I'm using 0.91.2 and not interested in multisig features. V 0.91.2 working great on my Win8 desktop for mostly watch-only wallets and on my XP stand-alone (no network access) for cold storage. Why should upgrade to 0.92.1?

Honestly, you don't really have a reason to.  There are no known security or issues with 0.91.2, and the biggest improvements outside of multisig were the OSX stability improvements.    The only other thing that changed was that we upgraded File-->Export Transaction History.  It did some erroneous things in 0.91.2, and now includes some extra data.

Well, there are also the armoryd improvements. I think enough code was moved around that you can't just drop armoryd into a 0.91.2 installation and expect it to work. That said, most people have no need to use armoryd, so the OP probably has no pressing reason to upgrade.

Something completely different:

Do you have any plans to support Trezor devices?

I've received two of them and it seems to be a very secure - if not the most secure way - to do bitcoin transactions. But the myTrezor web wallet still lacks a lot of functionality in comparison to armory.

Yes. Work got sidelined for various reasons but it's still in the cards. I believe Alan explained the current status in a post sometime last week.

We can't use USB drives any more.

How's that audio cable method coming along?

Why not just use a CD-RW? Unlike USB, a CD *only* transmits data. As long as the offline system doesn't execute random code it happens to find (*cough* AutoRun), and you verify that the transaction you're signing is the one you mean to, it should be totally secure.

That works as a fallback until something better comes along.

USB method was nice for being much faster than it takes to burn a CDRW twice

Coincidentally, we had an internal conversation a couple months ago about trying to find USB devices that had "burned in" firmware.  My understanding was that the "dynamic" firmware on many USBs is a convenience to the manufacturers, but it is possible to get devices (and should be cheaper) to get one with firmware that can't be swapped.  I guess now is a good time to discuss those options and see if we can find a manufacturer that can guarantee that to be the case.

Of course there are other transfer methods that would be better (theoretically), but the USB capability is a boon for security-vs-convenience for most users.

Someone did post recently to the audio-cable comms thread with a decent xfer solution.  There was still some uncertainty about using it in less-controlled environments (i.e. making sure that both devices can "hear" each other).  But it was promising nonetheless.  If we can make it work, we'll make plugin that people can use for it.

I thought using the policy editor to totally disable autorun/autostart on ALL devices on ALL my computers solved these issues but I guess that won't stop this firmware threat.

Good to hear about the "burned-in" firmware. Hopefully this will drive making firmware read-only - may need to name it something else. In the mean time the article does mention that we can protect against BadUSB attacks by limiting the devices that get attached to our computers to those that have remained in the physical possession of a trusted party at all times.

Hi,

I would like to know if Armory will implement something like:

1- I create a lockbox (2of2) (Bob and Maria)
2- Bob and Maria will simultfunding the lockbox
3- I want to see an option (If Bob and Maria agree) to be able to return the bitcoins sent to lockbox.
4- If Bob or Maria doesn´t agree to return the bitcoins, the bitcoins sent to lockbox will be locked until one of them agree.
5- I would like to see an option (when creating the 2of 2 lockbox) to specify a date to automatically return the bitcoins, if no action occur.

Possible?

Success, so far!

We got 3 BTC in donation matching so far in the first 24 hours!  (6 BTC total donated to EFF, CNC and CDC).  We have updated the listing on the donation match list:

https://bitcoinarmory.com/donation-match-list/

If you've upgraded to 0.92+ and you support the cause, please help out!  You can use any existing Armory wallets and balances, without any trouble or having to create/fund any new wallets or lockboxes.  The process just creates a regular transaction where only half the coins being spent belong to you.  The act of signing the transaction commits you if and only if we also sign it, which commits our funds as well.

You simply import one of the notes, add a note from one of your wallets of equal value, then sign it and send it to us.  The coins never leave your wallet if we never sign it (which commits our funds, too).    We posted some pretty thorough documentation here, and we'd appreciate the feedback on it.  




@teste

1-4 are already part of the process.  The coins enter the lockbox, and stay there until they agree on what to do with them.  If they want to simply return the money back to themselves, they create a transaction doing so and both sign it.  If one party will get all the funds or some proportion of the funds, then they create such a transaction and both sign it.  There's no restrictions on what you can do with it once it's in the Lockbox.  And if not all coins are moved, the rest will remain in the Lockbox and still require multiple signatures.

#5 is not possible in an automated fashion (at least not without trust).  If the coins can't move until they both agree, any "automated" coin return process will give one party an edge to scam the other.  For instance, if it's buyer-seller escrow and the coins are supposed to go to the seller after 30 days, then the seller doesn't have to send the merchandise -- they just stop responding for 30 days and they get the money.

If you want #5, you must include a third-party who can arbitrate.  If the coins need to be moved and one party is uncooperative, the third-party can verify the terms of the agreement and help get the coins to where they're supposed to go.

@etotheipi

1- What I would like is a collateral incentive:
(The collateral serves also as incentive to follow the protocol (e.g. that Bob is not lazy or careless and forget to release the payout tx).

2- Question: The bitcoin protocol doesn´t allow to specify a date to automatically return the bitcoins to people that funded the lockbox? (I would like this feature, because a lockbox participant may for example, die.) But I would like to know if is possible too, have an option to (any lockbox participant) extend the term (to return the bitcoins) that "was"specified when creating the lockbox.

Sorry for the bad english.

I suspect you grabbed the latest versino of 12.04 which is 12.04.4.  The website clarifies that the bundles were created before that and should be used with 12.04.3.  It has a download link to get 12.04.3.  I've been meaning to swap out the bundle packages so it will work with .4 but we just forgot to do it for 0.92

The Armory download page has a link to 12.04.3.  When you click on one of the offline bundles in the download table, read the text that shows up and you'll see the link.  Create a new VM based on that.

Hello. I just wanted to send a friendly reminder to everybody. We've started getting bug reports for OS X 10.10. I do appreciate everybody taking the time to give Armory a spin on 10.10. Smiley I also wish to remind everybody that 10.10 is a work-in-progress, with a final release 2-3 months from now. A lot of things are going to change between now and then, with the OS becoming more stable. Remember, what you have right now is a preview; it's going to be a bit wonky.

If anybody wishes to post a bug report, I appreciate it. I'm also planning, for now, to close most of them unless there's very specific info. (Example: "When using 10.10, whenever I click the "Send Bitcoins" button, Armory crashes. Here are my logs and the bug report that OS X offers to send to Apple. I'm running Armory 0.92.1.") I'm aware of general things like Armory hanging randomly. That's obviously not good. I just want to wait a little while and see if the problem fixes itself, which I believe it will. Don't worry, I'll give Armory a spin every time a new dev build comes out. Wink

Thanks!

the pain w/ this upgrade just won't stop.  just now am almost done downloading bc to 12.04.4.  as you know, have been having trouble with the torrent so had to resort to p2p.  now i'll have to install 12.04.3 on both systems along with the bc.

i think i'll just wait for everything to be 12.04.4 compatible

I'm having difficulty signing a transaction on my Raspberry Pi, recently upgraded to 0.92.1 (using the package downloaded from Secure Downloader).

I'm using the extras/cli_sign_txdp.py script, as I always have. The error I'm getting is:

Code:
Traceback (most recent call last):
  File "extras/cli_sign_txdp.py", line 28, in <module>
    wlt  = PyBtcWallet().readWalletFile(wltFile)
