[ESHOP launched] Trezor: Bitcoin hardware wallet

[BurtW]

Sorry - lot of questions but need to figure out all the pros/cons and potential issues.

can anybody answer some/all these questions from experience - i.e. from actually doing it?

Thanks - usukan

I have tried entering the 24 word key into another BIP32 compliant wallet (I used Wallet32 for Android, but any compliant wallet will do) and recovered the entire wallet, all accounts, all transactions - that is how it is designed.

That is the beauty of BIP32:  with just the 24 words + the password you can recover everything.  With the same 24 words + your second password you can recovery everything under that password, and so on for as many different passwords as you want.  When I say everything I mean all accounts and all transactions generated from that 24 word + password combination.

FYI the PIN number is a Trezor specific thing and is not needed for recovery.

If you lose your Trezor you just buy another one and enter your same 24 words and you are back up and running OR just enter your 24 words into another compliant wallet.

I think a lot of your questions are answered back a few pages.  Start here:

Thx for implementing multiple coin support including Litecoin and Namecoin directly in standard firmware!

yeah would be great, how would this work, i guess it is not possible to put wallets of different coins on the same trezor?

OK thanks - will check back the pages

Cheers

https://mytrezor.com down ?

Makes me consider Electrum even more, just not sure about the privacy that way.

If you want privacy, use Trezor on Android with Mycelium through Tor.

Rassad, so Mycelium servers can see all our tx's and balances, right?

The xpub keys don't get sent to Mycelium server. The account gets set up just like a normal Mycelium account, where all the information on it is only on your phone. It just asks you to plug in your Trezor when the wallet app needs to sign a transaction. Mycelium servers do see you broadcasting a transaction (use Tor), and can tell which addresses are yours when you update balances (again, use Tor), but so can any node you connect to with any SPV wallet. At least Mycelium doesn't log any transactions or balance requests, and as far as anyone else on the network knows, your transactions originated from Mycelium servers, not from your phone.

thank you for this.  this is the first time i've seen on this thread where this has been made clear.

Check the emphasis. I don't think the link between your addresses are protected at all, they're just discovered in a different way (the same leakage any SPV mode entails)

Wooww it's so amazing! How does it work? I think trezor is the best wallet apps with the best transcaction. I decided to get my experience with trezor, it is cool right?

Trezor is a great wallet.  I especially like the fact you can reconstruct your entire account and transaction history from the 24 word seed.  This makes backups easy (not needed).

I gave my parent's a Trezor to keep their Bitcoins.  Safe, secure, easy.

i get that.  i was referring to the fact that the xpub is NOT transmitted to their server.  that's a good thing.

Is it safe to purchase a Trezor wallet from someone else (that you might not trust)? Is there any way that something could go wrong if the wallet was tampered with somehow?

How much value does a day devoid of paranoia hold to you?

The fact you through in "might not trust" tells me you know the right answer.

If you want to save a few bucks just wait for another sale or mine on slush's pool for a bit.

It's possible, although not an easy attack.

If you buy a possibly tampered trezor, you could just overwrite the firmware to make sure it's not been tampered with. But it is theoretically possible for the hardware to be changed such that it will accept the official firmware and STILL send the bitcoin to a different address than it displays to you.

But long story short, the few dollars you save buying a used trezor is very likely not worth it.

Could use this device on blockchain.nifo ? or just Bitcoin wallet-qt ?

[guitarplinker]

Neither of those support the Trezor. It has to be used with either Electrum, myTrezor, Multibit HD or Mycellium.

I missed where mining on Slush's pool gets a discount.
I was mining there for a month or so and thinking about going back.
I will check the FAQ again.

[unholycactus]

I've tried out Trezor and I love it.

I've had a few problems with my computer detecting Trezor but switching cables fixed it.

I'd also rather have it included with a micro to micro cable instead of a micro to usb.

For those wondering about shipping time, it only took a week to ship from Czech Republic to Canada.

I have a question about trezor... It seams that everytime I receive money it generates a new address....... Will I still be able to use the older addresses to receive bitcoin?

Yes , you can . no problem ( even it's not recomanded to reuse old adresses.)

[BurtW]

I would like to stress that the use of a different address for each transaction is by design.

Address reuse is strongly discouraged.

But, as stated above, if you really want to you can reuse them - again highly discouraged.

I want a payment address for my website though it has to be the same one every time
