I see, so it was indeed after the solved puzzle!

BTW I found this neighbor Address via keys dot lol - WIF Search for 67's wif on its home page. Two addresses were indicated in yellow on that webpage!
Just looking to optimize my code for random pk search for Puzzle 68, any suggestions or comments greatly appreciated

Or any suggestions on how to make this run from my graphics card please? (Using Ubuntu at moment)
First, for this I have a local
secp256k1 module in a folder on same level as this py file pasted below:
https://github.com/iceland2k14/secp256k1from pathlib import Path
import sys
path_root = Path(__file__).parents[2]
sys.path.append(str(path_root))
import btc.mymodules.mySECP256k1.secp256k1 as ice
import random
targetH160_68 = "e0b8a2baee1b77fc703455f39d51477451fc8cfc"
# 80000000000000000:fffffffffffffffff # 17 digits each
global_count = 0
def random_256():
return "".join([random.choice("0123456789abcdef") for _ in range(16)])
while True:
hex_256_16 = random_256()
for i in ["8", "9", "a", "b", "c", "d", "e", "f"]:
global_count += 1
hex_256 = str(i) + str(hex_256_16)
dec = int(hex_256, 16)
h160_c = ice.privatekey_to_h160(0, True, dec).hex()
if global_count % 100000 == 0:
print(
f"\r",
f"{int(global_count):,}",
f"{str(hex_256)}",
end=" ",
)
if h160_c == targetH160_68:
with open("./found.txt", "a") as file:
file.write(
"Dec: "
+ str(dec)
+ " HexPK: "
+ str(hex_256)
+ " H160_c: "
+ str(h160_c)
+ "\n"
)
print("found!!")
