Abstract: Blockchain technology has emerged as a revolutionary tool for securing online transactions by providing a decentralized, transparent, and immutable ledger for digital records. This technology operates on the principles of cryptography and consensus mechanisms, making it resistant to tampering and fraud. As online transactions have become an essential part of modern economies, ensuring the security and integrity of these transactions has become a critical challenge. Blockchain addresses these concerns by enabling peer-to-peer transactions without the need for intermediaries, thereby reducing the risk of fraud, data breaches, and financial theft. The purpose of this paper is to explore the role of blockchain technology in enhancing the security of online transactions, focusing on its implementation in various industries such as finance, healthcare, and e-commerce. This paper will analyze the fundamental features of blockchain, including its decentralized nature, transparency, and the cryptographic techniques used to ensure data integrity. Additionally, it will examine the challenges associated with the widespread adoption of blockchain, including scalability issues, regulatory concerns, and technological barriers. The paper also discusses the future potential of blockchain technology, particularly in relation to its integration with emerging technologies like artificial intelligence and the Internet of Things. By reviewing current trends, case studies, and research findings, this paper aims to provide a comprehensive analysis of blockchain technology’s impact on securing online transactions and its potential to revolutionize digital economies.
