I'm bored, so I decided to create a puzzle. At the end, you should end up with the private key to this address: 12gDdRbHyQ36mRS8ZhPVsjaHvkKGoTJhRS (https://www.blocktrail.com/BTC/address/12gDdRbHyQ36mRS8ZhPVsjaHvkKGoTJhRS), which has 1 mBTC in it. I'll be giving hints edited into this post probably every so often (probably daily). Please post here if you manage to solve the puzzle.

Good luck!

it can only be accesed via your IP adress

No clue what your talking about. The puzzle has nothing to do with blocktrail, and if you do it successfully, you get the private key to that address. I simply linked the address on blocktrail. The puzzle is the image I posted.

I did a bit of thinking, and decided to add a second clue.

Following. The clue is just not enough ... I will try to 'break' it. :).

We want more clue still trying to solve it now , i would like to solve this puzzle also i want to learn something  ;D.
Ok , let's take a look about update in this thread.

It looks like someone has figured out the clues.... What is the third clue?

5 potato

Another kind of puzzle which I don't really understand.
Can someone please explain how this is solved? I am really intrigued since the first puzzle I encountered last time.

Well its a gif image in the first clue.
Stare at it long enough and you will see a 5 potato sign.
Find any hash online calculator and you will get this: 336eff8e277d5442b3ebd725c86952c68fa6d2a6d79275e8bb8afe41561d3725
Not sure where was the challenge in this one. Figured it out on the spot.

Take the hash as the passphrase for a BrainWallet, and you get the private key. Looks like some people were close, but didn't get the brainwallet part. Congrats to whoever did though. It would have been harder without the hints, but I thought it was too hard.

Here is the solution:

1. Take the image I posted and use gifsplitter to see all the frames. You will see a frame with "5Potato".
2. Get a sha256 calculator and convert "5Potato" into a hash. You get 2b9ac4168bfc892c43de6904680899b5cbcdfef0ad12bacd6e78ab1d7895ec3f
3. Use bitaddress.org or another brain wallet website and use 2b9ac4168bfc892c43de6904680899b5cbcdfef0ad12bacd6e78ab1d7895ec3f as the passphrase to a brainwallet, which has the private key of the address with 0.001BTC.

Congrats to poptok1 who managed to figure it out. I think it was too difficult for me- I don't even know what is a SHA256 calculation!

Thank you 788bitcoin but it wasn't me that took the prize.
It was free to participate for everybody and even someone without forum account
could grab the prize. Best way as you see is to learn through fun. Now you know :) what
those encryption algorithms are.   

why fast people and know how to decode it always wins that would be great if you do it i
know you do giveaway but not decoding

your giveaways are hard tho
