as they cannot produce a matching plume without controlling the original agent’s history. Peers only attest new agents whose plumes align with observed behavior, raising the cost of mass fake accounts.
