Originally formed as a joke, Dogecoin was created by IBM software engineer Billy Markus and Adobe software engineer Jackson Palmer. They wanted to create a peer-to-peer digital currency that could reach a broader demographic than Bitcoin. In addition, they wanted to distance it from the controversial history of other coins. Dogecoin was officially launched on December 6, 2013, and within the first 30 days, there were over a million visitors to Dogecoin.com.
On May 9, 2021, SpaceX announced a rideshare mission to the Moon completely funded by Dogecoin, thus becoming the first space mission funded by a cryptocurrency. Elon Musk confirmed this news via Twitter,DOGE-1 will be a minor 40 kg rideshare payload on IM-1 mission in Q1 2022.
