Ledger Blue – a Hardware Wallet for the Smart Contract Era

Ledger is a French company known for the set of hardware wallets with Bitcoin. Now it has launched a new extension of the product line - Blue Ledger.

Ledger announced a new purse as the best hardware wallet on the market today. Ledger Blue is very different from the previous Ledger products. This portable touch device has a screen of 320 x 480 pixels (with BlueTooth and NFC), and it can run different applications.

Support for smart contracts

Ledger launched its first product, the Ledger Nano, in December 2014. It was introduced as a small, safe, and inexpensive hardware wallet. The Ledger team of hardware wallet follows the infrastructure development of Bitcoin Diamond (BCD) and can add support for this cryptocurrency created by new hard forks.

Then the Nano S was released. It was the expansion of the line. Nano S had a small led screen and support to other cryptocurrencies such as Ethereum and Litecoin.

The Ledger Blue launch is a response to the increasingly complex needs of an ecosystem that now includes smart contracts, token exchanges, and other trading assets. Now the transactions and contracts can involve multiple parties and variables that each signatory should check.

Ledger Blue allows you to create your app to test specific smart contracts. The amount of screen real estate means that the application may present a few fields of data to check before the final confirmation. It is an important step when the contract will automatically complete itself.

The applications for currency processing work in isolation and cannot access memory or storage used by others. It means cryptographic secrets should remain safe even if one application is compromised.

Support for cryptocurrencies

Hardware wallet also includes support for many cryptocurrencies. Technical specifications of the device are Bitcoin, Ethereum, Zcash, and Dash. There is also the possibility to integrate with other wallet suppliers, such as Electrum and Mycelium.

The Ledger team of hardware wallet follows the infrastructure development of Bitcoin Diamond (BCD) and can add support for this cryptocurrency created by new hard forks.

Now, only a couple of dozen lesser-known exchanges said about the support of Bitcoin Diamond. Major sites such as Bitfinex, Poloniex or Bittrex are not in a hurry to add the new coin.

Recently, the developers' team has reported on adding support cryptocurrency Stellar Lumens (XLM). On the website, the company published installation instructions for the appropriate application of the Ledger hardware wallet. The news had a positive impact on the price of cryptocurrency, which has increased by more than 11% in just one day.

The company added Bitcoin Gold to Ledger Blue. It also plans to add support for Monero and Qtum soon.

Tech targets

Ledger Blue is built on the principles of open source for software and hardware design.

While wholly closed enclosures supply most smart devices, the Ledger Blue housing is held in place magnetically and can be removed.

Some corporate clients have already registered. They include Monax and Stratum - two platforms of the business chains that will use Blue as the end for their services.

Ledger hopes to attract developers to the platform with its corporate SDK included in the product.

The product at a price 229 EUR is high, but it offers an entirely different user interface for everything that is currently on the market.

Ledger Blue is simple, versatile, and is currently one of the easiest-to-use products.
