In 2008, an author using the pseudonym Satoshi Nakamoto wrote a white paper describing Bitcoin, a new decentralized cryptocurrency.⁸ Unlike past attempts at forming a cryptocurrency—attempts that relied on preestablished trusted entities for the system to operate correctly—Bitcoin's design runs on the open Internet, with no one in charge, while maintaining tight security. While the building blocks of Bitcoin were not novel, the composition of these properties into a single system was a meaningful contribution,⁹ and Bitcoin became the first cryptocurrency to achieve widespread attention.
