Decentralized distributed storage method based on block chain

Abstract

The invention belongs to the technical field of intelligent operation and maintenance management, and particularly discloses a block chain-based decentralized distributed storage method, which comprises the following steps of: acquiring a related data record, and uploading the data record to a block chain or an IPFS (Internet Protocol File System) for storage through an intelligent contract of the block chain; after a data record is uploaded to the block chain, the data is stored in different fragments of the block chain according to the data type of the data record, after consensus is carried out through a Hashgraph consensus mechanism, the data is discharged out of the block and is subjected to chaining storage, and the hash value of the storage content returned by the IPFS is also stored in the corresponding fragment to serve as a unique identifier; and the user obtains the required intelligent production equipment operation and maintenance data from the block chain and the IPFS through the intelligent contract. According to the invention, the fragmentation technology and the IPFS are utilized to effectively reduce the storage pressure of the block chain, the intelligent level and the operation and maintenance efficiency of the equipment are improved, and the unique identifier in the IPFS is utilized to solve the problems of unsafe transmission, redundant storage, high storage cost and the like existing in the traditional HTTP protocol.

[0002] With the advent of Industry 4.0, the Industrial Internet of Things has been widely recognized and applied in the production industry, which has improved the level of equipment intelligence and operation and maintenance efficiency, but at the same time brought a series of security issues in data and equipment control , For example, the data collected from the front end of the Industrial Internet of Things is transmitted to the cloud database for storage through the network. The security and traceability of the data cannot be guaranteed, and the reliability of the data cannot be guaranteed. The emergence of the blockchain can better solve the above data. Security issues, but the relevant research did not take into account the data volume in the industrial Internet of Things with the increase in the frequency and amount of collection, the lack of storage space and performance degradation faced by the blockchain itself
