We continue to deal with various wallets for cryptocurrency. Last time I did a bit of digging in software wallets, and today I’ll tell you a little about the hardware. At the beginning a small reminder.

Under the wallets in cryptocurrencies understand at the same time:

  • set of keys for access to money;
  • programs that manage these keys and allow you to conduct transactions on the crypto currency network.

In order not to be confused when we talk about the key set, I will use the term “private key”. Although we all understand that in the key pair there is also an open pair, and also that the pairs themselves can be several.

We will talk about the wallet exactly as a means of managing, storing and conducting transactions. Without a wallet, you cannot receive, save or spend your bitcoins or funds in another cryptocurrency. The wallet is your personal interface to a cryptocurrency network, similar to a bank account for a currency.

So, hardware wallets. Let’s start with the definition. Hardware wallets are physical devices designed to safely store cryptocurrency. Some software and online-wallets support the storage of funds on hardware wallets.

Before we start comparing specific models of hardware wallets, let’s see what most of these wallets are able to do, and we will dwell in detail on the features of each of them.

Let’s talk a little about wallets in cryptocurrencies. By “cryptocurrency”, I, in the first place, will have in mind Bitcoin. In other cryptocurrencies the situation is similar and if you are interested in details, you can check this out yourself.

Despite the ongoing hype around cryptocurrency and blockchain as technology, in my opinion, very few people are talking about the security of these solutions. Everyone is concentrating on the various advantages that blockchain technology provides, discussing the mining and jumping courses of cryptocurrency, while it is security that is critical, especially when it comes to money or distributed property registries. All information for the article is taken from open sources, such as https://bitcoin.org, https://en.bitcoin.it/wiki, https://bitcointalk.org, https://github.com and others.

Below is a shallow review of the cryptocurrency wallets and their security. The more I immersed myself in this topic while writing the article, the more I was surprised that there are so few hackers and withdrawals from users of the same Bitcoin. But first things first.

The new recycling program from Samsung finds new applications for old technologies. For example, according to the information published by Bitcoin.com, the company came up with a way to create a mining farm based on smartphones from the Galaxy line.


Certainly, when creating a “mobile” farm, some technical specifications for smartphones were improved. However, Samsung claims that eight Galaxy S5 can work with excellent energy efficiency, not yielding to a standard PC.

Such a mining farm was presented during the recent Samsung developer conference held in San Francisco. Creation is the brainchild of Creative Lab from Samsung, the inner center of innovation and development, which is located in Samsung Digital City, in Korea.

In addition to the platform for the production of crypto currency, the recycling program also found out that the old Galaxy tablet can easily turn into a laptop with Ubuntu. The company was also able to use the old Galaxy S3, with face recognition software as the basis for a home security system.
