It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

A blockchain is a decentralized database that contains a list of blocks called blocks, with continuously growing and neatly arranged records. Each block contains a timestamp and a link to the previous block: the blockchain is designed so that data cannot be tampered with, and once recorded, the data in a block is irreversible. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that realizes the establishment of trust between different nodes and the acquisition of rights and interests in the blockchain system. Blockchain is an important concept of Bitcoin. The "2014-2016 Global Bitcoin Development Research Report" released by Huobi.com, Tsinghua University PBC School of Finance Internet Finance Laboratory, and Sina Technology mentioned that blockchain is the The underlying technology and infrastructure of Bitcoin is essentially a decentralized database and serves as the underlying technology of Bitcoin. A blockchain is a series of data blocks that are associated using cryptographic methods. Each data block contains the information of a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. In a narrow sense, blockchain is a chained data structure that combines data blocks in sequential order according to time sequence, and is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger. Broadly speaking, blockchain technology is the use of blockchain data structures to verify and store data, the use of distributed node consensus algorithms to generate and update data, the use of cryptography to ensure the security of data transmission and access, and the use of automated scripts. A new distributed infrastructure and computing for programming and manipulating data using smart contracts composed of code. The design of the blockchain is a safeguard, such as (applied to) a highly fault-tolerant distributed computing system. Hybrid consistency is made possible by blockchain, which is suitable for recording events, titles, medical records and other activities that require data to be included, identity management, transaction flow management and provenance management. Blockchain has huge potential for financial disintermediation and has a huge impact on leading global trade. The concept of blockchain was first proposed by Satoshi Nakamoto in 2008, and in the years that followed, Bitcoin became a core component of electronic money: as a public ledger of all transactions, through the use of peer-to-peer networks and distributed time The poke server, the blockchain database can be managed autonomously, the blockchain invented for Bitcoin made Bitcoin the first digital currency to solve the problem of repeated consumption, and the design of Bitcoin has become a source of inspiration for other applications.

Correspondingly, in the above step 8, the process of encrypting the locally stored first user information, first vehicle information, second user information and second vehicle information by the vehicle detection factory node according to a preset algorithm may include: vehicle detection; According to the two license plate numbers obtained from the successful update broadcast message, the factory node queries the local database to obtain the name, ID number, engine number and the validity period of the annual inspection time corresponding to the license plate number, and calculates each name and ID number according to the preset algorithm. , the hash value of the engine number and the validity period of the annual inspection time, so that the encrypted first user information and the second user information of this node include the hash value of the name, part of the plaintext of the name, the hash value of the ID number and the ID card. Part of the hash value of the number, so that the encrypted first vehicle information and the second vehicle information both include the license plate number, the hash value of the engine number and the hash value of the validity period of the annual inspection time.

In the above step 8, the process of verifying the first user information, the first vehicle information, the second user information and the second vehicle information obtained from the update successful broadcast message by the vehicle inspection factory node may include: the vehicle inspection factory node compares this node The encrypted first user information is compared with the first user information obtained from the update successful broadcast message, the second user information encrypted by this node is compared with the second user information obtained from the update successful broadcast message, and the calculated value of this node is compared. Calculate the hash value of the engine number of the first vehicle and the hash value of the validity period of the annual inspection time and the hash value of the engine number of the second vehicle and the hash value of the validity period of the annual inspection time obtained from the update successful broadcast message. The hash value of the engine number of the second vehicle and the hash value of the validity period of the annual inspection time are the same as the hash value of the engine number of the first vehicle and the hash value of the validity period of the annual inspection time obtained from the update successful broadcast message (at this time, the local The stored license plate numbers of the first vehicle and the second vehicle are opposite to the license plate numbers of the first vehicle and the second vehicle in the update successful broadcast message. Therefore, the locally stored engine number of the first vehicle and the validity period of the annual inspection time actually correspond to the successful update. The license plate number of the second vehicle in the broadcast message), if they are all consistent, it can be considered that the vehicle inspection factory node has successfully verified and updated the first user information, first vehicle information, second user information and second vehicle information in the broadcast message. .
