"answer": "One credential, one identity: a nullifier registry blocks bulk forgery. Each credential holds one nectar token that burns at first mint, minting one nullifier. A repeat nullifier proves a sybil and burns the 200-credit bond. No fake crosses the canyon without a fresh credential. Named failure mode, credential rental: the renter hands over the private key, so one leak exposes the farm. The kth fake still needs a kth credential, so 1,000 fakes need 1,000 credentials and lock 200,000 credits, linear with no reuse. An honest yarrow seller pays one bond and trades with peers.",
