[ANN] Amazing new device

News Flash!

From the Brilliant science labs in Wisconsin comes the latest in Bitcoin technology!

Presenting the World Premiere of the...


Moolong Device!

As you can see it has the Bitcoin client showing on the screen. And of course the screen is touch-capable! It is designed to wear as a keychain or from a gold chain.*

Heh, a little thin on the details there.

Oh, you'll have to wait for that. I won't be giving away trade secrets. Though if you read everything very carefully you'll understand why.

A portable keychain-sized device able to run a Bitcoin client? Interesting.

But I will redescribe here another type of bitcoin wallet which I have talked about in the past, that would have a better form factor:

Bitcoins could be stored on a smartcard having a flexible e-paper display, flexible built-in keypad, and flexible LiPo battery [1]. Withdrawing coins from the card could require a user typing in an amount and a pin code, and then using a smartphone to scan a QR code shown on the e-paper display (or sliding the card in the merchant's payment terminal, which would scan the QR code). The QR code would represent a signed Bitcoin transaction to a pre-programmed address whose private key sits on some online server, which is only used as an intermediary step before forwarding the coins to the final merchant. The smartcard would effectively never connect to an online device during its entire life, making it un-hackable without having physical access to it. Smartcards could also be manufactured in pairs, or triplets, etc, to have clones of them in order to have redundant backups of the Bitcoins in case of a loss of one of the cards.

One might ask how the smartcard can sign transactions without access to the current blockchain. Well it is mathematically possible, because a transaction just consists of ECC-signing a few bytes representing the destination addresses.

[1] The technology for this already exists. I own one of those Paypal cards: http://gallery.drfaulken.com/d/8752-1/IMG_1466.JPG

What is the joke? The gold chain or the device?

What is the joke? The gold chain or the device?

it's just a $7.99 picture viewer keychain with screenshots. But it goes to show you that it's easy to hoax people about technology. OTOH, the $8 device probably would be good for storing QR codes of Bitcoin addresses.

I know of a 3.5" touch screen solution it includes the Beaglebone and the 3.5" touch screen that is coming out. Anyone could put it together them selves.

The beagle bone has a ethernet port so one could hook up to the internet and use the touch screen to execute commands(or write a GUI to do it for you)

since Beaglebone runs Linux one could hook up to a Wifi usb as it has two usb ports

For a non-technical user one would spend the money on the beagle bone ($89+shipping)
then the LCD 3" touch screen ($70+shipping)

and some Bitcoin client software for angstrom linux I don't think the Official client would compile with out some alternations and a Bitcoin lite client would be perfferable as the beaglebone doesn't come with much free space (1.5gb - 2.5gb)

I'll take 7!
