Web3 refers to the third generation of the Internet and is the next evolutionary stage of connecting the world. Through blockchain technology, it will subvert the traditional Internet model and create a safer, more private, and more data-driven approach. It is also called the Semantic Web, which allows interactions between users and services to be carried out without the approval of centralized authorities in an open source state.
And what specific steps are required to become the most core role in the Web3 world - a developer?
Growing Demand for Web3 Developers
What is a Web3 Developer?
Web3 developers are software developers who specialize in building decentralized applications using the latest technologies and need to have a deep understanding of blockchain technology, decentralization, and cryptography. In addition, they need to have experience in object-oriented programming, software development, and agile methodologies. Web3 developers use various tools such as Solidity, Web3.js, and Truffle to build projects, such as:
NFT: NFT is a non-fungible token stored on the blockchain that is unique.
DeFi: Decentralized Finance allows the use of financial services beyond the limitations of the current centralized banking infrastructure. Decentralized blockchain technology is the foundation of DeFi.
Crypto: Crypto is a new type of currency that is different from cash in the traditional world. The typical example of cryptocurrency is Bitcoin.
DApps: Decentralized applications are built on top of blockchain and use smart contracts for service delivery. They also work on developing new blockchain platforms and integrating existing systems with blockchain technology.
Is there demand from Web3 developers?
With the rapid growth of the digital age, the demand for Web3 developers is increasing, with the industry growing rapidly by 395% in a single year. More and more companies are looking to integrate blockchain technology, so the demand is expected to grow further. The rise of the industry has transformed careers and created new opportunities in the field. These developers can work in a variety of roles such as software developers, blockchain architects, consultants, etc. So it is certain that there is a huge demand for Web3 developers, and it keeps growing.
Web3 Developer Salaries
There is a career in Web3 development that promises amazing salaries, global recognition, and lucrative growth opportunities. Web3 developer salaries depend on various factors such as location, experience, and type of organization. According to the latest reports, the average salary for Web3 developers is $120,000 per year. With the growth of Web3 development, salaries will continue to increase.
Web3 Developer Roadmap
The Web3 development space is constantly evolving, and Web3 developers are having the best opportunities right now. In this section, we will discuss the roadmap to becoming a Web3 developer.
1. Knowledge of programming languages
Computer coding is key to developing decentralized applications. Most blockchains require knowledge of a programming language for development. It is important to be proficient in programming languages such as:
Solidity
JavaScript
Python
Rust
GoLang
C++
Java
TinTinLand has launched a series of Rust courses and more Web3 development language courses. Interested developers are welcome to embark on a learning journey together!

2. Understand the concept of blockchain
The first thing to start learning is blockchain technology. Blockchain is a distributed database shared among computer network nodes. It is known for maintaining secure records in the Web3 world. So, first learn:
Introduction to blockchain technology: geeksforgeeks.org/blockchain-technology-introduction/
History of blockchain: geeksforgeeks.org/history-of-blockchain/
Features of blockchain: geeksforgeeks.org/features-of-blockchain/
Blockchain structure: geeksforgeeks.org/blockchain-structure/
Blockchain transaction life cycle: geeksforgeeks.org/blockchain-transaction-life-cycle/
Components of a blockchain network: geeksforgeeks.org/components-of-blockchain-network/
Blockchain protocols and how they work: geeksforgeeks.org/blockchain-protocols-and-their-working/
Top applications of blockchain in the real world: geeksforgeeks.org/top-applications-of-blockchain-in-the-real-world/
3. Ethereum
Ethereum is a decentralized blockchain with smart contract capabilities. Smart contracts help users conduct transactions without the need for a centralized system. Records are securely distributed across the network and cannot be altered. You need to have a solid understanding of the following important concepts:
What is Ethereum: geeksforgeeks.org/what-is-ethereum/
Components of the Ethereum Network: geeksforgeeks.org/components-of-ethereum-network/
What is Ethereum Virtual Machine? geeksforgeeks.org/what-is-ethereum-virtual-machine-and-how-it-works/
Nodes and Clients in Ethereum: geeksforgeeks.org/what-are-nodes-and-clients-in-ethereum/
How to deploy a smart contract on Ethereum: geeksforgeeks.org/how-to-simply-deploy-a-smart-contract-on-ethereum/
What is the Ethereum API: geeksforgeeks.org/how-to-build-a-node-js-api-for-ethereum/
4. Smart contract knowledge
Smart contracts are automated programs that run on a blockchain network, making agreements easier. Smart contracts can be used for transactions, executing legal agreements, and managing financial transactions. These are essentially codes that run and are recorded in the blockchain when certain conditions are met. Smart contracts can help you automate processes by initiating the next action when certain conditions are met. Therefore, it is important to understand smart contracts and their lifecycle, and write smart contracts in Solidity. You can refer to the following topics:
What are smart contracts: geeksforgeeks.org/smart-contracts-in-blockchain/
How to Simply Deploy a Smart Contract on Ethereum: geeksforgeeks.org/how-to-simply-deploy-a-smart-contract-on-ethereum/
5. Learn the Web3 framework
Familiarity with Web3 development frameworks is essential for building decentralized applications. Web 3.0 allows developers to easily create and run applications. You can start learning some common Web3 development frameworks, such as:
Truffle Framework: Truffle is a unified web development framework. It provides the tools needed to develop smart contracts, manage, debug, and easily deploy them. This framework helps developers throughout the project lifecycle. For more details, see Creating dApps with the Truffle Framework.
Hardhat Framework: The main goal of this framework is to provide all resources and tools for third-party developers. It supports Django and Ruby on Rails web development frameworks.
Open Zeppelin SDK: This framework was launched in February 2018. It provides secure tools and infrastructure for smooth development.
Brownie Framework: It is a blockchain framework that helps develop Nash equilibrium. It further allows automated interactions of participants related to the NFT market.

6. Understand cryptography
Another important concept you need to grasp is cryptography. Cryptography is a technique for safe and secure communication in the presence of adversarial behavior. Web3 developers need to understand cryptography, its algorithms, and how these algorithms are developed. Here are some important concepts you need to refer to:
Cryptography and its types
Cryptography in blockchain
Blockchain hash function
Block Hash
Encrypting and decrypting files using OpenSSL
7. Decentralized application development
Now that you have a clear understanding of the basics, it's time to build your first decentralized application. By building this application, you will gain hands-on experience and learn about the best practices of decentralized application development.
8. Stay updated
Now that you have all the skills you need to become a Web3 developer, all you need to do now is stay updated. This field is constantly evolving, so be sure to stay tuned for more industry news and developer education content.
