Bitcoin-qt Ubuntu 10.04 / Dogecoin hashrate wallet

The biggest priority as far as a Bitcoin user is concerned is security, and MultiBit bitcoin client is a perfect blend of security and functionality. MultiBit is free to download, is very easy to install and is open source (MIT license). It is a very good wallet management software for Bitcoin beginners with many advanced features such as the support for multiple wallets, locally stored encrypted private keys etc. Do the following to install latest MultiBit version in Ubuntu.

Open Terminal (CTRL + ALT + T) and CD into your Downloads folder.

cd ~/Downloads/

Make the downloaded file executable.

chmod +x multibit-0.5.16-linux.jar

Now, to install MultiBit, you need to have the latest Java version installed.

sudo apt-get install openjdk-7-jdk

Done. Now let's do the installation. Copy-paste the following command into Terminal.

java -jar multibit-0.5.16-linux.jar

An installation wizard will pop up walking you through the required steps. Finish it and you're ready to go. MultiBit installation has been completed successfully.

Armory is a Bitcoin wallet management platform which is designed from the ground up to provide the highest level of security to savvy Bitcoin users. It is intended for the super-paranoid among you, who don't like to take any chances when it comes to Bitcoin management.

Apart from the usual set of features like support for multiple wallets and such, Armory has many advanced functionalities like offline wallets, built-in dialog for printing permanent copies of your wallet, three different user modes for beginners and advanced users alike and so on. The only draw-back is the fact that, Armory needs either bitcoin-qt or bitcoind (bitcoin-qt without GUI) to work, which inturn translates into significant disk-space usage. According to the Armory devs, it is not possible to remove this dependency without compromising on the security and privacy that Armory currently offers.

Armory is open-source (licensed under the AGPL V3) and it's available for free download and use. Luckily for Ubuntu users, well tested DEB packages are available for easy installation of Armory Bitcoin client. Here's what you need to do.

And double-click to install it. Ubuntu Software Center will do the rest. Before installing though, I would recommend you to verify the authenticity of the downloaded Armory DEB package by following the instructions given in the download page.

And then there's Bitcoin-Qt, the official Bitcoin client which acts as the backbone of Bitcoin's network security. As we noted earlier, a client like Armory needs Bitcoin-Qt or its headless counterpart in order to run properly. Since Bitcoin-Qt is run by the majority of the nodes, it is well-maintained, thoroughly tested and reviewed, and has fool-proof security. Though the functionalities are more basic when compared to Armory or MultiBit.
