Managing a subversive digital library takes courage: Julian Assange is in exile and the founders of The Pirate Bay received prison sentences. How can we design a digital library without a central administrator to attack? To meet this challenge, we'll sneak data into the Bitcoin blockchain, permanently destroy bitcoins, and build a peer-to-peer network entirely out of browsers. If we do it right, we won't be able to take the library down even if we wanted to!
