I recently built a simple web app to test the knowledge of general blockchain facts and history: allocker.com. The design is minimal, and much of the build was assisted by AI, but the questions themselves were crafted by a real human. You can take a short quiz, receive a certificate of completion, and verify any past certificates at allocker.com/verify. You will also get a list of source web pages for every incorrect answer, which will help you learn a lot more! It was a small but fun project.
