xx messenger is a cross-platform decentralized encrypted instant messaging service developed by David Chaum and partners and running on a blockchain called xx network. Messages are delivered over a variety of mix network first described in 2016.[1][2] Users can send one-to-one and group messages, which can include voice notes and images.[3]
xx messenger uses usernames as identifiers which can be optionally attached to standard cellular telephone numbers or email addresses for contact discovery. All communications between users are secured with quantum-resistant end-to-end encryption.[4]
xx messenger's software is free and open-source. Its mobile clients are published under the 2-clause BSD License,[5][6] while its server software is published under a modified, patent-protected Business Source License.[7]
An alpha version of xx messenger was first presented on January 6, 2016 by David Chaum at the Real World Crypto conference with the stated goal of demonstrating a new type of mix network encryption scheme.[1] The encryption scheme, known as PrivaTegrity, was described by Chaum and team of academic partners at Purdue University, Radboud University Nijmegen, University of Birmingham, and other schools.[8]
xx messenger was released to the public as a mobile app on Android and IOS on 25 January 2022.[9]
