How Do Mobile Bitcoin Wallets Work? – Blockchain Technology [Part 1]

Known by almost anyone with access to the internet, cryptocurrencies such as Bitcoin are being heralded as the payment medium of the future. It is to take advantage of this that a growing number of online and traditional business are now accepting cryptocurrency payments, which is where Bitcoin Wallets become handy.

“The blockchain allows our smart devices to speak to each other better and faster”

— Melanie Swan, the Founder of the Institute for Blockchain Studies

What is a mobile cryptocurrency wallet and how to get one?

A cryptocurrency wallet is essentially an app that gives you access to your Bitcoin wallet address and therefore to your money. Such a wallet could be obtained by virtually anyone on the Google Play or App Store, to receive and send funds in cryptocurrencies like Bitcoin and Ethereum. If you have trouble choosing a wallet, we can recommend the Blockchain Luxembourg app [download for Android] & [for iOS devices] for its design and simple navigation.

As you might have guessed, Bitcoin wallets place a very high priority on security,  which is why every owner is provided with a private key that is needed to access the Bitcoin wallet and sign every transaction. One can, however, make the process a little simpler by setting up a pin code to authorise transactions. Most of such apps also utilise QR-Code technology to facilitate speedy blockchain transactions instead of having the user provide recipient address and amount manually when sending funds.

The development of mobile apps using blockchain technology however is no easy task as the product needs to be secure and stable. Such development can only be done by highly skilled developers with years of experience under their belt, as they require development that is in line with compliance and industry standards.

In the next part, we will take a look at blockchain- the underlying technology of cryptocurrency wallets and its other applications.

Why testing mobile apps is so important

Mobile App Testing: Why You Should Always Do It

Demand for mobile apps is surging year on year, with 2017 topping a global app download of over 175 billion and consumer spending that exceeded past $86 billion. This offers a huge opportunity, with many players attempting to outshine their rivals to increase their share in this space.

Smartphones today are considered very personal devices, with users expecting instant gratification and high performance from the apps they use. The haphazard release of apps, however, is not the solution, with many developers preferring to follow an agile approach to development, supported by a robust testing plan, to ensure the end product is of high quality.

Users also tend to associate their experience of an app with the brand it represents. All apps that carry a brands name should, therefore, be tested rigorously to ensure it functions as it should, in order to prevent any harm to the brand it represents.

Another important reason why app developers should test their apps is compatibility, as there is a vast array of mobile devices in the market, with the number expected to increase to 6 billion by 2020. App makers should, therefore, undertake rigorous test standards to ensure compatibility with the numerous devices and operating systems that exist.

This might not be as big a problem for apps that run on iOS, as Android whose source code is open and shared widely with many OEMs.

An interesting example for this is Facebook, who continue to rigorously test new versions of its products such as Facebook, Messenger and Instagram on over 2,000 devices.


The smooth functioning of an app plays a key role in its success, which is why we at Mood Up base our development and testing on Agile processes. Rigorous test standards play an essential role in ensuring the speed, privacy, security and UX, users expect of an app developed today and should be made a priority. Remember, there is no lack of great apps that failed due to substandard testing!

Why planning is so important

Why Is Planning so Important in App Development?

With over 7 years of experience in working with clients, we can safely say that no two clients are alike. Each client is unique, with some coming to us with a clear vision of the product, while some require our help in narrowing their ideas down to a product.  It’s as challenging as it sounds, but not impossible as we at Mood Up place a core focus on planning.
