Block chain-based distributed data storage system

Abstract

The invention relates to the technical field of block chain storage, and discloses a block chain-based distributed data storage system, which comprises a host module, a storage machine module and a calculation module, and is characterized in that the host module is provided with a storage machine and computer registration module, a data consistency maintenance module, a block request generation module and a data request query module; the storage machine module is provided with a data storage module, a data query module and a data self-checking module; the calculation module is provided with a block calculation module; the invention has the advantages that enough network expansibility can be provided, the continuously increasing storage requirement of data can be met, the block generation and data storage efficiency is effectively improved by means of a delegation right and interest proof consensus mechanism, and the data storage security is greatly improved by utilizing the characteristics of the block chain; the problems that a current data storage mode is prone to disorder due to a large amount of data, nodes of data storage are not clear enough, and the safety of data storage is not high are solved.

Description

technical field [0001] The invention relates to the technical field of blockchain storage, in particular to a blockchain-based distributed data storage system. Background technique [0002] Data storage occupies an extremely important position in the Internet era. With the advent of the era of big data, more and more data information is derived. In data storage technology, the disadvantages of hardware storage are becoming more and more prominent, and the storage capacity of hardware storage makes its disadvantages more and more obvious. The technical application of cloud storage also has the disadvantage of relying on servers. The application of a large number of servers will gradually curb the development of Internet technology and bring huge consumption of resources. [0003] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and uses cryptographic methods to associate distributed data with data blocks; blockch...
