“Choosing B9lab's Certified Online Ethereum Developer course was a no brainer; there is no equal competition to it, when I read the course curriculum, the mini challenges and projects, the certification process (and the high mark to get it); I was sold!”

Adel R.

“B9Lab's Ethereum Developer course provided me with a solid, pragmatic foundation not only to building distributed applications but also to staying attune to the evolving Ethereum ecosystem. B9Lab's approach of learning the fundamentals of blockchain, cryptography and the EVM combined with valuable instructor feedback on smart contract code allow you to navigate learning in this open source environment with a strong comprehension of the nuances of Ethereum's design.”

Karen S.

“I started my blockchain education with a MSc. in Digital Currencies from the University of Nicosia. It was ok, but I realized I missed coding. This is how I came to B9lab. All seemed to come together in this course: my economics background, blockchain interest, love for coding… so I took the leap and haven't regretted it for a moment so far!”

Rinke H.

“The projects where you actually build something yourself was huge and most courses don't have that. Other courses passively walk you through a project step by step, but without hands-on practice it's just not effective learning. It's not a real-world job situation. B9lab creates a more realistic expectation.”

“With simple explanations, practical exercises and instructor support, I was able to understand and master all the needed blockchain skills. Now I’ve passed all the technical interviews and am negotiating better offers.”

Mohamed Y.

“Thanks to the B9lab team for arranging such a good material for the Ethereum Developer Course, they were able to keep the pace on this constantly evolving technology. Instructor support throughout the course and overall expertise on the subject was outstanding.”

Alberto P.

“The instructors were fantastic with their support, in particular their code reviews and discussions. Rather than spoon-feeding the answers to questions they would usually give hints to help me find the answer myself, which I believe to be far more valuable. I wouldn’t hesitate to recommend this course to anyone who wants to get a solid handle on the entire Ethereum ecosystem and dApp dev workflow.”

Nick F.

“Programmable money is serious business, so when I decided to get into smart contract development I made it a point to learn from the best. I'm thrilled to receive my official certification in Ethereum development from the fine folks at B9lab.”

Adam S.
