You just know what guys ?

I don't really know it would be solved ever.

The answer to this puzzles is 50/50% real or just created for ppl trolling...

Many of riddles was solved in a few hours/days after it was created and there was a more cash to win than here we just have.

IMHO the only one person which know the pass is the OP creator, no one else or OP creator just forgot this and his crying right know and can't believe of this all sh1t we have talking about Cheesy

GIVE SOME HINTS THO!!

f###ing right!

Hi Tsuyugushi, with that software for this puzzle need internet connection to find the key if put correct words? And will show a message when private key is found?

Hey friend,

I'm not sure as I am not the author of the software, Ligor is (you'll find his post on Pg 17 of this thread). IMHO, yes, it requires an internet connection, and will display a message if the private key is found. You might want to verify with Ligor how it works specifically.

Latest solution tried:

For some reason I felt like the answer was hidden in the question, so I did the following.

Step 1: Assign each word a number based on the length of its characters.

Why = 3
The = 3
Comb = 4
Of = 2
Natasha/Satoshi = 7
Otomoski/Nakamoto = 8
Has = 3
21 = 2
Teeth= 5
? = not a word
. = not a word
txt = ignore for this solution (assumed it was to throw us off maybe).

Step 2: Take this number list (3, 3, 4, 2 ,7 ,8, 3, 2, 5) and run it through some python code to get all the possible combinations that amount to 32 characters.

Code:
import itertools
numbers = [3, 3, 4, 2 ,7 ,8, 3, 2, 5]
result = [seq for i in range(len(numbers), 0, -1) for seq in itertools.combinations(numbers, i) if sum(seq) == 32]
print result

Step 3: Read results to find that only 1 combination consists of 8 different numbers (i.e. words).

Code:
(3, 3, 4, 2, 7, 8, 3, 2),      <-- this one is 8 numbers therefore 8 words, to satisfy the hint "8 camel case words".
(3, 3, 4, 2, 7, 8, 5),
(3, 3, 4, 7, 8, 2, 5),
(3, 4, 2, 7, 8, 3, 5),
(3, 4, 7, 8, 3, 2, 5),
(3, 4, 2, 7, 8, 3, 5),
(3, 4, 7, 8, 3, 2, 5).

Step 4: Run the words corresponding to those numbers through the permutation solver program provided by ligor on page 17 https://github.com/Igor-san/1BtcPuzzle, once with Natasha Otomoski for numbers 7, 8, and once with Satoshi Nakamoto. 40,320 possible combinations of the words corresponding to (3, 3, 4, 2, 7, 8, 3, 2) give 32 characters, the solver program goes through them in a couple of minutes.

Step 5: No results, no key found.

Step 6: Cry.

"Why 21 million? The truth is, it was an educated guess. The math worked out, or as close to it as I had wanted it to. Before settling  on 21 million however, I had considered making 100 BTC as the reward, and 42—the answer to life, the universe, and everything. But afraid that others would consider my reference to Hitchhikers Guide to the Galaxy a quip and at the expense of not being taken seriously, I changed it to 21 million," the author writes.

In This text he say why 21 Million
But watashi-kokoto have shit solution and only and Magic to disappear  Last Active: January 19, 2019, 03:50:45 PM

He say:
my approach
start with shit solution

SheIsCombingWithTheCombFeelsGood

then you can replace "The" with "A"
fill the extra space with new words

SheIsCombingWithACombThatMagical

then you can reorder

ACombThatMagicalSheIsCombingWith

or even

AMagicalCombThatSheIsCombingWith

put back "The", change "Magical" to "Magic"

TheMagicCombThatSheIsCombingWith



This makes it a guessing game and not a riddle/puzzle at all..in which case the answer could be literally anything OPs mind conjured at the time.

I was thinking.. 8 words 32 char....
an average of 4 letter per word....
it reminds me of the BIP39 wordlist... where all words have 4 significant letters (some only 3)

Maybe the question refers to that list somehow...?
there are 8 words in the question (not counting "?", "21", ".txt" )

I'm trying some COMB-inations.. so far nothing ...


The answer might not be part of the BIP39 wordlist at all. If OP just created a custom sentence in Brainwallet to fit the puzzle, it would invalidate bruteforcing with the BIP39 list.

blockladder / watashi-kokoto GitHub connection

Looking at blockladder's "project pr" forks, there is a user called bakujo. Not much by itself, but they are following one and only person: our watashikokoto.
blockladder and watashi are perhaps close friends.

https://bitcointalk.org/index.php?topic=2044123.0

Satohash seems like a commonly followed repository between them all on Github.

I mean, there are several possibilities here. It could be that OP expects us to input a 32 (i.e. 32 bytes = 256bit) char english worded answer, convert it to private key through some algorithm like the one in the link.

It could also be that OP is simply referring to an 8 word 32 char answer to be input into a brainwallet checker right away.

It could be that the answer to the question leads to a second clue that will contain the private key.

Who knows?

Be a poetist, please...

I mean: the title of the clue "WhyTheCombOfNatashaOtomoskiHas21Teeth?.txt" is a poem. C'mon! Use the rhymes...

You make it sound like you know the solution lol

So I'm tired of trying this weekend.

Quote
NATASHAOTOMOSKI --> SATOSHINAKAMOTO
is a permutation cipher. I've known this for a while. Here's the key:

Quote
e   b   c   h   m   f   o   a   d   n   g   k   j   i   l

Here's what I can't figure out. If the remainder of the phrase is also a permutation cipher, how do we extend this key? It does NOT work for the entire phrase.

If we can figure out the key for the WHOLE phrase, that'll give us the full translation for whatever the ?.txt file might be.

Someone skilled in decoding might have some ideas. Let's keep this going Smiley

edit:

Quote
E   B   C   H   M   F   O   A   D   N   G   K   J   I   L
5   2   3   8   13   6   15   1   4   14   7   11   10   9   12
S   A   T   O   S   H   I   N   A   K   A   M   O   T   O

Would you mind explaining real quick how you arrived at this key? (sorry, I'm just a simpleton)

https://en.wikipedia.org/wiki/Dental_notation

In following with my previous idea that the teeth reference is a literal one, I just discovered that Dentistry labels teeth from A-T, and 1-32.

Coincidentally, the phrase CombOfNatashaOtomoski does not contain letters outside of the range of A-T.

Might be useful..

I think Every Shot will be in the dark if we don't get how get privat key from our ideas! whe you will find something how you check it on correct ? 

Exactly!...how the heck do we check? For the love of everything, OP, release a second hint..
11  Economy / Games and rounds / Re: Ok, here's a 1BTC puzzle. on: June 30, 2019, 05:12:35 PM
Another Complete Shot In The Dark...

Idea 1:
What if we thought of the question as:

Why The (CombOfNatashaOtomoski) Has 21 teeth?

My reason to focus on CombOfNatashaOtomoski is that it's 21 chars.

Likewise, we can choose to interpret the question in 2 more ways:
Why The Combination "OfNatashaOtomoski" Has 21 Teeth?
Why The Combination Of "NatashaOtomoski" Has 21 Teeth?


Idea 2:

Letters like m, n, h can look like teeth. Depending on what you interpret to look as a tooth (e.g m looks like 2 teeth):

      1            2                3,4                                       5                      6,7                    8                                        9
W   h   y   T   h   e   C   o   m   b   O   f   N   a   t   a   s   h   a   O   t   o   m   o   s   k   i   H   a   s   2   1   T   e   e   t   h      

9 "teeth" in this sentence, or more or less depending on what you interpret as "teeth".    


Just trying to think super "out of the box"...
                    

Edit: Included more interpretations of the question

Hello all. I've been following this thread for a while, and I just made an account to share my thoughts with everyone. Most of my thoughts turned out to be exactly like Cassius' analysis, but I'll share them anyway. I am not a cryptography expert, coder, engineer, or anything of the sort, so I'm looking at this through fresh eyes and from a different mindset.

THIS WILL BE LONG.

Part 1: The Potential Watashi Kokoto / Blockladder Connection

1. From Watashi Kokoto's posts, and Blockladder's (OP) old posts (cached on google search), they both seem highly technically knowledgable. Blockladder in one of his old posts says he is "not an academic", but despite this, he and Watashi seem extremely knowledgable about advanced cryptographic concepts, algorithms, coding, etc. This to me is a +1 for the argument that they're the same person.

2. However, if Watashi truly is Blockladder, why was he the very first to reply in the thread with a hint nobody asked for? If I were OP, I'd wait a bit to see if people were struggling or something, then drop the hint, I wouldn't have jumped the gun with the anagram hint before anyone had even commented. Furthermore, the anagram was immediately obvious to everyone and is very clear, I don't think such a hint would be necessary from OP at all? -1 for them being the same person.

3. Watashi never denies being Blockladder later on in the thread though. Maybe he enjoys people thinking so? Maybe just doesn't care? Maybe missed the posts about the connection? Not sure...but I'll give it a +1 for them being the same person.

4. If Watashi is OP in disguise giving hints, the hints are super bad. I'm sorry, but it's true. The anagram was super obvious, and the image posted later didn't contain much. I ran it through steganography analysis and didn't find anything hidden in it. Despite another user pointing out the coincidences between the image post and the bitcoin mailing archive, I don't think the picture amounts to anything (Although...why would Watashi take the time to create and post such an unsolicited image? And if Watashi is OP, wouldn't he know that an image clue coming from Blockladder's account would be a million times more significant to us hunters?) - 1 for them being the same person.

Conclusion: I do not believe Watashi and Blockladder are the same person. Perhaps they are both technical geniuses however, and perhaps they are friends, given how they comment in each others' threads as discovered by f8man. It would be kind of psychotic for Watashi to comment on his own threads as Blockladder outside the context of a riddle, no?

Part 2: The Question

1. Could the answer be something obvious in the question? For example, could "21 teeth" mean the number of straight edges of letters or something like that?
2. Why is the question phrased as such? The correct grammar for the question is any of the following:
              
                Why DOES The Comb of Natasha Otomoski HAVE 21 teeth? (Where Natasha is the owner of the comb).

                Why DOES the COMBINATION of “Natasha Otomoski” have 21 teeth? Implies the subject of the sentence is the combination of the letters/words making up “Natasha Otomoski” i.e reorganizing the order of letters would somehow yield 21 variations or teeth or SOMETHING.

                In statement form, the grammar checks out. E.g: This Is The Reason Why The Comb Of Natasha Otomoski Has 21 Teeth. However, this discards the question mark at the end...so there must be a reason OP deliberately used this spelling, and in question form. The words must have been very carefully chosen, perhaps in order to be transformed into the solution later? In other words, phrasing the question in the correct grammar would yield the incorrect solution if we solve it using the mysterious method OP has in mind.

Part 3: The ".txt"

1. The .txt might not mean the white paper at all. Perhaps the sentence “WhyTheCombOfNatashaOtomoskiHas21Teeth?” is supposed to be decoded into a filename. The file then becomes “filename.txt”. Perhaps this could be searched for online, and inside it contains the private key or the 8 word 32 char answer.

2. The .txt might be a hint to converting chars to ascii codes during the solving process, or to use plaintext directly?

Please help me expand upon the .txt theories, it might unlock the secret to everything.

Part 4: The Anagram.

1. OP must’ve absolutely known that people would pick up on that anagram right away. It is the first thing that stands out and is obvious.

2. Could the code table in Watashi's first post be needed for something?

3. Could the meaning of the made up name “Satoshi Nakamoto” mean something for the solution? The following analysis of the name is from https://www.fastcompany.com/1785445/bitcoin-crypto-currency-mystery-reopened
Quote
” First, most believe that Satoshi Nakamoto is a made up name, and it seems a person as learned as Bitcoin’s creator might be tempted to choose a pseudonym that encompasses a deeper meaning. In Japanese, Satoshi translates into “clear-thinking; quick-witted; wise.” “Naka” can mean “inside” or “relationship” while “moto” is defined as “the origin; the cause; the foundation; the basis.” So we have “clear-thinking” “inside” “the foundation.

Part 5: The Hint.

1.
Quote
8 camel case english words, no special symbols.
Is this the seed phrase that will unlock the wallet? Is this merely an intermediary step that must then be converted through some kind of algorithm into the final solution? Alas, no one knows but OP.

2. It seems the hint created more questions than answers, but it is, in the end, OP's hint. So for the sake of taking things at face value, I will assume the hint is about the final answer, which will be an 8 word english phrase amounting to 32 chars, written in camelCase. Or is it CamelCase? (notice the difference?)

3. camelCase (e.g. iPhone, eBay) would result in a different answer than CamelCase (e.g. WhyDoesThe). It's worth noting, however, that OP wrote the riddle in CamelCase, with the first "W" being capitalized.

4. Idk if this means anything at all, but if we follow this:

Quote
Obviously she isn't him, but

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
S A T O S H I N A  K  A  M  O  T  O

8 2 3 9 1 6 11 4 14 13 12 15 5 10 7
N A T A S H  A O  T  O  M  O S  K I

who do you all think is she anyways?

and extract the letters at the positions of the 2nd row numbers in the original question:

1   2   3   4   5   6   7   8   9  10  11 12 13 14 15 16 17 18 19 20 21 22  23 24  25 26 27 28 29 30 31 32 33 34 35 36 37 38 39  40 41  42
W  h   y   T   h   e   C   o   m   b   O   f   N   a   t   a   s   h   a   O   t   o   m   o   s   k   i   H   a   s   2   1   T   e   e   t   h   ?    .    t    x    t

we end up with:

8   2   3   9   1   6   11   4   14   13   12   15   5   10   7
o   h   y   m   W   e   O   T   a   N   f   t   h   b   C

Reorganized in ascending order, it's simply: WhyTheCombOfNat. I'm shooting in the dark guys, pls don't hate.
