Opportunities to Achieve Cyber Security Through Blockchain and Smart Contracts

In the context of growing threats in the digital space, cyber security has established itself as a critical component for protecting information systems. With the increasing reliance on digital technology and the Internet, the risks of cyber-attacks and unauthorized access to sensitive data have greatly increased. This highlights the need to develop advanced security mechanisms that ensure the overall safety of systems. Traditional security methods often fail to cope with the complexity of modern threats. Organizations are therefore exploring new technologies, such as blockchain and artificial intelligence, that offer higher levels of security. Blockchain provides innovative solutions that decentralize identity management and reduce dependence on centralized servers. This paper aims to present a methodology combining two blockchain authentication methods – MetaMask Authentication and Smart Contract-Based Authentication, for implementation and analysis, ensuring overcoming challenges in real applications.
