Bitcoin puzzle transaction ~32 BTC prize to who solves it

WIF-Key based scanner for the 66 bit range..
 ...happy Hunting!!

your code is the most inefficient way to search the puzzle.

Your way:
WIF->Private Key->Publickey->Sha256->rmd160->Address.


Why not only?

Publickey->Sha256->rmd160

In this way you avoid some steps that need a lot of calculation.

Regards!

simple answer...
the area that is random consists of only 6 letters from the Wif-key...
and the secp256k1 from (ice) is super fast...

Speed test with 4 cores:   [ Speed : 301444.62 Keys/s ]
the calculation takes place one after the other, not at the same time, which would take time...

Using python or any high level language to do heavy computations is trouble .. cracking is better coded with c/cpp/golang/java .. but thank you a lot for sharing your code

I have 16 available cores each capable of 4.5 GHz but I get only 1,186,383.53 Keys/s when running your code. When I check utilization in top or htop I see there are only about 4 cores utilized at 100% but even then I would have expected higher rate. Anything I'm missing ?

I'm using secp256k1 from iceland2k14. When I manually set core for instance to "15" it utilizes 15 cores, but I would have expected that the cpu_count enumeration had worked. Seems it didn't, despite that ... With 15 cores I can achieve 2003121.42 Keys/s that is 2 MKey/s. You said you're achieving 600 MKey/s, how do you do that with CPU only? Wouldn't it be better to utilize GPU for such things?

I can get the same speed with only one core using my code

You are confusing something, I achieve the 600 MKeys/s with the GPU and not with this code...
for this code a CPU is working with 3 GHz/core..

..it depends on the CPU used... I have 3GHz/core... be happy, the faster the better!
but the forum is not for saying "who can run faster"

it's about innovation, ideas to shorten the search... new ways in the programming..

My CPU is core i5 @ 2.6 GHz.

Anyway if it is about innovation your code doesn't have any of them.

Your way is not the shorten way, and also is not a new way of programing.

You did not reply my question

Your way:
WIF->Private Key->Publickey->Sha256->rmd160->Address.

Why not only?
Publickey->Sha256->rmd160

Skipping the WIF to privatekey and the rmd160 to address you can save a lot of process and speed up your search up to 200% or more... Trust me I already pass for that process.

What I'm trying to write, is that you can do it better, what stop you from that slow speed? You can get a better performance from your current hardware

Good luck

I cannot get your @jolly_jocker code to run correctly.

However, I think what you are trying to achieve is using the known WIF key part and tumble searching the remaining characters to find the WIF private key. I am able to again, use the known key part and add a randomize search for the remaining part and output this in hexadecimal format. It is not any faster than a general hexadecimal search.

I am not sure if you can generate a WIF private key with a check sum and convert/compare ; and then print the WIF key again in the same script.
I do agree that this puzzle is about testing the strength and secure-ness of bitcoin with new, creative code.

This is a basic python script and variation of VanityGen:

Code:

import secrets
import base58
import binascii
from bitcoin import privtopub, pubtoaddr
import sys

vanity = "13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so"
btc_addr = ""

while btc_addr[:len(vanity)] != vanity:
    prefix = "KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qa"
    alphabet = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"
    postfix = ''.join(secrets.choice(alphabet) for i in range(18))
    first_encode = base58.b58decode(prefix + postfix)
    private_key_full = binascii.hexlify(first_encode)
    private_key = private_key_full[2:-8]
    btc_pubkey = privtopub(private_key.decode())
    btc_addr = pubtoaddr(btc_pubkey)
    
print(private_key.decode())
print(btc_pubkey)
print(btc_addr)

sys.exit()

I genuinely would like to know .. are any of these python scripts working any faster than known C programs like keyhunt or vanitygen etc? I mean the slowest I've ever seen to date was Brainflayer as it starts with pass->key->...... but to be honest i would be surprised if i see a fast python one getting the same speed as for example keyhunt .. plz post your speed results .. much appreciated

[VinIVaderr]

Using a chromebook and the python timeit module with (10000) loops.

chromeos@penguin:~$ python3 puzzle.py
18.291343925000092
chromeos@penguin:~$ python3 puzzle.py

I would suggest keyhunt or some other program.
The code I posted was a creative example using the python bitcoin module.

No, no WIF key is generated with a checksum, the correction (checksum) of the key only takes place after the 2nd conversion.. so the output is then correct.. 6 letters from the Wif-key are random, the last 10 letters from this key are range search.

Abstract:

Code:

L = []
while True:
    for i in range(0x22000000000000000, 0x3ffffffffffffffff, 0x34fde3761da26c):
        b = str(ice.btc_pvk_to_wif(i, True)[:-16])
        x = ''.join(random.choices('123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz', k=6))
        key_WIF01 = b + x + '1111111111'
        key_hex = ice.btc_wif_to_pvk_hex(key_WIF01)
        L.append(key_hex)
        if len(L) == ..............

So how secure are satoshi's coins which were mined directly and put in a public address instead of a BTC address.

Because you are saying that reusing addresses is not good because its not as secure but if this was the case why wouldn't this person who is solving all these puzzles for less than <1 BTC instead try and crack Satoshi's early coins which are sitting in all those public key addresses?

I think why its faster is because the search space is much small compared to the entire 128 bit search space, so its still safe to re-use addresses since as far as we know ECDSA hasn't been cracked yet or some exploit found.

Few people deal with this issue, as soon as it is put on stream then This  standard ECDSA will quickly split.

because I don’t know how, but I’m responsible for about  3 puzzles I have not received any Of the funds because I don’t know how to do it

Hi guys,

In continuation to this thread: https://bitcointalk.org/index.php?topic=1305887.0

While playing around with my bot, I found out this mysterious transaction:

https://blockchain.info/tx/08389f34c98c606322740c0be6a7125d9860bb8d5cb182c02f98461e5fa6cd15

those 32.896 BTC were sent to multiple addresses, all the private keys of those addresses seem to be generated by some kind of formula.

For example:

Address 2:

1ErZWg5cFCe4Vw5BzgfzB74VNLaXEiEkhk
Biginteger PVK value: 10544
Hex PVK value: 2930

and so on...

until the addresses 50 (1MEzite4ReNuWaL5Ds17ePKt2dCxWEofwk) it was already cracked by someone.

Any ideas what's the formula behind the generation of these addresses?

Address 2, pvk decimal value: 3
Address 3, pvk decimal value: 7
Address 4, pvk decimal value: 8
Address 5, pvk decimal value: 21
Address 6, pvk decimal value: 49
Address 7, pvk decimal value: 76
Address 8, pvk decimal value: 224
Address 9, pvk decimal value: 467
Address 10, pvk decimal value: 514
Address 11, pvk decimal value: 1155
Address 12, pvk decimal value: 2683
Address 13, pvk decimal value: 5216
Address 14, pvk decimal value: 10544
Address 15 and after, pvk decimal value: ?

The prize would be ~32 BTC

Well, thanks for the link. However I am not interested in pool bruteforcing because I don't like the idea to possibly receive nothing although invested hard work into finding the correct key (range). The idea is good but the software/pool used therefore is something centralized and I consider it as bad. Sorry, just my 2 satoshis. However, thanks for the link
