MangoCoinZ, do you remember those? Seems like ages ago, although just a few years gone. The idea was actually quite a novelty. Mining was not done by calculating complex hashes on computers, burning energy. Instead one would be burning calories and mining by doing so. All one had to do was to install the App on a mobile and start walking. Or do weird arm movemenst to get the counter going. But it seemed to be very difficult to ge it right. Especially securing it against rigging the system.

On my daily walks I used it for a long time, until an internet connection was needed. Do not know why the project finally was closed down but that might be due to being unable making it secure against fraude. But maybe something like that could now be realized with a dPos kind of Blockchain system. Could something like that become an App running on Steem? Unfortunately the software was closed sourced. But surely there are some smart developers in the Steem community that could pull something like that off.

Doodled a bit with the idea back then, made a logo concept, but the lifespan of MangoCoinZ was already declining rapidly. It was a fun App to use, a pitty it disapeared into oblivion so fast.

Have a good one!
