A Blockchain‐Based Vehicle Condition Recording System for Second‐Hand Vehicle Market

Abstract

Due to the cheap price and decent performance of used cars, the second-hand vehicle market is quite active in Taiwan. However, the vehicle information in the market of second-hand vehicles is centralized at present. In other words, the vehicle information is still provided by the second-hand vehicle dealers, which are not transparent and have no tampering cost. As the result, the authenticity, accuracy, and fairness of these second-hand vehicle data are worth discussing. To solve the above problems, this paper proposed a trusted vehicle data source system based on blockchain technology. The system is built on the Ethereum platform with the private chain structure. With the help of our platform, a trusted third party (e.g., maintenance plant and government branch) can record vehicle information into Blockchain so the integrity of vehicle information can be maintained. Customers can easily query the relevant vehicle information through our system interface and avoid receiving fake vehicle information. This system is a Proof of Concept (PoC), and the feasibility is examined by evaluating transactions per second (TPS) of the proposed system.

Implementation of a Distributed Framework for Permissioned Blockchain-Based Secure Automotive Supply Chain Management

“…Using this framework, the car owners, repair companies, and insurance agencies register and add car histories in a hyperledger that has the potential to store information along the production chain to allow for association and warrant information integrity. Similar work was presented by Jiang and Sun that secures vehicle condition data of used vehicles [ 29 ]. Another closely related work is by Reimers et al who presented a proof-of-concept prototype of the integration of blockchain and the Internet of Things (IoT) in a car supply chain [ 30 ].…”

NFT-Vehicle: A Blockchain-Based Tokenization Architecture to Register Transactions over a Vehicle’s Life Cycle

“…Jiang and Sun [13] proposed a model for the second-hand vehicle market in Taiwan wherein vehicle transactions were stored in an Ethereum blockchain platform. Their model included different roles that could execute transactions at different moments in the life cycle of a vehicle: manufacturer, maintenance plant, government branch, and customer.…”

“…We discovered previous studies incorporating blockchain that primarily focused on addressing the problem of odometer fraud, but they did not incorporate blockchain-based transactions involving different parties [4][5][6]. Conversely, certain studies have considered multiple stakeholders in transactions throughout a vehicle's life cycle [7][8][9][10][11][12][13]; however, none of these integrated the concept of a legal owner, which we introduce herein. Furthermore, when it comes to tokenizing physical cars into NFTs, there remains a scarcity of studies [14,15].…”
