Ledger Blue is the most advanced hardware security gear on the market. It boasts multi application execution, and packs enterprise-level crypto-capabilities into a lightweight handheld device designed and crafted in France. It is architected around a Secure Element, featuring a touchscreen and USB & Bluetooth connectivity.
It is available for the price of 229 EUR (without VAT).
A powerful and flexible device
Blue is the latest generation product from Ledger, the result of more than two years of research and development. This high-end device embeds a large touchscreen to securely manage transactions and complex smart contracts. Its slick yet robust casing encloses the best-in-class technology built upon Blockchain Open Ledger Operating System (BOLOS), a powerful and flexible platform.
Packed with hardware features
The Ledger Blue is based on a dual-chip architecture embedding a ST31 Secure Element and a STM32 microcontroller thus achieving a fully isolated environment. It features a LED-backlit color touchscreen to navigate easily and validate transactions. It is powered by a lipo rechargeable battery and communicates with USB or Bluetooth devices.
Designed for multiple secure apps
Thanks to its modular architecture, the Ledger Blue runs multiple dedicated companion apps in full isolation on top of its firmware. The strong security model allows to add new cryptocurrencies or apps without the risk of compromission of the master seed. Transaction integrity is ensured by the WYSIWYS paradigm (What You See Is What You Sign). The flexibility of the device enables enterprise level usage: with all major crypto libraries embedded in the firmware, any type of blockchain can be supported.
What our technological partners say about the Ledger Blue
Stratumn introduced the concept of “Proof of Process”: a scalable protocol that allows multiple partners to trust a common process, or a workflow, by decoupling the proof of data from the secret data in a way that results in a single contextual proof that spans all the steps of a process.
“At Stratumn, we closely partner with Ledger to secure how customers and partners interact with Proof of Process Technology. Their open source SDK allows our team to build application-specific interfaces, making the experience seamless and complete.” — Richard Caetano, CEO Stratumn
Monax Industries (formely Eris Industries) empowers developers to embrace participatory software architecture via distributed computing and smart contract systems. Monax’s products comprise the first platform that allows the full potential of blockchain based technologies to be realized in enterprise. Monax announced a partnership with Ledger regarding hardware security in 2016.
“When deploying enterprise blockchain applications in production, security of digital assets and cryptographic keys is of paramount importance. The Ledger Blue is a powerful and flexible solution for enterprise grade blockchain applications, ensuring integrity of transactions at the endpoint level.” — Casey Kuhlman, CEO Monax
STMicroelectronics is a world leader in providing semiconductor solutions with one of the industry’s broadest product portfolios, notably in hardware security. Ledger announced its collaboration with STM in March 2015 for the design of the Ledger Blue.
“STMicroelectronics’ microcontroller and radio technologies offer a broad range of advanced features including hardware security, reliable connectivity, and low power consumption, allowing Ledger and other partners to create unique and innovative devices that combine banking-grade security with full system openness” — Marie-France Florentin, General Manager, Secure Microcontroller Division, STMicroelectronics
