Application development is an integral part of modern IT processes. Today, it is obvious that IT specialists have a choice: which applications are better to give preference to – traditional or decentralized. Taking into account the fact that the blockchain ideology is becoming increasingly widespread in the world, the development of decentralized applications (DApps) is becoming the most in-demand competency.
However, not all companies have such competence. So to satisfy requests for the development of DApps, as well as to provide other various options for advisory support, https://dysnix.com/blockchain-app-development-service is certainly relevant.
Web applications and DApps
Among people who are not directly involved in IT development, there is an opinion that decentralized applications are a completely new type of development that needs to be learned almost from scratch. To agree with or refute this statement, let’s compare the architecture of web applications that are already familiar to us and innovative DApps. So, traditional web applications or, in other words, traditional centralized information services imply the presence of a server (group of servers) with certain tasks. They are responsible for user authentication, storing credentials and the logic for working with them, storing static files and communicating with each other. The user is provided with a “UI” interface through which the user interacts with the service.
Fully decentralized applications appeared thanks to smart contracts based on the Ethereum platform. The DApps model also implies the presence of a user interface, but its difference from the Web 2.0 application model is that here users are responsible for storing their account data. In practice, this is expressed in the presence of each user’s own private key, which is known only to him alone, and with the help of this key every transaction is signed. In addition to the private key, there is also a public key, which can be freely distributed among network participants. Using these two keys, the user has the opportunity to interact with the blockchain, as well as with smart contracts that are deployed in this blockchain and encapsulate the logic for working with data. The swarm protocol is used to store static data on Ethereum DApps, and the whisper protocol is used to communicate between services. So, we see that the architecture of traditional applications and the architecture of DApps have significant differences.
Requirements for blockchain developers
In the modern crypto world, developers are the key employees of any crypto project, so the demand for them is very high. There are many technologies that are used by developers to write DApps. Here are just a few of them: the Solidity programming language, a remix for developing smart contracts, IPFS distributed file storage, an extension for the Chrome browser, Metamask for interacting with Ethereum, various libraries, etc.
In order to become a sought-after specialist in the development of DApps, an applicant must has both basic and additional knowledge. Basic competence should be knowledge of the basics of programming, especially for beginners in this field. This means that the developer must know at least one of the main programming languages, for example, Python, Java Script or D++. Further to this basic knowledge it should be added the ability of the developer to deeply understand the essence of blockchain technology, namely how blockchain networks, cryptography, algorithms, consensuses and smart contracts work. Since there are programming languages that are designed specifically for blockchain, such as Solidity for Ethereum, mastering such languages is a serious competitive advantage for the developer. To practically consolidate his knowledge, the developer must demonstrate the ability to create some of his own projects or the result of his participation in the development team of another project. In addition, a good potential for each developer is his membership in any thematic community of blockchain developers. Another advantage of a development specialist is his desire to constantly be aware of new trends and study them, since blockchain is a mobile, constantly evolving technology.
All of the above fall under the category of technical knowledge and skills. Of course, this is the basis for the competence of a blockchain developer, but this alone is still not enough. An equally important component is the specialist’s ability to work in a team and be flexible to changing situations. A propensity for analytical thinking, the ability to see the roots of problems and find effective solutions to eliminate them, is also welcome. Recently, serious emphasis has been placed on the ability of specialists to have risk-oriented thinking in order to be ready to cope with the turbulence of the external and internal environment.
Based on all of the above, we can conclude that to develop DApps, knowledge from scratch is necessary only for those who have never worked in web development before. If a specialist already has experience in developing web applications, then after studying the additional features of blockchain technology, decentralized applications can be developed by both front-end and back-end developers.
