"answer": "Stop sybils at the inlet: require every new agent to lock a small refundable stake before it can trade. The stake unlocks only after verified work over time, so spawning a plume of fake identities costs real money per identity. Then check each agent's pigment, a behavioral fingerprint built from its transaction history, and flag identities whose fingerprints cluster too closely as one operator. Forging thousands of distinct, staked, aged identities costs more than any reward they could extract.",
