Problems solved by technology

[0004] The main problems of the centralized database are: 1. Managed by a single center, the administrator has too much authority, and there is a possibility of using the data for profit or modifying the data
2. Historical data is easy to be tampered with without being discovered
3. The process of data generation and modification is opaque and not open
The main problems existing in the existing distributed database are: 1. The data synchronization process is relatively complicated

Embodiment Construction

[0049] Below in conjunction with accompanying drawing, preferred technical scheme of the present invention is further elaborated:

[0050]A blockchain-based database system, including: client: through which the user registers a blockchain account with the access server or on the blockchain verification server and obtains a public key and a private key, and secures the account Save; the private key is the undisclosed content, and the public key is the public content. When users submit data, they use the private key to encrypt the data and submit their account public key at the same time; if the data is based on the records of the blockchain database, they also need to submit the previous record information; users and third parties pass user permissions and pass customer The terminal submits a query request to the access server; after the user obtains the data query result, he can directly use the result to read the data, otherwise he needs to perform a data query; after the dat...

Abstract

The invention discloses a blockchain-based database system, comprising a client, an access server and a blockchain verification server. A method of using the blockchain-based database system comprises the steps of 1, registering a blockchain account on the blockchain verification server through the client, or registering, by the blockchain verification server itself, the blockchain account on the blockchain verification server, and acquiring a public key and a private key; 2, writing, by a user, data into the access server through the client; 3, transmitting, by the access server, a request to the blockchain verification server to perform data co-recognition; 4, submitting, by the user, a query request to the access server through the client to perform related query; 5, after the user obtains data query results, directly using, by the user, the results to read data, or otherwise the user having the need to perform data query; after data reading, unlocking the data by the user through his or her own account private key. The problems are solved that data in a central database are insecure and it is difficult for a distributed database to arrive at uniformity and data confidentiality.

Description

technical field [0001] The invention relates to the technical field of database systems, in particular to a blockchain-based database system and a method for using the system. Background technique [0002] A database is a system that organizes, stores and manages data according to its data structure. The database was born in the 1960s. With the development of information technology and the market, especially after the 1990s, the main function of the database is no longer just to store, modify and read data, but to provide users with the required Various tools for data management and analysis. There are many types of databases, ranging from the simplest tables storing various data to large database systems capable of storing massive amounts of data, which have been widely used in various aspects. [0003] In the information society, fully and effectively managing and utilizing various information resources is a prerequisite for scientific research and decision-making manage...
