A successfully hashed #Bitcoin block (orange dot) is one that is lower than (to the right of) the target hash (white line). A smaller target hash, one with more leading zeros, results in a smaller subset of valid hashes, which makes it more difficult to successfully hash blocks.

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".
