[ESHOP launched] Trezor: Bitcoin hardware wallet

[grau]

The coindesk post might sound a little misleading but that happens in communication.
I hope they will at least correct the link to myTREZOR

The CoinDesk article was compiled without interaction with me, interpreting quite freely a press release and our web sites.

The back end serving the transaction history for myTREZOR was developed by Bits of Proof. It was delivered in source code to SatoshiLabs and is operated by SatoshiLabs.

The Bits of Proof software stack is a generic purpose foundation for enterprise use of Bitcoin as demonstrated also by this project.

It is the shared goal of CoinTerra and Bits of Proof to establish BOP as an industry standard. Details of this plan will be out in few days and will be surely positive for TREZOR.

1. You connect the device into the USB and run Bitcoin wallet software
2. It automatically recognizes the device (by matching VendorID and ProductID of USB bus)
3. Software ask for master public key. Then it will be able to show your addresses and their balances.
4. When you want to send some coins, software creates template of bitcoin transaction and send it to wallet device.
5. Device displays transaction summary on its display and ask you to confirm transaction by pressing hardware button
6. Device signs transactions using private key stored in the device and sends signed transaction to desktop software.
7. Desktop software sends signed transaction to the bitcoin network.

Will it be safer to connect it OS where viruses and key loggers are likely to be found(except Linux-based) ? I think it will better to send using Wifi though a new wallet should be made/modify according to Trezor. Home-network will be most secure. It should be encrypted with WPA not WEP as WEP bypassing softwares have been introduced. BTW great project.

Kindly,

Nice analogy by our Spanish friends at ElBitcoin (http://elbitcoin.org/llega-trezor-el-colt-45-del-mundo-bitcoin/)

"With the Colt 45 revolver, self-defense is no longer the privilege of a few, but a right that anyone could assert." Now you can defend yourself in the Bitcoin world as well, hence TREZOR is "the Colt 45 of the Bitcoin World".

Nice analogy? A Colt 45 may give you a false sense of security, but in real life it rarely helps; on the contrary, it is a great tool for criminals...

I like the analogy about something being a privilege of a few that later became something that everyone can assert. Not the fact it's being compared to a gun.

Are you serious? Firearms are the great force equalizer. Give an 80 year old woman a knife against an attacker and what do get? A dead woman. Give her a handgun and she's got a fighting chance. This comment has convinced me that you're either a troll our have such a skewed prescription reality that your "insights" are worthless.

Sorry for having brought that off-topic discussion into this thread.  Let me only say that real life is not like the movies.

awesome device!!!! Just tested my trezor

Just a question, is it already possible to sign messages with addresses?

Yes. But there is no UI in myTREZOR for that feature yet. If you are adventurous you can experiment with cmdtr.py utility here: https://github.com/trezor/python-trezor

I have had JorgeStolfi on ignore for the last four months. I encourage others to do the same.

I thing you hash the normal seed with the passphrase or something like that.

Encryption passphrase is additional protection of the seed. You can imagine that it is yet another word of your recovery seed.

If you use passphrase, every time you want to access your funds, you need Recovery seed AND your passphrase.

Do you know if using a particulary short passphrase like bob will reduce entropy of the seed.

No, it does not reduce entropy. But it does not add significant protection either. Anyway, it is better to use even weak passphrase than no passphrase, for case that somebody get access to your recovery seed (evil maid attack).

Thank you for this clarification. Good luck with your new affiliations.

Got my Classic today, thanks guys! Happy to have crowdfounded this project

Hi guys,

I recieved my trezor today and started playing around with it. I can only say : THANK YOU for this great device and great service!

I noticed some things regarding "myTrezor" :

1. There is no indication of the change addresses that are used apart from being show during the "sent dialog". Is it possible to see them somewhere in the UI?
2. If I sent some coins to myself (sent and recieve addresses from the same trezor wallet), the address I sent to is "purged" from the used addresses dialog. Why?

Keep on rockin!

Best,
 chris

There is no official feature and it would require using a external program which could put you under potential risk.

I was very happy to see the mailman today ;-)



my friends will be happy, too.

How would it put you at risk? The whole idea of the Trezor is that you can use it with any untrusted device safely.

Right :-)

Got my Trezor today.  Love it.  So simple to set up, and use.

Can't get Linux Chrome to load the plugin. I'll investigate that later.  Works fine in Firefox.

Thank you.
