Blockchain for Transport (BC4 T), Performance Simulations of Blockchain Network for Emission Monitoring

Vehicles are becoming increasingly connected and are already transmitting substantial amounts of data to the Original Equipment Manufacturers (OEMs) servers. Blockchain (BC) enables the transmission of data with addition security and removes single points of failure, while maintaining data prove-nance, identity ownership and the possibility to retain varying levels of privacy depending on requirements of the applied use-case. This research performs emulations of vehicles interacting with European Member State authorities and the European Commission (EC) BC nodes that are running Hyperlegder Fabric (HLF) and explores whether the technology is could be used for transport applications, building on indicative case studies such as CO2 emissions monitoring and vehicle identity. Due to the specialized nature of the Experimental Platform for Internet Contingency infrastructure, the network topology can be defined allowing for more realistic network conditions to be emulated. The results show that the deployed system is able to meet the requirements both in terms of Transactions Per Second and latency, but the hardware and system parameters need modification in order to scale up to the envisaged number of vehicles in the fleet.
