The workload of the operation module is large, and it needs to efficiently handle a large number of transaction requests. In China Mobile Blockchain, transactions in the transaction module are the basic units for executing state transition operations on the blockchain, and either all transactions succeed or all fail. At the same time, the operation module also ensures that all transactions are valid and legitimate to maintain the security and stability of  the blockchain network."}]}],"pr":"2ec8d98fe7a1269765907a9ff39463380eb391651456b1bf5dc2aa4a2970b7f3"}
