This is an introductory course to Blockchain. The supplemented material (in other words self-study) is excellent and in my opinion is the only way to master the concepts and details of this discipline

A comprehensive and clear course that summarizes the basic concepts to understand blockchain technology. Also, the resources and contents included are very valuables. I totally recommend this course.

This wouldve been a great course but I had a few problems with it. Compared to other e learning courses I have taken, the text associated with each video IS NOT correct. This is most likely generated by AI and the audio of the video and given the lecturers accent....made it hard to follow along and take notes.
The final activity, did not work as expected and I saw far too many people having issues with this portion...thankfully got through it but this is making me reconsider completing the specialization due to how frustrating it was.

I am trying to dis-enroll. This is a comprehensive course on CRYPTOcurrency, with heavy bias towards Ethereum, NOT Blockchain. The two are NOT the same, by any stretch of the imagination. I am very knowledgeable of both Crypto and Blockchain. I wanted to take a course to learn in-depth nuances of blockchain tech to aid me in learning to code for it.
Again, this is a Crypto-currency course.
All mentions of blockchain revolve around Crypto-currency only.

There ia no support from U of Buffalo for any of our questions and the assignement, that should have been an easy series of steps took me a few days to complete by trial and erro methods. Unnecessarily too complicated due to the lack of support from the course content generators.
I likes the material presented and the instructor very much, but I would not be taking any more from University of Buffalo for this very same reason above.

Don't waste your time with this course. The way the instructor is speaking is like she is reading something. Most of the time waste time. For exmple in 8 minutes video 1 minute she talk about what we will learn and last minute she repeats it. In the middle there is no or so little usefull information. Totally unsuefull.

Broken links + instructions that are out of date. The Virtualbox setup for the final project doesn't even work on MacOS Catalina. Some of the additional readings are absolute garbage - blog type sites without any proofreading and awful grammar. It's criminal to charge $70/month for this content.

The worst instructor ever. This course will teach you nothing. Lessons are worthless, and the only valuable thing is some external links to other materials that actually worth reading. The instructor teaches you nothing and nothing at all. The worst course I came across on Coursera.

This course was completely out of date, and the instructor seemed like reading the text from the screen, and there was no explanation, I have experience in the field of Blockchain, and I would suggest that this course needs a lot of improvement, I was disappointed with the content

The content of the course is great. The final task was not possible to complete as I experienced more than 58, 000 errors on extraction, was unable to find the ovf file (may have been corrupted).
Unfortunately I will have to drop from the course without completing it.

This course is abandonware. It requires using Virtual Box that only supports macOS up to 10.15 which ANCIENT!!! If you are on a Mac, you will not be able to complete the homework assignments. Do NOT pay for this class.

Too little support from the mentors. Several participants, me included, couldn't finish the course due to technical limitations which were not offered to being solved.

The professor is literally reading from a screen in front of her, without explaning a single letter or concept, just like a student loud reading a book in a classroom

Good basic course but unable to complete the final assessment because I am using a Mac with M1 chip. This is not mentioned until you reach the final assessment.

Seriously, dont waste your time with this course, there are other courses in Coursera much better. Better explained, better examples and much more detailed.

as a lot of others students I am very upset with the final test of week 4, I saw the discussions and too many people have my same opinion.

too easy. You can read first several sentences on Wikipedia about Ethereum and Blockchain to find out all information in this course

the course offers a nice very general introduction, but I was expecting also an overview on technical aspects of the topic

Very very basic, providing no coding to do, and nothing that is going to help you remember anything.
