Bank-Guard Fusion System

This paper introduces Bank-Guard Fusion System, a decentralized blockchain wallet system designed for secure cryptocurrency management. Utilizing blockchain's decentralized, cryptographic strengths, the platform enables wallet creation, balance checks, and transactions in a user- friendly, secure environment. Built with React.js, Flask, and MongoDB, it provides a seamless interface and decentralized data handling. Integrating Proof of Work (PoW) and Proof of Stake (PoS) for transaction validation, this solution enhances trust, transparency, and security, bridging users and blockchain technology to facilitate sustainable, scalable, and robust digital transactions.
