“Dark Wallet is a browser app for bitcoin payments that uses both encryption and CoinJoin technology. CoinJoin essentially mixes multiple bitcoin transactions, selected at random, as one transfer of funds and conceals the original payers. Dark Wallet offers anonymous transactions by default. The political orientation of Dark Wallet’s backers unSystem attracted attention to the app when it was launched on the Indiegogo crowdfunding website, where it raised more than $52,000 last December. ‘Bitcoin is the next battle ground in the fight against supranational political domination,’ wrote the backers, including Cody Wilson, known for creating the world’s first 3D-printed gun.”
