Nodes in the Dogecoin blockchain, much like in other blockchain networks, play a pivotal role in maintaining the network's integrity and decentralization.
Here's an explanation of how nodes work in the Dogecoin blockchain, with support from reputable sources:
Types of Nodes:
Full Nodes:
These are complete copies of the Dogecoin blockchain. They store and validate every transaction from the genesis block to the latest one.

Lightweight (SPV) Nodes:
Lightweight nodes, also known as Simple Payment Verification (SPV) nodes, do not download the entire blockchain. They only download block headers and a small amount of additional information to verify transactions.

Validation of Transactions:
Full nodes validate transactions by checking them against the consensus rules of the Dogecoin network. This ensures that transactions are legitimate and adhere to protocol rules.
Consensus Enforcement:
Nodes enforce the consensus rules of the network, ensuring that all participants agree on the state of the blockchain. This is vital for preventing fraud and maintaining network integrity.

Relaying Transactions:
Full nodes relay transactions to other nodes in the network. This is how transactions propagate throughout the network.

Broadcasting Blocks:
When a miner successfully mines a new block, they broadcast it to the network. Full nodes receive, verify, and add this block to their local copy of the blockchain.
Network Security:
A higher number of nodes increases network security, making it more difficult for any single entity to control the network.

Resilience:
Nodes contribute to the network's robustness. If some nodes go offline due to technical issues or attacks, the network can continue to operate as long as there are enough functioning nodes.

Wallet Functionality:
Wallet software can function as lightweight nodes, allowing users to manage their addresses, view balances, and create transactions without the need to run a full node.
In summary, nodes are the backbone of the Dogecoin blockchain, ensuring transaction validation, consensus enforcement, and network security. They contribute to the decentralization and reliability of the network, allowing Dogecoin to operate as intended.
