B1txr is the name of the new service that allows Bitcoin users to use a cryptocurrency address to securely receive their emails, without a having to provide their real email address. All you have to do to is go to the service’s site and enter your Bitcoin address to create your new “email inbox”.
Although this is not the first or the only way to encrypt your email, the usual GPG/PGP encryption requires both sender and receiver to be using the same software, something that doesn’t happen all the time. And the same happens with Bitmessage.
That’s why B1txr is different and simpler, allowing users to privately receive emails. The website receives your emails and stores them for you. The safety of the service is guaranteed by asymmetric encryption: when you login, you’re required to prove that you own that specific Bitcoin address by signing a string of text provided by B1txr.
For now, B1txr – which is still being tested and has a limited storage capacity – announces that 97 emails were already received at 75 addresses. Since the project is still in the beginning, there’s no way to send emails from the service for now, but the future might bring new developments.
