【Abstract】With an exponential increase in intelligent data-driven applications in recent times, ensuring the reliability of this massive amount of data poses a great challenge. Fortunately, the advent of blockchain technologies could enable enforcing as well as managing trust in a transparent and robust manner. A trust value associated with a user or data can help prevent fraud and improve user experience. The same user or data source (an IoT device) can be a part of multiple blockchains considering the many-to-one mapping of running applications to the user (or devices) in a practical scenario. In such an ecosystem, it is important to preserve the hard-earned trust of a user across different chains. However, limited interoperability among multiple blockchains restricts the reusability and transitivity of trust realization, which would otherwise be helpful in reducing the overhead to a great extent. This naturally raises an interesting question: "How to enable a seamless flow of trust from one chain to the other without compromising the privacy of the data that would conform to the specific characteristics of individual blockchain and preserve the integrity of trust value?" In this paper, we design a novel architecture called CrossTrustchain to facilitate the interoperability of trust across different chains to address the stated problem. We also look at how the multivariate trust model can be interoperated between different chains. Finally, we conduct performance benchmarking for a banking use case scenario on Hyperledger Caliper and presented interesting results to open up newer possibilities for further research in this direction.
