A private key is 256bits long. You don't need 25GBytes of storage to store it. A sheet of paper and a pen are all you need.

Emboss the 256bit number on a strip of stainless steel using a tapewriter.  End of Problem.

No need for computer or digital storage for a simple 64 place hexadecimal number.

Very cool!  Thanks for your post!

Wow, great idea here too.  Thanks.

Why i like some simple and yet applicable approach. Sometimes a bunch of wording like for example the seeds from electrum may not mean anything to a person even if they found out about it. Have it embossed on arts and pictures or even steel plates that lasts very long so that way they wont even suspect anything. they might just thought it is just part of other things not related to bitcoin.

Ha.. very clever idea but people who visit the house might ask why you have written random 12 words on this painting? :D

AH, but mDisc is very expensive & you need special hardware to write any files to mDisc
But, you can store your other precious files together with your bitcoin cold storage & maybe some video games files  ;D

Lololol, 'proven' for 1,000 years? I somehow highly doubt they can 'guarantee' 1000 years...

just use different ways to store your walletS and encrypt all.

You could write your private key on a piece of paper, this can last longer than ten years.  The private key is not that large so you do not need an entire disc to store it.
A private key is 256bits long and 256 really is not that large and you could even convert it to a shorter hexadecimal number of 64 characters.  ;)

buy a dremel and drill on stainless steel plate.

stop invent dumb system to store a key ... http://www.instructables.com/id/A-Stainless-Steel-Bitcoin-Wallet/

The Dremel/Chromium thing is cool,

But I would go lower tech than that if I wanted it to last 100 Years..

Use the paper backup from Armory, that will (should) always work.

Use a Credit Card Size Plaque made of Stainless Steel.

Nail it to the underside of your house, or somewhere that no one is going to be passing regularly.
Make it somewhere you could easily describe to someone, like if you are in an ambulance.

Possibly make a wooden sleeve for it, so its not obvious, or possibly fold in half, so it can't be read by just glancing at it.

The code requires no password, so take care where you put it.

You could cryptically remove or reorganise, but to me, thats asking for trouble.

And obviously TEST THE RESTORE before putting it away and forgetting it.

The disc might have a 1000 year life span - but will there be a device available to read it, 1000 years from now (or even 100 years )?

Engrave the keys into gold and it'll last 10000 years easily. Probably longer than Bitcoin will exist.

Or just spend all your coins now, so you won't have to worry about storage anymore... ;)

ya.ya.yo!

Just laminate the paper wallet.  That will last hundreds of years.  That plastic will more than preserve the paper. 

any disk is not good thing easy to scrape
paper is always good but can be lost or something else.
Laminating is good choice always, but engraving to some gold or something else is bad. You may sell that engraved gold later cuz you need cash  ;D

anyway to many ways to preserve something you can always dig hole and put coffin in hole and make treasure map.  :D

Engrave them into these. If someone wants to take them from you, then just give it to them.  ;D

This would not work very well. Although it would stop an attack from gaining access to your private keys, it would also prevent you have having access to them as well, which defeats the point.

Your ideal solution would be something that cannot be easily destroyed and that cannot easily be 'hacked' by an attacker

Well even though this is a neat thing that I did not know about, it is not the best way to store your wallet.
I'll still say that the best thing (or better) that you could do is engrave the private key onto a piece of steel or something similar. The proceed by smashing up your wall/floor putting it inside and fixing it back up.  :)

A thousand years. I wouldn't be able to access the content of a BR disc even today, let alone in 1000 years when I'm all wrinkled and senile. :D

Keep a backup magazine.

You will have to engrave twice on loaded and backup magazine.

PS Hope you dont have load off ammo  ;D

I think I will try this.

If, in 1000 years, I cannot get my bitcoins...I am coming after you OP.

This is exactly why the OP is not relevant to users needing to protect their private keys. 1,000 years is much longer then the necessary lifespan of your wallet backups.

IMO it is a necessary practice to periodically test your backups to make sure you are still able to access all of your private keys, and at such time you can replace the media that you are using to backup your wallets. If you simply make a backup and forget about it for even one year then you will have the possibility that you will not have access to your money, but you would be operating under the assumption that you did the entire time

I would agree with this. If you are trying to find something that can store your private keys safely for a thousand years then you are doing it incorrectly.

If you are not testing your backups (and re-backing up when you run these tests) then you are running the risk that your backups are corrupted and you could end up agreeing to spend money that you don't have access to

proven to last 1000 years..

so back in the year 1014 (52 years before the battle of hastings) someone invented a stone based circular disk that could be read in DVD players..............

hmmmmmmm

well i can bend a disk and snap the thin layer of slate in the middle.. takes only 2 seconds....

i wonder if M-Disk will guarantee the value of the contents if lost., id love to see my claim if i lost my bitcoin priv keys due to cracking the stone layer

i bet the manufacturer spent years banging his head against a brick wall for a permanent solution to data storage..

yea kinda permanent, but definitely not indestructible

Aren't USB devices much better than discs?

Discs tend to scratch often and lose data. While you can store data on USB drives for much longer and you can keep transferring data to newer USB devices every 10 years or so.

Any support could be damaged, paper, usb drive, disc... So you need to make backups, to place them safely in different places and to check the state of the backup support regularly.
