Nodes are essential for maintaining the integrity and security of the blockchain network as they confirm transactions and create new blocks.","a":"In a blockchain network, a node refers to a computer connected to the blockchain network, which  can be personal devices (such as mobile phones, mining machines, etc.), servers, or other types of computers. Nodes are responsible for processing information transmission, validating transactions, and maintaining the consistency of blockchain data in the network. They collectively form the infrastructure of the blockchain distributed database system and achieve the decentralized feature. In a blockchain network, nodes exchange data through a peer-to-peer communication method and reach consensus through a consensus algorithm. According to different coverage, nodes can be divided into full nodes and lightweight nodes. Full nodes possess all transaction data across the entire network, while lightweight nodes only contain transactions related to themselves."}]}],"pr":"e84ed81eb3edf78f2585918833cae16f18255e84421879f96f110e4b9be3d656"}
