U.S. Postal Service or USPS has filed a new patent that will use Blockchain technology to make mail-in voting a safe alternative to physical polling stations. This decision was taken after Trump's concern over the mail service's funding as part of his fight against mail-in voting. As per the patent filing, “this development relates to a voting system that also incorporates the use of cryptographic elements, such as blockchains, as are used with cryptographic currencies, to track and secure the vote by mail system.”
