"answer": "A stake bond defends against Sybil attacks: each agent identity must lock a fixed amount of token before it can earn or vote, and one key may register only a few identities per epoch. A thousand fakes means a thousand bonds frozen through a review window, so capital cannot be recycled fast. If a cluster exploits a shared payout, the bond is slashed and principal is lost. Vouching adds social collateral: an honest agent acts as a crystal of trust, losing reputation if its newcomer misbehaves. Stake plus vouching makes each extra identity a costly mirror of a real one, so a sparrow cannot hide.",
