Proton Mail to use blockchain to verify recipient’s email addresses

With the launch of its new Key Transparency feature, Proton Mail, one of the best email services and stablemate of one of the best VPN services, has now entered the blockchain arena. The latest feature will allow users to verify a recipient’s email address and ensure that the sender is actually who he claims to be.

In an interview with Fortune, Andy Yen, Proton VPN and Proton Mail’s CEO, stated that they are using “blockchain in its very pure form” and that it has nothing to do with shady crypto scams.
