Blockchains: Regulating the Unknown
Published online by Cambridge University Press: 06 March 2019
Abstract
This Article, which takes into account developments up until summer 2017, evaluates the early days of regulatory engagement with blockchain technology. My analysis unfolds in three parts. First, I provide a cursory overview of the technology itself to highlight considerable uncertainties concerning its future. Regulators asked to engage with distributed ledgers are thus compelled to regulate the unknown. Second, I will introduce a typology of regulatory strategies adopted to date and highlight their respective advantages and shortcomings. Third, I will outline a number of guiding principles regulators should follow in respect of blockchain technology. I will make the argument that despite the technology's uncertain future, early regulatory engagement is warranted as a young technology is a malleable technology. As technology develops, law has to adapt. As a consequence, I put forward a number of regulatory techniques, including a process of polycentric co-regulation that relies on the regulatory potential of (blockchain) software and the adoption of a so-called “28th regime” at the EU level which may help navigate the uncertainties of blockchain development and regulation.
