Hardware wallets are the best balance between high security and ease of use. They are designed from the bottom to be a very small device that can only be used as a wallet that nothing else can do. You can’t install any software that’s safe from computer security vulnerabilities and online thieves, making them more secure. Because you can back up, if your device is lost, your money can still be recovered.
To this day, no hardware wallet has been put into production, but soon there will be:
The Trezor wallet signed the deal via an ARM microcontroller, 128KB OF RAM and a hardware random number generator, and users can interact with the device via a 0.96-inch OLED monochrome display with two keys to cancel or agree to a transaction.
Bitcoin protocols use the private key to sign transactions, which ensures that only the real owner of the address can use the funds. Trezor uses a series of 12 random characters to generate private keys that allow users to regenerate the wallet with those 12 random characters after it has been lost or stolen. Wallet uses open source software that allows users to easily review code to ensure that the program is absolutely safe and reliable.
