Topic: Bitcoin Hardware Wallet [Last Updated: August 31st, 2013] (Read 10403 times)

Great idea for a hardware wallet. How much does it cost.

I would like to buy one of these

what would be the price range when this releases?

This is a awesome product and I heard in your video if you want to offer them for sale well I would love to put these on my webstore I also personally want one for myself and Possibly when you have them all up and done I'll buy a handful of units to see how they do in the market. Send me a PM if you would need anything from me to offer these for resale.

Oh good.  We desperately need a hardware wallet.  The Trezor needs some competition.

I am very interested in this project please let me know if interested in taking it to full production my company can help with production and funding.

Nice work , I hope a new product will come to the world in the future not far way.

That's great!
I'm definitely following this

Congratulations! Must be nice to see those test trades go through

It begins...

Today I began using the Titan on the live Bitcoin network.  From now on it will be my day-to-day wallet, and will serve as a real world test of my device and code.  So far ... I love it!  It still doesn't have a case, so holding it is a little awkward, but the feeling of empowerment and security, after all the hard work, is rewarding.  Here's the first address ever generated by the device for mainnet:

More to come...

This project looks awesome. Great work indeed!

Have you got any case designs yet for the device?

Also, would it be possible for the hardware to have a tiny cheap camera? That way you could meet someone and show a QR code from your device's screen and your new friend could scan it with his device. If it could do that I would buy multiples of them.

this looks really promising, I'd totally buy it!

Thank you for the comments!

Progress Update

• UI redesign is done, so the user interfaces looks half-way decent and user friendly.
• The touch detection code is fixed, and now touch detection is rock solid; important for the on-screen password keyboard!
• USB code is fixed, and has been rock solid since.
• Optimized the code. Transaction signing is much faster now.
• PBKDF2 iterations increased to 50,000.  This makes it difficult in the extreme for hackers to crack your wallet or backup password. For reference iOS 4 used 10,000 iterations.
• Code audited for the ~millionth time.
• A hundred other things.

First Open Source Code Released

Strong ARM

In the fullness of time, all of the code for the Bitcoin Titan project will be released publicly.  Users of such a device have a right to know what code is running on it, and Bitcoin deserves a healthy ecosystem of open source code.  Today, I am releasing the crypto library codenamed Strong ARM under the Open Source MIT license.  This library contains all of the underlying cryptographic functionality of the Bitcoin Titan project.  It's built to be lightweight, for easy auditing, and use on embedded platforms.  I built it from scratch to ensure my intimate understanding of every aspect of the Bitcoin Titan device.

For the curious souls, this crypto library is not currently built to withstand side-channel attacks, nor is it built to pass any standards like FIPS 140-2.  Those features are considered future, but non-critical improvements, within the context of the Bitcoin Titan project.


What's Next?

I will be recording and posting a new update video, to showcase the new PCB/form-factor, and UI.

More importantly, I'm looking into the case design.  This is an area I do not have much experience with; I'm open to suggestions/help here.  The case will certainly need to be custom to fit the unique form-factor.  Hopefully there are some useful services out there to assist in designing and manufacturing the case.

this is a cool project. I wanted to make one of these for a while

Sexy.

Drooool. 

Nice work, keep it up!

Excellent project. An important development needed to take Bitcoin mainstream.

June 25th, 2013: First Board Spin Working

---

The first board spin for this project has been assembled and tested, and is working beautifully.  Previously I was prototyping the Bitcoin Titan using existing development kits and other components.  This moves it to a custom PCB; no more wires sprawling everywhere!


The board itself



With the screen attached and running



In case you're wondering, those pins poking out the top and bottom are only for development and aren't normally attached.

The above picture also shows off part of the UI redesign.  Once the UI redesign is finished I'll release another demo video.

Cant wait to get my hands on one of these.

Adding NFC would be a nice touch. Hold the Titan to the back of a smartphone to make payments.
Having had bitcoins stolen from my Android, I'm waiting for something like this.
