Very nice work. Love the color schemes.

This template with multiple designs is coming along nicely. I have a feeling the April launch will include more than the 3 designs I was hoping for...

I bet once it's out there and usable, we can have all kinds of designs: modern, clean, fancy, alternative, weird, bank-like, web2.0 like.

So far, most look like "money". I would like to see some even more radical designs, I'm sure they will come.

We will have a nice little "dropdown" choice full of designs... yay!

Not necessarily...

The note is meant to have an OPTIONAL stub. You can print or not print it. Some designs will have it, others will not. The layout accomodates several different designs:

- Bill for folding (your style), print the left and mid-right boxes, leave the stub empty.
- Bill with backup, same as above, but stub with secondary keys for keeping in another location
- Wide-bill, print either the left QR and the two on the stub, or the left QR and only one of the stub QRs for a full-width note. No cut lines in that case

Basically, you have two widths to choose from (wide, or narrow), and four QR/key areas. You can mix/match any of those to print any variety of bills including your design. The cutlines and stub layout are optional and can be ignored in software for certain bill designs.

In any case, let's figure out how to make it work for several uses and markets (at least at the template, software-generator level), which will benefit everyone.

By the way, the scratch-off stickers cost less than  1 cent each, once you get to a $50 order size. Totally worth it in my mind. I'm ordering 10,000. As I said, doing this in a bulk order makes sense to get reasonable prices.

I would prefer to have both. The firstbits are meant to be larger, to easily distinguish different notes, when loading. When my app asks for note  134j5g2j6g256jg25624563456, and I have a stack of 100, I sure would like to be lookingat a big font for that.

However, I still would print the full key under the QRs, for recovery without scanning. The current design, I believe allows for both, but having a discussion between designers is exactly what I was hoping for.

eins78 welcome!

We have similar goals.

I am launching openpaperwallet.com, an open source site (and github repository) for coordinating a design, open and free graphics, instructions, software etc. All dedicated to the open paper wallet.

I will be "forking" that into a commercial bulk operation, my first print run is about 10,000 notes, of three designs, to bring the cost down and afford high quality offset, emboss, microperf die and good paper.

Once the software is tweaked, I will be able to add a new paper design with a github pull request from any designer.

The website itself will also be open source. I'm looking for CSS3/HTML5 designers to help me make a barebones multi-platform site that can be easily hosted on a variety of cloud and hosting providers.

If you want to help, please join the effort!

ON IT!

I'm meeting a real ErlangOTP *expert* (phds, patents, the whole 9)  next week who recently got interested in bitcoin. Perfect timing to introduce your code...

Yes, that's exactly what it does. You can change the frequency simply by going back to the registration page, once you've activated.

I will add some documentation and more SMS commands.

Thanks for the question!

Check out the new capability at http://btcprice.info/register.

You can select the threshold (4%-10%) that triggers an alert, the maximum frequency (max once an hour to max once/24hrs) and you will be notified whenever the BTC price moves more than your set threshold.

The system is designed and tested to scale to 100,000 subscribers, still delivering alerts to all 100,000 subscribers within 1 minute of the price change.

As always, btcprice.info still offers SMS and Voice (spoken announcer) quotes in English on BTC/USD prices on mtgox, in 5 countries and counting, for free.

Feedback and comments welcome, here or at info@btcprice.info.

Thanks!

This is incredible work acorn.

Any of the other designers have a chance to review this? Can you use it as your template?




BOUNTY AWARD

Pending final files and correct licensing for all artwork included, I think we have a winner.

Unless anyone objects, I intend to award the first place bounty to acrorn, for 5BTC. If you object, state your reasons. I will wait 24 hrs, then award.

Still two bounties left: 2.5BTC and 2.5BTC for second and third place designs. Currently Timbo and 75RTUGA are in the lead for those, pending changes to fit the template. Again, if you disagree, state it.

There will be more bounties on this...

Glad it worked.

Feedback and suggestions are welcome.

Almost done implementing automatic SMS alerts with price/% thresholds, for subscribers.

Beta testers for the automatic alert service, PM me.

If you send any SMS to one of the numbers that support it, it will auto-respond with the BTC/USD quote.
Or you can listen to the detailed quote and select 1 at the end to get an SMS too.

Added several more access numbers and SMS support

mtgox has a couple.

I believe the most low-latency API they have is the websockets API, where you subscribe to a price feed in near real time.

Thank you Timbo and acorn

I am increasing the bounty to 10BTC, for more participation

Three Winners: 5BTC for the top contribution to the project, 2.5BTC x 2 for the next two best contributions.

You're the designer, not me... Whatever you say.  


YES, exactly. Amazing and clear.

I think it would be nice if the graphic design extended to the tear-off stub, at least the background color, rather than leaving that part blank completely. That way the stubs are pretty too.

I was also thinking of printing the first 4-6 letters of the public address on the note and stub, a bit like a serial number. That would make it easier to match the stub and note to each other, or to find the correct note from a stack of dozens.

Something like:

1DkvYc somewhere on the note and the stub. If you like the idea of a larger-size number/serial on all the notes, then there should be a location for it in the template, so that the designs can incorporate it, either with a white background, or not.

Again, I am open to suggestions and ideas and would like to do this collaboratively. You seem to be totally on-track with what I was hoping.

Casacius, excellent suggestion. I think this project could easily evolve to that goal eventually. For now, I'm keeping all the key-printing and security labels in the users hands, while doing the professional-grade pretty designs and perforations at a large professional printer. But since this will be open-sourced, it will be easy to adapt it to the process you suggest for a complete noob solution with no printing for the users.

The way I look at it, you did 1.0 with the coins, bitaddress.org did 2.0, my idea is 2.5 and what you're suggesting could be 3.0 built on top of this project's code and designs!

Yes, the end-user will receive the sheets, generator code and stickers. They will print they keys and cover them at home, for max security.


The stubs can work as optional component. If you check a checkbox in the generator, it puts QR codes in the stub boxes too, otherwise it leaves them blank. If you decide to print the stub as a backup for your notes, it prints an extra copy of the private/public key QRs that are on the left.

I would include enough security stickers to cover the private keys on all the stubs, too. So, two stickers per note.

It would be used like this: Print the keys onto the sheet of notes. Separate the notes. Cover the private key on the note and also on the stub with two scratch-off stickers. Tear off the stubs. Put all the notes in an envelope in a fire proof safe. Put all the stubs in another envelope and put in a bank security deposit box, or give to a trusted relative to store in their home, or put anywhere safe that is far from the other copy.



There should be specific whitespace for the perforation lines. I will be taking this job to a professional offset printer with micro-perforation dies. They can align it down to 1/64" on color, sheet and cuts. For home-printing you will need a white buffer between notes, even if only 3-4 pixels, I think.
