Problems solved by technology

For the scenario of massive data storage, the demand for storage is very high, and in the traditional blockchain network, the data is stored through a single disk. Due to the limitation of the upper limit of the single storage, the current blockchain network cannot cope with the massive data storage.

Abstract

The embodiment of the invention provides a data storage method and device based on a blockchain network. The data storage method and device are used for improving the data storage capacity of the blockchain network. The method comprises the steps of obtaining a data storage request sent by a data owner, wherein the data storage request comprises to-be-stored data; performing consensus processing on the to-be-stored data; after the consensus of the to-be-stored data is reached, sending the to-be-stored data to a first storage group in the blockchain network so as to store the to-be-stored data in each storage node in the first storage group. Therefore, the consensus function and the storage function in the block chain network are decoupled from the same block chain node, the consensus node is liberated from the aspect of the storage function, and the reliable storage of the data is realized through each storage node in the special storage group, so the problem that the single-machine storage space of the consensus node is limited is solved, and the storage capability of the blockchain network is improved.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a data storage method and device based on a blockchain network. Background technique [0002] Blockchain is a composite technology comprehensively implemented by using cryptography methods, computer networks and distributed storage technologies. Blockchain provides a distributed data sharing model with decentralization (point-to-point network communication), impossible Tampering, leaving traces throughout the process, collective maintenance, openness and transparency, etc. Based on these characteristics of the blockchain, users can store data on the blockchain to share data through the blockchain. User data generally involves the user's own privacy, so it is necessary to effectively protect the data stored on the blockchain to ensure data security. [0003] Although the traditional blockchain network is decentralized and includes many consensus nodes, each consensu...
