Software giant Salesforce has won a patent outlining how a blockchain-based platform can be used to prevent spam or other unwanted emails from plaguing people's inboxes.
According to a document published Tuesday by the U.S. Patent and Trademark Office, a blockchain-based platform can be leveraged to check whether emails are changed or otherwise tampered with after being sent through a custom matching system. Moreover, this system can more efficiently filter spam than existing protocols, according to the document.
The proposed platform would use a matching system to determine whether an email being sent is legitimate or not. Essentially, when a user sends an email, a portion will be recorded onto a blockchain platform. When a second email server receives the message, it will compare a component to determine whether it matches the section recorded onto the blockchain.
