This book brings together experts from different fields and with different jurisdictional focuses to provide fresh ideas and deep insights into crypto regulation. Cryptoassets engage many different areas of law, with their own specific terminologies, uncertainties, and regulatory fragmentation.Unsurprisingly, then, crypto has faced calls for new laws, for reform of existing laws, and in some instances outright banning.Against this backdrop, this collection explores different aspects of crypto regulation, with reference to current developments, such as the Markets in Crypto-Assets Regulation, and technological innovations, including central bank digital currencies, smart contracts, and non-fungible tokens.Market, user and law-/policy-maker perspectives are examined to explore not only innovation and opportunities, but also regulatory and policy challenges.This volume will be a key resource for scholars and practitioners of law, finance, public policy, criminology and economics.It was originally published as a special issue of Law and Financial Markets Review.
