The profession of blockchain developer: Trends and prospects – Bits Media

Blockchain projects look pretty attractive, If we study the level of payment of specialists on vacancies sites like hh.ru or job.ru. The highest paid - developers of the highest stage (Senior).

What you need to know and take into account the blockchain developer, how to create unique circuits and applications using smart contracts, What programming languages ​​may be needed - tips give a member of the jury of the Cryptoexperts contest, Member of the Russian Association of Cryptia and Blockchain (RAKIB) Alexander Ryemsky.

Vacancies by Blockchain Developer 

You can choose a remote option, Employment to a foreign company or relocate abroad. The level of payment varies not only depending on practical experience, but also from the use of a certain programming language. Sample plugs of salary offers:

It is important to understand the specifics of the profession. The activities of developers are divided into three main directions:

• Development of existing networks. It is necessary to study the programming language and specific source code. It is also important to evaluate, What area requires improvement.

• Writing a unique blockchain. You need a deep understanding of the main active chains and their shortcomings. Usually, requires great experience in cryptocurrence.

• Creating smart contracts. Implementation of protocols, applications, Conducting a program code audit. Beginner blockchain-deelopers are often sent to this industry.

Nonetheless, It is impossible to get into the Web3 sphere from full zero. First you need to prepare the base. Due to the youth of the industry and the legal status of cryptocurrencies indefinite in Russia, the educational environment does not have specialized educational institutions. However, with a great desire, it is possible to acquire the necessary knowledge and gain practical experience.

Fundamental knowledge

At the initial stage, it will be necessary to study the basics of layout and stylization - HTML and CSS. This block is available in open and free sources online. Will take up to about one month. After you can start a full -fledged programming language - JavaScript. The process is long and laborious, Therefore, it is recommended to take it systematically as part of a special course - for example, Based on additional training from universities or training schools.

Python language is also suitable for Web3-deelopers. However, the bulk of the documentation in repositories is nevertheless written using JavaScript.

It will also be necessary to try work with libraries and superstructures in this language. Then you need to study the Node.js environment at the introductory level - installing packages and launching nodes. It is important to pay attention to the features of Typescript, which also applies to js.

At the final stage, it is recommended to study frameworks. In total, the development of the base takes from six months to a year.

Information is also provided as part of educational institutions of the highest stage according to the specializations of the department "Programming". This volume of fundamental knowledge without practical experience is enough for the work of Junior-Developer in the IT industry. Also, from this step, you can start studying the basics of Web3.

What do blockchain developers do

First of all, It will be necessary to choose the direction - the development of existing networks, creation of new blockchains or implementation of applications using smart contracts. This affects the next block of necessary knowledge.

Creating blockchain

Working with existing networks, especially when implementing a unique idea, requires specific knowledge of classical cryptography. It is difficult to find training materials in this area in the public domain, However, it is still possible.

They are also taught in highly specialized directions - "cryptographer", «Crypitting Engineer», "Cryptation theory".

Additionally, you need to learn the classic programming language. for instance, Bitcoin and Tezos will need C ++. But Stellar needs a special language, created by the developers of this particular blockchain. Also found Rust, Go, derivatives from them and others. It is equally important to monitor the trends in the industry, work of colleagues and innovative solutions.

Creating smart contracts

To some extent, training in this area is easier and takes a little time-less than a month. Ethereum is considered the most common network. Popularity led to that, that in repositories you can find projects of various complexity and try to create your own on their basis. Or just repeat.

Ethereum smart contracts are written in individual Solidity. Gevin Wood participated in his development, which then disconnected from Core Team for the launch of the Polkadot project.

To create ordinary Web3 applications, there are sufficiently fundamental knowledge and Solidity, which the, According to developers, It is considered a very simple language, Similar to js and python.

In the development of protocols of decentralized finance (DeFi) There is another specific need - understanding the basics of financial and exchange operations. This is necessary for their transfer from traditional trading platforms to the blockchain environment using scripts in the programming language. However, the popularity of the etherium led to that, that most of the available options are already adapted in the chain.

Scheme of the smart contract.

Therefore, one of the exits - you can very deeply study the theory of trading. An alternative option is to choose a less popular or derivative blockchain with smart contracts, eg Polygon, Arbitrum or others.

In some cases, this may require learning a new programming language. All beginner Web3 specialists in the field of work with protocols or applications need to master additional resources:

• Web3 library with orientations on the studied programming language;

• Tools - Geth, Remix, Truffle, Metamask;

• Openzeppelin-a resource with a selection of ready-made smart contracts.

Conclusions

Experts joke, that the creation of Defi protocol on a smart contract is easier, than any front-end development of the site with integrated animation. Nevertheless, training at the fundamental stage will take up to one year. The same amount of time will be spent on developing tools for Web3.
