We are B9lab

B9lab is the world’s leading provider of blockchain education, training and talent. Through our online academy and on-site training workshops, B9lab works with clients ranging from leading global institutions to talented independent developers all over the world.

Founded in 2014, the company aims to demystify the field by helping decision-makers prepare for technological disruption and certifying developers to drive that change. B9lab also offers advisory and talent services to help organisations find the best technological and professional fit for their blockchain projects.

Our Story

Bitcoin piqued the interest of the B9lab founders in around 2009. When it became apparent that smart contract platforms were actually feasible (around late 2014), another thing became immediately clear: the blockchain community needed high quality, consolidated training materials so that aspiring blockchain developers could upskill in weeks instead of months or years. Hence, B9lab: an online academy where developers and non-programmers alike can receive best-in-class education, training and talent in blockchain and decentralised applications.

B9lab was one of the first to come out with a quality online training course for aspiring Ethereum developers back in 2016. Today, our global learning community has grown to more than 13,000 students in 125 countries and our certification programme is among the most reputable in the blockchain space.

Whether you are a team or individual learner, B9lab exists to enrich and accelerate your blockchain learning journey. We also want to help create a more diverse community from a wider variety of backgrounds, both technical and non-technical. So, whether you read an article, watch videos (or sign up to a course) we encourage you to always be learning.

Why choose B9lab?


Protocol neutral means we do not favour a single technology stack over all others as many other providers do. B9lab aims to offer the widest possible range of different blockchain technologies to provide a balanced, well-rounded educational experience.


As one of the first organisations to offer education and training in the blockchain space, our clients can count on years of teaching experience and in-depth courseware that is hard to find anywhere else.


Our expert instructors provide “active tutoring” - that means one-on-one personalised support. From answering questions on Slack to individual code review, this rare and highly valuable service level is impossible to find on a free MOOC.

Up to date

With monthly cohorts and weekly content releases, our top priority is to make sure our courseware is never outdated and always at the leading edge of the industry.


We put our clients first to meet their learning and training needs in a flexible, empathetic and understanding way.


We pride ourselves in making sure alumni get a sense of the social and ethical implications of blockchain development. That’s why we co-developed the Satoshi Oath: the first-ever code of ethics in the blockchain space.
