Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
Intelligent contract compilation execution of blockchains generally does not have cross-platform extensibility. Since there are processors of different vendors, different brands and different generations, and the instruction sets supported by these different processors are often different and the same vendor is the same brand, but the instruction sets supported by the processors of different generations are not exactly the same, the same program code written in the same high-level language, and the machine code converted by the compiler on different servers may be different. Specifically, in the process of converting program code written in a high-level language into machine code, a compiler optimizes the program in combination with the characteristics of a specific instruction set of a processor to improve the execution speed of the program, and such optimization is often related to specific processor hardware. Thus, the same machine code, one on x86, may not be able to run on ARM, and even the same x86 platform, the instruction set is continuously enriched and expanded over time, which results in different generations of machine code running on the x86 platform. Moreover, because executing machine code requires scheduling by the operating system kernel for the processor, machine code that supports operation under different operating systems may differ even with the same hardware. Therefore, the intelligent contracts in the blockchain are executed, the intelligent contracts are written by a specific language and then pushed to each node of the blockchain to be compiled and executed respectively, so that the intelligent contracts are executed, but the compiling and executing efficiency of the intelligent contracts are different due to the different hardware performances of different machines, the intelligent contracts can greatly influence the nodes with lower part of hardware performances, and the nodes are disconnected when serious, so that the blockchain data processing efficiency is low.
Aiming at the problems, the execution method, the device, the equipment and the storage medium of the blockchain intelligent contract provided by the application realize simpler and more convenient execution and high efficiency of the blockchain intelligent contract. Specifically, for executing intelligent contracts in a blockchain, the intelligent contracts are usually compiled by using a specific language, so that each node in the blockchain compiles and executes the intelligent contracts, and the inventor finds that when the contracts compiled by the specific language are pushed to each node of the blockchain to respectively compiles and execute, the compiling and executing of the intelligent contracts can be greatly influenced due to the hardware difference of each node processor, and even the node is led to be offline in severe cases, so that the processing efficiency of the blockchain data is low, and considers the problems, the inventor researches whether the compiling and executing of the intelligent contracts can be performed by reducing the nodes with poor performance in the blockchain, so that the processing efficiency of the blockchain data is improved.
Fig. 1 is an application scenario diagram of a method for executing a blockchain intelligent contract according to an embodiment of the present application, where, as shown in fig. 1, the method for executing a blockchain intelligent contract according to an embodiment of the present application is mainly applied to a blockchain intelligent contract execution scenario, where the scenario includes at least a plurality of blockchain nodes, and each node of a blockchain may perform data communication, where each node of the blockchain may perform transaction, transaction confirmation and broadcasting, and may also store related data in the blockchain, and the blockchain node may be any electronic device, for example, a mobile phone, or may also be a server device, which may perform the functions described above.
The present application is not particularly limited to the type and form of the entity device.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of an embodiment one of a method for executing a blockchain smart contract according to an embodiment of the present application, as shown in fig. 2, where the method for executing a blockchain smart contract according to the embodiment is applied to a first node in a blockchain system, and includes:
s101: and receiving a pre-written intelligent contract and a transaction request sent by the user.
In this step, in order to ensure the security of the user data, reduce the human error rate, and further execute the transaction by adopting the blockchain intelligent contract, the user first writes the intelligent contract in advance, then sends the intelligent contract in advance and the transaction request to the blockchain system, and the first node in the blockchain system receives the intelligent contract in advance and the transaction request sent by the user.
Specifically, the user may write the intelligent contract according to the transaction requirement, and the embodiment of the application does not limit the specific content of the intelligent contract.
S102: and executing the transaction request when detecting that the first node does not start the intelligent contract function, obtaining a transaction result, and generating a non-intelligent contract executing node identifier.
In this step, in order to reduce the time for compiling and executing the intelligent contract on the whole blockchain, after the blockchain system receives the intelligent contract and the transaction request sent by the user in the above step, it detects the first node, and when detecting that the first node does not open the intelligent contract function, it indicates that the first node does not have the condition for compiling and executing the intelligent contract, so that the first node cannot compile and execute the intelligent contract, only can execute the basic transaction, and then, according to the transaction request, the basic transaction is performed to obtain the transaction result, and a non-intelligent contract executing node identifier is generated, where the non-intelligent contract executing node identifier is used to indicate that the non-intelligent contract node does not open the intelligent contract function.
S103: and executing node identification according to the transaction result and the non-intelligent contract to generate a non-intelligent node block.
In this step, the transaction result and the non-intelligent contract executing node identifier are obtained through the data processing in the above step, and in order to be able to continue to perform data processing in the blockchain, a non-intelligent node block is generated according to the transaction result and the non-intelligent contract executing node identifier, where the non-intelligent node block includes an intelligent contract checking request, a transaction request and an intelligent contract, and the non-intelligent contract executing node identifier.
Specifically, in the block generation process, as shown in fig. 3, whether the current node generates a non-intelligent contract execution node identifier is detected, if the non-intelligent contract execution node identifier is generated, the non-intelligent node block is generated if the current node does not have the condition of compiling and executing the intelligent contract, and if the current node does not generate the non-intelligent contract execution node identifier, the intelligent node block is generated if the current node has the condition of compiling and executing the intelligent contract.
S104: and sending the non-intelligent node block to the next node.
In this step, after the first node generates the non-intelligent node block in the blockchain system, the non-intelligent node block is broadcast to the blockchain system and then sent to the next node.
Specifically, all newly added nodes of the non-intelligent contract executing node are provided with the non-intelligent contract executing node identification, and the nodes of the non-intelligent contract executing node do not perform data checksum calculation of the intelligent contract.
According to the execution method of the blockchain intelligent contract, the prefabricated intelligent contract and the transaction request sent by the user are received, when the fact that the first node does not start the intelligent contract function is detected, the transaction request is executed, a transaction result is obtained, a non-intelligent contract execution node identifier is generated, a non-intelligent node block is generated according to the transaction result and the non-intelligent contract execution node identifier, and the non-intelligent node block is sent to the next node.
Fig. 4 is a schematic flow chart of a second embodiment of a method for executing a blockchain smart contract according to the embodiment of the present application, as shown in fig. 4, where on the basis of the first embodiment, the method for executing a blockchain smart contract according to the present embodiment further includes:
s105: and receiving an intelligent contract detection request sent by the user.
In this step, before executing the blockchain smart contract, in order to reduce the time of compiling and executing the smart contract on the whole blockchain, and further improve the efficiency of blockchain data processing, the user sends a smart contract detection request to the blockchain system, and a first node of the blockchain receives the smart contract detection request sent by the user, where the smart contract detection request is used to instruct the first node to detect whether to start the smart contract function.
S106: according to the intelligent contract detection request, the intelligent contract determines whether to start the intelligent contract function.
In this step, after the first node receives the smart contract detection request sent by the user in the above step, it determines whether to start the smart contract function according to the smart contract detection request and the smart contract content.
Specifically, because the hardware performance of the nodes is different, the capability of compiling and executing the intelligent contracts is different, in order to reduce the influence of the node with lower hardware performance on the execution of the intelligent contracts, the node selects whether to start the intelligent contract function according to the hardware performance of the node.
Optionally, when there are fewer nodes in the blockchain, the data set cannot provide the conditions of the intelligent contracts, the intelligent contract function is not started, when the nodes which do not start the intelligent contracts occupy more than 30% of the total number of nodes in the blockchain, the function cannot be started, as shown in fig. 5, if the first node starts the intelligent contract function, the intelligent contracts sent by the user are received, and the intelligent contracts are executed according to the transaction request, if the first node does not start the intelligent contract function, the intelligent contracts sent by the user are received, but the intelligent contracts are not executed, and meanwhile, the non-intelligent contract executing node identifier is generated.
According to the execution method of the blockchain intelligent contract, which is provided by the embodiment, the intelligent contract detection request sent by the user is received, whether the intelligent contract function is started is determined according to the intelligent contract detection request, and whether the intelligent contract function is started is detected by the nodes in the blockchain, so that the compiling execution time of the intelligent contract is shortened, and the data processing efficiency is improved.
Fig. 6 is a flowchart of a third embodiment of a method for executing a blockchain smart contract according to the present application, as shown in fig. 6, where the method for executing a blockchain smart contract according to the present application is applied to other nodes in a blockchain system except for a first node, and includes:
s201: and receiving the non-intelligent node block sent by the last node.
In this step, other nodes except the first node in the blockchain system can receive the block sent by the previous node or can send the block to the next node, so that the first node sends the non-intelligent node block to other nodes and the other nodes receive the non-intelligent node block sent by the previous node in order to save the compiling execution time of the intelligent contract.
S202: according to the intelligent contract checking request, the intelligent contract and the non-intelligent contract executing node identification, whether the intelligent contract can be executed or not is determined.
In this step, after receiving the non-intelligent node block sent by the previous node, the other nodes read the non-intelligent node block, where the non-intelligent node block includes an intelligent contract checking request, a transaction request, a non-intelligent contract executing node identifier and an intelligent contract, where the non-intelligent contract executing node identifier is used to indicate that the previous node does not open an intelligent contract function, and further determine whether the intelligent contract can be executed.
Specifically, other nodes read whether the non-intelligent node block contains a non-intelligent contract executing node identifier, if the non-intelligent contract executing node identifier exists, the condition that the sub-block is generated by a node which does not open an intelligent contract function is not provided for compiling and executing the intelligent contract is indicated, then the sub-block is checked according to an intelligent contract checking request, whether the compiling and executing condition of the intelligent contract is met is determined, and accordingly whether the intelligent contract can be executed is determined.
S203: if it is determined that the intelligent contract cannot be executed, a block verification completion identification is generated.
In this step, whether the intelligent contract can be executed is checked through the steps, if it is determined that the intelligent contract cannot be executed, in order to reduce the execution time of the intelligent contract and reduce the compiling execution of the efficiency node, the compiling execution of the intelligent contract is not performed at the node, and a block check completion identifier is generated.
S204: and inserting the block verification completion identifier into the non-intelligent node block to obtain an updated non-intelligent node block, and updating the updated non-intelligent node block into the blockchain system.
In this step, after the block verification completion identifier is obtained in the above step, in order to ensure correct execution of the intelligent contract, the block verification completion identifier is inserted into the non-intelligent node block, and then the updated non-intelligent node block is updated into the blockchain system.
Specifically, in order to ensure correct execution of the intelligent contract, when other nodes perform verification according to the intelligent contract verification request, if the conditions for executing the intelligent contract are not met, the block verification completion identifier of the node needs to be read, and then the next node can be generated, so that the block verification completion identifier needs to be inserted into a non-intelligent node block, and then the updated non-intelligent node block is broadcasted into a blockchain.
According to the execution method of the blockchain intelligent contract, which is provided by the embodiment, the non-intelligent node block sent by the last node is received, the node identification is executed by the non-intelligent contract according to the intelligent contract checking request, whether the intelligent contract can be executed or not is determined, the block checking completion identification is inserted into the non-intelligent node block, the updated non-intelligent node block is obtained, the updated non-intelligent node block is updated into the blockchain system, the compiling execution time of the intelligent contract is shortened, and the data processing efficiency is improved.
Fig. 7 is a flow chart of a fourth embodiment of a method for executing a blockchain smart contract according to the embodiment of the present application, as shown in fig. 7, where on the basis of the third embodiment, the method for executing a blockchain smart contract according to the embodiment of the present application further includes:
s205: and if the intelligent contract can be executed, executing the intelligent contract, and generating an intelligent contract executing result.
In this step, after checking whether the smart contract can be executed in the above embodiment, if it is determined that the smart contract can be executed, in order to reduce the execution time of the smart contract and improve the data processing efficiency, the smart contract is executed, and an execution result of the smart contract is generated.
S206: and generating an intelligent contract block according to the intelligent contract execution result, and updating the intelligent contract block into the blockchain system.
In this step, after obtaining the execution result of the smart contract, as shown in fig. 8, after verifying that the node has the condition of executing the smart contract, an smart contract block is generated, where the smart contract block includes the execution result of the smart contract, the transaction request, and the smart contract block is updated into the blockchain system.
According to the execution method of the blockchain intelligent contract, if the fact that the intelligent contract can be executed is determined, the intelligent contract is executed, an intelligent contract execution result is generated, an intelligent contract block is generated according to the intelligent contract execution result, the intelligent contract block is updated to the blockchain system, compiling execution time of the intelligent contract is shortened, and data processing efficiency is improved.
Fig. 9 is a schematic flow chart of a fifth embodiment of a method for executing a blockchain smart contract according to the embodiment of the present application, as shown in fig. 9, on the basis of the fourth embodiment, the method for executing a blockchain smart contract according to the embodiment of the present application further includes:
s207: and receiving the intelligent node block sent by the last node.
In this step, the block received by the other node is a block of a previous node, wherein the block may be a non-intelligent node block or an intelligent node block, if the previous node has a condition of executing an intelligent contract, the intelligent contract is executed and an intelligent node block is generated and sent to the next node, and the next node receives the intelligent node block sent by the previous node.
S208: and executing other intelligent contracts according to other transaction requests, and generating other intelligent contract execution results.
S209: and generating other intelligent contract blocks according to the execution results of other intelligent contracts, and updating the other intelligent contract blocks into the blockchain system.
In step S208 and step S209, unlike the foregoing process of receiving the non-intelligent node block, after receiving the intelligent node block, the intelligent contract may be compiled and executed directly according to the transaction request without performing the intelligent contract check on itself. The specific execution process is the same as the specific execution process of step S205 and step S206 in the foregoing embodiment, and will not be described in detail here.
According to the execution method of the blockchain intelligent contract, which is provided by the embodiment, the intelligent node block sent by the last node is received, other intelligent contracts are executed according to other transaction requests, other intelligent contract execution results are generated, other intelligent contract blocks are generated according to other intelligent contract execution results, other intelligent contract blocks are updated into the blockchain system, after the node without the condition of executing the intelligent contracts receives the intelligent contract block generated by the node for executing the intelligent contracts, the intelligent contracts can be compiled and executed according to the intelligent contract block, and therefore the efficiency of processing the blockchain data is improved.
