- Literally a google search for that + bitcoin gave me the answer

- No

- Another google search for "bitcoin + <your question>"

- "Yes" for literally the rest of the questions.

This wasn't an exam, this was basically an advertisement for "look what cool things you can do with this"

If I got any wrong, whatever. I have literally never researched bitcoin or blockchain. If I got them right, well... nice try on the exam I guess.

Answer to question two is yes for Bitcoin and all blockchain like that. There are some new ones like Mina who propose a different system in which you only need to verify the last hash.

Answer to question three is not restricted to Bitcoin. There are many other systems, e.g. Proof of stake (POS).

You got them all wrong. I wasn’t talking about bitcoin specifically but about cryptocurrencies in general. If you’re interested in learning I can help but not with that attitude.

This means that YOU failed to write a good test because the questions were not specific enough.

Where did I write the word bitcoin?
