Hey people,
We (jalaman and molecular) have earlier this year started to scan the casascius coins we sell, insert a hash of the image into the blockchain (as proof of age of the coin) and include a printed certificate wrapping up the information about the coin and proof. Looks like this:
People find these useful and I think they have the potential to increase the value of the coin in the future.
So I figured why not offer this as a service so people can "roll their own" certificates. So after quite a bit of work, here is a page that helps you do this:
http://certificates.0x0000.de
The way it works is: you take photos or scans of your coin(s) and upload them. The site will combine 2 images (front and back of coin) into one and insert the hash into the blockchain (the tx id and stuff will be on the certificate), thereby making proof of age possible.
It will also produce a certificate you can download or have us print and send you.
It will also generate a text-file (list.txt) with all the relevant information to conduct the proof of age in the future.
You'll receive a file "bundle.zip" containing that text file, the certificates and of course (necessary to conduct the proof of age) the images of the coins. Looks like this:
Things might go wrong when you use the page. Don't worry, we'll fix it. Just record your session id (displayed on the main page) for reference.
Price is BTC 0.02 per certificate (including inserting the hash, of course).
For an additional BTC 0.01 we'll print the certificate and mail it to you
If you order any printed certificate we'll need your shipping address and also an email-address, otherwise the service can be used anonymously.
So, tell us what you think... we welcome any feedback.
