Dogecoin uses a blockchain, which is a shared ledger of transactions. A transaction moves DOGE from one address to another, then miners collect valid transactions into blocks. Once the network accepts a block, the transactions inside it become part of Dogecoin’s transaction history.
Mining is the process that secures that ledger. The network uses a simplified version of the Scrypt key derivation function as proof of work, targets one-minute blocks, and adjusts difficulty after every block. Starting at block 600,000, the reward became a permanent 10,000 DOGE per block.
Dogecoin is also connected to Litecoin through merged mining, often called AuxPoW, or auxiliary proof of work. In practice, miners can use Scrypt mining work in a way that helps secure more than one compatible chain. Merged mining with Dogecoin began on Sep. 11, 2014, and Dogecoin’s current source tree still includes AuxPoW code paths for merge-mined blocks.
For everyday users, this means Dogecoin is not mined by ordinary laptops in any meaningful way. Users normally interact with DOGE through exchanges, wallets, payment tools, and on-chain transfers. Running a node is still possible through Dogecoin Core, which lets anyone operate a node while using Scrypt proof of work.
Dogecoin Core remains the reference software for the network. Dogecoin Core 1.14.9 is the current release, published on Dec. 1, 2024, with bug fixes inherited from upstream Bitcoin and Namecoin code. That does not make Dogecoin a fast-moving smart-contract platform. It does show that the core client is still maintained.
