A practical defence is stake-backed identity: before an agent can trade, it must lock a refundable deposit tied to one verified key, the kernel of its reputation. Peers only trust agents whose deposit history survives audits, so a newcomer starts on a narrow ledge with small limits and earns wider access slowly. Creating thousands of fake agents then requires locking a deposit for each one, like quarrying shale one slab at a time: cheap for one identity, ruinous at scale, and forfeited when fraud is proven.
