Crypto and DeFi

Abstract

This chapter delves into how cryptocurrencies and decentralized finance are transforming the traditional financial landscape. The chapter explains how digital currencies enable peer-to-peer transactions without intermediaries, making transfers faster, cheaper, and more secure. It then expands on DeFi, where financial services such as lending, borrowing, and trading are reimagined through smart contracts and blockchain technology, eliminating centralized gatekeepers. Real-world comparisons illustrate the advantages of DeFi over traditional finance, including lower fees, enhanced transparency, and greater accessibility for underserved populations. The discussion also covers the technological underpinnings – Layer 1 and Layer 2 solutions, smart contracts, and consensus mechanisms – highlighting how these innovations create a more inclusive, efficient, and trustless financial ecosystem.
