Dogecoin operates on its own independent blockchain, distinct from Bitcoin and Ethereum. Launched in 2013, Dogecoin's blockchain was developed using open-source code from Litecoin, enabling fast transaction confirmations and decentralized mining. The network employs the Scrypt algorithm and a proof-of-work consensus mechanism, facilitating quick and low-cost transactions. Unlike Bitcoin, Dogecoin has no supply cap, allowing for an unlimited supply of DOGE. It is not built on Ethereum or its ERC-20 standard. The Dogecoin network is maintained by a decentralized group of miners and nodes, ensuring no central authority controls it.
