Detailed Description

In order that those skilled in the art will better understand the technical solutions in this specification, a clear and complete description of the technical solutions in one or more embodiments of this specification will be provided below with reference to the accompanying drawings in one or more embodiments of this specification, and it is apparent that the one or more embodiments described are only a part of embodiments of this specification, not all embodiments. All other embodiments, which can be made by one or more embodiments of the present disclosure without inventive faculty, are intended to be within the scope of the present disclosure.

A blockchain is typically made up of several blocks in which time stamps corresponding to the time of creation of the block are recorded, respectively, all of which constitute a temporally ordered chain of data strictly in accordance with the time stamps recorded in the block. For real data generated in the physical world, the real data can be constructed into a standard transaction (transaction) format supported by a blockchain, the standard transaction (transaction) format is issued to the blockchain, node equipment in the blockchain performs consensus processing on received transactions, and after the consensus is achieved, node equipment serving as an accounting node in the blockchain packages the transactions into blocks, and lasting certification is performed in the blockchain.

Tuple (tuple) is the basic concept in a relational database, a relation is a table, each row in the table (i.e., each record in the database) is a tuple, and each column is an attribute. In a two-dimensional table, tuples are also called rows.

The method signature is composed of a method name and a list of parameters (order and type of parameters of the method).

In view of the problems mentioned in the background art, the processing performance of the existing blockchain system for processing transactions is generally weaker than that of the conventional system, and in order to improve the transaction processing capability, a batch transaction processing scheme is proposed. At the beginning of transaction processing, bulk transaction intelligence contracts may be deployed on a blockchain network. In this way, the target user terminal can use the address of the intelligent contract for batch transaction as the contract address, and splice the transaction parameters of a plurality of transactions to be submitted to obtain batch transaction parameters, so that the plurality of transactions are combined and created into one batch transaction; after signing the batch transaction, sending the batch transaction signature to a blockchain node for verification, after the verification passes and the consensus packaging is carried out, calling a batch transaction intelligent contract corresponding to a contract address to analyze batch transaction parameters so as to sequentially carry out format verification on each transaction, and if all the verification is correct, sequentially calling a transaction sub-contract corresponding to a transaction sub-contract address of each transaction to process the corresponding transaction. Therefore, when the transaction is processed, only one signature and verification are needed, the volume of data of batch transaction is smaller than that of a plurality of transaction data, the processing capacity of block chain tension is greatly relieved, and the transaction processing efficiency is improved. In addition, the batch transaction scheme can save the transaction cost of the user for the situation of operating according to the transaction times.

Referring to FIG. 1, a schematic diagram of a processing system architecture for performing batch transactions based on blockchains is provided in accordance with an embodiment of the present disclosure. In this scenario, the target user terminal 102 may be a hardware electronic device or a software client that may communicate with at least one blockchain node 106 in the blockchain network 104. Similarly, the blockchain nodes 106 may also be hardware electronics or software clients, with the difference that each blockchain node 106 is provided with blockchain modules to collectively maintain the blockchain network 104 through deployed intelligent contracts. In this specification, not only transaction execution-related smart contracts (i.e., one or more transaction sub-contracts) but also bulk transaction smart contracts are deployed in the blockchain node 106 to enable bulk processing of multiple transactions.

Example 1

Referring to fig. 2, a schematic step diagram of a processing method for executing batch transactions based on a blockchain according to an embodiment of the present disclosure is applied to a processing system including a target user terminal and a blockchain network, where the blockchain network includes a plurality of blockchain nodes, and at least a batch transaction smart contract is deployed on the blockchain network; wherein, the method for batch transaction is provided in the intelligent batch transaction contract, and the method can have and has only one parameter, and the parameter type is bytes.

The processing method may include the steps of:

Step 202: the target user terminal creates a batch transaction based on a plurality of transactions to be submitted, signs the batch transaction, and sends the signed batch transaction to at least one blockchain node in the blockchain network for verification; the batch transaction parameters of the batch transaction are determined based on the transaction parameters of each transaction in the plurality of transactions, and the contract address of the batch transaction is the address of the intelligent contract of the batch transaction; wherein the transaction parameters include: transaction subcontract address and method data.

It should be appreciated that the present description embodiments do not limit the number of transactions to be submitted, so long as the upper limit of the transaction transmission data size is not exceeded. The plurality of transactions to be submitted can be a plurality of transactions submitted by the user at one time or a plurality of transactions cached by the user submitted in multiple times.

Optionally, when creating a batch transaction based on a plurality of transactions to be submitted, the target user terminal may determine a data structure of each transaction respectively, and sequentially splice the determined plurality of data structures to obtain batch transaction parameters; and using the address of the intelligent contract for batch transaction as a contract address to create a batch transaction.

In other words, the target user terminal determines the bulk transaction parameters and the contract address of one bulk transaction to be created based on the transaction parameters of each of the plurality of transactions to be submitted. It should be appreciated that the transaction format of the bulk transaction is different from the transaction format of a common single transaction.

A common single transaction contains two parameters: target contract address and method data. Where the target contract address, i.e., the transaction sub-contract address corresponding to a single transaction, the method data is essentially a combination of method signatures and method parameters, and the method signatures are a combination of method names and parameter lists (order and type of method parameters). In the embodiment of the present specification, both the target contract address and the method data are understood as character strings, wherein the target contract address is a fixed length, and the method data is a variable length, i.e., the length is not fixed.

Batch transactions also contain two parameters: target contract address and bulk transaction parameters. The target contract address is the address of a batch transaction intelligent contract, and batch transaction parameters are spliced together by a data structure of a plurality of transactions. And the data structure of each transaction may be determined based on the transaction parameters of the transaction, in particular, the target user terminal determines the data length of the method data of the current transaction; and splicing the subcontract address, the data length and the method data corresponding to the current transaction to form a tuple structure. In fact, the tuple structure is only a format of a preferred batch transaction parameter, and the tuple structure can be simply spliced end to end. It will be appreciated that the subcontract address and the determined data length of each transaction are fixed lengths and the method data is variable length.

That is, when a user needs to send a batch transaction, firstly, calculating the data length of the method signature+the method parameter of the single sub-transaction, and then splicing the three parameters of the target contract address, the data length, the method signature+the method parameter to form a tuple structure: tuple (target contract address, data length, method signature+method parameters). And finally, signing the batch transaction, and sending the signed batch transaction to one or more blockchain nodes on the blockchain for verification.

For example, assuming that a batch transaction consists of transaction 1 (id 1; parameter 1), transaction 2 (id 2; parameter 2) and transaction 3 (id 3; parameter 3), and the data lengths of method signature+method parameters in transaction 1-transaction 3 are d1, d2 and d3, respectively, the format of the batch transaction is: bulk transaction smart contract address: an ID; batch transaction parameters: id1; d1; parameter 1; id2; d2; parameter 2; id3; d3; parameter 3. It should be appreciated that in forming a batch transaction, the strings in the batch transaction parameters may be directly spliced end to end without the need for separators or the like. And considering that the method signature and the method parameter in the transaction are not fixed in length, it is necessary to calculate the data length of the method signature and the method parameter of each transaction in advance and add the data length of the fixed length to the batch transaction parameters so as to accurately extract the contract address and the method signature and the method parameter of each transaction.

Therefore, in the embodiment of the specification, a batch of transactions can be created by splicing the data structures of the transactions, so that the transactions do not need to be signed respectively, only the batch of transactions are signed, and the complexity of signature processing is reduced.

Step 204: after verification is passed and consensus packaging is carried out, other blockchain nodes acquire contract addresses through analyzing the batch transaction, and call the batch transaction intelligent contracts to verify each transaction corresponding to the batch transaction parameters based on the contract addresses; if the verification is successful, step 206 is performed, otherwise the process ends.

When the blockchain node receives batch contract transactions, the blockchain node has no difference with common transactions when verifying the transactions in a transaction pool, and the signature and the transaction format of the blockchain node are verified to be correct. After the consensus packaging transaction, the transaction execution modules of other blockchain nodes are also indistinguishable from the common transaction in processing, and all the transactions are handed to an executor for processing. In the scheme of the application, only the signature of batch transactions is required to be checked, and each transaction is not required to be checked, so that the workload of checking the signature is reduced, and the verification processing efficiency is greatly improved.

Then, other block chain link points analyze the batch transaction to obtain contract addresses; a method in the bulk transaction intelligent contract is then invoked based on the contract address to effect processing of the bulk transaction. Specifically, calling the batch transaction intelligent contract based on the contract address to acquire a subcontract address and a data length of a first transaction from batch transaction parameters, and acquiring method data of the first transaction according to the acquired data length; sequentially acquiring subcontract addresses and method data of each subsequent transaction according to the mode; if the subcontract address and the method data of all the transactions are successfully acquired, determining that the format verification of each transaction is correct; otherwise, processing the error report and terminating the batch transaction.

Still taking the above-mentioned batch transaction as an example, after receiving the batch transaction, according to the format of the batch transaction: bulk transaction smart contract address: an ID; batch transaction parameters: id1; d1; parameter 1; id2; d2; parameter 2; id3; d3; and 3, extracting the ID from the parameters, calling a method in the batch transaction intelligent contract corresponding to the ID based on the ID, and sequentially verifying the format of each transaction from the batch transaction parameters, namely accurately extracting each transaction. Because the target contract address is of a fixed length, the subcontract address of the first transaction can be extracted from the batch transaction parameters according to the set fixed length, and meanwhile, one parameter, namely the data length, is also of a fixed length, so that the data length (parameter) of the first transaction can be extracted from the batch transaction parameters according to the set length value of the data length; then, extracting a method signature and a method parameter of the matching length from the batch transaction parameters according to the extracted data length; in this way, a data structure of the first transaction is obtained. And extracting the data structure of each transaction from the remaining parameters in the manner described above. If the data structures of all the transactions are successfully obtained, the verification of the data structures of the batch transactions can be determined to be correct, otherwise, error reporting processing is needed, and the batch transactions are terminated.

Step 206: the other block link points call corresponding transaction sub-contracts to process each transaction based on the transaction sub-contract address of the transaction.

When each transaction is processed, the address of the transaction subcontracting is used, the method signature and the method parameters are used for processing the subcontracting, and Gas fees and the like required by the transaction are transmitted. Gas, among other things, may be understood as the computational and/or memory resources required to support the execution of transactions. And processing all the transactions in a sequential processing mode, and finally finishing batch transaction processing when all the transactions are processed, and recording that all the transaction processing is finished in an event mode.

An implementable solution, after the at least one blockchain node obtains a contract address by parsing the bulk transaction and before invoking the bulk transaction intelligent contract to verify each transaction corresponding to the bulk transaction parameter based on the contract address, the method further comprises:

Judging whether the batch transactions carry method marks representing the dependency relationship between the transactions or not; if the transaction is carried, the at least one blockchain node invokes a first transaction method matched with the method mark from the batch transaction intelligent contract, invokes a corresponding transaction sub-contract to process the transaction based on the transaction sub-contract address of each transaction, and terminates the batch transaction when any transaction fails to process, rolls back transaction data, namely rolls back the processing state of each transaction before; otherwise, the at least one blockchain node calls a second transaction method from the batch transaction intelligent contracts, calls a corresponding transaction sub-contract based on the transaction sub-contract address of each transaction to process the transaction, and skips the transaction to continue to execute the next transaction when any transaction fails to process.

That is, two sets of methods are pre-deployed in the bulk transaction smart contract, one set is executed for a bulk transaction composed of a plurality of transactions having a dependency relationship, and the other set is executed for a bulk transaction composed of a plurality of transactions having no dependency relationship. The multiple transactions with the dependency relationship may refer to that the multiple transactions have time sequence, cause and effect or state dependency relationship, and may be embodied on specific transaction association, which in the embodiment of the present specification mainly refers to that the multiple transactions have time sequence dependency relationship.

After the block link point obtains the contract address based on the received batch transaction, the batch transaction smart contract to be invoked is determined. And judging whether a method mark representing the dependency relationship between the transactions is carried in the batch transactions, if so, calling a first transaction method corresponding to the method mark to process the batch transactions, and immediately terminating the batch transactions and rolling back when the transaction processing fails. Otherwise, the second transaction method can be called to process the batch of transactions, and when the transaction processing fails, the next transaction is skipped to continue to be executed. Specifically, the batch transaction can carry a method mark 1 which represents that the transactions have a dependency relationship, or carry a method mark 0 which represents that the transactions have no dependency relationship. For another example, the batch transaction may carry method tags 1 that characterize the dependency between transactions, or the batch transaction may not carry any method tags. The first transaction method can correspond to the method mark 1, and the second transaction method can correspond to the method mark 0 or no mark.

Further, when the second transaction method is called to process each transaction and the transaction processing fails aiming at the batch transaction without the dependency relationship, the transaction with processing failure can be recorded in a contract event mode; or in the transaction processing process, when the calculation and/or storage resources required by supporting the transaction execution are insufficient, the batch transaction is terminated, and the transaction which is successfully processed is recorded in the batch transaction intelligent contract in a contract event mode. In this way, the inquiry can be facilitated, so that the outstanding transactions can be reprocessed only next time, and all transactions are prevented from being reprocessed, thereby saving processing resources and cost.

When the first transaction method is called to process each transaction and the situation that the transaction processing fails/calculation and/or storage resources needed by supporting the transaction execution are insufficient is caused, the batch transaction is terminated, the processing states of all sub-transactions in the current batch transaction are not submitted to the blockchain state, and only the transaction processing commission is deducted.

Optionally, after the batch transaction is finished, the target user terminal may further obtain a processing result of the batch transaction by monitoring a contract event on the batch transaction smart contract; and/or; the target user terminal can also acquire the processing result of the corresponding transaction by monitoring the contract-on event of the sub-contract corresponding to each transaction. That is, after each transaction is completed, the processing result is recorded on the sub-contract corresponding to the transaction in a contract time manner, so that the subsequent target user terminal can remotely monitor to acquire the processing result. Similarly, all transaction completion conditions can be recorded on the batch transaction intelligent contract in a contract event mode: and (3) all successful processing, partial failure processing and the like so that the subsequent target user terminal can remotely monitor and acquire the processing result.

According to the embodiment of the specification, the target user terminal can use the address of the intelligent contract for batch transaction as the contract address, and splice transaction parameters of a plurality of transactions to be submitted to obtain batch transaction parameters, so that the plurality of transactions are combined and created into one batch transaction; after signing the batch transaction, sending the batch transaction signature to a blockchain node for verification, after the verification passes and the consensus packaging is carried out, calling a batch transaction intelligent contract corresponding to a contract address to analyze batch transaction parameters so as to sequentially carry out format verification on each transaction, and if all the verification is correct, sequentially calling a transaction sub-contract corresponding to a transaction sub-contract address of each transaction to process the corresponding transaction. Therefore, when the transaction is processed, only one signature and verification are needed, the volume of data of batch transaction is smaller than that of a plurality of transaction data, the processing capacity of block chain tension is greatly relieved, and the transaction processing efficiency is improved. In addition, the batch transaction scheme can save the transaction cost of the user for the situation of operating according to the transaction times. And meanwhile, the batch transaction mode can also enable a user to conveniently process a plurality of transactions with order dependence or transaction requirements. The batch transaction is not different from the original common transaction, the blockchain does not need to be additionally transformed, and the batch transaction can be realized only by adding the intelligent contract of the batch transaction.
