Found out about Bitbills yesterday and thought to my self what an awesome product... and now the site is gone.

I hadn't tried in a few days but am accessing the site now without issue:
  - http://bitbills.com

I just got a response from llama to a PM that I sent him a week or two ago. I assume he's still around, perhaps the site is under maintenance or a DoS.

We are continuing to work on an easy redemption tool (it will be a flash applet that uses the webcam to send the bitcoins to your address fee free).
Why Flash? My understanding is that phones can read QR-Codes without it. I hope you plan to make it a HTTPS-only function (with a proper cert)...

I assume the flash app is for desktops and laptops with webcams.

Another alternative would be to import a photo of the barcode, taken with any digital camera.

To handle counterfeiting you could create a second private key (that is not associated with coins) and put the public key in a second QRcode on the back. You can then release an open source Android/iPhone app that scans that code, creates a random nonce, sends it to bitbills.com for signing and then verifies the signature using the public key on the card. Because only you have the second private key, it's impossible to forge this. It's convenient for anyone to check the bill is legitimate using only a smartphone, so it can be done portably and quickly.

This is a good idea, and truly prevents naked counterfeits.  However, it wouldn't stop someone from buying a legitimate bitbill, then making a copy of that bitbill, but with a phoney private key.  They keep the real one, and sell the phoney.  As long as the private key is carried with the bill, with a static public key, there is no way to have 100% trust in it.

The only way I can see to securely handle transactions would be to centralize the private keys.  One way to do this would be to use your exact example, where bitbills generates a keypair that's assigned to the bitcoin keypair.  But instead of printing the QR code for the secondary public key on the card, you give users the options to simply buy bitbills in that fashion, where bitbills.com keeps the bitcoin private key, and gives the user a pdf with two QR codes, one for the bitbill public key (that they can show to prove the money is real), and one for this secondary public key (that you would keep hidden until you hand it over).

You could call this pair of public keys a 'bitnote' (a play on federal reserve note).  To use the bitnote, you just print it on a piece of paper.  When you give someone a bitnote, they use a smartphone with your open source Android/iPhone app to validate the bitnote, and then bitbills.com immediately invalidates the bitnote and generates a new bitnote, OR the user has the option of transferring the bitnote to a bitbill or a bitcoin address.  This would basically be creating a bank with a backed currency.  You can get the REAL currency (the bitbill), or you can have a note representing it.

Tried to order bitbills, but mybitcoins told me the payment was failed. Paid the exact amount to the exact address. I've tried to use the contact form on the mybitcoin site without any answer.

Does the payment gateway just suck or is this a scam? Maybe llama could consider using other payment systems (heard that others have had problems with mybitcoin too, but thought it was rare).

Placed my order, eagerly awaiting my bitbills! I think these are a pretty cool way of introducing some friends and physicalizing a virtual currency since people have a bad tendency to ignore something if it's not in their hands.

I plan of gifting some to my friends who are technically skilled and are aware of bitcoin but hesitant.

I checked out bitcoinj and built it, and I can't run the code.  The above command didn't work at all.

If I run:

java -classpath ./dist/* com.google.bitcoin.examples.PrivateKeys

it runs, but complains that slf4j classes aren't found.

Ah yeah, try:

ant build
java -classpath ./out:./lib/* ......

Sorry to hear you had such problems. As a library it's only really meant for people familiar with Java development right now. My faulty instructions don't help.

If BitCoinJ is going to be a common way to extract Bitbills we could/should just upload a simple binary with a GUI and everything included, so reclaiming them is point and click. Might be a fun project for someone - maybe BitterTea? :-) Making an all-in-one JAR with a Swing GUI isn't very hard and there are lots of tutorials on the web.

First, is there a better thread to discuss this since it's not strictly bitbills?

Now I've got things running on my MacBook, but it consistently hangs when "Chain is now 5172 blocks high" with "java.io.IOException: Socket is disconnected"

Some updates:
We still have a lot of preorders coming in, so we're continuing to work as fast as we can to ramp up production. Orders are shipping out continuously now. We hope to change from "preorders" to live "orders" later this week!
Simultaneously, we're working on the next product version. This will include several changes, including custom holograms. It's still a ways off, but start getting excited! We will keep an archive with images of all previous versions on the site.

On redemption:
I'm sorry to hear that some people are having difficulty redeeming. We will post a video soon demonstrating the process. In the meantime, some tips:
  • Use a penny to scrape off hologram residue
  • A thin layer of tape sits above the laminated qr code. If the residue remains a problem, peel off the layer of tape to reveal a clean QR code
  • Use alcohol or nail-polish remover only as a last resort. Newer Bitbills use a higher quality private key substrate resilient to chemicals, but their use won't be officially supported until the next version
  • Use a high-resolution scanner if your webcam or phone camera have problems

As mentioned in the FAQ, we are happy to buy back any sealed Bitbills for face value if you don't feel comfortable attempting redemption yourself. We are continuing to work on an easy redemption tool (it will be a flash applet that uses the webcam to send the bitcoins to your address fee free).

I'm offering large bitcoin prizes to anyone who feels like working on Bitbills tools! (this could be an Android app, iPhone app, support on your website, etc; contact me!)

I improved BitCoinJ a bit so now you can just use PrivateKeys without any modifications, like this:

java -classpath=out com.google.bitcoin.examples.PrivateKeys

Make sure you have a running copy of Bitcoin (regular C++ software) on your computer and run the above command. It should trundle along and process the block chain looking for usages of the key. Then it will send you the coins to your chosen address.


I checked out bitcoinj and built it, and I can't run the code.  The above command didn't work at all.

If I run:

java -classpath ./dist/* com.google.bitcoin.examples.PrivateKeys

it runs, but complains that slf4j classes aren't found.  If I downloaded slf4j and unpacked it, and ran:

java -classpath ./dist/*:~/src/sld4j-dir com.google.bitcoin.examples.PrivateKeys

I get all kinds of crazy errors linking to pages on the web talking about all kinds of problems with linking to multiple versions of slf4j stuff.  If I try to limit the jars I still get errors.

Did you include (or try to include) the logging stuff or do I need to configure that somehow.

Anyway, I give up on bitcoinj.  Try to download the patched client from bitbills.  That won't execute at all.  I'm presuming because it's a 64 bit build and my linux box is 32 bit?

I try to apply the patch manually, but then remember I could never get the original client to compile because something was wrong with UPNP, even though it compiled and installed.

Not complaining, just pointing out that it's been pretty hard for me to get my money.

I bought bitbills just because they're cool, but may have not thought into it too much. If I don't have a smart phone that can read a QR code, am I SOL if I want to get the money off them?

You don't need a smart phone, you can use a computer with anything that can get a digitalization image of the QR code (scanner, cam, mobile with cam...)  and a QR code parser software.

Well you would for an android app... Anyway, I just tried again and instantly scanned it.  I think my shiny silver macbook might have been interfering before.
