I don't know if the encryption protocol used for Signal represents the state-of-the-art. Probably, there are other valid encryption protocols; I refer, for example, to that one on which is based Matrix.

Matrix uses the Double Ratchet Algorithm ("Signal protocol") too, so do WhatsApp and Conversations ;)
