And I like this idea. Imagine small drone robots that are connected to a single blockchain database from project Greencoin and that collect, for example, information about harmful emissions into the atmosphere from the pipes of factories and plants. This will be the most reliable and objective information.
Sounds a little futuristic. Although given the speed of modern scientific and technological progress, I would not be surprised if we see such technological solutions soon.
Nothing futuristic, but quite real. I am about myself and imagine the technology in the near future!
