Interworking Mechanism of Blockchain Platforms for Secure Tourism Service

Abstract

Since the launch of Bitcoin in 2009, research on blockchain technology has rapidly raised in the field of study and application. Blockchain technology shows the great potential to address interoperability challenges in current IT systems and is hoped to become a part of the core technical standard, enabling individual stakeholders to share data more securely. However, blockchain technology is still in its infancy and requires more improvement. At present, the common problems of blockchain are low efficiency and poor scalability. Most of the existing blockchain systems are built on single chains, which lacks the solution for enterprise applica tions. In this paper, we present an interworking mechanism to enable cross-domain communica tion for multiple chains. This proposed architecture combines private and public chains to form the network infrastructure, and the interaction is achieved through a routing management ap plication. This application acts as the intermediate between multiple chains, which transmits the data from one to another chain. The blockchain network can be extended to support more parallel chains according to different business requirements. This paper applies the multiple chain architecture schemes to secure tourism services and verifies the feasibility of the proposed architecture. The proposed secure tourism service platform consists of three main components: the main-chain, sub-chain, and interworking app. To demonstrate the usability of the proposed approach, a proof of concept is implemented using WindingTree and Hyperledger Fabric. The efficiency of the designed approach is demonstrated through a series of experimental tests using different performance metrics.
