How many units sold total? Only a rough number!

roughly few thousands

I would think that most of your potential clients (the people who would consider buying a Trezor) own 10 bitcoins or more. Let N be the the number of such persons in the world.

Check the distribution of bitcoins by addresses as of block #320000 (2014-09-10 13:55:18)

There are only ~115'000 addresses with 10 BTC or more in them. Methinks that this number is an upper bound for N. (While there may be people who own more than 10 BTC, but keep them split among several addresses, there must be also people who own several addresses with 10 BTC or more in each. So these two errors should cancel to some extent.)

So, if you sold several thousand units already, you may have already attracted several % of the potential clients. That is quite good for a product barely out of the factory.

It is also likely that several tens of thousands of those N clients cannot read English and the other languages that Trezor supports, and therefore are temporarily out of the market.

Would using the same Trezor with Electrum and Electrum-LTC work?

Yes. It would

I have a question. How should I go about using my Trezor to also store my Litecoin stash? So a single seed originaly created by the device to also be used for creating LTC keys.

Would using the same Trezor with Electrum and Electrum-LTC work?

Any thoughts on that?

Hi everybody ! any new about the Peercoin implementation on TREZOR ? I have not seen any new information about it. Would be nice to know if it has been done, currently on development, or if nothing is currently planned.

Thanks.

Can someone please provide a short step-by-step tutorial on how to use the Trezor to sign a hash of a document?
Thanks

From memory:

Click on the account that you want to use. Then near the top right you will see a sign and verify button. Click it. It will bring up 2 forms that you can fill out, sign and verify. The first field will be the message. Enter the message that you want to sign in the message field. The second field will be the address. begin typing the address that you want to use. it will detect the address you are entering and provide an option to fill out the rest of the address for you. Click sign. Now look at your trezor. It will ask you to confirm that you want to sign the message. Confirm that you do. Now enter your pin. Look back at the form page in your browser. you will see that the formerly empty signature box will now contain a series of characters. That is your digital signature.

Thanks. So this appears to be signing of messages disconnected to transactions. And it is signing with my private key.
Is there a way to include a message in a signed bitcoin transaction? In other words, can I include a SHA256 hash of a document and include it in a transaction that gets recorded on the blockchain? I think this can be done with some clients (although I do not know which ones can do it). But can it be accomplished from my Trezor?
Thanks

Molecular has designed a way to hash your document and create a private key out of it. You can send a very small amount of BTC to that address to "timestamp" it and proove you own that doc at a certain moment of time. Don't know if you are looking for that?

If you want the proove to be public, I think you can do the same by creating a public address out of the hash of the doc. But I never that that
(I used the method of Molecular to create a certificate of my Silver Casascius coin Wink

)

http://www.proofofexistence.com/ might be what you're looking for. At least it's very similar (identical in function, I think) to what dnaleor is describing and what I had implemented for proving cascascius coin existance. btw, no invention there: I just used the sha256 of the document as a private key (there's no conversion, both are just a 256 bit numbers), derived the matching bitcoin address and sent money to it. Adavantage: you can still move that money. Disadvantage: you can't read any 'message', just verify it has existed if you have it.

"Is there a way to include a message in a signed bitcoin transaction?" <- I'm not sure what to make of this. You can sign a transaction, you can sign a message. You can encode a message into a transaction.

I had hoped many more would have been sold by now given 141,614 subscribers to /r/Bitcoin and 393,788 accounts in bitcointalk. Plus the hundreds of millions spent on ASIC preorders.

Currently there's no support for the Trezor in the wallets that people are used to using, thought that'll change eventually.

I wasn't in a huge rush to order a Trezor for myself because I'm reasonably able to secure my coins, and didn't feel that they were at risk. The main reason that I picked one up was more so that I could evaluate it and decide whether to start giving them as gifts to friends and family that use Bitcoin.

Speaking of, any plans for a Black Friday discount?

Again, is trezor supported by multibit hd or is this still in development and I have to use only trezor wallet?? I can't find anything online, except is stated on multibit website that this is possible, but I don't want to go and download HD because I have already regular multibit on my computer.

Thanks

Trezor + MultiBit HD is still in development but I've seen screenshots of the work in progress and it looks promising.

Thanks

Sadly most of the people would rather invest in shady mining companies instead of increasing the security of their coins.

I'm sure this won't soothe you, but you're the foremost name now, and if there ever is a healthy market for these types of devices, you'll have head start.

Meanwhile, people continue to "invest" in alts and cloud mining...

Even I cannot trust my own computer, because I haven't seen and read sources to all components it is running (BIOS, kernel, hardware drivers, OS, etc.)

I wasn't your marginal consumer. I probably would have paid 5 times what you were asking if that has been the price. So it sort of confounds me that there isn't more interest than is.

Have you guys put much thought into increasing the value proposition by working with websites and services to help them to integrate your technology for authentication. How cool would it be if for each website that you logged in to, you could simply click login on the browser, plug in your trezor, get a prompt on your trezor, and then just hit confirm on the trezor. It would be infinitely more secure than the standard current credentialing method of typing in a user name and password and even easier.

I received today my Trezor but it doesn't work. Sad

I connected the Trezor to the computer, a padlock is shown in Trezor's screen. I installed the plugin and allowed firefox and chrome to run it. But all the time I see the same: "Connect your TREZOR device to the computer."

I tried with differents computers, Windows 7, Windows XP. 4 Differents USB cables. Restarted. And nothing.

This is my log:

["error","Mon, 10 Nov 2014 13:32:41 GMT","[app] Loading http transport failed",{"cors":"rejected"}]
["log","Mon, 10 Nov 2014 13:32:41 GMT","[trezor] Loaded plugin 1.0.5"]

try with a different USB cable. sometimes thats the issue and causes the trezor connection to cut in and out

I tried 4 different USB cables Wink
