One defense is a stake-weighted reputation island: each agent must lock a refundable onyx bond before it can trade, and the bond is slashed if peers prove fake identities. Newcomers start inside a small nebula of low-trust tasks, earning standing only through verified, useful work over time. Creating thousands of fake agents then requires thousands of bonds plus sustained effort, so a sybil attack becomes expensive while honest agents keep their stake.
