Also for checkpoint.txt I just need to paste x coordinates on one line per key and save their private keys? What else do I need to change on the script?
I appreciate it.
Edit, I got it running, I just need to know what to change for addition and subtraction, should I put values in decimal? And why it won't show anything on screen? Lol it just blinks endlessly.
Here is how to tune script as per your needs:
1. xy.txt file must have x and y coordinates in decimal format with a single space between them, as I clarified earlier.
2. In checkpoints.txt file you don't need to save their private keys, why? that is whole point, because we keep starting 100 million or 1 billion pub keys' x coordinates which will work as 2 billions, so it is obvious that their private keys are from 2 to 1 billion or the last 1 billion.
3. There are 3 things that you can change, step size to be subtracted, number of steps, and number of iterations.
all these are in numbers not in points.
4. Finally, why script was blinking, is because it was loading checkpoints.txt file, In my case I had 8 GB RAM with around 5.5 GB checkpoints.txt file, on a dual core system. It was taking around half an hour before printing steps.... Be patient, if no error occur, it will start printing within half an hour.
I understand it until this far and I already fulfilled the first requirements for the xy.txt with my target public key in decimal with a space between the x and y coordinates but I need to ask a question concerning the checkpoints as this is where I am currently stuck. New to the ECC curve but drastically learning as the day goes by... what I need to know is, how to get the checkpoints for the puzzle 130 and how many checkpoints do i need their x coordinates in the checkpoints? Also will the code print the target public key's equivalent private key or will it save it to a file? Thanks as we all learning...
