A study on the challenges and solutions of blockchain interoperability

With the development of blockchain technology, a variety of mutually independent blockchains such as Bitcoin and Ethereum, as well as private and consortium chains, coexist in large numbers. As a linker of the blockchain network, blockchain interoperability will link more blockchain ecosystems, realize the interconnection of the blockchain and enhance the scalability of the blockchain. This paper summarizes typical blockchain interoperability projects. Firstly, it proposes a blockchain interoperability definition and an architecture model. Secondly, it analyzes technical characteristics of blockchain interoperability, and typical blockchain interoperability cases are compared. Finally, the trend of future development of blockchain interoperability technology is summarized and discussed.
