Blockchain & Web3 Development

By understanding how cryptographic functions ensure trust and how decentralized networks enable transparent, tamper-proof transactions, learners gain the foundational knowledge needed to navigate and build in the blockchain space.

This lesson explores the different consensus mechanisms - like Proof of Work, Proof of Stake, and variants such as DPoS - and the trade-offs related to speed, energy consumption, and overall network security, emphasizing how consensus choices directly influence user experience, scalability, and the sustainability of decentralized systems.

This lesson provides a practical lens through which to explore running nodes, parsing transactions, and appreciating the robust security model that makes Bitcoin the benchmark for decentralized cryptocurrencies.

By understanding Ethereum’s account-based system, the Ethereum Virtual Machine (EVM), and the role of gas in powering transactions, learners can grasp how Ethereum supports a thriving ecosystem of decentralized applications (dApps).

By exploring smart contract structure, coding patterns, debugging, and testing strategies, learners will gain the fundamental skills necessary to launch robust and secure decentralized solutions on Ethereum.

In this lesson, we explore DApp architecture, walk through real-world coding examples, and discuss best practices for creating interactive, blockchain-driven applications.

This lesson delves into advanced patterns, such as the Factory, Proxy, and Registry patterns. By mastering these concepts—along with robust approaches to ownership and access control—teams can build production-ready smart contracts that remain secure, flexible, and maintainable over time.

By understanding core DeFi concepts like Automated Market Makers (AMMs), lending and borrowing platforms, and yield strategies, learners can grasp how decentralized protocols are reshaping the global financial landscape.

This lesson takes a holistic approach to asset creation, starting with the foundations of forking a blockchain or deploying an ERC-20 token, then moving into the realm of Non-Fungible Tokens (NFTs) and their applications in gaming, metaverses, and digital identity.

This lesson explores the fundamentals of permissioned blockchains, highlighting how frameworks like Hyperledger Fabric, R3 Corda, and Quorum cater to business needs. Learners will discover how identity management, governance models, and performance considerations differ from public networks—equipping them to architect robust, enterprise-grade blockchain systems.

In this lesson, we explore different Layer 2 approaches—such as state channels, sidechains, and rollups—and examine the trade-offs between decentralization, performance, and user experience. By deploying contracts on Layer 2 testnets and comparing costs, learners gain practical insights into scaling strategies for real-world dApps.

This lesson equips learners with the skills to identify, analyze, and mitigate common blockchain vulnerabilities—like re-entrancy and integer overflow—while emphasizing best practices for secure development.

This lesson explores the various models of DAO governance, the technology stacks that support them (e.g., Aragon, DAOstack, Colony), and the legal considerations of running decentralized organizations in the real world.

This lesson explores bridging solutions, cross-chain protocols like Cosmos IBC and Polkadot parachains, and the security trade-offs inherent in connecting separate ledgers.
