Dogecoin (DOGE) is based on the popular "doge" Internet meme and features a Shiba Inu on its logo. The open-source digital currency was created by Billy Markus from Portland, Oregon and Jackson Palmer from Sydney, Australia, and was forked from Litecoin in December 2013. Dogecoin's creators envisaged it as a fun, light-hearted cryptocurrency that would have greater appeal beyond the core Bitcoin audience, since it was based on a dog meme. Tesla CEO Elon Musk posted several tweets on social media that Dogecoin is his favorite coin.
Dogecoin differs from Bitcoin's proof-of-work protocol in several ways, one of which is by using Scrypt technology. The altcoin has also a block time of 1 minute, and the total supply is uncapped, which means that there is no limit to the number of Dogecoin that can be mined.You can mine Dogecoin either solo, or by joining a mining pool. A Doge miner can mine the digital currency on Windows, Mac or Linux, and with a GPU. As of 2014, you can also mine Litecoin in the same process of mining Dogecoin, as the processes were merged.
Dogecoin has been used primarily as a tipping system on Reddit and Twitter to reward the creation or sharing of quality content. You can get tipped Dogecoin by participating in a community that uses the digital currency, or you can get your Dogecoin from a Dogecoin faucet. A Dogecoin faucet is a website that will give you a small amount of Dogecoin for free as an introduction to the currency, so that you can begin interacting in Dogecoin communities.
