The intersection of blockchain technology and artificial intelligence (AI) in finance represents a transformative evolution in how financial services and transactions are conducted. Blockchain offers transparency, security, and immutability, while AI brings data analysis, automation, and decision-making capabilities. Together, these technologies have the potential to reshape financial systems, enhancing operational efficiency, improving fraud detection, enabling smarter contracts, and ensuring more secure and personalized financial services. This chapter explores the synergies between blockchain and AI, examining their individual contributions to finance and how their integration can address challenges like fraud, data privacy, and compliance. It also investigates real-world applications, including decentralized finance (DeFi), risk management, and algorithmic trading, and looks at the future possibilities for these technologies in the financial sector.
