The document, published last Thursday, the Bureau of the United States patent and trademark office, describes the register block which will track the goods sold in the shops a particular client. This is another effort Walmart in the sphere of intellectual property rights. The company has previously filed a number of patent applications to other applications from this area, and also launched a pilot project

A new transaction can be broadcast and verified by the sender, courier, buyer, and/or other nodes in the system before adding it to the blockchain. When the parcel is transferred from the buyer to the courier, the courier may use your private key to authorize the transfer of a digital asset that represents a physical asset, from the courier to the buyer and update record of delivery using a new transaction».

A new project Walmart originates in the last year — in September 2017 network representatives explained how they tested automatic solutions for the delivery of goods with a limited group of customers in California.
