The blockchain‐based management system has been regarded as a novel way to improve the efficiency and safety of Vehicular Ad Hoc Networks (VANETs). A blockchain‐based scheme’s performance depends on blockchain nodes’ computing power composed from the road‐side unit (RSU). However, the throughput of blockchain‐based application in VANETs is limited by the network bandwidth. A single blockchain cannot record large‐scale VANETs’ data. In this paper, we design an atomic cross‐chain swap‐based management system (ACSMS) to boost the scalability of blockchain‐based application in VANETs. The blockchain‐based public‐key encryption with keyword search is further introduced to protect user privacy. The analysis shows that ACSMS achieves cross‐chain swap without loss of CAV security privacy. The simulation results show that our method can realize multiple blockchain‐based applications in VANETs.
