Introduction

Ledger Nano S is one of the most prominent hardware devices available in the market. Before diving into nitty-gritty of Nano S, let us have a quick flashback on hardware wallets. Since coins are stored offline with this method, they are recognized as a secure means of storing bitcoin and altcoins. Hardware Wallets provide a protected infrastructure so as to run safely even on a malware infected computer.

Hardware wallets are precisely the solution for this because the private keys of the wallet are stored on the physical device rather than any software on the computer system. Also, today, most of the hardware wallet devices are equipped with a screen which adds an extra layer of security while making a transaction. We will also discuss other advantages of a screen display at a later stage in this article. However, you can read more about cryptocurrency wallets, in more detail as well

At first glance, Ledger Nano S looks like a pen drive. The only difference is that it has to be connected to a USB cable for usage.

Ledger - The Company

Ledger develops products and applications to safeguard cryptocurrencies and blockchain.  The company currently has its headquarters in Paris, Vierzon and San Francisco and was founded back in 2014. Since then, Ledger has become a popular name in cryptocurrency security market and is now one of the fewer and best wallet providers around the globe. While they have developed custom OS called BOLOS for this purpose, Ledger currently has two distinct wallets under its belt: Ledger Nano S and Bluetooth-enabled Ledger Blue. Presently, they have clients in 165 countries and have sold over 1M ledger wallets.

Device Appearance

Ledger Nano S comes with a metal covering which can withstand nominal damage. The device design is compact and small which makes it easy to carry in a pocket.

It comes with two buttons and a screen to control the transactions. Buttons are usually used to input PIN and confirm payments. To approve the transaction, both the buttons are to be pressed simultaneously which adds an extra layer of security as most of the time, you wouldn't push both the buttons my mistake.

Ledger Nano S Compatibility

Ledger Nano is compatible with following:

• OS: Windows 7-10, Mac 10.8 +, Linux and Chrome OS.

• Software Wallets: Mycelium, Electrum, MyEtherWallet, Copay, BitGo, GreenBits,   Ledger Wallet Bitcoin, Ledger Wallet Ripple, Ledger Wallet Ethereum.

Why is Ledger Nano S Secure?

Tamper-Proof Seal

Initially, the device package used to arrive with an anti-tampering seal. The tap on the box was regarded as an assurance that no mediator had tampered with the device while it was shipped.

But, as of now the company is using a cryptographic mechanism to verify the integrity of the device. The box also has a card mentioning it:

Physical Buttons

The device has two physical buttons whose one of the task is to explicitly confirm the ongoing transactions. Thus, even if an intruder gets hold of your wallet seeds and other details, he may not be able to hack the wallet since he doesn’t have access to the actual device.

PIN Code

As a part of Ledger Nano S setup, you are prompted to set a 4 digit pin code for security purpose. This is particularly useful in case you lose the hardware device. While a stranger may get a hold of your device, he cannot operate or make any transactions without the PIN. Also, the device wipes all the data automatically after three consecutive incorrect PIN inputs.

Offline Storage and Backup

Well, since it’s a hardware wallet - you already know this. However, Nano S  helps you create a backup by providing 24-word  seed phrase. The seed phrase can be useful to reset and restore the damages or loses.

Make sure to note those phrases ONLY on paper and not on your computer as it eliminates the whole point of offline storage and security. Anyone can attack your computer, and if someone has access to the system, they can always get access to the seed phrase as well.

Supported Currencies

Ledger Nano S supports most of the legit cryptocurrencies like Bitcoin, Ripple, Litecoin, Ethereum, etc. The best part is it also supports the famous ERC20 Tokens and the list keeps updating. You can check the whole list of supported coins here.

Ledger Nano S Price

Ledger Nano S is the cheapest among it other peers like Trezor and Keepkey. It can be purchased for 79€ (excluding tax) from their official site with free shipping.

Where Can I Buy Ledger Nano S?

While we would suggest you to buy the device from their official website. However, make sure NEVER to purchase hardware wallets from eBay as they have been reports of hacks previously.

Why is Screen Important in Hardware Wallets like Ledger Nano S?

The screen in any hardware wallet is pretty much essential and performs the same function - it secures the transactions.

However, the wallet screen also generates a 24-word recovery phrase (or seed) which is evitable for backup and restore capabilities. You may have a mobile wallet in your phone which can only be secure if you're using single-handedly and is never connected to the internet. This is the case because, in mobile wallets, the recovery phrase is displayed on the mobile screen and phones are always prone to data leaks.

This is how the hardware wallets come into picture - they provide security as they are not connected to the internet. They generate and store the recovery phrase offline and can be accessed only with the wallet screen.

The Ledger Nano screen also helps in confirming the payments by prompting the amount and address.

How to Setup Ledger Nano S Hardware Wallet?

Let us now get to the most interesting part - installing and configuring the Ledger Nano S.

A quick suggestion though, download and install ledger application from here in the computer system you intend to use to access the hardware on future. And follow the steps given below:

• Connect the hardware wallet to the computer system with USB cable available within the box. You'll see the wallet come to life with a welcome screen.

• You'll prompted with numerous options like: Configure as new device or Restore configuration (Use buttons to check options). Choose "Configure as new device?" since we're setting up the device for the first time. To choose, press both the buttons simultaneously.

• Next, press both the buttons simultaneously to  add a PIN Code. To change the digit press left-right buttons. You can either have a four-digit (v1.1-1.2) or an eight-digit (1.3+) digits PIN code, based on the firmware of the Ledger Nano S. Make sure to memorize it as it will be used to operate the device and confirm transactions in future.

• You'll then be asked to confirm the PIN code. Press both the buttons together and input the PIN.

• The wallet will then begin prompting word-phrases. Jot them down in the "Recovery Sheet" available with the box in the same order as prompted. To see the next phrase, press right button.  You can also create a copy of recovery sheet and store it at a safe location. Once you have scribbled all the 24 words, press both the buttons together.

• Like PIN, you'll be asked to confirm pass-phrase as well. But this time, you'll be asked to select a mapped word for a random number.

That's it for configuring the Ledger Nano S device. Let us now see how to install application in the computer system to interact with the device.
