    The fist episode is in an airport and depicts a girl and a boy casually arguing about bitcoin, hackers, security etc.
     



    The second episode is in a restaurant and again depicts a boy and a girl and while they casually discuss bitcoin the girl gets some cash from some anonymous person and the boy wonders what's going on ...
      


    Episode three will come later on Smiley

    Posted a tutorial video on YouTube on how to install the GreenAddress wallet as a Chrome app from GitHub.

    https://www.youtube.com/watch?v=zF3Xar5hJ_0

    Installing from GitHub as per the video is useful for the following purposes:
    • Avoiding the google login on the google chrome store
    • Make sure you are running the open souce version
    • Avoid autoupdates
    • Play with the source code


    - updated description
    - updated coming soon
    - added links to iOS app both store and hockeyapp
    - added links to blog, api, translation page

    - added links to cartoon ads
    - added video tutorial[/list]

    We don't have the app for iOS yet but we could probably do it quickly given we use Cordova.

    Keep in mind that Apple will probably reject it from the store but I guess jail broken phones could use it.

    On top open sourcing the Chrome App today we open sourced the Android App (based on Cordova). The Play store has been updated but the new version will take up to a few hours to be available. If you are interested in a bounty for a WinPhone or iOS port get in touch (we'll soon announce them) https://github.com/greenaddress/WalletCordova

    Hello,

    We added a blog, a non stable API in development and a design/implementation document regarding the GreenAddress wallet service .

    All can be found on this first blog post:  http://blog.greenaddress.it/2014/04/05/firstpost-updates/

    Direct link to the pdf document : http://ghgreenaddress.files.wordpress.com/2014/04/greenaddressp2sh2of2hd-3.pdf

    Thanks

    Why does the name of this service remind me of a proposal Mike Hearn floated last year in the Bitcoin Foundation forums?

    No it was worst it was a proposal by mt gox to make their address special to miners. https://en.bitcoin.it/wiki/Green_address

    The idea was mostly independent in early 2013 but it is quite similar to an idea that Gavin had (see https://gist.github.com/gavinandresen/5616606)
    The term greenaddress as far as I know was coined by Jan Vornberger (of Bitcoinwalker and Hive fame) and in the original incarnation didn't really work but we hope to provide a better solution for it to work (out of band and from a P2SH 2of2, more details in the pdf).

    Your site looks absolutely awesome. Best of luck. I have one doubt though. In the "Send Money" page, there's an option like this:
    Quote
    Fee (0.10 mBTC / kB) will be paid by:   Me   Recipient
    I assume the recipient paying the fee means it will be deducted from the amount to be sent?

    poordeveloper:

    Correct, that's nothing more than picking whether the fee will come out of the amount you are sending or from the reminder in your wallet.
    It's probably not a particularly useful feature and I'm not sure whether it should stay as it may confuse some users.

    What do you think?

    What do you think?
    At first, I must say I was a bit confused - at first I thought maybe it was a new protocol feature I hadn't heard about until now (I've been out of the Bitcoin world for a month of so... and things change fast). It took me a while to actually see that no such feature exists in the protocol, and so this should mean whether the fee is included or not in the amount to be sent (but still I wasn't sure - I could even think you implemented this system for payments to GreenAddress users, since normal Bitcoin TXs don't have this option).

    With this option, I'd add the data in a table, like the Cryptsy withdrawal forms do.

    I'd clarify this in the options themselves (Me/Recipient), with a tooltip maybe.
