I agree. It looks quite professional. Nicely done!
Like it too! Nice work, well done!
I really like paper wallet art and your first verson is awesome. I hope you have the chance to make some more someday.
Oh I will definatly plan on trying my hand at a few more desings, I really like working with paper wallet layouts.
Looks nice, and I'm sure it'll look even nicer with tamper-evident holographic stickers on it, but I've honestly never really understood why people continue designing single-sided cryptocurrency wallets when you've got stuff like this trifold model, featuring a fold-over tab and obfuscating textures to make it difficult to read the private key before it's time to spend them, or my current personal favorite, the Walletgenerator style, which unlike the previous one, is designed to be printed one-sided.
Ever a tinkerer, I've put a degree of thought into what I would want in a paper wallet, inspired in part by the above examples, and a blog post by the guy who made the Casacius physical coins about how he likes to tear a wallet in half and use it as an easy way to create an IOU. Give someone the public half and they can pay you. The private half, and you can pay them.
What I'd like to see in a paper wallet(in approximate order of priority):
Fold-over design. Preferably a tri-fold or more. I'd like a wallet that, once sealed(say, via packing tape or a tamper-evident sticker), can't be spent without physically destroying the wallet, making it obvious whether a private key has been compromised(and therefore should probably be swept.) Public key outside, private key inside. At least 2 layers of paper including an obfuscation pattern between the private key and any publicly-visible portion of the wallet.
One-sided printing. I would like a paper wallet that I can print in one go, without needing to do tedious alignment checks. This is the prime reason I prefer the Walletgenerator style trifold over the Bitcoinpaperwallet style foldover.
Redunadnt public keys or integrated "business card" style accessory wallets(see the abandoned side project on Walletgenerator). Inspired by the Casacius guy, I think it would be good to be able to give half of the wallet to someone else as an IOU. Make a wallet with the public key recorded in two locations, and you can tear one off and give it to someone, and still be able to check the balance without breaking it open.
Adhesive friendliness. I recently purchased a thermal printer(arrives Tuesday) with making secure, convenient paper wallets in mind. I know a lot of this is software-side, but I think it would be neat to be able to run off adhesive labels containing the public and private keys, which can then be stuck to the wallets for assembly. This also means you wouldn't need to tie up an expensive color inkjet or even more expensive laserjet just for printing wallets. Print the wallet blanks, apply the inexpensive stickers printed with the inexpensive printer, seal them and go.
Just some thoughts on the subject.
Thermal printers adhisive can be easily ruined just by running your finger nail across it. The try folds are a good idea, I may pursue that option for the next design though I would not wan the end user to have to rely on a tamper evident label.
I mostly just use the paper wallets for my own personal cold storage, they make a less than optimal solution for exchanging cryptos.
Yeah, the longevity of thermal tape is something I'm a bit unsure about. I think I've had tons of receipts no longer be readable after a week or less.
My basic (untested) theory for a Walletgenerator-style trifold was that I would laminate-tape it shut with packing tape so that you can't read the private key without physically tearing or cutting the wallet.
And if you have much simpler tastes:
Great work, I really like the first design.
If you could do something similar in a trifold layout it would look perfect.
I also think the tamperproof holographic stickers will complement the design nicely.
Yeah I was looking at some of the folded designs. I may use one of their templates for the shape to make things easier. I'll keep you posted!
This is really amazing to see. You should be proud! That reminds me, we should start a thread about a "slogan". We ran with "rethink digital currency" as a kind of campaign to communicate the original intent of the project - what's it's all about for fresh eyes. I do wonder if we, as a community, can come up with something stronger to sit with the actual currency now that things are being created. Something that can be indefinite. I was even thinking about just a single word that can stand the test of time (Decred - something). I will think on this a bit and start a thread so we can get it going. Can't wait to physically hold these one day! What an honour to see it created like this!
How about something like collective or unanimous ilike the idea of a play on the collaborative side of things
My take on a trifold wallet layout. Yes, it's very exciting. Maybe someone can spice it up a bit?
The reason I put this together over just using the Walletgenerator style is if you fold a Walletgenerator wallet, you may notice that one side of the Private key gets 2 obfuscation patterns over it, while the other gets... zero. I held one up to the light to check, and yep, the private QR code is TOTALLY visible if it's been printed on normal printer paper.
When folded properly, the "logo" pane and public keys should be on the outside. The wallet can be sealed shut like this, with the "misc" pane being hidden inside, or it can be taped just so that the private key is inside and the logo/misc panes can be folded open, for example, if you want to put a second Public key or a ledger on the "Misc" pane.
You should be able to print 3 of these on a standard sheet of printer paper(8.5"x11" in the US, I think it's... what, A4? in Europe) and it folds down to a little under 2x3 inches.
Vector file included in case it's useful to anybody. And yes, the obfuscation patterns are totally 3-layer "polka dots" texture fills from Inkscape.
Here is one just for you based off my original. thanks for the template!!
Let me know if I need to make the two areas more obscure.
Knew you'd come through if I posted something like that. I'll try printing a couple out once my printer ink arrives(probably late next week)
I did just realize I forgot to put an amount box in there.... Sorry about that, I will update tomorrow. Let me know how it turns out.
I was actually making some tweaks(including replacing the old noise pattern with a better one), give me a minute.
That back plate is getting pretty cluttered, isn't it? I guess we do only have 2 panes that might be outside and 3 pieces of information to fit in them.
I printed some QR codes and patterns on my thermal printer, and it looks like while ortho-aligned binary noise makes it hard to read the QR code and text behind it, diagonal binary noise makes it nigh-impossible. Not sure why, there's probably a mathematical theorem out there to explain it.
On the two outward facing planes you could probably remove the darkish boxes. Also with those removed you could probably remove the panes around "Rethink Digital Currency.". The "D" at the same opacity might look pretty good centered on the noise patterns. After looking at it more the darkish boxes on the load & verify tile and the spend tile could be removed, might help with the cluttered look.
I like the "D" symbols in the patterns. I removed most of the gray boxes and it does look a lot better, but left the one in the private key area because it helps denote which regions are safe to put data in if the user is using separately-printed stickers or labels(like I plan to)
Small edit: I realized "Hey, Private keys are big. I should make some more space for that." and turned the pane for the private key sideways, like it is on Walletgenerator.
The public key might benefit from the same alteration, which would also merit turning the "notes" pane sideways... which might also help with the clutter issue.
I don't know what it is. No matter what I do with the note pane, it keeps giving me that "Late 1990s church power point slide" vibe.
That Triangle logo is also making me think "YMCA."
I'm going to stop touching it and let Freedom2Choose fix it for a bit.
Comparison to version 2.6. Definitely gone too far.
