Abstract

The embodiment of the invention discloses a data storage method and device based on a block chain network, and the method comprises: a first node carrying out the data segmentation of first data, obtaining N data blocks, the first data comprising at least two pieces of backup data of target data, and obtaining the identification of each data block in the N data blocks; and then, the first node distributing each data block in the N data blocks to at least one second node of the block chain network for storage, each second node can store at least one data block in the N data blocks, and the first node and the at least one second node belonging to the same block chain network. The first node may update a block chain ledger in the block chain network based on the identification of each of theN data blocks and the storage path. By adopting the embodiment of the invention, the security of data storage can be improved, and when a single node is attacked, the integrity of the data is not influenced even if the data of the single node is lost.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data storage method and device for a blockchain network. Background technique [0002] Data is recorded in a certain format on the internal or external storage medium of the computer, which is the data storage process. At present, each node in the blockchain network stores complete data according to the block chain structure, and the data stored on each node of the blockchain network is independent and equal in status. When a node in the blockchain network is destroyed due to an attack, the complete data stored on the node will be lost, and the data is not safe. In addition, other nodes cannot obtain the data stored on the node. Lead to data loss and affect the integrity of the data. Contents of the invention [0003] The embodiment of the present application provides a data storage method and device based on a blockchain network, which can improve the secur...
