Embodiment 1

[0026] figure 1 It is a schematic flow diagram of a blockchain-based data storage method provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of storing data, and the method can be implemented by a blockchain-based data storage device to execute. Such as figure 1 As shown, the method specifically includes the following steps:

[0027] Step 110: Divide the target data into at least one piece of data according to a preset piece control strategy, and store the piece of data in a database server; wherein, one database server stores one piece of data.

[0028] Wherein, the complete data table in the database can be used as the target data, and the data table is divided according to a preset fragmentation control strategy. The fragmentation control strategy is set in advance, and the fragmentation control strategy can be to divide the data table into a preset number of behavior units. For example, if the target data is a data table with si...

Abstract

The embodiment of the invention discloses a data storage method and device based on a block chain, equipment and a storage medium. The method comprises the following steps: dividing target data into at least one piece of fragmented data according to a preset fragmentation control strategy, and storing the fragmented data into a database server; wherein one database server stores one piece of fragmented data; according to a preset Hash algorithm, performing Hash calculation on the fragmented data in the database server to obtain a first Hash value of the fragmented data; obtaining a second hash value of the target data according to the first hash value of the fragmented data; and storing the first hash value in a block body, and storing the second hash value in a block head to complete data storage of the block chain. The pressure of the database server is relieved, and the safety of data storage is improved.

Description

technical field [0001] Embodiments of the present invention relate to computer technology, and in particular to a blockchain-based data storage method, device, device, and storage medium. Background technique [0002] As the amount of data increases, the data takes up a lot of space when it is stored, the pressure on the database server is high, and the data is easily lost or omitted. Therefore, people's requirements for data storage are getting higher and higher. [0003] Database sharding is a scale-out approach to database architecture that separates a larger database into smaller, faster, and more manageable partitions. A database can be distributed among multiple database server instances, and each database server instance can hold database fragments. However, databases and database shards are vulnerable to hacking or forgery, and the authenticity, consistency, and security of data cannot be guaranteed. Contents of the invention [0004] Embodiments of the present i...
