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.

Does it have forward/future security?

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.
