A Node System refers to a network of connected computers, known as nodes, that collectively support a blockchain. Each node maintains a copy of the entire blockchain and validates transactions.Nodes can be categorized into different types. Full nodes store the complete blockchain and enforce network rules. They play a crucial role in ensuring the integrity and security of the network. Light nodes, on the other hand, only download part of the blockchain and rely on full nodes for transaction verification.The functioning of nodes enhances decentralization, as they operate independently and can join or leave the network freely. This reduces the risk of data manipulation and increases transparency.Nodes also communicate with each other to share information about transactions and blocks. This peer-to-peer communication helps maintain the blockchain’s accuracy and speed. In summary, the Node System is vital for ensuring that blockchain networks function smoothly, securely, and efficiently.
