Abstract

This application discloses a blockchain-based data storage method, system, and device, which relate to the technical field of blockchain. The specific implementation plan is: in response to receiving the matching result sent by the computing node, obtain the data to be stored by the requesting node, wherein the The matching result is obtained based on the resource balance matching of the data storage request based on node information, the node information is obtained from the first block chain based on the computing node; a transaction is initiated according to the data to be stored of the requesting node, and a transaction with the requesting node is generated The transaction data corresponding to the data to be stored; verify the transaction according to the metadata; receive the verification result sent by the requesting node; respond to the transaction verification and receive the verification result sent by the requesting node, store the transaction data in Second blockchain. This scheme proposes a dual public chain security storage scheme, which improves the security of remote data storage in the blockchain network.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, specifically to the field of block chain technology, and in particular to a data storage method, system and device based on block chain. Background technique [0002] Blockchain is a decentralized chain data structure, which has the characteristics of non-tampering, scalability, and full synchronization. Because the transaction information is transmitted by means of flood broadcasting, it can ensure that the participants of the entire network have full control over all transaction data. consistent view. [0003] In the existing solutions for remote data storage based on the blockchain network, some users who lack local storage space can store their data in blockchain nodes that can provide sufficient storage space. However, due to hacker attacks, information such as the physical location of storage nodes, free disk capacity, and IO traffic may be leaked or tampered ...
