Hallo allerseits ich bin grad dabei folgende Wörter words = [     "black", "this", "order", "find", "real",  "subject", "food", "truth", "hidden", "future",  "freedom", "power", "moon", "tower", "welcome" ] vollständig miteinander also 455 Kombination mit jeweils  479.001.600 Permutationen durchzusuchen ich werde euch in ein paar Tagen Rückmeldung geben was die Suche gebracht   Hat . 

Hello everyone, I am currently in the process of exhaustively searching through the following words:

words = [ "black", "this", "order", "find", "real", "subject", "food", "truth", "hidden", "future", "freedom", "power", "moon", "tower", "welcome" ]

That means checking all 455 combinations with 479,001,600 permutations each. I will get back to you in a few days with the results of the search.

[S0LAR11S]

I really hope someone can solve this puzzle.
 I've been trying, but I give up.
My dream was to buy a motorcycle with it  especially the GIXXER SF 250. 

[demesmaeker]

I tried the following seed words (in ALL combinations)

subject camera tower mask police liberty eye black pyramid vote moon rifle

black subject face mask police order find liberty proof time world vote

moon tower food real black subject time proof only win world face

air mask police black matter vote order first liberty hidden peace future

subject camera tower mask real six liberty eight eye black pyramid police

subject camera order this real black matter peace tower moon food gun

subject camera order mask police this liberty real eye black pyramid vote

moon tower food real black subject time proof only win world face

So, no one else has to waste time on those

[S0LAR11S]

Hi guys, like many of you, I tried to solve the puzzle hoping the reward could change many aspects of my life, But you know... I'm giving up, because life and reality are consuming me.
The first thing I would’ve done with that money would’ve been to help my mom and buy myself a motorcycle so I could fully focus on my studies.

 Here I leave the little progress I made or the few keywords I came up with (so you could have more hints).

(moon tower food breathe black this subject real bitcoin day tuesday ten twenty liberty peace hope faith voice future change truth light guide answer order proof act)
(day tuesday ten twenty moon tower food breathe subject this real bitcoin liberty peace hope faith voice future change truth light guide answer force order proof path)
(black this subject real bitcoin moon tower food breathe day tuesday ten twenty liberty hope faith peace voice future change truth light guide answer adapt act proof order)
(liberty peace hope faith moon tower food breathe black this subject real bitcoin day tuesday ten twenty voice future change truth light guide answer force act adapt proof)



I hope someone can solve the puzzle at some point, greetings to u all.

@accanbtxx86

i know somewhat C++ if you can atleast analyze the code i dont want to be alleged of backdoors   
i can provide you with the code that will run on multiple core specially Xeon processors.
why am i not using it myself? i dont have the resources to allocate to this.  the seed may or may not be correct or maybe a 24 word list but if you wanna try let me know Happy to help .

i donot want any split or share ...

[beridzee]

Hello,

I'm sure it's a little easier here - regarding the hidden and encrypted words! I'm sure everything is written right here, right in front of us. We need to start correctly; the main thing here is to find the key that will give instructions on where to begin and where to end. We're looking for a seed phrase, and there must be hidden instructions on where to begin. I Find some Hidden new under structure paintings while playing with Contrast/Colors/Saturation.

Where to Start and How to Move, Your Opinion?!

[cnashe]

The timeline of events is the order of the seed phrase.

The image is telling the following story:
"Today, black people stand for justice, peace, love, freedom, health, and safe change; guard our future, vote blue, join the city march, work, and wear a mask."

]If anyone is still actively working on this, let’s chat as I think I’ve found some stuff that I haven’t seen reported anywhere else yet.

- The Presidents are wearing opposite color ties, which hasn't been commented anywhere. Trump should be wearing a red tie and Biden a blue one, but they’re reverse.

- When you use color blending, specific items in the picture "light up" as clues. https://imgur.com/a/Z8oksqm

- If you remove central text in the image using AI, there's unreported letters and numbers now faintly visible. I believe they’re 157XIN.

- If using zsteg, there’s some jumbled code within the file itself that give a false positive for a PGP message but there’s nothing actually there.

[Developement59]

I solved it however I left the coins in the wallet. I dont need the money im working on something else i developed. However all I have to say is good luck


I developed a site that solves btc puzzles automatically  It has all the tools you need  its very unique and powerful with so many tools and I but I was able to solve this puzzle without it. But I left the coins in the wallet for the next person to solve it. The only thing I can say is it takes more than just trying to brute force it. The words to use will confirm themselves if you look for the right pattern amd follow the hints. If anyone interested in my btc solving site let me know but its not cheap and if you think your going to use it to solve this puzzle im here to let you know its not going to help unless you find the secret of the puzzle however it will help you along the way if used correctly  with the right logic

Just a child's fantasy

[ArmaCorex]

I rented a bunch of GPUs and tested every possible mnemonic combination, assuming it is BIP39 12-word phrase with/without a passphrase, and using the words suggested by the hint. In total, 377.2 billion mnemonics were scanned.
At this point, I'm not sure whether this puzzle is legitimate or just a waste of time and money. There may be additional words somewhere in the image, but the quality is too poor to tell for certain. If anyone has a higher-resolution version, could you please share it?

[S0LAR11S]

Hi, it's me again. After a deep search, I found some clues and inconsistencies regarding this matter. This puzzle is real but unsolvable as it stands, due to the fact that it has a passphrase. I got 2 confirmed positions from someone, which I'm very grateful for, but I don't have the time or the software to try them. I don't know what else to do, just good luck to everyone who is still working on this!

[desalzes]

Been working this one (stsh_n's 0.2 BTC "Brave New World", 1KfZ…HjkHZ) on and off for a while and have read through the thread. I've landed where a lot of you have: it's gated on a few specific words/positions, not on compute — ArmaCorex's 377 B run is about as conclusive as it gets that the answer isn't in the obvious word pool.

I've done a decent amount of work that I'd rather not share yet. If anyone here is genuinely close (a partial skeleton, confirmed positions, or the passphrase), I'd like to compare privately and work something out.
