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 con
