Blockchain data includes block data and state data. Block data describes the records of each transaction occurring on the blockchain, such as transfers and recharges. State data records the current status of each account and smart contract, such as balances. These data are stored and processed by blockchain nodes.↵↵Blockchain nodes are programs that can run on devices such as computers and virtual machines.  Multiple nodes form a complete blockchain network through network connections. In a blockchain network, data is stored in independent distributed databases, such as LevelDB, RocksDB, MySQL, etc. These databases are responsible for storing and processing the transaction data of the blockchain, ensuring the security and reliability of the data."}]}],"pr":"272f2dfedbd57ffe5bdd8fcc12bca2ef698d21f85c0bce592bf5dc040394b089"}
