Responsibilities of Web3 Developers

The foremost thing required in building your expertise for web3 development is an outline of web3 developer responsibilities. When you know what you have to do as a web3 developer, you can identify the skills you have to learn for the same. Interestingly, the responsibilities of web3 developers vary according to the niche, such as play-to-earn games, DeFi, metaverse, NFTs, or other blockchain applications. However, the common responsibilities of web3 developers would focus on core development and application development. Here is an outline of the tasks you have to deal with in each role.

Web3 Core Developer

The web3 core developer takes care of designing, architecture, and security for blockchain systems. If you want to become web3 developer as a core developer, you have to prepare for the following responsibilities.

  • Designing and developing layer 1 blockchain networks from the foundation
  • Tailoring security patterns and consensus protocols for application network

Web3 Application Developers

The web3 application developers leverage the architecture offered by the core developers for designing and deploying dApps. You can find two distinct aspects in the responsibilities of web3 application developers, such as front-end development and backend development. What are your responsibilities as a web3 developer in both cases?

  • Web3 Backend Development

Web3 backend development is completely different from the usual backend programming as you don’t need servers. Developers can use layer 1 network solutions suited to the goals of the dApp and create smart contracts for defining the application logic and automation. The primary tasks in the backend side of web3 development involve designing and deploying smart contracts or working with distributed databases. 

  • Web3 Front-End Development

The front-end serves as the face of web3 applications, the client-side aspect of an application. A major share of the work on front-end architecture focuses on ensuring seamless interaction with smart contracts. Front-end development also focuses on establishing suitable mechanisms for ensuring user authentication and wallet connections.

What Do You Need to Become a Web3 Developer?

The glimpse of career opportunities for web3 developers alongside the details of the responsibilities of web3 developers set the right tone for any beginner to seek the best web3 careers. The obvious question of “What do I need to become a web3 developer?” would be an important priority for beginners.

Without wasting any time, you must dive into an outline of the essential skills for web3 developers, such as the following –

Become Web3 Developer

Start with Blockchain Basics

The obvious entry in the list of web3 developer skills, blockchain technology, is the foundation of a new web3 domain. Blockchain is the immutable, decentralized, and public database under the ownership of users. The database stores data in the form of consecutive blocks associated with each other with hashing algorithms. 

Blocks contain the concerned transaction data alongside its own hash, as well as the hash to the previous block. Any changes in the blocks would lead to changes in hash, thereby invalidating the next block. With the copies of blockchain stored across multiple computers worldwide, it is practically impossible to introduce malicious changes in blockchain. A course on blockchain fundamentals could be a great way to start your journey towards becoming a web3 developer.

Fundamentals of Decentralized Applications

The web3 developer roadmap might remain incomplete without references to decentralized applications. dApps created on the top of blockchain networks serve as one of the core elements of the web3 landscape. Every aspiring web3 developer must know about dApps and the technologies associated with them. The notable technologies for frontend development in dApps would include JavaScript frameworks, such as Angular, React, and Vue. 

On the other hand, the backend technologies for dApp development include Rust/Solana or Solidity/Ethereum. Decentralized applications can serve many crucial use cases, and they have been revolutionizing many industries. For example, dApps can help in managing integrity of records alongside facilitating easy and secure payments with cryptocurrencies. In addition, decentralized apps can also contribute significant value improvements in ensuring successful execution of smart contracts. 

Basics of Frontend Web Development

If you want to become web3 developer, then you would need some experience in frontend web development. Web3 apps or dApps could have blockchain technology underlying their backend architecture and JavaScript helming the frontend. Therefore, you need fluency in the following aspects, 

  • Common HTML tags
  • Basic properties of CSS and features such as Grid and Flex
  • CSS frameworks such as Tailwind, Bootstrap, Semantic UI, and others
  • Variables, functions, ES6, classes, and other concepts of JavaScript
  • JavaScript frameworks such as Angular, React, and Vue

In addition, aspiring web3 developers must also have a solid command of the principles and technologies associated with web2 backend.
