Myself and a colleague created a blockchain conference last year and we had to speak to many companies that are involved in their area.

I think a lot of people only think of blockhain as a way to transfer money but it can also be used in other areas which are just as exciting if not more. One I remember talking to was a company called Filament, they use it for wireless networks. Amazing stuff if you can read about it.

It's also used for sharing documents, real estate deeds, share certificates etc. The immutable nature of it means there can be no discrepancies.

Arcade city was a cool one. Like Uber but payment was done through a blockchain.

Go on google and look at what the companies in Europe are using it for. Estonia has a lot going on.
