What Are Bitcoin Hardware Wallets?
A Bitcoin Signing Device, commonly referred to as a hardware wallet, is a specialized device designed to securely manage and store private keys. Unlike full-fledged Bitcoin wallets that possess chain state and can create transactions autonomously, signing devices strictly handle key management and transaction signatures. By framing it as a "signing" device, it underscores the act of authorizing or "signing off" on transactions, akin to personal endorsements in traditional finance. This distinction also sheds light on the limitations of non-signing wallets, like hosted or web wallets, which can restrict true ownership and the user's inherent ability to sign. For individuals prioritizing autonomy and security in their Bitcoin dealings, a Signing Device offers a robust solution.
