There are almost 850k combinations of 8 words that have 32 characters (like 4 2 4 8 2 5 2 5).

https://filebin.net/pko3eyxrha59wdk3

Considering words with max 8 letters.
If we remove unlikely combinations (like 1 1 1 1 4 8 8 8 ) it can be reduced 2-3 times but with hundreds of possible words for every word length, there are still way too many combinations to go through.

I think i know how to reduce the combinations. Sort it by sum of differences from 4 4 4 4 4 4 4 4. The new list looks like:

Code:

000 4 4 4 4 4 4 4 4
002 3 4 4 4 4 4 4 5
002 3 4 4 4 4 4 5 4
002 3 4 4 4 4 5 4 4
002 3 4 4 4 5 4 4 4
002 3 4 4 5 4 4 4 4
002 3 4 5 4 4 4 4 4
002 3 5 4 4 4 4 4 4
002 4 3 4 4 4 4 4 5
...

The correct solution is likely to be in top 10 000 of such a list. Maybe in top 1000

it is not hundreds it is at least billions of possibilities because when you are brute forcing it like this you don't know the sequence of the words so if you choose a result like A B C D E F G H (where a,b,.. are words) then it alone has 40,320 (8!) cases (eg: ABCDEFGH, ABCDEFHG, ABCDEHGF,...) then you have to also add the variation of each word. meaning A (if it is a 2 letter word) may be at least a couple of thousand words. and that is true for each word.
it simply is impossible to brute force this without having at least 5 or 6 words of it.

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

Did you make the puzzler? That looks a very handy tool solving this CamelCase Key.

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

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.

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

simply enter the solution into the first box

it checks the ripemd160 matches the one on blockchain.info and gives you alert window if yes.

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

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

Quote from: Peter88 on January 15, 2019, 07:16:06 AM

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?

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 Cheesy

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).

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

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.

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...
