Topic: How would you like to design a bitcoin banknote? (Read 94764 times)

Designing a bank note for bitcoin should have the the QR code with the specific value mentioned in terms of satoshi. Along with the same adding the bitcoin logo makes it to be known to the common people with ease. On the whole these can be used as a limited edition, and making it printed in black color will be more apt for the same.

i would like a blue note with the current bitcoin logo in the middle, yellow of course...

Yes, why need a Paper note. We are moving towards a digital currency and its online availability is good for us and more convenient too. Why moving back to the FIAT currency characteristics. So real benefit from that in my perspective.

Bitcoin Note Can be in Golden Color with a big bold B.
It will be great to have in the physical wallet.

Well since you guys resurrected this ancient thread, I'd just like to say I wish Casascius would make coins again.

the whole concept was to make the 'naive fiat world' imagine bitcoin like bearer bonds.

i have handed out many 'notes'.. but not to use as a bank note (changing hands many times) but instead used as a bearer bond that is put in a safe place so no other people can see it.

it helps to get people to understand the paper wallet concept easier, then they dont have to worry about backing up private keys on computers all the time. because its a paper wallet.. essentially

I can't agree with you cause if bitcoin will get popularity and become a fiat, banknotes will need for people and make good design is really important.

Yeah that's right but if bitcoin needs high popularity surely the physical currency form need to exist. Also it need to be created in such a manner it can't get duplicated.

Actually i would like to design of bitcoin just like Dollar, because i really like the design of Dollar, no one can say that Dollar design is awful, i wish bitcoin will be come in note currency like a dollar, litter bit different , i think people will like it. 

I think this is worth considering especially if bitcoin's value were to rise in the next year. I also liked the idea of printing the value in bitcoins and USD, EUR, etc. as it would make it seem more accessible to the average person and probably attract some interest.

You should experiment with a real private key. The key and QR code are much bigger than the bitcoin address.

A cheque style 8.5/11 I could buy with a well designed backing and the ability for me to print my own numbers on the front, with a basic word template, and than those scratch off stickers I could apply after printed would be pretty awesome.

I held off on this change because I was having a bit of trouble producing a native Win32 build of an updated vanitygen.  I figured that out this morning...the result is here:

With this last piece in place, it took just a few changes to the generator script to produce notes with compressed addresses:

I updated my own project myself. Here is  the result.

Be sure to put a lot of pure gold threads in it. And laminate it so that the gold doesn't wear off or fall out.

It's been a while since I've touched this code, but since the moment to which you refer has arrived, I've pushed an update that redenominates my notes in mBTC:

I thought about also changing it to use compressed addresses, but that would require a fork of vanitygen (such as mine) that supports compressed addresses. 

Get something that has a lot of attention to detail.  Super micro fine print.  Also intertwine some hologram into the fabric like they do with the super sexy new $100 bills with that super cool blue strip.

Sorry for reviving this thread - given the fact that the mBTC may soon reach USD parity, I am wondering if some new bitcoin bill designs (e.g. from salfter?) are around showing mBTC denomination?

If so, I will use those for my new bitcoin vouchers (see signature) to be distributed in 2014...

I was worried that a paper wallet might be destroyed by water if it caused the ink to bleed, making the qr code and text unreadable, so I experimented.

First, I printed some paper wallets on my cheap printer. Then, I applied varying amounts of Krylon acrylic spray in different ways and dropped water on the paper.

1. 1 coat on the front and wet the front.
2. 2 coats on the front and wet the front.
3. 3 coats on the front and wet the front.
4. enough acrylic to soak the paper and wet the front.
5. 1 coat on the front and wet the back.
6. 1 coat on both sides and wet both sides
7. wet the front of unprotected paper

I allowed the paper to sit until it was dry.


Here are the results:

Unfortunately for the experiment, the ink that my printer uses (Epson DuraBrite Ultra) resists water very well. The #7 unprotected ink was mostly unaffected by water. It smeared noticeably in one area, but not enough to affect the readability.

Assuming that not all ink is so resistant, here are my other observations:

#1, #2, #3, #6 - A single coat is sufficient to prevent the water from soaking into the paper, but multiple coats make the surface of the paper shiny.

#4 - Soaking the paper with acrylic tended to reduce the contrast of the paper and cause the ink to bleed very slightly, but not enough to make it unreadable. Other inks may behave differently.

#5 - Because the ink was water resistant, it was not possible to tell if coating one side protects the ink from water on the other. I suspect that it might.


Conclusion:

Coating both sides with acrylic spray protects the ink from water very well. A single light coating is sufficient. It might be sufficient to just coat the side with the ink. Some inks resist water, and coating paper with acrylic spray may be unnecessary. Spraying the paper with enough acrylic to soak it is not a good idea.

It's on the way! Check out this thread:
