(honestly i am very confused by an assumption of discerning a private key by hope for collision, as a normal thing without explanation or reminder of some new change in technology or research making this reasonable. i can't tell what is real here.)
Why confused? What I described in my OP on the GnuPG ML should be possible today or in the future, even if chances are super minimal. I mean what does Bitcoin Collider Software, like LBC, Brainflayer etc. does? The 256bit HEX values people are looking for, as understood, need also be in a valid range, according to Bitcoin specs. An example collision could look like this if you examine this GnuPG signature (which has a secret Bitcoin key with a positive balance: (seen in a Usenet posting) https://lists.gnupg.org/pipermail/gnupg-users/2020-January/063203.html Regarding research (and GnuPG) people could write for example a program which checks a complete publicity available key server dump for signature packets #2 i.e the once that are only 256bit long and then convert them, keep them in a text file and use a balance checker program ...
