Cryptocurrencies are often associated with right-wing political movements, or even with the alt-right. They are the preserve of libertarians and fans of Ayn Rand and Friedrich Hayek. With their promotion of anonymity and individualism, thereisquo;s no doubt that they seamlessly slot into the prevailing anti-State ideology. But in this book Mark Alizart argues that the significance of cryptocurrencies goes well beyond cryptoanarchism. In so far as they allow us squo;to appropriate collectively the means of monetary productionlsquo;, to paraphrase Marx, and to replace csquo;the government of persons by the administration of thingsssquo;, as Engels advocated, they form the basis for a political regime that begins to look like a communism which has at last come to fruition adash; a cryptocommunism.
