#63 - 1NpYjtLira16LfGbGwZJ5JbDPh3ai9bjf4
Hex PK: 0000000000000000000000000000000000000000000000007CCE5EFDACCF6808

62 is still in progress ... I just found 63 faster :-)

What do you use for searching?

Same as previous keys found by me (#59,#60,#61) - the key was found with the BitCrack application
Interesting, what speed you have on what video card? I have rx560oc and reach only 50Mkey/s acording my calculation if you scan all 62 bit range is so much years. Are you scan small pieces of 62bit range or all ? Thanks


Edit: Sorry for my bad english,it isnt my native language.

For searching for keys I have adapted Tesla working cards that I have at my disposal in the company (which also means no energy costs). I scan the given space in full, and the total speed with which I carry out the search process is 37 200 000 000keys/s (no ... I don't do mistake... is this thirty seven trillion two hundred million keys per second)

My calclulations :
63 bit key all combinations = 9223372036854775808 2^63 ?
for 1 day you can calclulate  3214080000000000 keys
9223372036854775808/3214080000000000  = 2869.6771819166840302668259657507 days
Am i wrong  with calclulations ?

Are you use something like pool for all videos or what ? I have some ideas for adapting bitcrack to pool , but i think its useless because we dont know is it have more puzzels like this or more adresses like this for bruteforcing. I try to brute 86 but with no sucess still.. I get only 50Mkey/s even if i clock my video.....

Edit: how much cards and what period of time to brute 63 ?

Hitting # 63 was an extraordinary happiness because I used the last remaining resources to start searching # 63, starting from the end. After three days - I found ...
Responding: it took me three days to use 5% of all my power.


[/font]
Privat key in 97.5% position in own range. You found him for 3 days. 1 percent for 1.2 days. Calculate, and gette d for checked all range fro 63 bit you nead only 120 days. But if calculate your spead we get 2869 days. How?
And as far as I remember, BitCrack cannot count in the reverse order. "--stride -1" not worked. How you strating from the end?

I can understand  this puzzle wallet not in Ethereum,
But i think Vitalik can seize the funds from any ethereum wallet whether it's in trust wallet or any other wallet, he can seize the funds if the coins are earned by stolen/hacked is not it?

Don't know.  Don't care.  You are in the wrong thread in the wrong section, probably on the wrong web site. 

Since your posts are about Ethereum they are off topic and will be reported and deleted.

Your complaint/discussion belongs on an Ethereum related web site.

so nobody could crack the 62th address, it took so long this one, more than couple months

Maybe Satoshi created the greatest prize competition and the privatekeys are somehow within the blockchain.

how do you know that for sure? that it is not?

as we already know bitcoin puzzle wallets are randomly chhosed by the creater
how do you know that for sure?

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!

Drotika: you can give me proof and solve the puzzel what i made for you with this tool what you sell.
i generate a 74 bit address tell me the priv key and i will buy instantly.
here is the compressed pub key.

This might be a sockpuppet account. So catpatkany might be same person as drotika. So be careful guys!
If a mod could check this (IP?) please. Looks shady.

I ask him for same.

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?

Well, lets wait until someone beyond Newbie post a new 74 bit address generated to test Drotika's tool.

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

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.

See:

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 |
1207 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.
