Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it

7 Gkeys/s on a 4090, I guess that means only around 1000 GPUs would have been required.

I have only ~ 3Gkeys on Vanbitcracken + 4090, how 7?
Bitcrack is very old and i have only ~500-600 mkeys

Those are generic tools.

An optimized CUDA kernel that targets some specific hash can do well above 7 Gkeys/s on a 4090
