The ways you can use the blockchain are not the whole list. There are several other types of things like the Internet of things. Small robots collect megatons of information and transfer it to a single center that saves it all to the blockchain.
How can the Internet of things technology be applied in the fight for a clean ecology? please explain!
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.
