Blockchain-based transaction processing method and apparatus

Abstract

A blockchain-based transaction processing method may comprise: in response to a designated account being logged in through an application client, generating, according to input to-be-operated account information and configured operation content, an operation instruction comprising the to-be-operated account information and the operation content; and sending the operation instruction to a node in a blockchain network, causing the node in the blockchain network to invoke a smart contract corresponding to the designated account upon receiving the operation instruction, and to execute an operation according to the operation content on another account corresponding to the to-be-operated account information.

         6 . The system of  claim 5 , wherein the operations further comprise: before executing the unfreezing operation on the second account, determining that the second account is in a frozen state; and wherein executing the unfreezing operation on the second account comprises: in response to determining that the second account is in the frozen state, executing the unfreezing operation on the second account. 
     
     
         7 . The system of  claim 3 , wherein executing the operation on the second account according to the transaction processing logic comprises: in response to the operation content being to suspend an account, executing a suspending operation on the second account according to the transaction processing logic, the suspending operation executed on the second account being used to instruct the second account to stop execution of transactions. 
     
     
         8 . The system of  claim 3 , wherein executing the operation on the second account according to the transaction processing logic, comprises: in response to the operation content being to resume an account, executing a resuming operation on the second account according to the transaction processing logic, the resuming operation executed on the second account being used to instruct the second account to resume execution of transactions. 
     
     
         9 . The system of  claim 8 , wherein the operations further comprise: before executing the resuming operation on the second account, determining whether the second account is in a suspended state; and wherein executing the resuming operation on the second account comprises: in response to determining that the second account is in the suspended state, executing the resuming operation on the second account. 
     
     
         10 . The system of  claim 3 , wherein executing the operation on the second account according to the transaction processing logic, comprises: in response to the operation content being to close an account, executing a closing operation on the second account according to the transaction processing logic, the closing operation executed on the second account being used to instruct to stop execution of transactions. 
     
     
         11 . The system of  claim 3 , wherein executing the operation on the second account according to the transaction processing logic comprises: in response to the operation content being to open an account, executing an opening operation on the second account according to the transaction processing logic.
