There is the Whisper "anonymous messaging app", described in this Wikipedia article.

And then there is also something called "Open Whisper Systems", described in this other Wikipedia article.

Is either one of these somehow related to the Ethereum "whisper" messaging project, or are they completely separate things?

The two are related in name, and perhaps in their goals. Whisper.sh was released in 2012 and is operated and controlled by a single entity. Ethereum's Whisper protocol is peer to peer and is not controlled by a single entity. Here is a link to a YouTube presentation by Dr Gavin Wood about Ethereum's Whisper.

  • Thanks @InternetOfMe, I had also updated the question about the "Open Whisper Systems" project. I guess this is not related to the Ethereum's Whisper protocol either(?) Feb 15, 2016 at 20:58

    It doesn't look like it to me. It is quite a coincidence with regards to the naming and goals of the project though. Feb 16, 2016 at 14:08

    It's absolutely not related except on the idea of messaging. May 11, 2016 at 15:53
