I’d like to announce a side project we’ve been working called BitKey. The idea was to see if we could use the TurnKey development tools to create a self-contained read-only CD/USB stick with everything you need to perform highly secure air-gapped Bitcoin transactions.

Liraz and I usually have our hands full developing TurnKey, but we’ve been super enthusiastic fans of Bitcoin from early on. After going to our first local Bitcoin meetup we discovered the elephant in the room was that there was no easy way to perform Bitcoin transactions with adequate security and by that I mean that your wallet’s private keys live on an air-gapped system physically disconnected from the Internet.

People who didn’t know enough to be paranoid were making themselves easy targets to Bitcoin stealing malware, browser man-in-the-middle attacks and a whole zoo of attacks that were old school a decade ago, while the more cautious, security-minded folks seemed to be reinventing the wheel and coming up with various cruel and unusual ad-hoc solutions such as booting from a Live Ubuntu CD offline and pointing their browser at a copy of bitaddress to create a simple paper wallet.

We realized we could come up with something better, that we would want to use ourselves, and that others might be interested in as well.

How does BitKey relate to TurnKey?

Well, it does and it doesn’t. Necessity is the mother of invention and BitKey started out life as just another itch which we happened to have the means (TKLDev) of scratching. Since it doesn’t fit the mold we’re not sure yet whether it makes sense for this to be an official part of TurnKey or its own thing.

For now, BitKey is a side project that leverages TurnKey’s open source build infrastructure – but we thought that its existence and its usage of TKLDev might make for an interesting post. 

The project has its own website: bitkey.io. You can find the source on GitHub. Check it out and tell us what you think.
