Abstract
Due to the rapid development of various transport platforms, including those using unmanned technologies, systems that provide storage of vehicle operating history throughout its lifecycle are becoming increasingly relevant. Purpose: the purpose and functionality of the developed system for storing such information are defined. The main purpose of the system is to maintain a single source of reliable and unchangeable information about the operating history of the vehicle. Such a system can increase the transparency of business processes that arise between participants in the automotive industry: manufacturers and owners of vehicles, service stations, insurance companies and other industry participants. Methods: Blockchain technology, smart contracts and various methods of transaction processing were used. Results: the system was designed based on a distributed platform, based on the criteria defined in the work, Hyperledger Fabric was chosen as the platform. Communication network and information system architecture were designed and developed based on the distributed registry technology. The paper describes the process of creating the Hyperledger Fabric network, which is supported by the member organizations of the automotive industry. A description of the basic elements of the system is presented, as well as the mechanisms that maintain and harmonize the distributed registry, transaction processing, execution of smart contracts and interaction of the connected system participants. The hardware was designed in the form of a plug-in unit, which implements the functions of collection and pre-preparation of data collected from the nodes, units, sensors of the vehicle, as well as additional sensors built into the hardware unit. The collected data are transmitted from the block to the storages, the maintenance of which is carried out by the system participants interested in such data. The fact of data transfer and data source identifier is recorded in a distributed registry in the form of a transaction, placed in the block. Practical relevance: On the basis of smart contract technology the issues of forming reports on the history of vehicle operation are considered. The system is scalable and allows the deployment of new smart contracts, which provides the ability to create new scenarios for its use. Discussion Possible variants of further development and use of the system are considered: the solution of scaling the system by local zones is proposed, and a brief overview of the approach of dynamic channel definition Hyperledger Fabric using dedicated near-field data communication is presented.
