The exam will consist of 50 multiple-choice questions. Each question has 4 possible answers.

The questions will be presented in 10 pages (5 questions per page). Once you finish with your responses for each page, you can proceed to the next page. 

There are two types of questions: 

  • Radio buttons (where only one answer can be selected as correct) 
  • Checkboxes (where more than one answer may be correct). In checkboxes, AT LEAST ONE answer is always correct.

The exam is open book: you can consult course materials, research the internet and any other external sources you think appropriate.

IMPORTANT: You must submit your responses and sign them with your wallet before sending them for validation. This is a critical step to ensure that your responses are properly recorded and graded.

Centralized (non-NFT) versions are available on the course website. Go to, click on “Course Material”, and download all PDFs in a .zip file.

Alternatively, you can find and download each presentation next to each video of the main sessions at
