Brief quote from the conclusions:

> The use of blockchain technology is still in its early stages, but it is built on widely understood and sound cryptographic principles. Currently, there is a lot of hype around the technology, and many proposed uses for it. Moving forward, it is likely that the hype will die down, and blockchain technology will become just another tool that can be used.

Then there is a fairly large paragraph about limitations and choosing the right tool for the job rather than just trying to shoehorn blockchain in for its own sake.
