Based on the above scenario of blockchain-based blockchain parallel transaction, an embodiment of a blockchain-based blockchain parallel transaction method is provided.

As shown in fig. 2, fig. 2 is a schematic flowchart of an embodiment of a blockchain parallel transaction method in the embodiment of the present application, where the image processing method includes the following steps 201 — 204:

201. acquiring each intelligent contract transaction to be processed and transaction configuration information of the intelligent contract transaction;

in this embodiment, the blockchain parallel transaction method is applied to blockchain parallel transaction equipment, where the blockchain parallel transaction equipment is a node equipment in a blockchain, where the type of the blockchain parallel transaction equipment is not specifically limited, for example, the blockchain parallel transaction equipment may be an intelligent terminal or a server, and in this embodiment, the intelligent terminal is taken as an example for description.

Specifically, the blockchain parallel transaction device is configured to receive an intelligent contract transaction to be processed, determine a mutually exclusive variable behavior of the intelligent contract transaction according to transaction configuration information of the intelligent contract transaction, a transaction contract and an intelligent contract method, determine a parallel contract transaction in the intelligent contract transaction by performing dependency analysis on the mutually exclusive variable behavior, and perform parallel execution on the parallel contract transaction. Wherein the parallel contract transactions are intelligent contract transactions having no dependency relationship with other intelligent contract transactions.

Specifically, the blockchain parallel transaction device receives a transaction parallel request in the operation process, and responds to the transaction parallel request to perform transaction parallel processing on the intelligent contract transaction. The transaction parallel request may be actively triggered by a user, for example, the user actively triggers the transaction parallel request by clicking a transaction parallel button in the blockchain parallel transaction device, and optionally, the transaction parallel request may also be automatically triggered by the blockchain parallel transaction device, for example, the blockchain parallel transaction device is preset with a transaction parallel process, detects an intelligent contract transaction in the blockchain in real time, and automatically triggers the transaction parallel request after the intelligent contract transaction meets a preset parallel transaction policy.

Specifically, after receiving the parallel transaction request, the blockchain parallel transaction device acquires a block in the parallel transaction request, analyzes the intelligent contract transaction in the block, acquires each intelligent contract transaction corresponding to the parallel transaction request, and acquires transaction configuration information in each intelligent contract transaction. The transaction configuration information is a transaction parameter output by each node device for generating the intelligent contract exchange, and optionally, the transaction configuration information includes contract address information, a function identifier of an intelligent contract method, and a transaction input parameter.

202. Acquiring a trading contract and an intelligent contract method corresponding to the intelligent contract trade, and determining target field operation information of the intelligent contract trade according to the trading contract and the intelligent contract method;

after acquiring the transaction configuration information, the block chain parallel transaction equipment acquires a transaction contract and an intelligent contract method corresponding to the intelligent contract transaction through the transaction configuration information, and determines target field operation information of the intelligent contract transaction according to the transaction contract and the intelligent contract method. Wherein the trading contract is a specific intelligent contract in the block chain; the intelligent contract method is a contract method called by the current intelligent contract transaction in the characterization transaction contract; the target field operation information is the operation identification which characterizes the target field and the mutual exclusion variable which are related to the intelligent contract transaction.

Specifically, the blockchain parallel transaction device obtains the transaction type of the intelligent contract transaction in advance, and determines the transaction contract and the target field operation information of the intelligent contract transaction through the transaction type of the intelligent contract transaction and the contract address information associated with the intelligent contract transaction. Optionally, the transaction types of the intelligent contract transaction include a contract deployment transaction type, a contract lifecycle management transaction type, and a contract invocation transaction type.

Specifically, the block chain parallel transaction device obtains a contract transaction type of an intelligent contract transaction, if the contract transaction type of the intelligent contract transaction is determined to be a contract deployment transaction, determines a contract account to be deployed according to reading of transaction configuration information, reads a random numerical value in a target field of the contract account to be deployed, performs hash operation on the random numerical value to obtain an updated intelligent contract address, adds 1 to a value of the target field, and generates an exclusive variable behavior of the contract deployment transaction according to the contract account to be deployed, the target contract address and a field operation identifier. Wherein the contract account to be deployed is a from account, and the contract deployment transaction is an intelligent contract transaction for modifying a target field (nonce value) in the from account and creating ledger data of a new contract; the transaction configuration information is a contract account address to be deployed.

Specifically, the blockchain parallel transaction device obtains a transaction type of the intelligent contract, and if the contract transaction type of the intelligent contract transaction is determined to be a contract lifecycle management transaction, the contract lifecycle management contract transaction is a transaction behavior for modifying ledger data in a to account. Thus, the contract lifecycle management contract transactions may affect the account execution logic that invokes the to contract, i.e., be considered mutually exclusive with all transactions that invoke the to contract. Therefore, the blockchain parallel transaction device acquires the field operation identifier corresponding to the contract life cycle management transaction and the transaction configuration information, and generates the mutually exclusive variable behavior of the life cycle management transaction. Wherein the transaction configuration information is contract address information of the to contract.

Specifically, after determining that the transaction type of the intelligent contract transaction is a contract calling transaction type, the blockchain parallel transaction device queries the contract interface file of each intelligent contract through the contract address information of the intelligent contract transaction, so as to obtain the contract interface file matched with the contract address information, and thus obtain the transaction contract corresponding to the intelligent contract transaction.

After obtaining a trading contract corresponding to the intelligent contract trade, the block chain parallel trading device analyzes the trading contract to determine contract methods included in the trading contract, compares method identifications of the contract methods with function identifications of the intelligent contract trade, obtains a target contract method successfully compared, and determines that the target contract method is the intelligent contract method of the intelligent contract trade.

After the block chain parallel transaction equipment acquires the intelligent contract method, the instruction analysis is also carried out on the intelligent contract method, and a target field and a field operation identifier operated in the intelligent contract method are acquired, so that target field operation information in the intelligent contract method is acquired.

Optionally, the target field operation information may be obtained when the user constructs an intelligent contract transaction based on the client, or may be obtained after the intelligent contract transaction is linked up, and after the target field operation information is obtained, the target field operation information is encoded into a contract interface file of the transaction contract by the block chain parallel transaction.

203. Generating a mutually exclusive variable behavior of the intelligent contract transaction according to the target field operation information and the transaction configuration information;

after obtaining the target field operation information of the intelligent contract transaction, the blockchain parallel transaction device generates a mutual exclusion variable behavior of the intelligent contract according to the target field operation information and the transaction input parameters in the transaction configuration information, wherein the mutual exclusion variable behavior is a mutual exclusion variable representing the intelligent contract transaction and behavior information of operation aiming at the mutual exclusion variable. The mutually exclusive variable behavior comprises a mutually exclusive variable and a field operation identifier.

Specifically, the blockchain parallel transaction device constructs a mutual exclusion variable template according to the target field in the target field operation information and the contract address information, and inputs the transaction input parameters in the transaction configuration information into the mutual exclusion variable template to obtain the mutual exclusion variable of the intelligent contract transaction. The mutual exclusion variable includes any one or more of an account address and a mutual exclusion field. The account address is a mutually exclusive variable used for identifying the range of operating the account book data, namely, the transaction contract address of the intelligent contract transaction, and can be represented by a character string array, the range of operating the account book data is gradually reduced from front to back, and the smaller the range is, the higher the concurrency degree can be achieved. The mutually exclusive field is a field that defines the ledger scope of the operation as being under the transaction contract account.

Optionally, the number of elements in the mutex variable generated by the blockchain parallel transaction device may be one or more, if there is only one element in the mutex variable, that is, the mutex variable only includes an account address element, that is, the ledger modification range that identifies the mutex variable includes all data under an account specified by the ledger address; if the number of the elements in the mutex variable identifier is two, that is, the mutex variable identifier includes an account address element and a mutex field, the ledger modification range of the mutex variable is determined to be all data of the specified mutex field under the account address. And if the number of the elements in the mutual exclusion variable is more than or equal to three, namely the mutual exclusion variable also comprises an element key corresponding to the transaction input parameter, identifying the ledger modification range of the mutual exclusion variable as some data of the specified mutual exclusion field under the account address.

Specifically, after the block chain parallel transaction device generates the mutual exclusion variable, the field operation identifier corresponding to the mutual exclusion variable in the field operation information is also obtained, and the mutual exclusion variable and the field operation identifier are associated to obtain the mutual exclusion variable behavior of the intelligent contract transaction.

204. And performing dependency analysis on each intelligent contract transaction according to the mutually exclusive variable behavior of each intelligent contract transaction to obtain each parallel contract transaction in each intelligent contract transaction, and executing each parallel contract transaction in parallel.

After acquiring all the mutually exclusive variable behaviors of the intelligent contract transactions to be processed, the block chain parallel transaction equipment also performs dependence analysis on the intelligent contract transactions according to the mutually exclusive variable behaviors of the intelligent contract transactions, thereby determining whether the intelligent contract transactions can be processed in parallel, acquiring the parallel contract transactions which can be processed in parallel in the intelligent contract transactions, and executing the parallel contract transactions in parallel.

Specifically, as shown in fig. 3, fig. 3 is a scene diagram of an embodiment of a mutual exclusion variable tree in the embodiment of the present application. In the proposal, the mutually exclusive variable behavior of the intelligent contract transactions can be represented by the tree structure, and the dependency analysis is carried out on each intelligent contract transaction according to the tree structure and the mutually exclusive variable behavior to form a mutually exclusive variable tree, so that the dependency relationship in each intelligent contract transaction is determined according to the mutually exclusive variable tree.

The initialized mutex variable tree only has one root node, and the root node represents data of the whole account book. In the mutex variable tree, starting from a root node to any node, the node can be called a path, and a character string array formed by edges on the path is actually a mutex variable. The construction of the mutual exclusion variable tree is based on the mutual exclusion variable behavior, and the addition of a mutual exclusion variable behavior to the mutual exclusion variable tree can be regarded as the construction of a path in the mutual exclusion variable tree. After the block chain parallel transaction equipment constructs the mutual exclusion variable tree according to the mutual exclusion variable behaviors of the intelligent contract transactions to be processed, the dependency relationship of each intelligent contract transaction is determined through the mutual exclusion variable tree, and therefore the parallel contract transactions which do not have the dependency relationship with each intelligent contract transaction are obtained.

After acquiring parallel contract transactions in intelligent contract transactions, the block chain parallel transaction equipment inputs the parallel contract transactions into a preset transaction parallel execution model, improves the transaction parallel execution model to perform parallel processing on each parallel contract transaction, and performs serial processing on the intelligent contract transactions with dependency relationships according to a preset transaction sequence.

In the embodiment, the blockchain parallel transaction equipment acquires each intelligent contract transaction to be processed and transaction configuration information of each intelligent contract transaction; acquiring a trading contract and an intelligent contract method corresponding to each intelligent contract, and determining target field operation information of intelligent contract trading according to the trading contract and the intelligent contract method; after the target field operation information is acquired, mutually exclusive variable behaviors of the intelligent contract transactions are generated according to the target field operation information and the transaction configuration information, dependence analysis is performed on the intelligent contract transactions according to the mutually exclusive variable behaviors of the intelligent contract transactions, so that parallel contract transactions in the intelligent contract transactions are determined, the parallel contract transactions are executed in parallel, the transaction behavior analysis granularity is improved, the dependence analysis accuracy is improved, and the parallelism degree and completeness of parallel contract transaction processing are further ensured.

Fig. 4 is a flowchart illustrating an embodiment of generating a mutex variable across contract address information in a blockchain parallel transaction method according to an embodiment of the present disclosure.

In this embodiment, if it is detected that a cross-contract invoking behavior exists in an intelligent contract transaction, a mutual exclusion variable behavior analysis is performed on the cross-contract invoking behavior, specifically, the method includes steps 301-304:

301. acquiring a contract transaction type of the intelligent contract transaction;

302. if the contract transaction type is a contract calling transaction type, acquiring cross-contract address information associated with the intelligent contract method and a second contract corresponding to the cross-contract address information;

303. acquiring cross contract field operation information associated with the intelligent contract method in the second contract, and generating a cross contract calling strategy according to the second contract and the cross contract field operation information;

304. and generating a mutual exclusion variable behavior of the intelligent contract transaction according to the target field operation information, the cross-contract calling strategy and the transaction configuration information.

After acquiring contract address information associated with each intelligent contract transaction, if the contract address information is multiple, the blockchain parallel transaction device determines that the intelligent contract transaction has a cross-contract calling behavior, and determines a mutually exclusive variable behavior of the intelligent contract transaction according to the cross-contract calling behavior.

Specifically, the blockchain parallel transaction device obtains cross-contract address information associated with the intelligent contract transaction method, and obtains a second contract corresponding to the cross-contract address information and a contract interface file corresponding to the second contract according to the cross-contract address information.

And after acquiring the contract interface file, the block chain parallel transaction equipment also acquires a cross-contract calling signature array in the intelligent contract method, and acquires mutually exclusive field information in the second contract according to the cross-contract calling signature array, so as to acquire cross-contract field operation information associated with the intelligent contract method in the second contract.

Specifically, after acquiring the cross-contract calling signature array, the block chain parallel transaction device analyzes the cross-contract calling signature array to obtain each method signature in the cross-contract calling signature array, traverses the contract interface file corresponding to the second contract through the method signature, and acquires cross-contract field operation information corresponding to the method signature in the contract interface file, wherein the cross-contract field operation information includes a cross-contract field and a cross-contract operation identifier, and the block chain parallel transaction device generates a cross-contract calling policy according to the acquired second contract and the cross-contract operation field.

After acquiring a cross-contract calling strategy, the block chain parallel transaction equipment also constructs a mutual exclusion variable template according to a target field in target field operation information of intelligent contract transaction and contract address information, and inputs transaction configuration information into the mutual exclusion variable template to obtain a first mutual exclusion variable of the intelligent contract transaction; and generating a second mutual exclusion variable of the intelligent contract transaction according to the cross-contract address information in the cross-contract calling strategy.

And after the block chain parallel transaction equipment acquires the first mutual exclusion variable and the second mutual exclusion variable, generating a mutual exclusion variable behavior of the intelligent contract according to the field operation identifier, the first mutual exclusion variable and the second mutual exclusion variable.

Optionally, in a specific embodiment, the intelligent contract transaction tx1 acquired by the blockchain parallel transaction device and the contract address information of the intelligent contract transaction is determined to be addrCC, the function identifier of the intelligent contract transaction is func4, and the transaction input parameters in the transaction configuration information are [ "cc1", "cc2" ]. The block chain parallel transaction equipment acquires a transaction contract CC and an interface file ABI _ CC file corresponding to the transaction contract according to contract address information, acquires exclusive field information corresponding to the function identifier func4 in the ABI _ CC file, determines a first exclusive variable [ addrCC, fd, CC1] corresponding to the intelligent transaction method func4, namely determines that the exclusive field information represents that data in the fd [ CC1] range under the addrCC address can be operated, and also acquires a field operation identifier R corresponding to the first exclusive variable in the intelligent transaction method func4, and determines that the first exclusive variable represents that data in the fd [ CC1] range under the addrCC address can be read.

The block chain parallel transaction equipment also acquires cross contract address information addrCB in the intelligent contract method func4, acquires a second contract CB according to the cross contract address information, acquires a cross contract interface file ABI _ CB corresponding to the second contract CB, acquires a second mutually exclusive variable (addrCB, fc) in the ABI _ CB file according to a cross contract signature array [ (addrCB, [ "func3" ]) ], and determines that the second mutually exclusive variable RW variable is data representing the fc range under the addrCB address to be subjected to read-write operation.

After acquiring the first mutual exclusion variable [ addrCC, fd, cc1], the second mutual exclusion variable [ addrCB, fc ] and the corresponding field operation identifier, the block chain parallel transaction device generates a mutual exclusion variable behavior corresponding to the intelligent contract transaction. The mutual exclusion variable behavior of the intelligent contract transaction tx1 is shown in the following table:

after the block chain parallel transaction device obtains the mutual exclusion variable behaviors corresponding to the intelligent contract transactions in the above mode, the dependency analysis is performed on the intelligent contract transactions according to the mutual exclusion variable behaviors, so that the dependency relationship of the intelligent contract transactions is determined.

In this embodiment, the block chain parallel transaction device obtains the cross-contract address information associated with the intelligent contract method and the second contract corresponding to the cross-contract address information; acquiring cross contract field operation information associated with the intelligent contract method in the second contract, and generating a cross contract calling strategy according to the second contract and the cross contract field operation information; and generating a mutual exclusion variable behavior of the intelligent contract transaction according to the target field operation information, the cross-contract calling strategy and the transaction configuration information.

Based on the above embodiment, in this proposal, after acquiring the mutual exclusion variable behavior of each intelligent contract transaction, the blockchain parallel transaction device performs dependency analysis on each intelligent contract transaction according to the mutual exclusion variable behavior, so as to determine parallel contract transactions that can be executed in parallel, specifically, including step 401 — step 403:

401. acquiring a mutual exclusion variable of a mutual exclusion variable behavior corresponding to each intelligent contract transaction;

402. if a target mutual exclusion variable behavior group with mutually exclusive variables matched exists, acquiring a target field operation identifier of each target mutual exclusion variable behavior in the target mutual exclusion variable behavior group;

403. and performing dependency analysis on target intelligent contract transactions corresponding to the target mutual exclusion variable behaviors according to the target field operation identification to obtain parallel contract transactions in each target intelligent contract transaction, and executing each parallel contract transaction in parallel.

In this embodiment, after acquiring the mutually exclusive variable behavior corresponding to each intelligent contract transaction, the blockchain parallel transaction device performs dependency analysis on each intelligent contract transaction according to the mutually exclusive variable behavior.

Specifically, the block chain parallel transaction device generates an initialized mutual exclusion variable tree, inputs each mutual exclusion variable behavior into the mutual exclusion variable tree, and analyzes the dependency relationship of each intelligent contract transaction through the mutual exclusion variable tree and the mutual exclusion variable behavior.

And the block chain parallel transaction equipment carries out dependence analysis on partial mutual exclusion variable behaviors in advance to obtain partial mutual exclusion variable behaviors without dependence, inputs the partial mutual exclusion variable behaviors into the initialized mutual exclusion variable tree, and generates initial branch nodes of the mutual exclusion variable tree.

After the block chain parallel transaction device generates the initial branch node, the dependency analysis is carried out on the residual mutex variable behaviors, the mutex variables of the residual mutex variable behaviors are obtained, and the mutex variables are compared, so that a mutex variable comparison result is obtained.

Optionally, if the mutual exclusion variable comparison result is that the mutual exclusion variable is different from other mutual exclusion variables, that is, the mutual exclusion variable is not matched with the mutual exclusion variables of other mutual exclusion variable behaviors, the blockchain parallel transaction device generates a new branch node of the mutual exclusion variable tree, and records the mutual exclusion variable behavior into the branch node.

Optionally, if the mutex variable comparison result indicates that a mutex variable identical to the mutex variable exists, that is, a mutex variable behavior matched with the mutex variable exists, the blockchain parallel transaction device sets the mutex variable behavior matched with the mutex variable as a target mutex variable behavior, stores the target mutex variable behavior in a corresponding target mutex variable behavior group in association, and generates a mutex sub-branch corresponding to the target mutex variable behavior group.

Specifically, after generating the target mutual exclusion variable behavior group, the blockchain parallel transaction device also acquires a target field operation identifier in the target mutual exclusion variable behavior group, and judges whether dependency exists in each target mutual exclusion variable behavior through the target field operation identifier, so as to obtain parallel contract transactions in target intelligent contract transactions.

Optionally, the blockchain parallel transaction device obtains each target field operation identifier in the target mutually exclusive variable behavior group, if the target field operation identifier of the target mutually exclusive variable behavior is a read-only operation identifier, the blockchain parallel transaction device traverses a target branch associated with the target mutually exclusive variable in the mutually exclusive variable tree, and if the target field operation identifier corresponding to the target branch is a read-write operation identifier or a write-in operation identifier, it is determined that the target intelligent contract transaction corresponding to the target branch and the intelligent contract transaction corresponding to the target mutually exclusive variable behavior are mutually dependent contract transactions.

Optionally, the blockchain parallel transaction device obtains each target field operation identifier in the target mutually exclusive variable behavior group, and if the target field operation identifier is a write operation identifier, the blockchain parallel transaction device obtains a target branch associated with the target mutually exclusive variable in the mutually exclusive variable tree, and determines that the target intelligent contract transactions corresponding to the target branch are mutually dependent contract transactions with the intelligent contract transactions of the target mutually exclusive variable behavior corresponding to the write operation identifier.

And the block chain parallel transaction equipment groups the intelligent contracts according to the dependency relationship of the intelligent contract transactions to obtain the parallel contract transactions in the intelligent contract transactions, and inputs the parallel contract transactions into the grouping parallel model to execute the parallel contract transactions in parallel.

Optionally, in an embodiment, the mutually exclusive variable behavior corresponding to the intelligent contract transaction acquired by the blockchain parallel transaction device is shown in the following table:

and after the block chain parallel transaction equipment constructs the mutual exclusion variable tree according to the mutual exclusion variable behaviors of each intelligent contract transaction, performing dependence analysis through the mutual exclusion variable behaviors and the mutual exclusion variable tree.

And traversing the mutex variable tree by the blockchain parallel transaction equipment, and determining a target mutex variable behavior group [ tx1, tx5], [ tx2], [ tx3, tx7] and [ tx4, tx6] of the same mutex variable in the mutex variable tree. And after the block chain parallel transaction equipment acquires the target mutual exclusion variable behavior group again, acquiring a target field operation identifier in the target mutual exclusion variable behavior group, and determining whether the song target mutual exclusion variable behaviors in the target mutual exclusion variable behavior group have a dependency relationship or not through the target field operation identifier.

Specifically, the blockchain parallel transaction device acquires a target field operation identifier of a target exclusive variable behavior tx5 as a read-only operation identifier, acquires a target field operation identifier of another target exclusive variable behavior tx1, and determines that the operation of tx1 is also a read-only operation, and then the blockchain parallel transaction device determines that there is no dependency relationship between the target exclusive variable behaviors tx1 and tx5, and determines that the target exclusive variable behaviors tx1 and tx5 are parallel contract transactions.

Specifically, the blockchain parallel transaction device acquires a target field operation identifier of a target exclusive variable behavior tx6 as a read-only operation identifier, acquires a target field operation identifier of another target exclusive variable behavior tx4, determines that the operation of tx4 is a write operation, that is, the target field operation identifier of tx4 is a write operation identifier, determines that a dependency relationship exists between the target exclusive variable behaviors tx4 and tx6, and sets tx4 and tx6 as the same exclusive variable branch of the exclusive variable tree.

Specifically, the blockchain parallel transaction device acquires a target field operation identifier of a target mutex variable behavior tx7 as a read-only operation identifier, acquires a target field operation identifier of another target mutex variable behavior tx3, determines that the operation of tx3 on the mutex variable is a read-write operation, that is, the target field operation identifier of tx3 is a read-write operation identifier, determines that a dependency relationship exists between the target mutex variable behaviors tx3 and tx7, and sets tx3 and tx7 as the same mutex variable branch of the mutex variable tree.

And the block chain parallel transaction equipment executes the intelligent contract transactions of different mutually exclusive variable branches in the mutually exclusive variable tree in parallel.

In this embodiment, the blockchain parallel transaction device acquires the mutual exclusion variable of the mutual exclusion variable behavior corresponding to each intelligent contract transaction; if a target mutual exclusion variable behavior group with mutually exclusive variables matched exists, acquiring a target field operation identifier of each target mutual exclusion variable behavior in the target mutual exclusion variable behavior group; and performing dependency analysis on target intelligent contract transactions corresponding to the target mutual exclusion variable behaviors according to the target field operation identifiers to obtain parallel contract transactions in each target intelligent contract transaction, and executing each parallel contract transaction in parallel. The dependency analysis of each intelligent contract transaction is realized through the mutual exclusion variable behavior, and the accuracy of the dependency analysis is improved.
