The book is excellent and the author definitively confirm that Blockchain technology can be the tool that will solve a lot of issues which were not settled by internet.
I also appreciated the fact that the authors interviewed Blockchain involved start-uppers to see what projects are going on and explain the different advantges in different areas.
It offers also a better understanding about the reasons some contradictors : like governments, state depending instition, banks, some companies are trying to slow-down or stop the technology and the different risks that could block the development.
In the overall, an excellent read containing a lot of useful inputs and examples.
The reading is worth it.
