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 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.

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.

True. You could just write down a password clue for yourself that isn't too complicated, for example if your name is "joe miller" write down the clue "___ miller" (obviously this is a ridiculous example, but it's just an example). It would be almost impossible to not be able to crack the password yourself, but a common thief would be at a loss.

Now yeah, if you get hit in the head and have total amnesia for the rest of your life, then you would probably forget the answers to the password clues, but I think that's such a highly unlikely scenario that it's unnecessary to plan for it.

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.
Ok nice!

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?
The QR code IS the private key, just encoded in a visual format easy to parse by machines.
It's also an option to put the 64 hex digits into a slab of metal, but to use it you'd have to type them or use (less reliable) OCR.

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.

I figured it was the key or an encrypted version of the key, but it seemed like typing them in would be less error prone than a camera trying to read the dots on steel.  Maybe I'm wrong that it's entirely readable with a camera now.

It indeed is a great idea, but how do you come around giving the private key to someone else. Should be perfect when 3d printing comes available to the big crowd!

Dude this slab reminded me of the movie Indiana Jones and the lost ark, i guess in 10-15 years we will be stealing such slabs of crypto keys from each other  Grin

With the BIP38 standard, you don't have to give your private key to anyone... you encrypt it with a passphrase that you keep, and we embed the encrypted key in metal.

Been working on an idea for a little while, and I just published it...

Neat!  I had a similar idea but yours looks way cooler.

No, there's a way around that.  It doesn't not look nearly as cool, but I didn't have to buy a laser engraver or trust the dude who operated it.

The printing press heralded the end of the Dark Ages and made the Enlightenment possible, but it took another three centuries before any country managed to put freedom of the press beyond the reach of legislators.  So it may take a while before cryptocurrencies are free of the AML-NSA-KYC surveillance plague.

That was very interesting, although admittedly a very COMPLICATED way around it. :-) But I like the idea of the user making it themselves.

more or less retired.

And, hey, you can use the leftovers for scrabble tiles if you put the scrabble point values on them.

There are some serious scrabble freaks out there who would pay good money for an etched metal set.

Yes indeed.  I get best results holding my cell phone about a foot away from the firesafe.
