What are decentralized applications or dApps?
Technology advances every day, new solutions are developed and thousands of mobile applications are downloaded from the stores. Along with all this, the concern for data security and the privacy of user information increases. This is how new technological solutions and tools arise, such as decentralized applications or also called dApps .
In this post we will talk about what decentralized applications or dApps are, their advantages compared to traditional apps and the importance that they may acquire in the not too distant future.
Today we are going to talk about the final purpose of Blockchain development, decentralized applications .
Surely if you are interested in Blockchain development , you have already heard about them. But if you haven’t, don’t worry, because today we are going to talk about them in depth and we are going to tell you everything you need to know about decentralized applications.
Traditional vs decentralized applications
As in all areas of software development, developing an application, whether mobile or web, is made up of two different areas: Backend development, and Frontend development. Backend development is also known as “server-side development” and within it the software that is responsible for managing and processing data within an application is created. This is where all the application logic is developed.
This part is super important, but it has a problem and that is that the user cannot interact with it, so it is necessary to complement it with frontend development .
In this part of the development, the web interface is created so that users can easily interact with all the internal logic of the application.These two differentiated areas that are essential within the development of an application are really the same whether we are talking about traditional applications or decentralized applications. Decentralized applications are the future of iot.The difference between them lies mainly in two aspects: the technologies that are used, especially in the Backend part, and above all and almost more importantly, the type of server with which we interact in each case.
Surely if I ask you 5 examples of traditional applications right now , you would tell me without hesitation and very quickly: Instagram, TikTok, Facebook, Twitter and Wallapop.
If we talk about the languages that have been used in these applications to develop the backend part, languages that surely sound familiar to you come to mind, such as Python, Java, PHP or C.
When we, as users, interact with these applications, what we are doing is interacting with the servers that are owned by the companies that have developed and manage these applications. So we could say that these servers are centralized, because they depend on a central agent, which in this case is the company that owns them.
If we switch third and go back to decentralized applications, we have something quite different.In this case, the backend of these applications is developed in the form of intelligent contracts or smart contracts, so the languages that we are going to have mainly are somewhat different from the ones that I have mentioned before. In this case, languages such as Solidity and Rust prevail. From here then, it directly follows that in this case what we are going to have are Applications that work on blockchain technology, and this is great because these applications then are going to offer us all the brutal characteristics that this technology has.
And one of these characteristics is the one that mainly differentiates these applications from the traditional ones, because in this case we are not going to have a central server with which the users are directly interacting when they use the App, but rather they are going to interact with the App itself. Blockchain.
Advantages of Decentralized Applications (DApps)
Decentralized Applications offer a great advance and completely change the current application landscape, because you will no longer need to hand over all your data to a company like Meta. The Blockchain allows you to be the owner of all your data.
This is amazing, right? Finally, users are going to have something relevant in the new Internet, and we are going to be the owners of all our information.And not only this, because decentralized applications are open source, or open source. This means that anyone, at any time, can consult all the code of the decentralized applications that he is using. This adds a truly important value and distinguishes blockchain development from traditional development. Because here, two things are gained mainly:
Trust on the part of the users, since they can see at any time what is happening within the application.It speeds up and improves the evolution of these applications, since everyone can access this code, experienced programmers can propose their improvement ideas. And also, being able to access the code is super useful for beginner blockchain developers, because it’s super nutritious to see how the top developers in this sector program.
As you can see, decentralized applications offer very important advantages over traditional applications. And precisely for this reason they are the cornerstone and the final purpose of blockchain development. These applications are going to change the entire landscape in a few years, and for this to be possible, more blockchain developers with sufficient knowledge to develop these applications need to enter the market.
How to be part of this great job opportunity?
As you can see, the innovation of the entire Web3 and Blockchain ecosystem does not stop growing and evolving every day. More and more platforms are joining the use of blockchain technology to increase the efficiency and security of their processes and this really benefits us all.
That is why this training is suitable for all audiences, whether you are a technical person or not.In addition, not only will you leave the master’s degree being a Back-end developer, but we are also going to teach you how to program in Front-end so that you can be an all-terrain developer, a Full-Stack developer.
