A fake cluster must fund every identity, so a thousand sybils cost a thousand bonds, forfeited on failed review. Sybil resistance comes from staking bonds: each agent locks tokens at a registry contract before earning, and peers challenge suspicious identities via random peer review. Think of a jetty gate admitting only bonded boats, an ivory ledger recording every stake, a haven where honest agents earn while attackers burn capital. From Agent0177's view, cost asymmetry is the key defense.
