Blockchain and Bitcoin Fundamentals (Udemy.com)
Learn the key elements of blockchain and Bitcoin in this bestselling video course and accompanying PDF glossary.
Created by: George Levy
Last updated September 2026
Our take
Based on the ratings of 47,480 students, a sample of their written reviews and the syllabus, as the course stood in September 2026. No course pays to be reviewed.
George Levy's course is a short, non-technical introduction to blockchain and Bitcoin. It runs about 3.3 hours across 45 lectures, with five quizzes and a PDF glossary. The audience list is blunt that there is no code, so developers who want to build on a blockchain should look elsewhere. Nothing is required to start. Most of the runtime sits in one 149-minute main section, followed by a 37-minute block on getting started with Bitcoin and a short wrap-up of resources.
Reviewers mostly praise the teaching. They describe clear explanations, real-life examples, and a structure that works for someone who knew almost nothing going in. More than 43,000 of the 47,480 ratings are four or five stars, which gives the 4.4 average. The complaints are specific, though. One student found the volume and recording setup changed from chapter to chapter. Another dislikes the promotional pitches between lectures. A third says points repeat and feel vague, and one finished still unsure about mining, how blocks link to transactions, and where the mining reward comes from.
The course was last updated in September 2026, and more than 143,000 students have enrolled. It is paid, but the time cost is small, so the risk is low. Treat it as a vocabulary and big-picture course. It will get you talking sensibly about blockchain at work and leave a newcomer more comfortable about buying a first bitcoin. For how mining actually works, plan on a second, more technical resource.
Pros
- Reviewers say concepts land clearly, with real-life examples, even with no background
- Short at 3.3 hours over 45 lectures, so it fits into a weekend
- Includes a section on buying, using and securely storing bitcoin, not just theory
- Updated September 2026, so the material is current rather than a 2017 leftover
Cons
- Thin on mining and block mechanics; one reviewer still lacked them after finishing
- Audio volume and recording setup reportedly change between chapters
- Promotional pitches between lectures annoy some students, and some points repeat
I knew very little about Bitcoin when I started this course, this course gave me a true understanding of the fundamentals of Blockchain & Bitcoin so that I feel comfortable with considering getting to Bitcoin.
Genuinely beginner: no requirements, no code, aimed at business people rather than developers.
What you will learn
- Have a strong understanding of what blockchain technology is.
- Understand what Bitcoin is and how it works.
- Know and use key vocabulary and concepts commonly used when discussing blockchain and Bitcoin in business situations.

"What I love about the course's lectures is that by the end of each lecture I understood the concept presented clearly. Also, I like the opening of each lecture, it prepares the student, for me it lowered the fear factor when approaching a new concept in Bitcoin Network and Blockchain.
The course doesn't provide only the theoretical part of Bitcoin Network and Blockchain, George Levy provides many examples which delivers the objective of the lesson (lecture).
I truly recommend this course for new comers to Bitcoin Network and Blockchain.
Thank you George Levy for the great course."

It bothers me that each chapter of the course is recorded in different environment and with different volume. It makes it hard to concentrate on the content witch itself is very interesting.
By Olela Ikirezi on 7/2/2026
I love how easy this course explain topics that are often hard to digest and comprehend. Great teacher and even better knowledge being shared.

I will recommend this course to anyone considering if Bitcoin is something that they are considering.
By Alexander Tankelevich on 6/20/2026
The course was beneficial to familiarize myself with bitcoins, blockchains, etc. Thank you to the teacher and Udemy for giving me this opportunity. However, I am not interested to go any deeper on the topic. Thanks again!
By Jayden Do on 5/18/2026
Clear and concise videos, planned structure and scope of course, AI assisted integration into the learning questions for extra information is very good.
By Ivan Fajardo on 5/2/2026
Está resultando muy interesante y de fácil comprensión el contenido. Sugeriría que también pudieran tenerse los subtitulos en español.
By Alain GIRARD on 4/13/2026
After completing the course, I still do not understand the mining process, the link between blocks and transactions, where the mining reward comes from, the governance of the community... It is both false and not politically neutral to say that governments "manipulate" the value of currencies. The control over the value of currencies is mainly performed by central banks which are independant of governments.
By Rob Williams on 4/1/2026
The instructor was very clear with his speech delivering easily absorbing information at a steady pace. Despite thus information being dated, it is still very useful to get the core background of both subjects. A+ to George Levy.
By Mark Stanley on 3/4/2026
Very informative course - would recommend to anyone looking for a course which provides the concepts of blockchain and Bitcoin in a straight-forward and understandable way.
By Pamela Corona on 2/26/2026
Es la primera vez que obtengo una explicación clara, sencilla y completa de cómo funcionan los bitcoins y el blockchain. El instructor es excelente.
By Renee Kagan on 11/22/2020
Yes I am enjoying it, but I have no technology background so it is still a bit over my head.
By Victor Ondicho on 11/22/2020
it has been a wonderful experience as the lessons are easy to understand for me as a beginner
