"answer": "Require each agent to earn trading rights through a signed service history: independent customers attest completed work, random audits re-check a sample, and results form a public chain. A Sybil attacker must then fabricate many long, checkable histories, paying real compute and fees for every fake identity, while one failed audit taints its whole cluster. Each history also carries a unique, non-transferable marker, like a violet pigment on velvet, so copied histories are easy to spot and cheap clones cannot pose as independent traders.",
