Facts and maths are great, but you never know do you!

That's why I've had my vanitygen running on the satoshi wallets since 2011.

Lol @ vanitygen. I've written a much optimized version. With 30k addresses, it generates AND compares with 33 million keys per second on the CPU. Vanitygen is much slower.

Which for the purpose of this dubious scenario is like the guy with a bucket emptying the ocean laughing at the guy with a teaspoon trying to do the same thing.

Even so, my version is on the CPU and is therefore much efficient than a GPU which uses more watts. The key to this optimization is that I skip the base58 phase and use the RIPEMD160 hash and compare the bytes in a boolean expression. This way I also don't need to use PCRE ot strcmp. On my i5-4670k I do 33 million keys per second(which are compared to the list of 30k addresses) per thread.

The only downside is this method requires a list of keys in a file, they are supplied in base58 format and inside they are decoded back to their RIPEMD160 states.
