Analysis of the Application of Blockchain Technology in Digital Payment Systems to Enhance Transaction Security

The rapid growth of digital payment systems, such as e-wallets, online banking, and fintech platforms, has transformed financial transactions by offering convenience and efficiency. However, these systems remain vulnerable to fraud, identity theft, double-spending, and data breaches, raising critical concerns about transaction security. This research analyzes the application of blockchain technology in digital payment systems with a focus on improving transaction security. Employing a qualitative approach supported by a review of existing literature, the study examines blockchain’s effectiveness in preventing fraudulent activities, enhancing transparency, and fostering trust among users. The findings indicate that blockchain’s decentralized and immutable ledger, combined with cryptographic mechanisms, provides strong safeguards against unauthorized access while also reducing costs and processing times. Nonetheless, challenges such as scalability issues, high energy consumption, regulatory uncertainty, and integration complexities hinder its widespread adoption. The study concludes that blockchain represents a promising innovation for securing digital payment systems, though its success requires regulatory adaptation, technological improvement, and cross-sector collaboration. The research offers important implications for businesses seeking secure payment solutions, consumers demanding trust and safety, regulators tasked with designing supportive frameworks, and academics contributing to the evolving discourse on digital finance.
