Background
The intelligent contract virtual machine execution of the current blockchain is single-threaded, and all transactions are executed in the same virtual machine according to a queue, so that the transactions can be ensured to be executed according to the sequence. However, in some scenarios (e.g., privacy transactions), a misordering of transaction execution may result in failure of all subsequent transactions, and thus in-order execution is very important. If parallel processing is required, the existing solution is to enable multiple branches, each processing a different transaction on a different branch.
The existing solutions have mainly the following drawbacks: the connection between the branches is not tight enough, and the data intercommunication between the branches needs to be verified, so that a large amount of calculation force can be digested. That is, a disadvantage of this solution is the high cost of data interworking between branches.

Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be understood that the terms "comprises" and "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
Referring to fig. 1 and 2, the method for processing an intelligent contract transaction provided in the embodiment of the application mainly includes:
s101, predefining a first virtual machine process, a second virtual machine process and a front-end server.
Specifically, two different smart contract virtual machine processes A and B are predefined, and a pre-server is predefined that can identify whether a smart contract transaction has an existing order.
S102, predefining a first network line and a second network line.
Specifically, two different network lines 1 and 2 are predefined and mapped to two virtual machine processes a and B, respectively.
S103, receiving a plurality of intelligent contract transactions to be processed.
S104, processing a plurality of intelligent contract transactions to be processed by adopting a predefined front-end server to obtain a first queue and a second queue.
The first queue has a sequence, and the second queue does not have a sequence.
Specifically, a front-end server is adopted to identify a plurality of intelligent contract transactions to be processed, the intelligent contract transactions are placed in a first queue with a sequence, and the intelligent contract transactions are placed in a second queue without the sequence.
For example, if the front end server identifies that there are 10 transactions in order, and there are 10 transactions in no existing order, then 10 transactions are placed in the first queue and 10 transactions are placed in the second queue.
It should be noted that, in addition to the above example case, the following cases may also exist:
if there are 3 transactions in sequence and 17 transactions in no sequence, the speed is affected by placing 17 queues in one queue, and after 3 queues are placed, 7 non-sequential filling is carried out in the queue, so that 10 queues are used for balancing.
S105, the first queue and the second queue are sent to a blockchain, so that the blockchain executes the first queue by adopting a predefined first virtual machine process and executes the second queue by adopting a predefined second virtual machine process.
Specifically, transactions of different queues are sent to the blockchain over network lines 1 and 2, respectively. The block chain receives the transactions of different lines, identifies different network lines, and executes on virtual machine processes corresponding to the network lines respectively. The two do not affect each other. That is, the transaction from line 1 is performed by virtual machine A and the transaction from line 2 is performed by virtual machine B.
S106, receiving the processing result sent by the block chain.
The processing results refer to execution results of the first virtual machine process and the second virtual machine process on the first queue and the second queue.
And S107, storing the processing result in the same block chain.
From the above description, it can be seen that, by implementing the intelligent contract transaction processing method of the embodiment of the application, different intelligent contract virtual machine branches are started on the same chain, so that the performance is improved while the data is ensured to be still on the same chain, and the cost of mutual authentication between the branches is reduced.
It should be noted that, in the above-described technical solution, the front-end system is used to isolate the querier from the chains, and the manner of accessing the chains with different rights by the querier can be changed. Therefore, the trust degree of the inquirer on the data can be improved, and the situation that the permission isolation is invalid or the data is leaked due to improper setting or problems of the front-end system can be prevented.
