Yup, you are going to have to be into bitcoin like a boss to get all of this:
And if you don’t, sorry, this post is not for you. Just scroll down, hit one of the DFS affiliate links, and be on your way. But, if you are a bitcoin nerd (my audience has a wide range) then buckle up, because I can’t stop thinking about this. So the crazy inventor guy, @rdbell on the tweeter, the “lone nut” if you will, deserves some first followers. For those that haven’t been following the secure bitcoin hardware wallet space, Trezor is the first entry of any significance. I trust the developers (very early bitcoin fanatics) and believe this type of technology furthers bitcoin adoption – most bitcoin barons I speak to are very concerned with security of their private keys. Many ways exist to securely store a string of characters, and you will often trade convenience for safety. Ok so the above video displays a proof of concept, not a product ready to ship. IMO you could take this in a few different directions. First, what if you could plug a Trezor into this thing that would be 1x Pi, 1x camera, and 1x screen, all in some cool small form factor? IMO making a Trezor spendable would be tits+. I can tell @rdbell is concerned with having one dedicated device do all the signing, so why not use a Trezor? I understand the desire to keep a dedicated device for signing – to create an airgap between the evil internets and your precious private keys – but IMO the 2x Pi concept is a little goofy. IMO make a 1x Pi device that could optionally work with the Trezor. Many users will want a trusted hardware bitcoin wallet, but won’t be so nitty as to need a separate device for signing. Do whatever the Trezor does to keep keys safe, then add a screen and camera to it. If the project that is Bitcoin continues to grow, there will be a large demand for a secure, small, sexy-looking, spendable hardware bitcoin wallet. I can’t stop thinking about it.
