Secure Distributed Network Model to Store Vehicle Transaction Records Through Blockchain Platform

Blockchain is an emergent technology applied initially to cryptocurrencies, but with a much further reach. We present a secure, transaction-based system that handles motorized vehicle provenance (including ownership) over a distributed model using smart contracts on a blockchain. The system model includes the specification of various security protocols, verified using AVISPA-SPAN tool and guaranteeing privacy, authenticity, and other security features. A client of the system can have different roles accordingly to the relationship it has with the vehicle, and it can get various services and request transactions accordingly. Our proposal might contribute to reduce fraud and expand the applications of Blockchain.
