Rather than take the magic to the press, the 21 Bitcoin Computer landed direct to Amazon for pre-order by enthusiasts, developers, and suckers. Units will actually ship in November 2015. The Bitcoin magic happens on silicon designed by 21 running as a co-processor to the Raspberry Pi. It provides a constant stream of Bitcoin and the software to make that Bitcoin useful for buying and selling digital goods. More usefully, there’s also Bitcoin transaction software that the makers say let customers trade the cryptocurrency, offer transaction services, and the like. Vulture South will take the 21 Bitcoin Computer more seriously when we hear that of thousands of them replacing ASIC-based HPC kit in Hong Kong skyscraper data centres. Other boosters of the project include Andreessen’s partner Horowitz, former Cisco CTO Padmasree Warrior, and former US treasury secretary Larry Summers.
