144M private keys are a drop in the ocean of keys. What's the point of generating public keys from private keys (it takes a long time). You need to add and multiply and divide public keys (XY coordinates). The process can of course be speeded up if you use C++. Not a single Python script has yet found complex solutions to a puzzle.
You have some unique creative designs from Jean Luc Pons, this is the highest level of programming skill and experience. Everything else can only be modified, new algorithms and new functions can be added to the C++ code. Look in the wrong direction... It's better to find the correct divisor for the unknown private key. Correct - this means the remainder of the division is zero!!! This is a good task, then there will be a result.
144 million keys using python script? Yeah it will take a few hours, at least for me.
I'm not sure about the highest programming skills since kangaroo is outdated, and in practice useless for large keys/ranges.
Also there is a script in python which divides a point by a start/end range, it's really useful to find the divisor, I have both scalar version and point version posted on project development board, there is also a version which operates with 2 targets and divides them by the set range, and on top of that there is a subtraction function to sub the results of division, I suggest you play around with scalar version and change the range, also change the last digit of your targets to at least have 10 keys ending with 0 through 9 and then repeat divide ranges with all of them.
Start by subtracting 2^129 from a known k in puzzle 130 range and then use fake #130 as first, and the result of subtraction as second target, start your range from 2, 32 and keep increasing it the next time, 32, 256, then 256, 2048 and so on, try to check the index number, if you see your scalar divided by 48 results in an integer, then that's your divisor. Set multiples of 48 as start, end range and solve the key.
I'm working on a method to determine with 100% accuracy whether a point divided by a number results in an integer or not. Stay tuned.😉
It is difficult to specify which result is integer or not because they are all within the same curve, and can be represented by several pk.
