One of the great things about Dogecoin is that no one person or group of companies can independently own the Dogecoin blockchain network: it is completely open source, permissionless, decentralized, and peer-to-peer.
The Dogecoin network is controlled by a network of running nodes. Anyone can run a node. Some nodes also mine Dogecoin, and they use computing power to confirm the transactions to be recorded in the next block and the next block. They get block rewards for this.
Dogecoin nodes prevent malicious actors from gaining control of the Dogecoin network through a decentralized consensus mechanism. Simply put, only when more than half of the nodes on the Dogecoin blockchain agree that a transaction is valid will the transaction be processed and recorded in the blockchain.
This decentralized node, peer-to-peer approach ensures the security of Dogecoin transactions without the need for a central controller like a bank to achieve security.
