Problems solved by technology

[0002] Most of the traditional electronic data exchange technologies use centralized data exchange systems. The centers are all large servers that require strict maintenance. The security risk of the central server being attacked is high. Once the central server is unavailable, the entire system will be unavailable. Centralized servers The load is very heavy, and the speed of data exchange is often not guaranteed

Abstract

The invention relates to an electronic data exchange method based on a block chain, which comprises a data storage subsystem, a block chain node and an external data interface subsystem and is used for realizing electronic data reading and electronic data writing based on the block chain. And the external data interface subsystem calls a block chain node, realizes electronic data reading of data on the data storage subsystem by using a method based on ASCII code displacement, ensures reading integrity and non-tampering performance, and realizes electronic data writing by using a broadcast mechanism of block chain consistency.

Description

technical field [0001] The invention belongs to the field of computers and provides a block chain-based electronic data exchange method. Background technique [0002] Most of the traditional electronic data exchange technologies use centralized data exchange systems. The centers are all large servers that require strict maintenance. The security risk of the central server being attacked is high. Once the central server is unavailable, the entire system will be unavailable. Centralized servers The load is very heavy, and the speed of data exchange is often not guaranteed. There is an urgent need for a method that utilizes the decentralization and non-tamperable characteristics of blockchain technology to effectively ensure that the acquired electronic data is not tampered with and verify the integrity of the data. Contents of the invention [0003] In view of this, in order to achieve the effect of the above solution, the present invention provides a blockchain-based elect...
