A Blockchain-Based Mobile Payment System for Secure Transaction

Blockchain technology has emerged as a solution to the bank's problem, acting as a middleman in traditional and online banking systems. It enables peer-to-peer transactions and protects people's financial information, even from the bank. Mobile payment application users are now prevalent in rural and urban areas of Bangladesh. In this case, a cryptocurrency-based unified payment interface (UPI) with the ability to provide additional security and significant performance improvement can be helpful. Bangladesh’s neighbour India has already built such a system. Then China also followed suit. This paper worked on a similar system that allows mobile devices to mine blocks and create their transactions without relying on bank servers.
