V. COLAERT Master thesis, submitted by Corrector: prof. dr. W. DEVROE Eline HOOGMARTENS As part of the final examination for the degree of MASTER OF LAW Summary FinTech, technology-enabled innovation in financial services, has developed significantly over recent years and is impacting the way financial services are produced and delivered. Perhaps the most disruptive technology in the FinTech industry is blockchain technology. Blockchain technology enables the chronologically recording, sharing and synchronizing of data in a digital system decentralised across a network of multiple datastores. The main reason that blockchain technology is disruptive is that it allows transactions to take place without any intermediary. One of the areas in which blockchain technology can play a significant role is peer-to-peer lending. P2P lending is a method of debt financing that enables individuals and businesses to lend or borrow directly from each other through an internet-based platform without the involvement of a bank. The removal of intermediaries not only leads to higher yields for the parties, it also brings significant risks. Examples include credit risk, liquidity risk, fraud, money laundering and conflict of interest. Blockchain technology is a natural ally for P2P lending as it allows transactions to take place directly between the parties in a secure and tamperproof way. Although the potential of blockchain technology for P2P lending has been suggested many times, the concrete possibilities of blockchain technology to address P2P lending risks are still waiting to be discovered. When it emerges that blockchain technology has the potential to adequately address P2P lending risks, (the impact of) regulatory measures might potentially be reduced for P2P lending platforms based on the blockchain. This interdisciplinary research paper wants to fill this gap by answering the research question: “What is the deregulatory potential of blockchain technology for peer-to-peer lending?” On the basis of a thorough analysis of the risks of P2P lending and their regulatory framework (Chapter I) and the functioning of blockchain technology (Chapter II), the research paper studies the possibilities of blockchain technology to eliminate or reduce P2P lending risks (Chapter III) with a view to evaluating the deregulatory potential of blockchain technology for P2P lending (Chapter III and Conclusion). The research paper shows that blockchain technology has an enormous potential to eliminate or reduce P2P lending risks and to support regulatory measures addressing these risks. This applies particularly to platform risk, fraud, money laundering, hacking and liquidity risk. However, (additional) regulatory measures remain necessary to adequately address several P2P lending risks. This applies particularly to credit risk, liquidity risk, conflict of interest and operational risk. Exceptions can be made for platform risk and, to a large extent, hacking. Acknowledgements I would like to thank prof. dr. Colaert (Financial Law Professor KU Leuven) for her valuable feedback and useful critiques on this master thesis and for our interesting changes of views on the potential of blockchain technology for financial law. A special word of thanks also goes to Tom Vos (PhD student KU Leuven), Sophie Peeters (Linklaters) and Arben Dervisholli (Architects for Business & ICT) for their valuable suggestions and critical remarks. i Table of contents INTRODUCTION ...................................................................................................................... 1 I.
