Armory - Discussion Thread

[Roy Badami]

I have a feature request, that's kind of a thought-in-progress...
...

I'm not sure what UI change I'm really asking for here - maybe a preference that hides balances when the client is launched (and allows an individual wallet balance to still be viewed by means of a UI action)?
...
Thoughts, anyone?

You could drag the right edge of the Armory window to the left until the balance column is obscured.

Ah, so the long delay before Armory displays the balances is actually a feature, to give me time to do this....   That works

EDIT: Actually, that doesn't help if I actually do want to check the balance of the wallet I'm paying with - without revealing the balance of any other wallet(s)

There actually is a reason for the delay. Armory only shows balances after it has synced with the top block. Seeing that balance tells the user that it is now available for creating transactions. Armory really cannot allow users to create transactions unless it is fully synced. Not everything in Armory is as efficient as possible, but some things necessarily take time.

EDIT: Actually, that doesn't help if I actually do want to check the balance of the wallet I'm paying with - without revealing the balance of any other wallet(s)

So you would want to hide the balances per wallet. I think that's a great idea. Perhaps we can hide the balance of specified wallets and only show it in hover text.

Yes, I think so - although then I don't know what you would do with the totals.  As I said, it's still a bit of a thought-in-progress.

Is it possible to export a private key out of Armory, such that it can be used to sign transactions on some other platform or with outside code/script?

For now you could flag other loaded wallets as not yours then choose to only display the ones you marked as owned. Not very convenient but can get things done while we implement something better

Start Armory in Expert mode, go to your wallet's properties window, choose 'Backup This Wallet' from the right panel options then pick the 'Export Key List' option.

In the wallet properties view, there is a button named "Remove Imported Address".
It wants me to select which address to remove, tough im unsure which i imported.
As the wallet is deterministic, its possible to find out which addresses are imported. Is there a way to display said addresses?

I don't know if you tried but it will fail if the address wasn't really imported

Also they're clearly labeled https://i.imgur.com/E2sMkoP.jpg

Seems the wallet i was checking had no imported keys.
Another one has. Seems the feature i asked for already exists.

In the Wallet Properties, the first cell (#) will show Imported instead of the N'th seeded address

Simulfunding Now Implemented!

Updated the top post in the multisig thread:  we have been able to remove most of the limitations of the lockboxes, and now even have a clunky-but-usable simulfunding interface:

https://bitcointalk.org/index.php?topic=559776.0

The whole multisig section of the "devel" branch is extremely usable right now.  It now does P2SH for everything by default (but you can optionally use bare multisig), it handles signature merging, and now allows for multi-party simultaneous funding of lockboxes (and should be easy to expand for general-purpose, manual CoinJoin).

If you are already familiar with things like buyer-seller escrow, I'm hoping that the simulfunding stuff will be somewhat straighforward (despite there being lots of steps and moving things around) -- it's a complex process, but I think I've made it about as easy as possible for a totally decentralized app.  Besides cleaning up a bunch of things, I will work on documenting how to use the interface, and the things that can be done with it.

I think I will merge all the steps/options into a single "dashboard" which sorts everything by "organizer" and "participants".  It will show something like:

• Create Lockbox:
  
  • Organizer: Collect Keys
  • Participants:  Provide Pub Key
• Deposit (regular):  Send Funds
• Deposit (simulfund):
  
  • Organizer:  Merge Notes
  • Participants:  Create Promissory Note
  • Participants: Review and Sign
• Spend:   
  
  • Organizer: Create Proposed Spend
  • Participants: Review and Sign
  
  (Not sure what's up with the table formatting, but you should get the idea...)

Hi there!

After making some test with 100.000 addresses in Wallet, we have a problem signing the Tx's on offline server.
It takes several minutes to sign, I tried some tweaks on unlock method (just taking the addrObj which I need, and not all of the 100.000 addresses to unlock)
But later on self.wallet.signTxDistProposal(txdp) it stucks.

Before stuggling into modifying more code, wanted to ask if someone of armory see some
fast way to sign a TX in a hugh big wallet?

Best regards!

I'm fairly certain that this can be done without unlocking the entire wallet (which checks the validity of each key).  In fact, I was pretty sure we had done this already, but perhaps not.  Or maybe it wasn't sent to armoryd (isn't that what you're using?)

The problem might be that the wallet relocks itself after 10 sec and you are not getting to the signing before then.  So you have re-unlock it by the time you get to the signing procedure (and make sure you only unlock the specific keys you need, again.

[po0kie]

Yes -> armoryd

what do you mean with re-unlock it?
just setting: self.wallet.isLocked = False ?

[etotheipi]

You call self.wallet.unlock() to unlock hte wallet to make the keys available for signing.  If you don't do this immediately before signing, it could relock itself before you attempt to sign (it's like 5 or 10 sec timeout).

[po0kie]

yeah but the entire unlock just takes to long, it takes all the addresses from wallet -> not just the implicated tx addresses:

Code:

 for addrObj in (sorted(self.addrMap.values(), 
                             key=operator.attrgetter('chainIndex'))):
         Progress(naddress, addrCount)
         naddress = naddress +1
         
         needToSaveAddrAfterUnlock = addrObj.createPrivKeyNextUnlock
         if needToSaveAddrAfterUnlock and addrObjPrev is not None:
               ChainDepth = addrObj.chainIndex - addrObjPrev.chainIndex

               if ChainDepth > 0 and addrObjPrev.chainIndex > -1:
                  addrObj.createPrivKeyNextUnlock_IVandKey[0] = \
                                             addrObjPrev.binInitVect16.copy()
                  addrObj.createPrivKeyNextUnlock_IVandKey[1] = \
                                          addrObjPrev.binPrivKey32_Encr.copy()

                  addrObj.createPrivKeyNextUnlock_ChainDepth  = ChainDepth

         addrObj.unlock(self.kdfKey)
         if addrObj.chainIndex > -1: addrObjPrev = addrObj

         if needToSaveAddrAfterUnlock:
            updateLoc = addrObj.walletByteLoc 
            self.walletFileSafeUpdate( [[WLT_UPDATE_MODIFY, 
                                         addrObj.walletByteLoc,
                                         addrObj.serialize()]])

      self.isLocked = False
      LOGDEBUG('Unlock succeeded: %s', self.uniqueIDB58)

[po0kie]

in the signtx function there the unlock function are threaded seperatly as follows (just unlocking needed addresses):

Code:

 numInputs = len(txdp.pytxObj.inputs)
      wltAddr = []
      for index,txin in enumerate(txdp.pytxObj.inputs):
         scrType = txdp.scriptTypes[index]
         if scrType in CPP_TXOUT_STDSINGLESIG:
            scrAddr = txdp.inScrAddrList[index]
            addr160 = scrAddr[1:]
            if self.hasAddr(addr160) and self.addrMap[addr160].hasPrivKey():
               wltAddr.append( (self.addrMap[addr160], index, 0))

Hi,

1) Which is the recommend version for setting up a new (offline) wallet?
0.91.2 for creating & broadcasting and 0.90 for the offline one? I am afraid of the recent bugs.

2) I don't want to transfer the created & signed transactions by usb (ultra paranoid ). After I move the armory offline bundle to the offline machine and back upped the wallet I never want to have a cd/usb stick in the offline computer again.How large is the average transaction and how long do you think will it take to type it by hand? if it can be done in 10minutes I am totally okay with that.

3) Is the torrent blockchain downloader included in all new armory versions (linux, windows, mac os)? I am not sure if it works on Mac OS. I started Armory, than bitcoin-qt. As far I can tell it does download the blockchain only with bitcoin-qt.

Thanks!

Hi there,

I tried to perform a search for this, but didn't get any straight answers.  Can you launch/run Armory and also have it function as a full bitcoin node?  If this isn't possible...I think it should be.

Thanks,

Armory, requires a full node, so technically you are running a full node, but armory itself is not a full node.

1) For now old versions, even 0.8x can run as an offline signer. We highly recommend upgrading to 0.91.2, for the added security of the wallet sanity check on each run. Eventually, when we put out the multisig version, you'll have to upgrade, as the transaction distribution format has changed to accomodate for multisig. With 0.92, we'll ship the new wallet format, so then you'll have to upgrade to create the new wallets.

2) A single in with 2 outs (spend + change) is something like 65 bytes for the uncompressed the public key, 65 for the sig, about 25 bytes per outputs so give and take 180 bytes. At 2 characters per bytes (hex encoded) you should be able to do it under 10 minutes. There no signature on the way in of course, so that gives you an idea. Make sure to thouroughly verify the spend and change addresses. After 0.92, I should have enough time to finally complete the audio data channel.

3) Last time I checked, it doesnt work with OSX. Granted Im not sure how that part is evolving, ask Doug directly about that part.

There currently isnt a version of online Armory that doesnt require a full bitcoin node in the background. We will come up with a lite node eventually, but also a supernode.
