Blockchain technology is one of the most popular technologies in the recent decade. In 2008, Satoshi Nakamoto published a paper entitled Bitcoin: A Peer-to-Peer Electronic Cash System. This paper was the starting point of this technology. As of 2017, it has been nine years since blockchain's development. During these years, blockchain has gradually developed toward industrialization from the initial technology boom. Although cryptocurrency and virtual currency transactions represented by Bitcoin fell to the bottom from the peak period of speculation in 2014, the investment of the relevant industries of blockchain in the world still rose gradually. With the deepening commercialization, the application of blockchain has been pervasive and has involved the financial sector and many other fields other than finance. Blockchain technology has revolutionized our day-to-day lives, and mass adoption of decentralized technology is predicted to happen shortly. This book has carried out valuable research in the provision of laws, rules, and systems in financial technology to make up for the shortcomings of existing research. At the same time, the book provides a large number of cases to explain how blockchain will fall, as well as the possible legal issues in landing. Blockchain and tokenomics are legal monographs in the blockchain industry that bridge the gaps in the legal reference of current blockchain business practices. This book will enable blockchain investors, blockchain entrepreneurs, and blockchain application explorers to understand the current and future practices of blockchain applications in a more transparent, more intuitive, and more comprehensive way by knowing the existing legal oversight and the future possibilities under the supervision of the work of blockchain.
