[ANN] PaperCoin

[stick]

Hi all!

I would like to introduce a weekend project we did with my friend Split. PaperCoin is a website that provides a very simple way for people to print out paper offline Bitcoin wallets. Once folded, the private key is hidden inside while the address is still visible from the outside. It's a great way for introducing your friends to Bitcoin. All cryptography and PDF creation happens in Javascript in your browser and nothing is sent back to server. You can even download the source code (yes, it's open source!) and run the software locally, if you wish.

Enough babbling, go to http://papercoin.org/ and try for yourself! :-)

This is how the output page and folded wallet look like:



Feedback, ideas and patches are appreciated, of course!

Please see a similar, open source licensed effort we have in progress here:

https://bitcointalk.org/index.php?topic=155847.0;all

There may be some potential for collaboration, and we could certainly use insights, feedback and support.

Really great looking site. Who did the design for this?

His project is open source too, see the bottom of the page.

I think this is one of the best things to happen to Bitcoin yet.  I love it.

Also open source? EXCELLENT.

Plus it seems you have very good design skills for web.

Please let me know if you had a look and found the OpenPaperWallet project interesting:

Well done!

I tried to import the privat key into Blockchain wallet. But it rejects it.

Can you loose another word or two how to work with this?

Thank you!

My friend did the design.

Did you read the private code after folding the paper? Private codes start with "5".

[acf6996]

Indeed that was it. Was too lazy to cut and origami the paper... 

If you do it is obvious and works well. Only typing in the private key is a pain.

Added QR code for private key in the latest version.
