Hi all,

I've recently open-sourced a project called FastscanGPU – a tool that I've been using to explore GPU performance for cryptographic key scanning. It's not a commercial product, just a personal project I thought might be useful to others working in this area.

It currently supports scanning for Puzzle #71 and a multi-million address .bin database, and leverages batch inversion for speed.

If you're interested, you can find the code and some performance stats here: https://github.com/ethicbrudhack/FastscanGPU-BitcoinPuzzleChallengeBreaker-

Happy to answer any technical questions or discuss the implementation details.
