Anyone ever have any more luck here? I’ve tried a bazillion combinations in brainflayer, and even went down a rabbit hole with Peter Norvig’s “big.txt” file... (it comes up when you google the full phrase). If anyone wants to work together, let me know. Could very well be a troll, but after working on these pineapple arcade puzzles, this looks like it should be easy (spoiler—it’s not).

[racminer]

 
It could be that ?.txt just means that we are seeking a text. The hint just confirms that.

Theeth = 1 Million BTC
Comb   = Combination
NatashaOtomoski = Satoshi Nakamoto

One possible answer is:  because every four years the 50BTC block reward is halfed ( 128 years, you can't half one satoshi)

Put that info into a 32 character 8 camel case english words, no special symbols

Answers may look like this:

EveryFourYearBlockRewardIsHalfed

If this helps I accept a small contribution from whoever gets the 1 BTC ...

[jajorda23]

I don’t know if any of you have read “Duality” by the supposed Satoshi, but here’s a quote:

For starters, many may wonder what the reasoning behind the fixed supply is. 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.

The educated guess bit seems like a possible answer, but I couldn’t draw any valid permutations.

The educated guess bit seems like a possible answer, but I couldn’t draw any valid permutations.

It's obvious that 21 million is related to the concept of halfing the reward value. In math it is called sum of geometrical series terms.
If you start with a number Q and you sum the folowing terms
S = Q + Q/2 + Q/4 + Q/8 + ...  = 2 Q 
see here :  https://en.wikipedia.org/wiki/1/2_%2B_1/4_%2B_1/8_%2B_1/16_%2B_%E2%8B%AF

Satoshi took Q=210000*50 and obviously 2*Q = 210000*100 = 21000000


 

[kachev87]

I read the Duality.pdf  and I saw the part with the ''educated guess'', tried different combinations, but again no luck.
From the last 3-4 posts I think that the hint given by the Puzzler a ""solution" is not an actual answer to the question "WhyTheCombOfNatashaOtomoskiHas21Teeth?.txt".
We are all seeking for the "solution", but first what is the "answer"?
I`m thinking that the "solution" 8 camel cased words are something like an anagram to the "answer".
But I personally don`t have any ideas what the answer can be or the connection to right 8 camel cased words that are the solution.

HI,
I tried 

NatashaOtomoskiIsSatoshiNakamoto
SatoshiNakamotoIsNatashaOtomoski

No luck.
I think we should convert each letter to its ascii and then create key directly from that .
so NatashaOtomoskiIsSatoshiNakamoto  becomes   5JQoiBW5eKd6gFvakcX2mJmCmKgJJsbRvDbVzcfeUaYqJGzDUXn
(as suggested in various previous post )
I don't think we need Brainwallet.

I think that there are a few important clues:
- the '.txt'  at the end is a clue I think but I don't know to what?? (I treid to save a file with that name but got : 'A file name can't contain any of the following characters: \ / : * ? < > |')
- The anagram NatashaOtomoski  suggests to me that the name SatoshiNakamoto  should be in the answer.
- the 21 which seems to point to the max number of bitcoins. Or what else
- then there is the strange 'COMB'. I see no connection to Bitcoin there.  (unless you comb the knots out of  'NatashaOtomoski' to get 'SatoshiNakamoto')   ToGetOutSatoshiNakamotoInTheEnd
- and the curious start transaction to fill up https://www.blockchain.com/btc/address/179sxfh6rw6bHSo5wVUhLP96k46QaEzVP. Should we check out the orig. adresses further ?
  (if you look at the adresses.. you see quite a history of small tranactions.)

And it could also be that there is no solution (trolling ?? ).

Intriguing

[runlola]

- The anagram NatashaOtomoski  suggests to me that the name SatoshiNakamoto  should be in the answer.

That would invalidate the hint: "8 camel case english words, no special symbols". "Satoshi" and "Nakamoto" are not english words, and if you do include them plus 8 additional english words, those words would have an average length of 2 characters/word. So very unlikely.

- then there is the strange 'COMB'. I see no connection to Bitcoin there.  (unless you comb the knots out of  'NatashaOtomoski' to get 'SatoshiNakamoto')   ToGetOutSatoshiNakamotoInTheEnd

COMB is an abbreviation of combination(s). Seems very relevant here.

[seoincorporation]

- the '.txt'  at the end is a clue I think but I don't know to what?? (I treid to save a file with that name but got : 'A file name can't contain any of the following characters: \ / : * ? < > |')

the .txt could be a reference to the whitepaper, i think that the last time i try to solve this puzzle but could not find the answer on that document, maybe we could try some brute force with the whitepaper words.

[GBT_User]

Thanks for your reactions, I read the whole discussion and I saw these remarks before.
But the whitepaper did not really get us anywhere so far, and even I would not know how to bruteforce that.
The Comb could be an abreviation, I think, but only "Might-be"  imo.
And the names not being english words, also a "Might-be"  imo.

I will keep trying but I think if this is a real Puzzle, and not a fake, we need some more hints.
Good luck all

[troslky77]

Hi, I see the puzzle isn't solved yet so I just found a nice generator imho that can help to create something closer to the answer.

Here's the website >> https://xkpasswd.net/s/

On the Top "Words" we have to select "number of words" of course 8, then minimum and maximum "4 " in this case to get 32 characters plain text.

Below in "transformations" mark "Case Transformation as "Capitalise First Letter"

And the rest of settings we should to unmark ( set none for all )

That's it!.

We can now generate maximum 10, 32 characters passwords, I know it's not corelated to the puzzles but who knows, maybe it could help too.


Also I have a interesting site too >> http://bitcoin-brain-wallet-cracking-tools.ga/

Just paste our passwords in section "ADD PASSPHARSE" and click "START" - the site will automatically check all the passwords very fast and give output with a list of adressess with or without the amount.

Good luck (:

[troslky77]

I really don't know are we going into the right side but just open this page http://titlecase.com/ .

There is no "CamelCase" but "camelCase" - what is interesting, author said "camel case" what is suggest me a "camel case" text as a lowercase...

The "Case" which are we looking for is called "PascalCase" on the site above.

These first big letters "WhyTheComb"... are for an easy read only imho...

Really weird

[ryap12]

I can't believe nobody has yet to figure out the private keys. Looks like this is a really difficult puzzle then. I have seen a lot of attempted solving it with different strategies and understanding. And looking on OP, he or she has not login using the same account. It could be an alt of someone who actively uses bitcointalk but who knows? Everyone wants more clue and hoping he or she gets to read this and adds another clue.

this may be bullshit, but out of curiosity i entered "hal finney comb" into google and got one hit:

However fine tooth comb is not one with 21 teeth on it

Unfortunately I can't be puzzling for much longer because I go to work tomorrow.

I saw above reply a few days ago and said myself: "way should someone search Hal Finney instead Satoshi?". the answer is because some people believe Hal Finney may be real Satoshi. then I said myself again:"what if this user(watashi-kokoto) be blockladder(OP)?", then each of him/her replies may be a clue for us.

His first reply decrypt an slice of the puzzle for us:

who do you all think is she anyways?

and this reply implies to a Mailing List Archive that includes some mails of Hal Finney:

and in this reply he have a mistake about comb teeth number(20 instead 21):

Every puzzle needs an art piece so I shooped something hope you like it.

EDIT: fail. 20 teeth not 21 I'm tired

EDIT2: fixed

all of these clues are in Bitcoin Mailing List Archive. in this Link you can see a mail from Hal Finney to Satoshi that he mistakingly mentioned the total number of Bitcois 20 milion:

Code:

Congratulations to Satoshi on this first alpha release.  I am looking
forward to trying it out.

> etc...

It's interesting that the system can be configured to only allow a
certain maximum number of coins ever to be generated. I guess the
idea is that the amount of work needed to generate a new coin will
become more difficult as time goes on.

One immediate problem with any new currency is how to value it. Even
ignoring the practical problem that virtually no one will accept it
at first, there is still a difficulty in coming up with a reasonable
argument in favor of a particular non-zero value for the coins.

As an amusing thought experiment, imagine that Bitcoin is successful and
becomes the dominant payment system in use throughout the world.  Then the
total value of the currency should be equal to the total value of all
the wealth in the world. Current estimates of total worldwide household
wealth that I have found range from $100 trillion to $300 trillion. With
20 million coins, that gives each coin a value of about $10 million.

So the possibility of generating coins today with a few cents of compute
time may be quite a good bet, with a payoff of something like 100 million
to 1! Even if the odds of Bitcoin succeeding to this degree are slim,
are they really 100 million to one against? Something to think about...

I think  the solution of this puzzle may be in the content of this mail.

And this makes me thinks that who is this blockladder guy? He could be "Satoshi" too right?  If we browse through the guys' past he created the account on the year 2015, and now he just wants to give us 1 whole BTC to solve the problem year 2019. That's a 4 years gap to post, so I believe that OP is someone really special connected to Satoshi.

[tortic25]

I think i was on the right track yesterday but no luck, here's some thing ive found.


Satoshi Nakamoto 21
i focused on these 3 thing because they all seem to be clues.

the 21 could mean 21 pages from a book claimed to be by satoshi nakamoto
https://bitcoinexchangeguide.com/nakamoto-family-foundation-book-gets-stylometry-test/

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?

the books name was hidden in a cryptogram like the one above

so maybe use the cipher text alphabet provided on this page to decode it somehow


 


another less likely one.
WhyTheCombOfNatashaOtomoskiHas21Teeth?.txt

i focus on the .txt
the ops first post links to github and  the .txt is a pgp public key. that only gives you an email address to the op
so maybe you send him the question and wait for a response "8word passphrase"

all i saw was the public key, and a signed signature.
there was no private key, or message. but yesterday was my first day using pgp so its likely i missed something.


-------------------------------------------------------

[Mux@]

A good puzzle and a worthy prize. For months no one can find the answer! I will try to break my head over this task. If You see that 1 BTC is missing, then I have solved the puzzle

[Wendigo]

I am pretty positive I have found the correct answer to the puzzle. Figuring out the key words now.

[codehtcmail]

Ok, here's a 1BTC puzzle.

The question is the following:

WhyTheCombOfNatashaOtomoskiHas21Teeth?.txt

The solution is a 32 characters long plain-text (the private key).

Hint: 8 camel case english words, no special symbols

Happy puzzling!

G/cbms/K/DNzcRin5v2B03iXdbpdVoZbTebt7KG95j3FUqnJvcP9rDYcGpSV27RLspR7SlPjqma4h0tDAMwovIo=

txid 39ae730abf9190f1985a3600e35b6451efc51bfb885bc9d1c3b91d502de3907d

If I take it in a simplistic way, the solution IS the priavte key.
I also noted the message has 8 lines in total in it while the hint says "8 camel case english words, no special symbols" a link maybe?
I am also VERY puzzled by the .txt part.
