I'd be interested in seeing this exam!


You won't, because then it'll turn out to be nonsense.

This is always how cryptocoin nuts argue.


What is the maximum throughput (tx/s) that some systems can achieve?

Do you really need to go through all the history of the system in order to be convinced of the latest state?

What are the different ways to decide who should be the next person that gets to choose the next block of transactions?

Can you hide the amount you’re sending? What about the recipient? Or your own identity?

Can you transfer bitcoin into ethereum or more generally one cryptocurrency into another?

Is it possible to send funds to a recognizable shortname instead of an hexadecimal string?

Are there ways to protect your funds with several keys instead of a single one?


- 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?
