Bitcoin Forum

Hello All,

   I see a lot of depression here when you join up at the forum and are restricted to the newbies section. Well anyone that knows me from the IRC channel #bitcoin-otc, where a bot by the name of Gribble (great bot) resides, knows that I every-once in awhile put out a BTC_Challenge. Some are easy, some are hard, and some go unsolved because of a time limit.

   Well don't tell anyone... shh... keep it a secret... in this section where all the l33t5 won't come. I will, every-once in awhile, offer the same to you. This is a simple process for FREE BTC. I will pose a problem, either with a time-limit or without one, and the first to post the correct answer will win.

 This is the important part: Post your receiving BTC Address with your answers... If you forget, I will pay the first correct answer that has the BTC Receiving address.

OK. For the first BTC_Bear BTC_Challenge.

Many might know that you can see transactions to an address by using blockexplorer.com Well lets do a pretend look up.

You look at : 1QCyFFRxZuzHAPKNQw5gWBzLWnHXNHxi86 and (not for real tho) and find these transactions sent to the address in different blocks at different time intervals.

1.71 BTC, 1.82 BTC, 1.73 BTC, 1.66 BTC, 1.66 BTC, 1.76 BTC, and 1.69 BTC as the transactions to that address. (if it wore possible to do so)

Here is your Question for 1 BTC to the Winner. You will in no doubt know you figured it out when you do,

What do the above transactions represent? First to answer correctly, Wins.


Remember don't tell anyone I'm here  ;D

I will check back later to see who has won, if anybody.

BTC_Bear

Seems like payments from a mining pool to me.

Incorrect

it's a communication channel, and you just gave an idea to terrorists how to communicate circumventing echelon (maybe).
btw. this post could also be one of those messages (joking).

.xx is the ASCII CODE

So if I'm right the message would be 'GRIBBLE'.

You are correct and Win

ps, please post that you have received the btc

Now, after a few confirmations... you will be able to see that I sent the 1 btc to the address given.

http://blockexplorer.com/address/1CniheL4RHAsUK8E2LzziR7N4QgkZHYeM2 (http://blockexplorer.com/address/1CniheL4RHAsUK8E2LzziR7N4QgkZHYeM2)

or he confirms it.


And for any existing and would be terrorist... something tells me the NSA and/or CIA have a copy of the BlockChain.  ;D

Yes I did receive it.
Thank you and I'm waiting for the next challenge if I'm allowed to participate in more then one

You are as anybody is...

Just keep an eye out for them here...

ROFL I can imagine the CIA analysts trying to find this kind of patterns in the blockchain

First to post :  >BTC_Bear apologizes to BTCHero< in #bitcoin-otc Wins... the btc... but the next challenge will be harder... :))

challenge WON... Prize Sent

Hopefully the apology goes a long way to making amends.

Transaction received, thanks !

what makes you think this?

For 0.31415927 BTC:

Below are the answers to a question taken directly from a GMAT test:

a)   4π sq. inches
b)   8π sq. inches
c)   16 sq. inches
d)   16π sq. inches
e)   32π sq. inches

What was the original question, which answer is the correct answer, and why?

Yes, it is possible.

d) is the correct answer
0.314... was a good start(pi) and then  I decided that d) is most similar to other 2 answers

...and then I found this: http://jnlnet.wordpress.com/tag/social-science/

guess I was right with much less logic

1CniheL4RHAsUK8E2LzziR7N4QgkZHYeM2

Thank you.

You make is sound like you basically guessed at the answer and then used Google to check your guess.

This has been a valuable learning experience for me and makes me really feel for any teacher nowdays that is trying to get their students to think and discover things for themselves.  When the answers to every question are so easily available people don't get to have that feeling of discovery that comes from actually thinking through a puzzle and finding the answer themselves.

You did get the correct answer and although it is not at all what I was looking for the link to the answer does satisfy the other two parts of the question, namely what was the original test question and how can you know the test question by just looking at the answers.

BTC grudginly sent.

Then pose a better question:

()® 1 t4at 15n't s0 3saLy g00g1ed...

OMG That says "Or 1 that isn't so esaLy googled..."

what do i win? :DD

The smartest student, I think, is the one who finds the most efficient means of passing any examination or test they come across.

Yes, even by cheating. 

For 0.1271828183 BTC, What is stored in alpha when this pseudocode is finished executing? (EX: Alpha contains {0,1,2,3,4})

int[] alpha = new int[5];
int j = 0;

While(j<5)
{
   alpha[j] = j + 5;

   if (j % 2 == 1)
   alpha[j - 1] = alpha[j] + 2;
   j = j + 1;
}

{ 8, 6, 10, 8, 9 }

1PZC1SaB3r3JJgLz3xnvNt6cQbZ9ggtAxF

Good game but, what's in it you?

That's correct.

I wanted an excuse to give e away. :p

Wouldn't that be 0.27182818 (e/10) instead of 0.12718281 then?

Yes. :) But it was too easy, so I didn't want to give 0.27182818 away. But 0.02718281 is too little. So I added a 1.

OP, if you offer more of these challenges and I happen to catch you on phrasing the challenge question poorly, or some other error that places the question out of the context for which it was intended because I can't POSSIBLY be bothered to look up the how to calculate your answer and subsequently perform said calculation, but yet, simultaneously, happen to have the time to construct this long-winded plea in hopes of gaining an edge in this competition-for-brainiacs, would you graciously accept my sound linguistic reasoning as a suitable replacement for an answer and reward me with digital delight (i.e. BTC)?

bwagner's question was immediately apparent to me.  Perhaps having memorized pi to 8 digits in college helped me.

The first to post the Alphabet from a...z, backwards from z...a and upside down. WINS 0.5 BTC

Should the whole thing be flipped upside down ( ɐqɔpǝɟƃɥıɾʞlɯuodbɹsʇnʌʍxʎz ) or each individual character ( zʎxʍʌnʇsɹbdouɯlʞɾıɥƃɟǝpɔqɐ ) ?

WINNER, but are you forgetting something?
