Ledger hardware wallets are a set of multi-purpose wallets used to store private keys for cryptocurrency offline currencies. From this article, two hardware wallets are in operation: Ledger Nano S and Ledger Blue. Both wallets support 25 encryption blocks. The list includes prominent cryptocurrencies such as Bitcoin and Atrium, as well as more well-known items such as Vertcoin and Komodo.
Trading using cryptographic passwords requires the use of private encryption keys. But these keys, which are usually stored online, are prone to theft and hacking. Cryptocurrency users have created an alternative storage system. These include hot wallets (online), mobile wallets (smartphone wallets) and paper wallets (stored on paper).
Hardware wallets are a kind of offline storage. They are device-based, meaning that they use storage mechanisms such as USB drives to store private keys, making it difficult for hackers to access the key online.
Ledger Nano S is a USB storage wallet. While the Blue Ledger is a handheld device with a touch screen and USB and Bluetooth. These wallets enable users to perform a variety of tasks, including sending and receiving bitcoins from blockchains or running third-party applications on the device. For example, users can use wallets to execute two-factor global authentication on popular sites such as Google and Dropbox. Both wallets also use 20-word backup phrases, which you can use to access the user’s cryptocurrency if a device with a private key is stolen.
