Test Yourself: Are You the Ultimate Bitcoin Expert?

https://99bitcoins.com/test-yourself-are-you-the-ultimate-bitcoin-expert/



a little bit too easy (at least the first 25  )  but give it a try  

[Lauda]

Too easy? I doubt that. This test contains various questions, and some that Bitcoin users do not need to know (e.g. Merkle tree). I've made a few smaller mistakes that I hate to admit.


I'm not satisfied with my score nor the test. It sometimes takes more time than it should for verifying the answer and going to the next question.

[NorrisK]

Was quite ok the test. Some questions were a bit hazy, which led to some mistakes, but I think I did quite well

You got 42 out of 51 right!
You're a Bitcoin guru!

You're one of the most bitcoin educated people out there. Amazing job on completing this quiz with such a high score. We'd love to get more ideas for questions from people who have such extensive knowledge about Bitcoin like yourself. If you have an idea just fill out the form below this quiz.

Someone explain me the link between "coin days destroyed" and the requirement for fees ?
This question made me mad.

Also a question state that you cannot change a transaction under any circumstances which I don't agree, what's double spending then ?
And what if there is only one full Bitcoin node running in the world and someone edit the database ?

EDIT : Got 45 btw

[DannyHamilton]

Got 46 out of 51 right.

However, I'm confident that at least 7 questions had only incorrect answers to choose from. I managed to guess which incorrect answer the quiz was expecting on 3 of those questions.

Additionally there was 1 question that I misunderstood due to it being phrased in a confusing way.

Yeah these are the 2 questions that got me as well. Miners can change a transaction under special circumstances is indicated as false. This is a mistake, made by whoever made this quiz.
Well the idea of 'coin days destroyed' was implemented to efficiently measure the economic activity in Bitcoin. Someone could manipulate the statistics sending his coins back and forth non stop, and for this very reason it was implemented. The purpose behind it is to give more weight to coins which haven't been used for some time. 10 Bitcoin which haven't been used for 20 days count as 200 spent yesterday.

However, I do not know how this is related to fees and I've made a mistake there as well.

I'm going to assume that you know the answer to this question. Please explain if you have time.

You've asked this question, which I've yet to see an answer for.

I understood about coin days destroyed.
Coin days destroyed are the number of bitcoins sent in the transaction multiplied by the days without moving them.
We know that :

Code:

priority = sum(input_value_in_base_units * input_age)/size_in_bytes

So the priority increase as coin days destroyed increase. It was simple as that.

That's why we see big amount of BTC sent and confirmed very fast without any fees.

I'm not satisfied with my score nor the test. It sometimes takes more time than it should for verifying the answer and going to the next question.

okay to be honest: i did the first 25 questions. Merkle tree is not that easy of course

[Amph]

40 of 51, i did not know about the date of the whitepaper and some other errors on question about transactions, double spend also tricked me damn....

[harrymmmm]

You got 49 out of 51 right!

You're a Bitcoin guru!

[iqbal14st]

49/51 and i swear the two i got wrong were badly worded

I Think that to answer the questions that needed extensive knowledge ..
not everyone can be completed more than 40 questions with the correct answer

[jeannemadrigal2]

I am not a bitcoin expert, I don't need a test for that!  I tried it, I got about half way through and then got bored.  I missed a few questions, where some of the answers looked almost the same.  But it was a fun quiz.

[Slark]

Its a good thing that you can see the correct answer after answering but I wish time the correct answer is highlighted was longer. Otherwise pretty neat Bitcoin quiz.
I gotta give it this test to friends to see how they manage.

[umatej]

You got 31 out of 51 right!

You're a Bitcoin expert!

[fryarminer]

Just do the test tomorrow if you are afraid of the results It will still be there tomorrow.

[jt byte]

Well i learned a lot
I missed the answer of the What is the Bitcoin whitepaper?
Can someone tell me the answer

[dothebeats]

Only got 38 out of 51 answers. The Merkle tree confused me quite a bit and other technical details about bitcoin. Seems like I'm not that knowledgeable enough on bitcoin to know those technical things.
