If we find 10 same characters of address, Is it possible to find pvk?

For example, we know pvk and address and address is same first 10 characters, how to possible right pvk from this?

Addresses and private keys are not directly related, even if you find 34 characters out of 35 characters you can't find the private key! Happy hunting.😉

Whoopse!

I've found some similiar wallets and hope it will helps others!

I have about half a million addresses that start with the first 8 characters. It's best if someone tries to look into the glass ball and tell me exactly what range to aim for.

@nomachine if you can share with ppls, it would be great!

I don't know what I didn't do. I tried everything possible. There is no pattern here. I even targeted the last eight characters at the end of WIF for seven whole months trying to reconstruct the private key. Whichever option you choose and you don't know the public key, this is unsolvable. Or it can be solved in a couple of thousand years. The numbers in question are the size of the entire universe. Quantum computing is needed to solve this. And a very good one at that.

Those are useless

Determined are the adversaries, toiling with 512 GPUs akin to the heralded 3090. To unravel a 130-bit key, these diligent souls expend near a solar cycle, traversing through 306 days of unyielding pursuit. But even with such a multitude of computational might, the 130-bit realm does not relent easily. A mighty task to conquer the 2^130-bit range beckons for 512 valiant GPUs donning the attire of the 3090. Their efforts encompass days and nights, amid soaring costs, for the serenity of cryptographic victory.The pursuit of knowledge and foresight, the wily Pollard's kangaroo method seeks to challenge Bitcoin's cryptographic prowess.

near a solar cycle, traversing through 306 days of unyielding pursuit

Why 306 days though? Is that how accurate your calculations are, 512 GPUs and 306 days of a solar cycle?

Nice poem!😉

Speaking of patterns...I use this method to see if I can spot anything.

        hex_value = "%064x" % int(decimal_num)
        wif_compressed = ice.btc_pvk_to_wif(hex_value)

        print(f"Part {i + 1} Start point dec:", decimal_num)

But nothing. Just a glass ball, pure luck or brute force...

[rosengold]

Actually I'm using my own tool to search for #66:

https://bitcointalk.org/index.php?topic=5461284.new#new

[nomachine]

I use poor man's  ideas. One of them....

First, i generate list of 500.000 (more is better) WIFs in equal parts  of range....
All WIFs are with first 42 caracters.....

Code:

Import secp256k1 as ice

num_parts = int(input("Enter the number of equal parts you want: "))

def calculate_puzzle66_parts():
    start = 39199331156632797184
    end = 73786976294838206464
    step = (end - start) / num_parts

    wifs = []

    for i in range(num_parts):
        decimal_num = start + (i + 1) * step
        int_num = int(decimal_num)
        hex_value = "%064x" % int_num
        wif_compressed = ice.btc_pvk_to_wif(hex_value)
        wifs.append(wif_compressed[:42])
        print(wif_compressed[:42])

    with open("Puzzle66Wifs.txt", "w") as file:
        for wif in wifs:
            file.write(wif + "\n")

if __name__ == "__main__":
    calculate_puzzle66_parts()

Then I try to solve them like this

Code:

#!/bin/bash

# Initialize the attempt counter
attempts=0

tail -n +1 Puzzle66Wifs.txt | while read -r wif; do
    # Increment the attempt counter
    ((attempts++))

    # Create or overwrite 66.conf with END and the current WIF
    echo "END" > 66.conf
    echo "$wif" >> 66.conf
    echo "13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so" >> 66.conf
    java -jar wifSolver.jar 66.conf

    # Display the number of attempts after each try
    echo "Attempts so far: $attempts"

    # Check if any file with the desired pattern was found and break the loop if it was
    if [ -n "$(find . -maxdepth 1 -type f -name 'END_result_*.txt' -print -quit)" ]; then
        echo "WIF found! Stopping the loop."
        break
    fi
done

echo "Total attempts: $attempts"

It's been going on for months...

May I ask why you guys are doing this? What do you think is the advantage?

When we look at the differences, we can observe that they are roughly consistent, hovering around 0.4 to 0.6.  

The differences appear to fluctuate without any apparent pattern.

As the list unfolds, it weaves a tapestry of interwoven imagination, leaving the observer intrigued by the enigmatic beauty that emerges from the simple elegance of logarithmic transformations.

Like the cryptic genius behind an encrypted message, the origins and intentions of this sequence remain shrouded in mystery, inviting wonder and sparking curiosity within those who seek to comprehend its enigmatic essence.

Whoopse!

I've found some similiar wallets and hope it will helps others!

I have about half a million addresses that start with the first 8 characters. It's best if someone tries to look into the glass ball and tell me exactly what range to aim for.

please share it to me lapeci2017@ g mail . com.

I don't know what I haven't tried because there are so many attempts. I don't remember everything. Years have passed in this.
I started dreaming at night about WIFs ending so....

This  script calculates the common prefixes of the first 42 characters among Bitcoin private keys in a specified range.
It then lists the private keys and prints the top 10 most similar common prefixes in reverse order (longest to shortest).
start = 67079069358943824031
end =  69594534459904217431
Start and end sets the range of private keys (start and end values) and the number of parts to divide the range into (num_parts = 9).
You can adjust these values as you see fit.
