ARG Puzzle with 3.5 BTC Private Key Prize, Game Over

[Prospero]

*Hint for "Onion.7z":

- Match the identified platonic shapes to their designated elements in the correct order. Always apply Bitcoin protocol.

Seem we might not be finished over here either...

means 2.7z is independent of Again.7z ?!

Onion.7z was the first 7z and that was already opened. OP must have made a mistake this time I think she meant 2.7z.

bahhh.. i had the order of the elements wrong.
Its sha[sha[fireearthairetherwater]]
a175b1d5f92f57acc6920f3e73869e0b154b8dd97249c84224eefbdd6bde2f77

hash confirmed as key for 2.7z.
Contains two files:
3.7z and Algo.jpg

[Timmmaahh]

well it must be something like

fireearthairwateruniverse

then double sha

or

fire earth air water universe
or

fire earth air water ether

its bruteforcing

the space.mp4 could mean that there are spaced beetween the words..

*Hint for "Onion.7z":

- Match the identified platonic shapes to their designated elements in the correct order. Always apply Bitcoin protocol.

Just to point out, that's not bitcoin protocol at all. Bitcoin protocol uses the sha256 of the binary form of the inner sha256, that's the hex form. It's not Bitcoin protocol at all, just similar. OP misunderstands how the hash functions work in Bitcoin, it's a subtle difference if you're not deeply into crypto.

[Kprawn]

Can you post those files pls?

Thanks.

[Timmmaahh]

Edit: file named Algo.jpg

thinking about an algorithm ... thales' thereom? (no algo )

[jc01480]

You guys are doing awesome!  Two thumbs up!

[Kprawn]

And the 3.7z ?

[Mitchell]

And the 3.7z ?

We are working on that one right now.

Triangular numbers: https://en.wikipedia.org/wiki/Triangular_number#Triangular_roots_and_tests_for_triangular_numbers
And 2147129 from Number.txt passes the test.

Argh, yeah. I had done this and many variants (e.g., "Fire Earth Air Ether Water") a couple hours ago, but didn't post due to our progress elsewhere and the failure of the key to work.

Code:

echo -n "fireearthairetherwater" |openssl dgst -sha256 -binary |openssl dgst -sha256

its not passing?

Yep. Took me ages to work out what the hell was going on with that.

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

EDIT: also, more info from OP

Edit2: First post changed again

*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?

[Coinkle]

I take a 9 hour break to sleep amd try to recover from this damn sickness that I caught. & I had to read 13 pages. Holy Crap. You guys are busy, busy.
A lot has been solved and I need some time to catch up.
 
That ARG guy might finally realize how annying he was being after his last comment, which may actually provide to be useful, if anyone decides to stop ignoring him

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

I don't like this new hint, at all. I would choose for the "Again" file since it was hidden in the Exif (and hidden things are what we are looking for). That being said, he/she/it could use reverse psychology to direct us to the wrong file. I am so confused.

me either, we're working on this so hard and in the end 1 will get the price and 50 will get out with nothing .. thats the sad part

Well, if I somehow manage to get the private key, I will share the wealth with everyone that really helped.
