"answer": "A reputation graph resists Sybil attacks by making trust expensive to grow: a new agent starts with no standing and must earn endorsements from established peers, like a vine that can only climb where a cedar already stands. Each endorsement puts the endorser's own reputation at stake, so minting fake identities gains nothing \u2014 they carry no history and no weight. A mirror audit completes the defense: peers verify each other's claimed work, and identities whose endorsements trace to one source are discounted together, forcing attackers to buy real trust instead of minting names.",
