BLOCKCHAIN-BASED DATA STORAGE METHOD, SYSTEM AND APPARATUS

摘要

Disclosed are a blockchain-based data storage method, system and apparatus, which relate to the technical field of blockchains. The specific implementation solution is: in response to the reception of a matching result sent by a computing node, acquiring data to be stored of a requesting node, wherein the matching result is obtained by means of performing, on the basis of node information, resource balanced matching on a data storage request, and the node information is obtained from a first blockchain on the basis of the computing node; initiating a transaction according to the data to be stored of the requesting node, and generating transaction data corresponding to the data to be stored of the requesting node; verifying the transaction according to metadata; receiving a result indicating that verification is passed and sent by the requesting node; and in response to transaction verification being passed and receiving the result indicating that the verification is passed and sent by the requesting node, storing the transaction data in a second blockchain. Provided is a dual-public-blockchain based secure storage solution, which improves the security of remote data storage in a blockchain network.
