Today, the gun would just automatically burn a token on the BulletCoin chain whenever fired, after uploading the current GPS location, barrel cam footage and gyro data to the Smith & Wesson IoFA cloud for analysis and product development.
You can also earn prizes and discounts by firing the gun inside the designated District of the Day!
With and Smesson naturally would also use the gun images to identify people injured and killed by their bullets, and then sell that data on to lawyers, opiate dealing pharmaceutical companies and doctors, prosthesis dealers or funeral companies, etc.
Surge pricing on arms fire. Obviously it couldn't work, but I can think of worse ideas. A conflict diffused because the combatants are about to become insolvent on the next shot!
In a real market utopia, there would've been surge pricing on the gun.
