Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] In the following, some nouns appearing in the following detailed description are introduced:

[0051] Smart contract: A contract program that is automatically executed according to specific conditions is an important way for users to interact with the blockchain and use the blockchain to implement business logic. For example, various institutions can access the data storage system through the smart contract on the blockchain deployed in the server to use the data storage and other functions provided by the data storage system.

[0052] Target strategy: The target strategy can be a kind of consensus strategy, which can be used to indicate the necessary conditions to be satisfied in the consensus process in the data storage system...

Abstract

The invention provides a transaction data storage method, device, server and storage medium, and relates to the field of network technology. The present invention only stores the transaction data on multiple trust nodes when there is a demand for transaction data storage, and stores the characteristic value of the transaction data on the block chain instead of storing the transaction data itself on the block chain. When these trust nodes pass the consensus, they store the characteristic value of the transaction data as a block of the blockchain, so that the transaction data can only be stored on a limited number of node devices, and will not spread to every node in the entire blockchain system. Since the node device only stores the characteristic value on the block chain, it limits the viewing of the transaction data by the node device, and can guarantee the privacy of the transaction data while ensuring the data security.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a transaction data storage method, device, server and storage medium. Background technique [0002] With the development of network technology, the Internet can provide more and more services. Correspondingly, in order to achieve data security and prevent data from being tampered with, in the process of business processing, it will involve how to securely store transaction data. . [0003] The current data storage method can be based on the blockchain system. The blockchain system can store transaction data in the blockchain. Since a block in the blockchain not only stores the transaction data and block characteristics of the block value, and also stores the block feature value of the previous block. Therefore, based on such data association, it is guaranteed that the data will not be tampered with, and even if any data is tampered with, it can be traced back. [0004] The cur...
