GeoPay Payments Network Using Blockchain

This research paper introduces the GeoPay Payments Network, a hybrid blockchain-based payment system that combines Ethereum smart contracts with a backend (Node.js and MongoDB). The study focuses on increasing transaction efficiency, lowering costs, and maintaining security. We compare the performance of public blockchain transactions with proprietary backend processing, providing insights into the trade-offs. The experimental results demonstrate the effectiveness of this hybrid strategy in improving decentralized finance (DeFi) applications.
