Blockchain is the first global mechanism for the transfer and storage of value. Despite being conceived as an alternative to state and law, the technology and its use cases raise many legal questions, most notably, regarding jurisdiction and applicable law with respect to transactions and assets recorded on the blockchain. The issue is complex given the decentralised nature of the network. In this volume, academics and practitioners from various countries try to provide detailed answers to these questions as they relate to crypto-assets, cryptocurrencies, crypto derivatives, stablecoins, Central Bank Digital Currencies and Decentralised Autonomous Organisations (DAOs), as well as specific transactions and issues, such as property rights, secured transactions, smart contracts and bankruptcy. With specific chapters on national approaches (Germany, Japan, Liechtenstein, Switzerland, United States), the volume explores the need and possibility for legal harmonisation of these issues through global fora, such as the Hague Conference on Private International Law (HCCH) UNIDROIT.
