Advances in Blockchain and IoT Applications for Secure, Transparent, and Scalable Digital Financial Transactions

This paper explores the convergence of Blockchain and Internet of Things (IoT) technologies and their transformative potential in digital financial transactions. With the rise of decentralized systems, blockchain provides a secure, transparent, and immutable ledger for recording financial transactions, while IoT enables real-time data collection and automation in financial networks. The integration of these two technologies offers enhanced scalability, security, and efficiency, significantly improving the performance of digital financial systems. However, the combination of blockchain and IoT introduces new challenges, including security vulnerabilities, privacy concerns, and the need for effective mitigation strategies. The paper highlights key trends, such as the rise of smart contracts, tokenization, decentralized finance (DeFi) applications, and the incorporation of artificial intelligence (AI) and machine learning (ML) to optimize blockchain-IoT ecosystems. It also examines the evolving regulatory and ethical considerations for these hybrid systems. As these technologies continue to mature, understanding their potential and addressing their associated risks will be critical for the future of digital financial transactions.
