Abstract

The invention discloses a file processing method, which comprises the following steps of: encoding a file into a plurality of data blocks by utilizing an erasure code algorithm, and storing the plurality of data blocks in at least two storage nodes which at least comprise storage nodes in a distributed file system; wherein one data block is only stored once; and storing the file index of the file,the respective storage address of each data block in the plurality of data blocks and the hash value related to the file in a block chain network. Therefore, the data redundancy is greatly reduced, higher data reliability is obtained with lower data redundancy, and the utilization rate of the storage space is improved. Moreover, the method adopts a mode of combined storage of the block chain network and the out-of-chain distributed storage system, so that the storage pressure of the block chain network is reduced, and the storage capacity is expanded by introducing the distributed file system. The invention further discloses a file processing device, equipment, a medium and a computer program product.

Description

Technical field [0001] This application relates to the field of blockchain technology, and in particular to a file processing method, device, equipment, and computer-readable storage medium. Background technique [0002] With the rapid development of blockchain technology in recent years, blockchain networks can be applied to almost any field. For example, there have been a large number of application cases in the fields of finance, logistics, public servers, and the Internet of Things. The application of blockchain in various fields is based on its technical characteristics such as multi-party consensus, transaction traceability, and non-tampering, so as to realize data storage. Therefore, the essence of blockchain can also be understood as a special distributed database, which is mainly used to store data. [0003] At present, when the blockchain network is used in various fields to realize data storage, with the rapid growth of business volume, the data storage pressure faced b...
