This is meant for having a secure savings account without having to be an expert in computer security. It's safe and reliable. You protect your key more in an old school way in the "real world" as apposed to "digital space".

This app generates: Bitcoin address along with it's matching secret private key that you can use in the future to "unlock" the BTC. Until it's stored on a computer it's safe from online threats because it has never been online. It's like generating a new address but in an isolated environment. A "clean room" if you will. You then import the key when you want to spend it.

1. Get a Live Linux CD ISO image. Ubuntu is probably the easiest to use.
Can get at: http://www.ubuntu.com/download/ubuntu/download

2. Download BOTG (Bitcoin-Off-The-Grid) at: http://www.bitlotto.com/botg0.1.1.tar.gz
MD5: da7b36c1fd22d44cc62dd76f9e1aa072
(It's just a script. Source code can be read if wanted - Eventually, some Bitcoin specific distributions may include it)

3. Copy botg0.1.1.tar.gz onto a USB stick

4. Burn ISO image and leave CD in computer tray, then unplug computer from Internet

5. Reboot computer

6. Once the Live CD is fully booted insert USB stick

7. A window will probably open showing what's on the USB stick. If it doesn't, somewhere on the menu bar should be an icon to open USB stick.

8. Double click botg0.1.1.tar.gz and it will open. Click extract. Extract to home folder. (It will probably have a house icon)

9. Go back to file browser and click the "Home" button.

10. Double click botg.sh and select "Run In Terminal" OR Open Terminal program and type: ./botg.sh

11. Write down private key to unlock Bitcoin address along with the matching Bitcoin address

12. Reboot

13. THAT'S IT!


The address you record at the end will be the address you send BTC to. Because it was run off of a Live CD, no traces of the keys will be on your computer. It can't spread the key anywhere because there is no Internet. Because it was a Live CD, no operating system viruses will be able to spy on you while you are making the key. Not even a hardware keylogger would work for you aren't ever typing the key out! When you reboot everything is cleared and *nothing is left on the computer*. There is nothing to backup. Nothing to encrypt or safely make sure it's somewhere on a computer. All you need to is to keep the piece of paper safe. Instead of viruses, your risk will be someone finding that paper or it getting destroyed. Just be sure to think about what would happen if your house burned down or you hide the paper in something that could get stolen!

To access your money, right now it takes a bit of work. You currently have to patch Bitcoin to import it. It's coming down the feature pipeline and will probably show up soon. The private keys are very similar to what BitBills, casascius's paper wallet, etc are doing.

So far, I've made over 500 keys and have successfully imported them into Bitcoin without any error.


-the only risk computer wise is some type of BIOS virus - these are EXTREMELY rare. -if you have a small fortune and the tiniest risk is unacceptable, you could buy a brand new, cheap computer - run program - then destroy computer so it never goes online again - BUT that's kind of extreme!! LOL.

Game change....

It's a little experiment for testing BOTG (Bitcoin Off-The-Grid).
https://forum.bitcoin.org/index.php?topic=23081.0

For testing purposes the script does not need to be run on a Live CD -it's only a tiny amount of BTC- any popular current Linux distribution should be able to handle it. This will help test the algorithms.

What is does is:
-creates a secure address along with a key by which you can get your money back
-nothing is saved on the computer if it's done using a live CD - all the information to get Bitcoin is "Off-The-Grid" -no internet risks and no way anyone else can know the key!!
-if the script is run on a popular live CD it's immune to viruses, spyware, malware, and keyloggers, etc.
-source code can be read to eliminate doubt about what the script does and since there is no internet, nothing can be shared with another party
-the only method of getting the money back is using the key you manually wrote down -unless some hardware was recording your computer or a camera was recording you, baring having someone take the piece of paper from you, no one can get your BTC

Tip: Using blockexplorer.com can help to see if the BTC is still in that address or not.

To help test this I'm just giving the money away....

To get:
-import private key using sipa's import key function
-re-send the BTC to another address before anyone else claims it (this is only required because many people know the private key - in real life usage only one person will have the key)

I kind of want this tested so I have a really simple way to VERY safely store BTC with no chance of viruses, malware, etc taking it.

So if an address contains BTC take it! casascius- you can take some. LOL. Just leave a bit for the experimenter!

Special thanks to 'grondilu' and 'unk' ! I pretty much merged their commands/scripts together to create this one! Donate to them if you want to show thanks!

This script is intended to be added to any live CD so that all a user has to do is type:

./botg.sh

A tiny little script that uses openssl to create a private key along with a matching Bitcoin address. When run off of a Live CD environment, a very safe location for storing BTC can be created. Running on a Live CD with no Internet ensures no virus or malware can get the private key. The script will create a private key and present it in two formats: Hex and Base58. Either format can be used to access the matching Bitcoin address and helps provide redundancy in case one is copied down wrong. After copying down the keys and the matching Bitcoin address the user is advised to reboot the computer. Keeping the key "off-the-grid" or off any computer means no viruses or computer security lapses will jeopardize your BTC. No backups or encryption is needed. Any money you send to the matching Bitcoin address will be safe. The only way to steal the BTC would be to steal the key directly off of where it is written down. Therefore, it's best to keep the paper somewhere safe where it can't get destroyed or stolen.

Other uses could be:
-pre-loaded cards/tickets that are redeemable
-sending BTC when you are not sure who is going to receive it such as geo cache locations
-scratch cards or draws that are done at parties where everyone gets tickets with unknown amounts
-give BTC to someone and you don't know their Bitcoin address

Script has been tested a lot. Personally I have created over 500 keys and then imported them into Bitcoin to see if they were valid. All worked perfectly!

I'll update this post as the script develops and suggestions/improvements are made.

BOTG v.0.1.1

This creates a file data.pem in RAM. DO NOT save anything onto disk. Reboot the computer. Do not use with a Live CD set up to automatically save stuff on the hard drive.

Changelog:
0.0.2 -add part to ensure that entropy is good enough on live cd, encode hex to base58 as well, add note about having key that begins with 00, remove all caps!
0.0.3 -remake key if it's not exactly 64
0.1.0 -improve operation, and make it pretty.
0.1.1 -add pause at end in case it's run in a gui so it doesn't close

I really believe this will be very popular! It will be a very safe way for people to use Bitcoin even if their computer is full of viruses and they aren't sure how to really use computers!!

Why?
-less worries about viruses or malware
-very safe
-simple without knowing how to use linux or safely encrypt wallet - no command line!
-unencrypted wallet never touches hard drive
-blockchain doesn't have to be re-downloaded every time the user boots into the live CD
-would only be about a 30 MB download that the user burns onto CD


Here's what the user would see:

-Enter CD and reboot computer
-Loads automatically into Tiny Core Linux and user is greeted with a message:
"Now insert USB stick used previously with this software or insert a new USB stick with at least xxx MB free space. If this is the first time running Bitcoin here it may take some time to download the entire blockchain."
-User inserts USB stick
-Message says "USB stick found. Do not remove until advised it is safe to do so!"
-After USB stick is in it prompts for password to open wallet if needed. (If encrypted wallet found)
-A prompt is shown asking if BitLive should try connecting to the internet. Only connect to internet if the answer is yes.
-Bitcoin is launched
-The only icons on the screen is "Save Wallet and Shutdown" and "Addresses"
-When "Addresses" is clicked it prompts the user that "If you don't want to manually write down Bitcoin addresses, just create a text file called "addresses.txt" in the BitLive folder on the USB stick and it will be opened here. Otherwise, the file will be created now and you can edit it at any time in other operating systems just by editing the file in a text editor. This text file is not encrypted." Opens file with a text editor. Any type of notes or addresses can be put in it. This allows user to copy and paste addresses if wanted.
-When user clicks "save wallet and shutdown", Bitcoin is closed if needed and the user is prompted for a password they would like to use to encrypt their wallet.  Advice is given on how to pick a good password. (If password was needed to open a wallet it doesn't ask for it again but asks if they want to change it. Also mentions that old copies of the wallet with the old password can still be on the USB stick.)
-Once password is entered twice it informs the user to make backups of the USB stick and copy it's contents to multiple safe locations. Also tells the user they can remove USB stick. User clicks OK and system shuts down.

Technical:
-open source with all alterations to Tiny Core Linux documented so anyone can create the same product manually if wanted
-Tiny Core Linux allows for a 20 MB + Bitcoin + Gtk (needed for GUI) + GPG = about a 30 MB total ISO image.
-only connects to internet if the user says it's ok
-When it loads it prompts the user with the message and a script is watching for a USB stick to be inserted. It's automatically mounted.
-If it doesn't have a "BitLive" folder one is created. If it does, the latest encrypted wallet is found.
-GPG is used for all the encrypted -symmetric encryption
-Bitcoin is loaded with the "-datadir" being the USB stick folder. A symmlink is made pointing to wallet.dat on the home folder. The unencrypted wallet goes into the home folder. This will allow the blockchain to be read off of the USB stick AND the wallet.dat will never exist on the USB stick in an unencrypted form!
-the shutdown button will make sure bitcoin is closed and re-encrypt the wallet.dat at the home folder and put it on USB stick. Perhaps naming it wallet03282011.dat.gpg will allow the date to be part of the filename so the user can easily tell the age the encrypted copy was made.
-to create backups all the user has to do is back up the "BitLive" folder. The wallet files are all encrypted so it's safe to copy the whole folder

It would be super easy to use! AND safe!

I don't know about others but I'd love having something simple like this. It would help people who aren't really computer literate use Bitcoin safely.

Found it kind of odd as I try pretty hard to stay on topic, provide helpful posts, and talk with other lottery guys...
we'd at least get a warning right?

I'm worried that a few bad people are making more and more restrictions for everyone come out and it's hurting those who are following the rules..

Are you sure we can't restrict pm for newbies, and where they post and how often, but have people who have been around for awhile not be limited?

I like linuxcoin but it's a little much for the newbie I think. It seems to be targeted for miners.
Using a live linux CD is great for making a safe wallet. I was hoping that we could have something that was SUPER simple and small.

It's been a while since I've shell scripted and played with Tiny Core Linux but I'm certain users who have linux skills would be able to remaster a live cd that works pretty easily

Here's kind of what I was thinking
-tiny core linux as a base -that means the TOTAL size of the download once we add bitcoin/gtk/gpg will be about a 30MB iso!
-everything removed except a file browser/disk mounter/pgp/and bitcoin of course
-One icon  "Create wallet" - this will load bitcoin and create wallet if one isn't there. If there is one there already tell the user
-One icon  "Encrypt/Backup wallet" - loads a script that reminds user to use the create wallet link first and close bitcoin first and hit enter - it then uses gpg symmetric encryption to encrypt wallet, once done the user is told to insert usb stick, script watches for usb device and mounts it and copies the encrypted file to the stick. Then tells the user that the encrypted file is now on the usb stick
-Another icon that says "Load a wallet" - script asks user to enter usb stick containing encrypted wallet, script watches for usb device and mounts it, script then asks for what the file is called and finds it, and copies it to the .bitcoin folder, if it's encrypted the user is prompted for password if pgp encrypted, perhaps even scan the usb stick for a copy of the blockchain and copy it too so the user doesn't have to re download the whole thing, once done bitcoin is started.

Just thinking out loud. Would people like something that is super simple and a small download that is just for creating wallets and loading bitcoin. It would probably be about a 30 MB download instead of 600 MB or so and all the user would have to do is burn an iso and boot, and click a few icons.

I'd try doing it myself but I haven't scripted in a LONG time!

-edit: it would actually be easy to make the cd useful for being used all the time - just copy the whole .bitcoin directory to a usb stick making sure the wallet file is encrypted. Then each time the user goes in they enter usb stick and use bitcoin safely. Reboot and there are done. Very little risk.

Some people are doing it and it is confusing 
Scammers will like it because they keep the post count but can use a new identity. The only way to check is to see their old posts and try remembering who it was.

Both pretty much just ask for money and say wait and see who the winner is! Yikes! Nothing can be checked and I don't see contact info. Avoid unless you feel charitable to scammers.

Maybe not as complicated setup as Truecrypt but I think keyfiles are a must for better security. It would make brute forcing a wallet WAY harder if the attacker doesn't know what file(s) you use as keyfiles. Generating a keyfile would be a nice feature too. Bitcoin would have to remind the user though that the keyfile must be backed up and kept somewhere safe for if you lose the keyfile you can't open the wallet.

Anyone else use keyfiles elsewhere?
I don't know the details of how it would be implemented but couldn't bitcoin read the disk at random intervals (not too often to notice performance change) and access a file or two just to trick malware. That way if there is malware they won't be able to know when the actual keyfile is used?

Can someone please make one! I think it could be very popular method of communication. I'd do it, but I need a cell phone to register the group! Could I be admin too if you do? Somewhere were communication can happen in a non forum site setting.

Advantages:
-FAST!
-don't have to use forum software but can use web interface or email client
-Can handle tons of users
-can have links and other stuff
-Fast!

BitLotto is going global!

Anyone who translates the directions at the front page along with the details page will get the ad spot on that language page for one year. You can use it for yourself or sell the spot to someone else.

-it can't be a massive image. Within reason, it has to be a regular size banner.
-operationfabulous ads ok, just send me the ad code
-*it may be necessary to occasionally contact you in case small changes are needed or a user has a question*
-imgur.com links preferred for banner so I don't have to host them and not worry about slow loading ads
-no machine translations -fluent speakers only please!
-if I get complaints that it does not match or it's obviously a machine translation the deal is void
-you get the SOLE ad spot for that language! -no porn,illegal content,gambling ok of course but not competing lotteries!

-German, French, Spanish, Estonian are taken until I contact those who did part of it already for free. I'll reply here if they don't want to do it.

If you want to do a language just post it here so we do not have multiple people doing the same thing.

PS. So far the jackpot for July 6 is over 30 BTC or about 600 USD.

Any translators see: https://forum.bitcoin.org/index.php?topic=17521.0

I know for myself, I'm slower to spend BTC knowing the value increases with time. (So far) I'm always thinking: Do I need it? Can it wait? I do spend, but more conservatively.
Whereas, with cash, it seems like when I have it, I spend it. I know that with time it's value will get less and less and so I'm more motivated to get rid of it without thinking too much.
So perhaps a currency that grows in value will slow down wasteful spending? (I don't really know much about economics but it seems like quite a few here do, so I was hoping for some thoughts!)

Bitcoin 0.3.21 with Ubuntu 10.10
When I close it from terminal I get:

It doesn't really seem to have any effect with what I'm doing but thought I'd mention it just in case...

I was just playing around and created:

http://groups.yahoo.com/group/bitcoinmining

I think it would be kind of useful.
-has web interface
-people can use email to interact
-files/photo stuff
-archives
-database tool and links
-should be pretty reliable host
-helps traffic here be more manageable
I'm sure most are familiar with yahoo/google groups though.

If people want to use it, I'd make some of you mods and kind of give up the group for others to take over.

Good idea or no?

Next draw is July 6 with tickets costing 0.25 BTC each!
See bitlotto.com for details.

[Bitcoin software running on your own computer]

Using value of 8.8 USD per BTC.
See www.bitlotto.com if you want to enter.

Just remember:
-use Bitcoin software running on your own computer to enter only! Don't use an Ewallet!
-price is 1 BTC per ticket (don't sent more than that per transaction, next draw will be 0.25 BTC)
-payment has to be in a block BEFORE the first block appears with date after 00:00:00 UTC of the 1st
-backup your wallet to ensure you can get the winnings if you win

Has got me wondering. For those in the know, would this be the largest in USD value prize ever in a Bitcoin lottery? (I know TAABL had bigger BTC prizes but BTC wasn't worth as much before...)

AFTER June 1 draw ALL tickets are now 0.25 BTC EACH!!
JUNE 1 DRAW IS STILL 1 BTC! Anyone who paid 1 BTC or accidentally pays 1 BTC for later draws for the next while will get refunded the difference. I tried avoiding it, but Bitcoin value is just crazy! (In a good way) I started this lottery expecting people to pay about 1 USD per ticket and in a very short time tickets were about 8 USD. Of course the winnings were worth more but at the expense of less players playing. Even with cheaper tickets BitLotto should be able to have a growing jackpot each month as more people are willing to play. Hopefully everyone is pleased with my choice. Thank you for understanding my need to change the price...

I've also added operation fabulous to my site for those who want to target the Bitcoin gambling demographic.

So far the June 1 jackpot is: 84 BTC or about 730 USD!!
