Been working on an idea for a little while, and I just published it... http://bitcoinfiresafe.com/

Basically, the idea is to make something much more secure against environmental damage than a paper wallet.  I built some custom code and have made some prototypes, and at this point, I'm ready to offer some to the public.  Given that Bitcoin Black Friday is kicking off, and we're launching at the same time, I'm offering it for a deep discount of 40% off the normal $50USD price.

If anyone has some suggestions or questions, please let me know!

Update! We created a stainless steel version!  It's melting point makes it extremely robust.


The small size and pendant hole makes it easy to store or hide using a nail or screw.

SALE TIME
Feeling like you're not getting good bang for your Bitcoin right now?  Mention "Bang25" in your order and we'll discount either model of Bitcoin Firesafe  at 25% off!  Good through April.

Cool!
But this must be made at home, otherwise it's not safe.
(I know you offer the option of protecting it with a passphrase, but this poses the risk of losing it.)

My suggestion is to either use a passphrase you're certain to not forget, or to keep it in a few places, separate from your firesafe... even on computers / cloud storage.  As long as an attacker cannot get both, your coins are secure.  This may include obfuscating the nature of the pass phrase itself.... i.e. a text file of "bad poetry" of yours that you keep in a few places.

This is pretty neat. How did you get the QR code onto that sheet of metal?

Technomancy...  Grin  Specifically a custom code generator feeding a CNC milling machine, followed by a painting process.

Nice.

Are they only offered in circular black dots? Aren't traditional QR codes in black squares?

This looks very nice.

Can you quantify the fire-safeness? At what temperature will it melt/deform?

Bitcoin Core developer [PGP] Warning: For most, coin loss is a larger risk than coin theft. A disk can die any time. Regularly back up your wallet through FileBackup Wallet to an external storage or the (encrypted!) cloud. Use a separate offline wallet for storing larger amounts.

A bit above 1200F, Classic Safe 934 begins to melt.  We're currently prototyping Classic Safe 1783 which doesn't melt until the temperature is above 2700F.  The product pages have additional details.

It's a great idea, I've been working on some similar products but in the end it always comes down to the fact that if you give someone the private key to etch/engrave/print, it's not secure. If you password protect it, it defeats the purpose somewhat of having a backup.

Hard to imagine a way around this before 3d printers take off.

You could do a much better job with one of these.

We have one in our lab at work and it makes perfect QR codes on everything from plastic to titanium.

What is the point of a QR code rather than an encrypted private key?  Less likely for someone to memorize a QR code than a long private key?

You could write down the password in a way that only you would understand, then laminate that and stuff it in a magazine in your attic. Even if someone finds the password paper (which they won't) they won't understand it anyway. And as if a common street thug who breaks into your house is even going to care about stealing this thing that looks like a paperweight.

I have access to laser cutters that can cut into aluminium and was thinking about making some private key sheets of aluminium to sell.

Why not just distribute some encrypted backups to family and mail yourself a copy? Keeping your key in a safe doesn't seem... safe, comparatively.

Cool, I hadn't thought of that. 

I have a milling machine that could put a QR code on a ceramic tile, or with the right bit, even onto a plain brick. *Thats* firesafe to a huge temperature.

Looking great now implant in inside of your wall and you're good to go. Best hiding place.
Unless you just want to display it with a small amount of BTC in it.

Yes, but a bulk of the reason behind these types of 'backups' is that in the event you're hit in the head, in a coma, or more realistically: forget your password (old age, not using the password for years, etc) you can still get your BTC. If you have to password protect it, you're still at risk for losing everything.
