The inside story of two crypto-anarchists and their quest to create ungovernable weapons, untouchable black markets, and untraceable money. ... Concerns about the police are justified for Wilson and Taaki, who have dedicated their careers to building some of the most controversial software ever offered to the public. Wilson gained notoriety last year as the creator of the world’s first fully 3D-printable gun, a set of CAD files known as the Liberator that anyone can download and print in the privacy of their home to create a working, lethal firearm. Taaki and his collaborators recently unveiled a prototype for a decentralized online marketplace, known as DarkMarket, that’s designed to be impervious to shutdown by the feds. ... The programming provocation they released a few hours ago is called Dark Wallet, a piece of software designed to allow untraceable, anonymous online payments using the cryptocurrency bitcoin. Taaki and Wilson see in bitcoin’s stateless transactions the potential for a new economy that fulfills the crypto-anarchist dream of truly uncontrollable money. ... “I believe in the hacker ethic. Empower the small guy, privacy and anonymity, mistrust authority, promote decentralized alternatives, freedom of information,” he says. “These are good principles. The individual against power.” ... According to a study published in May by the nonprofit Digital Citizens Alliance, more than 40,000 mostly illegal products are now listed for sale on the obscured corner of the Internet known as the dark web, more than twice as many as before the Silk Road bust. ... Wilson and Taaki intend Dark Wallet to be the most user-friendly method yet to spend bitcoins under the cover of anonymity’s shadow—without switching to a niche alternative coin or trusting any shady middleman.
