CarChain: A Novel Public Blockchain-based Used Motor Vehicle History Reporting System

摘要

Blockchain Technology has been proposed to tackle author, centrality and storage issues. It converts centralized applications into dynamic distributed ones. Many researchers have proposed protocols and applications for mapping the old central applications into blockchain based distributed application. In this work, new system framework for Public World Wide Used Motor Vehicle History Reporting System, named CarChain, is proposed and designed. The new framework has not been constructed based on any of the popular well-known public blockchain networks. The framework constructs a peer-to-peer (P2P) overlay network that broadcasts transactions as any end system multicasting system in P2P live streaming applications. The framework allows car owners, repairing companies and insurance agencies to register and add new histories for cars in a simple method. Four different smart contracts control block updates in CarChain. In addition, database technology has been leveraged to cache intermediate data. We show in this paper the challenges and research opportunities that encounter blockchain based applications, such as CarChain.
