Man get outta here. Precomputed keys in a database is not the same as vanbitcracken.
No binary, no sourcecode how can we tell the difference? How do we know that vanbitcracken doesn't use a sql database?
Haha...if vanbitcracken were using a database then yes, it is truly slow! I gave reasons not to release binary. But you can say what you want, it's a legit program using the code of VanitySearch. Regardless, if you believe me or not, when I ran the original bitcrack program (which is opensource and what your mod is based off of) there was no gain in TIME that it took to find the keys. Like I said earlier, post all the outrageous MKey/s you want to, I'm all about the TIME, because I do not know what's in your code. You could merely be buffering and padding MKey/s which will not increase the actual TIME it takes to find a key...
Vanbitcracken uses/generates random points through a range. I said this long ago...in smaller ranges (up to around 44 bits), random is faster, in my tests. It uses the power of the rekey function to dictate how often random points are regenerated. So it can either generate/spread out random points and sequentially start from each random point or regenerate random points every x seconds/keys. AND, it can utilize multiple GPUs!
Bottom line, vanbitcracken using one GTX 1060 card, kicked your GTX 1070Ti and sp mod's a$$...period.
