and 201, receiving a call request, and calling a program in the intelligent contract according to the call request.
The intelligent contract calling method based on the blockchain is applied to intelligent contract calling equipment based on the blockchain, namely node equipment, the type of the intelligent contract calling equipment based on the blockchain is not particularly limited, for example, the intelligent contract calling equipment based on the blockchain can be a terminal or a server, and the terminal is taken as an example in the embodiment.
The terminal receives a calling instruction of the intelligent contract, wherein the calling instruction can be actively triggered by a user, for example, the user clicks a button of 'xxx calling' on a display interface of the terminal, and the calling instruction of the intelligent contract is actively triggered; in addition, the call instruction may be automatically triggered by the terminal, for example, a trigger condition of the call instruction preset in the terminal is: automatically triggering every morning; when the terminal detects that each day is early morning, the terminal automatically triggers the calling instruction of the intelligent contract.
And the terminal receives the calling instruction of the intelligent contract, and the terminal calls the intelligent contract according to the calling method so as to record data by calling the intelligent contract.
And 202, counting the execution steps of the program in the intelligent contract when the intelligent contract is called, and if the counted execution steps reach a preset upper operation limit, executing on-site saving operation to obtain transaction record related information.
When a terminal counts and calls an intelligent contract, counting execution steps of programs in the intelligent contract (the programs in the intelligent contract can be understood as logic codes or coding methods) during the intelligent contract call, if the counted execution steps reach a preset upper operation limit (the preset upper operation limit refers to the upper operation limit of the programs in the intelligent contract, which is preset, the preset upper operation limit can be set according to specific scene setting, terminal performance and the like, for example, the preset upper operation limit can be 100), executing on-site saving operation on the intelligent contract by the terminal, and acquiring on-site saving operation saved intelligent contract execution related information by the terminal, namely, saving the intelligent contract execution related information as transaction record related information by the terminal; specifically, the method comprises the following steps:
(1) Counting the execution steps of programs in the intelligent contracts when the intelligent contracts are called, and if the counted execution steps reach a preset upper operation limit, executing on-site saving operation to record program execution positions and program variable information in the intelligent contracts;
(2) And sorting the program execution position and the program variable information to generate transaction record related information.
The terminal counts the execution steps of the program in the intelligent contract (or the execution steps of the intelligent contract method) when the intelligent contract is called, and if the execution steps reach the preset operation upper limit, the terminal executes the on-site saving operation so as to record the program execution position and the program variable information in the intelligent contract; the terminal sorts the program execution position and the program variable information to generate transaction record related information, in this embodiment, when the terminal invokes the execution step of the program in the intelligent contract to the upper limit of the operation, the terminal performs on-site save operation on the intelligent contract to lock the intelligent contract, so as to facilitate the subsequent restoration of the intelligent contract according to the saved transaction record related information, and the execution of the call is continued, specifically:
And 203, restoring the execution environment of the intelligent contract according to the transaction record related information so as to continuously call the program in the intelligent contract.
The terminal restores the execution environment of the intelligent contract according to the transaction record related information, namely, the terminal carries out zero-restoring operation on the execution steps of the program in the intelligent contract so as to facilitate the terminal to continuously call the intelligent contract; specifically, the method comprises the following steps:
(1) The state of the intelligent contract is adjusted to be a field storage state, and the execution environment of the intelligent contract is restored according to the program execution position and the program variable information corresponding to the transaction record related information;
(2) Restoring the state of the intelligent contract, and zeroing the execution step of the intelligent contract to continuously call the program in the intelligent contract.
The terminal adjusts the state of the intelligent contract to be a field storage state so as to prevent other people from calling the intelligent contract, so that the calling is wrong at this time, and further, the terminal restores the execution environment of the intelligent contract according to the program execution position and the program variable information corresponding to the transaction record related information; after the execution of the intelligent contract execution environment is completed, the terminal restores the state of the intelligent contract, so that the intelligent contract is in an offsite storage state, and the terminal returns the execution steps of the intelligent contract to zero so as to continuously call the intelligent contract.
204, Upon detecting that the program in the smart contract is called, generating a transaction to save the calling result of the smart contract.
When the terminal detects that the intelligent contract is completed, the terminal acquires the calling result of the intelligent contract and sorts the calling result to generate a transaction.
In the embodiment of the application, a terminal receives a calling request and calls a program in an intelligent contract according to the calling request; counting the execution steps of programs in the intelligent contracts when the intelligent contracts are called, and if the counted execution steps reach a preset upper operation limit, executing on-site storage operation to obtain transaction record related information; restoring the execution environment of the intelligent contract according to the transaction record related information so as to continuously call the program in the intelligent contract; generating a transaction to save the calling result of the intelligent contract when the program in the intelligent contract is detected to be called; according to the technical scheme, when the execution step of calling the intelligent contract reaches the preset upper operation limit, the intelligent contract is subjected to field preservation operation, so that the intelligent contract is locked, the execution step of a program in the intelligent contract is zeroed, the execution environment of the intelligent contract is restored, and then the program in the intelligent contract is continuously executed, so that the calling exceeding the limit of the execution step is automatically operated, and the calling operation of the intelligent contract is more convenient; in addition, the method ensures that the single execution step of the intelligent contract is not limited, and further reduces the development difficulty of intelligent contract logic.

301, receiving a call request, and determining an intelligent contract corresponding to the call request.
302, Acquiring the state of the intelligent contract, and determining whether a program in the intelligent contract can be called according to the state of the intelligent contract.
The terminal receives the call request, determines an intelligent contract corresponding to the call request, acquires the state of the intelligent contract, and determines whether the intelligent contract can be called or not according to the state of the intelligent contract, and specifically comprises the following steps:
(1) Acquiring the state of the intelligent contract, and judging whether the state of the intelligent contract is a field preservation state or not;
(2) If the state of the intelligent contract is a field preservation state, judging that the program in the intelligent contract can not be called;
(3) And if the state of the intelligent contract is not the field preservation state, judging that the program in the intelligent contract can be called.
That is, the terminal acquires the state of the smart contract, and the terminal judges whether the state of the smart contract is a field save state (the field save state can be understood as a lock state); if the state of the intelligent contract is a field preservation state, the terminal judges that the program in the intelligent contract can not be called; if the state of the intelligent contract is not the field preservation state, the terminal judges that the program in the intelligent contract can be called.
303, If the program in the intelligent contract can not be called, outputting a call failure prompt.
304, If the program in the intelligent contract can be called, calling the program in the intelligent contract according to the calling request.
If the program in the intelligent contract can not be called, the terminal outputs a call failure prompt, and the intelligent contract call of the terminal is ended; if the program in the intelligent contract can be called, the terminal calls the intelligent contract according to the call request.
In this embodiment, when receiving a call request of an intelligent contract, the terminal determines whether the intelligent contract can be called according to the state of the intelligent contract, if the intelligent contract is in a field storage state, that is, it can be determined that other users are calling the intelligent contract, and the terminal determines that the intelligent contract cannot be called at the moment; if the intelligent contract is not in the field preservation state, the terminal calls the intelligent contract according to the call request, so that the intelligent contract is more convenient to call, and meanwhile, the intelligent contract calling error is avoided.
Referring to FIG. 4, FIG. 4 is a flow diagram of one embodiment of a blockchain-based intelligent contract invocation method provided in an embodiment of the application.
In some embodiments of the present application, a blockchain-based intelligent contract invoking method includes steps 401-402:
And 401, counting the total calling duration of calling the intelligent contract.
The terminal counts the calling total duration of the intelligent contract, wherein the calling total duration can be determined by the time triggered by the current time reducing calling instruction, and the calling total duration can be counted in real time; the terminal compares the total calling time length with preset time length (the preset time length refers to the time length of normal execution of the preset intelligent contract) so as to determine whether the intelligent contract is executed normally, if the total calling time length does not exceed the preset time length, the terminal judges that the intelligent contract is called normally, and the terminal calls the intelligent contract; if the total calling duration exceeds the preset duration, the terminal judges that the intelligent contract calling is abnormal.
