Dogecoin is an open-source digital currency created by Billy Markus and Jackson Palmer as a "Joke-Curre cy" and was forked from Litecoin in December 2013.
Dogecoin differs from Bitcoin protocol in several ways, one of which is by using Scrypt technology.

Dogecoin can be mined individually, or by joining a mining pool
