Bitcoin's hash rate hit an all time high 500 exahashes/s this month.

To highlight the enormity of this number:

- For every star in our galaxy, the Bitcoin network is calculating 5 billion computations per second.

- It would take ~2000 years for the entire global population, each performing one hash/second, to match the Bitcoin network's hash rate.

- The Bitcoin network performs ~67 times more hashes per second than there are grains of sand on Earth.

- By number of raw operations/second, Bitcoin is ~500x more performant than the world's most powerful supercomputer.

Yet, there are skeptics out there that still believe "bitcoin is backed by nothing".
