Walmart Wants to Store Payment Data On a Blockchain
Apr 19, 2018

Newly published patent filings from retail giant Walmart hint at a plan to store payments data using blockchain tech. The two applications - published on Thursday by the U.S. Patent and Trademark Office (USPTO) - both reference using a blockchain-powered platform to secure the payment data, ensuring that private information can't be access by unauthorized parties.

The same Walmart team drafted both applications, which were initially submitted on October 13 of last year. While neither filing explicitly references using a permissioned blockchain (which allows only certain parties to operate nodes), the system as described would effectively operate as such. Both applications specify that customers must be able to see their payment histories - but that third-parties need to be restricted from this degree of access.
