Power & Flexibility
The Ledger Blue cryptocurrency hardware wallet is the latest generation product from Ledger, the result of more than two years of intensive research & active development. The Ledger Blue Hardware wallet (now in South Africa) boasts a large touchscreen making transactions easier, more comfortable to manage your crypto transactions & complex smart contracts. Built into a very modern design casing offering both style & protection for your Ledger Blue Wallet. You can rest assured that your Ledger Blue hardware wallet contains the best-in-class technology stacked on top of the Blockchain Open Ledger (BOLOS) platform, an operating system that is both powerful & highly flexible.
The Ledger Blue hardware wallet is the most advanced cryptocurrency hardware security gear currently on the market. It boasts multi-application execution and is packed with enterprise-level crypto-capabilities into a lightweight handheld device designed and crafted in France. It is architected around a Secure Element, featuring a touchscreen, USB & Bluetooth connectivity.
The Ledger Blue is based on a dual-chip architecture, embedding an ST31 Secure Element & an STM32 microcontroller. Thus achieving a fully isolated environment. It features a LED-backlit colour touchscreen to navigate easily & validate transactions quicker. Powered by a high-quality LiPo (Lithium Polymer) rechargeable battery, you are sure to get the most time with your Ledger Blue. Your Ledger Blue also communicates with most USB & Bluetooth devices.
With the Ledger Blue, you are making use of some of the more popular standards compliance options available today. This means that the amount of other devices that you can link to becomes more!
Multiple Secure Apps
The Ledger Blue hardware wallet can run multiple dedicated companion apps, fully isolated on its firmware, thanks to its modular architecture. You never risk compromising the master seeds when adding new Cryptocurrencies or apps. This is because of strong security models that have been built into the Ledger Blue Cryptocurrency hardware wallet, making your wallet safer.
The WYSIWYS (What You See Is What You Sign) paradigm ensures the transaction integrity on the Ledger Blue. The Ledger Blue offers flexibility at an enterprise-level. The firmware embeds all the major cryptocurrency libraries, any blockchain type can be supported. This is what the Ledger technological partners say about the Ledger Blue hardware wallet.
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 step of a process.
