Lesson 1: Polyhedra and zero-knowledge proofs

3 questions

  1. What is Polyhedra's mission?

    Correct answerBuilding the future of intelligence

    Note: An older answer, "building a seamless and secure bridge between Web2 and Web3", also circulates – probably from an earlier version of the course. Pick the option about intelligence if you see it.

  2. What is a zero-knowledge proof?

    Correct answerA method to prove truth without revealing details

    Why this is correct

    A zero-knowledge proof lets one party prove a statement is true without revealing the underlying data.

  3. What is the name of Polyhedra's proof system?

    Correct answerExpander

Lesson 2: zkML

3 questions

  1. What challenge does Polyhedra address?

    Correct answerAll of the above

  2. What does zkML stand for?

    Correct answerZero-knowledge machine learning

    Why this is correct

    zkML combines zero-knowledge proofs with machine learning, so an AI result can be verified without exposing the model or the input.

  3. Which is a real-world application of zkML?

    Correct answerAll of the above

Question wording may differ slightly from your app. Look for the answer text rather than the option's position.

Where to find the Polyhedra course

Crypto → Discover → Learn → See all in the Revolut app. The course is listed under Polyhedra Network.

What the course is about

Polyhedra builds zero-knowledge proof infrastructure. Lesson 1 explains what a zero-knowledge proof is and names Polyhedra’s proof system, Expander. Lesson 2 moves to zkML – using proofs to verify AI and machine-learning results – and its real-world uses.

About answer positions

Answer keys that give only option numbers (for example “2-2-3”) are unreliable: the option order does not appear to be fixed. Use the answer text above instead.

If the reward did not arrive

Check that a reward amount was shown on the lesson before you started. If it was, wait up to two business days before contacting Revolut support.
