Topic: [BOUNTY CLOSED] Open Source (CC) Paper Wallet Kit for safe offline coin storage - page 10. (Read 27627 times)

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!

Have not seen this thread earlier, but i also recently started designing paper wallets, for another project (I sell them preloaded through a vending machine). while doing that, I had exactly the same idea (minus the bounty   ), so thanks for starting it.

I already like the 'winning' the design very much, but the more important achievement in my eyes is the proposal of a new standard format. Since I have experience with offset and printing in general, I will look at it in more detail later.

The nice thing about a standard sheet format is obviously:
- even more designs to choose from, because now people can make designs for this new format
- easier to fork bitadress.org and other tools to support it
- once a standard format is established and supported by common tools, it really could make sense to print 1000+ sheets in offset and really good quality.

For my project, the design has to be vastly different, because my paper wallets are supposed to work as a "propaganda tool". They have very clear instructions which make it much easier for newcomers to understand bitcoin, or at least make it less abstract when explaining. When I'll have some free time I will try to 'port' my wallet design to the proposed format, for now you can look at it in form of a preview PDF or a proof-of-concept fork of bitadress.org.
Both are uploaded here: http://bitcoin.ars.is

Will discuss this with a like-minded designer at my print shop in the morning. At the very least I would be happy to assist in the production process. 24 hours will update. This post is more a placeholder than anything else.

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...

Okay, here's an updated template that includes an area for the firstbits on the note and on the stub. I've included some layers in the illustrator file just for reference as to what area is what. Designers (including me), please adjust note designs to fit into the template provided so that you have less work to do if this template ends up being the final revision. Make sure you do not move the position of the QR code or first bit boxes, since the resulting printed sheet will have the QRs in the wrong place.

aantonop: please take a look at the template, and make sure that your paper supplier will be able to make perforations along the lines where the blue guides overlap the black perforation marks in the template file.

And now, for the template...


Be aware that the area marked in red is prone to accidental tearing. Please do have your design fill the whole note but just make sure you don't put anything that's critical to your note design within that red marked area.

The entire note, stub included is 190.5mm wide and 63.5mm in height (which works out to a delicious ratio of 1:3). Ideally, your design is in 300+dpi. Feel free to bleed out a bit from the outer perforations since it'll get torn anyways.

Template file -> UPDATED, see post https://bitcointalksearch.org/topic/m.1788645

The template I posted doesn't include a space for firstbits or the full public key. Is this something we want to implement? If so, which? I can add it to the template today.

...our work...

received payment from aantonop for my design for an other competition. I made some adjustments to to colors and used the template from acorn as a base.
All comments are welcome 

(edit: URL to template removed, see new template further down in thread)

Here's a prepared AI layout. Each note should be 7.5" by 2.5", with the right-side area designated for the rip off stubs.

If there are no complaints about this template, we can use this as the base layout for the note designs. Feel free to work from this copy and contribute improvements.

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.

I can modify the design we talked about to work some space for the firstbits, and extend the bg. PM sent re: the licensing.

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.

Hrm, I'm not so sure about putting white space on perforation lines, since you'll get a bit of white on the edges of the paper. Wouldn't it look better if the background of the design went all the way to the edge?



Would the image above be an accurate description of how the tool works? You'd generate the QR codes using the tool and it'd make some sort of resulting postscript file that would be printed over the sheets you provide.

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.

Outsourcing professional paper wallets would be a fantastic idea I have wanted to inspire.  It can be done securely using a two-factor system.  Here is how it would work.

Suppose I engaged a professional printer who could do the whole thing other than prove they didn't keep the private keys (which is impossible).  Instead, I would have them create the second factor of a two-factor system.

It would sort of work like this.  I write a program to generate a bunch of random string passphrases and their corresponding "intermediate codes".  The printing company would use the same or similar program to take those intermediate codes and generate the encrypted private keys and the bitcoin addresses.  They would do all of the printing.  Those paper wallets would be perfectly usable, except that I only have the passphrases.

They deliver the paper wallets to me.  I overprint the passphrases on them, such as with an inkjet printer.  I don't know the encrypted private key because the printing company has already covered it with a scratchoff.

Once done this way, the only way the users of these paper wallets could be stolen from is if both that company and I were to have colluded to share the key material with one another.  There are a lot of ways to arrange such a production run to build confidence that such a thing were unlikely to occur (especially if there were, for example, a bitcoin-savvy go-between so I never interacted with the printing company myself).

This eBay seller have the best tamper evident security labels available so far, he also does custom prints http://myworld.ebay.com/labelogixusa

If I will get the paper sizes and quantity I can get approximate printing cost.
