Careful design, novel form, professional knowledge, unique insights, lively style, Professor Shuo Bai’s blockchain course is the best textbook for everyone who wants to learn blockchain or understand blockchain knowledge. I sincerely recommend!

Blockchain is the cornerstone of the Internet of value and an inevitable trend in the future development of science and technology. Professor Shuo Bai is a pioneer in China's blockchain technology. This course thoroughly talks about the basic knowledge and the application of blockchain. It is the best choice to understand the blockchain technology and its application.

Blockchain courses on the market mostly boast how new technologies change the world, lacking rational criticism. This course is completely different. It analyzes the meaning of the blockchain from the aspects of technology, products, industry, etc. It talks about its value as well as drawbacks. This neutral and calm attitude is especially valuable in the current impetuous environment. Professor Bai’s lecture is highly expansive: it compares across multiple fields and comprehensively analyzes specific problems. I think this is probably the master’s style.

This is a course that truly facilitates understanding. It treats blockchain rationally and never boasts. It is a stabilizer in the bear market. The lecturing model combining knowledge points, cases and opinions makes learning blockchain knowledge easy, and after-school thinking is very challenging. Such a systematic course is more valuable to beginners and practitioners than fragmented knowledge.

Professor Shuo Bai, as a giant in the field of computer science, talks about blockchain so thoroughly that a beginner like me could understand it. Every chapter comes with new insights and leads to more thinking. Compared to other general blockchain courses, this course is more in-depth and structured, and pays more attention to the technical and logical aspects.

Blockchain is a multi-disciplinary emerging industry, so it may be prohibitively inaccessible for the crowd. Professor Bai’s years of professional experience laid him a solid knowledge foundation. He clearly explains blockchain in a simple way. The course content is rich, the system is clear, and the words are concise. After a long period of polishing, it is the best choice for beginners. I strongly recommend!

Fortunately, I participated in the alpha test of Professor Shuo Bai’s “From Introduction to Application: Blockchain Revisited”. The course progressively introduces the development of blockchain. If you want to easily gain a systematic and comprehensive understanding of blockchain, this is the course for you. Believe me, you will not be disappointed. However, if you have relevant knowledge already, then this course is not suitable for you, and you should find a more in-depth one.
