If you're eager to dive into Web3 and blockchain development, this repository serves as a comprehensive resource to help you become proficient in the field. It provides materials that cater to both novices and experienced developers, allowing you to tailor your learning based on your current expertise. Progression in learning should be gradual—rushing into advanced topics without mastering the basics can lead to confusion and hinder your success.
A blockchain is a decentralized system that records transactions in a transparent and unalterable manner. This video by 3Blue1Brown offers a simple yet informative breakdown of how Bitcoin operates, making it perfect for newcomers.
While there are many blockchain platforms available, the two most influential ones are:
The video mentioned above is an ideal starting point for understanding Bitcoin. For those looking to explore further, Grokking Bitcoin is a highly recommended resource. It also helps to delve into the Bitcoin Whitepaper, which lays the foundation of how Bitcoin operates.
For those interested in cryptographic details, the book provides a deep dive into the technical aspects. Though the content can become more complex after the initial chapters, gaining a thorough understanding of Bitcoin is essential, as it has paved the way for all modern blockchain technology. To visualize key blockchain concepts like hashing and blocks, try using this demo by Andreas Brownworth.
Additionally, you can explore Cryptohacks for puzzles that teach cryptography concepts, including Elliptic Curve Cryptography, which is integral to various blockchain systems like Bitcoin and Ethereum.
Regardless of which blockchain you aim to build on, learning Bitcoin's foundational structure is crucial. After that, the next logical step for anyone serious about Bitcoin development is to study Mastering Bitcoin by Andreas M. Antonopoulos.
With this foundation, you'll be ready to contribute to open-source blockchain projects and apply for initiatives like Summer of Bitcoin.
Bitcoin’s primary focus was to create a decentralized payment system, but Ethereum expanded on that by enabling programmable smart contracts. The Ethereum Virtual Machine (EVM) allows developers to implement complex logic on the blockchain, offering functionality far beyond simple financial transactions.
For a broad introduction to Ethereum, visit the Ethereum Foundation and explore its content. Reading the Ethereum Whitepaper is also essential for understanding how Ethereum distinguishes itself from Bitcoin.
Having a basic understanding of Ethereum is enough to start developing decentralized applications (DApps), but the EVM is highly intricate. Beginners should pause at this stage, gain experience by working on projects, and return to advanced topics later. To become a proficient blockchain developer, you’ll need skills in:
DApps are essentially web applications with a blockchain backend like Ethereum. Therefore, solid Web2 development skills are necessary for building a fully functional DApp. You’ll need to integrate frontends with smart contracts and manage backend services for various SDKs and APIs.
Important Web2 topics include:
- Mastering HTML and CSS for creating responsive and user-friendly frontends.
- JavaScript essentials, such as variables, loops, functions, and async programming (W3Schools JavaScript Tutorial).
- Node.js basics: npm, handling dependencies, and setting up package.json files.
- Working with APIs and making HTTP requests.
- JavaScript libraries like Ethers.js and Web3.js, which allow you to connect your frontend to Ethereum.
Familiarity with JavaScript frameworks like React.js or Next.js is also valuable for building sophisticated applications.
The heart of every DApp lies in smart contracts, and Solidity is the go-to language for writing them. The best way to grasp Solidity is through interactive learning, and platforms like CryptoZombies teach Solidity through engaging projects.
For those looking to deepen their knowledge, Solidity by Example offers concise explanations of key concepts. Patrick Collins also provides an extensive Blockchain Development Course, which is ideal for gaining a thorough understanding of Solidity and the Web3 ecosystem.
If you prefer a more interactive, structured learning environment, LearnWeb3DAO is another excellent option, especially for beginners with no prior blockchain experience.
While learning Solidity, it’s essential to familiarize yourself with the broader Web3 ecosystem. Understanding the variety of existing protocols helps identify problems within the ecosystem and ways to contribute. Some helpful YouTube channels include:
To dive deeper into DeFi protocols, reading whitepapers is highly recommended:
Mastering Solidity is just the beginning. Writing secure, optimized smart contracts requires a deep understanding of how the EVM operates. Optimizing for gas efficiency and ensuring security against potential vulnerabilities are key priorities for any blockchain developer.
For those looking to sharpen their EVM knowledge, here are some valuable resources:
If smart contract security interests you, consider joining the Secureum Bootcamp, which focuses on security best practices. You can also practice through platforms like Ethernaut and participate in security contests via Code4rena or Immunefi.
