Embodiment Construction

[0042] The core of this application is to provide a blockchain-based data transaction method and system, which uses the decentralized characteristics of the blockchain to solve the defects of centralized storage. Each user is a node in the blockchain network. By deploying the smart transaction contract to the blockchain network, it is hoped to establish a data transaction channel between the data producer and the data buyer. For data storage, a distributed storage network with lower storage cost and higher security performance is selected to enable transaction data Storing and generating a data index with a very small amount of data in the form of ciphertext to locate the corresponding ciphertext is different from directly saving the data to the blockchain network, which can effectively reduce the cost of data storage. At the same time, the blockchain network will save all transaction records and synchronize them to all nodes, which greatly avoids the possibility of tampering, a...

Abstract

The present application discloses a blockchain-based data transaction method, which utilizes the decentralization feature of the blockchain to solve the defect of centralized storage. Each user is a node in the blockchain network, and the intelligent transaction contract is deployed to the blockchain network to establish a data transaction channel between the data producer and the data purchaser.The data storage uses a distributed storage network with lower storage cost and higher security performance, the tradable data is stored in the form of cipher texts, and data indexes with a very smallamount of data are generated to locate the corresponding cipher texts, which is different from directly saving the data to the blockchain network, thereby effectively reducing the data storage cost.At the same time, the blockchain network saves all transaction records and synchronizes them to all nodes, greatly avoiding the possibility of tampering and making all transaction records public and transparent. The application also discloses a blockchain-based data transaction system, which has the above beneficial effects.

Description

Technical field [0001] This application relates to the field of blockchain technology, and in particular to a data transaction method and system based on blockchain. Background technique [0002] In the era of big data, no matter for individuals or enterprises, data has immeasurable value, so the application of data transaction industry is born. When users use the services provided by the service (application) provider, they also continuously generate personal data, which has extremely high commercial value. [0003] As the data generator that generates this personal data, it should be able to obtain the right to trade this part of the data. In actual circumstances, due to the inherent advantages of the service provider’s centralized data storage method, it is easy to obtain the right to deal with this part of the data. The right to process personal data according to personal wishes, and users lose the ability to collect and process personal data, resulting in the current service ...
