Problems solved by technology
[0006] In the traditional maintenance mode, due to the different warranty policies of different manufacturers, the manufacturer often needs to inform the user of the warranty policy of the product and confirm the authenticity of the product by attaching a "three guarantee card" in the product package. It is necessary to confirm the starting date of the warranty period of the product purchased by the user by issuing a purchase certificate, etc. Reduce the user's trust in the brand, can not enjoy the convenience of maintenance brought by the purchase of regular products, to a certain extent, encourages the arrogance of some unscrupulous manufacturers to produce fake and shoddy products

The invention discloses a product maintenance support system based on a block chain. The system comprises the following modules: 1) an authority verification module, which realizes the discriminationof the user authority and confirms whether the operation can be carried out; 2) a user information management module which realizes the management of the personal information of each user in the system and realizes the functions of login and registration; 3) a product numb generation module, which realizes that calculation of the unique numb of the product and is used for confirming the product information; 4) a data input module to record that information of the product in each stage of production, sale and maintenance by the manufacturer, the distributor and the maintenance company; 5) a data inquiry module, realizing the inquiry of the relevant data of the system and the bottom block chain platform. The invention solves the problem of 'three-guarantee card', purchase voucher loss and the like that consumers encounter when carry out warranty and other related activities, facilitates the maintenance of the products by consumers, and realizes the product maintenance support system based on the block chain.
Description
technical field [0001] The present invention relates to the application of blockchain, in particular to a product maintenance support system based on blockchain. Background technique [0002] Blockchain technology, blockchain is a new type of decentralized information technology, which can safely store digital transactions or other data, and the information cannot be forged and tampered with. It is the underlying technology of digital currencies such as Bitcoin and Ethereum. The transaction confirmation on the blockchain is completed by the consensus of all nodes on the blockchain, and after the consensus is successful, it is packaged and written into the block. The blockchain maintains a public account book, which is used to store all transactions on the blockchain network. Any node of the public account book located on the storage block is a complete copy, so as to ensure that it cannot be forged and tampered with, and realizes information sharing. It can improve the effi...
