Blockchain technology has emerged as a powerful solution for improving the security, transparency, and efficiency of financial transactions. Unlike traditional financial systems that depend on centralized intermediaries, blockchain uses decentralized distributed ledgers, cryptographic security, consensus mechanisms, and immutable records to ensure trust and data integrity. This study examines the role of blockchain in securing financial transactions and explores its core components, including distributed ledgers, cryptographic hashing, consensus protocols, smart contracts, and decentralized networks. The research analyzes how blockchain mitigates security threats such as fraud, double spending, identity theft, unauthorized access, and transaction tampering. It also investigates applications in digital payments, cross-border remittances, banking, trade finance, cryptocurrencies, and decentralized finance (DeFi). A blockchain-enabled financial transaction framework is proposed and evaluated using metrics such as security, transparency, scalability, efficiency, and fraud prevention. The findings indicate that blockchain significantly enhances transaction security and transparency while reducing costs and processing times. Although challenges such as scalability, regulatory issues, interoperability, and energy consumption remain, blockchain demonstrates strong potential to transform modern financial systems and support the development of secure, efficient, and decentralized financial ecosystems.
