Decentralized Financial Systems: Technologies, Platforms, and Applications for Digital Business

Decentralized finance (DeFi) represents a transformative shift in financial services, offering transparent, autonomous, and peer-to-peer interactions without reliance on traditional intermediaries. This paper provides a comprehensive overview of the technological foundations, platforms, and applications of DeFi within the context of digital business. It analyzes core components such as blockchain, consensus mechanisms, smart contracts, and decentralized distributed networks that enable secure and immutable financial operations. The study further explores key financial applications, including asset tokenization, decentralized exchanges, and lending protocols, emphasizing their potential to improve efficiency and create new business models. Additionally, the paper critically examines the main challenges facing DeFi, particularly regulatory uncertainty, security vulnerabilities, and scalability limitations. By demystifying complex technical aspects, the paper aims to equip business professionals with the knowledge necessary to assess the potential and risks of DeFi technologies in modern digital ecosystems.
