[ESHOP launched] Trezor: Bitcoin hardware wallet

[Anon136]

If someone finds your dollar bill laying around on the ground they can spend it. Dollar bills still work just fine. Dont give your trezor to anyone else, problem solved. If you lose it, oh well you only had 100 bucks on it or w/e is the analogue to what you might keep in your regular fiat holding wallet.

You see, here I disagree. Why would anyone buy a trezor for 120 bucks to only carry an average of 100 bucks around. Doesn't sound too practical tbh.

Well not for 120 bucks but the free market drives down the price of everything. Someday these things will be in a little basket on the desk of companies free because they have a logo on the back. In intermediate stages between here and there the price will fall dramatically. In a year I bet they will be driven down to 1/4 of the price.

you are correct. this is not the intended use I believe. if you lose it, your life savings are protected as good as you protect the seed.

To accomplish the use that anon136 proposes a simple phone app would suffice.

But he has a good point. What about this use case:

We have a trezor with RFID/any near field tech and can connect to our smartphone. Now we have a "hot"wallet on the phone for immediate expenses that can be funded by connecting the trezor and entering all needed security stuff. The amount on the trezor itself stays very well protected while the phone can be used at POS terminals and NFD/RFID terminals for small purchases.
For bigger purchases you could use your smartphone to directly send from your connected trezor to the vendor.

Should be possible right? Anything like that in the making?

this is looking more to 5+ years from now. when an RFID trezor would be almost as cheap to produce as a creditcard is today.

Your wallet probably costs $25-75 but carries less than $80 in it most of the time. think of the trezor the same way - you might only carry $40 worth of BTC on it at a time, but dozens of times you can refill it with $40 over its lifespan

Just discussed Trezor with a good friend of mine.

It would be awesome, if one day trezor could additional to BTC transactions also handle all cards needed in your wallet. Credit cards, driverslicense (ok, thats a far stretch ) , state issued ID , loyality store cards, giftcards ect. So instead of having to use multiple cards, RFID/NFD on the trezor is used for that.

Beware that the bigger the code, the more costly it is to validate, and the higher is the risk of an exploitable bug going undetected.

Does the processor inside the Trezor have some sort of memory protection, that would prevent some function from accessing data of an unrelated function?

Can the firmware modify itself?

[Anon136]

What about using your trezor to digitally sign arbitrary data? Does it have that functionality? I'm guessing it does since they have plans to use it for authentication but not sure.

That Coin Card is supposed to be out this Summer that you can load all of your credit and debit cards onto one card.  I pre-ordered one of those.   I am anxious to see how it works also.   Can't decide which one I am more anxious for...the Trezor, or the Coin card...

Coin is a great example of an idea making problems worse than they originally were 

Card payments are a complete mess today because high security systems (requiring a dynamic card authorization for each transaction) are coexisting with systems using static security (yay USA), so backends have to support all scenarios which leads to epic failure - such as card data read from a distance on a secure NFC card in country A, with great security and cloned on a magstripe card used in country B, with not so great security. Coin enables that scenario for all cards.

Bitcoin is built from the ground up with uncompromised security and Trezor is already out so ... stop being anxious

Coin is a scam. It'll never ship and even if it does, emv is coming soon and it doesn't support it.

I just received the TREZOR and wanted to setup everything.

System: Win 7 with browser Firefox and Google Chrome

Installed the windows msi bridge.
Opened the mytrezor.com
plugged in the trezor for the first time
It installed an update
now when I connect the trezor it only shows this and keeps "loading" without ever stopping:



I worte the support, but maybe someone had the same problem and found a solution?

PS: I plugged the trezor in the nearly same built PC of my brother and it worked there without hassle!

the trezor it only shows this and keeps "loading" without ever stopping:

Please try to disconnect Trezor, press Forget device and plug it in once again. Sometimes drivers get stuck on fresh installation.

Tried that multiple times already on 3 different browsers.

Even installed the msi again and used the "repair" function of the msi.

Really weird that it would work without a problem on the other computer but not on mine and my laptop.

In few days we'll release Trezor Bridge, a replacement for Trezor Plugin, which should fix these weird issues...

Ok, I will try it then again.

Thanks for the help anyway!

some usb ports have a lower power supply. had the same issue with some flash drives. try an usb hub with an extra power supply (active usb hub).
someting like this one http://www.ebay.de/itm/10-Port-USB-2-0-Hub-Aktiv-10-fach-USB-High-Speed-Verteiler-mit-Netzteil-/360802960503?pt=DE_Computing_USB_Kabel_Hubs_Adapter&hash=item5401884477

[TwinWinNerD]

Danke

I will go buy one now. Will report back in a few hours if that was the case

[Newar]

How much power does this beast need?

A friend has tested this solution/idea 5 min ago and that helped  .

There were some problems reported with the cables at one point but the fact you are using the same cable on both computers, one works and one does not, seems to rule out the cable - but you might try another one anyway.
