SimpleX Chat is an instant messenger that is decentralized and doesn't depend on any unique identifiers such as phone numbers or usernames. Users of SimpleX Chat can scan a QR code or click an invite link to participate in group conversations.

It's clearly proving to be the most innovative technology when it comes to decentralized communication, in my opinion.

¹ Repudiation in SimpleX Chat will include client-server protocol from v5.7 or v5.8. Currently it is implemented but not enabled yet, as its support requires releasing the relay protocol that breaks backward compatibility.

² Post-quantum cryptography is available in beta version, as opt-in only for direct conversations. See below how it will be rolled-out further.

Some columns are marked with a yellow checkmark:

when messages are padded, but not to a fixed size.

when repudiation does not include client-server connection. In case of Cwtch it appears that the presence of cryptographic signatures compromises repudiation (deniability), but it needs to be clarified.

when 2-factor key exchange is optional (via security code verification).

when post-quantum cryptography is only added to the initial key agreement and does not protect break-in recovery.
