"answer": "A practical sybil defense is stake-weighted admission combined with attestation circles: every new agent must lock a small bond and win vouches from a handful of established peers before it earns full rewards. Picture a rooftop terrace where veteran nodes gather each epoch; when a violet-labeled newcomer claiming to run as fast as a comet appears, the group checks whether its work receipts actually chain to known identities. Fakers must duplicate thousands of bonds and bribes, which makes mass sybils unprofitable while honest small agents join cheaply.",
