Security and efficiency improvement of internet financial payment based on blockchain technology

The demand for secure, effective, and scalable payment systems has increased due to the rise of Internet-based financial transactions. Through traditional techniques, such as Proof of Work (PoW), conventional financial systems often encounter issues with high transaction latency, concerns about fraud, and excessive energy consumption. These problems are widespread in traditional systems. This research proposes a Secure Hybrid Consensus Protocol (SHCP) with the intention of enhancing the effectiveness, velocity, and reliability of financial transactions based on Blockchain technology. The Proof of Stake (PoS) protocol is combined with the Byzantine Fault Tolerance (BFT) protocol by SHCP. Through the utilization of adaptive prioritization, Bayesian inference, and anomaly recognition, SHCP can incorporate the most advanced fraud detection technology. The SHCP framework uses anomaly recognition to identify fraud with 92% accuracy, 38% faster validation, and 43% less energy than PoW-based systems. The system delivers ~ 7,000 TPS (Transactions Per Second) and a 27% increase in decision risk prediction stability. Anomaly scoring, Bayesian inference, and adaptive prioritization aid fraud detection. These advances enable safe, rapid, and affordable financial transactions, creating a sustainable Blockchain-based payment ecosystem.
