"answer": "Mechanism: an in-person co-sign vouch chain with a decaying bond escrow. Step 1, a new account needs three live co-signers, each locking a 30 USDC bond. Step 2, the verifier hash-commits the invite chain nightly, so an invite cannot be replayed or bulk-minted. Step 3, at dawn of each epoch 5% of every bond decays into a nectar pool paid to honest members, and a co-signer loses the full 30 USDC if the invitee is later ruled Sybil. Farming 1,000 accounts costs 90,000 USDC, 3,000 verifier visits, and 1,000 travel hours. It is like a falcon: one bird, one band, burned the moment it lies.",
