Title: Defunct handhelds devices could be hacking for Bitcoin usage?
Post by: Bitbird on July 05, 2012, 11:12:38 AM
Could defunct handhelds devices be hacking for Bitcoin usage? There're service like Coinapult (https://bitcointalk.org/index.php?PHPSESSID=4c664c501b764cfbe54d8d8035d67ca5&topic=76493.0) which providing Bitcoin via email and SMS. Perhaps some kind of integration can be achieved. Or simply host a bitcoin client as a dedicated mobile node should be working. What do you think?

Peek has discontinued its low-cost, email-and-texting service but is challenging hackers to "build something great" with the leftover handhelds, according to The Verge. The Peek devices include a 2.5-inch screen, a QWERTY keyboard, an ARM7-based processor, and a GSM cellular modem, according to the company.

Should be possible!
Are you aiming for a full client with blockchain, or a lite client which connects to a central server?

Either way, the big obstacle for any of those approaches is how to get online. Reading "gsm included" means hassle and costs for a sim card. Have something with wifi instead? Then you will not have internet everywhere. Or only internet when doing a transaction, aka mesh net or the POS as a relay? You better be sure the data you receive is not forged!

But besides all that.. The hardware should be strong enough! :-P

I think it should be depended on how a device connected to internet? A full client with blockchain would be more safe but also consuming more power and bandwidth. A lite client could be more energy efficiency and need not always connecting to the net, but will provide more security.

For a mobile solutions GSM seems better then Wi-Fi, at least outside some big cities. Therefor sim card/GSM might be the only choice. Furthermore, it's possible to use open-source GSM platform like OpenBTS (https://en.wikipedia.org/wiki/OpenBTS) as it's access point.  ;)

Must say I'm not an expert in GSM, any suggestion/commentary would be great.

You can use Strongcoin with an amazon kindle (perhaps other e-wallets too).

You get the benefit of a lightweight client and it's unlikely anyone has hacked your kindle with keyloggers etc.
