Method and system for storing massive data based on block chain

摘要

A blockchain-based mass data storage method and system is disclosed. In the method for storing large-capacity data according to the present invention, when a computer interworking with a P2P overlay network and operating as a node of a blockchain network is requested to register target data from a user terminal connected to the blockchain network, a session between the node and the user terminal is established. Setting up; Receiving target data from a user terminal through a session and storing it in a local storage of the node; Performing an electronic signature on the target data through a blockchain network; Storing the digitally signed target data in an arbitrary location on the P2P overlay network, and generating a URI (Uniform Resource Identifier) including information on the location and a hash value used for the digital signature; Generating a transaction for newly registering target data in the blockchain network, but controlling the URI to be stored in the block of the blockchain network; And instructing to create a copy of the target data by passing the URI to another node of the blockchain network.
