Bitcoin Armory is an open-source, full-node desktop wallet application designed for advanced Bitcoin power users, institutions, and developers who require enterprise-grade security. Originally launched in 2011 by Alan Reiner, it pioneered the foundational concepts of cold storage and air-gapped security infrastructure long before hardware wallets became mainstream. Core Features
Air-Gapped Cold Storage: You can generate and maintain private keys on an offline computer that never connects to the internet. It operates concurrently with an online “watching-only” wallet that tracks balances and handles transactions securely without risking your private keys.
Full-Node Reliance: Armory does not have its own network components. It hooks directly into Bitcoin Core to handle blockchain data verification and transaction broadcasting.
Multi-Signature Wallets: It supports distributed multi-sig security schemas, enabling institutional setups where transactions require signing by a majority of distributed users.
GPU-Resistant Encryption: The software utilizes robust cryptographic frameworks designed to protect wallet files from being brute-forced by high-speed hardware like graphic cards.
Permanent Paper Backups: It creates one-time printable backups that will safely recover all addresses generated by the wallet indefinitely. Architecture & Mechanics
