tried but not fruitful , most similar to fastecdsa speed, only gpu based speed will increase,
That's not surprising since fastecdsa call C code to perform heavy computation.
and all gpu developers are just copy paste each other source code for just increament from privatekeys to addresses/hash160, maybe they dont have time to build as per different calc based, above is very simple basic of point add/sub/mul by intg or pubkey(point), let see which one developer jump with creative mind
It's advantage of open source though, developer could use existing code rather than writing from scratch. Besides, without more funding or higher Bitcoin popularity, it could take really long time before someone decide to write such tool.
