I discovered Wire a few months ago and have been impressed with its feature set. While Wire states that it is using axolotl ratchet, note that it is not the same as the Signal protocol used by Signal. Apparently Wire took the axolotl ratchet (the one Signal started with) and created a custom version for its own use. Moxie stated something of this sort in a comment recently on HN. There have also been some conflicts between Wire and OpenWhisperSystems (searching the web, in addition to reading up on Wire's site, will show you different sides of this).

To avoid confusion about axolotl ratchet and its usage, OpenWhisperSystems changed the name of the protocol used to Signal protocol in March. [1]

Thanks for the response. My sense from the information is that the protocols are extremely similar, the implementation is the primary difference.
