Embodiment Construction
[0046] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0047]A blockchain is a decentralized database consisting of a continuously growing list of records called blocks. Each block contains a timestamp and a link to the previous block: the blockchain is designed so that the data cannot be tampered with, and once recorded, the data in a block is irreversible. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system. Blockchain (Blockchain) is...

The invention discloses a method and device for updating vehicle information. The vehicle management station node receives the first broadcast message broadcast by the first user in the block chain and obtains the first user information, first vehicle information and second vehicle information carried in it. Information; receive the second broadcast message broadcast by the second user in the blockchain and obtain the second user information, first vehicle information and second vehicle information carried in it; if the first user information, second user information, first If the vehicle information and the second vehicle information are correct and the first vehicle information and the second vehicle information meet the preset update conditions, a relationship query request message including the first user information and the second user information is broadcast in the blockchain; The node broadcasts the query result message and obtains the query result carried in it. If the first user and the second user are determined to be immediate relatives according to the query result, update the first vehicle information and the second vehicle information and broadcast the update in the blockchain network Successful broadcast message.
Description
technical field [0001] The present invention relates to the technical field of blockchain, in particular to a method and device for updating vehicle information. Background technique [0002] Two car owners who are immediate family members each own two non-operating private vehicles, and the license plate numbers of the two cars belong to the same city. If the two car owners want to exchange the license plate numbers of the two cars, there is no way The vehicle update method can update vehicle information while ensuring information security. Contents of the invention [0003] Therefore, the present invention provides a method for updating vehicle information to solve the problem in the prior art that two car owners who are immediate relatives cannot exchange the license plate numbers of their private vehicles due to the lack of a method for updating vehicle information. [0004] In order to achieve the above purpose, the first aspect of the present invention provides a me...
