Abstract:
Today's ride sharing is a centralized trust based system where users trust the
service providers for the ride set up, tracking, cancellation, fare calculation etc. Any
malicious activity in the centralized server based system or a malicious driver or a
malicious rider destroys the fairness involved in the ride and causes inconvenience to
the parties. After the completion of the ride, the drivers are rated by the riders. There
are possibilities that, a malicious rider can claim the refund with a fake complain and
give the driver poor rating intentionally or a malicious driver follows a longer path
unnecessarily and charges the rider more.
Current system is not capable of deciding the correctness of the objections raised
by either parties regarding the ride and provides a biased outcome of each objections
as per the centralized company's marketing strategies. In this context, we present
BlockV, a blockchain enabled anonymous permissionless solution to ensure end to
end fairness of the ride. The creation, completion, dissatisfaction or abortion of any
ride will be written in the blockchain ledger, hence will be available to all participants
in the peer to peer network. This simultaneously ensures the fairness in maintenance
of the inbuilt reputation system. We have implemented a prototype in Ethereum
private network and KOVAN test network and analyzed the security.
