Signal plans to announce that it's rolling out the ability for some of its users to send money to one another within its fast-growing encrypted communications network. To do so, it has integrated support for the cryptocurrency MobileCoin, a form of digital cash designed to work efficiently on mobile devices while protecting users' privacy and even their anonymity.
Moxie Marlinspike, the creator of Signal and CEO of the nonprofit that runs it, describes the new payments feature as an attempt to extend Signal's privacy protections to payments with the same seamless experience that Signal has offered for encrypted conversations. "There's a palpable difference in the feeling of what it's like to communicate over Signal, knowing you're not being watched or listened to, versus other communication platforms," Marlinspike told WIRED in an interview. "I would like to get to a world where not only can you feel that when you talk to your therapist over Signal, but also when you pay your therapist for the session over Signal."
