As bitcoin continues to climb in value, its security flaws become increasingly apparent and important. The nightmare is waking up one morning to discover you were hacked and your five-, six-, or seven-figure savings are gone forever.

This reveals one of the major usability flaws with bitcoin today — the impossibility of trusting your wealth to stay, well, your wealth, and how that is a major roadblock to mainstream adoption. The object of this exercise is to make a laptop that has never connected, nor will ever connect to the Internet — and have that laptop be the so-called cold storage of the keys that are used to send coins from our large wallets. We will still be able to see the wallet from our online workstation, but in order to send any money from it, we will need to do so on the offline laptop, the cold storage.

Your first step is to take an old laptop and kill its wi-fi. We want to make sure that this particular computer can never, ever, again connect to the Internet — even accidentally, particularly not accidentally. It has to be permanently offline.

We are going to move files back and forth to it using a USB stick. Mine is almost a decade old. Download Ubuntu Did you kill wi-fi on the laptop yet? Seriously, the one single purpose of this laptop is to never ever have been connected to the Internet, so take the time for peace of mind and kill that wi-fi. With that done, install Ubuntu The one key step you must make sure to do here is to choose full-disk encryption.

You do that in the partitioning part of the install sequence: make sure to pick the installation option named Guided — Use entire disk and set up encrypted LVM. Choose a strong password , obviously. Use five or six words if you want to be super-paranoid. Ok, so you have a freshly-installed offline laptop with bit Ubuntu The solution is named apt-offline , which is a utility that enables an offline computer to use a secondary, online computer to fetch its packages from the Internet. Move the USB stick to the laptop, open a Terminal, and run.

This will enable us to install packages using the USB stick as a relay to the Internet, going through the online workstation. On the offline laptop, with the USB stick still inserted,. Yes, we need apt-offline on the online workstation as well! This fetches the needed files and puts them on the stick.

Expect a few fails in bright red. Return the stick to the offline laptop, and run. Move the stick to the online workstation:. Armory is an advanced bitcoin wallet that allows for offline storage, so-called cold storage. Still on the offline laptop:. The two dashes in the command are important, they indicate the end of the package list initiated by —install-packages. Move the stick back to the offline laptop. If everything went well, you will see!!! Armory successfully installed!!!

Start Armory on the offline machine. Create your first wallet. Armory will prompt you to back up the wallet. Close all distracting Armory dialogs and messages so that you come back to the main screen, and select your newly-created wallet. Create a watching-only copy and save the file to the USB stick. In the dialog that follows, we have the option of more advanced backup types. A fragmented backup means that you print five pieces of paper, and need three of them to restore the backup, any three.

Or two out of three. Or nine out of eleven. The numbers are up to you. Without this option, the PDF contains your entire wallet unencrypted, and since the PDF file will be touching the online workstation and printer while printing it, your unencrypted wallet will be on an online computer without this option — exposing it to hacks.

The offline Armory will present you with a Secure Print code on-screen, to be copied by hand to the individual fragment printouts. Copy the SecurePrint code by hand to a separate piece of paper for now. Keep the note with the Secure Print code beside the printouts for now. The only practical difference is whether its funds are listed as yours in the financial summary. After that, Armory — the online version — will want to install the reference bitcoin client as its back-end and synchronize with the bitcoin network.

That will take quite a while, as it loads the entire blockchain. All the addresses that the wallet will ever contain are embedded in the initial backup. This restore process is a confidence and security exercise. In case of disaster, you want first-hand knowledge that the backup of your many-figures-wallet works, and you want to have used the backup once before so you know how to do it. Wipe the disk completely. Install apt-offline and get the packages, then install Armory again, repeating the above steps.

Type the backup data from as many fragments as needed, enter the Secure Print code, and click Restore. While this can be a comfort in itself if you forget the password, that also means that the problem shifts somewhat from protecting your online computer, to protecting a set of pieces of paper. The wallet should restore fine. At this point, the online workstation is probably still synchronizing with the bitcoin network.

You may want to take a break here and go for lunch or so. Wait until six confirmations have passed, so we can send the money back somewhere. Remember now, these are coins in cold storage. The originally created wallet was simulated to be destroyed as we wiped and reinstalled the laptop. Move the USB stick to the offline laptop. Enter the wallet passphrase. The offline Armory will remove the unsigned transaction file on the USB stick and replace it with a signed transaction file.

Transaction details will display. You can verify in the blockchain that the transaction has been executed, and you know by your actions that it was signed on the offline computer, which has no connection whatsover to the Internet, nor will ever have one. Just one important step remains. Just remember that having observed enough fragments in combination with the Secure Print code is enough to gain access to all your wealth in cold storage without further safeguards or passwords, and devise your backup strategy from there.

There are several other distros that are better or at least equally newbie friendly as Ubuntu. The answer is obvious: Debian. Nice tutorial.

I have but one issue with bitcoins: they are not practical for the average Joe. I mean, look at the level of knowledge you need just to go through this article. I wonder if there are ways to make it more user friendly so it can go mainstream without giving up the security? This has been one of my observations from the beginning, that new technologies take about ten years to reach a level where usability gets good enough.

My prediction of a mainstream breakthrough for bitcoin around remains. That is obviously the surest way to disable it. These days it may be included on the wifi card. Good points about wi-fi hardware. In theory, it could even be enough to uninstall and remove the wi-fi drivers, as they would have no way of reappearing on their own. It seems to me that the point of never connecting to the internet is broken when you install software downloaded from the internet anyway, especially when downloading Armory from the NSA controlled domain name amazonaws.

What you have eliminated completely, though, is the back channel. I wish I could have used apt-get for apt-offline, but alas, the package was not available. That was my first try, for the reasons you mention. The machine is offline, after all. Any such updates will have to be installed manually. Also, the fact that the machine is offline will be a mitigating factor in any security concerns.

I live in a 3rd world country and we get lots of old desktops dumped here from your part of the planet. Everything from p4s to c2qs. This particular laptop of mine had broken networking and had a bad screen on top of that, which made it useless as a production laptop for anything else but this exact purpose.

I was assuming most people reading this article would be in a similar situation. Apparently, your situation is almost the opposite — you write that you have a surplus of old desktop machines. That way you minimize the possibility of having malware on your computer. After a couple […]. The weak spot here would be me, screwing up with the instructions or losing the usb stick. Or the paper.
