I am the creator.

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, in which wallet should i recover the found keys (wif,hex format) , i need a decentralized wallet , so people can't seize the money even if they want,

i need solution for this please

And ELECTRUM can be a reliable wallet?
It has a "do not spend" function
Who used this function and can tell?

can anyone know, or explain to me please,

how it will be easy to find private keys which has spend transaction for the wallet in compare to wallet which hasn't spend transaction ?
please explain if anybody know , i am confused so, thanks.

When there is no spend transaction the search method is:

   Next Private Key -> Public Key -> Hash -> Bitcoin Address -> Compare Bitcoin Address, repeat until found

   Note that due to the hashing functions used the Bitcoin Address match is expected within a private key range of only 2¹⁶⁰

A spend transaction exposes the public key so when there is a spend transaction the search method is:

   Next Private Key -> Public Key -> Compare Public Key, repeat until found

   Note that the private key range in this case is the full 2²⁵⁶ but there are ways to speed up the process so the effective security is reduced to only 128 bits.

See the following:

Quote

Baby-step giant-step - https://en.wikipedia.org/wiki/Baby-step_giant-step
Pollard Kangaros - https://en.wikipedia.org/wiki/Pollard%27s_kangaroo_algorithm

So the two situations are:

Full entropy 256 bit private keys with multiple spend transactions have 128 bits of security

160 bit Bitcoin address from a full entropy 256 bit private key with no spend transactions have 160 bits of security

So Bitcoins kept on a Bitcoin address with no spend transactions are safer (160 bits of security) than Bitcoins kept on a Bitcoin address that has spend transactions (only 128 bits of security).

thanks, let's say we got a spend transaction on bitcoin puzzle wallet #120, we got hash of it, so how do we calculate with bitcrack for 2^128 possibles?

Please go back and read what I wrote way more carefully. A spend transaction exposes the public key so you no longer have to do any hashing. Bitcrack is for brute forcing when you do not have the public key. You would need/want to use one of the more advanced methods (see the links in my post) to calculate the private key directly from the public key because it will be so much faster than the primitive bitcrack program. There is no hashing involved any more since you no longer have to deal with the Bitcoin address - you have the public key. BTW there is a spend transaction on #120 so the public key for that address is in the block chain and is available. The person that solves #120 will not be using the primitive brute force bitcrack method. #120 will most certainly be solved using the Pollard Kangaros method. Depending on how much HW you can afford it will take between 116 days and about 8 years to find it.

What is your expected time for #105?

I was using 4x Tesla V100 for it. Here is a table with expected times:

|------+-------------------+-------------------| | bits | 4x V100 | 100x V100 | |------+-------------------+-------------------| | 100 | 2d 19:52:51 | 02:42:54 | | 105 | 16 days | 15:21:34 | | 110 | 90 days | 3d 14:53:14 | | 115 | 1 year 147 days | 20 days | | 120 | 7 years 341 days | 116 days | | 125 | 44 years 323 days | 1 year 290 days | | 130 | 253 years | 10 years 57 days | | 135 | 1,436 years | 57 years 166 days | | 140 | 8,125 years | 325 years | | 145 | 45,964 years | 1,838 years | | 150 | 260,011 years | 10,400 years | | 155 | 1,470,848 years | 58,833 years | | 160 | 8,320,376 years | 332,815 years | |------+-------------------+-------------------|
Looks like a "world record" would be 120 bits.

To anyone who considers buying this:
Generate a public key with the private key in the 75 bit range and ask drotika to give you the private key for this public key.

Hello to all. Sorry for previous reports about the script and high speed search. There was a mistake in the calculations. And considered impossible keys. I checked the script on the already found keys, these are the results.

Code:

16 bits - V1(Middle) - 9 seconds
17 bits - V1(Middle) - 7 seconds
18 bits - V1(Middle) - 0 second
19 bits - V1(Middle) - 25 seconds
20 bits - V1(Middle) - 157 seconds
21 bits - V1(Middle) - 323 seconds
22 bits - V1(Middle) - 43 seconds
23 bits - V1(Middle) - 1317 seconds
24 bits - V1(Middle) - 440 seconds
25 bits - V1(Middle) - 914 seconds
26 bits - V1(Middle) - 358 seconds
27 bits - V1(Middle) - 14465 seconds (241 minuts) (about 4 hours)
28 bits - V1(Middle) - 44409 seconds (740 minuts) (about 13 hours)
29 bits - V1(Middle) - 20295 seconds (338 minuts) (about 6 hours)
30 bits - V2(Direct) - 25304 seconds (422 minuts) (about 7 hours)
