DogeCoin (DOGE) started when two developers named Billy Markus and Jackson Palmer created a cryptocurrency inspired by a famous "Shiba Inu" meme. It quickly gains exposure and a community formed around the currency.
The technology behind DogeCoin is similar to Litecoin. They have identical Proof of Work algorithms, and both of them feature transactions that are cheap, instantaneous, and anonymous. The difference is that DogeCoin does not have a token cap, and blocks take approximately 1 minute to mine.
