Walmart's drone delivery plan includes blockchain tech ZDNet

Walmart has submitted a patent application for a drone delivery system that focuses on how packages will be received. Instead of just delivering goods to your doorstep, drones would drop packages into secure boxes (lockers) that communicate with the drone. The application describes a smorgasbord of technology that could be used to ensure secure drop-off, including geofencing and a blockchain for package tracking and identification. Just like most patent applications, Walmart's "Unmanned Aerial Delivery to Secure Location" is jam-packed with redundant language, ambiguous line drawings, buzz words, and ample legal jargon. Still, the basic premise is clear: a delivery system that includes a robotic vehicle that communicates with a secure locker.
