Definitely, I have to say it must to be updated. Used softwares are so old, many of source links are broken, so then I struggled and spent much time to figure out and fix the incompatibility myself during the course.

Its difficulty is set to intermediate though, contents are so basic. You can't use the skills in real world right after this course. But,

Despite all of these shortcomings, the reason why I gave this course 5 stars, if you are really on the first step to blockchain world without any knowledge, you will learn all of the basic concepts of blockchain in this course. Be patient. After complete this course, you can understand almost all of the articles and words of blockchain.

Obviously, this lecture doesn't make you an expert but, it makes you prepared one to dive into blockchain world.

PS. Though I have poor English skills, there is no difficult to understand all of your words. Thank you.

The curse has to be updated. The instructor starts the demo without much introduction to what she is doing and whether she is using the vm or in the windows. Question #9 on week 4 quiz seems wrong. I noticed that so many students have complained about it and still there is an issue. Coursera should take responsibility to update these errors.

Thanks Bina for a great introduction to Blockchain technology. I liked the way the course is structured, moving from more heard-of concepts and terminology to relatively advanced concepts. The course has definitely provided me with information to explore this technology further!

Excellent beginners overview of Blockchain with a hands-on project on IPFS, which makes you understand the underlying ideas behind the technology.

This course was "ok" in my opinion. Its really a shame that Coursera does not have quality checks running to ensure course material provided in their courses are up to date. Throughout the entire specialization, many links where non-functional since resources where not available anymore. Nonetheless, the course provides a solid foundation for learning more about blockchain technology, in my view.

I​nformation in this course is seriously dated.

With effective and efficiently covered important platforms. I got sufficient knowledge to explore platforms in deep. Big thanks to Buffalo University and Coursera for this specialization course.

Excellent course. This course open your mind to de blockchain universe and how it can be applied to solve problems

This course is very dated. While many of the concepts are still relevant, many of the details are not. Grid+ is out of the energy business. Augur is not available in the U.S. and appears to have shifted their focus to sports betting. Bitcoin has not increased the block size, Ethereum has not moved away from Proof of Work. Hashgraph hasn't be widely adopted. Interplanetary File Systems is still an Alpha release. IPFS also has enough changes to its commands and UI to make completing the final assignment challenging.

Not as useful as the other courses in the specialization which were first rate

Desactualizado

Filled with technical problems, poor instructions, half-baked explanations, poor writing and typographical errors. The videos are far too short and superficial. I managed to pass without being able to do the programming aspect -- nothing in the programming exercise platform works. I regret taking this course. I wanted to complete the whole specialization, but could not complete the DAPP course programming , again because nothing on the course programming platform works properly.

I always wish to find such a platform, where i can test my skills.

And i am surprise to know coursera has all the functionalities and courses i was looking for.

i really enjoyed synchronizing my knowledge with a professional certification.

Excellent hands-on course. What was problematic though was that some of the links are outdated and required some Googling.

That made it possible for me though to appreciate the dynamic nature of this domain.

Simply superb. I haven't found this much detailed account of Blockchain Platforms or Blockchain anywhere else on Coursera. Not even in the courses from some of the leading universities of the world.

I think the course was very well planned. The videos were short and crisp. I also liked the additional reading material suggested which greatly helped understanding the detailed concepts.

This course give me widely see the application of blockchain beyond Bitcoin/ETH that I may not realised before.

Learnt about IPFS and Hashgraphs . The exercise on IPFS was exciting

Well structured course. Enjoyed learning!

Excellent Course. Love this one.

very detailed and helpful

very informative course

Excellent Course

Course is nicely organized and gives good overview of blockchain related technologies. However the world of blockchain is evolving very quickly so many part has to be updated at least every year (e.g. IPFS). From other side there are technologies that create some hype, but won't last long or won't have long lasting impact, thus it seems doubtful to include these topic in the course. Overall I enjoyed the course and can recommend it to quickly get into the field.

A lot of material got cramped into Week 4. A more balance work load would be better.

The course would benefit from more (animated) visualisations on the Hashgraph rather than speech only. Also, please add an exercise involving Hashgraph.
