In the modern era, logging systems are indispensable for monitoring operations, diagnosing issues, maintaining security, and ensuring compliance in software systems. However, traditional logging systems face significant challenges in guaranteeing data integrity and security, especially against internal threats. This paper proposes a blockchain-based logging solution to address these limitations by ensuring immutability, security, and verifiability of logs. The model leverages blockchain technology to create tamper-proof log chains, integrates seamlessly into existing systems via APIs, and is evaluated in real-world applications. The results demonstrate the model’s ability to significantly enhance security and operational efficiency, making it suitable for critical domains requiring robust logging mechanisms.
