Everything needed to create transactions can be managed from an online computer with a watching only wallet. All secret private key data is available only on the offline computer.
This greatly reduces the attack surface for an attacker attempting to steal bitcoins. By keeping all private-key data on the offline computer only someone with physical access to the offline computer can steal your Bitcoins. The actual process of creating a transaction and signing it with the offline computer can take less than a minute and then you can broadcast it to the network so Bitcoin miners can include it in a block.
Plus, Armory employs many security practices so that even if someone physically stole your offline system then it still may take centuries for them to get through the advanced wallet encryption! And multi-signature addresses are available using Lockboxes in a completely distributed way. Thus, there is no safer way to manage large sums of Bitcoins than with the best Bitcoin wallet, Armory! From the start Armory was designed to never compromise Bitcoin security.
Users completely control the generation and storage of the Bitcoin private keys. This wallet makes it harder to spy on your balance and payments by rotating addresses. You should still take care to use a new Bitcoin address each time you request payment. This wallet does not disclose information to peers on the network when receiving or sending a payment.
This wallet lets you setup and use Tor as a proxy to prevent attackers or Internet service providers from associating your payments with your IP address. This wallet gives you full control over fees. This wallet also provides fee suggestions based on current network conditions so that your transactions are confirmed in a timely manner without paying more than you have to. Bitcoin is different from what you know and use every day.
Before you start using Bitcoin for any serious transaction, be sure to read what you need to know and take appropriate steps to secure your wallet. Always remember that it is your responsibility to choose your wallet carefully and adopt good practices in order to protect your money. Ubuntu does not yet come pre-packaged with Bitcoin Core.
