Finanças Descentralizadas em Redes Blockchain: Perspectivas sobre Pesquisa e Inovação em Aplicações, Interoperabilidade e Segurança

Abstract

The support for smart contracts in blockchain networks has led to the emergence of a decentralized and automated finance ecosystem, DeFi (Decentralized Finance).The DeFi ecosystem aims to enhance traditional financial services through token trading, to reduce intermediaries and barriers to credit, and to broaden access to financial services in the context of the decentralized web.In this chapter, we provide an in-depth discussion of three essential and driving aspects of the DeFi ecosystem: (1) innovative applications, (2) interoperability between blockchain networks, and (3) security of the decentralized protocols that rule blockchain.In this sense, we currently present the fundamentals and practical examples of the most popular DeFi applications.We also discuss state-of-the-art research focusing on the three aspects above that will support the growth of DeFi in the coming years.
