Data interaction system based on block chain, and relay server

Abstract

The invention provides an application system based on a block chain. The system comprises one or more clients, a block chain full-node network, and one or more relay servers, wherein the block chain full-node network consists of one or more block chain full-nodes, which are in network connection with each other, the one or more relay servers are connected with at least one block chain full-node inthe block chain full-node network and are used for maintaining data cache and providing service for the data; the one or more relay servers are provided by one or more relay service providers; the one or more clients further comprise a relay switch, so that a user can conveniently select to open or close the relay service, when the user selects to close the relay service, the client directly performs data interaction with the block chain full-node network, and when the user selects to open the relay service, the client performs data interaction with the block chain full-node network through the relay server. The system can reduce the cost and risk, trace the data modification, and meanwhile can realize an automatic push function through the relay server, thereby improving the data processing efficiency.

Description

Technical field [0001] The present invention relates to the technical field of data processing, in particular to a data interaction system and a relay server based on a blockchain. Background technique [0002] Although the traditional centralized data interaction system is a typical successful case of Internet technology application, it still has the following drawbacks: [0003] 1. Security risks [0004] In a centralized system, users' personal information, account information, credit information, and transaction information are all stored in the centralized platform. This information may be stolen or sold to others for accurate advertising or even more harmful abuse. In addition, as a transaction intermediary, the platform will also take care of the user's funds, so there is a risk of the platform embezzling funds. In a more extreme case, when the platform encounters a hacker attack, the risk of funds being stolen will be greater. [0005] 2. Oligopoly and monopoly [0006] After...

AI Technical Summary

Problems solved by technology

Since the centralized platform has a large amount of resources, it is easy to set different thresholds for different users, so there is a risk of unfair competition

At the same time, the cost of competition is also controlled by the centralized platform, which eventually leads to an increase in transaction costs

[0007] 4. Data is easy to be tampered with

[0008] In the centralized data interaction system, since the data is only stored in the centralized database, it is easy to be tampered with

For example, the platform cheats to modify the ratings of merchants or forge transaction data, etc., which will cause risks to the authenticity and fairness of the system.
