Abstract
With the development of blockchain technology, cryptocurrency has gradually became one of the financial hotspots. However, its virtuality, cross-border nature, and pseudo-anonymity have given rise to a new type of cross-border crime. Cryptocurrency essentially belongs to cyberspace, and the traditional international jurisdiction system based on the "territorial principle," constructed around physical space, struggles to cope. Countries like the United States misuse "long-arm jurisdiction," leading to a series of judicial sovereignty disputes and jurisdictional conflicts. This article, using the Chen Zhi case as an entry point, focuses on the difficulties of applying traditional jurisdictional theories in cross-border cryptocurrency crimes. Meanwhile, by adopting case study and comparative law methods, this paper deconstructs the judicial documents of the Chen Zhi case. It proposes a "reasonable connection" standard, incorporating proportionality, to assess the legitimacy of a nation's jurisdictional actions, define the boundaries of "long-arm jurisdiction," and create conflict resolution and relief mechanisms through international cooperation, aiming to balance crime fighting and the healthy development of digital finance.
