A prototype in work. Solves an 84 bit range search in under 1 minute, but cannot solve 85 bits for some reason! More work tomorrow. It is something in the GPU...more troubleshooting!
It does not work above 84 bit range. It is not for sale nor available to test. If I ever get it to work right, will use in the pool for the larger challenges with x points exposed.
CPU walks the baby steps with DP method (with limit setting). GPU burns through the range with giant steps, looking for collisions.
Try my pubkeys....
