Learn Blockchain, Solidity, and Full Stack Web3 Development with JavaScript – 32-Hour Course

·

Mastering blockchain development in 2025 means going beyond theory and diving into real-world applications. This comprehensive 32-hour course is your ultimate gateway to becoming a proficient Web3 developer, covering everything from blockchain fundamentals to full-stack decentralized applications (dapps). Whether you're a beginner or an experienced coder looking to transition into the decentralized world, this guide breaks down complex concepts into digestible, hands-on lessons.

You'll gain practical experience with Solidity, Ethereum, JavaScript, TypeScript, Hardhat, Chainlink, IPFS, DAOs, and more. By the end, you'll have built multiple smart contracts, launched DeFi protocols, created NFT marketplaces, and even upgraded live contracts—skills highly sought after in today’s Web3 job market.

🔗 Why This Course Stands Out

Unlike passive tutorials, this course emphasizes learning by doing. Each module includes coding exercises, project walkthroughs, and real-time debugging so you build muscle memory for Web3 development. You'll follow along with expert instructor Patrick Collins as he guides you through every line of code.

👉 Start building your first smart contract today and join the Web3 revolution.

📚 Core Curriculum Breakdown

Lesson 0–1: Blockchain Basics & Fundamentals

Begin with a strong foundation. Understand what blockchain is, how decentralization works, and why trustless systems are reshaping finance and data ownership. Explore consensus mechanisms like Proof of Stake and the role of nodes in maintaining network integrity.

Lessons 2–4: Getting Started with Remix

Dive into Remix IDE—a browser-based environment perfect for beginners. Build your first smart contract: a simple storage system. Then evolve it into a factory pattern that deploys multiple instances. Learn how to interact with contracts using MetaMask and testnets.

Lessons 5–7: Mastering Hardhat & Ethers.js

Transition to professional tooling with Hardhat and Ethers.js. Set up local development environments, write deploy scripts, run tests, and debug with console.log (yes, it's possible in Solidity now!). Build a fully functional "Fund Me" dapp where users can send ETH and withdraw funds based on ownership.

Lessons 8 & 10: Full-Stack Web3 Integration

Connect your smart contracts to the frontend using HTML/JavaScript and Next.js. Learn how to use event listeners, connect wallets via Web3Modal, and display blockchain data dynamically on the page. This is where your dapp starts feeling like a real product.

👉 Unlock full-stack Web3 skills and create dapps that users actually interact with.

Lessons 9 & 10: Smart Contract Lottery

Implement a verifiably fair lottery system powered by Chainlink VRF (Verifiable Random Function). Understand how oracles bring external data securely onto the blockchain and prevent manipulation in random number generation.

Lessons 11–14: DeFi & Token Engineering

Explore the heart of decentralized finance:

These modules prepare you for high-demand roles in DeFi development and tokenomics design.

Lesson 15: NextJS NFT Marketplace

Build a full-stack NFT marketplace where users can mint, list, buy, and sell digital assets. Use Next.js API routes, Pinata, and Web3.js to handle uploads and transactions seamlessly across Ethereum testnets.

Lessons 16–17: Advanced Patterns – Upgrades & DAOs

Learn how to make smart contracts upgradable using proxy patterns—a critical skill for production environments. Then, create a Decentralized Autonomous Organization (DAO) where token holders vote on proposals, simulating real governance models used by major protocols.

Lesson 18: Security & Auditing Best Practices

Security is non-negotiable in Web3. Discover common vulnerabilities like reentrancy attacks, overflow errors, and access control flaws. Use tools like Slither and MythX to audit your code and adopt industry-standard defensive programming techniques.

❓ Frequently Asked Questions

What prerequisites do I need for this course?

Basic knowledge of JavaScript is recommended but not required. Familiarity with command-line tools and Git will help, but the course walks you through setup step-by-step.

Can I get a job after completing this course?

Absolutely. The skills taught—especially in Solidity, Hardhat, and DeFi—are in high demand. Many graduates have landed roles at Web3 startups, DAOs, and blockchain consultancies.

Is the course free?

Yes! All video content is freely available. No download links or paid tiers are needed to access the full curriculum.

How long should I expect to spend on each section?

With over 32 hours of content, plan for 6–8 weeks of consistent study at 5–6 hours per week. Hands-on practice is key—don’t rush through coding exercises.

Do I need to know TypeScript?

While TypeScript is used in some frontend sections, the core concepts are taught in JavaScript first. You’ll pick up TypeScript basics naturally during full-stack projects.

Are certificates provided?

While no formal certificate is issued, you can showcase your completed projects on GitHub as proof of skill—a common practice in the developer community.
