Here are the Alexandrite Raspberry Pi wallets (headless and Qt) for Raspbian Jessie (v8) as well as a blockchain snapshot. The wallet has been tested on both a Pi2 and Pi3. Since Alexandrite has a great appeal for staking, it makes sense to stake on a Pi at low electricity cost.
Important:
1) Always backup your wallet.dat first before you do anything
2) The wallets were built on Raspberry Pi2/3 (ARM) running Raspbian Jessie (v8) and the instructions and scripts assume you are running as user "pi". It is a pre-requisite to have Jessie installed on your Pi micro-SD card. You can find instructions of how to do this on
https://www.raspberrypi.org/downloads/ by either installing n00bs and selecting your OS or by downloading the image of the OS. NB! It is important that if you do a fresh install from an older Jessie image, that you first expand your file system with raspi-config. It is the first option in the menu. The default image they provide installs a partition of about 3.5GB and it needs to be expanded to 8GB or you will not have enough space for the installation. However, if you use the later Jessie image from May 2016, the file system will be expanded automatically. It is furthermore always a good idea to select the boot options in raspi-config to boot to a command prompt with authentication. You can then start the graphical desktop with "startx" manually. This helps with issues during upgrades.
3) The installation script installs the required dependencies automatically. If you have not done a recent upgrade, you might be presented with a screen of text during the Mozilla security certificate upgrade. If this happens, just scroll down and press "q" and the installation will continue.
4) Installation directory where the binaries are installed is ~/opt/alex or /home/pi/opt/alex
5) To run the wallets after installation go to the directory with the wallets and run the wallet file - ./Alexandrited for the headless wallet at the command line or click on the Alexandrite icon on the desktop or run the Alexandrite-Qt wallet file.
6) An Internet connection is required for the installation
7) You need at least an 8GB memory card for the wallet.
8.) The installation itself takes about 45min on an out-of-the-box Pi.
9) You cannot just download the dynamic wallets, you have to run the script to get the dependencies as well else it will not run.
10) The installation script enables the ufw firewall by default, but does not force any special rules. The wallet still works this way with the port blocked. If however you want to enable it to become a fully functional node, un-comment the ufw lines in the script and add the ports you want open (19531 for Alex) and run it again or easier, enable it manually by running the command "sudo ufw enable 19531" at the command line.
11) Always verify the checksums when you download files to make sure it was downloaded ok. To verify the checksums on your Pi, go to the ~/opt/alex folder and execute sha256sum <filename> and md5sum <filename> and compare the values with the values in the checksums.txt file.
12) The Alexandrite wallet uses a bootstrap.dat file which is installed automatically by the script up to block 8552.
Instructions to use the headless command line daemon wallet:
1) The installation script creates an Alexandrite.conf file with the startup settings in it. Go to the folder with the binaries ~/opt/alex and enter ./Alexandrited in a terminal window or at the command line to start the server
2) After the wallet has started and loaded the blockchain (give it a minute or so) you can enter the normal wallet commands that you would as in a Windows debug console preceded with ./Alexandrited eg. "./Alexandrited getinfo".
3) Remember to always make a backup of your wallet.dat file before you do anything like encrypting it
4) To encrypt your wallet run the command ./Alexandrited encryptwallet <yourpassword>
5) Once you have the wallet running, blockchain loaded and your wallet with coins on the Pi, then you can kickstart staking by executing ./Alexandrited walletpassphrase <yourwalletpassword> 99999999 true
Instructions to use the Qt wallet:
1) The wallet works exactly the same as the one in Windows.
To kickstart the installation execute the following commands at the command prompt or in a terminal window on your Pi.
wget https://bitbucket.org/jc12345/alex/downloads/alex_installation_pi.sh && chmod +x alex_installation_pi.sh && ./alex_installation_pi.sh && rm -f alex_installation_pi*
