Created in 2013 by software developers Billy Markus and Jackson Palmer, Dogecoin is a decentralized cryptocurrency initially based on the Shiba Inu dog meme. Despite its humorous origins, Dogecoin has gained a significant following and is known for its fun and friendly community. Like Bitcoin and Litecoin, Dogecoin uses a blockchain to record and verify transactions but distinguishes itself with a fast block time of one minute and low transaction fees. Its mascot, the Shiba Inu dog, and its engaged community contribute to its unique branding. While not as mainstream as some other cryptocurrencies, Dogecoin remains popular for its lighthearted and accessible approach.
