TL; DR
<aside> 💡 The cross-chain bridge (otherwise known as blockchain bridge) is not a new topic. Still, the articles on the market have comprehensively classified and interpreted the cross-chain bridge from the fundamental elements of the bridge and the cross-chain technology. However, the classification of cross-chain bridges in current papers is dizzying and hinders people from understanding the performance of cross-chain bridges from the macroscopic angle.

<aside> 💡 Dr. DODO aims to analyze and compare the performance of all aspects of the "bridge" based on the investigation of 16 cross-chain bridges. By comparison, people can intuitively understand the differences between bridges and the problems they are committed to solving, reflecting the future development trend of cross-chain bridges. The focus of this article is to compare the performance of the cross-chain bridges rather than to give an in-depth explanation of the cross-chain technology itself. Readers can use the references cited in this article to popularize knowledge of cross-chain technology.
