Embodiment

[0024] A blockchain-based data storage method, comprising the steps of:

[0025] a. Receive the upload storage request of the electronic data deposit, generate a globally unique identifier, obtain the unique number of the hard disk where the electronic data deposit is located, the MAC address and time of the requesting host, and at the same time, store the electronic data and the hard disk The unique number, the MAC address of the requesting host and the time are hashed to obtain the hash value C;

[0026] b. Send the globally unique identifier and hash value obtained in step a to the message queue center as a message, and feed back the globally unique identifier of the electronic data deposit to the uploading storage requester of the electronic data deposit ;

[0027] c. Deploy multiple modules for obtaining messages connected to the message queuing center. The modules for obtaining messages obtain message data in parallel from the message queuing center, and call the interf...

Abstract

The invention discloses a block chain-based data storage method, which comprises the following steps of a, receiving an uploading storage request of an electronic data storage, generating a global unique identifier, and carrying out Hash operation to obtain a Hash value C; B, sending the globally unique identifier and the hash value as messages to a message queue center, and feeding back the globally unique identifier of the electronic data storage certificate to an uploading storage requester of the electronic data storage certificate; C, deploying a plurality of modules which are connected with the message queue center and are used for acquiring messages, parallelly acquiring message data from the message queue center by the modules used for acquiring the messages, and calling an interface of a block chain network to store the data into a block chain; and d, inquiring whether the stored global unique identifier and the hash value C of the electronic data storage exist in the block chain, if so, finishing storage, if not, putting the global unique identifier and the hash value C of the electronic data storage into the message queue center again, and repeating the step c.

Description

technical field [0001] The invention relates to the technical field of data storage and traceability, in particular to a blockchain-based data storage method. Background technique [0002] The traditional data storage and data traceability technology is based on the database to store files. The traditional data storage method only saves the latest data storage status, does not have the characteristics of unalterable, data storage and data traceability, and cannot Really achieve the purpose of data storage and data traceability. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides a blockchain-based data storage method. [0004] The technical scheme adopted in the present invention is: [0005] A blockchain-based data storage method, comprising the steps of: [0006] a. Receive the upload storage request of the electronic data deposit, generate a globally unique identifier, obtain the unique number of...
