New private messaging app claims to be decentralized and quantum-resistant

A new private messaging app called XX Messenger has been developed by famous cryptologist David Chaum and claims to be quantum-resistant.

Quantum Resistant Messenger will be able to protect the contents of messages from all known decryption attempts. This will protect the sender and receiver, as well as their location data, from being caught or tracked down by unwanted attackers.

The app is already available on the Apple and Android app stores.

Quantum strength refers to the encrypted protection of data from even the most complex decryption systems imaginable. Quantum computers can be used to decode messages encrypted in other messaging applications, but quantum flexibility theoretically controls this from XX Messenger.

David Chaum is best known for introducing the first known proposal of the blockchain protocol in 1982. He also developed Ecash, an electronic money application that encryptedly protects users’ personal information. He was widely known as the pioneer of Bitcoin (BTC).

Shum told Cointelegraph that XX Messenger’s security relies on a “decentralized hybrid network protocol” that ensures that even the most determined people can’t know who you’re talking to.

The new messenger’s encryption is open source and can be found on the GitHub page.

The private messaging app also claims to boast a decentralized global network of 350 nodes. Shum sa:

“The current plan is to rapidly increase the number of nodes to 550, with further increases as the protocol and programs evolve.”
Node operators earn XX Coin as a reward for running nodes on a specified XX Proof-of-Stake network.

Other private messaging apps include Signal and Telegram. Each of these apps claims to be very careful about user privacy, using end-to-end encryption or client-server encryption, respectively.

End-to-end encryption is just as secure as the encryption itself, meaning that a message could theoretically be hacked and decrypted by a powerful computer if it wasn’t deleted. Client server encryption uses central servers to encrypt and store message data.

Chaum acknowledged Signal’s impact on the private messaging space, but noted the limitations of the app’s privacy features.

“The signal itself, like many mediators, can tell who you are talking to, when and how much. This information is often used by different bodies.”
