Hi!

First of all: Amazing work done by Armory Dev's!

I am working with the Daemon (extending it at moment to support Tx Offline Signing, and Broadcasting)

And i got a Little problem at the moment, maybe some of the Devs can point me to the right direction to get it working.

The Broadcast is nearly ready to use in ArmoryD, the problem I got is:
New Transaction Requests over the same SourceAddress of the previous Tx will fail until the BDM gets notified about Confirmations
from BitcoinD.

Its like he want to spent the same TxInputs and then the Tx will fail in Broadcast. I saw ArmoryQT maintaining a combinedLedger.
(appending ZeroConf Ledger Entries to the combinedLedger)
But I have not see any relation to the BDM with the combinedLedger (maybe i am missing something, Its the first Project i am touching python.)

Or How ArmoryQT get it working to not fail on next Tx’s when the previous Tx’s isn’t already +1 Confirmation?
It seems to me that ArmoryQt “makes in some way a manual sync” to be able to realize a next TX.

Any point to direct me where I can follow the needs?

Thanks!

poOkie, I'm not sure what exactly the problem. It sounds like you might be running into the issue of making multiple offline tx and trying to sign them without first broadcasting one of them. Armory currently can't handle this situation, and you will have to create-sign-broadcast a tx before you can create the next tx (you can create the next tx, though it will probably be invalid).

Btw, there's a script the in extras directory called "cli_sign_txdp.py" which has example code for you. You may have found that, or may have already reimplemented it. Just wanted you to see it.

I think all the needed stuff is in the ArmoryQT Heartbeat.
But I am not really aware which functions are necessary to be called to make it "temporarily sync" until new confirmations
arrive.

Or maybe I am totally wrong

As far as I know armory doesn't use rpc like that, it reads the database natively and has its own parser which you could borrow

So, I know the Armory developers are working on Trezor integration, etc. But I was wondering if stealth addresses and CoinJoin via the Armory client are in any sort of planning stage? Rather than doing these things manually, which is a hassle, it would be nice if it was EZ button type of implementation.

Appreciate all the hard work on Armory!

I can't speak for the Armory devs, but one nice thing about implementing stealth addresses in Armory is that it already has the machinery to scan the blockchain; you could easily use stealth at the highest privacy level where any stealth tx that's sent could be going to you. (zero-filtering)

It's something to consider about Armory in general: because it can work so easily with a local full-node you always have excellent privacy with regard to the contents of your wallet. All the queries are local, so info on what coins are in your wallet never leaves your machine. That's much better than SPV clients like Android Wallet where every peer you connect to learns statistical info narrowing down your addresses to within about one in 10,000 or so, or Electrum which currently just tells peers what addresses are in your wallet.

I'm very interested in this feature. It's just that it still sounds very theoretical at the moment. I'm also concerned about how much computation it will be to track the addresses ... ECDH calculations aren't cheap. I guess I'm still in a waiting mode, implementing other things while I wait for this to be ironed out (I don't have much to contribute to the discussion, though I have spent a lot of time thinking about how to get the same benefits without all the ECDH calcs).

Peter: Btw, I'm working on P2SH support right now. You will be able to test it on 0.91-dev in the next couple days. In fact, it seems to be working right now, on the p2shout branch -- you can try it right now, though I wouldn't do anything other than testnet.

As part of the update, I modified the PyTxDistProposal::createFromTxOutSelection() method to take any arbitrary list of script-value pairs, instead of just hash160 values. Right now, it will error out if you supply it something other than an P2PubKeyHash or P2SH, but that could be modified locally to create a tx with any arbitrary output scripts. As long as all the inputs are standard UTXOs, you can create such a tx and sign it no problem (have fun getting it mined, though).

Anyway, as something I myself would use, I'll offer a 1BTC bounty to get stealth address support in Armory. Contact me if you're interested in making it happen and we'll work out the specifics between myself and the Armory devs. (they're eligible too of course)

Coinjoin requires networking code which they avoid.

You can see all the current active (and unactive) command line args here, with their associated help comments.

Perfect

So there's 3 directories to be aware of.
And 3 connections, files, peer and rpc.

Has anyone successful changed Armory's appdata path on windows?

From https://bitcoinarmory.com/about/armory-and-bitcoin-qt/
"If you do this, then you will need to start Armory with the exact same path in “–satoshi-datadir=C:\path\to\new\location“."

"–satoshi-datadir=C:\path\to\new\location" : ignores the path and scans the db to default
"-satoshi-datadir=C:\path\to\new\location" : error: ArmoryQt.exe: error: no such option: -s

--satoshi-datadir=F:\Bitcoin --dbdir=F:\Armory

This worked.

Thanks, the docs are fucked up. No clue where I even learned that.

Every time I tried to send bitcoins, Armory crashes and it's rampant. Seriously, when are you going to fix it?! And every time it crash, it takes 20 minutes for bitcoin to scan transaction history - it's a fuking waste of time.

Are you using an older version of Armory that you create offline transactions from? The rescan on crash is fixed for 0.91

Can you PLEASE provide the download link? Or maybe update the download page via https://bitcoinarmory.com/download/

You need to address your issue with software update.. it's taking too long.

Maybe you should donate

That's in the 0.91-dev branch on github. Still a few weeks until we release this officially. The team is in the process of fixing the known comon bugs in this branch.

0.90. I don't see 0.91 via download page. Sigh...

========================================

Latest version: 0.90-beta:
» Version 0.90-beta for Windows Vista, 7, 8 (Both 32- and 64-bit)
» Version 0.90-beta: Signed hashes of all installers . Verify against our offline signing key (0×98832223).
[for WindowsXP, use 0.88.1-beta or wait for the 0.91-beta release]
In addition to the first-time Bitcoin-Qt/bitcoind synchronization step, Armory will also build its own set of databases the first time. This will take between 30 min and 3 hours depending on your system. It is recommended you do not interrupt this step. After it completes, subsequent loads of Armory will usually be under 30 seconds.

=========================================

0.91 isn't out.. if you have the download link, please do share.
