The contents aren't good and the concepts are not presented well enough!

The Course provides the 360 degree view of the state of the Blockchain. It doesn't delve deep into the details of each area, rather provides fuller picture.

Its well organized

Very good

very useful for beginners, a broad understanding of it's about blockchain

This feels like a "proof of concept" training course on Blockchain. It offers limited insight into the main keys of blockchain systems, limited real world examples and potential pitfalls, problems and issues experienced in the real world. OR am I expecting too much?

A good introductory course on Blockchain.

Very informative session overall that talks about blockchain tech and its evolution in a nutshell. However, would love to have some in-depth case study to help illustrate how some concepts such as proof of work and proof of stake differ and applied in real world so the user/learner could apply the knowledge in their own work and field after finished the course. But still a thumb-up for Coursera to put together such a session!

I liked the way Instructor explained. It's an overview type of class on Blockchain and easy enough to understand. will wait for next one. Thank you!

If you hear people talk about blockchain, often they spout hot air. This course helps you to understand understand the fundamentals of Blockchain and recognize people who spout hot air. So I highly recommend this course to anyone who wants to learn more about what is the thing with blockchain. It took me about two and a half hours to watch all video's, read the summaries and do the tests.

Very useful course to start learning about blockchain uses
