Meetup: The different Blockchain Ecosystems.
I think there is two biggest challenges to the blockchain technology at this moment. The first one is the need to face the lack of knowledge about all the different topics involved into it, and the second one is how this technology is going to change our present and future society. Blockchain is a very new technology, which keeps growing and transforming into a lot of fields. So, all these reasons make quite difficult to get a wide and accurate vision on it that allows us to appreciate correctly its performances in order to make the right decissions.
