Above All Waves introduces English readers to the life and ideas of Tominaga Nakamoto (1715–1746), a maverick Japanese philosopher rumored to have been an inspiration for the inventor of Bitcoin known only by the pseudonym Satoshi Nakamoto. In January 2009, Satoshi released Bitcoin, a decentralized digital cash currency that allows anyone to use and develop its software. The rest is history. The identity of Satoshi remains a mystery to this day. But rumors during the early days of Bitcoin suggest Satoshi was inspired in part by Tominaga Nakamoto, an obscure and largely forgotten 'merchant' philosopher from the eighteenth-century Edo period in Japan. Tominaga's philosophical and aesthetic ideas are radical even by today's standards. And it is not hard to see how his most vital insights–the need to decentralize authority among them–echo in how Bitcoin functions as a cryptocurrency. Newly translated by the noted Yuzo Sakuramoto, Above All Waves distills Tominaga's most audacious writings into a set of quotes and passages that captures the forwarding-thinking quality of his thought. A critical introduction by Paul Chan tells the story of Tominaga's remarkable life and speculates on the rumored relationship between Satoshi and Tominaga, as well as how Tominaga's outlook may have influenced how Bitcoin exists as a technology and cultural phenomenon. Artwork by Chan captures the spirit of Tominaga's world and recasts the philosopher in compositions that attempt to express his enduring influence.
