[CLOSED] ►►► 2016 Bitcoin halving tribute puzzle ◄◄◄ **SOLVED**

[miffman]

Hell this is hard. Took me like 3 hours already since yesterday.  
Cant stop thinking about this its not about the reward any more.
Anyway I came up with this: Cartesian three-dimensional coordinate system.
But its not matching hash...  

Why three dimensional?

Anyway I came up with this: Euclidean three-dimensional coordinate system.
But its not matching hash... 

Thank you for the feedback poptok1

As mentioned in OP the contest will be over at halving day, we are only 1450 blocks away.
The last hint will more or less give the solution directly, so I really hope someone solves it before

The last hint that was just provided points to a Cartesian coordinate system, but 2 dimensional due to a prior hint pointing to pairs of X and Y coordinates.  It's probably a sum? The only monkey wrench is numbers are only up to 25.

YIKES! Is the phrase letters only? Any punctuation or space?

5. Hint:
"Cogito ergo sum" - A particular idea from the gentleman below can help you solve the puzzle.

 Descartes : "i think so i am.."

XY : 24 - 25

but rubiks cube have :  01 . 01 on a face ( what suggest binary .. )

pweww... that's will drive me crazy..

[miffman]

I was thinking, maybe it has to do with the cartesian product? It makes pairs from sets and the way the pairs are arranged in any set doesn't matter.

6. Hint:
"The pen is mightier than the sword" - Pen and paper can be a powerfull tool.

Wow I've been watching this... Well done to Took for the idea and to the winner!

[pawnshop770]

Yep its was a QR code once it was plotted

Sorry CITM, looks like pawnshop770 beat you with 4 minutes.
I would like to give you a 2nd place prize, even though it was not defined in the rules, I will send you a PM.

WTF 4 minutes? He just reposted
Besides it was impossible to solve this with pen and paper.
If plane was big (A5) and dots where small (ball pen) no way anything
could read that QR. I know because I tried.

[coin@coin]

Any more info on how it was plotted?
Or url where to learn more about these things?

There is also an unsolved puzzle from Coinartist here: New Bitcoin Puzzle.

You are correct, the dots in hint 6 would not be large enough to actually scan the solution.
However, the idea is that once you start plotting the points, then would you quickly realized that it was a QR, and then would you shift to another medium.
If you made squares on the paper instead, then would it scan, but that would have been slightly easier if I have used squares instead.

This was a really cool puzzle! Thanks for making it Took!  Maybe I'll get the next one
