AI Technical Summary

Technical Problem

Blockchain nodes need to store a large amount of historical data, resulting in increased hard disk space requirements, and existing technology relies on the reliability of the network and other nodes for data verification, increasing network interactions and costs.

Method used

By archiving, packaging and sharding storage of historical block data, and using logical distance to select nodes for data storage and backup, the number of data backups is reduced, and hard disk requirements and network interactions are saved.

Benefits of technology

It realizes the efficient use of nodes in the blockchain network, reduces the burden on the hard disk, flexibly responds to node downtime and the addition of new nodes, and ensures data stability and network efficiency.

Abstract

The present invention belongs to the field of computer technology, and in particular relates to a distributed storage method, device, and storage medium for blockchain data. Distributed storage and a dynamic balance backup strategy eliminate the need for each node to store all block data, thereby improving the utilization efficiency of nodes in the blockchain network, reducing the node's hard disk requirements, and saving node deployment costs. Furthermore, the method can flexibly respond to node downtime and exit and new node addition. Due to periodic statistical backup, the backup of archived data is in a dynamic balance, so that the downtime of existing nodes will not affect the storage of original archived data, and the addition of new nodes will not affect the location query of original data. Furthermore, data can be quickly acquired, ensuring the stability of the blockchain.
