Paper wallets are simply Bitcoin private keys printed on a piece of paper. It can also have the Bitcoin public address printed on it, but not necessarily. Paper wallets are an effective way of storing Bitcoin private keys offline. This page contains sample addresses and/or private keys.

Essentially, if the average block time is trending faster than 10 minutes, difficulty is increased.
