Generate Bitcoin Vanity Address
Vanity addresses are valid bitcoin addresses that contain human-readable messages.
For example, 1LoveBPzzD72PUXLzCkYAtGFYmK5vYNR33 is a valid address that contains the letters forming the word "Love" as the first four Base-58 letters. Vanity addresses require generating and testing billions of candidate private keys, until one derives a bitcoin address with the desired pattern...reference
