[ESHOP launched] Trezor: Bitcoin hardware wallet

[AussieHash]

So, basically,  robbers will not want your password in order to check how much is the balance on your Trezor.  They will demand some satisfactory amount of money (or bitcoins, if they believe you have them), and expect you to do whatever you need to deliver it.

Wrong. Armed robbers might know your net worth, but they can never know how many bitcoin you have.

Unless you told bragged to someone. Or posted it on a forum. Or answered a "how many bitcoin do you have?" post on reddit. Or are on this list https://bitcointalk.org/index.php?topic=321265.0

Looks like ethereum dev team are in the world top 20!

They may know that you just sold your beach home and got paid in bitcoin.  They may have installed a spy program in you laptop and silently watched as you checked your balance and updated your cold wallet.  They will evaluate your car and house, and guess how much savings you may have.  Anyway, if their their idea of the size of your hoard is too low, lucky of you, but if it is too high, it is you who will be in real trouble.

Chances are, if you are facing an armed robbery, the perpetrators have probably done their homework and have been casing you for awhile.   That would be really bad luck if you were randomly selected to be robbed.

If you drive around in one of these https://i.imgur.com/P9EFqWX.jpg your armed robbers will have a fair idea that you have a large bitcoin holding. If you're not stupid you can just tell them you hold your net worth in fiat in a bank.

Edit : the buyer of this car is on the top 500 list for example, apparently he drives it to bitcoin conferences

Edit 2 : email to Trezor support many months ago
Q) Years ago there were stories of iPod owners being mugged and targeted because they had white earphones on, won't people with trezors or trezor stickers become targets as they are carrying around potentially 1,000+ BTC with them ?

A) Carrying TREZOR with 1000 BTC to internet cafes isn't probably a good idea because of the rubber-hose cryptoanalysis method (http://en.wikipedia.org/wiki/Rubber-hose_cryptanalysis) which is still possible

[Nexigen]

Seriously this is really awesome. If I ever get enough bitcoin to justify a Trezor purchase I will definitely do so.
Man it can even be put into a glass of coca cola and nothing is happening. Safe as hell 

Keep it up guys, can't wait for more progress!

Anybody with BTC1000 can afford BTC0.2 for an extra trezor for pocket money.

my understanding is that you do not enter the seed as a string of words, but rather follow prompts from the mytrezor page such as:

Exactly. Old firmware (1.2.0 and older) used 50% fake words. New firmware (1.2.1+) always asks for 24 words (making it 12 fake words for 12-word mnemonic, 6 fake words for 18-word mnemonic and no fake words for 24-word mnemonic). And we also switched the default from 12 words to 24 words, so most of the people will not see the "fake words" feature anymore.

Without any fake word for 24-word mnemonic, the entropy is reduced from 256bits to only 79bits. This is not acceptable for long term storage

This is only in the scenario of seed recovery for a lost/stolen/broken Trezor.  Either don't lose your Trezor, or move your coins after the recovery process.

This is only in the scenario with seed recovery for a lost/stolen/broken Trezor.  Either don't lose your Trezor, or move your coins after the recovery process.

Unfortunately, this is also the scenario of people trying to be smart and generate their own entropy with dice. The problem is that they have no good way to import it in the device. Not recovering the device is something you can do if you trust the random number generators, which in general is not a good idea. But for now, I trust the mix of pc and hw rng much more then the recovery pc...

I would love there to be a way to setup and seed recover a Trezor with an offline air gaped computer. I doubt this can be done from the python command line scripts or else it would be in the manual. Even when electrum/etc support becomes available, it will not be to setup or recover a Trezor (at least initially)

Hardware wallet wow thats cool didnt know you could have one of those.

[keithers]

Hoping that my Trezor arrives today...I am anxious to try it out .   Will definitely report back here...  Shipping was much faster than I assumed it would be... I thought I would be waiting for at least a month...

There is not reason why not adding most secure option for entering recovery seed directly in your trezor using only the two buttons. Even if it takes one hour to enter all 24 words using the two buttons, I would preffer to do it in this secure way.

I mean as another option, together with the current quick way to restore

Maybe later editions can come with a 10 digit keypad where you can enter passwords into it directly...

Looking into getting one of these but they are quite expensive when I could just use a cold wallet....but its so damn cool and sexy.

Problems arise when you are about to spend your so-called cold wallet.

Trezor,

I absolutely love mine... received it today! I've been playing around with it and moved my BTC from Armory to it.  So happy to have an easy transactable method of cold storage without having to wait for the blockchain to sync.  LOVE it!!  I am however looking forward to a downloadable wallet that will work with the Trezor.

Just got my Trezor.  Transferred some from Armory cold storage.  
Just wondering how much BTC would you be comfortable putting in it?

[seandaniel]

do they ship in asia?

I feel comfortable putting all my BTC on it.  100+ ...  wallet32 from android you can reproduce your wallet if you need.  That's just me though.  I believe that many of the major wallet dev's will implement Trezor compatibility very soon.
