New private messaging app claims to be decentralized and quantum-resistant
The new private messaging app called ‘xx messenger’ has been developed by renowned cryptographer David Chaum and it claims to be quantum-resistant.
The messenger claims to be quantum-resistant, making it able to shield message content from all currently known decryption efforts. This would protect sender, receiver, and their location data from being intercepted or tracked by unwelcome interlopers.
The app is now available on both the Apple and Android app stores.
Quantum resistance refers to cryptographically securing data from even the most elaborate conceivable code-cracking systems. Quantum computers could potentially be used to decipher encrypted messages on other messenger apps, but quantum resistance theoretically removes that possibility from xx messenger.
David Chaum is renowned for making the first known proposal for a blockchain protocol in 1982. He also developed ecash, an electronic cash application that protected a user’s personal information cryptographically. It was widely viewed as a precursor to Bitcoin (BTC).
Chaum told Cointelegraph today that the security of xx messenger relies on a “decentralized mixnet protocol” which “ensures that even the most determined cannot tell who you are talking to.”
The new messenger’s cryptography is open source and can be found on its GitHub page.
The private messaging app also claims to boast a globally decentralized network of 350 nodes. Chaum said:
Node operators earn xx coins as rewards for running nodes on the proof-of-stake xx network.
Other private messaging apps include Signal and Telegram. Each of those apps claims to approach user privacy with a great deal of care by utilizing end-to-end encryption or client-server encryption respectively.
End-to-end encryption is
