Enhancing Blockchain Interoperability Through Cross-Chain Outsourcing and Communication

The shortcomings of blockchain technology, previously concealed, are now known to specialists and academics as blockchain technology has grown in popularity. The most basic idea at the heart of centralized technology is interoperability, but connecting interoperation with blockchain will trigger more challenges. The fundamental cryptography of blockchain technology causes issues with interoperation across connected blockchains. Scholars are continually working on solutions for cross-chain operations from blockchain birth till now. Some of these measures ensure that tokens are equivalent to one another. Some of them rely on side-chain technology, and some of them rely on centralized trading centers. However, will the new solution be able to gather the experience of its predecessors and build a more complete blockchain cross-chain interoperability scheme? Is it feasible to create a global platform for cross-chain operations that would enable the interoperability of common blockchain features and provide solutions for the interoperability challenges posed by non-uniform aspects? This study strives to investigate the solution and viability of the solution using the action research approach by combining the papers and reports of earlier researchers. Finally, this paper proposes an easier-to-use cross-chain interoperability framework by synthesizing the experiences of previous scholars. Results show that this framework is the easiest to extend and interface. This framework can support cross-chain operations for all kinds of blockchain.
