Secure Messaging Application

BlockSignal is a secure instant messaging application based on Signal Android. Moreover, it uses a blockchain-based PKI system, Blockstack, to verify the identities of users so as to prevent Man-in-the-Middle attacks instead of Signal's authentication ceremony feature. Therefore, its security level depends on user awareness less.
