Financial Security is based on Blockchain for Secure Money Transfer with a Hyperledger Policy

Motivation: Blockchain is a decentralized ledger that exchanges virtual money and enables safe transactions. Any network user can access the latest encrypted ledger version to validate a new transaction. This promotes financial system transparency, immutability, and confidence while reducing an over-reliance on conventional intermediaries and preventing fraud. Within the economic realm, blockchain is leveraged as a proof-to-proof structure for secure money transfers to ensure unbreachable financial security and enhanced operational efficiency. Security devices are prone to new cyber threats because them depend on ancient authentication and encryption techniques. Problem: The primary focus of previous blockchain-based financial security solutions is consensus and hashing. However, them proved entirely secured by cryptography, resulting in scalability problems, high processing costs, security flaws, and insufficient encryption for critical transactions. Proposed approach: proposed a blockchain-based financial security framework integrated with Hyperledger policies and advanced cryptographic techniques. In the first step, the Rivest Shamir Adleman (RSA) method creates blocks in financial security. The Diffie-Hellman Key Exchange (DHKE) generates cryptographically secure keys in the second step, protecting private financial data while encrypted. Finally, the Elliptic Curve Digital Signature Algorithm (ECDSA) is applied to data encryption and decryption to provide robust financial security. In addition, smart contracts reduce human errors and fraudulent activities in financial regulatory information by effectively authenticating transactions. Experimental results: ECDSA enhances security with 85.9% performance, encrypts in 11.5 ms, decrypts in 9.2 ms, processes 600 TPS, and reduces authentication delay by 2 ms, ensuring secure, efficient transactions.
