Explore the transformative world of Decentralized Finance (DeFi), where financial services operate on blockchain technology without traditional intermediaries. Understand its core properties, technology stack, and the potential impact on global finance.
This chapter delves into the foundational concepts of blockchain technology, tracing its evolution from Bitcoin's inception to modern scaling solutions and cross-chain interoperability that are shaping the future of decentralized finance.
Dive into smart contracts, the foundational technology powering DeFi. Learn how programmable contracts execute automatically on blockchains, enabling trustless financial applications and decentralized protocols.
Master blockchain oracles and how they bring external data on-chain. Learn about the oracle problem, Chainlink's decentralized networks, price feeds, and best practices for using oracles securely in DeFi protocols.
Learn about Decentralized Identifiers (DIDs), the W3C standard for self-sovereign identity, including DID methods, resolution, and authentication flows.
Explore the challenges and solutions of decentralized identity in blockchain, addressing Sybil attacks, governance, and undercollateralized lending while maintaining privacy and inclusivity.
Master the fundamentals of Decentralized Finance (DeFi) and learn how blockchain technology is revolutionizing traditional financial services through permissionless protocols and smart contracts.
Explore the vulnerabilities in DeFi smart contracts that have led to billions in losses. Learn about common exploits such as reentrancy, access control flaws, and more, with real-world examples like the Poly Network hack.
Explore the complexities of DeFi security, focusing on advanced attacks like bridge vulnerabilities, economic exploits, and the systemic risks they pose to the blockchain ecosystem.
Explore real-world applications of decentralized identity including Gitcoin Passport, IPFS for content addressing, quadratic funding with Sybil resistance, and practical use cases in lending, governance, and social networks.
Explore privacy considerations in decentralized identity, emerging trends, open questions, and the future of self-sovereign identity systems in Web3.
Explore Proof of Personhood systems including Worldcoin's biometric verification, Proof of Humanity's video verification, and BrightID's social graph approach to proving unique humanness.
Learn about Soulbound Tokens (SBTs) for non-transferable reputation and ENS (Ethereum Name Service) for human-readable blockchain addresses and rich identity profiles.
Learn about Verifiable Credentials (VCs), zero-knowledge proofs for selective disclosure, and credential revocation mechanisms for decentralized identity systems.
