Introduction

### Course Review: Decentralized Finance (DeFi) Infrastructure In the ever-evolving world of finance, innovations come and go, but few have captured the imagination and potential of a global audience as decentralized finance (DeFi) has. If you're eager to understand the foundations and implications of this revolutionary system, the **Decentralized Finance (DeFi) Infrastructure** course on Coursera, taught by the esteemed Professor Campbell R. Harvey from Duke University, is a must-enroll opportunity. #### Course Overview **Decentralized Finance: The Future of Finance** is a comprehensive set of four courses that delve deep into the principles, history, and future of DeFi. This introductory course lays the groundwork by tracing the evolution of financial systems from ancient barter economies to the digital innovations of today. The course shines a light on significant financial concepts while providing students with the crucial knowledge required to navigate this burgeoning field. #### Syllabus Breakdown 1. **The History of Decentralized Finance** In this opening module, Professor Harvey takes us on a fascinating journey through financial history, beginning with the earliest barter exchanges and progressing through the advent of specie and fiat currencies. The highlights include a critical examination of the inefficiencies inherent in the current financial system, culminating in an insightful review of Satoshi Nakamoto's groundbreaking 2008 paper that introduced cryptocurrency. This historical perspective is vital for understanding how DeFi emerged as a response to systemic challenges in traditional finance. 2. **DeFi Foundations** Here, the course introduces the essential mechanisms that enable DeFi, particularly focusing on blockchain technology and cryptographic hashing. The exploration of smart contracts—automated, self-executing contracts without the need for intermediaries—provides a key insight into how decentralized applications can operate securely and efficiently. Additionally, distinguishing between early cryptocurrencies and stablecoins equips students with practical knowledge relevant for real-world applications. 3. **Problems DeFi Solves** This module addresses the shortcomings of the existing financial paradigm, including inefficiencies, limited access, opacity, centralized control, and interoperability issues. By dissecting each of these problems, students can appreciate how DeFi solutions seek to democratize finance, making it more accessible, transparent, and efficient. This analysis is not only theoretical but also contextualizes the urgent need for innovations in the financial sector in today's world. 4. **DeFi Myths and Facts** The final module tackles prevalent misconceptions surrounding DeFi and cryptocurrencies. Students will learn to discern between myths and reality, gaining a nuanced understanding of issues like anonymity in transactions, security concerns about blockchains, and the limitations posed by quantum computing. This critical analysis empowers learners to approach DeFi with a balanced perspective, recognizing both its possibilities and constraints. #### Course Experience Professor Harvey's teaching style is engaging and informative, seamlessly blending historical context with modern-day applications. Each module is well-structured, featuring videos, readings, and discussion prompts that encourage active engagement. The course also provides opportunities for networking with fellow learners, adding an extra layer of value through community interaction. #### Recommendation I wholeheartedly recommend the **Decentralized Finance (DeFi) Infrastructure** course for anyone interested in finance, technology, or innovation. Whether you're a seasoned finance professional or a curious beginner, this course offers essential insights into a field that is shaping the future of money and financial systems. With the growing emphasis on digital currencies and decentralized models, being well-versed in DeFi is not just advantageous—it's increasingly essential. Enroll in this course to equip yourself with the knowledge and skills necessary to thrive in this dynamic landscape.

Syllabus

The History of Decentralized Finance

This module provides a historical perspective of exchange beginning with early barter, specie currency (backed by, e.g., gold), fiat currency and electronic transfers. The module introduces some of the key problems that have arisen with the current system. It closes with the introduction to Satoshi Nakamoto’s famous 2008 paper which introduced cryptocurrency.

This module introduces the key foundations for DeFi, starting with the mechanics of blockchain including cryptographic hashing. The module then explores the innovation of smart contracting - a key ingredient for DeFi. There is also a discussion of the differences between the first cryptos and stablecoins.

This module explores the key problems with today’s legacy financial system which include: inefficiency (costly, slow, and insecure transactions); limited access (many cannot access banks and many that have bank accounts find it difficult to get loans); opacity (it is unclear how healthy our commercial financial institutions are); centralized control (current system is dominated by oligopolies that push prices higher than competitive prices) and interoperability (difficulty in moving funds across different legacy financial institutions).

The final module explores various different myths including: all cryptocurrencies are anonymous; blockchains are routinely hacked; quantum computing will destroy all blockchain based currencies; and the crypto ecosystem is so small that it is unlikely to compete with legacy financial institutions.
