Cut a wound in your arm down to the bone and make notches on the bone instead of copper wire.
When the wound heals, these notches might be visible on an x-ray machine.
This might be a good option for an apocalypse. You would be able to fashion your own x-ray machine using parts from old microwaves.

What a nonsense!

Oh, wait, in fact you really might build bind of an x-ray from a microwave magneton!
Go ahead!
Post pics, you can blur out the actual code in your bone too ;-)

Let's get even more extreme...

Store it in a strand of DNA?  Then make the DNA recreate itself (I have no idea how this stuff works), and store the resulting biomatter in a container kept frozen.  Whenever you need the data, just pick a small portion of the matter out and scan the DNA.

Huh

This seems unlikely.

As I understand it, microwaves have a wavelength of between 1 millimeter and 1 meter (longer wavelength than visible light). x-rays have a wavelength between 10 nanometers and 0.01 nanometers (shorter than visible light).  Microwaves mostly tend to be absorbed by the body resulting in a build up of heat.  X-rays mostly tend to pass through a body allowing an image to be captured on a film placed on the opposite side (and not building up much heat). I doubt you could fashion an x-ray machine from a microwave anymore than you could cook your food with an x-ray machine.

More energy needed for the higher wavelength of x-rays. You can make x-rays in a similar fashion to how a microwave works. ie by smashing electrons against a metal target.
Just need to up the potential used in your accelerator.
Do this by altering the coil windings or using two transformers etc. Just make sure your rectifier can handle the voltage increase.

A cathode ray TV might make more sense actually since the voltages are already alot higher.

Think a microwave is only about 2000 volts. A TV might be like 20,000 v I guess. In fact TV's have leaded glass in their screen for this reason. It can be dodgy to turn up the voltage too high when adjusting things inside due to x-ray dangers.

Hiding your bitcoin internally would keep it from the man. A laser could be used to burn the code into your retina!

Dude.  That is NOT how a magnetron works.  Magnetrons are oscillators, not accelerators.  And the frequency is controlled by the geometry of the resonant cavities, not the voltage.  If you increase the gate voltage, you might kill yourself, but you won't get x-rays.

Shut up before someone gets hurt.

The part about cathode ray tubes was correct.

If you ever get your hands on a schematic for a CRT display you'll find marked components for X-ray protection. They keep the voltage in the flyback transformer from exceeding a value which could produce X-rays.

Engrave a piece of metal If you are planning to store a paper wallet for a long time and in the outdoors, you should just engrave a piece of metal. You can do it at the mall (Fast Fix) for a couple bucks. It will cost more than the little canister, but it will do a better job than writing it on a piece of paper. You could even put your engraved metal in the canister.

Simple as that. I'm not sure you need an x-ray machine.

The smartest thing to do is to engrave the private key on the lens inn your eye. That way you can always see it. Since Im into AltCoins I have a huge list of priv keys so I had to dedicated my left eyeye for this. But its pretty safe. Will never in my life use a retina scanner though. Also since priv key is so dangerous if other see it, nowadays I only use the public key.

Edit: on a more serious note I guess the priv key isis best stored, engraved in a durable material duch as metal or stone. If metal starts to corrode, just make a new one. Dont engrave inn goöd or silver though because most people will see another type of value in those.

why not select one aribtray transaction from the blockchain .. maybe the first you have ever done using your first BTCs ... selected the last 60 letters of the transaction id .. run  sha256 and/or other hash over it an use the result as privkey .. .. that way you can always get you privkey aslong as the block chain exists. .. if it seases to exist, you coins are gone too :-)

I like that cointainer...... wait.. I am going to market those and call them that coin-tainers! ... Okay, I said it first, if you wish to use the name, you can use it for free as long as you mention me. But you can also tip me a royalty. (or you could care less and just use it anyway, that would be sad; unless you pretend you never heard of it from here.)

Why don't you just write it on papyrus paper using carbon soot from an olive oil lamp as ink. Then put it in a clay jar and store it in a cave. I hear that will last for a couple of thousand years.

I will be offering Bitcoin Private keys laser engraved in diamonds pretty soon. It's a little bit more complicated then originally expected so there are a few things to work out still, but my service is coming. :-)

more or less retired.
