“…Chanson et al [4] focused on the application of blockchain to vehicular odometers. They presented a system wherein a dongle retrieves the odometer values and the VIN of the car via the onboard diagnostics II (OBD-II) interface and sends the data via Bluetooth to a laptop in the car; then, the car sends the data into Ethereum network using Web3 with the Node.js application.…”

“…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.…”

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

The sale of second-hand vehicles is a popular trade worldwide, and vehicle fraud is currently a common issue, mainly because buyers can lack a complete view of the historical transactions related to their new acquisition. This work presents a distributed architecture for stakeholders to register transactions over a vehicle’s life cycle in a blockchain network. The architecture involves a non-fungible token (NFT) linked to a physical motorized vehicle after a tokenization process, which denote as the NFT-Vehicle. The NFT-Vehicle is a hierarchical smart contract designed using an object-oriented paradigm and a modified version of the ERC721 standard. Every stakeholder engages with the NFT-Vehicle through distinct methods embedded within a smart contract. These methods represent internal protocols meticulously formulated and validated based on a finite-state machine (FSM) model. We implemented our design as a proof of concept using a platform based on Ethereum and a smart contract in the Solidity programming language. We carried out two types of proof: (a) validations, following the FSM model to ensure that the smart contract remained in a consistent state, and (b) proofs, to achieve certainty regarding the amount of ETH that could be spent in the life cycle of a vehicle. The results of the tests showed that the total transaction cost for each car throughout its life cycle did not represent an excessive cost considering the advantages that the system could offer to prevent fraud.

“…Third, IS research has often focused on technical issues of the underlying smart contract-enabling blockchain technology in isolation, such as the lack of privacy, security or scalability and different development standards (Atzei et al, 2017; Christidis and Devetsikiotis, 2016; Coblenz et al, 2019; Destefanis et al, 2018). For example, previous research has developed protocols that allow for preserving data integrity (Nugent et al, 2016) or privacy (Chanson et al, 2017; Kosba et al, 2016) features.…”

Blockchain technology has enabled so-called smart contracts between different parties on a decentralized network. These self-enforceable and self-executable computerized contracts could initiate a fundamental paradigm shift in the understanding and functioning of our legal practices. Opportunities for their application are increasingly understood, and numerous tests of feasibility have been completed. However, only very few use cases have yet been implemented at scale. This article—as the first of its kind—comprehensively analyzes the underlying challenges and locates a key reason for the slow adoption in the discrepancy between legal requirements and IT capabilities. Our work combines a wide range of academic sources and interviews with 30 domain experts from IT, the legal domain and private industry. First, we establish that smart contracts still fall within the boundaries of the general legal framework. We then systematically dissect current shortcomings of smart contracts on three distinct levels, namely, (1) how smart contracts are likely to cause conflicts with existing laws, (2) how smart contracts are intrinsically limited on an individual contract level and (3) how they are impeded by their current technical design. Across those levels, we dissect 20 distinct issues concerning the current implementation of smart contracts for which we derive potential remedies. We further outline implications for policy-makers as well as IT management, and examine how information systems research can play an important role in advancing smart contracts. Finally, we show how managerial and organizational issues might represent an ongoing challenge for the widespread adoption of smart contracts.

“…A few studies explore whether or not blockchain technology may reduce information asymmetries in the automotive market by creating a blockchain-based vehicle history. Odometer values can be securely stored in a public blockchain system to address the problem of odometer fraud by using sensor data from vehicles (Chanson, Bogner, Bilgeri, Fleisch, & Wortmann, 2019;Chanson, Bogner, Wortmann, & Fleisch, 2017). Notheisen et al (2017) propose a public blockchain-based car register system and show that it is capable to reduce transaction risk resulting from immutability of blockchain transactions and minimize quality uncertainty by providing reliable, transparent, and complete vehicle history.…”
