Surveys the phenomenon of bitcoin, blockchain, and other emanations from the realm of ‘trustless’ digital currency circa late 2014. Beginning with an overview of fiat currencies and a discussion of the opposing views of money as a store of value or a means of exchanges, the book then presents simplified explanations of bitcoin, the blockchain ledger than enables its interchange, and related digital currency projects, and highlights of spectacular business successes and scandals. Competing views within the development community are surveyed, and several new projects assessed. The promise of helping the ‘unbanked’ and black market opportunities are less jolting that the dystopian possibilities presented by blockchain applications. Undoubtedly soon to be dated, and reflects establishmentarian liberalism, but effectively done.
