Cyberspace is a complex place since multitasking applications and legal requirements are involved. Smart contracts, which are a profound change for the better in terms of security within the distributed framework, have been one of the major revolutions in recent times. Allowing the effective use of blockchain technology guarantees that the execution of the agreed protocols is both automated and secure, ensuring that these actions are indisputable. This, in turn, enables the efficient handling of cyber threats through the implementation of various cybersecurity measures. Besides, the dependency on weaker forms of authority is consequently minimized; thus, the vulnerabilities as well as the points that can be used by malicious attacks are fewer. Hence, the decentralized nature of smart contracts enhances communication between nodes, enabling them to communicate more clearly and effectively. Consequently, the entire system’s resilience is improved. Furthermore, since it is possible to make some kinds of attacks automatically in real time, event management is facilitated, and damage control is done in a better way. The idea of smart contracts, incorporated in a distributed way of environments, is the topic of this research paper, which points out the ability of smart contracts to turn the traditional threat detection and response model into a much more reliable and independent cybersecurity model.
