A node in blockchain is a computer or device that participates in the network by maintaining a copy of the blockchain and validating transactions. Nodes can be full nodes, which store a complete copy of the blockchain, or light nodes, which only store a portion of the blockchain. Nodes communicate with each other to propagate new transactions and blocks, ensuring that the network remains secure and decentralized.

A node in blockchain technology is a computer that participates in the blockchain network. Nodes are responsible for maintaining a copy of the blockchain ledger, verifying transactions, and broadcasting new blocks to the network.
Nodes can be either full nodes or lightweight nodes. Full nodes maintain a complete copy of the blockchain ledger, while lightweight nodes only maintain a partial copy of the ledger. Lightweight nodes rely on full nodes to verify transactions and broadcast new blocks to the network.
Nodes are connected to each other through a peer-to-peer network. This allows nodes to communicate with each other and share information about the blockchain ledger. Nodes use a consensus mechanism to agree on the state of the blockchain ledger. The consensus mechanism ensures that all nodes have the same copy of the blockchain ledger.
There are many different types of nodes in blockchain networks. Some of the most common types of nodes include:
- Mining nodes: Mining nodes are responsible for verifying transactions and adding new blocks to the blockchain ledger.
- Full nodes: Full nodes maintain a complete copy of the blockchain ledger and verify transactions.
- Lightweight nodes: Lightweight nodes maintain a partial copy of the blockchain ledger and rely on full nodes to verify transactions.
- Archive nodes: Archive nodes maintain a complete history of the blockchain ledger.
- Pruned nodes: Pruned nodes remove old and unnecessary data from the blockchain ledger.
Nodes are essential to the operation of blockchain networks. They provide the infrastructure that allows blockchain networks to function securely and efficiently.
