This should be pocket size device with\nsomething like 256kB flash and 80 MHz CPU, talking with the computer over\nUSB. User will prepare transaction on the machine, send it to the device,\ndevice shows target address on the display and user confirms it by pressing\nthe button.\n\nWe're trying to make bitcoin payments safe even on hacked computer. For\nthis reason we're also implementing SPV so device don't need to trust\ncomputer with any kind of information. The biggest existing problem is that\nuser cannot be sure that the address displayed on computer screen is\ncorrect and he's confirming valid address.\n\nI don't have any solution for this problem yet. I just appreciate an\nactivity in payment protocol area, because it can (with some care) solve\nthis problem and my appeal si to keep all this simple. I'd be very happy\nwith simple payment protocol which can be implemented even on devices like\nI'm working on, so device with few widely used certificates stored in the\nmemory will be able to display origin of the invoice and confirm its\nvalidity.\n\nslush\n\n\nOn Thu, Nov 29, 2012 at 1:30 AM, Watson Ladd \u003cwbl at uchicago.edu\u003e wrote:\n\n\u003e After doing more thinking, what about letting a spend sign more\n\u003e information associated with the transaction, such as a transaction ID\n\u003e provided by the merchant?
