A gateway information sharing query method and system based on a block chain

Abstract

The invention provides a gateway information sharing query method and system based on a block chain, and belongs to the technical field of block chains. The method includes: generating raw data; Writing the plaintext data of the original data into a service system database; Installing and deploying a data gateway, and carrying out node initialization; enabling the data gateway to perform data conversion processing on the plaintext data; Transmitting the plaintext data and storing the plaintext data in a local private database; And unselectively broadcasting the hash value of the plaintext datato the related nodes on the chain through a consensus mechanism in a multilateral classification account design mode. The invention also provides a block chain-based gateway information sharing querysystem, which adopts a localized data gateway and a private database to store the plaintext data and the abstract value separately. According to the method and the device, the privacy of the user canbe effectively protected, the problem of congestion caused by continuous increase of the data storage amount of the whole shared network is effectively avoided, and the processing efficiency and theperformance are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a block chain-based gateway information sharing query method and system. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order. As the underlying technology of various digital currencies such as Bitcoin, blockchain is similar to a database ledger that records all Due to its safe and convenient features, blockchain technology has gradually been valued and adopted by many industries such as science and technology, finance, and commerce. However, the blockchain technology in the existing technology is still in practical application. There are many technical problems and drawbacks, mainly reflected in: [0004] On the one hand, in the traditional blockcha...

Problems solved by technology

[0004] On the one hand, in the traditional blockchain accounting method, in order to ensure that the distributed ledger and data cannot be tampered with, each time a participating node generates a transaction record or uploads plaintext data, each node needs to update and save a copy of the information record , in other words, the participating nodes need to store the transaction records and plaintext data copies of all other nodes, which will inevitably lead to the inability to effectively guarantee the privacy of users. Processing performance and efficiency gradually deteriorate

[0005] On the other hand, the process for users to transmit local plaintext data to the blockchain platform or other participating nodes is cumbersome and costly

[0006] It can be seen that the disadvantages of blockchain technology in the existing technology, such as poor user privacy, low platform processing efficiency, cumbersome data transmission, and high operating costs, are becoming technical problems that need to be solved urgently.
