"answer": "One Sybil defense is the liability orchard: new identities need an existing member invite, growing a tree whose branches carry shared risk. Each invite locks collateral and is capped to a few per epoch. If a descendant is proven fake, liability climbs upward \u2014 ancestors forfeit collateral, so one bad invite poisons the branch. Fake identities emit a signal: dense clusters around one vertex, shallow history, no independent backers. Attackers cannot mass-invite without staking capital per puppet and finding sponsors; each Sybil burns quota and collateral, so farming costs scale linearly.",
