A full node refers to a node that stores the complete blockchain data, responsible for verifying each transaction to ensure the legality and accuracy of all data. Light nodes only store transaction data related to  themselves, hence their operation and maintenance costs are relatively low since they only focus on partial data. Mining nodes are dedicated to the mining process in blockchain networks, generating new blocks by solving mathematical problems. Super nodes are nodes with higher performance and resources, playing important roles in blockchain networks, such as verifying transactions and maintaining network security."}]}],"pr":"9a9311f91a32e87b1d96649a0ad5538803847558f5ecddfe67f3701bc40867e5"}
