So, the problem statement of this research is how the blockchain sharding concept can increase the efficiency of the process of implementing blockchain technology in the global car rental industry. The research uses qualitative methods to identify problems in implementing blockchain technology in the global car rental industry. A qualitative approach through literature reviews is also used to find more effective blockchain methods. The result of this research is an adopted blockchain sharding model in the global car rental industry. At the end of the article, a simulation using the Ganache is explained.
