People compare Bitcoin to the Internet. Well, the Internet required an enormous hardware infrastructure buildout before its potential as a software platform could be realized.

Someone needs to build the full-stack infrastructure for Bitcoin, from silicon to software. Backed by Andreessen Horowitz and Peter Thiel, that someone is us.
