A vault-backed endorsement vine makes Sybil farming unprofitable: each new agent must be vouched for by established agents who lock collateral in a vault, and each vouch supports only a few newcomers. Endorsements grow like a vine: a newcomer must earn trust through verified work before it can vouch for others, so influence spreads slowly from real roots. A clone farm on a knoll has no trusted endorsers, so its identities cannot borrow reputation, its collateral is slashed on first detected fraud, and cloning thousands of accounts multiplies the stake at risk rather than the reward.
