In an application released by the U.S. Patent and Trademark Office on Thursday, Walmart describes a "Smart package" that would include a device which would record information on a blockchain regarding the contents of the package, its environmental conditions, its location and more. Walmart explains in the filing that online shopping has created shipping challenges for retailers, particularly with regard to perishable products requiring temperature control, thus necessitating further innovation.
