The 'Preamble' chapter of 'Blockchain and the Law: The Rule of Code' serves as the introductory front matter of the book, presenting bibliographic and publication details, authorship, and dedication. It sets the formal context for the work, acknowledging the foundational contribution of Satoshi Nakamoto to blockchain technology. No substantive legal or technical discussion is presented in this section.

This chapter introduces the regulatory challenges posed by decentralized, blockchain-based systems, tracing their origins to the cypherpunk vision of crypto anarchy. It explains how blockchains operate as tamper-resistant, decentralized databases enabling pseudonymous economic transactions and autonomous smart contracts, while highlighting their potential to disrupt traditional legal, financial, and governmental frameworks. The chapter emphasizes the dual-use nature of blockchain technology, which can both support lawful services and facilitate illicit activities, thus complicating regulatory efforts.

The chapter explores the rapid expansion of personal data generated by mobile and IoT devices, emphasizing the privacy challenges and the necessity for user-centric control in data sharing. It introduces decentralized personal data markets, exemplified by the Enigma platform, which leverages blockchain and secure multi-party computation to enable privacy-preserving data monetization while ensuring data owners retain control over access and usage. The chapter concludes with an extensive interdisciplinary reference list supporting the development of decentralized, privacy-focused data sharing frameworks that balance economic value with user trust and transparency.

Chapter 10 serves as an introductory segment outlining the extensive research and methodology behind the book, including the author's extensive interviews with key Ethereum figures and use of blockchain data analytics. It also provides a detailed list of major characters involved in the Ethereum ecosystem and related projects, as well as a preface that contextualizes the rise of cryptocurrency from the 2008 financial crisis through the explosive growth of Bitcoin and Ethereum up to mid-2017. The chapter highlights the technological innovation of blockchain, the diverse groups attracted to cryptocurrency, and the dramatic market expansion fueled by ICOs and institutional interest.

The chapter critiques Facebook's Libra project for its vague and technologically reductionist approach to 'banking the unbanked,' highlighting the complexity of financial inclusion as a social and local process rather than a mere technical problem. It contrasts Libra's blockchain-based solution with successful grassroots models like Kenya's M-Pesa, emphasizing the necessity of understanding local conditions, privacy concerns, and regulatory realities. The chapter argues that Libra's plan lacked concrete strategies and failed to address the real barriers faced by unbanked populations in both developing and developed countries.
