Data sharing system based on block chain

Abstract

The invention relates to a data sharing system based on a block chain. The system comprises the block chain, a processor and a memory storing a computer program. The block chain comprises a data storage unit which represents n data storage units, Di represents the ith data storage unit and is used for storing the ith event information, i represents an event type id, i=1, 2, 3...n, an ith data table is stored in Di, and the fields of the ith data table comprise a node id, a content id, content data and a content state value. According to the invention, the data sharing efficiency and accuracy are improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a blockchain-based data sharing system. Background technique [0002] Data sharing is usually implemented collaboratively by multiple servers, and existing data sharing systems are usually processed in a centralized manner. For example, the server at the first level sends the original data to the server at the second level, the server at the second level integrates the received data and sends it to the server at the third level, and the servers at the third level send the integrated The data is sent to the fourth-level server until the data finally reaches the central server, which makes the information routing transmission distance long, the transmission level is multiple, the data transmission efficiency is low, the data sharing is not real-time, and the efficiency is low, and the data is integrated in the middle-level server When the event occurs, data errors may oc...

For example, the server at the first level sends the original data to the server at the second level, the server at the second level integrates the received data and sends it to the server at the third level, and the servers at the third level send the integrated The data is sent to the fourth-level server until the data finally reaches the central server, which makes the information routing transmission distance long, the transmission level is multiple, the data transmission efficiency is low, the data sharing is not real-time, and the efficiency is low, and the data is integrated in the middle-level server When the event occurs, data errors may occur, resulting in low accuracy of the data finally reaching the central server, resulting in low accuracy of data sharing. In addition, when different servers send different data for the same event, there will be data conflicts. It is difficult to judge which data is more accurate
