Is there anywhere I can see an example of a Wallet being restored from the paper backup?

Here is demo that I did for a user:

http://www.youtube.com/watch?v=WTwbc3fJsEg

At minute 29 we get into restoring from a backup.

There is quite a bit of content on this video although it's just an unedited google hangout so the quality is not so great.

I am concerned about usb key security (I am ultra paranoid).

Currently the safest method for transferring unsigned&signed transactions is to type it by hand into the computers, right? Now I am asking myself if I can loose my Bitcoins when I have a typo in my transaction plaintext (which is very likely) or does Armory check the file integrity and I just need to check the transaction details Armory brings up to me.

Or should I better wait for your audio transfer feature? (So awesome!)

The audio transfer feature is 1 or 2 releases away, so you might have to wait a little while.

A USB key is reasonably safe if you only use it for only this purpose on only one online computer.

If you go with manual entry that is the safest although most inconvenient. You do not have to worry about losing your bitcoins. You will have a chance to verify and double check the receiving addresses and amounts before you broadcast your transaction. If you took the time to type it all out, you can take the time to double check the receiving addresses and amounts.

Hi,

Im using Armory 0.9 Beta on OSX, it seems to sync up with the network and stuff OK, but in the bottom right where it either says "disconnected" or "Connected (288888 blocks)" it flashes very quickly between these two messages, like a couple of times per second.

Sometimes it is predominantly 'disconnected' but I can see it flashing, and sometimes it is 'Connected (288888 blocks)' and it flashes...

Anyone else experience this/able to help me troubleshoot this?

Thanks.

This sounds like your bitcoin Qt has reached -maxconnections and won't allow Armory to become max+1. Maybe try launching Armory the instant that Bitcoin client is launched, as it could be that your router is limiting p2p network connections (this will give Armory the best opportunity to be allocated with one of the p2p connection slots)

Even if that's not it, it would be useful to have some mechanism whereby Armory can take priority over other connections, as I've had this problem myself (solved by changing the network environment to allow more p2p connections to bitcoind). Possibly a point for core development, though.

Carlton i think you might have hit the nail on the head here... I have modified my bitcoin.conf to only allow Bitcoin-QT to have 10 connections max, also I am usually letting it sync fully (maxxing out the connections to 10) before starting Armory, so I guess it sounds like what you have experienced...

i do also have a slightly dodgey router though, even though it is supposed to be decent it needs a hard reset once or twice a day which I KNOW is not right but I have tried absolutely everythign to sort that out...

Will try opening Armory quickly after Bitcoin-QT is opened to try and get it in a 'reserved' slot when I get home tonight

Just to follow this issue up, this worked perfectly for me. The next thing I can think of is to add Armory as a forced connection into the bitcoin.conf file so that I don't have to worry about when I start it up...

If I was going to do this, how would I go about it? What address does Armory connect to QT from? I take it it will look something like:

Quote
addnode=127.0.0.1

...but bit of n00b about this stuff. Thanks

If you don't have the private key for "your" bitcoins then you have no bitcoins.

FYI, I'm not positive about this because I'm not that familiar with Tor, but I believe when using Tor, all connections appear to be from 127.0.0.1... so it's not necessarily safe in all  environments.  Someone please correct me if I'm wrong...

Is it possible to issue command line arguments when using Armory?  Such as "bitcoind listunspent"?

Thank You very much.  I will also try it myself as Armory has just finished installing Smiley

@Alan:

Since you already have the possibility to generate QR codes for paper backup of wallets, would it be possible to implement a feature to print/print to screen a QR code with the offline wallet transaction's data so it could be imported elsewhere easily (and be less prone to input errors)?

Yes, but you have to use armoryd (Amory Daemon) rather than the Armory application.

To run the Armory Daemon:

Build Armory from source code following instructions here: https://bitcoinarmory.com/download/building-armory-from-source/

You also need txjsonrpc from here: https://github.com/oubiwann/txjsonrpc

You can just clone it and put the directory right into BitcoinArmory

To play with it open a command line interface and enter:

python armoryd --testnet <path to testnet wallet>

Open another command line interface and send commands to it like this:

python armoryd.py --testnet listunspent

etotheipi and team, thanks for creating such an awesome and secure client!

My installation might actually be a bit below memory specifications, and may run slower than others', but it does work. The online machine has 4GB RAM, running 32-bit Linux (Fedora 20, upgraded using fedup from 17 -> 18 -> 19 -> 20). My two redundant offline machines, which are identical, are 455MHz Pentium III boxes with 256MB RAM, running Ubuntu 10.04 LTS and the Armory offline bundle.  (I tried to install Ubuntu 12.04.3 on the offline boxes, without success. I installed Ubuntu from CD, and one of the machines apparently has a defective CD-ROM drive, resulting in a 40-hour install that ultimately succeeded -- luckily, there were no blackouts during those 40 hours, and the cats didn't unplug the machine ... 8^)

When I instantiated the second offline machine, I used only the paper wallet backup from the first offline machine to recover my wallet, and (of course) it worked like a champ. That was my own exercise in making sure this stuff really does work -- and it does!

Thanks for the positive feedback!   Understandably, most people post and communicate with us when things don't work, and it's not a high priority to contact us when it does work.  It makes me feel like it doesn't work for anyone, even though it obviously does -- we had more than 20k downloads last month...and less than 20,000 nasty emails Smiley    So, it feels good to hear a success story occasionally.



Just an update on the new version:  I decided there was a new feature I wanted integrated that was too good to wait for the next version.  So I pushed this next round of testing back a couple weeks while we iron this out, which also gives us more time for some internal testing.  Hope to have it finished by mid next week!

You're welcome, and please consider this an implicit plea not to discontinue the offline bundle for Ubuntu 10.04.

The 0.91-dev branch on GitHub works for me well enough that I use it as my primary wallet.

Although I wouldn't normally recommend this, I think it's no so bad to do that as long as it's your online computer with watching-only wallets.  Anything stupid that the online computer does will be caught by the offline computer (as long as you actually check all the transaction details before continuing).

Of course, I may be neglecting some corner case situation, so I still wouldn't put an official endorsement behind it.  But having a stable version that does the reviewing and signing certainly reduces the risk considerably.  (but definitely don't use it for your offline computer yet, unless it's tiny amounts of money)

Yeah, I think I still use 0.88 on the offline computer because the risk/reward of updating the offline machine isn't favorable.

I thought maybe I should add a "don't try this at home" disclaimer to my other post, but on the other hand I think anyone capable of using git can make their own risk analysis.

Cannot get Armory to sync, any tips? It Freezes at 99% and has set there for days

I've tried every solution I can find so far:

-Rescan Database
-Rebuild and Rescan Database
-Ensured my PC time was synced with time.windows.com

So far nothing ive been doing has worked, the database refuses to finish.

Any ideas? I'm locked out of my wallet!

By the way, I am not posting the next testing version for a couple days, but it would be stellar if someone with a fresh Raspberry Pi could test the Raspbian build I posted a couple weeks ago.  I don't need a full report on functionality, etc... just want to know if I got the dependencies right and if it runs at all on a fresh Raspbian install.  I'm not very confident that it will, but I'm ready to be surprised!

I apologize if this is answered elsewhere but my Google powers failed me today apparently. I'm curious how, in a watch-only scenario where there is an offline client running used to sign transactions, the watch-only version of Armory generates new addresses when you select "receive bitcoin" for a new address? Aren't the public keys derived from the private keys? How are the public keys able to be generated if (as I understand it) all of the signing / encryption happens on the offline machine?
