Fig. 2 is a flowchart of a consistency detection method invoked by an intelligent contract according to an embodiment of the present application, and the present specification provides the method operation steps as described in the embodiment or the flowchart, but may include more or less operation steps based on conventional or non-creative labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. In practice, the system or server product may be implemented in a sequential or parallel manner (e.g., parallel processor or multi-threaded environment) according to the embodiments or methods shown in the figures. Specifically, as shown in fig. 2, the method may include:
s201, obtaining a target block chain, wherein the target block chain comprises at least one node.
In the embodiment of the present disclosure, it is first required to determine a target blockchain, which may be a blockchain network composed of nodes 111, 112, 113, 114, 115, and 116 in fig. 1.
And S203, injecting out-of-order control information into the original data content corresponding to the target block chain in a way of oriented section programming.
In this embodiment of the present specification, an out-of-order control code, that is, an AOP out-of-order control code, may be injected into an operation flow of a block chain in an Aspect-Oriented Programming (AOP) manner, and specifically, as shown in fig. 3, the injecting out-of-order control information into original data content corresponding to the target block chain in the Aspect-Oriented Programming manner may include:
s301, creating the out-of-order control information in a mode of oriented to section programming, wherein the out-of-order control information comprises delayed execution control information or repeated execution control information.
In this embodiment of the present specification, it is first necessary to write an AOP out-of-order control code, where the AOP out-of-order control code may include a delayed execution control code or a repeated execution control code, so that control is performed before and after the execution of the intelligent contract method, and the delayed or repeated execution thread out-of-order behavior is randomly added. The delayed execution control code may further include a random delay control code or a fixed delay control code, the random delay control code is used for controlling the intelligent contract to be randomly delayed for a period of time, the fixed delay control code is used for controlling the intelligent contract to be fixedly delayed for a period of time, the repeated execution control code may further include a random repeated execution code or a fixed repeated execution control code, the random repeated execution code is used for controlling the intelligent contract to be randomly and repeatedly executed for a certain number of times, and the fixed repeated execution code is used for controlling the intelligent contract to be fixedly executed for a certain number of times.
And S303, compiling the out-of-order control information.
In this embodiment of the present description, after writing the AOP out-of-order control code, the AOP out-of-order control code and the original data content corresponding to the block chain may be compiled, where the original data content corresponding to the block chain is the source code of the block chain. The compilation process may be performed by a compiler, which may be a compiler supporting AOP compilation, such as Aspectj compiler, which is a cut-plane oriented framework that extends the Java language, Aspectj defines the AOP syntax and has a specialized compiler to generate a Class file that complies with the Java byte coding specification. Where Java is a door-oriented object-programming language and Class is a prototype that defines variables and methods for a certain type of object.
S305, determining a cut-in position of the disorder control information in the original data content.
And S307, injecting the compiled disorder control information into the original data content according to the cut-in position.
In this embodiment of the present specification, in a process of compiling a source code of a target block chain, the source code may be first analyzed to determine a cut-in position where an AOP out-of-order control code needs to be injected, and then the compiled AOP out-of-order control code is inserted into the source code according to the cut-in position. Specifically, a schematic diagram of writing, compiling and deploying the AOP out-of-order control code is shown in fig. 4.
In one possible embodiment, after the AOP out-of-order control code is injected into the source code of the blockchain, modification of the AOP out-of-order control code becomes less easy, but many times, writing of the AOP out-of-order control code is not perfect, requiring modification of the AOP out-of-order control code initially injected into the source code according to actual operating requirements. In order to prevent the AOP out-of-order control code from being written dead and incapable of being modified conveniently, so that the requirements of random delay or fixed delay and random repetition times or fixed repetition times cannot be met, the design of the AOP out-of-order control code can be interacted with a shared memory Redis, and the AOP out-of-order control code can be controlled conveniently through an external script. Among them, Redis is a high performance distributed storage database. For example, if a certain execution needs to be repeatedly executed N times, where N is an integer greater than or equal to 1, the corresponding value in Redis modified, so that the AOP out-of-order control code is modified, and thus the intelligent contract can be repeatedly called according to the modified repeated execution times. For another example, if a certain execution requires a fixed delay for a period of time, the AOP out-of-order control code may be modified by modifying a corresponding value in Redis, so that the intelligent processor may perform the fixed delay execution for a period of time according to the modified fixed execution time, and perform other operations after a period of time.
In this embodiment of the present specification, by using the AOP control information, it is ensured that a source code of a blockchain service is not changed, and a control code is injected into an intelligently saved operation flow of a blockchain, so as to implement a situation that each thread controlling each node is out of order, repeated, or delayed in execution when an intelligent contract is executed. In addition, the AOP out-of-order control code can be controlled through an external script, so that the convenient control of the AOP out-of-order control code is improved, and the random or fixed delay, random repetition or fixed repetition requirements are conveniently realized. The lower product defects and risks of the block chain products, the higher maintainability of the block chain source codes and the convenient control of the AOP out-of-order control codes can provide guarantee for the consistency detection of the out-of-order calling of the intelligent contracts, so that the accuracy of the consistency detection result of the out-of-order calling of the intelligent contracts is ensured.
S205, intelligent contracts are deployed into each node, and the intelligent contracts comprise resource transfer rules or variable operation rules.
In the embodiment of the specification, in order to verify the consistency of the out-of-order calling of the intelligent contracts, the intelligent contracts are required to be deployed into each node, and the intelligent contracts can comprise at least one of resource transfer rules or variable operation rules.
In one possible embodiment, the resource transfer rules may include rules for transferring money in, out, which may be virtual money or digital money, etc.
In a possible embodiment, the variable operation rule may include an addition and subtraction operation rule of variables, the variables are classified according to their action ranges, may include global variables, local variables, and the like, and are classified according to storage occupation space, and may include integer variables, and the integer variables may further include long integer variables, short integer variables, character variables, floating point variables, and the like.
In this embodiment, before deploying an intelligent contract to each node, the intelligent contract code needs to be written, where the intelligent contract code is a code for running a currency transfer-in rule and a currency transfer-out rule or a code for running an addition or subtraction operation of a variable, and then the intelligent contract code is compiled, deployed, and issued to each node of a block chain that has been deployed.
Specifically, as shown in fig. 5, deploying an intelligent contract into each node, where the intelligent contract includes a resource transfer rule or a variable operation rule, and may include:

In practical application, a package sending script is compiled, a user can send a calling request (such as a transfer request and an addition and subtraction request) to each node, after each node receives the request of the user, various methods in an intelligent contract can be called with higher concurrency, for example, transfer to the intelligent saving mode, transfer the intelligent contract to the outside, add variables stored in the intelligent contract or subtract variables stored in the intelligent contract, and the like, and meanwhile, various methods in the intelligent contract are executed out of order on each node under the control of an AOP (automatic optic line) out-of-order control code, for example, whether to start out-of-order execution operation of the nodes, random or fixed delay, random or fixed repeated execution and the like.
Specifically, as shown in fig. 6, the controlling, by the out-of-order control information, each node to invoke the intelligent contract out-of-order to obtain an intelligent contract out-of-order invocation result corresponding to the node may include:
s601, in the process of calling the intelligent contract by each node, operating the delayed execution control information or the repeated execution control information.
In the embodiment of the present specification, a step of whether to start out-of-order operation of nodes may be set, for example, in the process of calling an intelligent contract by each node, when out-of-order control is required, the out-of-order execution operation of the nodes may be started, so that flexibility and controllability of consistency detection of the out-of-order calling of the intelligent contract are improved.
S603, controlling each node to delay or repeatedly execute at least one of a first operation, a second operation, a third operation or a fourth operation based on the delayed execution control information or the repeated execution control information; the first operation is an operation of transferring money of an external account into the intelligent contract corresponding to the node, the second operation is an operation of transferring money in the intelligent contract corresponding to the node out of the external account, the third operation is an operation of adding variables stored in the intelligent savings corresponding to the node, and the fourth operation is an operation of subtracting variables stored in the intelligent contract corresponding to the node.
In the embodiment of the present specification, after the out-of-order execution operation of the nodes is started, the AOP out-of-order control code may control each node to delay or repeatedly execute the money transfer-in and transfer-out operations, or the addition and subtraction operations of the variables stored in the intelligent contract. The deployment result diagram of the money transfer and the addition and subtraction operations of the variables may be as shown in fig. 7, where add in fig. 7 represents add, minus represents subtract, int256 addnum represents an addition function of a 256-bit integer, int256 minusnum represents a subtraction function of the 256-bit integer, and transfer represents a resource transfer.
In practical applications, the external account refers to an account outside the blockchain, one account exists in the intelligent contract of each node, the account existing in the intelligent contract is equivalent to an internal account, and the account existing outside the blockchain is an external account, such as an account of an external user.
In this embodiment of the present specification, after each node highly concurrently invokes the intelligent contract, an intelligent contract out-of-order invocation result corresponding to the node may be obtained from each node, where the intelligent contract out-of-order invocation result may include contract verification information, node verification information, and block chain function verification information, where the contract verification information is used to measure a change of the intelligent contract, the node verification information is used to measure a change of each node, and the block chain function verification information is used to measure a capability of each node to continue to execute a block chain operation.

S605, obtaining the account balance of the intelligent contract corresponding to each node or the numerical value of the variable stored in the intelligent contract from each node, and obtaining contract verification information corresponding to the node.
In one possible embodiment, the contract verification information may be obtained by calling a contract getteam method and a getNum method from each node to statically read an account balance of the smart contract, a value of a variable stored in the smart contract, and the like. Wherein, getBank method refers to a method of acquiring balance, and getNum method is a method of acquiring stored variable value. The view result diagram of the account balance of the intelligent contract or the value of the variable stored in the intelligent contract may be as shown in fig. 8, where the account balance of the intelligent contract of a certain node is 99990, and the value of the stored variable is 121.
In a possible embodiment, the query method can be declared in a view manner to obtain the account balance of the intelligent contract, the numerical value of the variable stored in the intelligent contract, and the like, wherein the view manner declares the query method to be a method for local search. By adopting the view mode statement query method, the balance and the stored variable value can be checked only through the local node (namely the node in the target block chain), and the check cannot be known from the network, so that the searched data is ensured to be based on the local node of the block chain instead of being acquired from other nodes, and the efficiency and the accuracy of acquiring the intelligent contract account balance and the stored variable value are ensured.
S607, at least one of the balance of the external account corresponding to the node, the height of the block chain or the transaction times is obtained from each node, and node verification information corresponding to the node is obtained.
In a possible embodiment, the node verification information may be obtained by reading information such as a balance of an external account corresponding to each node, a height of a blockchain corresponding to each node, and a transaction number of each node from each node.
And S609, acquiring log record information corresponding to the node from each node to obtain block chain function verification information corresponding to the node, wherein the block chain function verification information represents whether the node has the capacity of continuously calling the intelligent contract.

and acquiring the log record information corresponding to each node from each node.
And judging whether the log record information is abnormal or not.
And when log record information corresponding to the node is not abnormal, obtaining block chain function verification information representing the capability of the node for continuously calling the intelligent contract.
And when the log record information corresponding to the node is abnormal, obtaining block chain function verification information representing that the node does not have the capability of continuously calling the intelligent contract.
In practical applications, the ability to continue invoking the intelligent contract may be understood as continuing to perform blockchain operations (initiating transaction information to blockchain, etc. is normal).
S209, determining a consistency detection result of the intelligent contract out-of-order calling based on the obtained intelligent contract out-of-order calling result corresponding to each node.
In the embodiment of the description, when the intelligent contract out-of-order calling result is obtained, the intelligent contract out-of-order calling result needs to be analyzed, so that the consistency detection result of the intelligent contract out-of-order calling is determined.
In a possible embodiment, when the contract verification information, the node verification information and the blockchain function verification information of each node are all consistent, and each node has the capability of continuously calling the intelligent contract, the consistency detection of the intelligent contract out-of-order calling is considered to be passed, otherwise, the consistency detection of the intelligent contract out-of-order calling is considered to be not passed. For example, as shown in fig. 1, if there are 6 nodes in the blockchain network, when the contract verification information, the node verification information, and the blockchain function verification information in the 6 nodes are all consistent, and the 6 nodes all have the capability of continuing to invoke the intelligent contract, it is considered that the consistency detection invoked out of order by the intelligent contract is passed.
In a feasible embodiment, in order to improve the efficiency of consistency detection of intelligent contract out-of-order calling, the consistency detection of intelligent contract out-of-order calling can be determined without the fact that data of each node is identical, and on the premise that network consensus is not affected, as long as the data of a preset number of nodes are identical, for example, the data of 2/3 nodes are identical, and 2/3 nodes have the capability of continuously calling the intelligent contract, each node can be considered to pass the consistency detection, otherwise, the consistency detection is not considered to pass. For example, as shown in fig. 1, a total of 6 nodes in the blockchain network, when the contract verification information, the node verification information, and the blockchain function verification information of 4 nodes (e.g., nodes 111, 112, 114, 116) in the 6 nodes are all consistent, and the 4 nodes all have the capability of continuing to invoke the intelligent contract, it is considered that each node passes the consistency detection invoked out of order by the intelligent contract.
Specifically, as shown in fig. 9, the determining a consistency detection result of the intelligent contract out-of-order call based on the obtained intelligent contract out-of-order call result corresponding to each node may further include:
and S901, obtaining the contract verification information and the nodes with consistent node verification information to obtain a target node set.
And S903, when the number of the target nodes is larger than a preset threshold value and the block chain function verification information of each target node indicates that the target nodes have the capacity of continuously calling the intelligent contracts, determining the consistency detection of the disordered calling of the intelligent contracts.
S905, when the number of the target nodes is smaller than or equal to the preset threshold value, determining that the consistency detection of the out-of-order calling of the intelligent contracts does not pass.
Fig. 10 is a schematic diagram illustrating a working principle of a method for detecting consistency of intelligent contract invocation according to an embodiment of the present application, and as shown in fig. 10, a random or fixed delay and a random or fixed repetitive AOP out-of-order control code are first injected into a source code corresponding to a block chain, then an intelligent contract including an addition and subtraction operation of a money transfer-in/out and/or storage variable is injected into each node in the block chain, and after each node receives a call request from an external user, each node starts invoking the intelligent contract, and at the same time, a node out-of-order execution operation is started to control each node to delay or repeat the addition and subtraction operation of the money transfer-in, transfer-out and/or storage variable, so as to obtain a contract account, a value of the storage variable in the contract, a balance, a block chain height, a transaction number corresponding to each node, and a value of the balance in the contract, a balance, an external account balance, a block chain height, and a transaction number corresponding to each node, And recording log and other out-of-order calling results, and finally judging whether all the data of a preset number of nodes are consistent, wherein the preset number of nodes can have the capability of continuously executing the block chain operation, if so, the consistency detection result of the out-of-order calling of the intelligent contract by each node of the block chain is considered to be passed, and otherwise, the consistency detection result is considered to be not passed. In the application, because AOP control technology has the advantage of not changing the source code, the defects and risks of block chain products can be reduced, the maintainability of the block chain source code is ensured, in addition, the intelligent contracts are concurrently called from different dimensionalities, so that the out-of-order calling results of different dimensionalities are obtained, and the accuracy and the reliability of the consistency detection of the out-of-order calling of the intelligent contracts can be obviously improved.
