i have a simple alghoritm with cpu in python , you can test it

Code:

import bitcoin
import ecdsa

def private_key_to_public_key(private_key):
   sk = ecdsa.SigningKey.from_string(bytes.fromhex(private_key), curve=ecdsa.SECP256k1)
   vk = sk.get_verifying_key()
   compressed_public_key = vk.to_string("compressed").hex()
   return compressed_public_key

   bitcoin_address = bitcoin.pubtoaddr(public_key)

Why use Bitcoin and ECDSA imports? They're so slow, it feels like a waste of time.

Instead, utilize ICE (import secp256k1 as ice) for this function and the Bitcoin address line:

def private_key_to_public_key(private_key):
priv_int = int(private_key, 16)
return ice.scalar_multiplication(priv_int)

and

bitcoin_address = ice.pubkey_to_address(0, True, public_key)

It's approximately 10 times faster than ECDSA. But even that is miserable if you attack the dinosaur numbers.

The more you delve into Python, the more apparent it becomes that searching for Puzzle 66 through it is pointless.

Perhaps someone knowingly obscures things by selling Python scripts as the ultimate solution. Grin

In fact, what I meant by this comment was the problem of Key Hunt and I wrote different versions of these programs. And compared to Key Hunt, I put this code so that you can test and see the speed of a simple program with a CPUs and a powerful program with GPU that does not work properly.

In general, I am very happy that you paid attention to this code and took your time, and I thank you. And also ice's idea was very good Wink
