I'd be interested in seeing this exam!
This is always how cryptocoin nuts argue.
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?
- 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 three is not restricted to Bitcoin. There are many other systems, e.g. Proof of stake (POS).
