appXchain: Application-Level Interoperability for Blockchain Networks

Blockchain technology has the potential to revolutionize industries by offering decentralized, transparent, data provenance, auditable, reliable, and trustworthy features. However, cross-chain interoperability is one of crucial challenges preventing widespread adoption blockchain applications. Cross-chain represents ability for network interact share with another network. Contemporary solutions are centralized require re-engineering core stack enable inter-communication sharing among heterogeneous networks. In this paper, we propose an application-based solution named appXchain which allows networks any architecture type industrial focus inter-communicate, data, make requests. Our utilizes decentralized applications as a distributed translation layer that capable communicating understanding multiple networks, thereby delegating requests parameters them. The uses incentivized verifier nodes maintain integrity shared facilitating them be readable entities their We define describe roles requirements major inter-operating in context healthcare. present detailed explanation sequence interactions needed Electronic Medical Record (EMR) document from along required algorithms. implement Ethereum-based smart contracts two hospitals also its cost security analysis. have made our code testing scripts publicly available.
