What is a Hardware Wallet?
A hardware wallet, a type of a cold wallet, is a physical electronic device specifically designed to protect an individual’s cryptocurrency by ensuring private keys are stored securely offline. This is crucial because private keys provide access to one’s crypto assets, and by being offline, they remain safe from potential online threats such as hacks, phishing attacks, and malware.
In contrast to software wallets, which are digital interfaces, hardware wallets act as fortresses, protecting against online vulnerabilities. While a software wallet can be seen as an email account, a hardware wallet is akin to a high-security safe, where the contents are safeguarded against external threats.
How does a Hardware wallet work?
When a transaction is initiated, the hardware wallet must be connected to a computer or a smartphone. The transaction details are then sent to the hardware wallet for signing. Once signed, the transaction is sent back to the online device, and from there, broadcasted to the blockchain. Throughout this process, the private key never leaves the hardware wallet, ensuring its utmost security.
|Initialization||Wallet is set up and a unique private key is generated.|
|Transaction Initiation||User decides to send/receive cryptocurrency.|
|Transaction Signing||Hardware wallet signs the transaction without revealing the private key.|
|Verification||Transaction details are verified on the hardware wallet’s screen.|
|Broadcast||Once signed, the transaction is sent back to the online device and broadcasted to the network.|
History of Hardware Wallets
The inception of hardware wallets can be traced back to the early days of cryptocurrencies when enthusiasts began searching for ways to keep their digital assets safe from increasing cyber threats. While software wallets (hot wallets) provided convenience, the vulnerabilities associated with being constantly connected to the internet led to a demand for offline storage solutions. This demand laid the foundation for the first crypto hardware wallets, which prioritized security above all else.
