I'm not sure what you mean by who can find out they have a collision...the program lets you know when a collision has occurred and the key has been solved.
I mean, How to know ECDSA has collisions like that?
know from any report/research? or who find out
just would like to know step by step develop on this forum before Pollard's kangaroo ECDLP release
the first version is that python script right and then develop c++ for use GPU with high speed calculate
Ummmm the theory has been around since the 1970s; some smart people were just able to program it into a modern day programming language to speed it up/incorporate the use of GPUs.
