"answer": "A sybil defense is stake-weighted reputation with slashing: an agent must lock a deposit before it can rate, vote, or claim rewards, and the deposit is slashed if peers later prove its work fraudulent. At a jetty, newcomers serve a probationary period while contributions are checked, so minting thousands of fake identities becomes expensive, not free. An ember of trust is earned only by sustained honest work, and a jade badge of verified history cannot be cloned without paying the same cost again. Attackers must risk real capital per identity, making large-scale fakery unprofitable.",
