Research on Cross-chain Technology of Blockchain: Challenges and Prospects

Abstract

As one of the core technologies of blockchain, cross-chain technology has been widely valued by academia and industry, and has made a series of research achievements in recent years. At present, the overview research on cross-chain technology generally compares and analyzes cross-chain technology as a whole, and lacks the decoupling comparison of the main steps in cross-chain technology. Firstly, the basic principle of cross-chain technology is summarized and analyzed. Then, the cross-chain technology is divided into two types: isomerism and isomorphism, and the existing problems and corresponding solutions are analyzed and compared. Finally, the development status and trend of cross-chain technology are summarized, as well as important research directions in the future.
