Ledger Blue Description 2020
The Ledger Wallet Blue is the latest hardware wallet from Ledger and convinces with its even easier operation. This model now also has a touch screen and improved connectivity via Bluetooth.
Ledger Blue makes hardware wallets even more convenient
Ledger Blue is the most advanced hardware security equipment on the market. It has multi-application execution and combines enterprise-level crypto capabilities with a lightweight handheld device. Manufactured and developed in France, it meets the highest standards. It is built around a secure element, with a touch screen and USB & Bluetooth connectivity.
A powerful and flexible device
Ledger Blue is the latest product from Ledger, which has been developed over two years of research and development. This high-end device embeds a large touch screen to securely manage transactions and complex, intelligent contracts. Its smooth, yet rugged housing incorporates best-in-class technology built on the Blockchain Open Ledger (BOLOS) platform.
The hardware features
The Blue Ledger is based on a dual-chip architecture that integrates an ST31 SecureElement and an STM32 microcontroller. It has a touch screen with LED backlighting for easy navigation and transaction validation. It is powered by a Lipo battery and communicates with USB or Bluetooth devices.
Each app has its own security area
Thanks to its modular architecture, the Ledger Blue executes several dedicated companion apps in full isolation via the firmware. The strong security model allows you to add new cryptocurrencies or apps without endangering the master key. Transaction integrity is ensured by the WYSIWYS paradigm (What You See Is What You Sign). The flexibility of the device allows the user to use the device in the firmware that can support any type of block chain.

FAQ 4Ask your own question
That is not a problem. You can restore your accounts to a new hardware wallet using the recovery key you wrote down when you set it up.
Most wallets support more than just one cryptocurrency, but only generate one backup. Nevertheless, this one backup is sufficient to restore all cryptocurrencies as all private keys of the different wallets result from the seed that is backed up as a backup during setup.
Hardware Wallets such as the Ledger Nano X, TREZOR Model T, BitBox02 or KeepKey all work according to the same principle. They are a special form of a so-called wallet, which is used to manage cryptocurrencies. A hardware wallet is a physical device that securely and inisolationly generates the private keys to the cryptocurrencies. Due to the extra hardware, they have some advantages over software wallets:
- private keys are often stored in a protected area of a microcontroller and cannot be transmitted in plain text from the device
- immune to computer viruses stealing from software wallets
- can be used securely and interactively, private keys never need to touch potentially vulnerable software
- the software is open source in most cases, so that the user can validate the entire operation of the device.
However, it is important to understand that hardware wallets are a high-quality goal and depend on various assumptions that apply to maintaining security. They are not a miracle weapon, and there are several realistic ways to hack a hardware wallet Especially if someone has physical access to the device.
A new cryptocurrency is rarely supported directly by a hardware wallet at the beginning. However, most providers such as Ledger or TREZOR are constantly working to support new cryptocurrencies. Therefore, it is often worth waiting until the desired currency is supported by your hardware wallet.
