In the wake of the 2008 financial crisis, the mysterious Satoshi Nakamoto published a revolutionary white paper that described a simple peer-to-peer electronic cash system that would later become Bitcoin, laying the foundations for the technical innovation known as the blockchain. In the decade since its publication, the nascent technology behind cryptocurrency has become recognised holding the same transformative potential of the printing press or the internet, set to impact our sense of identity and provenance as much as finance. It has disrupted traditional financial markets with a spectacular explosion in value, paved the way for thousands of similar digital currencies and laid the groundwork for a decentralised future of the web. But what does it mean for everyday life? The White Paper returns to the document that started it all, taking Nakamoto’s text as a Rosetta Stone to decode the meaning of blockchain for contemporary society. This guide to the innovative technology shows how it holds up a mirror to our understanding of the world, both timeless and mutating: from the archetypal origin story, to concepts of trust and value, and the changing shapes of power and privacy.
