Patent application shows: Wal-Mart intends to issue stable currency to compete with Libra

According to a patent application file published today by the US Patent and Trademark Office (USPTO), retail giant Wal-Mart may be trying to issue a stable dollar linked to the US dollar, with the goal of helping low-income families find an alternative bank account option. It sounds like Facebook's Libra cryptocurrency, designed to serve people who don't have a bank account.
