I don't understand what "difficulty" means and how it really relates to "target".
I understand what "target" is - it tells the miners, how small the resulting hash should be. (Basically, how many zeroes are there at the beginning, altough not exactly.)
But I don't understand what "difficulty" is, how it relates to the target and why it's important. I tried to read the article on wiki - https://en.bitcoin.it/wiki/Difficulty - but I don't have a clue what is it trying to say either.
