In this talk, Andreas looks at how the ethos of the free & open-source software movement was vital to Bitcoin's success and explains why it is the open blockchains that truly matter in building a borderless, censorship-resistant internet of money. With applications that are open-source, open-access, and built through permissionless innovation at the edge.
