    Web 3.0 is more than simply a new technical trend; it is evolving into a revolutionary worldview. The third generation of the internet is largely concerned with restoring consumers' control and ownership of their data.

    Any ambitious tech worker who is familiar with  web3 may want to become a web3 developer and join the game-changing sector. Many of you have probably fantasized about the monetary benefits of working in the field of web3. Because of the scarcity of web3 developers, salaries for web3 specialists have skyrocketed.

    Answering the question as a newbie is tough since you lack knowledge and practical experience with web3. The conversation that follows serves as a web3 developer roadmap, including a summary of why you should pursue the profession of web3 developer. You can get a good idea of the talents needed to cater to the obligations of web3 developers.

    Before we get into details, let's see who is a web3 developer.

    Who is a Web3 Developer?

    As the name implies, a Web3 developer is someone who produces blockchain-based solutions. This person is seeking to establish a decentralized society, which is not for the faint of heart. A Web3 developer typically has a strong background in mathematics and computer science.

    To be considered, you must have prior knowledge of blockchain technology. But that's not all: you'll also need strong problem-solving talents, as well as creativity and communication skills. But what is a blockchain?

    Short Note: A blockchain is an unchangeable, public, and decentralized database that people own. Because the data is stored in the form of blocks, the term "blockchain" was coined. Each block has its own data, hash, and the hash of the previous block to connect them.

    Roles and Responsibility of a Web3 Dev

    The first step in developing your knowledge of web3 development is to describe web3 developer duties. When you know what you need to do as a web3 developer, you can determine the talents you'll need to study. Interestingly, web3 developers' responsibilities differ depending on the specialty, such as play-to-earn games, DeFi, metaverse, NFTs, or other blockchain applications. However, web3 developers' primary tasks would be core development and application development. The following is an outline of the tasks you must complete in each role.

    Web3 Core Developer

    The web3 core developer is in charge of blockchain system design, architecture, and security. If you wish to work as a core developer for web3, you must be prepared for the following responsibilities.

    • From the ground up, designing and constructing layer 1 blockchain networks.
    • Security patterns and consensus techniques for application networks are being tailored.
    • The creation of network architecture and operational nodes.
    • The entire network is being monitored.
    • A web3 core developer's work provides a credible framework for defining the future of decentralized apps (dApps).

    Dapps: DApps, or Decentralized Applications, are blockchain-based applications.

    Web3 Application Developer

    Web3 application developers use the infrastructure provided by core developers to construct and deploy dApps. Front-end development and back-end development are two distinct components of web3 application developers' duties.

    Web3 Backend

    Web3 backend development differs from traditional backend programming in that no servers are required. Developers can leverage layer 1 network technologies that are appropriate for the dApp's aims and develop smart contracts to define the application logic and automation. Backend duties in web3 development primarily entail building and deploying smart contracts or working with distributed databases.

    Web3 Frontend

    The front end of a web3 application is the client-side element of the application. A significant portion of the work on front-end architecture is devoted to enabling seamless interaction with smart contracts. Front-end development also focuses on developing appropriate systems to ensure user identification and wallet connectivity.

    How to Become a Web3 Developer?

    The preview of job prospects for web3 developers, as well as the specifics of web3 developer tasks, set the ideal tone for any novice looking for the greatest web3 careers. For newcomers, the obvious question of "What do I need to become a web3 developer?" would be a top concern.

    Learn the Basics of Blockchain

    The first notion you must understand to become a Web3 developer is blockchain. This allows you to quickly build and optimize smart contracts.

    A blockchain is a database that is user-owned, unchangeable, public, and decentralized. The data is organized into chunks (therefore the term "Blockchain") To connect the blocks, each block carries its contents, hash, and the hash of the previous block.

    The hash is a unique string created from the data. Depending on the information, the hash varies. This could have occurred during the deployment of JWT credentials in NodeJS.

    Decentralized Application

    DApps, or Decentralized Applications, are blockchain-based applications. The following technologies are commonly used in DApps:

    • Frontend frameworks such as React, Vue, and Angular.

    • Backend frameworks include Rust and Solana, as well as Solidity and Ethereum.

    Frontend Development

    If you wish to work as a web3 developer, you should have some experience in frontend web development. Blockchain technology could underpin the backend architecture of Web3 apps or dApps, with JavaScript in charge of the front end. As a result, you must be proficient in the following areas:

    • Common HTML tags.

    • CSS fundamentals and features such as Grid and Flex.

    • Tailwind, Bootstrap, Semantic UI, and other CSS frameworks.

    • Variables, functions, ES6, classes, and other JavaScript concepts.

    • JavaScript frameworks such as Angular, React, and Vue.

    • Furthermore, aspiring web3 developers must have a strong understanding of the principles and technology related with web2 backend.

    Basics of Ethereum

    Ethereum is a blockchain that is used to execute smart contracts. In 2022, Ethereum will be by far the most popular blockchain for establishing smart contracts. Solidity is the language used to create smart contracts. The official documentation is an excellent starting point for learning more about Ethereum.

    Basics of Smart Contracts

    Smart contracts are contracts that are executed by immutable code on the blockchain. Smart contracts are comparable to JavaScript classes. DApps are powered by these.

    Understanding the concept of smart contracts isn't enough; you also need to be able to create them. This is where Solidity comes into play. Solidity is a high-level, object-oriented programming language designed exclusively for creating smart contracts.


    The final outtake from the guide to becoming a web3 developer suggests that you have to learn many skills to achieve the goal. Web3 applications or dApps would define the future of technology and digital solutions in general. Therefore, beginners must search for the right direction and resources to earn the title of web3 developer. 

    Over the course of years, web3 has transformed into an inherent philosophy emphasizing the decentralization of the internet. Many promising technologies such as blockchain, NFTs, DeFi, metaverse, and NFTs come under the umbrella of web3. Aspiring candidates can explore many prominent value advantages in their journey toward the role of web3 developer.

    Web3 FAQs

    What programming language is used for Web3?

    Solidity was the first smart contract programming language and is now the most popular on Web3.

    Are Web3 developers in demand?

    Web3 software engineers are in high demand by firms looking to create their own blockchain or decentralized apps, which necessitates knowledge of numerous programming languages such as Python, Java, Solidity, and others.

    Is Web3 easy to learn?

    Web3 combines the best of both worlds, according to Chris Dixon of venture capital firm a16z: the decentralized ethos of Web1 and the engagement of Web2. While Web3 is gaining popularity among computer enthusiasts, entrepreneurs, governments, and large IT corporations, it is not an easy idea to grasp.
