Embodiment 1

[0040] Such as figure 1 As shown, this embodiment provides a blockchain-based data distributed storage and data retrieval method, in this embodiment, it involves a data collection module, a data storage module, a user management module, a data consensus module, and a database module and a target retrieval module; wherein, the data collection module is used to obtain the data to be transmitted of any distributed node in one-to-one correspondence, and each node connected to the blockchain uses the data collection module to obtain the data to be uploaded. The data storage module is connected with the data collection module, and is used to obtain the data to be transmitted collected by the data collection module, and adopts the Zcash mining algorithm to store the data to be transmitted. Here, the purpose of using the Zcash mining algorithm is to improve the retrieval efficiency of the target retrieval module and shorten the time for data retrieval. The user management module of t...

Abstract

The invention discloses a block-chain-based data distributed storage and data retrieval method, which comprises the following steps that: any user uses a user management module to lift an access application, and verifies and configures a corresponding user account; a data collection module is used for collecting to-be-transmitted data, and the to-be-transmitted data is stored in a data storage module through the Zcash mining algorithm in combination with the identity information of a user; a data consensus module encrypts the to-be-transmitted data according to the identity information, stores the to-be-transmitted data into a block chain according to a time sequence, and affixes a corresponding timestamp; any user acquires data stored in the block chain by using a target retrieval module according to the user account number to which the user belongs; and a database module of any node regularly incrementally updates the contents of the database and the block chain. Through the scheme, the security level of data access can be ensured, and the data retrieval time can be shortened, and the block-chain-based data distributed storage and data retrieval method has very high practical value and popularization value in the technical field of block chains.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to methods for distributed data storage and data retrieval based on block chains. Background technique [0002] Traditional data storage and retrieval are based on service centers. Due to the continuous increase of network data, data storage and retrieval take a long time. In addition, there are many security risks in the existing data storage and data retrieval. [0003] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The consensus mechanism is to establish trust between different nodes in the blockchain. Mathematical algorithm for obtaining equity. Contents of the invention [0004] In view of the above problems, the object of the present invention is to provide a blockchain-based data distributed storage and data retrieval method, the technical sc...
