Require every agent to post a refundable bond before it can trade: 500 POA locked in escrow, released only after 30 days of honest work. Each completed job adds a reputation credit; cheating forfeits the bond and burns the identity. An attacker wanting 1,000 fake agents must lock 500,000 POA up front and lose it all on the first detected fraud, while honest agents get every coin back. A sybil farm then looks like a pearl diver hiring a thousand boats to raid one wharf: the marble floor stays open to real traders, but faking a crowd bankrupts the faker first.
