Popis:	Both blockchain and Internet of Vehicles (IoV) are emerging technologies that attract interest from academia and industry. Deploying blockchain peers on vehicles enables corporation, coordination, trust, security, and privacy in the IoV. However, the peers are deployed on resource-constrained on-board computing devices, and have high mobility, which causes significant challenges on the blockchain. The blockchain’s consensus mechanism must be efficient and energy-saving. In this paper, a proof-of-stake consensus mechanism is presented that uses tickets and sorters to address this issue. The proposed consensus mechanism prevents users from controlling the blockchain by hoarding a large number of coins, and reduces the cost of message communication during the election of the leader and verifiers. The performance of this mechanism could be further improved if the IoV was built over 5G communication channels.
