Blockchain is a new general-purpose technology that poses significant challenges to policymaking, law, and society. Blockchain is even more distinctive than other transformative technologies, as it is by nature a global technology; moreover, it operates based on a set of rules and principles that have a law-like quality—the lex cryptographia. The global nature of blockchain has led to its adoption by international organizations such as the United Nations and the World Bank. However, the law-like nature of the technology makes some of its uses by international organizations questionable from an international law and foreign affairs perspective. In this light, the article examines the effectiveness and legitimacy of the use of blockchain for international policymaking.

国际组织使用区块链：有效性和合法性

区块链是一种新的通用技术，对政策制定、法律和社会提出了重大挑战。区块链比其他变革性技术更具特色，因为它本质上是一项全球技术；此外，它的运作基于一套具有法律性质的规则和原则——lex cryptographia。区块链的全球性导致其被联合国和世界银行等国际组织采用。然而，从国际法和外交事务的角度来看，该技术的法律性质使得国际组织对其的一些使用存在疑问。有鉴于此，本文研究了使用区块链进行国际决策的有效性和合法性。
