Here is an updated list of the wrong answers:
http://pastebin.com/ntDatjH7So what I am thinking about now is this:
The clue was "{you want the solution before you ask 4 the key and bin it}". So I think we should do something with the base-4 binary system.
The problem here is that a letter doesn't fit in.
Another problem is the calculation. Which calculation should we use? I am currently thinking about 100+001+000 = 101 or in binary 4+1+0=5 or in base-4 binary: 16+1+0=17. Also it isn't clear here how to use a letter.
Edit: steveturk, it is not that I don't trust you, but can you do this for me:
Put the answer with a random string of letters and numbers in sha-256, so we can check if this ended if you didn't change the outcome to let someone win.
I am already in a position to do that, changing the answer is impossible due to the clues already given, I thought of this, so have made provision in case someone can't get the answer and starts with the scam acusuations (for example, the 3 virtual coins was uploaded to tinypic in sequence in advance, in case someone thought I would change out the coins).
{glad to see the you have managed to get alan turing, charles babbage and alonzo church working together on this}
