Full nodes are responsible for validating transactions and storing the complete blockchain data, while lightweight nodes only store transaction data related to themselves. Mining nodes are used for mining new blocks, and supers nodes are a combination of full nodes and lightweight nodes, possessing a certain degree of verification and mining capabilities. These nodes together form the basic infrastructure of the blockchain network, ensuring its decentralization, security, and credibility."}]}],"pr":"af8d76348d707d5b91c16e38291c0071d7efcc696a2a3a7f1e7d11c8a12fc8be"}
