Embodiment Construction

[0059] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0060] refer to figure 1 , an embodiment of the present application provides a fabric alliance chain task execution method, the execution method includes:

[0061] S1: Receive a task execution request, where the execution request carries task information;

[0062] S2: Using the snapshot technology to back up the first task data corresponding to the task information, to obtain a snapshot of the first task data;

[0063] S3: Execute the smart contract of the task according to the snapshot of the first task data, and obtain the signed task;

[0064] S4: Pack the signature ...

Abstract

The invention provides a task execution method and device for a fabric alliance chain, computer equipment and a computer readable storage medium, and relates to the field of data processing. The method includes the following steps: receiving an execution request for a task; backing up first task data corresponding to task information by using a snapshot technology to obtain a first task data snapshot; executing a smart contract according to the first task data snapshot to obtain a signature task; packaging the signature task to obtain a task block; judging whether the task block is legal or not; and if yes, storing the task block. According to the invention, snapshot is carried out on current task related data in an original database, therefore, when the task data is read and written subsequently, operations such as smart contracts can be directly carried out through the data in the snapshot, a read-write lock does not need to be used for the data in the original database, reading andwriting of other task data are not influenced while the consistency of the task data is ensured, multi-thread operation is realized, and the concurrency performance is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a fabric alliance chain task execution method, device and computer equipment. Background technique [0002] Blockchain is generally understood as a distributed ledger, and its essence is also a distributed database. In the existing blockchain architecture, all data is stored in leveldb in the form of key-value pairs (LevelDB is Google's open source persistent KV stand-alone database). In order to ensure data consistency and fault tolerance, leveldb uses read-write locks for reading and writing data, so that nodes cannot execute endorsement and storage blocks at the same time, and become a fabric alliance chain to achieve high concurrency through multi-threaded execution tasks a bottleneck. Contents of the invention [0003] The main purpose of this application is to provide a solution to the disadvantages of the existing fabric alliance chain that cannot...
