Ok, here's a 1BTC puzzle.

[pooya87]

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.

Hex should be: 48692074686973206973207361746f736869206e616b616d6f746f20636f6d62

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

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?

[airdagon]

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.

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:

that's incorrect. the OP used the post text as the message and it validates.

[runlola]

i wonder if OP was giving us another hint by giving the txid instead of the address. it looks like one of the addresses in the tx might be a vanity address: 1BucK...

i tried verifying it yesterday and it didn't verify (using Electrum). however it is possible that i've made a mistake since it is not in code tags which makes the copying a bit weird. i'll try checking it later and if it verified i'll edit my previous post.

[Peter88]

Signature is valid (try quoting a reply and copy the post message from there)

nice puzzle btw! Will there be any hints regarding the direction?

[Thirdspace]

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.

true... the OP has a valid signed message
but I can't figure out the answer to the question or any lead to finding the private key
and what does he mean by "8 camel case english words"?
nevermind... I understand what it means now

I think I get it, just many combos to go through.
No acronyms, right? Full english words?

Uuumph, too hard for a regular trader!

I'm curious, does "Hint: 8 camel case english words, no special symbols" mean no numbers(as in numeric symbols)?

[Thirdspace]

I'm curious, does "Hint: 8 camel case english words, no special symbols" mean no numbers(as in numeric symbols)?

camel case means writing sentence/phrase with no spaces and punctuations, special symbols = @#% etc
instead of space between words, a capital letter indicates a beginning of a new word
for example, weDontKnowTheAnswerToTheQuestion
I'm not sure whether in this case the very first word should begin with lower or upper case letter

[HippiePyro]

I believe it would start with a capital letter, as that is part of CamelCase style, and how the OP wrote it

Yeah, I know, I mean is smth like "ItTookForeverButYourCodeIs234567", that has numbers, possible? Because numbers as numeric symbols are not actually words. And it says english words.

Thanks. Comes in very handy.

the average (4 letters per word) is really really low.
according to some site 8.23 characters is the average length in english this means if the solution originated from normal english, the author was
mainly removing words that were pointless or too long, to fit it correctly.

distribution: since in english there is many shorter than average words and rare longer ones, so would be in the puzzle.

because 4 is the average this means three letter words are extremely likely, they act as counterpart to the longer than average words

What three letter words do you think there are? Most common are:

 one, how, the, out, had, was, for, use, and, can, her, are, she, all, you...

I was trying to come out with obvious combos involving 3+4 letter words
