Notes on putting Bitcoin Armory on a Raspberry Pi for Bitcoin cold storage

These are my notes as to what I had to do to get things to work since online instructions either didn't work or were missing things.
I'm using a B+ model and an 8GB SD card.
  1. I tried putting the image on from ColdPi. This doesn't work. The RPI won't boot. I don't know why and I can't troubleshoot it. http://coldpi.com/manuals/install-image.html
  2. Their other method (http://coldpi.com/manuals/install.html) uses a MUCH older version of Armory and doesn't have enough instructions.
  3. Go to Armory site and download the latest version https://bitcoinarmory.com/download/ Follow these instructions: https://www.armoryguide.com/OfflineInstallation.html

Problems:

What to do:
a) untar the offline bundle
b) try and verify the signatures (fail!)
c) install the debs: you can try to do it by running the script (via startx, but I'm doing it from the CLI: sudo dpkg -i *.deb
d) Instll the armory package: sudo tar -zvxf armory*tar.gz -C /
e) make the armory desktop launcher (copy the last section of the Install_DblClick_RunInTerminal.py)
f) Now you have to set it up to be offline:

 SystemSpecs = None try: raise SystemSpecs = GetSystemDetails() except: 
There is no other clear way of making Armory start in offline mode. You'd think that there would be some CLI parameter!
g) disable your networking in case you accidentally plug in the ethernet cable by running: "update-rc.d -f networking remove" . NOTE: This does not disable WiFi. I tried plugging in WiFi dongle and it still connected.
h) stop sshd from running on startup:type this in: sudo touch /etc/ssh/sshd_not_to_be_run

Trying to install armory bitcoin wallet on raspberry pi. [Help]

Hi I recently just bought my first raspberry pi (model a+) and have installed the latest version of raspbian on it. I am having issues however, with installing the armory application on it. I have been to the armory website and downloaded the latest offline version of armory for rasbian and then launched the install script on the pi. I believe that the script installed the application however, nothing happens when I launch the application. I have never used raspbian or any linux based operating systems before so please bare with me if I'm doing something really stupid. I assume that I am missing some other packages that need to be installed but I have no idea which ones. Armory runs on python on raspbian and I am not sure if I need to install some python packages or if they are pre-installed into the OS. I tried watching this tutorial: https://www.youtube.com/watch?v=32lovaPtZws and it was very straight forward however, the links to the packages and armory files are now dead. As I said I am a complete noob at raspbian so I would really appreciate any help possible with getting armory to launch on pi. Thanks!

A Guide to Keeping Keys Offline Using Armory +rPi

Hi Redditors.
I am going to post in this thread my experiences in getting my Desktop (Debian) machine running Armory in watch-only mode, and coupling that with an offline Raspberry Pi (which holds my private keys) for signing the transactions previously made in watch-only mode.
I actually compiled Armory from source directly on my Pi. This guide is probably more for the bitcoin 'power user', as to run Armory online, and broadcast the signed transactions, you need to have a bitcoin full node running (bitcoind).
Basic requirements:
Aimed-for Setup:
I'll post the guide in digestible sections...

Section 1

I should begin by saying I installed source code from git, and got Armory to build the DB on my desktop initially, WITHOUT creating a wallet.. (This allowed me to debug what was going on a little!)
Go to Bitcoin.org, select Armory..
It leads to a Download from Git:
https://github.com/goatpig/BitcoinArmory/releases
Followed the procedure for Linux Debian verify code, compile, install, all straight-forward..
Began by running bitcoind, and telling Armory where to find it. This is the command I used, obviously it was all on one line and didn't include the arrows/explanations!:
python ArmoryQt.py \ --satoshi-datadir=/BlockChain/chain20180414/blocks \ # <-----(where my bitcoind blocks live) --datadir=/ArmoryDataDi \ # <-----(this is instead of ~/.armory) --dbdir=/ArmoryDataDidatabases # <-------(again, non std. place used for Armory's databases.. my choice.) 
So, on the Desktop, after the initial "build databases"
(NB the initial "Build Databases" took about 1.5h and my two CPUs were maxed the whole time, Temps up to 62C. Not ideal; Im not in a rush!)
I then wanted to import a watch-only wallet.
Before I did this, I took a full backup of the Armory data dir:
/ArmoryDataDi
(or ~/.armory in a default installation).
I'd hate to have to make Armory do another full sync with the bitcoind node!

Section 2

Next step: offline wallet (with Private Keys) is on a Raspberry Pi.
I downloaded the source and managed to compile it on the pi itself! :)
Though there were some gymnastics needed to setup the Pi.
My Pi is running Raspbian based on Wheezy.. quite old!
I did the following on the Pi:
apt-get update apt-get upgrade (<---took about an hour!) apt-get install autotools-dev apt-get install autoconf 
Then I followed the instructions exactly as I had done for my Debian Desktop machine, EXCEPT:
I had to increase the Pi's swap space. I upped it from 100Mb to 400Mb.
The compilation took 7 hours, and my poor SD card got a thrashing.
But after compilation, I put the Swap back to 100Mb and Armory runs ok with about 150Mb of memory (no swap needed).
Swap increase on the Pi:
use your favourite editor, and open the file /etc/dphys-swapfile
add/change the following line:
CONF_SWAPSIZE=400 
Then, REBOOT the Pi:
sudo shutdown -h -P now 
Once the compilation was done on the Pi, put the swap back, rebooted and created an Armory wallet.
I added manual entropy and upped the encryption 'time' from 250ms to 2500ms - since the Pi is slow, but I'll be happy to wait for more iterations in the Key Derivation Function.
Once the wallet was created, it obviously prompts you for backup.
I want to add a private key of my own (i.e. import), so don't do the backup until this is over.
I import my Private Key, and Armory checks that this corresponds to a Public Key, which I check is correct.
This is the point now where the Pi storage medium (e.g an SD card) has to be properly destroyed if you ever get rid of it.
I had thought that now would be a good time to decide if your new wallet will generate Segwit receiving addresses, and also addresses used to receive 'change' after a transaction..
But it seems Armory WON'T let you switch to P2SH-P2WPKH unless your Armory is connected to a node offering "WITNESS" service.
Obviously, my Pi is offline and will never connect to a node, so the following will not work on the Pi:
NB: I thought about setting this on the Debian "watch-only" wallet, but that would surely mean doom, as the Pi would not know about those addresses and backups might not keep them.. who knows...
So, end result:- no segwit for me just yet in my offline funds.

--If anyone can offer a solution to this, I'd be very grateful--

Section 3

Ok, now this is a good point to back up your wallet on the Pi. It has your imported keys. I choose a Digital Backup - and put it on a USB key, which will never touch the internet and will be stored off-site. I also chose to encrypt it, because I'm good with passwords..
NB: The Armory paper backup will NOT back up your imported private keys, so keep those somewhere if you're not sweeping them. It would be prudent to have an Armory paper backup anyway, but remember it will likely NOT help you with that imported key.
Now for the watch-only copy of the wallet. I want to get the "watch-only" version onto my Desktop Debian machine.
On the Pi, I created (exported to a USB key) a "watching-only" copy of my wallet.
I would use the RECOMMENDED approach, export the "Entire Wallet File".
As you will see below, I initially exported only the ROOT data, which will NOT capture the watching-only part of the Private Key I entered manually above (i.e. the public Key!).
Now, back on the Debian Desktop machine...
I stopped all my crontab jobs; just give Armory uninterrupted CPU/memory/disk...
I also stopped bitcoind and made a backup prior to any watch-only wallet being imported.
I already made a backup of Armory on my Desktop, before any wallet import.
(this was needed, as I made a mistake.. see below)
So on the Debian Desktop machine, I begin by firing up bitcoind.
my command for this is:
./bitcoind -daemon -datadir=/BlockChain/chain20180414 -dbcache=400 -maxmempool=400 

Section 4

I try running Armory like this:
(I'm actually starting Armory from a script - StartArm.sh)
Inside the script StartArm.sh, it has the line:
python ArmoryQt.py --ram-usage=4 --satoshi-datadir=/BlockChain/chain20180414/blocks --datadir=/ArmoryDataDi --dbdir=/ArmoryDataDidatabases 
I know from bitter experience that doing a scan over the blockchain for a new wallet takes a looong time and a lot of CPU, and I'd like it to play nicely; not gobble all the memory and swap and run my 2xCPUs both at 100% for four hours...
So... I aim to run with --ram-usage=X and --thread-count=X
(For me in the end, X=1 but I began with X=4)
I began with --ram-usage=4 (<--- = 4x128Mb)
The result is below...
TypeError: cannot concatenate 'str' and 'int' objects 
It didn't recognise the ram-usage and carried on, crippling my Debian desktop PC.
This is where it gets dangerous; Armory can gobble so much memory and CPU that the windowing environment can cease up, and it can take over 30 minutes just to exit nicely from bitcoind and ArmoryDB.
So, I ssh to the machine from another computer, and keep an eye on it with the command
"free -h" 
I'd also be able to do a "sudo reboot now" if needed from here.

Section 5

So, trying to get my --ram-usage command recognised, I tried this line (added quotes):
python ArmoryQt.py --ram-usage="4" --satoshi-datadir=/BlockChain/chain20180414/blocks --datadir=/ArmoryDataDi --dbdir=/ArmoryDataDidatabases 
But no, same error...
Loading Armory Engine: Armory Version: 0.96.4 Armory Build: None PyBtcWallet Version: 1.35 Detected Operating system: Linux OS Variant : ('debian', '9.4', '') User home-directory : /home/ Satoshi BTC directory : /BlockChain/chain20180414 Armory home dir : /ArmoryDataDi ArmoryDB directory : /ArmoryDataDidatabases Armory settings file : /ArmoryDataDiArmorySettings.txt Armory log file : /ArmoryDataDiarmorylog.txt Do wallet checking : True (ERROR) ArmoryUtils.py:3723 - Unsupported language specified. Defaulting to English (en) (ERROR) ArmoryQt.py:1833 - Failed to start Armory database: cannot concatenate 'str' and 'int' objects Traceback (most recent call last): File "ArmoryQt.py", line 1808, in startArmoryDBIfNecessary TheSDM.spawnDB(str(ARMORY_HOME_DIR), TheBDM.armoryDBDir) File "/BitcoinArmory/SDM.py", line 387, in spawnDB pargs.append('--ram-usage=' + ARMORY_RAM_USAGE) TypeError: cannot concatenate 'str' and 'int' objects 

Section 6

So, I edit the Armory python file SDM.py:
if ARMORY_RAM_USAGE != -1: pargs.append('--ram-usage=4') #COMMENTED THIS, SO I CAN HARDCODE =4 # ' + ARMORY_RAM_USAGE) 
Running it, I now have acknowledgement of the --ram-usage=4:
(WARNING) SDM.py:400 - Spawning DB with command: /BitcoinArmory/ArmoryDB --db-type="DB_FULL" --cookie --satoshi-datadir="/BlockChain/chain20180414/blocks" --datadir="/ArmoryDataDi" --dbdir="/ArmoryDataDidatabases" --ram-usage=4 
Also, even with ram-usage=4, it used too much memory, so I told it to quit.
It took over 30 minutes to stop semi-nicely. The last thing it reported was:
ERROR - 00:25:21: (StringSockets.cpp:351) FcgiSocket::writeAndRead FcgiError: unexpected fcgi header version 
But that didn't seem to matter or corrupt the Armory Database, so I think it's ok.
So, I get brave and change SDM.py as below, and I make sure my script has a command line for --ram-usage="ABCDE" and --thread-count="FGHIJ"; the logic being that these strings "ABCDE" will pass the IF criteria below, and my hardcoded values will be used...
if ARMORY_RAM_USAGE != -1: pargs.append('--ram-usage=1') #COMMENTED THIS, SO I CAN HARDCODE =1 # ' + ARMORY_RAM_USAGE) if ARMORY_THREAD_COUNT != -1 pargs.append('--thread-count=1') #COMMENTED THIS, SO I CAN HARDCODE =1 #' + ARMORY_THREAD_COUNT) 
So, as usual, I use my script and start this with: ./StartArm.sh
(which uses command line:)
python ArmoryQt.py --ram-usage="ABCDE" --thread-count="FGHIJ" --satoshi-datadir=/BlockChain/chain20180414/blocks --datadir=/ArmoryDataDi --dbdir=/ArmoryDataDidatabases 
(this forces it to use my hard-coded values in SDM.py...)
So, this is the command which it reports that it starts with:
(WARNING) SDM.py:400 - Spawning DB with command: /BitcoinArmory/ArmoryDB --db-type="DB_FULL" --cookie --satoshi-datadir="/BlockChain/chain20180414/blocks" --datadir="/ArmoryDataDi" --dbdir="/ArmoryDataDidatabases" --ram-usage=1 --thread-count=1 
Again, this is where it gets dangerous; Armory can gobble so much memory and CPU that the windowing environment can cease up. So I ssh to the machine and keep an eye on it with:
"free -h" 

Section 7

So, on the Debian Desktop PC, I inserted the USB stick with the watch-only wallet I exported from the Pi.
Start Armory...
Import "Entire Wallet File" watch-only copy.
Wait 4 hours..
YAY!!!
After running Armory for about 30m, the memory usage dropped by 400m... wierd...
It took ~2 hours to get 40% completion.
After 3.5 hours it's almost there...
The memory went up to about 1.7Gb in use and 900Mb of Swap, but the machine remained fairly responsive throughout, apart from a few (10?) periods at the start, where it appeared to freeze for 10-30s at a time.
(That's where my ssh session came in handy - I could check the machine was still ok with a "free -h" command)
Now, I can:
Create an unsigned transaction on my Desktop,
Save the tx to USB stick,
Move to the Pi,
Sign the tx,
Move back to the Desktop,
Broadcast the signed tx.

Section 8

My initial Mistake:
This caused me to have to roll-back my Armory database, using the backup. so you should try to avoid doing this..
On the Pi, I exported only the ROOT data, which will NOT capture the watching-only part of the Private Key
It is RECOMMENDED to use the Digital Export of Entire Wallet File from the Pi when making a watch-only copy. If you just export just the "ROOT data", not the "Entire Wallet File", you'll have problems if you used an imported Private Key in the offline wallet, like I did.
Using the ROOT data text import, after it finished... my balance was zero. So,. I tried a Help->Rescan Balance (Restart Armory, takes 1minute to get back up and running) No Luck. Still zero balance.
So, I try Rescan Databases.. This will take longer. Nah.. no luck.
So, I tried again, thinking it might be to do with the fact that I imported the text "root data" stuff, instead of following the (Recommended) export of watching-wallet file.
So, I used my Armory backup, and wound back the ArmoryDataDi to the point before the install of the (zero balance) wallet. (you should not need to do this, as you will hopefully use the RECOMMENDED approach of exporting the "Entire Wallet File"!)

[Guide] Setting up Trezor + Electrum 2.02beta + armory on a Raspberry Pi 2. Cold offline signing for $40

Having just received my Pi 2, I am happy to report that a fresh Raspbian install, on an 8 GB Class 10 MicroSD card : Electrum / Armory / Trezor / BTChip all work with my Single Board Computer setup script (it also works for Pi B, Pi B+ Raspbian and BeagleBone Black Debian & ubuntu, also tested on Odroid C1 Ubuntu 14.4)
The full "!" installation takes about 40 mins on Pi 2, which is at least twice as fast as on the Pi B+ / BBB

[Question] Pros/Cons of offline bitcoin storage "cold storage"

I've been looking into creating an offline bitcoin storage device via raspberryPI + Armory.
I was wondering what i should watch out for and any advice to someone who isn't the most tech savvy but can get around.
One specific question i had was: What would happens in the situation where you loose your cold storage device or it fails on you? do you loose all your bitcoins? even if you have a paperbackup?
edit:Also is it a good idea to create a wallet on a raspberryPI or is there a more advised solution?

Need Help - Reindexing Blockchain

I need help here, for the last 5 days in a row I've been trying to download the Blockchain on Bitcoin-qt so that I can run Armory with offline transactions from my Raspberry Pi. Everything is already setup on my RPi, now I just need to download the block chain on my Online Armory client. This is proving harder than it looks…
I'm running my Online Armory client on Windows 8 OS booting from Virtualbox on my Mac OSX. The reason I have to use virtual box is the latest version of Armory for Mac glitches out and doesn't work for me.
So I've downloaded the bootstrap and placed it in the correct location and ran Bitcoin-qt, at this point (after 20-30 separate attempts) I've downloaded up to around "15 weeks behind" but once I get to around October 22nd, 2013 the blocks begin indexing extremely slow. I've tried booting the qt client with -reindex commands several times, I've tried booting qt with the -dbcache=1000 commands several times, and unfortunately I STILL have not completely downloading the block chain and I'm about to fucking murder someone because it should not be this difficult to download the block chain!!
So each time when I'm downloading the block chain it gets interrupted by one of two things. FIRST, sometimes around 15-14 weeks behind the qt client just "stops responding" and windows give me the option to close it out. After I close it and try to reboot, the database is unable to be found and I have to run the -reindex command and start all over. The SECOND thing that happens, is my Windows 8 OS running on virtual box will randomly go to a new screen that says "your product key is not correct, please enter a new one or buy another"… even though I initially entered a working product key when I first installed the OS and when I try to reenter another working product key (I've tried dozens) none of them work. So this blue screen interrupts my block chain download and at this point I haven't got past "15 weeks behind".
I've tried saving snapshots so that when the qt client stops responding or the windows 8 OS goes to that blue screen that says "reenter product key" I can restore from my last snapshot, but when i restore from an old snapshot one of those two problems continues to occur and prevents me from downloading any further than block 265502.
At this point I'm for a loss. I've done hours of searching and can't figure out how to fix this shit… can somebody help me out?

help with scenario

I am Bitcoin noob, I do not know how to do it, but here is what I want to do:
For cold wallet I have offline Raspberry Pi, and I need some wallet application on it, that can sign transactions. What are some of those wallet apps that can sign transactions? (Armour is one, from bitcoin.org) Than I need online computer, with wallet application - does HOT wallet have to be the same wallet as cold storage wallet?
Next, I need some Bitcoins, that I attend to buy for cash, from ATM. In order to do that I will scrubble my bitcoin address on piece of paper and type it in ATM. Now, where do I get this my bitcoin address? From my cold or hot wallet? Further on, when I came home, how can I put my bought bitcoins into my cold wallet?
So, what are the right steps to produce this kind of scenario?
Note, as long as I am a noob, I am asking about more secure set up - which are not explained in newcomers section - in fact, I am turning here for your help because I have not find tutorials on how to do a secure COLD way, or getting bitcoins at atm from a piece of paper.
Most of my inspiration cames from here: https://bitcoin.org/en/secure-your-wallet "Offline transaction signing This approach involves having two computers sharing some parts of the same wallet. The first one must be disconnected from any network. It is the only one that holds the entire wallet and is able to sign transactions. The second computer is connected to the network and only have a watching wallet that can only create unsigned transactions. This way, you can securely issue new transactions with the following steps. -Create a new transaction on the online computer and save it on an USB key. -Sign the transaction with the offline computer. -Send the signed transaction with the online computer.
Because the computer that is connected to the network cannot sign transactions, it cannot be used to withdraw any funds if it is compromised. Armory can be used to do offline transaction signature."
Thank you
