I have a script that’s searching for the private key of puzzles 66,67, and 68. Just by just by searching through the hex range 20000000000000000 - 2ffffffffffffffff
Same can be done with the rest of the addresses. I only have to search through 1 range, but I can search for 4 addresses all at once.
So puzzle 68 may be cracked before 66 🤷‍♂️
If anyone is interested let me know. I will definitely need more computer power. But it’s worth it.. I’ve already tested it with previous addresses. Works like a charm. https://ibb.co/jzZTHhV
