Beyond bitcoin, blockchain technology has acquired attention and importance in its own right. Today, it is conceptually accepted that blockchain stands out as a disruptive technology that will change a number of processes in financial services and could in turn impact corporate governance. This paper explores the recent applications of blockchain technology in financial services and outlines regulatory responses, to set the scene for future work in this area on corporate governance. This paper provided background for the Corporate Governance Committee's roundtable discussion on blockchain technology and the implementation of the G20/OECD Principles of Corporate Governance on 10 April 2018. A subsequent presentation of the paper was given at the OECD Workshop on Digital Financial Assets on the 16 May 2018, and at the OECD-Asian Roundtable on Corporate Governance in Malaysia on 7-8 November 2018. This work also provides a contribution to the work of the OECD Blockchain Policy Centre.
