Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
There is a script here with hashing very similar to cpuminer. I have achieved results up to 2× faster than VanitySearch or KeyHunt using _mm256 and AVX on the latest AMD processors. However, it is still slow—on the order of several thousand years

I bet that Frozen guy and NoMachine hiding something else. There must be something faster.

Computing the public keys from private keys is magnitudes of order slower than the hashing part. So it doesn't matter if hashing is optimized since the pipeline gets stuck at EC point-scalar multiplication. Hashing will just stay at the base speed of EC computation.
