Want to learn web3 in 2025 but don’t know where to start? We’ve created this 4-part guide that covers the complete roadmap and syllabus for learning web3. Web3 is a fast-evolving industry that is drastically expanding thanks to a lot of new blockchains, projects, dApps, and technological upgrades that keep getting announced almost every week. This fast pace of the Web3 industry makes it really difficult to get a hold of, especially for a newcomer.
To simplify this learning process, we will give you an overview of the foundational aspects of blockchain, crypto, and web3, what are the use cases of these technologies, how exactly do web3 companies earn money. And don’t worry; we know that at the end of the day, as a developer (or even a beginner), your career is your priority. So we will also explore some career opportunities if you are looking to become a web3 developer by learning Solidity.
Web3 Industry Overview
Web3 is the next step in the evolution of the Internet. To understand “What is Web3?”, we should first learn about the web 1.0 and web 3.0 and see web 3.0 as the next frontier.
Web3 and blockchain technology have garnered significant attention over the past few years. But what exactly are they, and are they worth investing your time in? Let’s break it down.
Layer 0 Protocols
Layer 0 protocols, like Cosmos and Polkadot, allow developers to build their own blockchains, often referred to as Layer 1 blockchains. While these protocols offer great technical capabilities, they are still searching for widespread use cases. The majority of web3 developers work on pre-existing and popular blockchains like Ethereum, Binance Smart Chain, Aptos, etc.
Layer 1 Blockchains (L1)
Layer 1 blockchains are the foundation of Web3. You’ve probably heard of Bitcoin and Ethereum, the two most well-known examples. These blockchains introduced the concept of decentralized money and paved the way for subsequent innovations. Ethereum is like a decentralised open-source computer on which anyone can build dApp for various use cases. Similarly, there are many L1 Blockchains with their own speciality suitable for various use-cases.
Here’s a list of 35 Layer 1 Blockchains to discover more L1 chains and dive deeper.
Layer 2 Blockchain (L2)
Layer 2 solutions, such as Polygon and Arbitrum, are designed to scale Layer 1 blockchains by creating smaller, faster blockchains that periodically roll up their transactions to Layer 1 blockchains like Ethereum. This approach provides the security of Ethereum while maintaining high transaction speeds.
Some of the other popular Layer-2 Blockchains are Arbitrum, Avalanche, Starknet, etc.
Roadmap to Learn Web3
If you’re considering joining a Web3 cohort or want to learn on your own, understanding the syllabus is crucial. Here is the list of concepts and topics you must learn that can help you to understand what we web3, how to develop Smart Contracts for Ethereum Blockchain, and more.
Web3 Foundation
Let’s Start with the basics of Web3, this includes understanding what blockchains are, the principles of decentralization, and key concepts like public and private keys, gas transactions, and cryptography.
Wallet Development
Building a web-based wallet will teach you how wallets work and how they interact with the blockchain. You’ll learn to connect to RPCs, manage token balances, and understand the security implications of wallet development.
Handling Transactions
Understanding how to track and parse blockchain transactions is fundamental. You’ll create a portfolio tracker or a transaction scanning website to get hands-on experience with real-world blockchain data.
Decentralized Exchange (DEX)
Dive into the world of decentralized exchanges (DEXs): Learn about liquidity pools, automated market makers (AMMs), and how to create your own token. This section will also cover building swap functionalities for your applications.
NFTs and NFT Marketplaces
NFTs have become a significant part of the blockchain ecosystem. You’ll learn to create and operate NFT marketplaces, understanding the nuances of buying, selling, and managing NFTs.
Build Web3 Projects
Building projects is one of the best ways to learn. Here are some ideas to get you started:
Build a Token Dex dApp On the Sui Blockchain
A hands-on course that equips you with the skill to build an efficient and quality token swap dApp on the Sui blockchain. Build a token Dex dApp on Sui blockchain
