If there’s ever any doubt that we’re currently living in a cyberpunk world, then the OpenDime (http://OpenDime.com) sticks should help put that to rest. These little circuit boards can be filled up with bitcoins, and are supposed be used like disposable cred sticks from science fiction. That means you can use digital currency off-chain, and in person, like regular coins and notes. Couple that with some clever PCB design, which I’ll get to later in the video, and you can begin to see how cool this is. Thanks to CoinKite for sending the samples so I could test them out.
