Certified Blockchain Expert (CBE) is an online certification program bundled with a self-paced online training of 5-6 hours followed by a one-hour long exam of 45 multiple choice questions.

You have to clear the exam with 60+% to get the certification via email in your inbox. You get 3 attempts to clear the exam but if you fail even after 3 attempts you have to reach out to support team to give you additional attempt along with the support to understand where you are lacking. There is no specific duration as the video tutorial is self-paced, but if you want to complete it in one go then the duration is around 3-4 hours. 

The cost of the certification and training is $99.
