Modified SHA256 for Securing Online Transactions based on Blockchain Mechanism

Abstract

This research is composed of online transaction security; the mechanism of blockchain and proposed a modified SHA256 security protocol through smart contract to secure online transaction procedure specifically based on Blockchain Mechanism. It focus on the discussion of modifying security protocol specifically designed for practical applications of blockchain with particular reference to privacy and trust. The researcher recommend a new transaction procedure involving customer and merchant, permitting entities to recognize one another enabling them to proceed with their transactions securely using Blockchain Mechanism
