Embodiment 1

[0021] Such as figure 1 As shown, the present invention discloses a blockchain data storage method, the blockchain network is divided into consensus nodes and data storage nodes; the consensus node includes a central server for storing and processing the Storage request; multiple sub-servers are used to receive data storage requests from users; storage nodes include blockchain information storage area, blockchain file temporary storage area, and blockchain local storage area; the storage method is as follows:

[0022] The user sends the data storage request to the corresponding sub-server, and uploads the data to the temporary storage area of ​​the blockchain file at the same time. After the sub-server verifies the identity information, it will feed back the request to the central server. The central server will mark the request and classify it. The information is stored in the blockchain information storage area and fed back to the sub-server. The sub-server marks the files i...

Abstract

The invention relates to a block chain data storage method and device. The block chain network is divided into consensus nodes and data storage nodes; the consensus node comprises a central server and is used for storing and processing storage requests sent by all levels of sub-servers; the plurality of sub-servers are used for receiving data storage requests of all users; according to the invention, after a user applies for data storage, the data abstract is extracted, the data file is cached in the block chain file temporary storage area, and the data file is stored in the block chain local storage area after being marked and positioned through the central server and the sub-server, so that the storage pressure in the whole block chain is reduced, and the block chain local storage areas are connected through the network; and the data summary information and the user information are stored in the block chain information storage area, so that the data storage efficiency and security are improved under the condition that the information quantity is not influenced, and the overall operation efficiency and stability are further improved.

Description

technical field [0001] The invention belongs to the technical field of block chain, and relates to a block chain data storage method and device. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. [0003] Blockchain has the characteristics of decentralization. Through distributed accounting and storage, each node realizes information self-verification, transmission and management. [0004] Blockchain is characterized by openness. The foundation of blockchain technology is open source, and the information of the entire system is highly transparent. [0005] Blockchain has the characteristics of independence. All nodes can automatically and securely verify and exchange data within the system without any human intervention. [0006] Blockchain is characterized by security. As long as you cannot control 51% of all data node...
