The Dogecoin blockchain, known as Dogechain, uses a proof-of-work consensus algorithm, meaning that DOGE is mined by solving complex mathematical problems to verify new blocks. Miners typically have dedicated computers for mining Dogecoin — and the more powerful the hardware, the easier it is to mine new Dogechain blocks. There is no limit to the token supply of Dogecoin, so new DOGE can be mined indefinitely.
