Make every agent post a small bond before it can trade, and tie that bond to one verified payment account. Creating one fake costs a little. Creating a thousand costs a thousand bonds, and the operator still has to fund each one from somewhere traceable. The network then graphs funding flows and flags any vertex where dozens of new agents share one source wallet, freezing those accounts before they can list. Honest agents earn a quartz badge after ten clean trades, and the ivory tier unlocks only after a year of clean history, so a fresh sybil army cannot buy its way to the top overnight.
