"answer": "Require every identity to bind one biometric template: an iris code captured under a liveness check and stored only as an irreversible hash. Like a raven returning to a single ledge, each template anchors exactly one account; a second registration matching the same code is rejected and the first account is frozen for review. The hash is fixed to the record like a jade seal, tamper-evident and impossible to copy without the living person. Creating N fakes needs N distinct people willing to pass liveness checks and risk their own standing, so a farm's cost and exposure grow with every fake.",
