 Wink
understand!
But either way, all tips should be tested;)

I use bitcrack, with this tip, I can create starting points.

29-35 is the amount of 1´s in a binary number.

This script generates a binary value according to the tips of MrFreeDragon

he puts from 29 to 35 "1´s" in binary

bounty0z, there was no some pattern. All the keys were random.
However, i made some analysis of all the private keys for the "opened" wallets, and can say that more likely the key has the following property:

Quantity on bit "1" in the key is 45%-55% from the total bit quantity

This means that for the wallet #64 the total quantity of "1"s in the key is from 29 to 35 with the leading first bit "1" (first bit is always "1" for all keys in the puzzle). To increase your chances youl should take 29-35 "1"s, randomly mix them with the remaining "0"s and you will receieve the key. The key consists from let's say 10 "1"s bit and 54 "0"s bit is not the key for #64, as here only 15% are "1"s and the majority are "0"s.

How did I receieve this? I had a look at all the private keys in BIN format, and found that the average quantity of "1" in all the keys is 51%, the total range is 40-60%, but the most likely is 45-55%. Please have a look at all the known private keys in BIN formmat and the calculation of "1"s and "0"s in them.

AVG 53% 51% Average for wallets > #15

Keep in mind that the fist 15 keys are not representative due to small length, so the average is  calcualted for wallets greater #15.
Additional analytics for information purposes (i did not find any patterns here): K%rng is the actual private key range point (in %%). It means where the actual private key was found in the context of total range (0% is the 1st point of the range, 100% is the last point of the range). K%rng for wallet #n is (PrivKey(n) - 2^(n-1)) / 2^(n-1) * 100%


Cool!

Hi!! Is it easier to break an address with the public key? could you explain to me which method?

I need public key for non find number .. 64, 66 etc Grin nobody help my?

1) ‘Why The Comb...’ is poor grammar (it should be ‘Why Does The Comb...’). I assume this is deliberate (OP appears to have native English), and that ONLY these letters are required.

2) I assume it’s an anagram of the question for that reason.


I had not thought of that before, but it makes sense ...


I'll post my thoughts so far here. They may or may not be useful - I hope so.
It looks like blockladder has deleted posts he made in the past. A Google search shows up the odd quoted post for which the original has been deleted. It's hard to tell whether these are sarcastic or trolly. Either way, I've hit a dead end. Here's what I've assumed so far. Some of these assumptions could be false, of course.

Thoughts/Assumptions
1) ‘Why The Comb...’ is poor grammar (it should be ‘Why Does The Comb...’). I assume this is deliberate (OP appears to have native English), and that ONLY these letters are required.

2) I assume it’s an anagram of the question for that reason.

3) The ‘.txt’ is difficult; it could be part of the answer, or could simply indicate that the answer is plaintext. Including ‘txt’ increases the proportion of consonants to a problematic level.

4) I assume that the 8 camel case words are to be hashed (SHA256) to create a 32-byte privkey. It is technically possible that the 8 words ARE the key. However, this would require that several letters were discarded (as the question contains too many), and there is no obvious indication of which ones.

5) ‘Natasha Otomoski’ is an anagram of ‘Satoshi Nakamoto’. The letters were clearly grouped to indicate this, so I assume ‘Satoshi Nakamoto’ is a part of the answer. This massively reduces possible permutations for 8 words. If it is not, and is simply deliberately misleading, it becomes vastly more difficult to figure out the answer.

6) There may be a second layer in the puzzle, whereby the answer references something in the question rather than just using its letters. ‘Why….?’ implies an answer ‘Because...’ (the right letters aren’t present though) or ‘To...’  I spent a while considering the joke, ‘What has teeth but cannot chew’. Answer: A comb. ‘ToChewThe21MbyteHashOfSatoshiNakamoto’ doesn’t hash to the given address.

7) The significance of ‘21’ (or ‘12’, or ‘1’ and ‘2’ separately) in the answer is unclear. The letters aren’t present for ‘21 Million bitcoins’, though they are for ‘21m Btc’.

Cool A rail fence cipher doesn’t appear to produce anything useful.

That's all from me. It felt I was getting close. Assuming there is a solution, I hope this helps someone find it.

that ".txt" at the end of the question should have some meaning

The English dictionary has 171,476 words.

finding 8 words in 171k and still in the right order with 32 characters is very unlikely anyone can solve.

I think there's more chance of winning the lottery than solving this puzzle.

Right. Either the 8 words are the privkey (which is possible if OP did some brute forcing - I've done something similar myself, several years ago now, for a puzzle), or it's a hash.
Either way, it's finding the right 32 chars. I have been assuming that they are from the question itself, like others have been.
Why would that require brute forcing? Huh

You "simply" pick 8 words that total up to 32 chars as your answer: WeCreateAnAnswerThatIsEightWords

Then pick whatever method you like to use that as your private key:

char->hex method... which yields private key: 5765437265617465416e416e737765725468617449734569676874576f726473 (18LpdmS7UPHRPsNmD384LRRawHjVXprJy1)
or
brainwallet (sha256) method... which yields private key: 8EAFEFFE8CEE0E1E43A53314FFEC31BE09B378A4E733A516BBBAEB177CC151FD (15idakESXkA4N5Uyjts2xTFupBLD9Pibz2)

You can then send your XBTC prize to the address you just "created" Wink


The problem we have is that there is no definitive answer as to whether we should be doing "char->hex" method or "brainwallet" method. I guess the solution to that problem is to simply check both! Wink

I fully agree

I think you're mistaken, if you insert a camelcase phrase it generates the hash respecting uppercase and lowercase letters.

https://brainwalletx.github.io/#generator

just insert your guesses into the passphrase field that it will convert to an address.




I feel close. I have a solution that matches the right criteria, with the double meaning implied by the question. Just need to figure out how to process it.
ablosulty wrong way- brainwallet words is a SMALL case begins! not a @CamelCase

I've tested thousands of possibilities, I've given up on this challenge

Has anyone been able to verify the signature? G/cbms/K/DNzcRin5v2B03iXdbpdVoZbTebt7KG95j3FUqnJvcP9rDYcGpSV27RLspR7SlPjqma4h0tDAMwovIo=
I could not, it always gives invalid signature

I'm pretty sure it's troll.

Rooting for you guys, I hope its for real and someone here solves it. Smiley

Annoyingly, I've hit a dead end.
I'll give it a while longer, then post my thoughts here in case they're of use to anyone else.
13  Economy / Games and rounds / Re: Ok, here's a 1BTC puzzle. on: March 06, 2019, 03:12:28 PM
from what I understood, the 8 words in camelcase form 32 characters and then sha256 (8words) forms the private key

I made a javascript script to test multiple combinations with 8 words that add 32 characters and did not succeed, several people tried it, this tool is very good for testing https://github.com/dan-v/bruteforce-bitcoin-brainwallet

I don't think it's a troll - I'll give it a little bit more time and then, if I can't solve it, drop my thoughts here.
When you have enough letters to play with, you can make it fit (almost) anything. But the answer I've got so nearly fits the criteria, and reflects the principle hidden between the lines of the question very neatly (I can't say more without giving it away).
But I cannot figure out how it's slimmed down to 32 letters. I am missing something.
Thank you for the tool.

Thanks - BitAddress does the same if you enter a non-valid private key. I've been using that.
It's not clear from the question whether the solution to the riddle is the private key itself, or whether it points to the private key. I don't think it will make too much difference either way but would help - knowing if the answer is 32 letters or not would be useful.

Hello, I just registered here.
I`m trying to solve this puzzle from a week now and I tried
everything that came to my mind.
Tried to search for answen for:
Why Satoshi Nakamoto made bitcoin amount to be 21 million - no eight english words answer
Why combs have 21 teeth - no eight english words answer
What is the meaning of the number 21 - it is the sum of all first 6 natural numbers - matematics, Fibonacci,
spritual, what so ever involves the number 21, 21 century stuff, I tried and tried.... and no luck...

I don`t think that even Satoshi Nakamoto(or Natasha Otomoski) can answer that question.

I wish you people luck to crack that puzzle! Smiley



This puzzle I suppose requires some technical workaround in cryptography.
I've tried hashing the question into a sha256 and minus the transaction hash no eight english words there.

This riddle or puzzle is extremely difficult to solve, but I think it is only a matter of months anyone would solve this.

knowledge of cryptography is only a secondary requirement and it will only be needed in the last step, if at all. the first step is to understand the puzzle question and have a starting point instead of making guesses and/or brute forcing random words to get something out of it.

at this point i am convinced that this either was a trolling attempt considering overall activity of OP or if it is an actual puzzle, it was very poorly designed which makes it impossible to solve.

total waste of time.

it is clear that it is a troll.

You, stubborn boyz, don't get simple thing: bounty is 100% compressed, so you need only -c switch.
For abandoned wallets you 100% need both -u and -c switches.
That's 2x drop.

bloom filter with thousands of addressed also cannot be free. Here you get another ~50% drop.

So, 1 address vs thousands is really around "3X difference".

Ok

We "stubborn boyz" have shown you numbers not expectations.

Thank you for you very competent comments.

Welcome.

I claim that an Rx480 does 105MHkey/s on 01 target and 85 MHkey/s on 2,749,473 targets (compressed only)... draw you own conclusions. This is no BS.

1. Most abandoned wallets are uncompressed.
2. If speed with one address is almost the same as with 2.7M, then you haven't found right values for -b A -t B -p C
No other options.
8Gb Rx480

-b 72 -t 256 -p 2048

Most abandoned wallets are uncompressed .. you are certainly right.



my rx480 4gb config:

-c  -b 72  -t 256 -p 2048   

5,000,000 addresses = 85Mkey/s

-c -u  -b 72  -t 256 -p 2048   

5,000,000 addresses = 42Mkey/s

hello guys, today this wallet appeared 1JMT8uyrnVAvkhiexbTL9dyyMwTqjKygU9
in my search

take a look at the transactions, can anyone explain what this is?
20  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: February 24, 2019, 11:55:39 PM
Woah that https://www.blockchain.com/en/btc/address/1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF?offset=250&filter=6 address is filled with $300 million!
I thought this whole riddle was about 32 BTC?
Btw I am not into this cracking kinda stuff enough to participate into this. Just clicked through the posted addresses in this thread and found this HUGE wallet which a user above me posted.
 
Insane.  
I guess if this key is crackable, the reward is so insanely high because it is nearly impossible to crack.
I'd love to know the guy knowing the result to this riddle and get to know how to solve this lol. That'd be awesome.
Like "Hey dude you heard about this riddle I made with Bitcoin? You aren't into BTC anyway, so here's how to solve it...."
"Oh that sounds fun! No worries I won't participate in solving it. *Opens Bitcoin wallet and imports priv key*"  
 
By the way: Ever thought of where this huge stack of Coins might come from? Could the source be some illegal hacking stuff offering the coins for grabs via a riddle because they can't sell them anyway? (IF it is related to any riddle at all.) Could it be an exchange wallet not related to a riddle at all? Would be really interested in seeing some blockchain analysis here to get to know who owns/owned these coins and how they have been acquired. 2011 is a long long time ago.  
Or did Mark Karpeles forgot a paper wallet sitting in between his couch again?

183hmJGRuTEi2YDCWy5iozY8rZtFwVgahM;8.59473e+12


That one must be an exchange cold wallet. Transaction happened within the last 12 months also. I bet it's Coinbase. Or Bitfinex.
 
Btw

[...]e+12

not familiar with these kind of numbers that begin with "e", what does it mean?
I'm stupid I know. I'm also not very good at math. Would be happy to have explained why you wrote those "e"-numbers behind the addresses. Thanks! Smiley

hi!!

 Prism switches to scientific notation when the values are very larger or very small. For example:

2.3e-5, means 2.3 times ten to the minus five power, or 0.000023
4.5e6 means 4.5 times ten to the sixth power, or 4500000 which is the same as 4,500,000
This is a standard notation used by many computer programs including Excel. Entering a value in this form is not the same as entering the logarithm of a number. This is simply a shortcut way to enter very large values, or tiny fractions, without using logarithms

Note that in other contexts, e = 2.71828183, the base of natural logarithms. But when used in displaying large or small numbers, e means "times ten to the power of...".
