Nodes

In the context of blockchain, nodes are computers or devices that participate in the network and ensure its operation. Nodes can be classified into different types:

1. Full Nodes: These nodes store the complete history of blocks and verify all transactions. They ensure decentralization, as anyone can become a full node and support the network.
2. Light Nodes: These nodes store only a portion of the data, allowing them to operate faster and use fewer resources. They rely on full nodes for information verification.
3. Mining Nodes: These nodes perform complex computations to create new blocks and maintain the security of the network.

Nodes play a crucial role in maintaining the integrity and security of the blockchain, enabling user interaction without the need for intermediaries. Thanks to the decentralized structure of nodes, blockchain becomes less vulnerable to attacks and manipulation.
