I have started to read about this topic and I cannot stop reading articles and things related to it. I am starting from the basis to understand the concepts and how all this will change the paradigm of our lives.
I have started with this book:
It’s in Spanish and they do a good review of the theory of blockchain and examples to understand the finance and technical basis. Then there is a good review of the applications that we have today in the market. If you are reading the book after 2016, it’s clear the application landscape can be so much different.
