Blockchain-Enabled Smart Contracts for IoT: Enhancing the Reliability of Electronic Evidence

Abstract

The fast spread of Internet of Things (IoT) devices has created major difficulties to uphold data security and maintain its reliability and integrity for interconnected systems. Traditional centralized systems cannot protect electronic evidence sufficiently in zero-trust environments because they lead to evidence that becomes vulnerable to unauthorized tampering. Blockchain technology solves these issues effectively through decentralized data processing and unalterable databases that remain easily viewable to all users. The research investigates blockchain smart contracts as a solution to improve IoT electronic evidence reliability by implementing automated access verification and data integrity assessment and event activation. Automated smart contract technology establishes transparent data security through policy enforcement which happens without third-party organizations. The research demonstrates how blockchain technology and smart contracts assist different industries like healthcare facilities and supply chains and industrial Internet devices and smart cities to operate. This research describes the principal obstacles within the field like scalability problems together with resource constraints and legal complications while offering recommendations about possible future academic investigations. Through blockchain technology alongside smart contracts this research develops a framework which enhances the reliability and security of IoT electronic evidence while benefiting IoT ecosystem reliability and safety.
