Armory
Armory is an advanced Bitcoin client that expands its features for Bitcoin power users. It offers many backup and encryption features, and it allows secure cold-storage on offline computers.
Features
-
Full Node
Some wallets fully validate transactions and blocks. Almost all full nodes help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes. -
Legacy Addresses
Most wallets have the ability to send and receive with legacy bitcoin addresses. Legacy addresses start with 1 or 3 (as opposed to starting with bc1). Without legacy address support, you may not be able to receive bitcoin from older wallets or exchanges.
-
Multisig
Some wallets have the ability to require more than one key to authorize a transaction. This can be used to divide responsibility and control over multiple parties.
-
SegWit
Some wallets support SegWit, which uses blockchain space more efficiently. This helps reduce fees paid by helping the Bitcoin network scale and sets the foundation for second layer solutions such as the Lightning Network.
Criteria
Validation
Full validation
This wallet requires you to install full node software that validates and relays transactions on the Bitcoin network. This means no trust in a third party is required when verifying payments. Full nodes provide the highest level of security and are essential to protecting the network. However, they require more space (over 750GB), bandwidth, and a longer initial synchronization time.
Transparency
Basic transparency
The developers of this wallet publish the source code for the client. This means any developer in the world can audit the code. However, you still need to trust developers of this wallet when installing or updating the final software because it was not built deterministically like Bitcoin Core.
Environment
Vulnerable environment
This wallet can be loaded on computers which are vulnerable to malware. Securing your computer, using a strong passphrase, moving most of your funds to cold storage, or enabling two-factor authentication can make it harder to steal your bitcoins.
Privacy
Improved privacy
Fees
Full control over fees
This wallet gives you full control over fees. This means that this wallet allows changing the fees after funds are sent using RBF or CPFP. 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.
