@nomachine - for another puzzle, do I need to change anything in the script other than keyrange and pubkey? Why am I asking you? Because, in order to test, I put the public key from #64 and a very small keyrange, between f7051f26b09112d4 and f7051f2ab09112d4 (17799667353283269332:17799667370463138516) and it is obvious that the search is done outside the keyrange, in decimal, from 10000000000000000000 to 29999999999999999999 or even greater.




Pindex is essentially an identifier for the points being processed and helps keep track of the progress of the search and identify points that could potentially solve the cryptographic puzzle. It's used to match points from different sets and determine if they share the same x-coordinate. Since these values are generated randomly, they may not always fall within the specified range, especially if the random number generation is not constrained.
The script employs a kangaroo twins hopping strategy to search for solutions. The hopping strategy involves adding a certain value to the x-coordinate of a point and then computing the next point in the sequence. Depending on the hopping value, it is possible for the point to move outside the defined range.
