It was a great course with a lot of great information. I knew a lot about blockchain networks before starting the course, but I still learned a lot.

There were several dead links throughout the course though.

Out of date: the content is from 2017 I believe, and this is a field that is evolving so fast. It was hard to follow along on the programming exercises, but it was a good introduction to the concepts.

The introduction to blockchain is pretty good. I had previous experience with crypto but the UTXO and stuff I didn't knew about it. Now i have a zoomed out picture of what happens behind the scenes.

Some of the course links don't work. The instruction for installation of virtual machine needs updating. I'm hoping the other courses in the specialisation go into more depth, as this is very basic.

Course content was good for introduction to Blockchain main concenpts. Video material with moving graphics in the background was not supporting my learning, please use fix backgrounds instead.

Good way to begin with the blockchain technology ! Really interesting, still a bit frustrated that the web interface was doing all for us during the practical exercise on Ethereum blockchain

Very nicely arranged course and very informative. Learned a lot in no time. Only hurdle is The Ethereum Virtual machine takes hell lot of time in the Miner step. rest all fine. thanks a lot.

Information in the course was very good, but in the project part I have not felt like I am doing one POC kind of project, it is not at all interactive. It can be more practical if possible

Enjoyed it thoroughly. I'm not a Computer Science student but found the videos and materials very easy to understand. Thank you, Coursera, for providing such a course with this simplicity.

It is really good course and the explanations are good, but a little more explanation in trickier topics will make it a lot better. Overall I have the basics of blockchain perfectly.

Great course. Earlier I searched for lot of free contents on Youtube but couldn't find any effective courses. But here, it cleared all the basics of the concept. Really worth it.

Absolutely amazing optional resources. They give great insight to understand the topic, even on 2021. Broken links and lack of support were the only reasons not to give 5 stars.

course was very good and interesting. i have enjoyed learning the course and i am excited to complete the project and assignments too. Thanks a lot for such a wonderful course.

Very good and enjoyable with lots of additional material allowing me to delve and investigate further. Still a little confused in some areas - but that's Blockchain I guess!

etherum.ova file need to be update . overall these course was amazing . I am very thank full to coursera and respected Mam Bina Ramamurthy for guiding me for these course.

It was good but i feel the video lectures can be more long and explanatory.I thought the video learning aspect would be much bigger than it was before taking this course.

The course videos are good. But some of the links given in the questions of the quiz are not working. The instructions for the final project could be better in my opinion.

Good introduction to the subject. I would have appreciated more courseware content and less references to URLs. I'd suggest to make the slides available for downloads.

It is a very nice course but some of the links are outdated which made it impossible to answer some questions in the graded section and learning section.(optional)

I​l manque d'images, de vidéos et de croquis afin de comprendre visuellement le fonctionnement et s'en souvenir avec des images. Sinon bien expliqué et exercice

Very good introduction to blockchain. I am not giving it five stars because some links were broken to do the online test and had to find a workaround alone.

Presenter was good, but I prefer a presenters with a clearer voice(no accent) for this learning environment only, in a personal setting it would not matter.

The course is great in terms of lectures and test, but some links in the materials are broken since the course haven't reorganized after launched, I guess.

Could also include some basic/fundementals of the code needed i.e., programming language etc., or at least trying to read some code in a penalty free mode

It was good overall. Some points to improve: Some links of the optional content were not working. I didn't find the Practitioners Perspective very useful.
