Abstract

The invention relates to the field of block storage systems. The invention provides a data fragment storage method and device, a terminal and a readable storage medium. The method comprises the following steps: when receiving to-be-stored data, calculating a hash value of the to-be-stored data, comparing the hash value of the to-be-stored data with the hash value of the data storage node in the blockchain; and determining a first preset number of target storage nodes according to a comparison result, then splitting the to-be-stored data into a second preset number of sub-data, and respectivelystoring each sub-data into each target storage node based on a preset storage sequence. According to the method and the device, the data is split into the preset number of sub-data, the sub-data is dispersedly stored in the plurality of nodes, and the data storage allocation condition on the block chain is managed through the data storage record table, so that the effective utilization of the whole block chain network for storage is improved while the repeated redundancy of the block chain network is reduced.

Description

technical field [0001] The present invention relates to the field of block storage systems, and in particular to a method, device, terminal and readable storage medium for data slice storage. Background technique [0002] The current blockchain or consortium chain solution uses a single-point full storage solution, and each node stores complete blockchain data. This realizes data distribution, so that any node failure will not affect the entire network, and any node can completely verify the data of the entire blockchain history. But it also brings another problem. With the continuous increase of blockchain historical data, the single-point storage capacity will also increase. At the same time, the more nodes are added, the redundant storage will also increase linearly, which is invisible. In this way, the effective utilization of storage by the entire blockchain network is reduced. Contents of the invention [0003] The main purpose of the present invention is to provid...
