Today, only the lazy do not talk about cryptocurrency, about its advantages and prospects; some even know that cryptocurrency was created based on blockchain technology. And only a few will tell you that cryptocurrency is not a part of the blockchain, but is just an object of application of this technology. The blockchain itself is based on a certain philosophical idea – the absolute impossibility of hiding any changes in a specific storage of data or assets created for some purpose. At its core, blockchain is a set of different technologies and languages that are used in a specific interaction to ensure decentralization of actions on the network.
In addition to interest in blockchain, interest in the development of decentralized applications (DApps) has also grown sharply. DApps have a number of advantages and the main ones are accessibility, security, cost-effectiveness, reliability and trust. We can conclude that working with decentralized applications brings real benefits and, at the same time, the lack of in-house capabilities and experience in developing DApps can be easily compensated by collaboration with https://dysnix.com/blockchain-app-development-service.
Knowledge and experience
In the wake of growing demand for blockchain technology, the number of people, including developers of traditional web applications, who want to explore the basics of blockchain is steadily growing. And, of course, applying for a relevant job they must meet a certain level of competence. First of all, developers must know and understand the essence of blockchain technology and navigate a fairly large amount of its terminology. To expand their knowledge in this area, they can, for example, use the Ethereum documentation, which is as informative and easy to understand as possible.
We can often hear the opinion that the main thing a developer should know is the Solidity language. However, many experts believe that only knowledge of Solidity without proper experience in using it in writing smart contracts can lead to significant waste of resources. In many cases knowing Solidity is not enough. Let`s remember the Solana blockchain protocol which has been actively positioning itself in the blockchain network market. Solana is a platform that creates DApps and smart contracts, which are called the “Solana program” in this blockchain. Along with the Proof of Stake consensus, Solana increases the speed of its transactions due to the Proof of History algorithm, and uses the Rust programming language to write smart contracts. Unlike the Python language, which is an interpreted language, Rust is a compiled language and, of course, it is advisable for developers who want to work with blockchain to learn it.
Certainly the main programming language used in blockchain development is Solidity. As for the Python language, it is inferior to Solidity in terms its demand for blockchain, although, of course, specialists with knowledge of Python can also participate in blockchain projects. The truth is that the movement towards blockchain is accelerating significantly, covering more and more new areas of human activity, which means that the market for blockchain developers is now in dire need of specialists, especially specialists with Senior or Lead status. Above, we said that it is not enough to write an ideal smart contract simply by knowing the Solidity language; you need to know and be able to apply in development a large number of various nuances that are acquired along with practical experience in blockchain development.
Strength and weakness
The web developer market is quite extensive, and accordingly, its data stores contain a huge amount of information about specialists of different levels of knowledge and experience. Those who want to hire the right developer often find it difficult to sort through this array of offers. In such cases, so-called personal portfolio sites, which allow a programmer to personalize both himself and his level of competence and experience, look much more advantageous in such cases. When creating their portfolio websites, many programmers strive to take into account the latest and most current trends in website design, use all sorts of “tricks” in the form of animation, make interactive links to various sources of information and strive to reflect their personal “modus operandi” as fully as possible. Strictly speaking, the presence or absence of a developer’s own personal website does not at all indicate how good and professional this developer is. In order to assess the level of competence of a specialist, there are many relevant test projects, and many employers use them successfully. However, having his own portfolio website still allows the developer to express himself more clearly and unconventionally against the background of his competitors and to interest this or that company.
As strange as it may sound, there is often a fear of programming itself among developers, even those who are not new in this area. The reasons for this fear lie in the fact that the programmer is simply afraid of harming the development that was already created before him. Such fears are justified in cases where there is interference in the production database, then there is a risk of violation of confidentiality, loss of some information or assets, etc. However, more often than not, each developer works locally, and any change he may make only affects the code that is running on his computer. However, such fear slows down the work of not only beginners, but sometimes even experienced specialists.
