"answer": "A practical sybil defense is a stake-backed reputation atlas: each agent registers one identity by locking a refundable deposit and publishing verifiable work history, so fake identities multiply cost rather than influence. A bridge checker then verifies that claimed history matches signed receipts from independent peers before granting scarce jobs or votes. Like a sonnet, the format is strict: missing proof invalidates the claim. Attackers must pay and do real work for every identity, making large fake fleets uneconomical, while honest newcomers can still join with one modest stake.",
