ARG Puzzle with 3.5 BTC Private Key Prize, Game Over

[jc01480]

Guys, we're not in Kansas anymore!

[Prospero]

*Hint for "Onion.7z":

- Match the implied platonic solids to their designated elements in the correct order.

- Always apply Bitcoin protocol - "Bitcoin hash is the hash of the hash, so two SHA256 rounds are needed"

- File "onion" or file "again," choose a path. Is one in the future, is one in the past?

- File "onion" or file "again," choose a path. Which one leads to bitcoin?

Is there a different Onion.7z? I take this to meat either solve Again.7z (Numbert.txt + Space.mp4) or 3.7z + Algo.jpg

[Timmmaahh]

do we have to calculate something for the password of 3.7z? what do you think?

[micaman]

Apparently there's nothing relevant in Algo.jpg's EXIF.

[Gatekeeper]

Strange to say which path to take, because there isn't a password to get on the Again.7z, unless we're going off in different direction again, the files within it both open so there's no clear path to take. The other path carries on needing passwords. So if we go Again path then we don't actually know where to go next

im so confused xDD

OP you're doing awesome work !

According to Wolfram Alpha, it's not a triangular number.  

http://www.wolframalpha.com/input/?i=is+2147129+a+triangular+number%3F

"if the positive triangular root n of x is an integer, then x is the nth triangular number"

$ bc
((8 * 2147129 + 1) -1 )/2
8588516.00000000000000000000

I have to challenge your result here Prospero, sorry about that. Dug out my old mathbooks from the university to verify, it might still be wrong though so if someone else could verify it Please do.

Yemmster: Your answer is not an integer. So does that mean its a dead end

my bad. i forgot to add the sqrt() call while i was busy checking the parenthesis were where they should be

[Prospero]

Yemmster: Your answer is not an integer. So does that mean its a dead end

OP has confirmed the two different files are unrelated, so this was a dead end anyhow.

[Coinkle]

Do we collectively think we should work on both?

Do we collectively think we should work on both?

I think that is the best course of action, but it will take us more time to solve the puzzle.

[Timmmaahh]

I got an answer but my work computer wont let me access next step.

So I will have to update tonight from home computer.

we might help you

triangle with 10 dots inside it looks like Pythagorean Tetractys

You could tell us. I'm pretty sure we are far from the end anyway

triangle with 10 dots inside it looks like Pythagorean Tetractys

It sure does. Also tetraktys represents the four elements. And a circle represents the fifth element.

bahh. sha[sha[again/Again/again.7z/Again.7z]] doesn't work

- **New Hint: Continuing on from "Elements," keep thinking "Greek geek speak."

Another hint! OP is being generous (or has mercy) with us.

[Yemmster]

With the new hint I'd have to agree with the theory of Pythagorean Tetractys, rather than Pascals Triangle which was what I was about to write.

[Coinkle]

If this goes on for a month I'll be batty for sure

With this hint my answer was not even close.

Ah man, that sucks to hear. What did you have in mind then? It might help, it might be useless. You never know.
