Abstract

This application discloses a blockchain-based data distributed storage and data acquisition method and device. Wherein, the data distributed storage method based on the block chain includes: the block chain server receives the data sent by the first terminal device, wherein the first terminal device is a node in the block chain; and the block chain The server distributes and stores the data in multiple second terminal devices, wherein the second terminal device is another node in the block chain, and the connection between the first terminal device and the second terminal device They can communicate directly by reusing cell resources. Therefore, after the terminal device configured with the D2D protocol can quickly upload the data to the blockchain server, the blockchain server uses the blockchain technology to distribute and store data in other nodes. At the same time, each node can directly communicate with each other by multiplexing cell resources (D2D protocol), and quickly and efficiently obtain distributed data stored on other nodes.

Description

technical field [0001] The present application relates to the field of data storage, in particular to a blockchain-based distributed data storage and data acquisition method and device. Background technique [0002] 5G network is the fifth-generation mobile communication network, and its peak theoretical transmission speed can reach 10 gigabits per second, which is hundreds of times faster than the transmission speed of 4G network. In addition, terminal devices can directly communicate with each other by multiplexing cell resources (D2D protocol in 5G technology) to provide other terminal devices with required resources, information and other content. Blockchain has the advantages of decentralized distributed data storage, information that cannot be forged and tampered with, automatic timestamping when data is stored, and transaction transparency. Therefore, 5G technology can be combined with blockchain for decentralized data storage, so that large files can be distributed ...
