ROAD attempts to create a full lifecycle interaction and accounting system for cars based on blockchain technology, which is called autoledger. The auto-ledger is an Internet of Vehicles and intelligent transportation systems built on individual interaction and community intelligence to implement related business applications, data confirmation and privacy protection with blockchain. At the same time, the ROAD Token is created to coordinate the resource exchange between the vehicle nodes and the heterogeneous chains. Road is a business-driven project, which continues to increase the marginal effect of the overall participation population through the practice and expansion of commercial projects.
