thankyou for advice, i make the KNN algorithm work with my previous code but have some trouble with other codes, some confusion call the rest codes to work with scan range, but it's work.
i test on 65 bit.

mightbe push my luck for 66 for couple weeks.

sure, i'll dm you, btw your codes looks cool and more advanced!
wow!, i'm beginner can you teach ?!

#EDIT
from my codes provide chance to find the 66 puzle is on 3000000000000000:37fffffffffffffff , below that it's just give same result hash and different 13zb1 address derived from private key. (but it's just speculation.)

Tepan, you seem hesitant to share your code, but trust me, what you are doing has already been done, in a much faster programming language, C++; CPU and GPU versions, where you can provide a h160 or address prefix and it will find EVERY collision in a 40 bit range, in less than a minute (depending on GPU setup).

Your python script may have some different settings/search criteria, but the bottom line is the same.

People are trying to help you speed up your code, in python, because your code is extremely slow. If your python code isn't checking at least 250,000 keys per second, then it desperately needs an overhaul. I can create a python script to do what yours is doing, that will check at least 250,000 keys per second, python only, single core, in less than 10 minutes.

But hey, you do you.

Zahid888, is the expert at prefix searches...probably has the world's largest prefix database, he can attest to what I am saying to you.

Wow I just did the math to see how long it would really take if you went from start to finish with no stride for puzzle 66
With the start and end params of 20000000000000000...3ffffffffffffffff and a 3080 at 1100 MKeys/s or 1.1 billion keys a second
I got
33,539,534,679 seconds
558,992,244 minutes
9,316,537 hours
388,189 days
1,063 years

Yes, perhaps I have the world's highest number of prefixes for puzzle66.
And maybe I have conducted the most experiments on prefixes worldwide, whether it be in the form of base58 or hash160.
Through these experiments, I have consistently encountered a 50-50 probability of outcomes.
Sometimes, a few bytes of a private key match, and at other times, they do not match at all.
So, there is no difference between a 'private keys with matched prefixes' and a 'totally random private keys'.
I save addresses with prefixes only as a 'proof of work'; beyond that, these addresses serve no further purpose.

If your objective is solely to locate addresses with matching prefixes, it would be advisable to opt for the vanity search implemented by WanderingPhilosopher, which is based on multi-GPU counting, rather than attempting to enhance speed in Python, which never ever compete with GPU-counting.

Edit :

---

Anyway, I have scanned about 6.5% of puzzle 66 keys individually, I need your best wishes, and a lot of good wishes from my side to all of you.

Has anyone ever figured out what the #64 and #120 keys were, up to now?

For educational purposes. Can anyone provide Python code for iterating through private keys in a specified range that works with CUDA? Or a link to such a resource.
Thank you.

It is 20 times faster in Rust  then Python/Numba

But there is a 0 puzzle script written in Rust.
There is this one here as an example

Thank you, colleagues, for suggesting Rust and C  , but for educational purposes, what is specifically required is Python code for CUDA that can brute-force keys.
