Moreover, due to the various types of data in each client, when the blockchain technology is used, the corresponding data is stored in the blockchain database of each client at the same time. However, because the data of the enterprise has different permissions for different clients, Therefore, it is hoped to provide a reasonable encryption method instead of a simple equal-privilege encryption method, which will inevitably affect the security of data

Abstract
The invention discloses a system and a method for realizing data query by applying an account book of a blockchain, and relates to the technical field of block chains. By constructing a blockchain account book architecture, reliability, comprehensiveness, safety and accuracy of a novel family account book of the blockchain are further improved, so that the reform and development of the traditionalaccount book are promoted. Various big data algorithm models are integrated into the blockchain account book architecture to realize data calculation and processing, so that simple processing of various complex data is realized, the information latitude of big data is reduced, and data query is facilitated. Encryption calculation after data processing is achieved through an encryption unit, and safety performance of data is improved. A modular blockchain solution supporting platform based on Hyperleder Fabric is used, a blockchain data calculation, sharing and transmission platform is provided, and data processing, calculation and query are realized; and data packaging and processing are realized through a password signature module and a timestamp module.
Description
technical field [0001] The present invention relates to the technical field of block chain, and more specifically relates to a system and method for realizing data query by applying block chain ledger. Background technique [0002] With the development of blockchain technology, blockchain, as an enabling technology for value transmission, is gradually building a decentralized, self-organizing, and data-sharing trusted infrastructure, reshaping existing Internet applications and traditional industries. For blockchain infrastructure, secure encryption is the core function to maintain the security of the entire system. Therefore, as a decentralized distributed ledger technology, the blockchain can provide a new technical approach for data release by using its decentralization, data tamper-proof and traceable properties. [0003] Digital assets refer to non-monetary assets owned or controlled by enterprises or individuals that exist in the form of electronic data, are held in d...
