What would you like to see in armoryd?

[doug_armory]

Hi. As some of you already know, Armory has an analog vis-a-vis Bitcoin-Qt/BC Core. There's armoryd, which uses JSON-RPC to interface with bitcoind. armoryd is a useful tool. It also lacks some features. I've been asked to give armoryd some TLC.

I'd like to know what users would like to see in armoryd. I have a few ideas already but would love to know what others would find useful. Posts here are preferred but PMs are fine too.

Thanks!

I'm not a direct user of armoryd.py, but I list here's the first couple "obvious" ones:

• Multiple wallets with context swtiching "showwalletlist" and "selectwallet 2xT9gxNq"
• Add a call for creating unsigned transactions just like creating regular transactions.
• Add a call for signing such a transaction (can copy code from extras/cli_sign_txdp.py)

[doug_armory]

Thanks. I've been thinking about it the past couple of days and am slowly compiling a list of ideas.

Anybody else? If you haven't played with armoryd, give it a shot. It's a little bare-bones at the moment but it could be really useful for those of you who like to automate things and/or not deal with a GUI. If you can think of it and Armory already does it via the GUI, there's a decent chance it can be done.

Can we leave any kind of message in the blockchain when we send a transaction?

Hi there!

I am working since severl months on armoryd, I am on work and have not enough time to compare code files and i dont know which are implemented right now on Armoryd (current version)
here some functions which I have implemented:


Unsigned Transaction (but I use always same change address as fromAddress)

Can we leave any kind of message in the blockchain when we send a transaction?

I don't think Armory lets you do that. I can look into it.

Hi there!

I am working since severl months on armoryd, I am on work and have not enough time to compare code files and i dont know which are implemented right now on Armoryd (current version)
here some functions which I have implemented:

Thanks! I haven't looked at this code yet but will do so soon. What you wrote looks really useful. I've just been focusing on getting armoryd back to a reasonably robust state and adding some more expansive features.



Everyone: Here's a quick update. As mentioned above, armoryd has been getting a fine tuning. I've expanded a fair amount of functionality and removed some hacks that made armoryd difficult to use - if not impossible to use - out of the box. Among other things, I've added or greatly expanded:

-Lockbox support. This is still very rudimentary but you can create lockboxes.
-E-mail support. Would you like to, say, e-mail some people whenever an address receives money? You can do that now. Again, this is a bit rudimentary and may need fine tuning in the future, but the basic functionality is there.
-Add support for multiple wallets. At the moment, you can still only have one active wallet at a time, but you can load multiple wallets and switch wallet contexts.
-Get a list of UTXOs for the current wallet or for the wallet associated with a given address.
-When a new block arrives, a chain of functions can be executed if desired. The functions can also be removed.
-I'll look at po0kie's code soon and will probably add it as is appropriate.

If anybody has any more ideas, please let us know! I don't know what exactly will make it into 0.92 but I'll do my best to squeeze in as much as possible.

Is armoryd tied to bitcoind specifically, or can it be run against any full node implementation that is RPC compatible (btcd)?

Just like ArmoryQt, if you run Bitcoin Core manually, RPC isn't even used.  Armory connects to it as a peer.  So far, it does require access to the Core directory:  ~/.bitcoin/blocks/blk*.dat files to read the blockchain, but in the future we plan to remove that dependency and have it operate entirely over P2P messages.   Then it will easily allow remote Core instances.  And also anything else that allows the download of the full blockchain over P2P, not necessarily Bitcoin Core itself.

armoryd doesn't have an option to run Bitcoin Core automatically, but when you do this in ArmoryQt it does connect over RPC, but basically just to find out the synchronization state when you are initially downloading the blockchain.

I don't think it'd really be relevant in Armory itself since it kind of already does notify you of changes, if you have Armory open.  But I'd like to propose what this guy said as an additional feature for armoryd: http://bitcoin.stackexchange.com/questions/24387/listening-for-changes-to-my-own-wallet-in-the-blockchain

That feature is already present. Well, maybe not to the fullest extent possible, but armoryd can send email notifications under certain circumstances. I'll squeeze in what I can for the 0.92 release and will see about adding more features in a follow-up release.

Speaking of armoryd, I urge everyone who's interested to check it out when 0.92 is ready for testing. It has changed an awful lot in the past month and should prove to be quite useful. As always, feedback will be welcome.

Oh, awesome.  By the way, out of curiosity, do you need to have the full bitcoin client running to run armoryd, or can it access it remotely?  Just wondering, I'd love to host it on a webserver for an e-commerce site I have planned, but if I need to host the full blockchain to do it, I'm probably not going to bother.

As written, armoryd expects bitcoind to reside on the same server. I don't think one could easily employ a remote bitcoind solution. (It's certainly possible under Python, of course.) We may make such a setup easier to achieve in the future. It just hasn't been a focus for the 0.92 release.
