Problems solved by technology

[0004] First, using the erasure code strategy to improve the reliability of data storage has the problem of excessive repair bandwidth overhead. In the process of repairing storage node failures, the calculation complexity is high, and the repair time is long, which cannot meet the storage speed of massive small files. Require
[0005] Second, the method of randomly selecting storage nodes for storage does not consider the performance of each storage node, and cannot effectively use storage nodes to achieve fast and efficient storage

Abstract

The embodiment of the invention discloses a distributed data dynamic storage method based on a block chain and electronic equipment. A specific embodiment of the method comprises the steps of obtaining to-be-stored target data and target metadata; generating a target data block set based on the target data; storing the target data block set in a storage node group; determining a storage relationship set based on the target metadata and the target data block set; storing the storage relationship set in at least one metadata management node; updating the block chain. According to the method, a target data block set is generated after a target data block to be stored is segmented and copied. The multi-copy target data block set ensures the security and restorability of the distributed storagedata. And the target data block set is stored in the storage node group, and the storage node with the highest current comprehensive performance index is dynamically selected for storage according tothe comprehensive performance index of each storage node in the storage node group, so that the storage efficiency and performance are improved.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of blockchain and data storage, and in particular to a blockchain-based distributed data storage method and electronic equipment. Background technique [0002] In today's era, the amount of data generated in the network environment continues to grow rapidly, and distributed storage, as an emerging network online storage technology, has been more and more widely used. Relying on the decentralization and traceability characteristics of blockchain, distributed storage based on blockchain effectively guarantees the confidentiality and credibility of storage and communication, and promotes the development and development of distributed data storage based on blockchain. application. The short video social platforms and e-commerce networks that have been emerging in recent years generate a large number of short videos and pictures every day, and the data storage space for these videos and pictures is ...
