no, that is not called "brain wallet".

I thought all you needed to do was find an 8 word sentence and then use this to find the private key:
https://www.bitaddress.org (click on brain wallet, paste your sentence)

I'm wrong then?

i'm afraid that only the starter of this topic can answer that question and to be honest this doesn't seem like a serious puzzle to me. ~~at least not until he provides a proper signature (the one in OP is missing the message so there is no way to verify it).~~
my assumption was based on the fact that he said "32 characters" and as i explained before 1 char is usually 1 byte. and private key is a 32 byte integer.

edit:
the message is the post itself and the new lines are \n instead of \r\n which is why i couldn't verify it first.
also here is its public key:

I do not understand why there are some people making new sensation by making puzzles to get 1 BTC, what the purpose ?

I think there are many ways to get 1 BTC, that is by trading, or by investing, or by joining ICO and Bounty.

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

As far as I know, there is no 32 character private key. A mini private key would have 30 characters.

usually every character is represented as 1 byte and considering a private key is 32 bytes you can simply convert a 32 char long string to a 32 byte long byte array and use it as a private key.
for instance this sentence ("Hi this is satoshi nakamoto comb") is 32 byte long and can be represented as "10f0c810a0c56a1282574ce4bf9d3e843afc5be688c277ab75e6da1e6f95d756" in base16 or "Kwne8vNfRRiq8d6CB6YpCtbK6EKCRyoCjPGomLshKgubBWwiDQWD" in base58 WIF.

That's called a brainwallet: https://brainwalletx.github.io/

no, that is not called "brain wallet". it is not called anything actually. you are choosing the private key in a silly manner, that's all. a brain wallet has no restrictions for how long the input should be (the 32 byte) so it can be a 1 letter input or an essay of couple of pages long. and that is simply because they hash it to reduce the size.

lol, i don't know why but i was passing the SHA256 hash of it as the bytes instead! fixed it

SEND AND RECEIVE MONEY INSTANTLY

Obviously I'm not sure how serious this offer is. At the end of the day someone gets the Bitcoin in his wallet, saying that I've done it.

How do we know that the person who opened the thread didn't do it to collect appreciation?

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.

My guess,
So based on this thread, Natasha Otomoski probably Satoshi Nakamoto, number 21 probably max supply of btc, based on coinmarketcap max btc supply is 21,000,000 which is have 21 too.
It is possible to turn the question into "Why Satoshi Nakamoto Create bitcoin with 21 million supply?", Its pretty similar tho, "Why The Comb Of Natasha Otomoski Has 21 Teeth?" , but idk, just guessing.

I can only guess he means it is a brainwallet mnemonic. Don't mind giving additional hints, I've given up guessing... A couple parts that threw me was the anagram of Satoshi Nakamoto and the fact that it ends with ".txt"...

"WhyTheCombOfNatashaOtomoskiHas21" itself is 32 characters long and consists of 8 words... Hmm...

8 camel case words is so easy to find but fitting it in 32 characters long is too hard. Lol
By the way i don't want to waste my time on this puzzle. Kindly show first your proofs that you own that address .such sign message like what kakmakr said.!

By the way, why would you bother mentioning you don't want to waste your time? Given by the profile's unusual post history, I would venture to guess there's at least a 50% chance this is legitimate.

Fitting it in 32 characters isn't too hard, see?

It Has One Tooth For Every Million Btcs

That's my best guess, and that's not it. I'll let some new people find this thread and work on it with this incidental bump.

Are you going to place the 1BTC into escrow or do you have a signed message that you own the 1 BTC for this prize? The address 179sxfh6rw6bHSo5wVUhLP96k46QaEzVP might have 1 BTC, but who says you own it and that it is accessible by you and that you know the Private key for that Bitcoin address?

Let's have a signed message from that address please, showing that you own that address and that you know the Private key, before we put the effort into this. Roll Eyes
