Abstract

The invention provides a blockchain data registration method and device, and the method comprises the steps: receiving a registration transaction request sent by a client, the registration transactionrequest comprising user account information and user data abstract information; calling an oracle smart contract, and determining whether user data corresponding to the user data abstract informationis available or not; and under the condition of determining that the user data corresponding to the user data abstract information is available, calling a data registration smart contract, and registering a mapping relationship between the user account information and the user data abstract information. According to the method, the mapping relationship between the user account information and theuser data abstract information can be sent to the blockchain for evidence storage, so that the user privacy can be effectively protected.

Description

technical field [0001] This application relates to the technical field of blockchain, in particular to a blockchain data registration method and device. Background technique [0002] Most of the existing data storage schemes are centralized. A single third party provides the file storage service system and provides the corresponding registration management system and client at the same time. Users upload files to the file registration management system through the client. , the management system encrypts user files and then stores them in the storage service system. [0003] However, once a technical disaster occurs to the service provider in the centralized method, the stored files will be completely lost and cannot be retrieved. The traditional solution is to make multiple duplicate backups of the same data through multiple master-slave services, but This method will increase the cost of operation and maintenance. On the other hand, for users, the processing of their own...
