Abstract
Ensuring the data integrity and safety of dam infrastructure is a major challenge. In recent years, numerous cyberattacks have targeted critical infrastructure, underscoring the importance of security systems. To address this challenge, we propose DamChain, a warning system designed to improve the data integrity and security of dam infrastructure based on blockchain technology. The decentralized ledger of blockchain records data in a transparent and immutable manner, which is important for ensuring the integrity of data and preventing unauthorized modification. This system aims to provide a solution that maintains the data integrity and is designed to provide a warning mechanism about water levels, improving the security and data integrity of dams.
