ABSTRACT
This chapter presents a car registration system based on the Hyperledger Fabric blockchain technology. Blockchain enables the development of decentralized business models with enhanced security for critical data. The decentralization provided by blockchain technology can be considered a direct competitor to organizations relying on a centralized business model, such as banks and governments. A car registration system based on blockchain can decentralize this kind of registries and, in consequence, improve data availability and resilience to faults. Smart Contracts are programs written to form agreements between users in the blockch. Public blockchains rely on public nodes; thus any node can contribute to the network by running a client designed to keep a local blockchain copy, contribute to network consensus, contribute to process transactions and create blocks. Applying blockchain technology to a business may lower operations costs and coordination efforts, as the system automatically handles possible conflicts.
