I have done a few work trying to speed up present realization of secp256k1 via GPU and have no idea how to do it.
I'm not even considering secp256k1 warpseeding through the GPU—just SHA-256 and Base58

Wait, are you actually just processing WIFs using a bunch of GPUs?

Yep, I've been writing about it for the last five pages, if you haven't noticed. And let me tell you a secret: only WIFs starting with "5HpHagT65TZzG1PH3CSu63k8DbpvD8s5i".
