Very cool! Fun fact, this is basically a simplified version of bitcoin mining.

In order to mine a reward of 3 bitcoin, you just need to find a sha-256 hash that is lower than 2.7×10⁶⁷

The world currently calculates around 780 bitcoin exahashes/s, so one of these $300k hashes is found about every 10 minutes on average.
