Enhance Security for the E-payment Application with Blockchain Technology

E-payment systems, despite their practicality, face challenges such as data manipulation, limited bandwidth, and potential denial-of-service attacks. These issues can impact businesses, financial institutions, and individual users conducting transactions, as they struggle to manage large amounts of traffic simultaneously. Addressing these issues is crucial for ensuring secure and efficient transactions. This research presents a system that integrates Hyperledger Fabric with software-defined networking to enhance system throughput without significantly altering the Blockchain’s functionality. It also uses Hyperledger Aries technology for improved client identity recognition efficiency. The proposed system aims to reduce deployment time, maintain secure data, and provide a non-stop payment platform for client identification within a decentralized framework. It supports multiple concurrent users or system attacks with minimal average delay, ensuring efficient communication among components. The system is being researched to find a feasible solution that balances security and performance in real time while minimizing internal platform modifications.
