With the emergence of Ethereum smart contracts, the number of blockchain platforms and decentralized applications has increased rapidly. However, most of the existing blockchain networks operate in an isolated environment, which brings about the scalability and connectivity issues of the blockchain platform and limits its development. Blockchain cross-chain technology has attracted much attention since the birth of Bitcoin. Its purpose is to realize the interconnection between chains and increase the interoperability of blockchains. It is the essential capability of the future blockchain interconnection network. This article systematically analyzes and summarizes the implementation schemes and projects of cross-chain technology. Firstly, it introduces the background and development history of blockchain cross-chain technology and explains the basic scheme of the cross-chain mechanism. Next, it elaborates on the implementation of three cross-chain applications. In the summary section, the advantages and disadvantages of the cross-chain mechanism and multiple cross-chain applications are summarized. Finally, several future research directions of cross-chain technology are listed.
