Quiz

Twelve questions, one correct answer each. The quiz marks every answer as soon as you check it, explains the reasoning, and at the end gathers anything you missed into a short review with links to the matching glossary entries.

Take the quiz

How the marking works

Each question has exactly one correct choice. When you press Check answer, the quiz shows which choice was right, says whether yours matched, and gives a short explanation. Correct and incorrect choices are flagged with words and symbols (“Correct” with a tick, “Your answer” with a cross), never with colour alone.

The score is the number of questions answered correctly out of twelve. The result page lists every question you missed, shows your choice beside the right one, and links to the glossary entry that explains the idea. If you answer everything correctly, the full set of explanations is still available to read through.

Assumptions and edge cases

What the questions cover. Every question is about vocabulary and design facts that do not change: the supply cap, the block interval, the halving cycle, the hash function, the unspent-output model, and the common meanings of everyday terms. None asks about prices or events.

If you press Check without choosing. The quiz asks you to select an answer first and does not count anything. You will not lose your place.

If you change your mind. You may change your selection freely until you press Check answer. After that the answer is locked, so the score reflects your first checked choice.

If you stop part-way. Using Stop and start over discards the current run. Only a completed run can set a new best score. Browsers that block local storage still run the quiz; the best score is simply forgotten when the page is closed.
