Dogecoin (DOGE), born on December 8, 2013, is based on the Scrypt algorithm and originated as a fork of the Litecoin codebase. DOGE's founder, Jackson Palmer, initially intended to create a "fun" digital currency, and it became known for its iconic Shiba Inu dog face meme. As people became widely familiar with the meme, Dogecoin garnered significant interest in the world of digital currencies, leading to a rapid increase in its price.

Dogecoin (DOGE) uses a Proof of Work (PoW) mechanism, similar to Bitcoin, where miners add new blocks to the distributed ledger for validation. However, unlike the Bitcoin network, Dogecoin employs the Scrypt hash algorithm from Litecoin, which allows miners to process and record transactions more quickly and with greater efficiency. In the Dogecoin network, a block confirmation time is just 1 minute, significantly faster than Bitcoin's 10 minutes. Furthermore, Dogecoin utilizes a merged mining model, enabling Litecoin miners to simultaneously mine Dogecoin, providing miners with increased flexibility.

Dogecoin is widely used for tipping systems on platforms like Reddit and Twitter, as a way to reward users who create or share high-quality content. It has been adopted by online merchants and is also used for peer-to-peer transactions among consumers.
