As announced back in May, we’ve been working on a firmware update for the Ledger Blue. Today, we’re pleased to announce the release of firmware 2.1 for the Ledger Blue, available in the Ledger Manager.
This update makes a series of security, accessibility and functionality improvements, including a reset feature, faster pin changes, application behaviour checks and hidden accounts through the use of a passphrase. The Ledger Blue app catalog has been expanded, and the Ledger Blue can now support up to 11 apps at the same time.
A batch of 10,000 Ledger Blue will shortly be made available exclusively on the official Ledger website for 229 EUR (without tax) and will carry the firmware version 2.1, released today.
The Ledger Blue remains a key part of Ledger’s product range, for consumers and enterprises, playing an essential role in the Ledger Vault enterprise security offering.

An improved user experience

The features introduced in firmware version 2.1 aim to simplify the Ledger Blue user experience:
PIN code change: Directly change the PIN code from the Ledger Blue settings menu.
Reset device: Ledger Blue users can now reset their device from the settings menu.
Recovery phrase verification: During initialization process, users will save their 24-word recovery phrase. From now on, all 24 words of the recovery phrase have to be confirmed.

Larger app catalog and storage efficiency

Device Apps: It’s now possible to install up to 11 apps on the Ledger Blue. Third party app developers are encouraged to add Ledger Blue support to their apps.
Supported device apps: The Ledger Blue is now able to support more crypto assets – including:

• Bitcoin (BTC)
• Bitcoin Cash (BCH)
• Bitcoin Gold (BTG)
• Bitcoin Private (BTCP)
• Dash (DASH)
• Digibyte (DGB)
• Dogecoin (DOGE)
• Ethereum (ETH)
• Ethereum Classic (ETC)
• Expanse (EXP)
• Hcash (HSR)
• Komodo (KMD)
• Litecoin (LTC)
• Peercoin (PPC)
• PivX (PIVX)
• PosW (POSW)
• Qtum (QTUM)
• Ripple (XRP)
• Stealth (XST)
• Stellar (XLM)
• Stratis (STRAT)
• Ubiq (UBQ)
• Vertcoin (VTC)
• Viacoin (VIA)
• Zcash (ZEC)
• Zencash (ZEN)

Third party applications, however, will only work if the developer has created a specific Ledger Blue version of the app.

New layers of security

We’ve made a series of improvements to further advance the security of the Ledger Blue:
Device application verification: The behaviour of installed device apps is more thoroughly verified in this firmware version. Moreover, custom certificate authority management has been restricted to recovery mode to enhance third party app security.
Hidden accounts: We have implemented the passphrase feature, also known from the Ledger Nano S. Users can now maintain one main account and multiple passphrase-dependent, hidden accounts on the same device. This enables them to appeal to plausible deniability in the event of physical threat.
BOLOS improvements: We have continued to enhance the structure of our operating system, BOLOS. Some refactoring has been performed to improve the SDK and security.
