I have been trying to solve the puzzle but every time I tried I got an headache. I dont know where to start and I keep on researching until I end up with nothing. I even ask some of my friends who are good with this things but I cannot understand fully their explanation. I guess I will stop doing the challenge and will focus on the signature campaign. Well good luck to you guys in solving the puzzle its hopeless for me.

Just a every day.

I don't have good material but keep trying ;
So good luck to everyone

Hmm.. your both messages look like you are asking to increase the bounties again Wink

For example from 0.64BTC up to 6.4BTC for wallet #64 and so on

No just don't give up , we all know that is too hard, and all end up got an headache because its look like impossible, but if you have material so you can do it, I tried all this week from morning to night to find it but still nothing, because even minimze rang of search its still will take months to finish. I don't have good material but keep trying ;
So good luck to everyone

Why is 45% -55%? If you take the data from the table excluding the first ten keys. Then we get a minimum value of 31% and a maximum of 68%.

45-50% is my guess based on the analysis and statistic logics. The first keys are not representative due to higher dispersion, so it is better to exclude not 10 first keys but at least 15, of even 20.

The idea is that "the higher the bit --> the tighter dispersion". As the probability of 1 or 0 bit is always 50% for every bit, so the total quantity of "1"s (or "0"s) will tend to 50% in higher bits keys.

Quote from: mrxtraf on October 21, 2019, 05:50:25 AM

That is, the search difference will be in the range of 31% -69% of the bits set to 1 or 0.

Such "wide" range could be applicable only for low bit keys. But for higher bit keys the dispersion will be narrow.
Try to flip a coin 100 times --> more likely you will have at least 45 Heads but not more than 55 (the same for tails).
You can not take the results from the "10-15 times" coin flips and apply them to the random number where you flip the coin 100 times. No, the "heads" probability (number of "1"s) will tend to 50% while you increase the quantity of flips (bit value of the key).

Of course, everthing is possible, even the key with only 10% of "1"s, BUT morelikely for high bit keys the quantity of "1"s is within 45-55% range. Moreover, for keys higher than 140-150bit, i beleive that the quantity of "1"s is 46-54% or even 47-53%.

PS. All these calcualtions could be proved mathematically with the certain level of assurance.

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

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

This script generates a binary value according to the tips of MrFreeDragon
he puts from 29 to 35 "1´s" in binary

But actually these tips are not very big help. Even if they are correct, the decrease in total number of combinations is not too much.

For example, for 64bit key the total range is 2^63, if we take only the keys with 29-35 quantity of "1"s , so the total combinations to test is 2^62.23 (total decrease of the range less than twice).
If we limit our range to exact 32 "1"s (32 "1"s and 32 "0"s), so the total amount of combinations will be 2^59.58 (decrease approx. by 10 times)

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

those are intervals to search in ? because didn't really understand about 29 and 35

netlakes - I made a php script to generate these results

What to do with your script?
What good is it?
How can he help us to find new keys?

This is the result after using Kangaroo ..

Please any one know how can I use Kangaroo ? is it bruteforcing ?
Please someone can poste just easy tuto of using it to bruteforce, and thanks

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:

the only pattern that I get, is after 4 privatekey ,the 5th start with 1
and always and at Hex (A,B,C,D,E,F) ,more time of F and E
but its not something the was sure to use as basic

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.

Code:

No. K%rng 1's 0's %1's Private Key in BIN
01 100,00% 1 0 100% 1
02 100,00% 2 0 100% 11

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%

No the creator have stated it's random, so basicly what this means is that wallet64 key is to be found in the range = 0x8000000000000000:0x10000000000000000

This puzzle is very strange. If it's for measuring the world's brute forcing capacity, 161-256 are just a waste (RIPEMD160 entropy is filled by 160, and by all of P2PKH Bitcoin). The puzzle creator could improve the puzzle's utility without bringing in any extra funds from outside - just spend 161-256 across to the unsolved portion 51-160, and roughly treble the puzzle's content density.

If on the other hand there's a pattern to find... well... that's awfully open-ended... can we have a hint or two? Cheesy

I am the creator.

You are quite right, 161-256 are silly. I honestly just did not think of this. What is especially embarrassing, is this did not occur to me once, in two years. By way of excuse, I was not really thinking much about the puzzle at all.

I will make up for two years of stupidity. I will spend from 161-256 to the unsolved parts, as you suggest. In addition, I intend to add further funds. My aim is to boost the density by a factor of 10, from 0.001*length(key) to 0.01*length(key). Probably in the next few weeks. At any rate, when I next have an extended period of quiet and calm, to construct the new transaction carefully.

A few words about the puzzle. There is no pattern. It is just consecutive keys from a deterministic wallet (masked with leading 000...0001 to set difficulty). It is simply a crude measuring instrument, of the cracking strength of the community.

Finally, I wish to express appreciation of the efforts of all developers of new cracking tools and technology. The "large bitcoin collider" is especially innovative and interesting!

Hello, how do you launch bitreck on several cards at once?

I really don't think that is possible with the current releases, if so someone have their own build i think.

What I do is simply run another instance of Bitcrack in another CMD window, you need to run cudaInfo.exe before to know what ID each card have.
Running more instances requires some tweaking to your parameters, as the Bitcrack application sometimes (under initialising) can get an error, i think this is a memory issue, so you need to scale down parameters for each card a bit, and test that it runs properly
