One of my passions is teaching, being a TA for the Object Oriented Programming Course during my bachelor studies. At the same time I got my Pedagogical diploma by holding programming courses in high schools. Recently I decided to start a website where I can also share some of my interests.

Good introduction course
By Peter Toth on 11/2/2018
Provided a good overview of the topic overall. Explanations helped me understanding the related concepts, technical constraints and pitfalls. Good introductory course going beyond bitcoin. Dragos does have an accent, but it does not hamper understanability. I had no problem following him even at 1.25 speed. I liked the bits on applacations built on ethereum and the explanations, why blockchain may not be the answer in certain situations. Would have been happy to learn about more real world applications though, where blockchain do actually help solving issues (the course covers some, but a wider overview - or more pointers on literature - would have been better). I was happy with this course and can recommend it as a starting point to anybody interested in blockchain.

The presenter oozes expertise and confidence in his subject matter. I have learnt so much and have to take my hat off to Dragos for the time and energy he has clearly put into delivering a free course that is better than any I have paid for so far! Thanks Dragos! Lisa

This course was a good place for me to learn and start of blockchain world. The presentation was good. It impressed me to learn more about the blockchain, bitcoin and others. This course is highly recommended for new comers by me. Looking forward to release a course for developer in future. Thanks a lot Dragos.

The speaker is very lucid and breaks a complex topic into very basic components. The historical approach is effective. Most importantly, he frames the right questions and proceeds to provide very illustrative examples and responses. The solutions are works in progress. Having just completed the course, I reaffirm my 5 star rating.
By Ivo Lammertink on 5/14/2018
The course is especially useful for people who are getting started with blockchain and crytpocurrencies. For those that are already more familiar with this topic there are some themes covered in more detail than simply the basics. I would suggest a follow-up course in coding languages and specifics of certain applications within the blockchain, such as smart contracts, IoT etc. Thank you for the interesting course.
By Harshavardhan Kalathur on 5/6/2018
It was a very informative course considering that I am a novice. I left this course feeling excited about this technology and would like to give serious consideration for a career in this space. However, I am not a developer and I am not looking to become a miner or an investor either. At this juncture, I am interested to know how this knowledge can be utilized to perform feasibility studies for adopting blockchain, from a business development standpoint. Any pointers on this would be great.
By Rhista Singh on 4/17/2018
I found the course to be very useful and well explained. I liked that there were references to real world events which made concepts a lot easier to grasp. I enjoyed the course and look forward to more in-depth courses on the Blockchain subject.
By Guido Kroon on 2/18/2018
Perfect course that explains a very technical subject, blockchain, in every day language. I highly recommend every newcomer exploring this daunting subject to go from 0 to 60 in less than a few hours using this course!
